Abstract
A ventilation arrangement for a wind turbine includes a manhole cover for covering a manhole of a rotor hub. The rotor hub is contained within the nose cone and spaced therefrom to form an internal space between an inner surface of the nose cone and an outer surface of the rotor hub. The manhole cover provides a vent opening for venting hot air from an interior space of the rotor hub into the internal space. A pipe extends from a forward internal space through the manhole cover and into the rotor hub. The pipe establishes fluid communication between the forward internal space and the interior space. A fan is mounted to the pipe, and draws air from the forward internal space. An exhaust, fluidly connected with the pipe, is located in the rotor hub and away from the manhole cover by 50% to 90% of a rotor hub axial length.
