Description

Air conditioner outdoor unit cooling device and air conditioner outdoor unit using the same

The present invention relates to a cooling device for an air conditioner outdoor unit and an air conditioner outdoor unit using the same, and more specifically, relates to a cooling device that improves heat exchange efficiency in the outdoor unit body and reduces power consumption during cooling.

With the spread of household electrical machinery and appliances, the power consumption of ordinary households has been increasing year by year, and now it is said that ordinary households account for about 30% of the total power consumption. On the other hand, the power supply shortage has become a serious social problem triggered by the Great East Japan Earthquake, and the importance of power saving has been reviewed again.

When trying to save electricity in a general household, one of the home appliances to be considered first is an air conditioner, a so-called air conditioner. In particular, air conditioning accounts for about half of the total power consumption of home households during the summer day, when power consumption dramatically increases due to cooling. First, air-conditioner power saving must be realized.

For example, Patent Documents 1 to 3 are known as the power saving technology related to the air conditioner described above. The invention described in Patent Document 1 is a cooling that improves the heat exchange efficiency in the heat exchanger by spraying cooling water from a spray nozzle built in the outdoor unit body and directly cooling the heat exchanger. Device.

The invention described in Patent Document 2 is a cooling device that directly cools a heat exchanger by bringing a water retaining cloth containing cooling water into contact with the heat exchanger. In the cooling device of Patent Document 2, a water storage tank is installed on the top surface of the outdoor unit main body, and a water retaining cloth is installed at the intake port of the outdoor unit main body. The upper end of the water retaining cloth is lifted, and the cooling water stored in the water reservoir is supplied to the water retaining cloth by being taken in and out of the water reservoir.

The invention described in Patent Document 3 is a cooling device that cools intake air by disposing a mat material in the vicinity of a heat exchanger in an outdoor unit body and causing cooling water to flow through the mat material. That is, the cooling device of Patent Document 3 is a cooling device that indirectly cools the heat exchanger by supplying cooled intake air to the heat exchanger.

However, according to Patent Documents 1 to 3, problems occur in the following points. First, in the cooling device described in Patent Document 1, in addition to the spray nozzle, a water supply line from the water storage facility to the spray nozzle, a drainage line of sprinkled cooling water, and a device for controlling the spraying operation of the spray nozzle are complicated. A costly mechanism is required, which increases the cost.

Moreover, since the spray nozzle according to Patent Document 1 should be built into the outdoor unit body at the design stage and manufacturing stage of the outdoor unit body, it is retrofitted to the outdoor unit currently used. Cannot be used. In other words, in order to introduce the cooling device described in Patent Document 1, it is necessary to purchase an outdoor unit body equipped with an injection nozzle instead of the outdoor unit body currently used. Incurs high costs. Therefore, the invention of Patent Document 1 is poor in effectiveness as a power saving measure in ordinary households.

Since the cooling device described in Patent Document 2 draws the water retaining cloth into the air intake and brings it into contact with the heat exchanger, the water retaining cloth closes the air intake and blows a necessary amount of outside air to the heat exchanger. The problem of disappearing arises. Moreover, it is difficult to make the water retaining cloth uniformly contact the surface of the heat exchanger, and the cooling effect becomes unstable. Therefore, a stable power saving effect cannot be obtained. Furthermore, the cooling device of Patent Document 2 requires a driving mechanism such as a small motor in order to insert and remove the water retaining cloth into and from the water storage tank, and thus increases the cost accordingly.

The cooling device described in Patent Document 3 requires a complicated cooling water supply mechanism such as a device for supplying cooling water to the mat material and a device for controlling the supply operation in addition to the mat material. Invite. Moreover, the supply mechanism should be attached in advance to the interior of the outdoor unit main body at the design stage and manufacturing stage of the outdoor unit main body. That is, even in the invention described in Patent Document 3, as in the invention described in Patent Document 1, a high-cost problem occurs, and the effectiveness as a power saving measure in ordinary households is poor.

Also, in this type of air conditioner, high temperature air (exhaust hot air) is released from the outdoor unit body due to its heat exchange action. This exhausted hot air has an adverse effect on the environment, such as contributing to the heat island phenomenon. Furthermore, the surrounding air to be sucked into the outdoor unit main body is warmed by the exhaust hot air, thereby causing a vicious cycle in which the heat exchange efficiency is lowered. Therefore, in order to reduce adverse effects on the environment and improve the heat exchange efficiency in the outdoor unit body, it is also important to cool the exhaust hot air.

Regarding the above-described exhaust hot air cooling technology, for example, Patent Document 4 discloses a cooling device in which a water retaining cloth is disposed on the exhaust port side of the outdoor unit body to cool the exhaust hot air. In the cooling device described in Patent Document 4, the water retaining cloth is held by the frame body in a deployed state, and the drain water of the outdoor unit main body is supplied to the water retaining cloth from the drain pipe provided on the upper portion of the frame body. The exhaust heat air blown on the water retaining cloth is cooled.

However, since the cooling device of Patent Document 4 supplies cooling water to the water retaining cloth, a space for drawing the drain pipe around the air conditioner outdoor unit main body is required, so depending on the specific arrangement conditions of the outdoor unit main body, The trouble that cannot install a cooling device arises.

By the way, in this kind of cooling device, since the duration of the cooling effect is proportional to the amount of cooling water stored, it is necessary to increase the capacity of the water storage tank, so that the water storage tank is only on the top surface of the outdoor unit body. In the provided configuration, it is difficult to secure a sufficient installation space, and it is not possible to meet the demand for a large storage tank capacity.

Also, this type of outdoor unit main body tends to be installed in a narrow space such as an alley part with a neighbor or a corner of a veranda in order to secure a living space. As a result, in some cases, it may not be possible to secure a space for installing a large-capacity water tank on the top surface. In particular, when the outdoor unit main body is hung on the outer wall surface of a building by the installation device described in Patent Document 5, a large-capacity water storage is provided on the top surface from the viewpoint of preventing a fall accident due to an earthquake or a typhoon. A tank cannot be installed.

The inventions described in Patent Documents 1 to 5 cannot sufficiently meet the above-described demand for increasing the capacity of the water storage tank.

As an example, when the volume of the water storage space 300 is about 16 liters, the diameter of the first drain hole 36 is about 0.2 to 1.0 mm.

The second drainage hole 37 opens to the side of the bottom 33 viewed in the height direction H in the side surface 34 and communicates with the water storage space 300. There are a plurality of second drain holes 37, and the side surfaces 34 are intermittently arranged at intervals in the width direction W. The diameter (internal dimension) of the second drain hole 37 may be the same as that of the first drain hole 36, or may be larger than the diameter of the first drain hole 36. it can.

