According to the liquid cooling system replenishment operation process, the water quality of the liquid storage tank is tested to see whether the liquid meets the water quality requirements of the liquid replenished by the liquid cooling system.

[0043] When the liquid replenishing tank 140 needs to be replenished, the liquid suction end is connected to the external liquid storage tank, and the first electric valve 112, the liquid replenishing pump 114 and the fourth electric valve 160 are controlled to open through the control terminal.

[0044] When the automatic liquid replenishing system is used for automatic liquid replenishing of the liquid cooling system, the liquid supply end is connected to the liquid cooling system, and the second electric valve 118, the liquid replenishing pump 114 and the third electric valve 150 are controlled to open through the control terminal.
