GUIDE GEOMETRY FOR HALF-AXIAL FAN WHEELS

摘要

A fan wheel (150) of a fan (130) comprises suction blades (210) having a leading edge (220) facing an axial inlet direction of the fan wheel, and exhaust blades (230) having an exhaust edge (240) facing a radial outlet direction of the fan wheel, as well as one deflecting element (270) connected positively or non-positively to at least one exhaust blade so as to deflect air from an active area of the suction blades (210) to an active area of the exhaust blades.
