Abstract
Abstract The invention relates to a cooling system for a motor vehicle comprising a first heat exchanger ( 1 ), in particular, embodied in the form of a main cooler for cooling a first liquid coolant ( 3 ) of an internal combustion engine ( 2 ) by means of an air flow coming from the ambient air and a second heat exchanger ( 7, 13, 407, 415 ) for cooling gases introduceable into the internal combustion engine, in particular, exhaust gases and/or charge air, wherein the second heat exchanger ( 7, 13, 407, 415 ) is coolable by the an air flow coming from the ambient air and is spatially separated from the main cooler ( 1 ).

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
157 words
A cooling system for a motor vehicle, comprising: a main cooler arranged substantially in a front of the motor vehicle and configured to cool a liquid coolant to be supplied to an internal combustion engine, wherein the liquid coolant is cooled by a first flow of ambient air; a second cooler configured to cool a flow of gas to be supplied to the internal combustion engine, wherein the flow of gas is cooled by a second flow of ambient air; a main fan configured to provide at least a portion of the first flow of ambient air; and an air feeder configured to provide at least a portion of the second flow of ambient air, wherein the second cooler is separate from the main cooler, wherein the air feeder is separate from the main fan, wherein the first flow of ambient air and the second flow of ambient air are extracted from the environment at different locations.
