[0002] A data center is a facility used to centrally store, manage, and process large amounts of data. It typically includes network equipment, servers, storage systems, power equipment, cooling equipment, and physical security measures. Data centers consume a large amount of electricity, so effective energy management and cooling systems are required to ensure the normal operation and stability of the equipment. The cooling system includes air cooling systems and water cooling systems.

[0003] However, in the operation process of the data center water cooling system in the prior art, the heat generated by the equipment is extracted through cooling water, and then the cooling water is dissipated through the heat exchange equipment to circulate and cool the equipment. However, certain agents are often added to the cooling water, and the extracted hot cooling water cannot be used directly, which easily causes a certain waste of thermal energy resources. For this reason, we provide a heat exchange device for cooling water in a data center to solve the above problems. Utility Model Content

[0031] An adjusting assembly is provided at the bottom of the collecting shell 6, and the angle of the spraying pipe 9 is adjusted by the adjusting assembly.

[0032] Specifically, the compression refrigerator 2 is used to generate low-temperature refrigerant in the refrigeration system, and the plate heat exchanger 3 is used to transfer the coldness of the refrigerant to the medium that needs to be cooled. The plate heat exchanger 3 can transfer the low-temperature and low-pressure steam of the refrigerant (such as Freon, ammonia, etc.) through the plates of the plate heat exchanger 3 to exchange heat with the high-temperature coolant entering through the delivery pipe 4. The heat of the refrigerant is transferred to the coolant, which reduces the temperature of the coolant, thereby achieving a cooling effect, and can effectively exchange heat and cool the cooling water. Specific embodiment 2

[0034] See also Figure 1-5 On the basis of the specific embodiment 1, a water pump 12 is connected to one side of the booster pump 11, and the other end of the water pump 12 is connected to the collecting shell 6. The top of the water storage box 10 is fixedly connected to the collecting shell 6, and the surface of the spraying pipe 9 is movably connected to the inner wall of the collecting shell 6 through a bearing. The adjustment component includes a driving motor 13, which is fixed to the bottom of the collecting shell 6, and the top output end of the driving motor 13 is fixedly connected to the spraying pipe 9.

The drain pipe 5 is connected to the plate heat exchanger 3, and the low-temperature coolant can be discharged into the machine room again to achieve the effect of circulating cooling. The temperature conduction pipe 8 is spiral-shaped and made of copper tube material, which can effectively transfer heat. A nozzle is connected to one side of the spray pipe 9. There are five nozzles, which are evenly arranged up and down, and water can be evenly sprayed on the surface of the heat exchange tube 7. A gap is set between the collecting shell 6 and the heat exchange tube 7 to ensure the normal circulation of air. Specific embodiment three

[0037] See also Figure 1-5 On the basis of the specific embodiment 1 and the specific embodiment 2, columns 15 are fixedly connected on both sides of the collecting shell 6, the bottom of the column 15 is fixedly connected to the base 1, the top of the column 15 is fixedly connected to the heat exchange tube 7, one end of the delivery pipe 4 is connected to the temperature conducting pipe 8, the bottom end of the temperature conducting pipe 8 is connected to the plate heat exchanger 3, one end of the drainage pipe 5 is connected to the plate heat exchanger 3, the compression refrigerator 2 is connected to the plate heat exchanger 3 through a pipeline, one side of the collecting shell 6 is connected to a water injection pipe 16, and the other end of the water injection pipe 16 is connected to a water storage tank 17.

[0038] Specifically, the water pumping pipe 12 is connected between the booster pump 11 and the collecting shell 6, and the water in the collecting shell 6 can be pumped out again to achieve the circulation effect. The driving motor 13 can drive the spraying pipe 9 to rotate, adjust the spraying angle of the spraying pipe 9, and increase the range of water spraying.

[0039] The working principle of the utility model is as follows: the high-temperature cooling water generated by the equipment in the data center is discharged through the delivery pipe 4, and the discharged high-temperature cooling water enters the heat exchange tube 7 for circulation, and then the booster pump 11 is started by the external controller, and the booster pump 11 draws the water in the collection shell 6 into the water storage box 10, and delivers it to the spray pipe 9 through the water inlet 14, and the water is sprayed onto the surface of the heat exchange tube 7 through the spray pipe 9, and the water sprayed onto the surface of the heat exchange tube 7 conducts the temperature of the coolant, which plays a role in recovering heat energy. At the same time, the water sprayed on the surface of the heat exchange tube 7 will also evaporate and absorb heat under the influence of high temperature, so as to achieve the effect of cooling the coolant, and can also cool the coolant while recovering the waste heat;

[0040] Then, the drive motor 13 is started, and the drive motor 13 drives the spray pipe 9 to rotate, thereby increasing the spraying range of the water flow and improving the heat exchange effect on the coolant. The water after heat exchange falls into the collecting shell 6 again for collection. After the water temperature in the collecting shell 6 reaches the set value, it is discharged into the water storage tank 17, which is convenient for the staff to take hot water and plays a role in recovering heat energy. After that, the circulating cooling water is discharged into the plate heat exchanger 3 for heat exchange cooling. The cooled water enters the machine room again through the drain pipe 5 to achieve the effect of circulating cooling.
