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.
A cooling arrangement for a motor vehicle internal combustion engine accommodated in a sound-absorbing shroud, the cooling arrangement including a cooling air duct means having an air intake and air exhaust, a radiator means disposed in the air duct means, and a fan means cooperable with the radiator means and disposed at a position downstream of the radiator means, as viewed in a normal flow direction of cooling air, characterized in that means are provided for regulating an air throughflow through the radiator means, the means for regulating are disposed downstream of the radiator means, as viewed in the normal flow direction of cooling air, in an area of the air exhaust of the air duct means, the fan means is disposed exteriorly of the air duct means, means are provided for communicating the fan means with the air duct means, and in that means are provided for controlling an operation of the fan means and a position of the means for regulating such that the means for regulating closes the air exhaust when the fan means is operable.
