Liquid receiver combined with liquid separator for refrigeration cycle and manufacturing method thereof

Abstract

The present invention relates to a liquid receiver combined with a liquid separator for a refrigeration cycle and a manufacturing method thereof; and more particularly, to a liquid receiver combined with a liquid separator for a vapor-compression refrigeration cycle and a manufacturing method thereof, by which manpower and working hours are reduced and the defect rate is reduced, thereby improving the productivity. The present invention comprises: a liquid separator (20), which includes a cover (21) with a cut portion of a refrigerant vapor suction conduit (18) and a cut portion of a refrigerant conduit (17) connected at the inside and outside thereof, respectively, facing each other, a cylindrical body (24) with the upper end coupled to the cover (21) in such a manner to surround the refrigerant vapor suction conduit (18), and a base plate (25) formed at the lower end of the cylindrical body (24); a liquid receiver (30), which has a main body (31) with the upper end being coupled to both ends of the cover, and a side wall (32) with an outlet opening (33) formed therein; ; and a heat pipe (40), which includes a plurality of main bodies (41) weld-bonded to the base plate (25) of the liquid separator, an evaporator (42) weld-bonded to the inside of the main body (31) of the liquid receiver, a condenser (43) weld-bonded to the inside of the liquid separator (20), and an exhaust pipe combined with a working fluid injection pipe (44) connected to the lower end of the main body (41) of each heat pipe in such a way to allow the heat pipe main bodies (41) to get interconnected in a communicating manner, whereby after a working fluid is injected to the heat pipe main bodies (41) an entrance of the exhaust pipe combined with the working fluid injection pipe (44) is cut and closed and the closure is then pushed inside the outlet opening (33).

Description

technical field [0001] The invention relates to a liquid receiver and gas-liquid separator for a refrigeration cycle and a manufacturing method thereof, in particular to a liquid receiver and a gas-liquid separator for a vapor compression refrigeration cycle and a manufacturing method thereof. Background technique [0002] As we all know, the refrigeration cycle performed by the refrigerator and the heat pipe is to use the refrigerant pipe to connect the compressor, the four-way valve, the indoor heat exchanger, the expansion valve, the outdoor heat exchanger and the four-way valve in sequence, and the refrigerant The steam suction conduit connects the four-way valve and the compressor. When the refrigerator is running, after the outdoor heat exchanger condenses the high-temperature and high-pressure refrigerant vapor compressed by the compressor, the indoor heat exchanger evaporates the refrigerant liquid. After the heat of evaporation is refrigerated, the low-temperature, ...

Problems solved by technology

[0004] However, in the refrigerating cycle, the flow rate of the refrigerant is appropriately adjusted by the expansion valve. If the refrigerant amount equivalent to evaporation in the evaporator is supplied to the evaporator, the state of the refrigerant after evaporation will be a dry saturated state, but the flow rate regulated by the expansion valve When the amount of refrigerant evaporated in the evaporator is greater than the optimum amount of refrigerant or the cooling load is reduced, the evaporation efficiency is reduced, the separation of refrigerant vapor and refrigerant liquid is poor, and it is sucked into the compressor, so there is a problem of preventing compressor damage. function problem
