Fan wheel of radial fan for vehicle ventilation, heating or air conditioning, in which hub disk, fan blades and air intake ring form at least two insertion modules

摘要

The fan wheel (20) has a hub disk (11) and an air intake ring (12), forming an axial air intake aperture (22). The fan blades (6) are between them. These components - the disk, the fan blades and the air intake ring of the fan wheel - form at least two insertion modules (1, 2) which can be fitted to each other axially. These modules are injection molded from plastic.
