Super-cooling device of refrigerating system

Abstract

The invention provides a super-cooling device of a refrigerating system. The super-cooling device comprises a shell, a refrigerant inlet, a refrigerant outlet, a flow dividing cavity, a super-coolingcavity, flow dividing pipes and a flow collecting cavity. The shell comprises the flow dividing cavity, the super-cooling cavity and the flow collecting cavity, the refrigerant inlet communicates withthe flow dividing cavity, the flow dividing pipes traverse the super-cooling cavity to communicate with the flow dividing cavity and the flow collecting cavity, throttle spray holes communicating with the flow dividing pipes and the super-cooling cavity are formed in the flow dividing pipes, the flow dividing cavity communicates with the flow collecting cavity through overflow holes, and the refrigerant outlet communicates with the flow collecting cavity and outputs super-cooled refrigerant. After the refrigerant is liquidized in a condenser and before the refrigerant enters a throttle mechanism, the liquid-state refrigerant is re-cooled into super-cooled liquid, the super-cooling degree of the refrigerant can be further improved, and the refrigerating amount of the refrigerating system can be increased. Thus, when a piping of a data center air conditioner is long or the altitude difference of the data center air conditioner is large, along with increase of pressure losses, a system has the enough super-cooling degree to prevent the refrigerant from vaporizing, it is guaranteed that the refrigerant before entering a throttle element of an evaporator is in a super-cooled state, theuse occasions of the data center air conditioner system are increased, and the refrigerating performance of the data center air conditioner system is improved.

Description

technical field [0001] The invention relates to the technical field of server cooling, in particular to a refrigeration system supercooling device. Background technique [0002] With the rapid development of the electronic information industry, the development of data centers has also entered a new stage. The reliability of the air conditioning system directly affects the safety of the data center. At present, most data center refrigeration and air conditioners use compression refrigeration cycles. Because of the factors of refrigerant vaporization and refrigeration energy efficiency in the refrigeration system, traditional precision air conditioners usually require shorter piping lengths, which limits the use of air conditioners. When some installation conditions cannot meet the piping length requirements, traditional data center air conditioners cannot be applied. Contents of the invention [0003] In order to overcome the problems in the prior art, the invention provi...
