Abstract

Die Erfindung betrifft einen Lüfter (1) eines Kühlgebläses für mindestens einen stauluftbeaufschlagbaren Wärmeübertrager eines Kraftfahrzeuges, wobei der Lüfter (1) in Luftströmungsrichtung hinter dem Wärmeübertrager angeordnet ist, in einer Zarge einer Lüfterhaube umläuft und eine Lüfternabe (2) mit einer Nabenstimfläche (4) sowie umfangsseitig angeordneten Lüfterschaufeln (3) aufweist.The invention relates to a fan (1) of a cooling fan for at least one Stauluftbeaufschlagbaren heat exchanger of a motor vehicle, wherein the fan (1) arranged in the air flow direction behind the heat exchanger is, in a frame of a fan cover rotates and a fan hub (2) with a hub end face (4) and circumferentially arranged fan blades (3).

Es wird vorgeschlagen, dass die Lüfternabe (2) Luftdurchtrittsöffnungen (5) aufweist, die durch bewegliche Verschlusselemente (7) in ihrem Öffnungsquerschnitt veränderbar sind.
