Description

   Double-cycle air-cooling system based on water-cooled air conditioner and water-cooled air-conditioning fan   

The present invention relates to the technical field of air-conditioning fans, and in particular to a dual-cycle air-cooling system based on water-cooled air conditioners and water-cooled air-conditioning fans thereof.

The prior art water-cooled air-conditioning fan includes a housing, a fan assembly, a water tank, a water pump assembly, and a water evaporation carrier. The water evaporation carrier is located inside the air inlet of the shell, and the water is stored in the water tank and the water pump assembly is used to supply water for the shower. The fan assembly drives the air to penetrate the water evaporation carrier to promote water vaporization at normal temperature, and the water evaporates, absorbs and vaporizes. The heat causes the self and the ambient air to cool down and humidify. The water that has not been evaporated and vaporized then flows back to the water tank for recycling. The humidified and cooled air is blown out from the air outlet of the casing through the air duct, which makes people feel comfortable and cool.

Obviously, the described embodiments are a part of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1, it is a schematic structural view of a front view of a water-cooled air-conditioning fan with a dual-cycle system provided in the present invention. The dual-cycle system includes a first water-cooling system 1, a second water-cooling system 2, and a fan assembly 3. The water cooling system 1 and the second water cooling system 2 are respectively arranged at the air inlet 31 and the air outlet 32 of the fan assembly 3. The natural wind 1A generated by the fan assembly 3 flows through the first water cooling system 1 at the air inlet 31 to form a primary cooling air. 1B, the primary cooling air 1B flows through the second water cooling system 2 located at the air outlet 32 to form a secondary cooling air 2A and is discharged. After the same natural wind is cooled twice by the first water cooling system 1 and the second water cooling system 2 in sequence, the cooling effect is fast, which is suitable for indoor cooling in hot summer.

Example 1

As shown in FIGS. 1, 2 and 3, the first water cooling system 1 includes a circulating water pump 11, a water tank 12, a water storage tank 13, and a water evaporation carrier 14 located at the air inlet 31 of the fan assembly 3; the water tank 12 is located at the water Below the evaporation carrier 14, the water inlet of the circulating water pump 11 communicates with the water tank 12. The circulating water pump 11 communicates with the water storage tank 13 located above the water evaporation carrier 14 through the upper water pipe 4, and the bottom of the water storage tank 13 communicates with the water evaporation carrier 14.

The water evaporation carrier 14 here has a honeycomb structure, and its material has good water absorption performance. There are numerous ventilation holes distributed throughout the water evaporation carrier. When the fan assembly is started, the air located outside the water evaporation carrier passes through the fan assembly 3. The action forms natural wind, and penetrates the ventilation holes on the water evaporation carrier to form a primary cooling wind. The natural wind refers to an unheated or cooled air stream.

The second water-cooling system 2 is a water evaporation component, which includes a plurality of annular roll curtains 21 arranged at intervals. The upper end and the lower end of the annular roll curtain 21 are connected by a rotating shaft 22 respectively, and the rotating shaft 22 drives the endless roll by a driving device. The cloth curtain 21 rotates, and the lower part of the annular roll cloth curtain 21 is infiltrated in the water tank 12. The driving device is a motor (not shown in the figure). The rotating shaft 22 includes an upper rotating shaft 221 on the upper part and a lower rotating shaft 222 located in the water tank. The annular roller blind 21 is sleeved on the two rotating shafts, and one of the rotating shafts is driven by the driving device to rotate. Thus, the up-and-down movement of the ring-shaped roller blind 21 is realized, and the rotating shaft 22 here is arranged on the roller blind support.

As shown in Figure 1, the specific work is as follows.

The circulating water pump 11 sends the water in the water tank 12 into the water storage tank 13 through the water pipe 4, and the water in the water storage tank 13 is sprayed on the water evaporation carrier 14. The air driven by the fan assembly 3 is sucked in from the air inlet opening 71 of the casing 7 and passes through the water evaporation carrier 14 wetted with water. The water evaporates and absorbs the heat of vaporization to cool the water and air to form a primary cooling air 1B. The water flows back to the water tank 12 for recycling, and the cooled primary cooling air 1B is blown to the ventilation opening of the roller blind bracket 23 through the air duct of the fan assembly 3. At this time, the ring-shaped roller curtain 21 on the water evaporation component rotates, and the air passes through the wet curtain through the air outlet opening 72 of the casing 7 to form a secondary cooling air 2A. The water evaporates and absorbs the heat of vaporization to cool the air again. The non-evaporated water on the annular roller blind 21 on the roller blind support 23 flows into the water tank 12 for recycling.

