Description

  The present invention relates to a fluid cooling device that cools or heats a fluid stored in a container. In this specification, the fluidized material refers to a material having fluidity in at least a part of a temperature range from a high temperature at the start of cooling to a low temperature at the end of cooling, and at the end of cooling, a soup shape having a low viscosity. From what has become a gel-like thing with high viscosity.

  For example, fluid cooked foods such as soup, noodle soup, curry, meat sauce, Happo vegetables, and beverages produced in food factories and school lunch centers are cooled quickly after production to prevent bacterial growth. There is a need. Conventionally, a vacuum cooling device, a differential pressure cooling device, or the like is used as a cooling device for that purpose. However, these devices are all expensive. In the vacuum cooling device, there is a problem that the food component is reduced due to the evaporation of food components and the taste changes, and in the differential pressure cooling device, the cooling time is long. On the other hand, as a device that can be configured at low cost, there is a jacket-type cooling device that allows a cooling fluid such as cold water to flow outside the container and exchanges heat with the fluid in the inside through the container.

  As such a jacket type cooling device, for example, a hopper of a hopper member and a cover body are double combined to form a sealed cylindrical space, and at least one of the outer wall surface of the hopper or the inner wall surface of the cover body. A plurality of shielding wings that form a maze state escape path are provided so as to be positioned in the circumferential direction of the cylindrical space, and the cooling water is poured into the cylindrical space through the introduction path provided in the hopper member. The cooling water that has flowed into the hopper is diffused by the shielding wings and guided to the exit of the hopper member through the escape path, so that foods such as soups, fruit drinks, and fluids in the hopper are evenly and entirely. A fluid circulation device for cooling is known (see Patent Document 1).

JP 2008-029276 A

  However, in the cooling method in which the cooling medium is guided only to the outside of the hopper as described above, the fluid is in contact with only the inner wall of the hopper, and heat exchange between the fluid and the cooling medium is performed through the inner wall. For this reason, there is only a cooling capacity corresponding to the surface area of the inner wall, and there is a problem that heat transfer efficiency is poor. Such a problem is naturally the same when a heating medium such as a high-temperature liquid or gas is used instead of the cooling medium.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a fluid cooling device having high heat transfer efficiency.

  In order to solve the above-described problems, one embodiment of the present invention is a fluid cooling device that cools or heats a fluid stored in a container, and performs heat exchange with the fluid inside. A cooling section that is formed by bending a conduit through which a heat exchange medium flows along a surface of a predetermined shape, and that cools or heats the fluidized material by contacting the fluidized material on an outer periphery of the conduit; and the conduit An introduction pipe for introducing the heat exchange medium into the pipe, and a lead-out pipe for extracting the heat exchange medium from the conduit.

  According to the present invention, a fluid cooling device having high heat transfer efficiency can be realized. The other effects of the present invention will be described in the section for carrying out the invention below.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In the present embodiment, the fluid cooling device is a fluid cooling device in which a cooling medium is passed through a conduit and heat exchange is performed between the fluid and the cooling medium (heat exchange medium) via the conduit. An explanation will be given taking the apparatus as an example. Hereinafter, the details of the fluid cooling device according to the present embodiment will be described with reference to the drawings. First, the structure of the fluid cooling device according to the present embodiment will be described with reference to FIGS. As shown in FIGS. 1 and 2, the fluid cooling device 1 includes a container (dimension cylinder) 10 provided with at least two handles 102 in which the fluid is accommodated, and an inner periphery of the container 10. The cooling unit 20 having the cooling pipe 202 for cooling the fluidized material, the cooling medium supply pipe 22 for introducing a cooling medium such as water or antifreeze into the cooling unit 20, and the cooling unit 20. A cooling medium discharge pipe 24 that discharges the introduced cooling medium, and a flange 26 that is detachable from the container 10 that supports the cooling medium supply pipe 22 and the cooling medium discharge pipe 24 are configured. In FIG. 2, only the container 10, the handle 102, and the cooling pipe 202 are shown for easy understanding.

