Abstract

The invention discloses a liquid circular cooling system and a protection method and device thereof. The method comprises the steps that in the state that power of a cooled device outputs, and a power switch of a pump is closed, the hydraulic value at one preset position point of a liquid circulation pipeline in the liquid circular cooling system is obtained; whether the hydraulic value exceeds the first allowable range or not is judged; and if the hydraulic value exceeds the first allowable range, a shutdown protection instruction is sent. Whether the faults such as blockage or leakage or fracture of the liquid circulation pipeline of the liquid circular cooling system or abnormal running of the pump of the liquid circular cooling system or not is monitored online, and maintenance can be conducted in time after the faults happen.

Description

technical field [0001] The present invention relates to the technical field of liquid cooling, more specifically, to a liquid circulation cooling system and its protection method and device. Background technique [0002] figure 1 It shows a typical liquid circulation cooling system, which mainly consists of cooler (1), filter (2, 3), liquid circulation pipeline (4), liquid expansion tank (5), upper valve (6), lower Composed of valve (7) and pump (8), its working principle is: after the cooling liquid is cooled by the cooler (1), it is transported to the cooled equipment (9) by the pump (8) along the liquid circulation pipeline (4), After exchanging heat with the equipment to be cooled (9), it flows back to the cooler (1) along the liquid circulation line (4) for cooling, so as to realize recycling. Among them, the valves (6, 7) are used to realize the cut-off function; the filters (2, 3) are used to filter out impurities in the cooling liquid; the liquid expansion tank (5)...
