Abstract
A circumferentially banded fan that forces air through an adjacent heat exchanger and that has an air-guide housing positioned radially outside the band and extending downstream therefrom is disclosed. A plurality of elongated stationary members extend radially inwardly from the housing downstream from the fan blades, and the stationary members have a flow-control surface which removes the rotational component imparted to the airflow by the rotating fan blades. A tangent to the flow control surfaces at their radial center line forms an angle with the airflow exiting the blades which is substantially equal to the tangent-to-axis angle.
