[0044] A data center refers to a dedicated room used to house IT infrastructure such as computer servers, network equipment, and storage devices. Servers and other equipment in the data center will generate a large amount of heat when working, causing the air temperature in the data center to rise.

[0045] Data centers usually use refrigeration equipment such as air conditioners to cool down the equipment to prevent overheating.

[0046] However, because the air temperature in the data center is very high, the air conditioning equipment consumes a lot of energy for cooling.

[0047] In order to solve the technical problem of high refrigeration energy consumption of existing data center air-conditioning equipment, the present application proposes a data center cooling system, including a liquid storage tank, a heat exchanger and a driving member; the liquid storage tank is provided with a cooling medium inlet, a cooling medium outlet and a reflux port, the cooling medium inlet is used to be connected with a water supply pipeline so that the coolant in the water supply pipeline is input into the liquid storage tank, the heat exchanger is arranged in the data center, the cooling medium outlet is connected with the medium input port of the heat exchanger through the driving member, the driving member is used to transport the coolant in the liquid storage tank to the heat exchanger, the heat exchanger is used to heat exchange and cool the air in the data center, and the medium output port of the heat exchanger is connected with the reflux port so that the coolant in the heat exchanger is transported to the liquid storage tank.

[0048] The data center cooling system of the present application inputs the coolant from the water supply pipeline into the liquid storage tank, and then transports the coolant in the liquid storage tank to the heat exchanger through the driving member. Because the heat exchanger is located in the data center, the coolant in the heat exchanger exchanges heat with the air in the data center, thereby reducing the air temperature in the data center. Because the air temperature in the data center is reduced, the energy consumption of the air-conditioning equipment in the data center is reduced. Through the coordinated use of the data center cooling system of the present application and the data center air-conditioning equipment, the energy consumption of the data center air-conditioning equipment is reduced.

[0049] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0050] Reference Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the structure of a data center cooling system provided in an embodiment of the present application; Figure 2 A structural block diagram of a control system in a data center cooling system provided in an embodiment of the present application; Figure 3 A schematic diagram of the structure of the connection between the refrigeration system and the data center provided in the embodiment of the present application; Figure 4 for Figure 3 Schematic diagram of the local enlarged structure at point A in the middle.

[0051] In the embodiments of this application, refer to Figure 1 As shown, an embodiment of the present application provides a data center cooling system, including a liquid storage tank 100 , a heat exchanger 200 and a driving member 700 .

[0052] The liquid storage tank 100 is provided with a cooling medium inlet 111, a cooling medium outlet 112 and a reflux port 121. The cooling medium inlet 111 is used to communicate with the water supply pipeline 20 so that the cooling liquid in the water supply pipeline 20 can be input into the liquid storage tank 100. The heat exchanger 200 is arranged in the data center 10. The cooling medium outlet 112 is connected with the medium input port of the heat exchanger 200 through the driving member 700. The driving member 700 is used to transport the cooling liquid in the liquid storage tank 100 to the heat exchanger 200. The heat exchanger 200 is used to heat exchange and cool the air in the data center 10. The medium output port of the heat exchanger 200 is connected with the reflux port 121 so that the cooling liquid in the heat exchanger 200 can be transported to the liquid storage tank 100.

[0053] In the data center cooling system of the present application, the liquid storage tank 100 transports the cooling liquid to the liquid storage tank 100 through the water supply pipeline 20. The liquid storage tank 100 can be set below the ground to ensure that the temperature of the cooling liquid in the liquid storage tank 100 is relatively low.

[0054] It should be noted that the water supply pipeline 20 can be a municipal tap water pipeline, that is, the coolant is tap water, which not only reduces the cost but also facilitates the acquisition of the coolant.

[0055] The liquid storage tank 100 can be set inside or outside the data center 10. In the present embodiment, since the liquid storage tank 10 occupies a large area, the liquid storage tank 100 can be set outside the data center 10, so that more computer servers, network equipment, storage devices and other Internet technology infrastructure can be stored inside the data center 10.

[0056] The liquid storage tank 100 can also be set above the ground of the data center 10 or below the ground of the data center 10. When set above the ground of the data center 10, it is necessary to ensure that the liquid storage tank 100 has a heat insulation function to prevent the external temperature from being too high, which will cause the temperature of the coolant in the liquid storage tank 100 to rise.

