Abstract

Bei einer Warmluftheizung befindet sich der Ventilator für die Zirkulation der Warmluft in einer Wärmekammer (20). Um zu vermeiden, dass die Temperatur der Lager - vorzugsweise Kugellager - für eine Dauerbelastung zu hoch ist, werden die Lager (50, 51) des Ventilators (24) gekühlt. Zu diesem Zweck wird den Lagern (50, 51) Kühlluft über Leitungen (54, 60) zugeführt. Die Kühlluft wird von einem Ventilator-Laufrad angesaugt und durch die Zwischenräume zwischen den Schaufeln (29) ausgestossen. Dadurch kommt man ohne zusätzliches Gebläse od. dgl. für die Kühlluft aus.