The lid 32 is detachably attached to the opening 35 and covers the opening 35 to seal the water storage space 300. According to the configuration in which the opening portion 35 is provided with the lid portion 32 and the water storage space 300 is sealed by the lid portion 32, when the cooling water (7) is stored in the water storage space 300, the cooling water (7) by natural evaporation is stored. Reduction can be avoided and the operation period of the cooling device 2 can be extended. The lid portion 32 has a water supply port for injecting cooling water (7) into the surface, and a cap 38 is attached to the water supply port.

3, the opening end of the first drain hole 36 and the opening end of the second drain hole 37 are covered with a clogging prevention filter 39 on the inner surface of the water storage tank 3 in FIG. According to this structure, even when dust or the like is mixed into the cooling water (7) stored in the water tank 3, the cooling water (7) is smoothly discharged through the first and second drain holes 36 and 37. You can continue.

1 and 2, with reference to FIGS. 4 and 5, the cooling unit 4 includes a base portion 41 and a water retaining portion 42. The water retaining part 42 is made of a porous material, is attached to the base part 41, and has a vent hole 43. Specifically, the base portion 41 of FIGS. 4 and 5 is a frame body having a lattice-like portion inside, and has a structure in which a plurality of rod-like members are crossed and joined at respective intersections. With this structure, the base portion 41 has a vertical lattice portion 44 extending in the height direction H and a horizontal lattice portion 45 extending in the width direction W intersecting the height direction H. The vertical lattice portion 44 and the horizontal lattice portion A through portion 46 penetrating in the thickness direction T is formed inside the portion surrounded by the portion 45.

The base portion 41 serves as a bone (support material) for the water retention portion 42, and is made of a rod-shaped member mainly composed of a metal material such as aluminum or stainless steel from the viewpoint of corrosion resistance, weather resistance, impact resistance, and the like. Can be configured. Further, in addition to the above-described viewpoints, a synthetic resin material can also be used from the viewpoint of material cost, processing cost, and the like.

The water retaining part 42 is made of a porous material and is attached to the base part 41. The water retaining part 42 is a porous structure having a synthetic resin material as a main component or a sponge structure. Examples of the synthetic resin material used include polyvinyl alcohol (PVA), polyethylene (PE), polypropylene (PP), vinyl chloride resin (PVC), styrene resin (PS), and PET resin (PET). .

Here, the water retaining part 42 has a porous structure, so that it absorbs water in the pore space, stores the absorbed water for a certain period of time, and then receives external pressure, gravity, heat, water surface tension, etc. Can be discharged according to That is, the “water retention” in the water retention unit 42 means a function that absorbs water, and preferably allows the absorbed water to be discharged after being stored for a certain period.

The water retaining part 42 is formed with a constant thickness around the base part 41 constituting the opening edge of the penetrating part 46, that is, the vertical lattice part 44 and the horizontal lattice part 45 (see FIG. 5). . As a method for forming the water retaining part 42 on the base part 41, for example, a sponge sheet (porous sheet) cut into a strip shape may be wound according to the inner dimension of the through part 46. The substrate portion 41 may be integrally formed by a known coating technique such as immersing in a synthetic resin material solution.

The water retaining part 42 has a vent hole 43. The ventilation hole 43 penetrates the base portion 41 and the water retention portion 42 in the thickness direction T. In other words, the vent hole 43 has the inner surface of the water retaining portion 42 formed on the base portion 41 constituting the opening edge of the through portion 46 as an opening edge, and the opening edge of the vent hole 43. Is a similar shape in which the opening edge of the penetrating portion 46 is reduced. That is, the basic structure of the vent hole 43 is based on the end edge of the base portion 41 that constitutes the through portion 46, and the final opening end is formed by the water retaining portion 42 that uses the end edge of the base portion 41 as the center wire. Is determined.

Referring to FIGS. 1 to 5 again, the basic configuration of the cooling device 2 will be described. The water permeable sheet 5 is made of a porous material, and is disposed on the outer surface of the bottom 33 of the water storage tank 3 so that the surface region on one end side faces the first drain hole 36 across the bent portion, and the surface on the other end side. The region comes into contact with the water retention part 42. The water permeable sheet 5 can have the same structure as the water retention part 42. That is, the water permeable sheet 5 is mainly composed of a synthetic resin material such as polyvinyl alcohol (PVA), polyethylene (PE), polypropylene (PP), vinyl chloride resin (PVC), styrene resin (PS), PET resin (PET), A sheet-like body having a porous structure or a sheet-like body having a sponge structure.

The water permeable sheet 5 is a member that constitutes a supply path of the cooling water (7) from the water storage tank 3 to the water retention unit 42. The “water permeability” of the water permeable sheet 5 means a function capable of absorbing and discharging water. Therefore, as the water-permeable sheet 5, for example, a woven fabric using natural fibers or synthetic fibers, or a nonwoven fabric composed of the same fibers can be used.

Further, the water-permeable sheet 5 is attached to the outer surface of the housing 10 in the combined structure of the cooling device 2 and the outdoor unit body 1. The water-permeable sheet 5 of FIGS. 1 and 2 is installed on the top surface portion 13 and is attached so as to hang from the top surface portion 13 to the side surface portion 14 with the air inlet 12, and the inner surface of the portion depending on the side surface portion 14 is By being in surface contact with the outer surface of the water retention part 42, the water retention part 42 is connected in a water-permeable manner. The surface contact portions between the water permeable sheet 5 and the water retaining portion 42 are preferably bonded to each other leaving a contact area through which water can pass.

The water storage tank 3 is placed on the outer surface of the housing 10 with the water permeable sheet 5 interposed therebetween. The water storage tank 3 of FIGS. 1 and 2 is attached on the top surface 13 so that the bottom 33 faces the water permeable sheet 5. It is preferable that the water storage tank 3 is fixed to the top surface part 13 using a well-known fixing tool (not shown) such as a hook or a string from the viewpoint of preventing overturning.

The cooling unit 4 is attached to the outer surface of the housing 10 and covers the air inlet 12 in the attached state. 1 and 2 is attached to the side surface portion 14 by a pair of hooks 6 and 6, and covers the air inlet 12 in the attached state. The cooling unit 4 has a structure in which only the upper edge portion of the base unit 41 is suspended by a pair of hooks 6, 6, but the mounting structure of the cooling unit 4 to the side surface unit 14 is stable, construction It can be appropriately changed from the viewpoint of efficiency and the like. For example, since this type of outdoor unit main body 1 is literally installed outside the room, the cooling unit 4 is screwed to the side unit 14 at the four corners to install the cooling unit 4 with respect to the side unit 14. Is stable. As a result, it is possible to prevent noise caused by the cooling unit 4 colliding with the side surface part 14 in a strong wind such as a typhoon.

The air conditioner outdoor unit described with reference to FIG. 1 to FIG. 5 has one of the features in that it has a cooling device 2. More specifically, the cooling device 2 of FIG. 1 to FIG. 7) There is one of the features in the supply path for supplying. Then, with reference to FIG.6 and FIG.7 next, the supply path | route of the cooling water (7) in the cooling device 2 is demonstrated.

