Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/129180
Kind Code:
A1
Abstract:
A heat exchanger has a first heat exchanging unit and a second heat exchanging unit disposed vertically, and when the heat exchanger functions as a condenser, refrigerant flows through the first heat exchanging unit and then flows through the second heat exchanging unit. An intermediate header unit that communicates with the first heat exchanging unit and the second heat exchanging unit drains at least some refrigerant that has passed through a first heat transfer tube group on the windward side of the first heat exchanging unit to a fourth heat transfer tube group on the leeward side of the second heat exchanging unit. In addition, the intermediate header unit causes at least some of the refrigerant that has passed through the second heat transfer tube group on the leeward side of the first heat exchanging unit to flow into a third heat transfer tube group on the windward side or the fourth heat transfer tube group on the leeward side of the second heat exchanging unit.
