fan wheel with strömungsöffnungen for performance

摘要

Fan wheel, characterized in that the hollow profile blade (5,5 ') of the fan wheel (1) at the blade trailing edge (9,9') the recess (4,4 '), the flow channel (7,7') and the flow bore (8,8 ', n) each comprises all of which are in fluid communication with one another, so that in the case of rotation of the hollow profile blade (5,5') in the direction of rotation (2) as a consequence of the centrifugal force via the bore (8,8 ') inflowing gas molecules through the flow channel (7,7') and flow via the recess (4,4 ') to emerge again therefrom, wherein a fan motor force - or in a form-fitting manner to the motor shaft (10) is connected.
