GENERATOR COOLING ARRANGEMENT

摘要

A cooling arrangement configured to cool stator windings of the stator of a generator, the cooling arrangement including an inflow guiding means for guiding a cooling airflow into axial winding channels, wherein an axial winding channel extends along a gap between adjacent stator windings in a direction essentially parallel to an axis of rotation of the generator, and subsequently into an interior cavity of the stator, and an outflow guiding means for removing the cooling airflow from the interior cavity of the stator is provided. A generator including an outer rotor and an inner stator, the stator including an arrangement of stator teeth about an annular supporting structure and a plurality of windings arranged pair-wise between adjacent stator teeth, and wherein the stator is configured for connection to a cooling arrangement is also provided. A wind turbine and a method is further provided.
