Ventilation arrangement

摘要

A ventilation arrangement for a wind turbine includes an air inlet opening (614; 678) located in a nose cone (610) of said wind turbine (100), a manhole cover (650) for covering a manhole (624) of a rotor hub (620) of said wind turbine (100), the manhole cover (650) providing a vent opening (654; 656; 636) for venting hot air (H) from an internal space (622) of said rotor hub (620), and a flexible piping (680) establishing fluid communication between the internal space (622) of the rotor hub and the air inlet opening (614).