[0057] The driving component 700 transports the water in the liquid storage tank 100 to the heat exchanger 200 located in the data center 10, so that the coolant in the heat exchanger 200 exchanges heat with the air in the data center 10, so that the air in the data center 10 is cooled. It should be noted that the driving component 700 can be a water pump.

[0058] It should be noted that the heat exchanger 200 is an existing water-cooled heat exchanger structure. The heat exchanger 200 includes a tube bundle, which is composed of multiple tubes. The tubes are usually made of metal, such as copper, stainless steel or titanium and other corrosion-resistant materials. The tubes can be in the form of straight tubes, U-shaped tubes or spiral tubes. In this embodiment, the diameter of the tube can be increased, thereby increasing the contact area between the tube and the air, and the length of the tube can be increased, so that the contact area between the tube and the air in the data center 10 is further increased. The coolant flows into the tube through the medium input port of the heat exchanger 200. The tube serves as a medium for heat transfer, so that the low-temperature coolant and the high-temperature air in the data center 10 are heat exchanged through the tube wall, thereby achieving the purpose of cooling the air in the data center 10. After the heat exchange, the air in the data center 10 is cooled, and the temperature of the coolant in the tube increases. Then, the heated coolant flows into the liquid storage tank 100 through the medium output port of the heat exchanger 200. In this process, the driving member 700 provides power for the coolant.

[0059] The data center cooling system of the present application inputs the coolant of the water supply pipeline 20 into the liquid storage tank 100, and then transports the coolant in the liquid storage tank 100 to the heat exchanger 200 through the driving member 700. Because the heat exchanger 200 is located in the data center 10, the coolant in the heat exchanger 200 exchanges heat with the air in the data center 10, thereby reducing the air temperature in the data center 10. Because the air temperature in the data center 10 is reduced, the energy consumption of the air-conditioning equipment in the data center 10 is reduced. Through the coordinated use of the data center cooling system of the present application and the data center air-conditioning equipment, the energy consumption of the data center air-conditioning equipment is reduced.

[0060] And because the data center cooling system of the present application cools the air in the data center 10, when the temperature in the data center 10 is appropriate, there is no need to turn on the data center air-conditioning equipment, thereby increasing the service life of the data center air-conditioning equipment and reducing the energy consumption of the data center air-conditioning equipment; of course, when the data center cooling system of the present application cools the air in the data center 10, if the temperature is not reduced to an appropriate temperature, the data center cooling system of the present application and the data center air-conditioning equipment can be used together to reduce the energy consumption of the data center air-conditioning equipment.

[0061] For example, the high-temperature hot air generated by the servers in a general large data center is generally around 30°C. After cooling by the data center cooling system of the present application, the temperature in the data center 10 can be reduced by 2°C, and the temperature can be reduced by about 5°C in winter. The overall temperature reduction from the original 30°C hot air to 20°C to the current 28°C or 25°C cooling to 20°C can greatly reduce the energy consumption of the data center air conditioning equipment.

[0062] In another embodiment, it also includes a first connecting line 300, a first switch valve 310 and a first temperature sensor 320. The driving member 700 is connected to the medium input port through the first connecting line 300. The first switch valve 310 and the first temperature sensor 320 are both arranged on the first connecting line 300. The first switch valve 310 is used to open or close the first connecting line 300. The first temperature sensor 320 is used to detect the temperature of the coolant in the first connecting line 300.

[0063] In this embodiment, the coolant in the liquid storage tank 100 is transported to the heat exchanger 200 through the first connecting pipe 300. The first connecting pipe 300 is provided with a first switch valve 310 and a first temperature sensor 320. When the temperature detected by the first temperature sensor 320 is higher than the temperature in the data center 10, the first switch valve 310 can be closed to prevent the heat exchanger 200 from heating the air in the data center 10. When the temperature detected by the first temperature sensor 320 is lower than the temperature in the data center 10, the first switch valve 310 can be opened, so that the heat exchanger 200 can cool the air in the data center 10.

[0064] In one embodiment, a controller 500 is further included, the first switch valve 310 is a first solenoid valve, and the first solenoid valve, the first temperature sensor 320 and the driving member 700 are all electrically connected to the controller 500 .

