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

Vehicle cooling system for a temperature-raising device and method for the cooling of a temperature-raising device

The device is used to cool a vehicle appliance, in particular a battery or a fuel cell, by means of a coolant. It has a plurality of identically designed cooling elements, through which coolant can flow, which can be brought into bearing contact to cool at least one component of the vehicle appliance. It includes a first cooling-element side and a second cooling-element side which is on the opposite side from the first cooling-element side. The cooling-element sides have connection openings, which form inlet and outlet openings for the coolant and are in communication with the interior space of the cooling element. In this arrangement, it is provided for the first and second cooling-element sides each to have at least two connection openings.
