[0052] Data centers generate a lot of heat during operation. To ensure the normal operation of the data center, a cooling system is usually used to cool the data center.

[0053] In the related art, a data center usually includes a cooling tower and a hydraulic module. The hydraulic module is used to realize the circulation of cooling water in the cooling tower and the data center, and the cooling tower is used to cool the cooling water after passing through the data center. The cooling tower includes a fan, a dry coil, a spray assembly and a wet coil. The water outlet of the data center, the dry coil, the wet coil, the hydraulic module and the water inlet of the data center are connected in sequence. When the ambient temperature is high, the spray assembly works to cool the cooling water in the wet coil. When the ambient temperature is low, the fan works to cool the cooling water in the dry coil.

[0054] However, in the related art, regardless of whether the ambient temperature is low or high, the cooling water will flow through the dry coil and the wet coil, so that the cooling water encounters greater resistance, resulting in higher energy consumption of the hydraulic module.

[0055] The embodiment of the present disclosure provides a cooling system, which is used to cool a data center. The cooling system includes a cooling tower 1 and a hydraulic module 2. Figure 1As shown, the cooling tower 1 includes a dry coil 11, a wet coil 12, a first bypass pipeline 13, a second bypass pipeline 14, a fan 15 and a spray assembly 16. The first water outlet 101 of the data center, the dry coil 11, the wet coil 12, the hydraulic module 2 and the first water inlet 102 of the data center are connected in sequence, the two ends of the first bypass pipeline 13 are respectively connected to the two ends of the dry coil 11, the two ends of the second bypass pipeline 14 are respectively connected to the two ends of the wet coil 12, the first bypass pipeline 13 has a first bypass valve 131, and the second bypass pipeline 14 has a second bypass valve 141. The fan 15 is located above the dry coil 11, and the spray assembly 16 is located above the wet coil 12. The cooling system has a first cooling mode and a second cooling mode, as shown in FIG. Figure 2 As shown, in the first cooling mode, the first bypass valve 131 is closed and the second bypass valve 141 is opened, and the fan 15 is turned on. Figure 3 As shown, in the second cooling mode, the first bypass valve 131 is opened and the second bypass valve 141 is closed, and the fan 15 and the spray assembly 16 are turned on.

[0056] The ambient temperature in the first cooling mode is lower than the ambient temperature in the second cooling mode. When the ambient temperature is low, the fan 15 works so that air flows through the dry coil 11, thereby cooling the cooling water in the dry coil 11. When the ambient temperature is high, the temperature of the air is also high, and the operation of the fan 15 alone is not enough to cool the temperature in the wet coil 12. Therefore, the spray assembly 16 needs to be turned on at the same time, so that the spray assembly 16 sprays water toward the wet coil 12, so that the wet coil 12 is cooled by the joint action of the fan 15 and the spray assembly 16. The fan 15 can be a suction fan.

[0057] The technical solution provided by the embodiment of the present disclosure is that the cooling system has a first cooling mode and a second cooling mode. In the first cooling mode, the first bypass valve 131 is closed and the second bypass valve 141 is opened, so that the cooling water flowing out of the first water outlet 101 of the data center flows through the dry coil 11, the second bypass pipeline 14 and the hydraulic module 2 in sequence, and does not flow through the wet coil 12. In the second cooling mode, the first bypass valve 131 is opened and the second bypass valve 141 is closed, so that the cooling water flowing out of the first water outlet 101 of the data center flows through the first bypass pipeline 13, the wet coil 12 and the hydraulic module 2 in sequence, and does not flow through the dry coil 11. In this way, the flow path of the cooling water can be shortened, thereby reducing the flow resistance of the cooling water in the cooling tower 1, and further reducing the energy consumption of the hydraulic module 2.

[0058] In some examples, such as Figure 1As shown, the spray assembly 16 includes a spray pump 161, a nozzle 162 and a water collecting pan 163. The nozzle 162 is located above the wet coil 12, and the nozzle 162 and the spray pump 161 are connected through a water pipe. In the second cooling mode, the spray pump 161 can draw water from the water collecting pan 163, so that the nozzle 162 sprays water toward the wet coil 12. The water collecting pan 163 is located below the wet coil 12 and is used to collect water sprayed by the nozzle 162 to prevent the water from flowing to other devices and causing damage to other devices.

[0059] In some examples, the number of fans 15 may be one or more, which is not specifically limited in the embodiments of the present disclosure.

