Abstract (en)
A heat exchanger 10 cools an air-conditioning refrigerant by means of cooling air. The heat exchanger 10 includes a first heat exchanger core 20 and a second heat exchanger core 30 placed forward and backward with respect to a flowing direction of the cooling air 60. The heat exchanger 10 further includes a first header tank 40 that is provided in a lower portion of the heat exchanger, and has two independent tank portions 43 and 44, one of the two tank portions located on a leeward side of the cooling air 60 being in communication with a refrigerant-inlet side of the second heat exchanger core 30, and the other one of the tank portions located on a windward side being in communication of a refrigerant-outlet side of the first heat exchanger core 20, the first header tank 40 introducing the refrigerant from the tank portion 43 located on the leeward side, and discharging the refrigerant from the tank portion 44 located on the windward side. The heat exchanger 10 also includes a second header tank 50 that is provided in an upper portion of the heat exchanger, that is in communication with a refrigerant-outlet side of the second heat exchanger core 30 and a refrigerant-inlet side of the first heat exchanger core 20, and that flows the refrigerant having passed through the second heat exchanger core 30 into the first heat exchanger core 20.
