Secondary water-loop server cabinet cooling system

Abstract

Disclosed in the invention is a secondary water-loop server cabinet cooling system. Heat radiation is carried out by using a liquid conducting method. The cooling system comprises an internal circulating system, an external circulating system, and a control system. An internal circulating loop secondary refrigerant absorbs heat from a server core component by a server heat pipe assembly and then flows to an intermediate heat exchanger to carry out heat exchange with an external circulating flow for heat radiation; after the external circulating flow absorbs heat, the heat is dissipated to the external environment by a cooling tower, thereby realizing the natural heat radiation process. And precise temperature control and energy-saving running of the cooling system can be realized by the control system. According to the invention, no compressor refrigerating system is needed. Effective heat radiation of the server is realized by using a complete natural cooling way; and the energy saving effect is obvious. Meanwhile, a heat pipe indirect cooling scheme is used for the server chip and the water can not enter the inside of the server directly, so that compared with other direct liquid-cooled schemes, the provided scheme enables security of the server to be improved.

Description

technical field [0001] The invention relates to the technical field of cooling systems for equipment in a computer room, in particular to a secondary water loop cooling system for server cabinets. Background technique [0002] The equipment in the equipment room and the base station generates a lot of heat during operation. In order to maintain the normal operating temperature of the equipment, the equipment room needs to be equipped with relevant equipment to run all year round to dissipate heat from the equipment in the equipment room. With the rapid development of the information industry, the speed of construction of computer rooms and base stations has increased, the number of servers has increased significantly, and their power consumption and heat dissipation have also continued to increase. The demand for cooling equipment in computer rooms has also increased, and its energy-saving performance has become increasingly The more widely concerned by manufacturers and use...
