Title:
SUPERCOOLING DEVICE FOR IMPROVING SUPERCOOLING DEGREE BY MEANS OF BAFFLING EXPANSION, AND AIR-CONDITIONING UNIT
Document Type and Number:
WIPO Patent Application WO/2020/244206
Kind Code:
A1
Abstract:
Disclosed are a supercooling device for improving a supercooling degree by means of baffling expansion, and an air-conditioning unit. The supercooling device comprises a box body with a refrigerant flow channel, and further comprises a plurality of sets of baffle plates arranged on the refrigerant flow channel at intervals. Each set of baffle plates comprises at least one flash evaporation area gradually enlarged in a refrigerant flowing direction. According to the present application, a plurality of flash evaporation areas gradually enlarged in the refrigerant flowing direction are formed by means of gaps arranged between each set of baffle plates, such that when fluid impacts and passes through flash evaporation areas with rapidly increasing cross-sectional areas, the pressure of the fluid is rapidly reduced, a refrigerant is evaporated into a gas, and a supercooling effect is achieved, and due to the fact that the plurality of sets of baffle plates are arranged at intervals, a multi-stage flash evaporation effect is achieved, the pressure drop of fluid is gradually reduced, and the supercooling degree of a heat exchanger is gradually improved.
