[0003] Therefore, it is necessary to design a heat exchange device for a cooling tower to solve the problems in the above-mentioned background technology. Utility Model Content

The heat pipe 202 has a second drain port 204 and a liquid inlet 205 at both ends; the cooling assembly 6 is composed of a water pump 601, a first water inlet 602, a limit sleeve 603, a return pipe 604, a control valve 605, a water inlet pipe 606, a second water inlet 607, a second limit frame 608, a spray pipe 609 and a nozzle 610, and the lower end of the water pump 601 is connected to the return pipe 604, and the return pipe 604 is provided with a control valve 60 5. A first water inlet 602 is provided at the lower front portion of the water pump 601, a water inlet pipe 606 is connected to the upper end of the water pump 601, a plurality of limit sleeves 603 are connected to the outside of the water pump 601, a second water inlet 607 is connected to the upper end of the water inlet pipe 606, a spray pipe 609 is connected to one end of the second water inlet 607, a plurality of nozzles 610 are provided at the lower end of the spray pipe 609, and a plurality of second limit frames 608 are connected to the outside of the spray pipe 609.

[0026] Reference Figure 1 , Figure 5 and Figure 6 When the cooling tower is exchanging heat, the water vapor generated by the heat exchange will be directly discharged, which will carry a large amount of water vapor and cause a waste of water resources. However, if the spray water is used in a single cycle, it is necessary to wait for the spray water to cool down, which increases the time required for heat exchange and affects the heat exchange effect after spraying. The first limit frame 201 and the cooling tower 1 are connected by bolts, and the limit clamp 203 and the heat exchange tube 202 are connected by a snap connection. During heat exchange, hot water enters the heat exchange tube 202 through the liquid inlet 205, and heat is exchanged through the heat exchange tube 202.

Part of the sprayed water moves upward through the water vapor, and part of it is directly gathered at the bottom of the cooling tower 1. After being cooled to the required temperature, it can be used for subsequent spraying, forming a recycling of water resources, which is more environmentally friendly. The water supply of the water pump 601 can be supplied by circulating water and an external water source, thereby ensuring the sustainability of spraying, improving the heat exchange efficiency, and accelerating the heat exchange time.

The second limiting frame 608 and the cooling tower 1 are connected by bolts. When the heat source that needs to be exchanged enters the heat exchange tube 202, the spray pipe 609 sprays after being supplied with water by the water pump 601, so that the spray Water contacts the heat exchange tube 202, thereby forming heat transfer. Part of the sprayed water moves upward through the water vapor, and part of it directly gathers at the bottom of the cooling tower 1. After being cooled to the required temperature, it can supply water for subsequent spraying, forming a recycling of water resources, which is more environmentally friendly. The water pump 601 can supply water through circulating water and an external water source, thereby ensuring the sustainability of spraying, improving the heat exchange efficiency, and accelerating the heat exchange time.