Example 2

As shown in FIG. 4, this embodiment is different from the first embodiment in that the water tank 12 is separated into a first water tank 121 and a second water tank 122 by a partition plate 6 in the second embodiment, and the circulating water pump 11 is in communication with the first water tank 121. The lower part of each ring-shaped roller blind 21 is infiltrated in the second water tank 122.

When the water-cooled air conditioner is operating, the circulating water pump 11 sends the water in the first water tank 121 into the water storage tank 13 through the water pipe 4, and the water in the water storage tank 13 is sprayed on the water evaporation carrier 14. The air driven by the fan assembly is removed from the casing. The air inlet opening 71 of 7 is sucked in and passes through the water evaporation carrier 14 soaked with water. The water evaporates and absorbs the heat of vaporization to cool the water and air. The cooled water flows back to the first water tank 121 for recycling. The cooled air passes through the wind of the fan assembly. The road is blown toward the ventilation opening of the roller blind bracket 23. At this time, the cloth curtain on the water evaporation component rotates, and the air blows out through the moist ring-shaped cloth curtain 21 through the air outlet opening 72 of the casing 7, and the water evaporates and absorbs the heat of vaporization to cool the air again. The non-evaporated water on the ring-shaped roller blind 21 flows into the second water tank 122 for recycling and continuously provides evaporable cold water.

Example 3

Different from Embodiment 1, Embodiment 3 is provided with an ice cube box 5 above the water evaporation carrier 14. The bottom of the ice cube box 5 is formed with a drain hole 51 communicating with the water evaporation carrier 14, which is not shown in the figure. In this embodiment, an ice cube box is added above the water evaporation carrier 14, ice is added to the ice cube box, and the melted ice water is sprayed onto the water evaporation carrier to make the cooling effect of the water-cooled air conditioner better. The specific working process is here. No longer.

Example 4

The difference from Embodiment 1 is that the second water-cooling system 2 in Embodiment 4 is a water evaporation module, which includes a plurality of annular roll curtains 21 arranged at intervals, and an ice cube box is provided at the upper end of the annular roll curtain 21. 5. The lower end is disposed above the water tank 12, and the bottom of the ice cube box 5 is formed with drain holes 51 which are in one-to-one correspondence with each of the ring-shaped fabric curtains 21.

The ice cube box 5 can be added with ice in advance, and the melted ice water is sprayed on the ring-shaped roller curtain 21, and the non-evaporated water on the ring-shaped roller curtain is returned to the water tank for the first water cooling system. The curtain 21 is stationary, and the primary cooling air is cooled again under the action of ice water, so that the cooling effect of the water-cooled air conditioner is better. The specific working process will not be repeated here.

Example 5

The difference between this embodiment and Embodiment 4 is that each rotating shaft can be driven by a driving device, so that each of the ring-shaped roller blinds can move up and down. The present invention preferably soaks the lower part of the ring-shaped roller blinds in a water tank, and the air The wet cloth curtain is blown out through the air outlet opening 72 of the casing 7 to form a secondary cooling air 2A. The water evaporates and absorbs the heat of vaporization to cool the air again. As the ice water is sprayed on the upper part of the ring-shaped roller blind, its air cooling effect can achieve the best effect.

When the product is in operation, the circulating water pump 11 sends the water in the water tank 12 into the water storage tank 13 through the water supply pipe 4, and the water in the water storage tank 13 is sprayed on the water evaporation carrier. The air driven by the fan assembly is sucked in from the air inlet opening 71 of the casing 7 and passes through the water evaporation carrier 14 wetted with water. The water evaporates and absorbs the heat of vaporization to cool the water and air. The cooled water flows back to the water tank 12 for recycling. The cooled air is blown to the ventilation opening of the roller blind bracket 23 through the air duct of the fan assembly. At this time, the ring-shaped roller curtain 21 on the water evaporation component rotates, and at the same time, the ice water in the ice cube box 5 melts from the drain hole 51 at the bottom of the ice box 5 toward the ring-shaped roller curtain 21, which can make the ring-shaped roller cloth. The temperature of the curtain 21 is lower. The air is blown out through the moist ring-shaped curtain 21 through the air outlet opening 72 of the casing 7, and the water evaporates and absorbs the heat of vaporization to cool the air again. The non-evaporated water on the ring-shaped roller blind 21 flows into the water tank 12 for recycling and continuously provides evaporable cold water.

