COOLING SYSTEM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To discharge large quantity of heat. SOLUTION: The present invention provides a temperature elevating device 4 for an electric vehicle or a hybrid vehicle, in particular, a vehicular cooling system 1 for a battery for traveling or a fuel cell. A coolant 7 for cooling the device 4 is used utilizing an air-conditioner 8 serving for air-conditioning for a cabin of the vehicle. The coolant 7 is a cooling liquid passing through a cooling circuit 2 and coupled thermally to a refrigerating cycle 3 of the air- conditioner for cooling the liquid. The coolant 7 is connected to a refrigerant 15 of the air-conditioner 8 via the first heat exchanger 6. The cooling liquid 7 maintains a flocculation condition all the time. The present invention relates also to a method for cooling the vehicular temperature elevating device.
