ABSTRACT:
An arrangement for influencing a cooling air flow passing through a cooling air system of an internal-combustion engine of a vehicle includes a heat exchanger and a blower arranged in an air guiding housing, a cooling air outlet opening being arranged in the air guiding housing between the blower and a wall of an internal-combustion engine capsule in the area of the bottom side of the vehicle. In order to achieve a better efficiency of the blower and in order to prevent the emission of sounds from the ventilated capsule, pivotable guide blades are arranged in flow direction in front of and/or behind the running blades of the blower which, as a function of thir position, closes the cooling air inlet opening to the capsule and opens the cooling air outlet opening arranged in the air guiding space between the heat exchanger and the blower.
