ABSTRACT:
An air conveying device is provided on a radiator for water cooled internal combustion engines. The device comprises a fan rotor supported on the internal combustion engine by means of a fan rotor shaft on which is located a belt pulley for a driving belt. A fan shroud surrounds the outer ends of the fan blades and is fastened to the blade tips. So that even belts with a relatively short belt length can be installed from the fan rotor direction, the fan shroud has at least one slot extending in the axial direction for inserting the belt and for slipping the length of belt which is positioned at the shaft-free end of the fan rotor over the fan shroud.
