A 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 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 fan wheel of the type described above, and a motor vehicle with such a radiator fan module.

Fan wheel and radiator fan module with the fan wheel

A fan wheel has a hub cup and a plurality of blades which are arranged on the hub cup and extend 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, an axial unit depth z*(t) of the blade has an aperiodically wave-like shape. A radiator fan module has a fan wheel of the type described above, and the fan wheel can be used in a motor vehicle.
