| 摘要 |
The invention relates to an axial fan for conveying cooling air, in particular for an internal combustion engine of a motor vehicle, comprising a hub (2), on which a plurality of fan blades (4) extending radially outward is arranged, which each have a rear blade edge (8). In the case of an axial fan having an optimal relationship between efficiency and flow output, a contour (9) of the rear blade edge (8) of the fan blades (4) extends curved in a circumferential direction with respect to a plane (E) spanned by an axis of rotation of the axial fan (1) and a longitudinal extent of the fan blade (4). |
