ABSTRACT:
A cooling arrangement for an internal combustion engine of a motor vehicle, especially an internal combustion engine enclosed in a sound or noise absorbing shroud. The cooling arrangement includes a cooling air duct having an air intake and an air exhaust, with a radiator being disposed in the cooling air duct, which radiator cooperates with a fan disposed downstream thereof, as viewed in a normal flow direction of the cooling air. To improve the cooling capacity and the operating ranges of dynamic air ventilation, a regulating device is disposed in the air flow at a position downstream of the radiator, with the regulating device being adapted to regulate an air throughflow through the radiator. The regulating device is disposed in a vicinity of the air exhaust of the cooling air duct and the fan is located outside of the cooling air duct and connected to the air duct by a bypass cooling air conduit. The regulating device is adapted to close the air exhaust of the air duct when the fan is switched on or operating.
