Abstract

The invention describes a cooling arrangement (1) of a wind turbine generator (3) having an outer rotor (22) arranged about a stator (31) mounted to a shaft (23) by means of a stator frontplate (31F) and a stator backplate (31B), which cooling arrangement (1) comprises an intake path leading a cooling airflow (C) into the generator air-gap (G) from the non-drive end (NDE) of the generator (3); a number of openings (10) in the stator frontplate (31F) to lead a heated airflow (H) from the air-gap (G) into a stator interior cavity (31_int) between the stator frontplate (31F) and stator backplate (31B); and an extraction assembly (11, 12) arranged to draw the heated airflow (H) out of the stator interior cavity (31_int). The invention further describes a direct-drive wind turbine (2) with a generator (3) and such a cooling arrangement (1) to cool the generator (3). The invention further describes a method of cooling a wind turbine generator (3).
