Abstract
An axial fan arrangement is provided, especially for the radiator of a water cooled internal combustion engine for commercial vehicles. In order to reduce noise levels without impairing fan efficiency, an air guide structure is provided which widens in the flow direction starting from adjacent the air inlet edges of the fan blades. Embodiments are included which have part of the air guide structure carried by the fan blades and other embodiments have fixed air guide structure. The contour of the air guide structure conforms to the facing contour of the fan blades.
