Abstract: Disclosed is a liquid cooling cabinet equipment including a load device, a power supply device for supplying power to the load device and a liquid cooling system, which includes a liquid storage tank, a primary fluid loop pipeline, a secondary fluid loop pipeline connected to the liquid storage tank, a heat exchanger, a circulation motor, a power sensor, and a control device. The circulation motor drives a coolant in the liquid storage tank to circulate in the secondary fluid loop pipeline. After exchanging heat with the load device, the coolant in the secondary fluid loop pipeline exchanges heat with another coolant in the primary fluid loop pipeline through the heat exchanger. The control device controls a rotation speed of the circulation motor based on an output power of the power supply device sensed by the power sensor to adjust a flow of the coolant in the secondary fluid loop pipeline.
