摘要
An impeller wheel for fans has a bottom disc, a cover disc, and three-dimensionally shaped blades connected to the bottom disc and the cover disc. The bottom disc, cover disc, and the blades form a one-piece part. The blades have a leading edge and a trailing edge, wherein the leading edge and the trailing edge each have a median diameter. In a projection onto a cylinder that is coaxial with a rotation axis of the impeller wheel and has a diameter matching a median diameter of the trailing edge or of the leading edge, a first extension of the trailing edge and/or the leading edge is positioned at a first angle and a second extension of the trailing edge and/or the leading edge is positioned at a second angle relative to a line parallel to the rotation axis. At least one of the first and second angles is different from 0°.
