Abstract

Die Erfindung betrifft ein Kühlsystem für ein Kraftfahrzeug, mit einem Kühler (1), der von Kühlmittel durchflossen wird, das insbesondere zur Kühlung einer Brennkraftmaschine (2) dient, und der von einer Kühlluftströmung durchströmt wird, die, in Abhängigkeit von der Geschwindigkeit des Kraftfahrzeugs, von einem Lüfter (8), insbesondere einem Axiallüfter, beeinflusst wird, der zwischen dem Kühler (1) und der Brennkraftmaschine (2) angeordnet ist und eine drehbar angetriebene Nabe (9) aufweist, an der Lüfterblätter (12) befestigt sind, die in einem Luftdurchtrittsraum angeordnet sind, der radial außen von einem Zargenring (15) mit einem Zargenringdurchmesser (Dz) begrenzt wird, wobei die in Luftdurchströmungsrichtung hinteren Kanten (13) der Lüfterblätter (12) in einem Abstand (A) zu einer Stirnwand (4) der Brennkraftmaschine angeordnet sind.The invention relates to a cooling system for a motor vehicle, comprising a radiator (1) through which coolant flows, which serves in particular for cooling an internal combustion engine (2), and which is traversed by a flow of cooling air which, depending on the speed of the motor vehicle , is influenced by a fan (8), in particular an axial fan, which is arranged between the radiator (1) and the internal combustion engine (2) and has a rotatably driven hub (9) to which fan blades (12) are attached are arranged in an air passage space, which is bounded radially on the outside by a frame ring (15) with a Zargenringdurchmesser (Dz), wherein the air flow in the rear direction edges (13) of the fan blades (12) at a distance (A) to an end wall (4) the internal combustion engine are arranged.

Um ein Kühlsystem zu schaffen, das eine hohe Kühlleistung liefert und eine stabile Lüfterkennlinie aufweist, weisen die in Strömungsrichtung hinteren Kanten (13) der Lüfterblätter (12) zu der Stirnwand (4) der Brennkraftmaschine (2) hin gegenüber dem Zargenring (15) einen Überstand (U) auf.
