VEHICLE HEAT EXCHANGER

WIPO Patent Application WO/2022/092715

A1

A heat exchanger comprises: a plurality of first stacked plates forming a condensing portion in which a refrigerant is condensed; a receiver container for storing the refrigerant which has passed through the condensing portion; a plurality of second stacked plates forming a subcooling portion in which the refrigerant is cooled; and an intermediate plate interposed between the plurality of first stacked plates and the plurality of second stacked plates, and provided with respective through-holes through which the refrigerant and a coolant respectively flow. The plurality of second stacked plates form a refrigerant bypass flow path for bypassing, to the receiver container, the refrigerant which has passed through the condensing portion and the through-hole of the intermediate plate, the refrigerant bypass flow path being formed into a sealed passage by means of the male-female coupling of a male flange and a female flange respectively provided on the second stacked plates adjacent to each other. The plurality of second stacked plates have respective through-holes formed through which the refrigerant which has been returned from the receiver container flows, wherein the refrigerant bypass flow path and the through-holes are disposed so as to be adjacent to each other in the transverse direction.
