Cooling device in a vehicle

Cooling device for an internal combustion engine, especially in a vehicle, with a running as a thermoelectric generator voltage generating part (5), whose one side faces a cooling flow through the cooling device (1), wherein the cooling flow of the cooling device (1) dissipate heat of a unit in the vehicle, wherein the cooling device is designed as a vehicle radiator (1) and the voltage generating part (5) in the vehicle radiator (1) integrated, wherein the voltage generating part (5) and a cooling fin (2) of the vehicle radiator (1) form a common structural unit, characterized in that that the voltage-generating member (5) is formed as a separate component which rests against the outer wall of the cooling fin (2), wherein the voltage generating part (5) in such a way on the outer wall of the cooling fin (2) is applied such that a laminate is formed.
