Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/040297
Kind Code:
A1
Abstract:
A heat exchanger (100) and a refrigeration cycle system. The heat exchanger comprises: a first refrigerant inlet/outlet (111), a second refrigerant inlet/outlet (112), and a plurality of heat exchange pipes (140); according to the second refrigerant inlet/outlet (112), under the condition that the heat exchanger (100) serves as an evaporator, a refrigerant flows in from the first refrigerant inlet/outlet (111) and flows out from the second refrigerant inlet/outlet (112); under the condition that the heat exchanger (100) serves as a condenser, the refrigerant flows in from the second refrigerant inlet/outlet (112) and flows out from the first refrigerant inlet/outlet (111); the plurality of heat exchange pipes (140) are communicated with the first refrigerant inlet/outlet (111) and the second refrigerant inlet/outlet (112); under the condition that the heat exchanger (100) is used as the evaporator, N heat exchange flow paths (130) are formed by the plurality of heat exchange pipes (140); and under the condition that the heat exchanger (100) is used as the condenser, M heat exchange flow paths (130) are formed by the plurality of heat exchange pipes (140), wherein 30％≤M/N≤70％. The overall pressure loss of the heat exchanger (100) is reduced to the greatest extent, and the heat exchange efficiency is improved, such that the energy efficiency of a product is improved.