[0065] The controller 500 is used to control the opening and closing of the first switch valve 310 and the driving member 700 according to the temperature detected by the first temperature sensor 320 .

[0066] In this embodiment, refer to Figure 2 As shown, when the temperature detected by the first temperature sensor 320 is greater than or equal to the first preset temperature, the controller 500 controls the first switch valve 310 and the driving member 700 to close; when the temperature detected by the first temperature sensor 320 is less than the first preset temperature, the controller 500 controls the first switch valve 310 and the driving member 700 to open. By opening or closing the first switch valve 310 and the driving member 700 through the controller 500, the labor cost is reduced, and the temperature of the coolant in the heat exchanger 200 is ensured to be lower than the first preset temperature. The first preset temperature is usually the temperature of the data center 10 when the air conditioning equipment is not used. The preset temperature can usually be set to 30°C.

[0067] In one embodiment, the liquid storage tank 100 includes a first water tank 110, a second water tank 120, a third connecting pipe 130 and a third switch valve 140, the cooling medium inlet 111 and the cooling medium outlet 112 are both arranged on the first water tank 110, the reflux port 121 is arranged on the second water tank 120, the first water tank 110 is connected with the second water tank 120 through the third connecting pipe 130, the third switch valve 140 is arranged on the third connecting pipe 130, and the third switch valve 140 is used to open or close the third connecting pipe.

[0068] In this embodiment, in order to prevent the coolant refluxed from the medium outlet of the heat exchanger 200 from causing the temperature of the coolant in the liquid storage tank 100 to rise, this embodiment sets the liquid storage tank 100 as two independent first water tanks 110 and second water tanks 120. The first water tank 110 and the second water tank 120 are connected by a third connecting pipe 130. The third connecting pipe 130 is provided with a third switch valve 140. When the temperature in the second water tank 120 is lower than the preset temperature, the third switch valve 140 can be opened.

[0069] It should be noted that the coolant in the second water tank 120 is also connected to domestic water through a pipeline for people to use, for example, it is transported to the bathroom through a pipeline for flushing the toilet or for people to wash their hands.

[0070] In other possible embodiments, the first water pool 110 is disposed under the ground of the data center 10 , and the second water pool 120 is disposed on the ground of the data center 10 .

[0071] In this embodiment, the first water tank 110 is set under the ground of the data center 10, which can prevent the temperature of the coolant in the first water tank 110 from being affected by the external temperature, and ensure that the coolant in the first water tank 110 has a cooling effect, thereby improving the heat exchange efficiency of the heat exchanger 200.

[0072] At the same time, the second water pool 120 is arranged on the ground of the data center 10 for convenient use by people.

[0073] In other embodiments, the third switch valve 140 is a one-way valve, which is used to allow the coolant in the first water pool 110 to flow into the second water pool 120 in one direction.

[0074] In this embodiment, since the third switch valve 140 is a one-way valve, it can prevent the coolant in the first water pool 110 from flowing into the second water pool 120, thereby avoiding the use of excessive coolant and causing waste.

[0075] In some possible embodiments, a third temperature sensor 600 is further included. The third temperature sensor 600 is disposed in the second water pool 120 . The one-way valve is an electromagnetic one-way valve. Both the electromagnetic one-way valve and the third temperature sensor 600 are electrically connected to the controller 500 .

[0076] The controller 500 is used to control the opening and closing of the electromagnetic one-way valve according to the temperature detected by the third temperature sensor 600.

[0077] In this embodiment, refer to Figure 2 As shown, when the temperature detected by the third temperature sensor 600 is greater than or equal to the third preset temperature, the controller 500 controls the electromagnetic one-way valve to close; when the temperature detected by the third temperature sensor 600 is less than the third preset temperature, the controller 500 controls the electromagnetic one-way valve to open. By opening or closing the electromagnetic one-way valve through the controller 500, it is ensured that the cooling liquid entering the first water pool 110 is lower than the third preset temperature, and the third preset temperature is less than or equal to the temperature of the air in the data center 10.

[0078] In other possible embodiments, it also includes a second connecting line 400, a second switch valve 410 and a second temperature sensor 420. The medium output port is connected to the reflux port 121 through the second connecting line 400. The second switch valve 410 and the second temperature sensor 420 are both arranged on the second connecting line 400. The second switch valve 410 is used to open or close the second connecting line 400. The second temperature sensor 420 is used to detect the temperature of the coolant in the second connecting line 400.