  The cooling unit 20 is a cylindrical member disposed so as to be immersed in a fluid filled in the container 10, and as shown in FIG. 1, four flexible cooling units through which a cooling medium flows are provided. The peripheral walls are formed by the pipes 202a to 202d (hereinafter referred to as the cooling pipe 202 if they are not individually distinguished). The cooling pipe 202 is a conduit having a circular cross section made of a heat transfer member such as a metal such as stainless steel, titanium, copper, or aluminum, or an alloy. The cooling pipe 202 has a predetermined surface, in this embodiment, a cylindrical surface. It is bent along. In other words, the cylindrical shape of the cooling unit 20 is constructed by bending the cooling pipe 202. More specifically, in a state where a plurality of cooling pipes 202 are arranged in parallel so as to be spaced apart from each other by a predetermined interval (for example, 5 mm) on a substantially flat surface, the cooling pipes 202 are spirally wound together while maintaining this parallel state. . Therefore, the cooling pipe 202 adjacent to the up-down direction is a cooling pipe 202 different from itself. For example, the cooling pipe 202a is interposed between the cooling pipes 202b to 202d as shown in FIGS. It will be arrange | positioned at equal intervals in the up-down direction. The same applies to the other cooling pipes 202b to 202d.

  Note that the interval between the cooling pipes 202 described above can be set as appropriate depending on how the cooling pipes 202 are wound, and may be adjusted according to the type of fluid or the cooling medium, the required cooling capacity, or the like. Further, from the viewpoint of cooling efficiency, it is preferable that the cooling unit 20 is disposed at a predetermined interval from the inner wall of the container 10.

  The cooling pipe 202 is provided with an introduction pipe 204 for introducing a cooling medium. More specifically, the cooling pipe 202a is provided with an introduction pipe 204a, the cooling pipe 202b is provided with an introduction pipe 204b, the cooling pipe 202c is provided with an introduction pipe 204c, and the cooling pipe 202d is provided with an introduction pipe 204d. . Similarly, the cooling pipe 202 is provided with a lead-out pipe 206 for leading the cooling medium. More specifically, the cooling pipe 202a is provided with the outlet pipe 206a, the cooling pipe 202b is provided with the outlet pipe 206b, the cooling pipe 202c is provided with the outlet pipe 206c, and the cooling pipe 202d is provided with the outlet pipe 206d. .

  The introduction pipe 204 is disposed on the radially inner side of the cooling unit 20 with respect to the cooling pipe 202, and has one end connected to the cooling medium supply pipe 22 and the other end positioned at the lower end of the cooling unit 20. It is connected to the cooling pipe 202. The lead-out pipe 206 is disposed on the inner side in the radial direction of the cooling unit 20 with respect to the cooling pipe 202, and has one end connected to the cooling medium discharge pipe 24 and the other end positioned at the upper end of the cooling unit 20. It is connected to the cooling pipe 202. Therefore, the cooling medium supplied to the cooling medium supply pipe 22 is diverted by the introduction pipes 204 and supplied to the respective cooling pipes 202 positioned at the lower end of the cooling unit 20, and the cooling medium spirals from below to above. It will flow. Further, the cooling medium that has flowed upward is supplied from the respective cooling pipes 202 to the outlet pipe 206, joins in the cooling medium discharge pipe 24, and is discharged to the outside. The introduction pipe 204 and the lead-out pipe 206 are preferably composed of the same member as the cooling pipe 202.

  According to such a cooling unit 20, in order to come into contact with the fluidized material over the entire circumference of the cooling pipe 202, for example, compared to the case where the cooling medium is arranged on the outer periphery of the container containing the fluidized material and cooled, The surface area of the cooling unit 20 in contact with the fluid is extremely large, and the cooling efficiency can be significantly improved.

  In the present embodiment, the same conduit is used for the cooling pipe 202, the introduction pipe 204, and the outlet pipe 206. As shown in FIGS. 3A and 3B, these conduits have a so-called bellows shape in which a trough 208a and a crest 208b projecting radially outward from the trough 208a are continuously formed. There is no. As a result, the cooling pipe 202, the introduction pipe 204, and the discharge pipe 206 have flexibility, and can increase the surface area, thereby further improving the cooling efficiency. In addition, the shape of these conduits is not limited to this. For example, a conduit having a flat surface on which the valleys 208a and the peaks 208b are not formed as shown in FIG. 3C may be used, but a semicircular or rectangular convex portion is provided on the outer surface, etc. It is preferable to use a conduit having a shape capable of expanding the surface area of each conduit. Different types of conduits may be used for the cooling pipe 202, the introduction pipe 204, and the outlet pipe 206, respectively. In addition, the code | symbol B shown by FIG.3 (b) has shown the cavity in a conduit | pipe, ie, the flow path through which a cooling medium flows.

