Abstract:
A compound heat exchanger comprising:a first heat exchanger comprising a plurality of first tubes, a pair of first header tanks connected to both ends of the first tubes, and a plurality of first fins connected between the first tubes, heat being exchanged between a first fluid contained in the first heat exchanger and cooling air blown to the first heat exchanger; a second heat exchanger comprising a plurality of second tubes, a pair of second header tanks connected to both ends of the second tubes, and a plurality of second fins connected between the second tubes, heat being exchanged between a second fluid contained in the second heat exchanger and cooling air blown to the second heat exchanger; and a side plate connecting the first and the second heat exchangers so that both heat exchangers are overlapped on each other in a flow direction of the cooling air, wherein: each of the pair of first header tanks includes a first tank cap closing a longitudinal end of the first header tank; each of the second header tanks includes a second tank cap closing a longitudinal end of the second header tank; at least one of the first and the second fins is connected to the side plate in heat conductive relation; at least one of the first and second tank caps is connected to the side plate in heat conductive relation; the side plate includes side walls formed at both sides along a longitudinal direction thereof and bent toward a direction opposite to the fins connected to the side plate and positioning walls formed at a center portion of the side plate; each tank cap includes a connecting portion extending therefrom; and the connecting portion is inserted and held between the side wall and the positioning wall of the side plate, and the tank cap is connected to the side plate by brazing.
