Abstract
The present disclosure relates to a radial fan wheel having a plurality of fan wheel blades arranged in a blade ring and at least one plate that, at least in sections, covers the fan wheel blades axially on the front side, wherein two adjacent fan wheel blades form a blade channel therebetween, the flow cross section of which is axially limited by the plate; an axial width of the blade channel increases to a maximum (M) at least along an outer periphery of the radial fan wheel starting from a suction side (S) of a fan wheel blade limiting the blade channel in the direction of a pressure side (D) of the adjacent fan wheel blade limiting the blade channel; wherein the maximum lies on a radial section of the fan wheel, which radial section lies between 55 and 95% of the distance between the suction side (S) of the fan wheel blade limiting the blade channel and the pressure side (D) of the adjacent fan wheel blade limiting the blade channel such that the plate, when viewed in the circumferential direction, has an asymmetrical shape between two adjacent fan wheel blades.
