Abstract
An axial fan arrangement for the radiator of an internal combustion engine including an annular bypass channel terminating between the fan frame and the fan. The bypass channel is open to the pressure sided of the fan and is designed such that the bypass flow emerging on the intake side of the fan is deflected in the direction of the main flow. By these measures the stabilization of a back flow vortex is rendered unnecessary.
Claims23
Axial fan arrangement for the radiator of an internal combustion engine, comprising:
- fan blades, and
- a fixed jacket surrounding the fan blades and mounted at a distance from a radiator frame mounted on a vehicle radiator,
- wherein an annular bypass channel terminates between the radiator frame and the fan, which bypass channel is open on a pressure side of the fan and whose inside wall facing a main flow guided through the frame has a curvature such that the bypass flow emerging on the intake side of the fan is deflected in the direction of the main flow.
