[0032] The utility model provides a cooling device.

[0033] See also Figure 1 In one embodiment of the utility model, the cooling device is applied to an air cooler, and the cooling device includes a shell 1, a compressor 2, a mounting seat 3, a water curtain 4 and a condenser 5; the compressor 2 is arranged in the shell 1; the mounting seat 3 is arranged in the shell 1, and the mounting seat 3 has a mounting groove 31 with an opening facing upward; the water curtain 4 is arranged in the shell 1, and the mounting groove 31 is located below the water curtain 4; the condenser 5 is connected to the compressor 2 through a first delivery pipe 51, and the condenser 5 is arranged in the mounting groove 31, and the top of the condenser 5 is located below the opening of the mounting groove 31, and a liquid gap for water flow is formed between the bottom end of the condenser 5 and the bottom wall of the mounting groove 31.

[0034] The technical solution of the present invention is to position the top end of the condenser tube 5 below the opening of the mounting groove 31, thereby increasing the space between the top end of the condenser tube 5 and the opening for the flow of cooling water. By providing a liquid gap for the flow of water between the bottom end of the condenser tube 5 and the bottom wall of the mounting groove 31, the heat exchange area between the cooling water and the condenser tube 5 is increased, thereby improving the cooling effect of the cooling water on the condenser tube 5.

[0035] In this embodiment, the cooling device further includes a water curtain 4 assembly and a water supply assembly. The water curtain 4 assembly comprises an interconnected water curtain 4 and a water curtain 4 frame. The water supply assembly comprises a water pump and a water tank. The water pump is used to transport water from the water tank to the water curtain 4 frame via a pipe. The water flows through the water curtain 4 frame onto the water curtain 4, allowing the water on the water curtain 4 to remove heat from the outside air through evaporation. After evaporation, the water on the water curtain 4 flows into the mounting groove 31 of the mounting base 3, thereby cooling the condenser 5 in the mounting groove 31. The cooling water eventually flows from the mounting groove 31 into the water tank, where the water in the water tank is circulated again by the water pump. The condenser 5 may include a pipe body and first delivery pipes 51 disposed at both ends of the pipe body. The first delivery pipe 51 at the end near the compressor 2 is connected to the compressor 2 to deliver refrigerant to the condenser 5, and the first delivery pipe 51 at the end near the evaporator is connected to the evaporator to deliver liquid refrigerant to the evaporator. In the longitudinal direction of the mounting base 3, the length of the mounting groove 31 can be greater than the length of the tube body, so that a cavity for cooling water to flow is formed between the condenser tube 5 and the side walls of the mounting groove 31 at both ends along the longitudinal direction, thereby increasing the heat exchange area between the cooling water and the condenser tube 5. By providing a liquid flow gap for water flow between the bottom end of the condenser tube 5 and the bottom wall of the mounting groove 31, and by arranging the top end of the condenser tube 5 below the opening of the mounting groove 31, there is a liquid flow space between the condenser tube 5 and the plane where the opening of the mounting groove 31 is located and the bottom wall 322 of the mounting groove 31, thereby allowing the tube body to be completely immersed in the cooling water. In addition, the tube body can be arranged in a spiral shape, thereby increasing the heat exchange area between the tube body and the cooling water, thereby improving the heat exchange effect between the cooling water and the condenser tube 5.

[0036] like Figure 2 and Figure 4 As shown, the length direction of the mounting groove 31 extends along the first direction, the length direction of the condenser 5 extends along the first direction, the condenser 5 is spiral-shaped, the water curtain 4 is provided on the mounting seat 3 and is located on one side of the mounting groove 31, and the compressor 2 is located on the other side of the mounting groove 31 away from the water curtain 4.

[0037] In this embodiment, the mounting groove 31 is formed as a groove extending in a straight line, thereby facilitating the processing of the mounting groove 31. The condenser tube 5 is formed as a spiral extending in a straight line, replacing the existing ring-shaped or arc-shaped condenser tube 5. This simplifies the processing of the condenser tube 5, avoids the problem of a large pitch at the bend of the condenser tube 5, and makes it easier to expand the outer diameter of the condenser tube 5, thereby improving the efficiency of the condenser tube 5 in transporting the refrigerant.

