| 摘要 |
The invention relates to a wind turbine comprising a solar updraft chimney (1) and a ring of flow channels (4) surrounding the solar updraft chimney (1), said flow channels extending between support walls (3) that extend radially relative to the solar updraft chimney (1) and that receive a bearing ring (2) for the solar updraft chimney (1). In order to achieve an advantageous action of the wind on the solar updraft chimney (1), the ring of flow channels (4) is surrounded by a wind guiding device (9) which is symmetrical to an axial plane (16) of the solar updraft chimney (1). Said wind guiding device comprises an open peripheral side (17) extending across an angle sector of 180° and a closed peripheral side (18) opposite the open peripheral side (17), the wind guiding device (9), on the closed peripheral side (18), forming two peripheral walls (22) in the radial direction which are contiguous to the ring of flow channels (4) in the area of the plane of symmetry, said peripheral walls gradually extending away from the ring of flow channels (4) towards the open peripheral side (17). The wind guiding device (9) is rotatably mounted about the axis of the solar updraft chimney (1). |
