Wherein, the extrinsic cycle of liquid cooling system indicates: the working fluid flows out from the device to be cooled 100, flows into the heat sink 200 through the liquid cooling system, and flows into the device to be cooled 100 through the liquid cooling system after being cooled by the heat sink 200, and the process is repeated, as indicated by the solid arrows in fig. 10. The internal circulation of the liquid cooling system refers to: the working liquid flows out from the device to be cooled 100, flows into the liquid cooling system through the first liquid inlet interface 511, sequentially flows into the heater 4 through the water outlet of the water pump 1 and the three-way control valve 532, is heated by the heater 4, and then flows into the device to be cooled 100 from the second liquid outlet interface 541, and circulates in this way, as shown by the flow direction of the working liquid indicated by the hollow arrow in fig. 10, until the temperature of the working liquid rises to a set temperature (for example, 5 ℃), and then stops circulating. In winter in northern areas, after the liquid cooling system is connected between the device to be cooled 100 and the heat dissipation device 200 due to low outdoor temperature, when the whole cooling circulation system starts to work (i.e., starts up), the device to be cooled 100 does not start working formally, and no heat or a small amount of heat is generated, so that the temperature of the working fluid flowing out of the device to be cooled 100 is low, and the heat dissipation device 200 cannot be started to perform heat dissipation when the working fluid with low temperature flows into the heat dissipation device 200.

Therefore, the three-way control valve 532 is provided in this embodiment, the three-way control valve 532 is used to communicate the second valve port and the third valve port, and block the first valve port to perform internal circulation of the liquid cooling system, the working liquid is preheated when the whole cooling circulation system is just started until the temperature of the working liquid is raised to a set temperature, at this time, the heat sink 200 is started to operate, and the liquid cooling system stops the internal circulation; meanwhile, the three-way control valve 532 is used for communicating the first valve port and the second valve port, and blocking the third valve port to perform external circulation of the liquid cooling system, so as to cool and dissipate the heat of the device to be cooled 100.

Optionally, as shown in fig. 1 to 9, the liquid cooling system further includes a base 19, and the water pump 1 and the expansion tank 2 are detachably fixed on the base 19.

The base 19 can be arranged in the liquid cooling system or the base 19 can be omitted, and when the liquid cooling system is assembled in a cabinet of high-power equipment, if the base 19 is not arranged in the liquid cooling system, the water pump 1 and the expansion tank 2 need to be fixed on a bottom plate or an inner wall of the cabinet in the cabinet. In the embodiment, the base 19 is arranged in the liquid cooling system, so that the structures of the water pump, the expansion tank 2 and the like can be fixed on the base 19 in the process of assembling the liquid cooling system, then the whole liquid cooling system and the base 19 are placed into the cabinet of the high-power equipment and fixed together, and the assembly of the liquid cooling system in the cabinet can be completed, so that the operation is simple and convenient, and the efficiency is high.

Optionally, the liquid cooling system further includes a junction box 12 and a second bracket 13, the junction box 12 is detachably fixed on the second bracket 13, and the water pump 1, the three-way control valve 532 and the heater 4 are electrically connected to the junction box 12. Thus, the independent control junction box 12 is adopted, so that the liquid cooling system can be externally arranged outside the device to be cooled 100 to independently control the operation of the liquid cooling system.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