First, in the cooling device 2 constituting the outdoor unit of the air conditioner, when the cooling water 7 is stored in the water storage tank 3 that is the starting point of the supply path, the cooling water 7 is transmitted from the first drain hole 36 to the water permeable sheet by gravity or the like. 5 (see FIG. 7). The discharged cooling water 7 permeates the inside of the water-permeable sheet 5 radially by the so-called capillary phenomenon with the first drain hole 36 as the center. A part of the cooling water 7 soaked in the water permeable sheet 5 is further supplied to the water retaining part 42 through a contact portion between the water permeable sheet 5 and the water retaining part 42.

According to the above-described structure, the cooling water 7 discharged from the first drain hole 36 penetrates the interior of the water permeable sheet 5 over a wide area, and then passes through the contact portion between the water permeable sheet 5 and the water retaining part 42 to the water retaining part 42. Since the water is supplied, the cooling water 7 is supplied widely and uniformly to the water retaining portion 42 regardless of the opening position and the number of the first drain holes 36.

On the other hand, the water storage tank 3 has a second drain hole 37, and the cooling water 7 is also discharged from the second drain hole 37 to the water permeable sheet 5. The cooling water 7 that has fallen onto the water permeable sheet 5 from the second drain hole 37 passes through the inside of the water permeable sheet 5 and is supplied to the water retaining part 42 through the contact portion between the water permeable sheet 5 and the water retaining part 42. .

The second drainage hole 37 has a larger evaporation amount of the cooling water 7 than the drainage amount from the first drainage hole 37 in the case of extreme heat, and the water-permeable sheet 5 holds a sufficient amount of the cooling water 7. If not, it has a function of replenishing the water-permeable sheet 5 with the cooling water 7. Furthermore, as shown in FIG. 6, the second drainage hole 37 is provided with a vertical lattice portion 44 on an extension line when viewed from the front. According to this structure, the cooling water 7 that has fallen onto the water permeable sheet 5 from the second drain hole 37 reaches the water retaining part 42 formed in the vertical lattice part 44 at the shortest distance from the water permeable sheet 5, and the water retaining part 42. And smoothly flows in the height direction H. The cooling water 7 flowing along the vertical lattice portion 44 flows to the water retaining portion 42 formed in the horizontal lattice portion 45 at the intersection with the horizontal lattice portion 45, and therefore the cooling water 7 is likely to evaporate or the like. Even so, the cooling water 7 can be efficiently supplied to the entire water retaining section 42.

From the viewpoint described above, it is preferable that the second drain hole 37 has an open / close control device (not shown) that can adjust the discharge amount of the cooling water 7 according to weather conditions. According to this structure, in the case of extreme heat, the opening / closing control device is opened to discharge the cooling water 7, supplying a sufficient amount of the cooling water 7 to the water permeable sheet 5 and the water retaining portion 42, and in the rain or cloudy weather. In this case, the opening / closing control device is closed to limit the discharge amount of the cooling water 7, so that the waste of the cooling water 7 can be avoided.

The cooling water 7 is supplied to the water retention unit 42 through the supply path described with reference to FIGS. 6 and 7, and the cooling water 7 is vaporized in the water retention unit 42, thereby being sucked into the intake port 12 as illustrated in FIG. 8. The outside air a1 is cooled (vaporization latent heat of the cooling water 7), and the cooled intake air a2 is supplied to the heat exchanger 11 through the intake port 12. As a result, the efficiency of heat exchange performed between the intake air a2 and the heat exchanger 11 is improved, and the power consumption of the outdoor unit body 1 accompanying the operation is reduced.

By the way, as already explained, when trying to save electricity in ordinary households, especially during summer days when power consumption dramatically increases due to cooling, it is about half of the total power consumption of home households. Because air conditioners occupy the air-conditioner, in order to efficiently achieve power saving in ordinary households, the air-conditioner must first be saved. With regard to the power-saving technology related to this type of air conditioner, conventionally, the cooling water is sprayed from the spray nozzle built in the outdoor unit body, and the heat exchanger is directly cooled, thereby improving the heat exchange efficiency in the heat exchanger. In the cooling device to be used (for example, Japanese Patent No. 4077558), in addition to the spray nozzle, the water supply line from the water storage tank to the spray nozzle, the drainage line of the sprinkled cooling water, and the spraying operation of the spray nozzle are controlled. Since a complicated watering mechanism such as a device is required, the cost increases accordingly.

In addition, the spray nozzle should be attached to the inside of the outdoor unit main body in the design stage and the manufacturing stage in advance, so that it cannot be used after the outdoor unit main body currently used. . In other words, in order to introduce the cooling device, it is necessary to buy an outdoor unit equipped with an injection nozzle instead of the outdoor unit currently used. There is a problem that it is ineffective as a power saving measure in ordinary households.

Further, a cooling device that directly cools the heat exchanger by bringing a water retaining cloth containing cooling water into contact with the heat exchanger (for example, JP 2010-216709 A), The water retaining cloth closes the air inlet and causes a problem that a necessary amount of outside air cannot be blown to the heat exchanger. Moreover, it is difficult to make the water retaining cloth uniformly contact the surface of the heat exchanger, and the cooling effect becomes unstable. Therefore, there is a problem that a stable power saving effect cannot be obtained.

Further, in a cooling device (for example, Japanese Patent Application Laid-Open No. 2004-003806), a mat member is disposed in the vicinity of a heat exchanger in the outdoor unit main body, cooling water flows down to the mat member, and the intake air is cooled. In addition to the material, a complicated cooling water supply mechanism such as a device for supplying cooling water to the mat material and a device for controlling the supply is required, which increases the cost accordingly. In addition, since the supply mechanism is to be attached to the interior of the outdoor unit in advance at the design stage and the manufacturing stage, a high-cost problem occurs, and it is not effective as a power saving measure in general households. There is a problem.

On the other hand, according to the cooling device 2 described with reference to FIGS. 1 to 8 and the air conditioner outdoor unit using the same, all the above-described problems can be solved. For example, in the cooling unit 4 constituting the cooling device 2 of FIGS. 1 to 8, a sponge-like water retaining unit 42 is attached to the base unit 41. In other words, the water retaining part 42 is supported by the base part 41. According to this configuration, from the viewpoint of cooling efficiency, the shape and dimensions of the water retaining portion 42 can be set to an optimal configuration. In addition, since the sponge-like water retention part 42 is attached to the base part 41, handling during construction work is facilitated, and construction cost can be reduced.

The cooling effect of the cooling device 2 can be explained as a result of the latent heat of vaporization of the cooling water 7 in the water retention part 42. That is, due to the configuration in which the water retaining portion 42 has the vent hole 43, when the cooling water 7 is supplied to the water retaining portion 42, the air passing through the vent hole 43 is cooled by the latent heat of vaporization of the cooling water 7.

