Abstract
The cooling air circulation system at the front end of a motor vehicle has several separate air ducts which are arranged one on top of the other and in which a water cooler and a supplementary cooler are position. Improved cooling is achieved by the cooling air of an upper and central air duct being conveyed to the water cooler, in front of which are mounted in the upper air duct only a condenser of an air-conditioning system and an electric fan, and by a lower air duct, in which the supplementary cooler is arranged, leading into an opening in front of the water cooler on the underside of the front end.