  The cooling medium supply pipe 22 and the cooling medium discharge pipe 24 are both L-shaped conduits with one end protruding upward, and an end 222 protruding above the cooling medium supply pipe 22 supplies the cooling medium. The end 242 projecting upward from the cooling medium discharge pipe 24 is connected to various devices and containers for cooling, storing, or discarding the discharged cooling medium again. As a result, circulation of the cooling medium of the cooling unit 20 is realized.

  As shown in FIGS. 1 and 4, a cooling medium supply pipe 22 and a cooling medium discharge pipe 24 are supported on the upper edge of the container 10, and the outer periphery of the container 10 protrudes radially outward from the container 10. A collar portion 26, which is a flat plate member, is detachably provided. Therefore, the connection between the end portion 222 of the cooling medium supply pipe 22 and the end portion 242 of the cooling medium discharge pipe 24 described above is released, and the flange portion 26 is removed from the container 10, whereby the cooling section 20 is connected to the container via each conduit. 10 can be removed easily. As a method of fixing the collar part 26 to the container 10, there are appropriate methods such as a method in which a concave part is provided on one side and a convex part is provided on the other side and these are fitted, or a method of fastening with a screw. Any method is possible. In addition, the code | symbol C shown by FIG. 4 has shown the accommodation space in which a fluid state is accommodated.

  In addition, it is preferable to fix the cooling unit 20 to the container 10 so that the cylindrical shape formed by the cooling pipe 202 does not collapse. In the present embodiment, holding plates 30 are provided at four locations in the container 10 so as to oppose each other so that the cooling unit 20 is sandwiched between the container 10 and fixed so that the cooling unit 20 is pressed against the container 10. Yes. As shown in FIG. 1, the holding plate 30 is a rectangular plate-like member extending in the vertical direction, and its upper end is fixed to the container 10 by a fixing tool 302 made of a bolt and a nut, and its lower end is the cooling unit 20. Between the cooling pipe 202a located at the lower end of the container 10 and the bottom wall of the container 10. Thus, if the cooling unit 20 is pressed against the container 10 by the holding plate 30 fixed by the simple fixing tool 302, the cooling unit 20 can be easily attached to and detached from the container 10.

  When the fluid cooling device 1 is actually used, the fluid can be cooled only by flowing the cooling medium to the cooling medium supply pipe 22 after filling the container 10 with the fluid. Here, as shown in FIG. 5, the fluid cooling device 1 further includes a cooler 40 configured in a cylindrical shape that can be accommodated in the container 10. Movement and rotation in the direction may be performed. Thereby, it can stir with cooling and the cooling efficiency becomes higher. The cooler 40 includes a hollow cylindrical main body 402 immersed in a fluid, an introduction pipe 404 for injecting a cooling medium into the main body 402, a discharge pipe 406 for discharging the cooling medium from the main body 402, and the main body 402. And a connecting portion 408 for connecting the main body 402 to a driving device (not shown) to be displaced. In addition, about the specific structure and operation | movement of this cooler 40, it is the same as that of the technique as described in "Japanese Patent Application No. 2013-273368" for which Ryohyo Industrial Co., Ltd. which is the patent applicant of this invention applied previously. Therefore, the description here is omitted.