Here, one of the features of the cooling device 2 of FIGS. 1 to 8 is the configuration of a mechanism (supply path) for supplying the cooling water 7 to the water retention unit 42. That is, as described with reference to FIGS. 6 and 7, the water storage tank 3 has the first and second drain holes 36 and 37, and the cooling water 7 is stored in the water storage tank 3. In this case, the cooling water 7 is discharged from the first and second drain holes 36, 37 to the water permeable sheet 5, dropped onto the water permeable sheet 5, and then supplied to the water holding unit 42 through the inside of the water permeable sheet 5. It will be.

As long as the cooling water 7 is stored in the water storage tank 3 without using a water pump, a complicated control device, a driving power source thereof, and the like in the supply path of the cooling water 7 described above, The cooling water 7 can be continuously supplied automatically to the water retention unit 42. Therefore, it is possible to provide the cooling device 2 that can reduce the manufacturing cost, the construction cost, and the maintenance management cost.

6 and 7, the water is supplied from the water storage tank 3 to the water retention unit 42 through the water permeable sheet 5. According to this configuration, for example, the cooling water 7 discharged from the first drain hole 36 spreads into the interior of the water permeable sheet 5 by capillary action, and then water is retained through the contact portion between the water permeable sheet 5 and the water retaining part 42. Since the water is supplied to the portion 42, a wide and uniform amount of the cooling water 7 can be supplied to the water retaining portion 42 regardless of the opening position and the number of the first drain holes 36. Accordingly, the latent heat of vaporization of the cooling water 7 in the water retaining section 42 can be generated uniformly, and as a result, an even cooling effect can be produced.

Each of the water storage tank 3, the cooling unit 4, and the water permeable sheet 5 constituting the cooling device 2 is combined with the outdoor unit main body 1 having a known basic configuration, and further constitutes the outdoor unit main body 1. Since it is attached to the outer surface (the top surface portion 13) of the housing 10, it can be retrofitted to an existing air conditioner outdoor unit. Therefore, it is possible to provide a cooling device capable of reducing the electricity bill by using the air conditioner and the outdoor unit main body in addition to the outdoor unit main body 1 that is currently used without newly replacing the air conditioner and the outdoor unit main body.

In the air conditioner outdoor unit, the cooling unit 4 of the cooling device 2 covers the air inlet 12 of the outdoor unit body 1. According to this configuration, as already described, the outside air a1 passing through the vent hole 43 is cooled in advance by the latent heat of vaporization of the cooling water 7 in the water retaining portion 42, and the cooled outside air a1 (ie, the intake air a2) is To the heat exchanger 11. As a result, the efficiency of heat exchange performed between the intake air a2 and the heat exchanger 11 is improved, and the power consumption of the outdoor unit main body 1 accompanying the operation is reduced. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling, and the air conditioner outdoor unit using the same.

Since the water permeable sheet 5 is placed on the top surface portion 13 of the outdoor unit body 1, the outdoor unit is generated by the latent heat of vaporization of the cooling water 7 generated in the water permeable sheet 5 when the cooling water 7 is supplied to the water permeable sheet 5. As a result of cooling the main body 1 as a whole, and further cooling the air inside the outdoor unit main body 1, the efficiency of heat exchange of the heat exchanger 11 is improved. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling, and the air conditioner outdoor unit using the same.

Since the water retaining part 42 is attached to the base part 41, even if the cooling part 4 is attached so as to cover the air inlet 12, the installation posture of the water retaining part 42 is stabilized by the weight and rigidity of the base part 41. As a result, for example, there is a problem that the water retaining part 42 is attracted to the intake port 12 or a problem that the sucked water retaining part 42 becomes a suction resistance and the necessary amount of intake air a2 cannot be blown to the heat exchanger 11. Does not occur. Therefore, an air conditioner outdoor unit that can reduce maintenance costs can be provided.

9 has the same configuration requirements as the air conditioner outdoor unit described with reference to FIGS. 1 to 8 except that an inclined surface is formed on the bottom 33 of the water storage tank 3. Hereinafter, the difference will be mainly described.

9, the thickness of the bottom 33 viewed in the height direction T gradually decreases from one side of the depth direction (T) to the other side. With this configuration, the bottom 33 forms an inclined surface whose inner surface is inclined from one to the other when viewed in the depth direction (T). If it demonstrates from a different viewpoint, the inner surface of the bottom part 33 will become an inclined surface where height becomes low toward the side part (34) with the 2nd drain hole 37. FIG.

As described with reference to FIG. 1 to FIG. 8, the cooling device 2 according to the present invention has the water storage tank 3 attached to the outdoor unit main body 1, and the cooling water 7 stored in the water storage tank 3 is gradually added to the water retaining portion 42. By supplying the water, the outdoor unit main body 1 and the intake air a2 are cooled by using the ancient Japanese watering principle, that is, the heat exchange phenomenon due to the latent heat of vaporization of the cooling water 7, thereby improving the heat exchange efficiency. It is characterized by reducing the operating time of the exchanger and saving electricity charges.

9 can have all the advantages described with reference to FIGS. 1 to 8. Further, according to the embodiment of FIG. 9, at the end of the operation period of the cooling device 2 determined by the amount of water stored in the cooling water 7, the cooling water 7 collects on the second drain hole 37 side according to the inclined surface of the bottom 33. Therefore, drainage (sprinkling) of the cooling water 7 performed from the second drain hole 37 can be performed over a long period of time, and the cooling water 7 stored in the limited water storage space 300 is efficiently used. can do.

10 and 11 have basically the same configuration requirements as the air conditioner outdoor unit described with reference to FIGS. 1 to 8 except that the support base 8 is provided. Hereinafter, the difference will be mainly described.

The cooling device 2 constituting the air conditioner outdoor unit of FIGS. 10 and 11 includes a support base 8, a water permeable sheet 5, a water storage tank 3, and a cooling unit 4. The water storage tank 3, the water permeable sheet 5, and the support base 8 are stacked on the top surface portion 13 of the outdoor unit body 1 in the order described above.

The support base 8 has an inclined surface 80 whose height decreases along one direction. The support 8 is placed on the top surface 13 of the upper portion of the housing 10 so that the lowest end 81 of the inclined surface 80 faces the inlet 12 side.

The water storage tank 3 is mounted on the support base 80 and the top surface portion 13 with the water permeable sheet 5 interposed therebetween so that the bottom 33 faces the water permeable sheet 5. More specifically, in the water storage tank 3, the bottom 33 is disposed on the inclined surface 80, and the side surface where the second drainage hole 37 is provided is the second drainage hole 37. It inclines so that it may become a position lower than the side part which is not provided. As shown in FIG. 11, the bottom 33 of the water storage tank 3 is inclined along the inclination angle of the inclined surface 80, and the water storage tank 3 is disposed vertically to the top surface portion 13 and the ground (not shown) as a whole. .