[0060] The implementation of the hydraulic module 2 is described below by way of example.

[0061] When the cooling water in the water supply pipeline 21 changes in volume due to temperature changes or other factors, the pressure of the water supply pipeline 21 may become unstable. In order to maintain the pressure of the water supply pipeline 21 to be stable, in some examples, such as Figure 4 As shown, the hydraulic module 2 includes a water supply pipeline 21, a circulating water pump 22 and an expansion tank 23. The wet coil 12, the water supply pipeline 21 and the first water inlet 102 of the data center are connected in sequence, and the circulating water pump 22 and the expansion tank 23 are located in the water supply pipeline 21. When the pressure of the water supply pipeline 21 is greater than the pressure in the expansion tank 23, the cooling water in the water supply pipeline 21 enters the expansion tank 23, so that the pressure in the water supply pipeline 21 is reduced. When the pressure of the water supply pipeline 21 is less than the pressure in the expansion tank 23, the cooling water in the expansion tank 23 enters the water supply pipeline 21, so that the pressure in the water supply pipeline 21 is increased. In this way, the pressure in the water supply pipeline 21 can be made relatively stable. When the pressure of the water pipeline 21 is equal to the pressure in the expansion tank 23, the cooling water in the water supply pipeline 21 no longer enters the expansion tank 23. Among them, the expansion tank 23 can be connected to the water supply pipeline 21 through a hose.

[0062] When the pressure of the water supply pipeline 21 is too low and the expansion tank 23 alone cannot bring the water supply pipeline 21 to a normal pressure, other components are required to supply water to the water supply pipeline 21 so that the water supply pipeline 21 can reach a normal pressure. Figure 4 As shown, the hydraulic module 2 includes a water supply pipeline 21, a circulating water pump 22, a water supply pipeline 24, a water supply tank 25 and a water supply pump 26. Both ends of the water supply pipeline 24 are connected to the water supply tank 25 and the water supply pipeline 21, and the water supply pump 26 is located in the water supply pipeline 24.

[0063] When the water pressure in the water supply pipeline 21 is too low, the water replenishment pump 26 is turned on, so that the water in the water replenishment tank 25 enters the water supply pipeline 21 through the water replenishment pipeline 24, thereby increasing the pressure of the water supply pipeline 21.

[0064] In some examples, such as Figure 4 As shown, a check valve 241 is provided on the water supply pipeline 24. The water inlet of the check valve 241 is connected to the water supply pump 26, and the water outlet is connected to the circulating water pump 22. This prevents the cooling water flowing out of the wet coil 12 or the second bypass pipeline 14 from entering the water supply tank 25 through the water supply pipeline 24, and ensures that all the cooling water flowing out of the wet coil 12 or the second bypass pipeline 14 enters the water supply pipeline 21.

[0065] In some examples, such as Figure 4 As shown, the water supply pipeline 24 is also provided with two manual ball valves 103. One manual ball valve 103 is located between the water supply tank 25 and the water supply pump 26, and the other manual ball valve 103 is located between the check valve 241 and the water outlet of the water supply pipeline 24. The two manual ball valves 103 are in a normally open state, and when the components such as the water supply pump 26 or the check valve 241 need to be repaired or replaced, the two manual ball valves 103 are closed.

[0066] When the pressure of the water supply pipeline 21 is too high and the expansion tank 23 alone cannot make the water supply pipeline 21 reach normal pressure, the water supply pipeline 21 needs to drain water to other components so that the water supply pipeline 21 can reach normal pressure. Figure 5 As shown, the hydraulic module 2 also includes a pressure relief pipeline 27. Both ends of the pressure relief pipeline 27 are respectively connected to the water outlet of the circulating water pump 22 and the water supply tank 25, and the pressure relief pipeline 27 has a pressure relief valve 271. When the pressure of the water supply pipeline 21 is too high, the pressure relief valve 271 will automatically open, so that part of the cooling water in the water supply pipeline 21 enters the water supply tank 25 through the pressure relief pipeline 27, thereby reducing the pressure of the water supply pipeline 21.

[0067] Among them, Figure 4 As shown, the water supply pipeline 21 is provided with a pressure sensor 211 . When the value measured by the pressure sensor 211 is too low, it indicates that the pressure in the water supply pipeline 21 is too low. At this time, the water replenishment pump 26 is turned on, so that the water replenishment tank 25 replenishes water to the water supply pipeline 21 .

