Liquid separation device and air conditioner comprising liquid separation device

Abstract

The invention provides a liquid separation device and an air conditioner comprising the liquid separation device. The liquid separation device comprises a first liquid collection tube and a liquid separation tube, wherein the two end faces of the first liquid collection tube are closed; a plurality of tube wall outlets are formed in a tube wall of the first liquid collection tube in a length direction; the liquid separation tube is arranged in the first liquid collection tube; one end of the liquid separation tube stretches out of one end face of the first liquid collection tube; and the liquid separation tube is eccentrically arranged in the first liquid collection tube. With the adoption of the technical scheme, the liquid separation tube is eccentrically arranged in the liquid collection tube, so that a distance between the liquid separation tube and an inner wall of the liquid collection tube is increased, a larger flowing space is provided for gas and liquid phase refrigerants flowing out of the liquid separation tube, the liquid separation stability of the gas and liquid phase refrigerants is improved, the gas and liquid phase refrigerants entering the liquid collection tube are more uniformly distributed into microchannel tubes, and furthermore a utilization ratio of a heat exchange area of a microchannel heat exchanger is increased.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a liquid distributing device and an air conditioner including the liquid dispensing device. Background technique [0002] At present, the mainstream of heat exchangers on air conditioner heat exchangers is still finned copper tube heat exchangers. Finned copper tube heat exchangers have problems such as high cost, poor resistance to electrical corrosion, and complicated welding of liquid distribution pipe / collection pipe components. [0003] The micro-channel heat exchanger adopts flat tube enhanced heat transfer technology. It is a flat tube heat exchanger made of all-aluminum material. It has the advantages of low cost, strong resistance to electrical corrosion, and simple structure of the liquid distribution pipe / collection pipe assembly. Moreover, microchannel heat exchangers have been used in single coolers and have been used in automotive air conditioners f...

AI Technical Summary

Problems solved by technology

According to the results of the matching test, the microchannel heat exchangers of major domestic manufacturers generally have the problem of uneven liquid separation of the microchannel tubes during high-frequency refrigeration operation. Under the conditions of use, if the microchannel tubes in the heat exchanger are unevenly distributed, the flow rate of refrigerant in different tubes will be uneven, and the flow rate in the tubes will evaporate quickly, and the superheat at the outlet of the tubes will be high; the flow rate in the tubes will be too high. Evaporation is not complete, resulting in a small outlet superheat, and even contains liquid
