Nozzle for guiding an air flow towards a heat exchanger of a motor vehicle and corresponding vehicle

摘要

The nozzle has shutters (28) articulated between closed and open positions to close and unblock auxiliary air openings (20). The shutters are articulated for being moved into the closed position due to the pressure difference on both sides of the shutters during the operation of a motorized axial flow impeller. The shutters are articulated around an axis vertically so as to be returned to the closed position due to their own weight. An independent claim is also included for a motor vehicle comprising a heat exchanger and a nozzle.