[0038] like Figure 2 and Figure 4As shown, the mounting seat 3 has a water collecting groove 32 located above the mounting groove 31, the water curtain 4 is arranged on the water collecting groove 32, and the water collecting groove 32 is provided with a slope portion 321 near one side of the mounting groove 31. The slope portion 321 is arranged obliquely from the water collecting groove 32 to the mounting groove 31, so that the cooling water in the water collecting groove 32 is guided to the mounting groove 31 through the slope portion 321.

[0039] In this embodiment, the water curtain 4 can be provided in multiple numbers, and the water collecting groove 32 can be provided in multiple numbers according to the number of the water curtain 4. Each water curtain 4 is arranged in one-to-one correspondence with each water collecting groove 32, so that the cooling water on the water curtain 4 can be better collected into the water collecting groove 32. The water collecting groove 32 is used to store the cooling water dripping on the water curtain 4. By arranging the water collecting groove 32 above the mounting groove 31, a height difference is formed between the water collecting groove 32 and the mounting groove 31, so that the cooling water can flow into the mounting groove 31 more conveniently under the action of gravity. In order to make the cooling water flow from the water collecting groove 32 into the mounting groove 31 more conveniently, the slope portion 321 is arranged to connect the groove bottom wall 322 of the water collecting groove 32 and the side wall of the mounting groove 31. The slope portion 321 forms a water conveying channel connecting the water collecting groove 32 and the mounting groove 31. By arranging the slope portion 321 to be inclined from the water collecting groove 32 to the mounting groove 31, the cooling water in the water collecting groove 32 can flow into the mounting groove 31 under the action of gravity, and the cooling water in the water collecting groove 32 can be prevented from overflowing out of the water collecting groove 32 due to excessive amount.

[0040] As shown in the drawings, Figure 3 The water collecting groove 32 has a groove bottom wall 322 and a plurality of flow guide side walls 323. The groove bottom wall 322 is connected to the slope portion 321, and the plurality of flow guide side walls 323 are arranged around the groove bottom wall 322 and are inclined from the groove opening of the water collecting groove 32 to the groove bottom wall 322.

[0041] In this embodiment, the water collecting groove 32 has a water conveying channel located above the slope portion 321, and the water conveying channel connects the water collecting groove 32 and the mounting groove 31. By arranging the groove bottom wall 322 to connect the slope portion 321 and arranging the plurality of flow guide side walls 323 around the groove bottom wall 322, the cooling water on the water curtain 4 drips onto the flow guide side walls 323 and gradually converges to the groove bottom wall 322. The cooling water flows into the mounting groove 31 through the groove bottom wall 322 and the water conveying channel, thereby reducing the resistance of the cooling water flowing in the water collecting groove 32 and improving the conveying efficiency of the cooling water in the water collecting groove 32 to the mounting groove 31.

[0042] As shown in the drawings, Figure 5As shown, the bottom wall of the mounting groove 31 is in an arc shape that bulges toward the side away from the opening. The bottom wall of the mounting groove 31 has a drainage hole 311 connected to the mounting groove 31. The drainage hole 311 is located at one end of the mounting groove 31 away from the water curtain 4.

[0043] In this embodiment, the shape of the bottom wall of the arc-shaped mounting groove 31 is more compatible with the spiral shape of the condenser tube 5, so that the distance between the bottom end of the condenser tube 5 and the bottom wall of the mounting groove 31 is a liquid gap, which makes it easier to adjust the size of the liquid gap, so that the cooling water has a better cooling effect on the bottom end of the condenser tube 5. The provision of the drainage hole 311 allows the cooling water to be transported into the water tank through the drainage hole 311 under the action of gravity, thereby more conveniently transporting the cooling water from the mounting groove 31 to the water tank, so that the higher temperature cooling water in the mounting groove 31 can flow into the water tank in a timely manner, thereby improving the replacement efficiency of the cooling water in the mounting groove 31 and ensuring the cooling efficiency of the cooling water in the mounting groove 31.

