Abstract:
A cooling system for a motor vehicle, has a first cooling circuit arrangement with a first coolant cooler and a second coolant circuit arrangement with a second coolant cooler. A cooling air supply to the first coolant cooler can be varied by means of a first cover device, and a cooling air supply to the second coolant cooler can be varied by means of a second cover device. The first cover device and the second cover device can be moved by means of an interposed gear of a shared drive, whereby the gear is configured such that, when the drive is being operated for opening purposes, the second cover device is moved earlier and/or faster than the first cover device out of a closed position in the direction of an open position. This makes it possible to supply cooling air to meet an already existent cooling demand of the second coolant cooler, whereas such a cooling demand does not yet exist for the first coolant cooler, so that the latter can still remain covered—in terms of a flow of cooling air—by means of the associated (first) cover device. This can have a positive effect on the flow resistance for the cooling air and thus on the aerodynamics of the motor vehicle.
