Cooling system

The cooling system for an internal combustion engine has a first circuit for a first fluid with a first heat exchanger (1) for an exchange of heat between the first and a second fluid. A second circuit for a third fluid (4) has a second heat exchanger for an exchange of heat between the third and a fourth fluid (6). A first fluid feed unit is provided to feed the second fluid through the first heat exchanger, and a second fluid feed unit is provided to feed the fourth fluid through the second heat exchanger. The first fluid and/or the third fluid are liquid, and the second and third are gaseous and especially air.