[0068] In some examples, such as Figure 5 As shown, the water supply pipeline 21 is provided with a flow meter 212 , and the flow meter 212 can measure the flow in the water supply pipeline 21 , so as to monitor the flow of the water supply pipeline 21 in real time.

[0069] In some examples, the top of the water replenishment tank 25 also has an overflow port. When the water level in the water replenishment tank 25 is too high, water will flow out from the overflow port to avoid excessive pressure in the water replenishment tank 25.

[0070] In some examples, such as Figure 6 As shown, the hydraulic module 2 further includes a water supply pipeline 28. The water inlet of the water supply pipeline 28 is communicated with an external water source, and the water outlet is communicated with the water inlet of the circulating water pump 22.

[0071] When water is first supplied to the water supply pipeline 21, there is no cooling water in the dry coil 11 and the wet coil 12, so an external water source is required. A manual ball valve 103 is provided on the water supply pipeline 28. After the cooling water circulates in the data center, the cooling tower 1 and the hydraulic module 2, the manual ball valve 103 can be closed.

[0072] In some examples, such as Figure 7 As shown, the water outlet of the water supply pipeline 28 is also connected to the water supply tank 25. The water supply tank 25 has a liquid level sensor 251. An electric water supply valve 281 is provided between the water inlet end of the water supply pipeline 28 and the water supply tank 25. When the liquid level sensor 251 detects that the liquid level in the water supply tank 25 is too low, the electric water supply valve 281 opens, allowing the external water source to supply water to the water supply tank 25. When the liquid level sensor 251 detects that the liquid level in the water supply tank 25 reaches a normal value, the electric water supply valve 281 closes, and the external water source stops supplying water to the water supply tank 25.

[0073] In some examples, such as Figure 7 As shown, the water supply pipeline 28 is provided with a filter 282 to filter the external water source and prevent foreign matter from entering the water replenishment tank 25 and the water supply pipeline 21.

[0074] It should be noted that the hydraulic module 2 includes a plurality of normally open manual ball valves 103, which are located in a plurality of pipelines. When it is necessary to repair or replace components in the hydraulic module 2, the corresponding manual ball valve 103 can be closed to avoid water leakage.

[0075] In some examples, such as Figure 8 As shown, the cooling system further comprises a mounting frame 3, and the cooling tower 1 and the hydraulic module 2 are fixed to the mounting frame 3. Integrating the cooling tower 1 and the hydraulic module 2 in the mounting frame 3 can reduce the floor space of the cooling system.

[0076] In some examples, such as Figure 8 As shown, the mounting frame 3 includes an upper shell 31 and a lower shell 32. The dry coil 11, the first bypass pipeline 13 and the fan 15 are located inside the upper shell 31, and the wet coil 12, the second bypass pipeline 14, the spray assembly 16 and the hydraulic module 2 are located inside the lower shell 32. In this way, some components of the hydraulic module 2 can be prevented from being exposed to the outdoor environment for a long time, which improves the use environment of the components and reduces the failure rate and service life of the components due to environmental influences. The mounting frame 3 is arranged in two layers, which can facilitate the transportation of the cooling tower 1.

[0077] In some examples, such as Figure 8As shown, the upper housing 31 has a first inspection door 311, which is opposite to the dry coil 11. The lower housing 32 has a second inspection door 321, which is opposite to the wet coil 12. This makes it easy to inspect the dry coil 11 and the wet coil 12.

[0078] In some examples, the upper housing 31 has a plurality of first inspection doors 311, which are also opposite to the fan 15. The lower housing 32 has a plurality of second inspection doors 321, which are also opposite to the components in the hydraulic module 2, so as to facilitate maintenance of the hydraulic module 2.

[0079] In some examples, such as Figure 8 As shown, the hydraulic module 2 also has an electric control cabinet 29 , which is located on one side of the second inspection door 321 . The electric control cabinet 29 is used to control the operation of various components in the hydraulic module 2 .

[0080] In some examples, such as Figure 8 As shown, the mounting frame 3 also has a maintenance platform 33 and a maintenance ladder 34. The maintenance platform 33 is located between the upper shell 31 and the lower shell 32, and the staff can also climb up the maintenance platform 33 through the maintenance ladder 34 to maintain the components in the upper shell 31. In addition, the maintenance platform 33 can also serve as a rainproof shed for the lower shell 32.

[0081] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
