Title:
HEAT EXCHANGER, OUTDOOR UNIT, AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/234956
Kind Code:
A1
Abstract:
A heat exchanger according to the present disclosure comprises: a main heat exchange unit that exchanges heat between air and refrigerant and condenses the refrigerant; a supercooling heat exchange unit that exchanges heat between the refrigerant that has passed through the main heat exchange unit and air to supercool the refrigerant that has passed through the main heat exchange unit; and a connection pipe that connects the main heat exchange unit and the supercooling heat exchange unit and allows the refrigerant to pass through. The connection pipe connects the refrigerant outflow side of the main heat exchange unit to the refrigerant inflow side of the supercooling heat exchange unit so that the main heat exchange unit and the supercooling heat exchange unit allow the refrigerant from the outside to flow into the downstream side in the air flow direction and flow out from the upstream side in the air flow direction to form a countercurrent in which the air flow and the refrigerant flow face each other, during condensation in the main heat exchange unit.
