Document Type and Number:
WIPO Patent Application WO/2019/176089
Kind Code:
A1
Abstract:
The present invention provides a heat exchanger according to an embodiment comprising: a first header, a second header, and a plurality of heat-exchanging tubes. The plurality of heat-exchanging tubes comprises a first heat-exchanging tube and a second heat-exchanging tube. A gas-liquid two-phase refrigerant in which a liquid-phase component is a major component flows through the first heat exchanging tube. The second heat exchanging tube communicates with the first heat exchanging tube and a gas-liquid two-phase refrigerant in which a gas-phase component is a major component flows through the second heat exchanging tube. The second heat exchanging tube comprises an upper second heat exchanging tube and a lower second heat exchanging tube. The upper second heat exchanging tube is disposed above the first heat exchanging tube. The lower second heat exchanging tube is disposed below the first heat exchanging tube.
