Cooling System
First Claim
1. A cooling system for a motor vehicle, having at least one heat exchanger, in particular a cooler, which cooler is traversed by a medium, in particular coolant, which serves for example to cool an engine, and which cooler has a heat exchanger air-passage surface which, in a first operating phase, in particular in a so-called ram-pressure mode, is traversed by an air flow along a first air flow path and which, in a second operating phase, in particular in a so-called fan mode, is additionally or alternatively traversed by an air flow along a second air flow path which runs through an air feed device which is arranged between the heat exchanger and the engine and has a feed air-passage surface, wherein the air feed device and the heat exchanger are designed and arranged in such a way that a parallel projection of the feed air-passage surface in the longitudinal direction of the vehicle onto the plane in which the heat exchanger air-passage surface is situated protrudes at least partially beyond the heat exchanger air-passage surface, and in that a significant part of the heat exchanger air-passage surface is not overlapped by the parallel projection of the feed air-passage surface.

Abstract
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.
