Abstract
A radial-blade double-inlet fan (1) which includes a casing (2) with two inlet openings (8,10) facing each other, an external electrical rotor motor (14) located in casing (2), having a stator (16) and a rotor (18), and of a radial impeller (20) which is connected to rotor (18) and which axially extends on both sides beyond motor (14) into the direction of inlet openings (8,10). To absorb the oscillations, motor (14) is flexibly supported by the casing. Stator (16) is connected to stator flange (32), and rotor (18) encloses stator (16) only along one side approximately up to stator flange (32). To support motor (14), shaft (34) pivots in a pivot bearing which is attached to casing (2) by means of a flexible oscillation-absorbing element (36), with this shaft rotating with rotor (18) and extending axially beyond motor (14), on the one hand, and stator flange (32) is connected by means of a heat-conducting metal lamination directly to a flange-extending element (40) which functions as a cooling element and which is located in the flow path of a medium to be transported, with this stator flange being attached to casing (2) in such a way that the attachment is both flexible and torsion-resistant, on the other hand.
