HEAT EXCHANGE APPARATUS OF VEHICLE

A heat exchange apparatus (1) of a vehicle includes a coolant circuit (40, 43), to which a water pump (45), an EGR cooler (17) in which exhaust gas flowing through an EGR passage (13) and a coolant exchange heat, an oil cooler (25) in which engine oil and the coolant exchange heat, and an ATF warmer (35) in which an automatic transmission fluid as a hydraulic fluid of an automatic transmission (30) and the coolant exchange heat are connected, between a water jacket exit (22) and a water jacket entry (21) of an internal combustion engine (10). In the coolant circuit (40, 43), the oil cooler (25) and the ATF warmer (35) are connected to a downstream side of the EGR cooler (17).
