HEAT EXCHANGER, REFRIGERANT CYCLE DEVICE, AND HOT WATER SUPPLY APPARATUS

WIPO Patent Application WO/2024/014495

A1

Provided are a heat exchanger capable of ensuring heat exchange performance even if there is a difference in pressure between two fluids when the two fluids are flowing in, and a refrigerant cycle device and a hot water supply apparatus employing the same. A first heat exchanger (100) comprises a first heat transfer plate (110) and a second heat transfer plate (120). The second heat transfer plate includes a second flow-through port (121a, 121b), a second through-hole (122a, 122b), a second heat transfer region (123), and a second connecting portion (125a, 125b). The second flow-through port introduces/discharges a second fluid having a lower boiling point than a first fluid. The first fluid passes through the second through-hole in a thickness direction. The second fluid passes through the second heat transfer region while exchanging heat with the first fluid. The second connecting portion has one end connected to the second flow-through port and another end connected to the second heat transfer region. The second flow-through port is formed in a position opposite to the second heat transfer region across the second through-hole. The second connecting portion is formed so as to encircle the outside of the second through-hole, and is provided with second protruding portions (127a, 127b).
