Zusammenfassung:	Cooling a wind turbine generator It is described an arrangement (100, 200) for cooling a generator mounted in a nacelle of a wind turbine, the arrangement comprising: a cooling air inlet (105) at an outer wall (1β7) of the nacelle (103) for introducing cooling air (109) into a space region (111) inside the nacelle; an inlet fan (113) downstream the cooling air inlet (105) configured to pressurize the introduced cooling air within the space region (111); a filter system (115) downstream the inlet fan (113) and separating the space region (111) from another space region (117) inside the nacelle (103), the other space (117) region being in communication with generator portions (119) to be cooled; a duct system (129) adapted to guide a portion (130) of cooling air (132) heated by exchange of heat from the generator portions to the cooling air into the space region (111).