[0079] In this embodiment, the heat exchanger 200 is connected to the reflux port 121 via a second connecting pipe 400, and a second switch valve 410 and a second temperature sensor 420 are provided on the second connecting pipe 400. By providing the second switch valve 410 and the second temperature sensor 420, it is convenient to inspect and repair the heat exchanger 200, and it can be determined whether the heat exchanger 200 has a fault.

[0080] In some possible embodiments, a first pressure sensor 330 and a second pressure sensor 430 are further included. The first pressure sensor 330 is arranged on the first connecting pipe 300, and the first pressure sensor 330 is used to detect the water pressure in the first connecting pipe 300. The second pressure sensor 430 is arranged on the second connecting pipe 400, and the second pressure sensor 430 is used to detect the water pressure in the second connecting pipe 400.

[0081] In this embodiment, by detecting the water pressure on the first connecting pipe 300 and the second connecting pipe 400, it is possible to determine whether the first connecting pipe 300 and the second connecting pipe 400 are damaged, thereby improving the maintenance efficiency of the first connecting pipe 300 and the second connecting pipe 400.

[0082] In another possible embodiment, referring to Figure 3 and Figure 4As shown, a refrigeration system 800 is also included. An air inlet 11 and an air outlet 12 are provided on the data center 10. The air outlet 810 of the refrigeration system 800 is connected to the air inlet 11, and the air inlet 820 of the refrigeration system 800 is connected to the air outlet 12. The heat exchanger 200 is a fin-type heat exchanger, which is arranged in the air outlet 12. The fin-type heat exchanger includes a base tube 210 and a plurality of fins 220 arranged on the base tube 210. A gap 900 is provided between each fin 220. The gap 900 is configured to connect the data center 10 with the air inlet 820 of the refrigeration system 800 so as to reduce the temperature of the air introduced into the air inlet 820 through each fin 220.

[0083] It should be noted that the refrigeration system 800 can be existing air-conditioning equipment, air-cooling equipment, water-cooling equipment, temperature-reducing equipment, etc.

[0084] In this embodiment, the refrigeration system 800 is the existing data center air-conditioning equipment. The refrigeration system 800 can be a precision air-conditioning. The working principle is that the air outlet 810 of the refrigeration system 800 blows air to cool the data center 10, and the air in the data center 10 is discharged to the air inlet 820 of the refrigeration system 800 through the exhaust port 12, thereby circulating.

[0085] Since the heat exchanger 200 is disposed in the air outlet 12 , the air entering the air inlet end 820 of the refrigeration system 800 is cooled, thereby reducing the energy consumption of the refrigeration system 800 .

[0086] In this embodiment, the heat exchanger 200 is specifically a finned heat exchanger, which is a device widely used in gas and liquid heat exchangers. The heat transfer effect is enhanced mainly by adding fins 220 to the base tube 210. A gap 900 is provided between each fin 220. The air in the data center 10 enters the air inlet end 820 of the refrigeration system 800 through the gap 900, so that the temperature of the air entering the air inlet end 820 can be reduced through each fin 220, thereby improving the performance of the entire heat exchanger 200.

[0087] In this embodiment, the heat exchanger 200 lowers the temperature of the air in the data center 10 and lowers the temperature of the air entering the air inlet 820 of the refrigeration system 800, thereby further reducing the energy consumption of the refrigeration system 800. Moreover, because the heat exchanger 200 is disposed in the exhaust port 12, there is continuous wind passing through the exhaust port 12, thereby improving the heat exchange efficiency of the heat exchanger 200.

[0088] In summary, the data center cooling system of the present application inputs the coolant from the water supply pipeline 20 into the liquid storage tank 100, and then transports the coolant in the liquid storage tank 100 to the heat exchanger 200 through the driving member 700. Because the heat exchanger 200 is located in the data center 10, the coolant in the heat exchanger 200 exchanges heat with the air in the data center 10, thereby reducing the air temperature in the data center 10. Because the air temperature in the data center 10 is reduced, the energy consumption of the air-conditioning equipment in the data center 10 is reduced. Through the coordinated use of the data center cooling system and the data center air-conditioning equipment of the present application, the energy consumption of the data center air-conditioning equipment is reduced.
