Abstract
A compound type heat exchanger has a core part including a plurality of heat exchanging tubes and fins juxtaposed and alternately stacked. Header pipes are connected to the heat exchanging tubes at both ends of the heat exchanging tubes. A pseudo heat exchanging passage member having a substantially L-shaped or Z-shaped section is arranged in place of a specified heat exchanging tube of the heat exchanging tubes and a fin or both fins adjoining the specified heat exchanging tube. At the boundary of the pseudo heat exchanging passage member, the core part is divided into two parts, defining an oil cooler unit and a condenser unit. Owing to the provision of the pseudo heat exchanging passage member in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.
