Fluorine-pump internal-circulation secondary refrigerant loop server cabinet heat radiation system

Abstract

The invention discloses a fluorine-pump internal-circulation secondary refrigerant loop server cabinet heat radiation system, which comprises a machine room unit and a refrigerant fluorine supplying and returning unit, wherein 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 fluorine-pump internal-circulation secondary refrigerant loop server cabinet heat radiation system achieves short-distance accurate transport of cool air of a cabinet, and solves problems of local overheat and existence of hot spots of the server cabinet; meanwhile, a natural cooling measure is adopted so that heat exchange temperature difference is huge and efficiency is high; and active condensation prevention 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 involves a server cabinet heat dissipation system, especially involving a circular two -time refrigerant circuit server cabinet cooling system in the fluorine pump. Background technique [0002] With the increasing increase of high -density cabinets in the IDC Internet data center, the integration of equipment is getting higher and higher, and the processing capacity has gradually increased.According to statistics, at present, the cabinet server in the large IDC machine room is large in heat, and it is basically running 8760h throughout the year. For the machine room that does not adopt a fresh air, it is necessary to cool the air -conditioning system throughout the year.It accounts for about 40%to 50%of the overall energy consumption of data machine rooms. [0003] Traditional data machine room air supply methods include bottom panel air ducts, hot and cold channels, and air supply air supply and whole room refrigeration and air supply.Large,...
