Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/110638
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a heat exchanger which allows an improvement in the degree of freedom for arranging a gas-liquid separation unit with respect to a heat exchange unit. The heat exchanger comprises: a heat exchange unit that is composed of a plurality of plate members; a gas-liquid separation unit; and a connection unit (40) that connects the heat exchange unit and the gas-liquid separation unit. A discharge port (28) is formed in the outermost shell plate member (23b) disposed on the outermost side among the plurality of plate members. The connection portion has a side surface (41) fixed to the outermost shell plate member and an upper surface fixed to the gas-liquid separation unit. An internal flow path (44) is formed inside the connecting portion so as to extend from the side surface to the upper surface. A communication channel (F11) is formed between the side surface of the connection portion and the outermost shell plate member. The refrigerant discharged from the discharge port flows through the communication channel and the internal channel into the gas-liquid separation unit.
