Coil cooling structure

Abstract

A coil cooling structure comprises a coil which includes a strip-shaped conductor wound around a specific axis a plurality of times; an alumina layer which is formed on an end surface of the coil in the direction of the specific axis through thermal spraying of alumina and whose surface is flattened; a cooling plate which is mainly formed of alumina and has a flow passage for a cooling medium; and an adhesive which bonds the alumina layer and the cooling plate and which elastically deforms depending on a difference in thermal expansion between the alumina layer and the cooling plate.
