A heat pipe internal circulation type secondary refrigerant loop server cabinet heat dissipation system

Abstract

The invention discloses a cooling system for server cabinets with a heat pipe internal circulation secondary refrigerant loop circuit, which includes a machine room unit and a refrigerant supply and return fluorine unit. The refrigerant supply and return fluorine unit includes a circulating power unit and a cooling unit. The circulating power unit passes through The first refrigerant loop and the machine room unit form a closed cycle, and the second refrigerant loop forms a closed cycle with the cooling unit. The invention realizes the short-distance accurate delivery of cold air in the cabinet, and solves the problems of local overheating and hot spots in the server cabinet; at the same time, the natural cooling measures are used, the heat exchange temperature difference is large, the efficiency is high, and the active anti-condensation is adopted, which has high reliability, low power consumption, The characteristics of low noise meet the concept of energy saving and environmental protection.

Description

technical field [0001] The invention relates to a heat dissipation system for a server cabinet, in particular to a heat pipe internal circulation type secondary refrigerant loop server cabinet heat dissipation system. Background technique [0002] With the continuous increase of high-density cabinets in the IDC Internet data center computer room, the integration of equipment is getting higher and higher, and the processing capacity is gradually increasing, but the power consumption of the equipment is also increasing, resulting in more heat generated by the equipment in the cabinet. According to statistics, at present, the cabinet servers in large-scale IDC computer rooms in China generate a lot of heat, and basically run 8760h throughout the year. It accounts for about 40%~50% of the overall energy consumption of the data center. [0003] Traditional data room air supply methods include floor air duct air supply, hot and cold aisle isolation air supply, and whole room cool...