The support base 8 has a coupling part (82). More specifically, the support base 8 of FIGS. 10 and 11 has a pair of fitting projections 82, and the pair of fitting projections 82 is opposite to the lowest end 81 in the depth direction T. In the height direction H from the inclined surface 80. The water storage tank 3 has a concave portion corresponding to the fitting convex portion 82 at the bottom 33, and is fixed by concave and convex fitting with the fitting convex portion 82 in a state of being disposed on the inclined surface 80. According to this configuration, the water storage tank 3 can be stably placed on the inclined surface 80.

The water permeable sheet 5 is made of a porous material, and a surface region on one end side across the bent portion is disposed between the outer surface of the bottom 33 and the inclined surface 80 so as to face the first drain hole 36, The surface area on the end side is in contact with the water retention part 42. More specifically, the water permeable sheet 5 is installed on the inclined surface 80, is attached so as to hang from the lowest end 81 of the inclined surface 80 to the side surface portion 14 with the air inlet 12, and hangs down on the side surface portion 14. The inner surface of the portion overlaps with the outer surface of the water retention portion 42 and is in surface contact with the water retention portion 42 so as to be water-permeable. The surface contact portions between the water permeable sheet 5 and the water retaining portion 42 are preferably bonded to each other leaving a contact area through which water can pass.

The embodiment of FIGS. 10 and 11 is simply described by referring to FIGS. 1 to 8 because the inclined surface of the bottom 33 described with reference to FIG. 9 is separated as a separate member. Can have all the benefits.

In addition, in the air conditioner outdoor unit shown in FIGS. 10 and 11, the support base 8 is placed on the top surface portion 13 so that the lowest end 81 of the inclined surface 80 faces the inlet 12. According to this configuration, in the supply path for supplying the cooling water 7 to the water retaining portion 42, the movement of the cooling water 7 in the water permeable sheet 5 is caused by gravity based on the height difference of the inclined surface 80 in addition to the capillary phenomenon. The moving efficiency of the cooling water 7 is improved. As a result, since the cooling water 7 is smoothly supplied to the cooling unit 4 attached to the intake port 12, an air conditioner outdoor unit capable of reducing power consumption during cooling can be provided.

FIG. 12 shows an embodiment of the cooling unit 4 different from those shown in FIGS. Hereinafter, the difference will be mainly described. The cooling unit 4 in FIG. 12 is a plate-like body having a honeycomb structure. More specifically, the base portion 41 is formed by punching a plate-like body mainly composed of a metal material such as aluminum or stainless steel from the viewpoint of corrosion resistance, weather resistance, impact resistance, etc. A plurality of regular hexagonal through portions 46 (through holes) are formed in the inside as viewed from the front, and are arranged in a honeycomb shape.

The water retaining part 42 is formed with a constant thickness around the base part 41 constituting the opening edge of the through part 46, and the air holes 43 are formed in a region partitioned by the surface of the water retaining part 42. Is formed.

As described with reference to FIGS. 1 to 11, one of the features of the cooling part 4 is that the base part 41 has the through part 46, and the vent hole 43 is formed along the shape of the through part 46. Therefore, the embodiment shown in FIG. 12 can have all the advantages described with reference to FIGS. Furthermore, the cooling unit 4 of FIG. 12 has a honeycomb structure, and unlike the case of FIGS. 1 to 11, the water retaining unit 42 provided around the vent holes 43 crosses diagonally, so that the cooling unit 4 When the cooling water (7) is supplied to the upper edge in a state where 4 is suspended, the cooling water (7) smoothly flows along the height direction H and the width direction W. Therefore, it is possible to provide an air conditioner outdoor unit that can improve the cooling efficiency of the cooling unit 4 and thereby reduce power consumption during cooling.

13 and 14 show an embodiment of the cooling unit 4 different from those shown in FIGS. 1 to 12. Hereinafter, the difference will be mainly described.

13 and 14, the base portion 41 has the same structure as that described with reference to FIGS. 1 to 11. That is, the base portion 41 is a frame body having a lattice-shaped portion inside, and includes a vertical lattice portion 44 extending in the height direction H and a horizontal lattice portion 45 extending in the width direction W, and the vertical lattice portion 44. In addition, a through portion 46 penetrating in the thickness direction T is formed inside the portion surrounded by the horizontal lattice portion 45.

The water retaining portion 42 is a sheet-like body having a porous structure, and is attached to one surface of the base portion 41 viewed in the thickness direction T and covers the entire surface. In short, the cooling unit 4 has a so-called shoji-like structure in which the base portion 41 is a crosspiece and the water retaining portion 42 is a shoji paper. The ventilation hole 43 is exposed to the inside of the through part 46 partitioned in a lattice shape, and penetrates the water retaining part 42 covering the through part 46 in the thickness direction T.

As described with reference to FIGS. 1 to 12, the cooling effect of the cooling device 2 is explained as a result of the latent heat of vaporization of the cooling water 7 in the water retaining unit 42, and therefore the flow of the cooling unit 4 is not limited. The air holes 43 may have a structure that penetrates the water retaining portion 42 as an outside air passage. The embodiment shown in FIGS. 13 and 14 can have all the advantages described with reference to FIGS. Furthermore, according to the embodiment of FIGS. 13 and 14, it is only necessary to attach the sheet-like water retaining part 42 to one surface of the lattice-like base part 41, and thus the manufacturing cost can be reduced.

15 and FIG. 16 have basically the same structure as the embodiment of FIG. 10 and FIG. 11 except for the mounting position of the cooling unit 4. Hereinafter, the difference will be mainly described.

15 and 16 is attached to the outer surface of the housing 10 and covers the exhaust port 15 in the attached state. The cooling part 4 is attached to the side part 14 by a pair of latching hooks 6, 6 and covers the exhaust port 15 in the attached state. The cooling unit 4 has a structure in which only the upper edge portion of the base unit 41 is suspended by a pair of hooks 6, 6, but the mounting structure of the cooling unit 4 to the side surface unit 14 is stable, construction It can be appropriately changed from the viewpoint of efficiency and the like. This point is as described with reference to FIGS.

By the way, in this type of air conditioner, exhaust hot air is discharged from the exhaust port 15 by the heat exchange action. This exhausted hot air has an adverse effect on the environment, such as contributing to the heat island phenomenon. Moreover, the surrounding air which should be attracted | sucked by an outdoor unit with exhaust hot air is warmed, and the vicious cycle that the heat exchange efficiency of an outdoor unit falls also arises. Therefore, in order to reduce adverse effects on the environment and improve the heat exchange efficiency of the outdoor unit, it is also important to cool the exhaust hot air.

