Patent ID: 8053918

Claim:
A wind power installation comprising: a pylon; a pod mounted rotatably on the pylon, the pod having a front interior portion and a rear interior portion; a generator arranged within the pod between the front interior portion and the rear interior portion, the generator including a rotor and a stator and having an air gap between the rotor and the stator; at least one fan in the region of the pod, the fan being arranged to draw outside air into the rear interior portion of the pod through a downwardly open first air gap positioned between the pylon and the pod and force the outside air through the air gap between the rotor and the stator into a front interior portion of the pod; a pod fairing surrounding at least a portion of the rear interior portion of the pod, the pod fairing configured to guide the outside air toward the air gap between the rotor and the stator; and seal structures positioned in the pod to substantially prevent air flow from bypassing the air gap between the rotor and the stator when the outside air is forced from the rear interior portion to the front interior portion.
