Abstract

The invention relates to a vehicle cooling system (1) for a temperature-raising device (4), especially a drive battery or fuel cell, preferably for an electric or hybrid vehicle. The system has a coolant (7) that cools the device (4) with the involvement of an air-conditioning system (8) that serves for air-conditioning of the vehicle passenger compartment. It is preferred that the coolant (7) be a liquid coolant, which is carried in a cooling circuit (2) and for cooling of the liquid to be thermally integrated into the refrigeration circuit (3) of the air-conditioning system. The invention further relates to a method for cooling a temperature-raising vehicle device.