However, the conventional exhaust hot air cooling technology has not been able to meet the above requirements. For example, a cooling device (Japanese Patent Application Laid-Open No. 2004-11992) that arranges a water retaining cloth on the exhaust outlet side of the outdoor unit main body and cools the exhaust hot air causes the water retaining cloth to be held on the frame body in an unfolded state, By supplying drain water of the outdoor unit main body to the water retaining cloth from the drain pipe provided in, exhaust heat air blown to the water retaining cloth is cooled. In this configuration, since cooling water is supplied to the water retaining cloth, it is necessary to provide a space for the drain piping around the air conditioner outdoor unit. Therefore, there is a problem that the cooling device cannot be installed depending on the specific arrangement conditions of the outdoor unit. .

On the other hand, according to the cooling device 2 of FIG. 15 and FIG. 16 and the air conditioner outdoor unit using the same, the above-mentioned request can be met. For example, the cooling unit 4 constituting the cooling device 2 of FIGS. 15 and 16 covers the exhaust port 15 of the outdoor unit body 1. According to this configuration, the exhaust hot air released from the exhaust port 15 by the heat exchange action of the outdoor unit main body 1 is cooled by the latent heat of vaporization of the cooling water 7 in the water retaining portion 42 as already described when passing through the vent hole 43. Therefore, adverse effects on the environment can be reduced. Moreover, since the problem of heating the surrounding air which should be attracted | sucked to an outdoor unit by exhaust hot air is avoided by cooling exhaust hot air, the power consumption of the outdoor unit main body 1 accompanying the operation is reduced. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling, and the air conditioner outdoor unit using the same.

15 and FIG. 16 has all the basic configurations of the cooling device 2 of FIGS. 1 to 11, and therefore can achieve the same operational effects. For example, in the cooling device 2 of FIGS. 15 and 16, when the cooling water 7 is stored in the water storage tank 3 that is the starting point of the supply path, the cooling water 7 is permeable to the permeable sheet from the first drain hole 36 by gravity or the like. 5 is discharged. The discharged cooling water 7 permeates the inside of the water-permeable sheet 5 radially by the so-called capillary phenomenon with the first drain hole 36 as the center. A part of the cooling water 7 soaked into the water permeable sheet 5 is further supplied to the water retaining part 42 through a contact portion between the water permeable sheet 5 and the water retaining part 42 (see FIG. 17).

According to the above-described structure, the cooling water 7 discharged from the first drain hole 36 penetrates the interior of the water permeable sheet 5 over a wide area, and then passes through the contact portion between the water permeable sheet 5 and the water retaining part 42 to the water retaining part 42. Since the water is supplied, the cooling water 7 is supplied widely and uniformly to the water retaining portion 42 regardless of the opening position and the number of the first drain holes 36. Accordingly, the latent heat of vaporization of the cooling water 7 in the water retaining section 42 can be generated uniformly, and as a result, an even cooling effect can be produced.

In addition, in the air conditioner outdoor unit shown in FIGS. 15 and 16, the support base 8 is placed on the top surface portion 13 so that the lowest end 81 of the inclined surface 80 faces the exhaust port 15. According to this configuration, in the supply path for supplying the cooling water 7 to the water retaining part 42, the movement of the cooling water 7 in the water permeable sheet 5 is caused by gravity based on the height difference of the inclined surface 80 in addition to the capillary phenomenon. The moving efficiency of the cooling water 7 is improved. As a result, since the cooling water 7 is smoothly supplied to the cooling unit 4 attached to the exhaust port 15, it is possible to provide an air conditioner outdoor unit that can reduce power consumption during cooling.

On the other hand, the water storage tank 3 has a second drain hole 37, and the cooling water 7 is also discharged from the second drain hole 37 to the water permeable sheet 5. The cooling water 7 that has fallen onto the water permeable sheet 5 from the second drain hole 37 passes through the inside of the water permeable sheet 5 and is supplied to the water retaining part 42 through the contact portion between the water permeable sheet 5 and the water retaining part 42. (See FIG. 18).

As described above, in the cooling device 2 of FIGS. 15 to 18, the cooling effect of the cooling unit 4 is automatically and continuously exhibited as long as the cooling water 7 is discharged from the first water tank 3. The ambient air to be sucked into the outdoor unit main body 1 is automatically and continuously cooled. As a result, the efficiency of heat exchange performed between the intake air and the heat exchanger is improved, and the power consumption of the outdoor unit main body 1 accompanying the operation is reduced. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling.

Furthermore, since each of the water storage tank 3, the cooling unit 4, and the water permeable sheet 5 constituting the cooling device 2 is attached to the outer surface of the housing 10 of the outdoor unit main body 1, the portion to which the cooling device 2 is attached. That is, the direct sunlight on the top surface portion 13 of the outdoor unit main body 1 and the side surface portion 14 on the exhaust port 15 side is blocked, and an increase in temperature inside the outdoor unit main body 1 is suppressed. Therefore, the heat exchange efficiency of the outdoor unit can be improved.

Since the water retaining part 42 is attached to the base part 41, even if the cooling part 4 is attached so as to cover the exhaust port 15, the installation posture of the water retaining part 42 is stabilized by the weight and rigidity of the base part 41. As a result, for example, the problem that the water retaining part 42 blocks the exhaust port 15 does not occur. Therefore, an air conditioner outdoor unit that can reduce maintenance costs can be provided.

Further, through the supply path described with reference to FIGS. 6 and 7, the cooling water 7 from the water storage tank 3 is supplied to the water retention unit 42, and the cooling water 7 is vaporized in the water retention unit 42, thereby Since the released high-temperature air (exhaust hot air) is cooled, adverse effects on the environment can be reduced. Moreover, since the problem of heating the surrounding air which should be attracted | sucked to an outdoor unit by exhaust hot air is avoided by cooling exhaust hot air, the power consumption of the outdoor unit main body 1 accompanying the operation is reduced. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling, and the air conditioner outdoor unit using the same.

The support base 8 constituting the cooling device 2 has an inclined surface 80 whose height decreases along one direction, the water tank 3 is disposed on the inclined surface 80, and the water permeable sheet 5 is a bottom portion of the water tank 3. 33 is disposed between the outer surface and the inclined surface 80. According to this configuration, in the supply path for supplying the cooling water 7 to the water retention part 42, gravity based on the height difference of the inclined surface 80 acts on the movement of the cooling water 7 in the water permeable sheet 5 in addition to the capillary phenomenon. The moving efficiency of the cooling water 7 is improved. As a result, since the cooling water 7 is smoothly supplied to the cooling unit 4, it is possible to provide the air conditioner outdoor unit cooling device 2 that can reduce power consumption during cooling.

