COOLING SYSTEM FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To downsize and simplify a cooling system for a hybrid vehicle, while securing enough and sufficient cooling capacity.

SOLUTION: The cooling capacity of a third radiator 8 is changed between the capacity for cooling an engine 1 and the capacity for cooling an electric motor 2, a motor drive device 3 and the engine 1. Since the third radiator 8 can be commonly used for cooling the engine 1 and for cooling the electric motor 2 and motor drive device 3, the cooling system for a hybrid vehicle is downsized and simplified while securing the enough and sufficient cooling capacity.
