HEAT EXCHANGE DEVICE FOR VEHICLES

An intercooler (3) is a two-stage water-cooled intercooler having a first core (5) and a second core (6). A condenser (32) for an air conditioner includes a water-cooled condenser (24) and an air-cooled condenser (27). A drive system electrical component (21) such as an inverter, the second core (6), and the water-cooled condenser (24) are cooled by a second cooling water circuit including a sub-radiator (18). Cooling is carried out by the second cooling water circuit including the sub-radiator (18). The sub-radiator (18) and the air-cooled condenser (27) are located in front of a main radiator (9).