Since each of the water storage tank 3, the cooling unit 4, and the water permeable sheet 5 constituting the cooling device 2 is attached to the outer surface of the housing 10 of the outdoor unit main body 1, a portion to which the cooling device 2 is attached, that is, Direct sunlight to the top surface portion 13 of the outdoor unit main body 1 and the side surface portion 14 on the exhaust port 15 side is blocked, and an increase in temperature inside the outdoor unit main body 1 is suppressed. Therefore, the heat exchange efficiency of the outdoor unit can be improved.

FIG. 19 shows an attachment mode of the cooling unit 4 different from those shown in FIGS. Hereinafter, the difference will be mainly described.

In the embodiment of FIG. 19, the cooling unit 4 has both side edge portions in the height direction H and both side edge portions in the width direction W by the adhesive tape 61 on the side surface portion 14 on the exhaust port 15 side of the outdoor unit body 1. Is pasted. That is, the adhesive tape 61 of FIG. 19 has an adhesive surface on one surface, and the cooling surface 4 is attached to the side surface portion 14 by the adhesive surface contacting the cooling portion 4 and the side surface portion 14 in this order.

19 can have all the advantages described with reference to FIGS. 1 to 18. Furthermore, according to the embodiment of FIG. 19, since the cooling unit 4 is in direct contact with the side surface unit 14, when the cooling water is supplied to the cooling unit 4, the outdoor unit is generated by the latent heat of vaporization generated in the cooling unit 4. The main body 1 is cooled as a whole, and the efficiency of heat exchange of the heat exchanger 11 is improved. Therefore, it is possible to provide the cooling device 2 capable of reducing the power consumption during cooling, and the air conditioner outdoor unit using the same.

Further, unlike the embodiment shown in FIGS. 1 to 18, the embodiment shown in FIG. 19 can reduce the manufacturing cost by the amount that the hook 6 is unnecessary. However, from the viewpoint of manufacturing cost, the adhesive tape 61 may have an adhesive surface on both front and back surfaces. When the adhesive tape 61 having adhesive surfaces on both front and back sides is used, unlike the embodiment of FIG. 19, the cooling unit 4 is attached to the side surface part 14 with the adhesive tape 61 interposed therebetween.

20 and 21 show an arrangement mode of the cooling unit 4 different from those shown in FIGS. 1 to 19. That is, as already described, since this type of outdoor unit is usually arranged with the side surface on the inlet side facing the wall surface 9 of the house, the outdoor unit main body 1 and the house facing this In many cases, there is no sufficient gap between the wall surface 9 and the cooling device cannot be installed depending on the specific arrangement conditions of the outdoor unit body.

20 and 21 show an embodiment for solving the above-described problem. Hereinafter, the difference will be mainly described. In the embodiment of FIG. 20, the cooling unit 4 has two bent portions 47 that are continuous in the height direction H, and has a three-surface structure partitioned by the bent portions 47. If it demonstrates simply, the cooling part 4 will be U shape seeing from the plane, Comprising: The both ends which comprise an open side face the wall surface of a house, and are attached to the circumference | surroundings of the outdoor unit main body 1. FIG.

On the other hand, in the embodiment of FIG. 21, the cooling unit 4 has four bent portions 47 that are continuous in the height direction H, and has a four-surface structure partitioned by the bent portions 47. If it demonstrates simply, the cooling part 4 will be a square cylinder shape seen from the plane, and is attached so that the outer periphery of the outdoor unit main body 1 may be enclosed.

Although not necessarily clear from FIGS. 20 and 21, the cooling unit 4 may be attached to the side surface of the outdoor unit main body 1 with, for example, the adhesive tape 61 of FIG. It may be erected on the ground.

20 and 21 may have all the advantages described with reference to FIGS. 1 to 19. For example, since the cooling unit 4 in FIGS. 20 and 21 is arranged so as to surround the outdoor unit main body 1, it should cool the exhaust hot air discharged from the exhaust port 15 and be sucked into the outdoor unit main body 1. The surrounding air can be efficiently cooled. Similarly, the light shielding effect of the cooling unit 4 against direct sunlight is also improved.

Furthermore, according to the embodiment of FIG. 20, the cooling unit 4 has a U-shape when viewed from the plane, and both ends constituting the open side face the wall surface 9 of the house, so that the periphery of the outdoor unit body 1 is Therefore, the cooling device 2 can be installed even when there is not a sufficient gap between the outdoor unit main body 1 and the wall surface 9 of the house facing the outdoor unit main body 1.

21 can stand up on the ground around the outdoor unit main body 1, there is a sufficient gap between the outdoor unit main body 1 and the wall surface 9 of the house facing the outdoor unit main body 1. Even if it is not, the cooling device 2 can be installed.

The cooling device 2 in FIGS. 22 and 23 has basically the same structure as the embodiment in FIGS. 1 and 8 except that the second water tank 9 is included. Hereinafter, the difference will be mainly described.

The second water tank 9 has a second water storage space 920, is disposed at a place other than the top surface portion 13 of the outdoor unit body 1, and is connected to the first water tank 3 in a water-permeable manner. The second water storage tank 9 of FIGS. 22 and 23 has an outer tank portion 91, an inner tank portion 92, a lid portion 93, and a water pipe 95, and is disposed on the installation surface on the side of the outdoor unit main body. Has been.

The outer tank portion 91 is a housing portion of the second water storage tank 9 and has an opening 97 on the upper side when viewed in the height direction H. The opening 97 opens the internal space of the outer tub 91 to the outside. The lid 93 is detachably attached to the opening 97.

The inner tank portion 92 has a second water storage space 920 for storing cooling water therein, is guided to the inside of the outer tank portion 91 through the opening 97, and is stored in the outer tank portion 91 so as to be able to be taken in and out. 22 and 23, the inner tank portion 92 has a structure similar to that of a fuel tank for an oil stove, and has a water supply port 94 with a built-in on-off valve (not shown) on the bottom surface side. On the other hand, in the outer tub 91, a receiving port 96 for receiving the water supply port 94 is detachably fitted in a portion corresponding to the water supply port 94 of the inner tub portion 92. The receiving port 96 is provided with an operation pin (not shown) that pushes up an on-off valve built in the water supply port 94 at the center.

The water distribution pipe 95 is for supplying the cooling water stored in the second water storage space 920 to the outside, and is connected to the receiving port 96. The water distribution pipe 95 connects the second water storage space 920 and the water storage space (300) of the first water storage tank 3 in a water-permeable manner. That is, the 1st water storage tank 3 and the 2nd water storage tank 9 are connected by water distribution pipe 95, and comprise the large capacity | capacitance water storage tank (3, 9) which continues integrally.

When the inner tank portion 92 is stored in the outer tank portion 91, the water supply port 94 is inserted into the receiving port 96. An operation pin protrudes from the receiving port 96, and the opening / closing valve of the water supply port 94 is pushed up, so that the water supply port 94 is opened, and the cooling water in the second water storage space 920 passes through the reception port 96, Further, the water is sent out to the first water tank 3 through the water distribution pipe 95.

