Heat-pipe internal-circulation secondary refrigerant loop server cabinet heat radiation system

Abstract

The invention discloses a heat-pipe internal-circulation secondary refrigerant loop server cabinet heat radiation system which comprises a machine room unit and a refrigerant fluorine supplying and returning unit, the refrigerant fluorine supplying and returning unit comprises a circulating power unit and a cooling unit, and the circulating power unit forms closed circulation with the machine room unit through a first refrigerant loop and forms closed circulation with the cooling unit through a second refrigerant loop. The system realizes short-distance accurate transportation of cool air of a cabinet and solves problems of local overheat and existence of hot spots of the server cabinet ; and, at the same time, a natural cooling measure is used so that a heat exchange temperature difference is huge and efficiency is high, and active anti-condensation is adopted so that the system has the advantages of high reliability, low power consumption and low noise and satisfies an energy saving and environment protecting concept.

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...
