Abstract
The invention relates to an axial fan, in particular for radiators of motor vehicles, the axial blades being fastened to a fan hub, and the fan hub in turn being connected to a viscous fluid friction clutch. According to the invention, air-guide elements or guide blades are arranged in the hub region on the front side or suction side of the axial fan. These air-guide elements or guide blades deflect the flow from the front side to the rear side of the blades and thereby stabilize the flow. To further improve the flow conditions, the hub region is covered by a cap on its front side. The cooling-air flow on the front side of the viscous fluid friction clutch and the hub flow of the fan are stabilized by the air-guide elements in combination with the
