COOLING SYSTEM FOR A VEHICLE, IN PARTICULAR A COMMERCIAL VEHICLE

The invention relates to a cooling system for a vehicle, in particular for a utility vehicle, with a high-temperature cooling circuit (HT cooling circuit, 3), by means of which an internal combustion engine (5), in particular a cylinder-piston unit, of the vehicle can be cooled, wherein at least one charge-air cooler (7) is provided, by means of which the combustion air (23) that can be supplied to the internal combustion engine (5) can be cooled, wherein an energy recovery device (ER device, 11) is provided, by means of which energy can be obtained from and/or generated from waste heat of the internal combustion engine (5), in particular mechanical and/or electrical energy, wherein the ER device (11) has a heat-supplying heat exchanger (43), by means of which the waste heat of the internal combustion engine (5) can be supplied to the ER device (11), and wherein the ER device (11) has a heat-dissipating heat exchanger (9). According to the invention, a low-temperature cooling circuit (NT cooling circuit, 6) that has a lower temperature than the HT cooling circuit (3) is provided, by means of which both the at least one charge-air cooler (7) and the heat-dissipating heat exchanger (9) of the ER device (11) can be cooled.
