PROBLEM TO BE SOLVED: To suppress lowering of a heat exchange efficiency of a condenser core part in a heat exchanger wherein the condenser core part and a radiator core part are integrated. SOLUTION: In a side plate 4 coupling two core parts 2 and 3, notch parts 41a are formed in the end parts on the sides of radiator core tanks 5 and 6. Since a route of heat conduction in a portion wherein the amount of heat conduction is the largest is cut off thereby, the heat conduction can be interrupted effectively. Accordingly, lowering of a heat exchange efficiency in the condenser core part 2 can be suppressed. Moreover, a plurality of cut parts 41 are formed in portions corresponding to a gap between the two core parts 2 and 3 and, therefore, a jig for positioning tubes 21 and 31 of the two core parts and cooling fins 22 and 32 thereof can be fitted to the cut parts 41 at the time when cores are assembled. Accordingly, the fitting properties of the tubes 21 and 32 and the cooling fins 22 and 32 are improved. |
