Cooling System

The invention relates to a cooling system ( 1 ) for a motor vehicle ( 3 ), comprising at least one heat exchanger ( 14, 15 ), in particular an intercooler, which is traversed by a medium, in particular a coolant that is used to cool a motor ( 9 ) and which comprises a heat exchanger air-penetration surface that is traversed by an air stream along a first stream path ( 26 ) in a first operating mode, in particular a back-pressure mode and is additionally or alternatively traversed by an air stream along a second stream path ( 24 ) running through an air conduction unit ( 20 ) in a second operating mode, in particular a ventilator mode. The air conduction unit is located between the heat exchanger ( 14, 15 ) and the motor ( 9 ) and comprises a conduction air-penetration surface. The aim of the invention is to provide a cooling system, in which the cooling air stream is obstructed as little as possible along the first stream path ( 26 ) in the first operating mode and which permits the cooling air stream to be conducted along the second stream path ( 24 ) with minimal loss. To achieve this, the air-conduction device ( 20 ) and the heat exchanger ( 14, 15 ) are configured and arranged in such a way that a parallel projection of the conduction air-penetration surface in the longitudinal direction ( 8 ) of the vehicle ( 3 ) on the plane containing the heat-exchanger air-penetration surface, protrudes at least partly beyond said heat-exchanger air-penetration surface and that a significant part of the heat-exchanger air-penetration surface is not covered by the parallel projection of the conduction air-penetration surface.