The water supply port 94 may be either fixed or detachable with respect to the receiving port 96. Moreover, when the 2nd water tank 9 is attached to a position lower than the 1st water tank 3 as shown in FIG.22 and FIG.23, the 2nd water tank 9 is the 2nd water storage by a water pump (not shown). Cooling water in the space 920 is supplied to the first water storage space 300. As the water supply pump, a well-known water supply system of this type can be used.

The cooling device 2 of FIGS. 22 and 23 is characterized by having a second water storage tank in addition to the basic configuration related to the cooling effect of FIGS. 1 to 8 and the basic configuration related to the cooling water supply path. There is one. That is, conventionally, in this type of cooling device, since the duration of the cooling effect is proportional to the amount of cooling water stored, it is necessary to increase the capacity of the water storage tank (3). In the configuration provided only on the top surface portion 13 of the main body 1, it is difficult to secure a sufficient installation space, and there arises a problem that it is not possible to meet the demand for a large capacity of the water storage tank (3).

Also, this type of outdoor unit body 1 tends to be installed in a narrow space such as an alley part with a neighboring house or a corner of a veranda in order to secure a living space. As a result, it is not possible to secure a space enough to install a large-capacity water tank (3) on the top surface portion 13 in the first place. In particular, when the outdoor unit main body 1 is hung on the outer wall surface of a building, a large-capacity water tank (3) should be installed on the top surface 13 from the viewpoint of preventing a fall accident due to an earthquake or a typhoon. The problem of not being able to occur.

In order to solve the problem related to the increase in the capacity of the water storage tank described above, the cooling device 2 of FIGS. 22 and 23 has a second water storage tank 9. The 2nd water tank 9 has the 2nd water storage space 94, is arrange | positioned in places other than the top | upper surface part 13, and is connected with the 1st water tank 3 in water flow. According to this configuration, the total amount of the cooling water 7 can be increased by the capacity of the second water storage space 94. As a result, even when there is not enough space to install a large-capacity water storage tank (3) on the top surface portion 13, it is possible to meet the demand for increasing the capacity of the water storage tank.

Moreover, by having the 2nd water tank 9 arrange | positioned in places other than the top | upper surface part 13, the total amount of the cooling water 7 can be increased in the state which maintained the capacity | capacitance of the 1st water tank 3, or 2nd water storage space. The first water tank 3 can be reduced in size by the capacity of 94. Therefore, it is possible to provide a rejection device that can avoid a fall accident due to an earthquake or a typhoon and can be safely installed in a narrow place.

Each of the first water storage tank 3, the cooling unit 4, and the water permeable sheet 5 constituting the cooling device 2 is combined with the outdoor unit main body 1 having a known basic configuration, and the outdoor unit main body 1 is Since it is attached to the outer surface (top surface part 13) of the housing 10 to comprise, it can be used retrofitting to an existing air conditioner outdoor unit. Therefore, it is possible to provide a cooling device capable of reducing the electricity bill by using the air conditioner and the outdoor unit main body in addition to the outdoor unit main body 1 that is currently used without newly replacing the air conditioner and the outdoor unit main body.

The embodiment of FIGS. 24 and 25 has basically the same structure as that of the embodiment of FIGS. 22 to 23 except that the support base 8 is included, and will be described with reference to FIGS. 22 to 23. Have all the benefits. Further, the cooling device 2 of FIGS. 24 and 25 has a support base 80, so that a capillary tube is provided for the movement of the cooling water 7 in the water permeable sheet 5 in the supply path for supplying the cooling water 7 to the water retaining portion 42. In addition to the phenomenon, gravity based on the height difference of the inclined surface 80 works, so that the moving efficiency of the cooling water 7 is improved. As a result, since the cooling water 7 is smoothly supplied to the cooling unit 4, it is possible to more efficiently achieve a reduction in power consumption during cooling.

The cooling device 2 of FIGS. 26 and 27 has basically the same structure as the embodiment of FIGS. 15 and 18 except that the second water storage tank 9 is included, so refer to FIGS. 15 and 18. All the advantages described above. Further, the cooling device 2 of FIGS. 26 and 27 includes the second water storage tank 9, so that the cooling water 7 is equivalent to the capacity of the second water storage space 94 as described with reference to FIGS. 22 to 23. The total amount can be increased. As a result, even when there is not enough space to install a large-capacity water storage tank (3) on the top surface portion 13, it is possible to meet the demand for increasing the capacity of the water storage tank.

Moreover, by having the 2nd water tank 9 arrange | positioned in places other than the top | upper surface part 13, the total amount of the cooling water 7 can be increased in the state which maintained the capacity | capacitance of the 1st water tank 3, or 2nd water storage space. The first water tank 3 can be reduced in size by the capacity of 94. Therefore, it is possible to provide a rejection device that can avoid a fall accident due to an earthquake or a typhoon and can be safely installed in a narrow place.

Although the contents of the present invention have been specifically described above with reference to the preferred embodiments, it is obvious that those skilled in the art can take various modifications based on the basic technical idea and teachings of the present invention. It is. For example, in the embodiment of FIGS. 13 and 14, the water retaining portions 42 may be provided on both surfaces of the base portion 41 as viewed in the thickness direction T, and the opening shape and the diameter of the vent holes 43 are appropriately adjusted while considering the air flow rate. can do.

Further, the cooling device 2 according to the present invention is characterized by a supply path for supplying the cooling water 7 from the bottom 33 of the water storage tank 3 to the water holding part 42 through the water permeable sheet 5. Therefore, when the bottom 33 of the water storage tank 3 of FIG. 3 is made of a material having water permeability such as a water permeable ceramic, the cooling water 7 can be supplied to the water permeable sheet 5 from the entire surface of the bottom 33. In the above configuration, it should be considered that the first drainage holes 36 are not present, but countless first drainage holes 36 are present inside the water-permeable ceramic constituting the bottom 33.

Furthermore, as described with reference to FIGS. 1 to 14, the main function of the base portion 41 is to support the water retaining portion 42 and to form the through portion 46 that is the basis of the vent hole 43. It is important that the penetrating portion 46 penetrates from one surface to the other surface. For example, the opening shape of the penetrating portion 46 can be appropriately set from the viewpoint of air permeability, cooling efficiency, processing cost, and the like. In other words, the term “lattice” that expresses the structure of the base portion 41 is not necessarily limited to the “grid shape”, and is widely used as “a bar-shaped member that intersects in two or more directions”. I would like to remind you that it should be interpreted as “a structure constructed by combination”.

26 and 27, the support base 80 may not be included. In the embodiment of FIGS. 26 and 27, even when the support base 80 is not provided, the cooling water 7 is efficiently supplied to the cooling unit 4 according to the supply path described with reference to FIGS. 1 to 7. It is clear that can be supplied.
