COOLING SYSTEM

摘要

The invention describes an airflow control arrangement (100) for a direct-drive wind-turbine (10) with a generator (14) comprising a rotor (11) and a stator (12), which airflow control arrangement (100) comprises an outflow fan (1) arranged to draw an exit airflow (AF_out) through an exit duct (4), which exit duct (4) extends from an interior cavity (120) of the stator (12) to the exterior of the wind turbine (10). The invention further describes a direct-drive wind turbine (10) comprising such an airflow control arrangement (100). The invention further describes a method of controlling an airflow (AF_in, AF_out) in a direct-drive wind-turbine (10) with a generator (14) comprising a rotor (11) and a stator (12).
