PROBLEM TO BE SOLVED: To suppress thermal effect on a supercooling part of a condenser for air conditioning in engine high load, in an integration type heat exchanger formed by integrating the condenser for air conditioning having a supercooling part with an engine cooler. SOLUTION: Tubes 24 are laminated on a radiator core part 21 of a cooler 20 for an engine. Widths of tubes 24A out of the tubes 24 positioned to be opposed to the supercooling part 50 of the condenser 30 for air conditioning are narrower than widths of the tubes 24 disposed to other positions. Since the heat is made thereby unsusceptible to transmission from the tubes 24A, through which engine cooling water flows, to the tubes 24 adjacent to the tubes 24A, the thermal effect on the supercooling part 50 is suppressed.