[0044] like Figure 2 and Figure 4 As shown, the end of the mounting groove 31 away from the drainage hole 311 has a water inlet for transporting cooling water in the water receiving groove 32, and the mounting seat 3 has a drainage groove 312, and the drainage groove 312 is located on the side of the mounting groove 31 close to the drainage hole 311, and the top of the mounting groove 31 close to the end of the drainage hole 311 has a notch 313, and the notch of the drainage groove 312 is connected to the notch 313.

[0045] In this embodiment, cooling water from the water curtain 4 flows into the water receiving trough 32, then flows into the mounting trough 31 through the water inlet, gradually filling the mounting trough 31 with cooling water. The cooling water then flows into the water tank through the drain hole 311. When the cooling water fills the mounting trough 31 at a rate much faster than the cooling water flows out of the drain hole 311, the water level in the mounting trough 31 gradually rises and submerges the notch 313. The cooling water then flows through the notch 313 into the drain trough 312, which then connects to the water tank, allowing the cooling water to flow back into the water tank. This prevents the cooling water in the mounting trough 31 from overfilling and overflowing.

[0046] like Figure 2 、 Figure 4 and Figure 5 As shown, the cooling device also includes a partition 6, the mounting groove 31 includes a first mounting groove 314 and a second mounting groove 315, and the partition 6 is arranged in the mounting groove 31. The partition 6 is used to separate the mounting groove 31 into the first mounting groove 314 and the second mounting groove 315, and the first mounting groove 314 and the second mounting groove 315 are both provided with the condensing pipe 5.

[0047] In this embodiment, the mounting groove 31 is divided into a first mounting groove 314 and a second mounting groove 315 by providing a partition 6. The first mounting groove 314 and the second mounting groove 315 are both provided with a condensing tube 5, thereby making it easier to install the two condensing tubes 5 in the mounting base 3. The mounting base 3 can be increased in width according to the cooling requirements of the air cooler, and multiple partitions 6 are provided at intervals according to the width of the mounting groove 31, so that the mounting groove 31 can be divided into more mounting grooves 31 for the assembly of the condensing tube 5, thereby enabling multiple condensing tubes 5 to adapt to multiple evaporators and multiple compressors 2, thereby improving the cooling efficiency of the air cooler.

[0048] like Figure 1 As shown, the cooling device also includes a second delivery pipe 7 and a seal, one end of the second delivery pipe 7 is connected to the compressor 2, and the other end of the second delivery pipe 7 has a first port 71 and a second port 72, and the two condensing pipes 5 are connected to the first port 71 and the second port 72 one-to-one, so that the condensing pipes 5 are suspended in the mounting groove 31, and the first port 71 and the second port 72 are both provided with the seal.

[0049] In this embodiment, in order to improve the airtightness of the connection between the two condensers 5 and the compressor 2, one end of a second delivery pipe 7 is connected to the compressor 2, and the other end of the second delivery pipe 7 has a first port 71 and a second port 72. The two condensers 5 are connected to the first port 71 and the second port 72 one-to-one through the first delivery pipe 51, and the connection between the first delivery pipe 51 and the first port 71 or the second port 72 is sealed by a seal (not marked). The seal can be a rubber plug and a coating sealant, etc.

[0050] like Figure 3 As shown, the cooling device further includes a cover plate 8 , which covers the opening. The cover plate 8 has a through hole 81 communicating with the mounting groove 31 , and the through hole 81 is used for allowing the first delivery pipe 51 to extend out of the mounting groove 31 .

[0051] In this embodiment, to further prevent cooling water from overflowing from the mounting groove 31, a cover plate 8 is provided to detachably cover the opening, so that the cover plate 8 seals the opening of the mounting groove 31. To facilitate hanging the condenser 5 in the mounting groove 31, the cover plate 8 is provided with a through hole 81 communicating with the mounting groove 31, so that the first delivery pipes 51 at the liquid inlet and liquid outlet ends of the condenser 5 can extend from the mounting groove 31 through the through hole 81 to the outside of the mounting groove 31, thereby making it easier for the first delivery pipe 51 at the liquid inlet end to connect to the compressor 2, and for the first delivery pipe 51 at the liquid outlet end to connect to the evaporator.
