Air stream control unit for motor vehicle, has air guidance units placed between radially arranged bars whose sides include inclined air guidance surfaces, in which air is passed between bars by plates for producing swirling air stream

摘要

The control unit has plates, which are permeable to air and include radially arranged bars. Air guidance units are arranged between two bars. The plates are serially arranged in an axial direction and are pivoted at an axis such that inclined air guidance surfaces are formed at the sides of the bars. Air is passed between the bars by the plates for producing a swirling air stream.
