<P>PROBLEM TO BE SOLVED: To sufficiently secure both cooling performance of an engine 1 and cooling performance of at least one of a motor 2 and an inverter 3 with a relatively simple constitution, in a cooling device of a hybrid vehicle of using the engine 1 and the motor 2. <P>SOLUTION: This cooling device includes an upstream side heat exchange part 7A interposed on the downstream side of a water pump 6 in a circulating passage 4 for taking out and returning a cooling liquid of the engine 1, a downstream side heat exchange part 7B integrally arranged adjacent to the upstream side heat exchange part 7A and introducing a part of the cooling liquid of reaching the downstream side of the upstream side heat exchange part 7A, and a cooling flow passage 9 for returning the cooling liquid discharged from the downstream side heat exchange part 7B to the upstream side of the water pump 6 in the circulating passage 4 after flowing it so that heat can be exchanged with at least any one of the motor 2 and the inverter 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
