Abstract

See full text

A wind power generator set, an electromagnetic device and a heat exchange or drying device for an iron core. The heat exchange or drying device for an iron core includes a sprayer capable of feeding an airflow, wherein the sprayer is provided with a spraying hole, and the airflow can be sprayed to an end of the iron core through the spraying hole. The sprayer sprays a cold airflow or a hot airflow at the end of the iron core, creating a cooling and drying environment at the end of the iron core. This facilitates the heat dissipation of the iron core and also the maintenance of the insulation performance of an end of a winding, including the insulation of the winding itself and the insulation between the winding and the iron core, and also the protection of a magnetic pole and a protective covering layer thereof.