  According to the present embodiment, since the cooling pipe 202 is bent into a cylindrical shape to form the cooling unit 20, the surface of the cooling pipe 202 is uniformly in contact with the fluidized material, so that the cooling efficiency is very high, that is, high. It becomes possible to realize heat transfer efficiency, and in turn, the cooling time can be shortened. In addition, by forming the cooling unit 20 using the bellows-like cooling pipe 202, the surface area can be enlarged, and higher cooling efficiency can be realized. Further, since the cooling unit 20 is formed by the plurality of cooling pipes 202, the heat exchange time generated between the cooling medium and the fluidized material is compared with the case where the cooling unit 20 is formed by one cooling pipe 202. And the cooling efficiency can be further increased. Further, since a gap is formed between the cooling pipes 202, the fluidity of the fluidized material is enhanced, and there is a specific effect that the temperature unevenness of the fluidized material hardly occurs. Furthermore, since the cooling unit 20 is formed only by the bent cooling pipe 202, the cost is extremely low.

  In the present embodiment, the cooling pipe 202 having a circular cross section has been described. However, the present invention is not limited to this, and an elliptical or polygonal conduit may be used. The same applies to the introduction pipe 204 and the outlet pipe 206.

  In the present embodiment, it has been described that the cooling pipe 202 of the cooling unit 20 is wound and disposed so as to draw a spiral together while maintaining a parallel state, but is not limited thereto. . For example, as shown in FIG. 6, after the cooling pipe 202a is continuously wound, the cooling pipe 202b is continuously wound so as to be concentric with the cooling pipe 202a, and the same is applied to the cooling pipes 202c and 202d. The cooling part 20a may be formed. Even in such a form, the cooling capacity similar to that of the cooling unit 20 can be provided.

  In addition, as a method of forming the cooling unit 20, a plurality of cooling pipes 202 arranged in parallel so as to be spaced apart from each other on a substantially flat surface, for example, are arranged so as to make a round while meandering vertically along the surface of a cylinder. The cooling unit 20 may be formed by being provided. Further, for example, the hollow cylinder may be formed by twisting together four cooling pipes 202 in a state where the lower end portion connected to the introduction pipe 204 is arranged in four directions of the circle.

  In addition, as shown in FIG. 7, a cooling part with a small diameter is formed by a cooling pipe 202 e and this is used as a main body 502, and a cooler 50 including the main body 502 is realized and used together with the cooling part 20. May be. That is, two cooling units 20 are prepared, the diameter of one cooling unit 20 is made smaller than the diameter of the other cooling unit 20, this one cooling unit 20 is used as a cooler 50, and the other cooling unit 20 is In the state provided along the inner periphery of the container 10, the cooler 50 is inserted into the hollow of the cylinder formed by the other cooling unit 20 to cool the fluid. According to this, since the fluid can pass through the gap between the cooling pipes 202e during the stirring operation of the fluid, the temperature unevenness can be further suppressed as compared with the cooler 40 as shown in FIG. , Cooling efficiency can be increased. Although the main body 502 shown in FIG. 7 is formed by a single cooling pipe 202e, it goes without saying that it may be formed by a plurality of cooling pipes 202 in the same manner as the cooling section 20 shown in FIG. .

  Moreover, in this Embodiment, although the cooling parts 20 and 20a and the cooler 50 were each demonstrated as a hollow cylindrical shape, it is not limited to this, A polygon and a cone may be sufficient, The shape is suitably It is. In addition, the cooling units 20 and 20a and the cooler 50 may have a so-called multiple structure in which small-diameter cooling units 20 and 20a and coolers 50 having different diameters are arranged in the hollow. By using a multiple structure, the cooling efficiency can be remarkably improved.

  In the present embodiment, the fluid cooling device 1 is described as an example of the fluid cooling device 1 in which a cooling medium flows as a heat exchange medium in the cooling pipe 202, but is not limited thereto. Absent. The fluid cooling device 1 is used as a fluid heating device that heats the fluid by flowing a heating medium that is a fluid such as a high-temperature liquid or gas into the cooling tube 202, that is, by using the cooling tube 202 as a heating tube. It is also possible to construct. Also in this case, like the fluid cooling device 1, since the area of the heating tube in contact with the fluid is extremely large, high heating efficiency, in other words, high heat transfer efficiency can be realized, and the fluid is heated in a short time. be able to.

  The present invention can be implemented in various other forms without departing from the gist or main features thereof. Therefore, the above-mentioned embodiment is only an illustration in all points, and should not be interpreted limitedly. The scope of the present invention is shown by the scope of claims, and is not restricted by the text of the specification.
