Beschreibung
Zusammenfassung:	Cooling performance is secured by reducing a compression loss when a high-pressure gas refrigerant is allowed to flow without heat exchange on cooling in a vehicle interior heat exchanger. In the vehicle interior heat exchanger, an upstream header and a downstream header are communicated and connected with the same end side of the refrigerant circulation tubes of an upstream tube group and a downstream tube group where the refrigerant circulation tubes are stacked. Internal spaces of the upstream header and the downstream header are communicated and connected with each other via communication holes in the boss portions of the connecting member. In the vehicle interior heat exchanger, the total opening area of the communication holes is set such that the percentage thereof, with respect to the total opening area of the channel on the uppermost stream side of the upstream tube group, is in the range of 38% to 93%.
