Abstract
A compound type heat exchanger has an oil cooler unit and a condenser unit integrated with each other. Both of the units have a plurality of heat exchanging pipes and fins juxtaposed and alternately stacked into a lamination, in common. At both ends of the lamination in the longitudinal direction of the pipes, they are connected with header pipes. At a boundary between the units, the heat exchanger includes partition walls arranged in the header pipes and a pseudo heat exchanging passage member interposed in the lamination. Further, at least either one of two fins adjoining the pseudo heat exchanging passage member on the side of the oil cooler unit and also on the side of the condenser unit is joined to the pseudo heat exchanging passage member, while the other fins are joined to the pipes.
