Abstract
An axial fan for conveying cooling air, in particular for an internal combustion engine of a motor vehicle. The axial fan includes a hub, on which a plurality of fan blades extending radially outward is arranged, which each have a rear blade edge. In the case of an axial fan having an optimal relationship between efficiency and flow output, a contour of the rear blade edge of the fan blades extends curved in a circumferential direction with respect to a plane spanned by an axis of rotation of the axial fan and a longitudinal extent of the fan blade.
