Title: PARTIAL IMMERSION LIQUID-COOLING SYSTEM FOR COOLING SERVER
Abstract:
Disclosed is a partial immersion liquid-cooling system for cooling a server, comprising a server chassis, a chassis cover, heat radiating fins, a heat radiator, an oil collecting tank and an oil pump. The chassis cover covers the chassis to form a closed cavity; a main board connected with a chip is disposed in the cavity; an oil inlet and an oil outlet communicated with the cavity are respectively formed at two sides of the chassis; a liquid dividing box is disposed at one side closed to the oil inlet in the chassis; the oil outlet is sequentially communicated with the heat radiator, the oil collecting tank and the oil pump by means of an oil pipeline, and the other end opening of the oil pipeline is communicated with the oil inlet to form a closed circulating loop; the chassis is filled with a liquid working medium, and the main board, the chip and the heat radiating fins are immersed in the liquid working medium. The oil outlet is under the liquid level of the liquid working medium. The invention is high in heat transfer efficiency, achieves the effects of energy saving and environmental protection, can effectively implement local flowing cooling of heating elements such as a chip, and can easily uniform the temperature, so that heat radiating of the heating chip can be more effective, and meanwhile the cost is reduced.
