Title:
HEAT EXCHANGER, REFRIGERATION CYCLE SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/040282
Kind Code:
A1
Abstract:
Provided is a heat exchanger (100), comprising: a heat exchanger (100) body provided with a first refrigerant inlet/outlet (111), a second refrigerant inlet/outlet (112) and a plurality of heat exchange branches (120), wherein when the heat exchanger (100) serves as an evaporator, the first refrigerant inlet/outlet (111) is used for liquid feeding and the second refrigerant inlet/outlet (112) is used for liquid discharging, and when the heat exchanger (100) serves as a condenser, the first refrigerant inlet/outlet (111) is used for liquid discharging and the second refrigerant inlet/outlet (112) is used for liquid feeding; a second liquid distributor (212) provided with a flow convergence port (222) communicated with the first refrigerant inlet/outlet (111), and a plurality of liquid distribution ports (221) communicated with the plurality of heat exchange branches (120) one by one; and a first check valve (311) of which the flow direction is limited in such a way that said valve is opened when the heat exchanger (100) serves as the evaporator, and is blocked when the heat exchanger (100) serves as the condenser so that the second liquid distributor (212) stores liquid. The heat exchanger (100) uses the liquid distributor (212) to store part of the refrigerant. Further provided are a refrigeration cycle system and an air conditioner.
