Claim 11:
12. The method according to claim 10, wherein the cooling system further comprises a first three-way valve and a second three-way valve, and the step of performing coolant adding operation for the coolant tank comprising:
switching the first three-way valve and the second three-way valve by the control unit, and forming a fluid loop including an external coolant source, the first three-way valve, the injection pump, the second three-way valve, and the coolant tank in sequence; and
turning on the injection pump to automatically add coolant to the coolant tank until the liquid level of the coolant tank reaches the upper liquid level threshold, wherein the control unit is configured to then turn off the injection pump, and switch the first three-way valve and the second three-way valve to form a fluid loop including the coolant tank, the first three-way valve, the injection pump, the second three-way valve, and the liquid cooling pipeline in sequence.
