ABSTRACT:
A compound type heat exchanger has a core part including a plurality of heat exchanging pipes and fins juxtaposed and alternately stacked into a lamination. Header pipes are connected to both ends of the pipes. Partition walls are provided in the header pipes. At a boundary of the partition wall and a spatial part, the core part is divided into two parts providing an oil cooler unit on one hand and a condenser unit on the other hand. The spatial part is defined in the core part, corresponding to the intermediate portion between the partition walls in the header pipe. Owing to the provision of the spatial part in the core part, heat conduction from the oil cooler unit to the condenser unit can be suppressed.
