A vehicle cooling system, - comprising at least one cooling means of a cooling circuit for cooling at least one main component of the vehicle, wherein the cooling means can have cooling air flowing through it, - comprising at least two fan chambers (7, 8) which each adjoin an outlet side of the at least one cooling means, in each of which one fan (10, 11) is arranged and which each have a main outlet (12, 13) for cooling air and an ancillary outlet (14, 15) for cooling air, - comprising at least one waste air channel for supplying cooling air to at least one ancillary component of the vehicle to be cooled, which is connected to ancillary outlets (14, 15), - comprising at least one control device for controlling a cross-section of the ancillary outlets (14, 15) through which cooling air can flow, - wherein the fan chambers comprises a first fan chamber with a first fan, a first main outlet and a first ancillary outlet as well as a second fan chamber with a second fan, a second main outlet and a second ancillary outlet, - wherein the second main outlet has a larger cross-section through which cooling air can flow than the first main outlet, - wherein the control device is configured and/or programmed so that it enables operation of the vehicle cooling system in a normal operating state and in at least two emergency operating states comprising a first emergency operating state and a second emergency operating state, - wherein the control device in the normal operating state in which the first fan and the second fan are switched on, opens the first ancillary outlet and closes the second ancillary outlet so that cooling air driven by the first fan flows from the first fan chamber through the first ancillary outlet and through the waste air channel whilst cooling air driven by the second fan flows from the second fan chamber bypassing the waste air channel through the second main outlet, - wherein the control device in the first emergency operating state in which the first fan is switched off and the second fan is switched on closes the first ancillary outlet and opens the second ancillary outlet so that cooling air driven by the second fan flows from the second fan chamber through the second ancillary outlet and through the waste air channel, - wherein the control device in the second emergency operating state in which the first fan is switched on and the second fan is switched off, opens the first ancillary outlet and closes the second ancillary outlet so that cooling air driven by the first fan flows from the first fan chamber through the first ancillary outlet and through the waste air channel. - comprising at least one cooling means of a cooling circuit for cooling at least one main component of the vehicle, wherein the cooling means can have cooling air flowing through it, - comprising at least two fan chambers (7, 8) which each adjoin an outlet side of the at least one cooling means, in each of which one fan (10, 11) is arranged and which each have a main outlet (12, 13) for cooling air and an ancillary outlet (14, 15) for cooling air, - comprising at least one waste air channel for supplying cooling air to at least one ancillary component of the vehicle to be cooled, which is connected to ancillary outlets (14, 15), - comprising at least one control device for controlling a cross-section of the ancillary outlets (14, 15) through which cooling air can flow, - wherein the fan chambers comprises a first fan chamber with a first fan, a first main outlet and a first ancillary outlet as well as a second fan chamber with a second fan, a second main outlet and a second ancillary outlet, - wherein the second main outlet has a larger cross-section through which cooling air can flow than the first main outlet, - wherein the control device is configured and/or programmed so that it enables operation of the vehicle cooling system in a normal operating state and in at least two emergency operating states comprising a first emergency operating state and a second emergency operating state, - wherein the control device in the normal operating state in which the first fan and the second fan are switched on, opens the first ancillary outlet and closes the second ancillary outlet so that cooling air driven by the first fan flows from the first fan chamber through the first ancillary outlet and through the waste air channel whilst cooling air driven by the second fan flows from the second fan chamber bypassing the waste air channel through the second main outlet, - wherein the control device in the first emergency operating state in which the first fan is switched off and the second fan is switched on closes the first ancillary outlet and opens the second ancillary outlet so that cooling air driven by the second fan flows from the second fan chamber through the second ancillary outlet and through the waste air channel, - wherein the control device in the second emergency operating state in which the first fan is switched on and the second fan is switched off, opens the first ancillary outlet and closes the second ancillary outlet so that cooling air driven by the first fan flows from the first fan chamber through the first ancillary outlet and through the waste air channel.
