[0025] The pipeline between the stop valve 5 and the fine filter 6 has two bypasses A and B. The bypass A is connected with the inlet of the stop valve 4 17, the outlet of the stop valve 4 17 is connected with the inlet of the deionization device 18 through a pipeline, the outlet of the deionization device 18 is connected with the inlet of the ball valve 2 19 through a pipeline, the outlet of the ball valve 2 19 is connected with the inside of the liquid storage tank 1 through a pipeline; the bypass B is connected with the inlet of the ball valve 3 20, the outlet of the ball valve 3 20 is connected with the inside of the liquid storage tank 1 through a pipeline.

[0026] In the embodiment, the photoelectric liquid level sensor 28, the temperature sensor 29 and the pressure sensor 2 30 are installed in the liquid storage tank 1 and are used to detect the liquid level, the temperature and the pressure of the liquid storage tank 1 respectively. The electric heating device 27 is installed in the liquid storage tank 1 and is used to heat the cooling liquid in the liquid storage tank 1. The automatic exhaust valve 26 is installed on the top of the liquid storage tank 1 and is used to realize exhaust. The liquid discharge valve 23 is installed on the bottom of the liquid storage tank 1 and is used to realize liquid discharge.

[0027] In the embodiment, the outlet of the air pump 22 is connected with the inlet of the electromagnetic valve 4 21 through a pipeline, the outlet of the electromagnetic valve 4 21 is connected with the pipeline between the outlet of the electromagnetic valve 1 7 and the inlet of the ball valve 1 8 through a bypass pipeline, and the air pump 22 is used to assist the liquid storage tank 1 to discharge liquid.

[0028] In the embodiment, the pressure sensor 1 24 is installed in the pipeline between the outlet of the ball valve 1 8 and the inlet of the load 9 and is used to detect the pressure of the cooling liquid entering the load 9.

[0029] The working process of the liquid cooling system in the embodiment is as follows:

[0030] When the ambient temperature is 10℃-55℃, the flow direction of the cooling liquid is: the liquid storage tank 1→the stop valve 1 2→the primary filter 3→the water pump 4→the stop valve 2 5→the fine filter 6→the electromagnetic valve 1 7→the ball valve 1 8→the load 9→the stop valve 3 10→the electromagnetic valve 2 11→the plate heat exchanger 12→the liquid storage tank 1. The cooling liquid flowing out of the load 9 exchanges heat with the refrigerant flowing through the first group of flow channels and the second group of flow channels of the plate heat exchanger 1 1 and then enters the liquid storage tank 1, is filtered by the primary filter 3, is pressurized by the water pump 4, is filtered by the fine filter 6 and is sent to the load to complete the circulation.

[0031] When the ambient temperature is -40℃ to 10℃, the flow direction of the cooling liquid is: liquid tank 1→ stop valve 2→ primary filter 3→ water pump 4→ stop valve 5→ fine filter 6→ electromagnetic valve 7→ ball valve 8→ load 9→ stop valve 10→ electromagnetic valve 13→ heat exchanger 14→ liquid tank 1. The cooling liquid from the load 9 enters the liquid tank 1 again through the heat exchanger 14, is filtered through the primary filter 3, is pressurized through the water pump 4, is filtered through the fine filter 6, and is sent to the load to complete the circulation. The condensing fan 16 of the heat exchanger 14 forcibly convects ambient air to take away the heat of the cooling liquid. The electromagnetic bypass regulating valve 15 bypassing the heat exchanger 14 facilitates the bypass control of the cooling liquid at low temperature to control the supply liquid temperature and precision.

[0032] When the liquid cooling system is working, in addition to completing the above-mentioned working process of the liquid cooling system, when the supply liquid flow and pressure need to be adjusted, since the load supply liquid flow and pressure change with the need, the liquid cooling system supply liquid flow and pressure need to be adjusted at any time. A and B two paths between the stop valve 5 and the fine filter 6 and the ball valve 8 are adopted to control the ball valve 8, the ball valve 2 19 and the ball valve 3 20 as the regulating devices of the bypass flow of the cooling liquid to realize the adjustment of the supply liquid flow (flow sensor 25 flow feedback display) and the supply liquid pressure (pressure sensor 1 24 pressure feedback display). In addition, during the adjustment, the bypass flow of the ball valve 2 19 is adjusted by opening the stop valve 4 17 first. When the required pressure and flow are not reached, the bypass flow of the ball valve 3 20 and the ball valve 8 is adjusted in turn until the required flow and pressure are reached. In this way, the cooling liquid can also be circulated through the deionization device 18 to ensure the water quality requirement of the supply liquid of the liquid cooling system.

[0033] The liquid cooling system generally uses a manual opening liquid discharge valve to discharge liquid. The liquid remaining in the pipeline cannot be completely discharged. In the embodiment, a C path is arranged between the outlet of the electromagnetic valve 7 and the inlet of the ball valve 8. The C path is connected with the electromagnetic valve 4 21 and the air pump 22 in sequence. When the liquid is discharged, the liquid discharge valve 23 is opened, the electromagnetic valve 4 21 and the air pump 22 are opened, and the electromagnetic valve 7 is closed. The liquid is discharged through the connected outlet pipeline of the liquid discharge valve 23. This method can conveniently and effectively discharge the cooling liquid.

[0034] In the embodiment, the photoelectric liquid level sensor 28 is used to realize the low liquid level alarm of the solution tank. The pressure sensor 2 30 is used to sense the pressure to realize the liquid level display through the control. The temperature sensor 29 is used to sense the temperature to realize the temperature display through the control.

[0035] In the embodiment, the electric heating device 27 is arranged in the liquid tank 1 to realize the preheating of the heat exchange system.

[0036] In the embodiment, the front end of the primary filter 3 is provided with a stop valve 2, the outlet end of the water pump 4 is provided with a stop valve 5, the two ends of the deionization device 18 are provided with a stop valve 4 and a ball valve 2 respectively, and the two ends of the fine filter 6 are provided with a stop valve 5 and a solenoid valve 1 respectively, so that the primary filter 3 and the water pump 4 are convenient to maintain and replace, the core of the deionization device 18 is convenient to maintain and replace, and the filter core of the fine filter 6 is convenient to maintain and replace.
