[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example: Figure 1-7 As shown, a cooling device comprises a shell 1, a heat exchange device 2 is arranged inside the shell 1, a longitudinally transparent first channel 3 and a transversely transparent second channel 4 are arranged inside the heat exchange device 2, a moisture-permeable barrier 5 is arranged between the first channel 3 and the second channel 4, a spray pipe 6 is arranged at the upper end of the first channel 3, a spray water tank 8 is arranged at the lower end, an air inlet is arranged at one end of the second channel 4, and a fan 7 is arranged at the other end. The first channel 3 is arranged in multiple groups side by side, and each group of the first channels 3 is arranged in multiple groups side by side, and the second channel 4 is also arranged in multiple groups side by side, and each group of the second channels 4 is also arranged in multiple groups side by side.

[0026] The spray water tank 8 is disposed at the lower end opening of the first channel 3 and is opened toward the heat exchange device 2 , and is used to receive the circulating water flowing out of the first channel 3 .

[0027] like Figure 2-3 As shown, a fin tube 9 is further provided between the air inlet and the heat exchange device 2 , and both ends of the fin tube 9 are provided with openings, wherein the opening at one end is a high-temperature medium inlet 10 , and the opening at the other end is a medium-temperature medium outlet 11 .

[0028] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a heat exchange shell 12 is provided at the lower part of the outer shell 1. The upper end of the heat exchange shell 12 is connected to the spray water tank 8, and the lower end is connected to the spray pipe 6 through the upper water pipe 13. A spray water pump 14 is provided on the upper water pipe 13, and a spray head 19 facing the first channel 3 is provided on the spray pipe 6.

[0029] like Figure 6-7 As shown, a tube pass 15 is provided in the heat exchange tube shell 12 , one end of the tube pass 15 is a medium temperature medium inlet 16 , and the other end is a low temperature medium outlet 17 . The medium temperature medium inlet 16 is connected to the medium temperature medium outlet 11 through a connecting pipe 18 .

[0030] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in this embodiment, water is sprayed onto the heat exchange device 2 through the spray head 19, and then flows downward along the first channel 3 and flows into the spray water box 8. At the same time, the fan 7 drives the air to flow from the air inlet through the fin tube 9 and then through the second channel 4 and then flows out. In this way, water flows from the first channel 3 and air flows from the second channel 4. The wind and water do not interfere with each other, and the floating water phenomenon does not occur. The wind and water movement in the entire heat exchange device 2 are very stable. At the same time, in this embodiment, the heat exchange device 2 is made of wet curtain paper, which can make water flow in the first channel 3 and wet the entire heat exchange device 2 but will not flow into the second channel 4. Both sides of the moisture permeable barrier 5 are plane settings. The moisture permeable barrier 5 is located between the adjacent first channel 3 and the second channel 4, separating the first channel 3 and the second channel 4. The material of the moisture permeable barrier 5 is also the wet curtain paper. When working, the water in the first channel 3 will soak the moisture permeable barrier 5 and make it in a wet state, but the moisture permeable barrier 5 can ensure that the water will not flow into the second channel 4. In this way, when the fan 7 is working, the air flows from the air inlet through the fin tube 9 and then into the second channel 4, in which the entire heat exchange device 2 is cooled, and then flows out driven by the fan 7. The moisture-permeable barrier 5 on the side of the second channel 4 is in a moist state, which can increase the evaporation of water under the action of the flowing air, thereby improving the cooling effect.

[0031] The fin tube 9, the heat exchange device 2 and the fan 7 are installed at the same horizontal position. The medium to be cooled first enters the fin tube 9 from the high-temperature medium inlet 10, and then flows out from the medium-temperature medium outlet 11 after circulating through the fin tube 9. One side of the fin tube 9 is the air inlet, and the other side is the second channel 4. In this way, the air used for cooling the circulating water is first heated by the fin tube 9 and then used for cooling the circulating water. At the same time, it can also take away part of the heat of the medium in the fin tube 9, reduce the original moisture content of the air, and allow the air passing through the second channel 4 to take away more moisture, thereby increasing the evaporation of the second channel 4 and improving the cooling effect of the circulating water. For example, in the summer in the southern region, the air temperature is A1, the moisture content is B1, and the relative humidity is C1. The air needs to absorb 100% - C1 of water to continue to absorb water to the saturation state. That is, when the air temperature is A1, it can take away 100% - C1 of water at most. When the air is heated to the temperature A2 by the fin tube 9, the moisture content is B2 and the relative humidity is C2. The air needs to absorb 100% - C2 of water to continue to absorb water to the saturation state. That is, when the air temperature is A2, it can take away 100% - C2 of water at most. A2>A1, the moisture content B1 remains unchanged, and correspondingly, the relative humidity C2<C1. Therefore, after the temperature rises, the air's water absorption capacity is greatly improved, so that it can take away more water when passing through the second channel 4, thereby increasing the evaporation of the second channel 4 and improving the cooling effect of the circulating water. Figure 7 As shown, the air in the air inlet is the air in the environment, which is heated by the fin tube 9 to become high-temperature and low-humidity air, and then cooled by the second channel 4 to become high-humidity air. At the same time, the air passing through the fin tube 9 first exchanges heat with the medium in the fin tube 9 to initially cool the medium. In this way, the high-temperature medium inlet 10 enters the high-temperature medium, and the medium-temperature medium flows out from the medium-temperature medium outlet 11 after passing through the fin tube 9. The heat in the medium is used to improve the cooling effect of the circulating water and the medium is initially cooled.

[0032] In this embodiment, Figure 2 As shown, the heat exchange tube shell 12 is arranged at the lower part of the spray water tank 8, and multiple groups of heat exchange tube shells 12 are arranged side by side. In this embodiment, the uppermost heat exchange tube shell 12 is connected to the spray water tank 8, and adjacent heat exchange tube shells 12 are connected in sequence. The lowermost heat exchange tube shell 12 is connected to the water outlet header, and the water outlet header is connected to the upper water pipe 13.

[0033] like Figure 5-7As shown, in this embodiment, the tube pass 15 is a coil, and can also be other forms, such as an S-shaped tube, etc. At least one group of tube passes 15 is arranged in each heat exchange tube shell 12, and the tube passes 15 in all the heat exchange tube shells 12 are connected in series in sequence. The medium-temperature medium flows out from the medium-temperature medium outlet 11, and then flows into the tube pass 15 from the medium-temperature medium inlet 16 through the connecting pipe 18. The medium in the tube pass 15 is cooled again by the circulating water in the heat exchange tube shell 12, and the low-temperature medium flows out from the low-temperature medium outlet 17. At the same time, the temperature of the circulating water in the heat exchange tube shell 12 increases, and flows into the spray pipe 6 through the upper water pipe 13 and sprays on the heat exchange device 2 to complete the cooling of the circulating water.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
