An axial mini ventilator having an air conduction housing with an impeller wheel on the suction-side end of a tubular flow channel. Formed on the inside of the air conduction housing are air baffles which support the stator of an electric drive motor for the impeller wheel. The tip and/or root lines of the baffles are essentially segments of a parabola. The parabolas are oriented so that their point of origin is on the pressure-side end of the flow channel, and their plane of symmetry runs at right angles to the direction of flow. As a result of this configuration of the baffles, the turbulence in the flow channel can be reduced and the efficiency can be significantly increased. |
