CA 2446632

The present invention concerns a wind power installation comprising a ring generator and a housing having a heat-conducting housing portion in the region of the ring generator. Previously known structures suffer from the disadvantage that mechanical vibrations and oscillations of the generator can be perceived as acoustic disturbance and interference. The object of the present invention is very substantially to eliminate that disadvantage. A wind power installation comprising a ring generator and a pod housing, which surrounds the ring generator, of the wind power installation, wherein the pod housing has a heat-conducting housing portion in the region of the ring generator and a predetermined spacing is provided between the outside periphery of the ring generator and the heat--dissipating housing portion.

La présente invention concerne un dispositif d'énergie éolienne comprenant un générateur annulaire (16, 18) et un logement (14) comportant une partie de logement de dissipation de chaleur (20) dans la zone du générateur annulaire. Les dispositifs selon l'art antérieur présentent l'inconvénient que les vibrations mécaniques du générateur peuvent être perçues comme des nuisances acoustiques. L'objectif de l'invention est d'éliminer cet inconvénient du mieux possible. A cet effet, un espace défini est ménagé entre le pourtour extérieur du générateur annulaire et la partie de dissipation de chaleur du logement.