Example 6

The difference from Embodiment 5 is that in Embodiment 6, the water tank 12 is divided into a first water tank 121 and a second water tank 122 by a partition plate 6. The circulating water pump 11 is in communication with the first water tank 121. Infiltrated in the second water tank 122.

Specifically, as shown in FIG. 5, the first water tank 121 is placed at the lower end of the rear side of the housing 1, the circulating water pump 11 is placed in the first water tank 121, and the water storage tank 13 is placed above the water evaporation carrier 14 and fixed to the housing 7. On the inner wall, the upper water pipe 4 connects the circulating water pump 11 and the water storage tank 13.

The second water tank 122 is placed at the lower end of the front of the casing 7.

The water evaporation component is movably installed between the air outlet opening 72 of the casing 7 and the fan component 3, and the lower end portion is immersed in the water in the second water tank 122.

The ice cube box 5 is movably installed above the water evaporation component, and the lower water hole 51 at the bottom of the ice cube box 5 is aligned with the annular rolling curtain 21 on the water evaporation component.

When the product is in operation, the circulating water pump 11 sends the water in the first water tank 121 into the water storage tank 13 through the water supply pipe 4, and the water in the water storage tank 13 is sprayed on the water evaporation carrier 14. The air driven by the fan assembly is sucked in through the air inlet opening 71 of the casing 7 and passes through the water evaporation carrier 14 wetted with water. The water evaporates and absorbs the heat of vaporization to cool the water and air. The cooled water flows back to the first water tank 121 for circulation. During use, the cooled air is blown to the ventilation opening of the roller shutter bracket 23 through the air duct of the fan assembly. At this time, the ring-shaped roller shutter 21 on the water evaporation component rotates, and the air passes through the humid ring-shaped roller curtain 21 through the air from the casing 7. The opening 72 blows out, and the water evaporates and absorbs the heat of vaporization to cool the air again. At the same time, the ice water after the ice cubes in the ice cube box 5 melts from the drain hole 51 at the bottom of the ice cube box 5 toward the annular roller blind 21, which can lower the temperature of the annular roller blind 21 and enhance the cooling effect. The un-evaporated ice water on the ring-shaped roller blind 21 flows into the second water tank 122 for recycling, and continuously provides evaporable ice water.

The plurality of ring-shaped roller blinds 21 in the above embodiments are arranged in parallel, and a vent gap is formed between two adjacent ring-shaped roller blinds 21. A ventilation gap is also formed in the same ring-shaped roller blind. The direction of the air outlet of the tuyere remains the same. Of course, it can also be set to an inconsistent state, that is, the two form a certain angle, which can play a role of increasing the wind resistance to a certain extent and improving the cooling effect of the secondary cooling air. To repeat.

The rotating shaft 22 and the end face of the air outlet of the fan assembly 3 are preferably arranged vertically, and each of the annular rolling curtains 21 is arranged perpendicular to the horizontal plane, so that the rotating shaft can drive the annular rolling curtain 21 to move up and down.

Of course, the structure of the first water cooling system or the structure of the second water cooling system can be provided at the air inlet and the air outlet of the fan assembly; the first water cooling system and the second water cooling system can also be set after being adjusted. For the position of the air inlet and air outlet of the fan component, that is, the first water cooling system in FIG. 1 is set at the air outlet position of the fan component, and the second water cooling system is set at the air inlet position of the fan component, which can also achieve the effect of air cooling. I won't repeat them here.

Obviously, the foregoing embodiment is merely an example for clear description, and is not a limitation on the implementation. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. There is no need and cannot be exhaustive for all implementations. However, the obvious changes or variations introduced thereby are still within the protection scope of the present invention.
