Abstract (en)
[origin: CN109424581A] The present invention relates to a fan wheel and cooling fan module comprising such fan wheel. The fan wheel has a hub cup and a plurality of blades extending radially outward from an outer wall of the hub cup, which is in particular at least substantially cylindrical. Each blade has a leading edge and a trailing edge, wherein for at least one blade, the progression of a relative position POS_HK(t) of the blade's leading edge and/or the progression of a relative position of the blade's trailing edge has an aperiodically wave-like shape. There is also described a radiator fan module with a fanwheel of the type described above, and a motor vehicle with such a radiator fan module.
