Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/130834
Kind Code:
A1
Abstract:
A heat exchanger according to an embodiment has a plurality of heat exchange tubes and headers. The plurality of heat exchange tubes each have formed therein a refrigerant flow passage through which a refrigerant flows. The headers are provided at end sections of the heat exchange tubes. The plurality of heat exchange tubes each include first and second upstream-side heat exchange tubes disposed in said order side by side in a first direction, and first and second downstream-side heat exchange tubes disposed in said order side by side in the first direction. At least one of the headers comprises an inner plate body to which the heat exchange tubes are connected, an outer plate body disposed facing the inner plate body, and intermediate plate bodies provided between the inner plate body and the outer plate body. A first transition flow passage and a second transition flow passage are formed in the intermediate plate bodies. The first transition flow passage allows the refrigerant flow passage of the first downstream-side heat exchange tube to communicate with the refrigerant flow passage of the second upstream-side heat exchange tube. The second transition flow passage allows the refrigerant flow passage of the second downstream-side heat exchange tube to communicate with the refrigerant flow passage of the first upstream-side heat exchange tube.
