WIND TURBINE WITH VENTILATION ARRANGEMENT

摘要

Some embodiments of the invention relates to a wind turbine generator comprising a hub with an interior hub space, a nose cone with a nose cone wall, and a ventilation system for ventilating the hub of the wind turbine generator, wherein a deepening in the nose cone wall is provided, wherein the ventilation system comprises air flow means for directing air from outside of the hub towards the interior hub space, said air flow means comprising an entrance section, wherein the ventilation system further comprises air diverting means, wherein the air flow means are disposed at a distance to the air diverting means or wherein the air flow means are disposed conterminous to the air diverting means but not in the interior space of the air diverting means, and wherein the deepening, the entrance section of the air flow means and the air diverting means together define an air channel system for directing air from the outside of the wind turbine generator into the air flow means. Further, some embodiments of the invention relates to a wind turbine generator comprising a hub, a nose cone with a nose cone wall and an interior nose cone space, and a ventilation system for ventilating the hub of the wind turbine generator, wherein an opening in the nose cone wall is provided, wherein the ventilation system further comprises air diverting means and wherein the air diverting means are at least partly disposed in the interior nose cone space.
