| 摘要 |
The invention relates to a device for converting wind energy to at least mechanical energy, comprising a rotor with a number of rotor blades drivable rotatably about a rotation axis by wind and a duct disposed round the rotor, wherein a central axis of the duct substantially coincides with the rotation axis of the rotor. The converting device is further provided with guide means disposed downstream of the rotor for guiding the wind away in a substantially downstream direction. The guide means as seen in flow direction are disposed directly behind the rotor blades and/or have a form adapted to the rotor blades. |
