Claims

[Scope of utility model registration request]

A large number of disc-shaped unit windings are stacked with spacers interposed therebetween so that horizontal flow paths for cooling medium are formed between them, and an inner insulating cylinder is provided on the inner peripheral side of the windings.
Outer insulating tubes are arranged on the outer circumferential side so that the inner circumferential vertical flow path and the outer circumferential vertical flow path for the cooling medium are formed therebetween, and the inner circumferential insulating tubes are arranged for each of the plurality of unit windings. Circumferential vertical flow channels Disposed flow plates that alternately close the outer peripheral vertical flow channels so that the cooling medium flows in a zigzag pattern for each of the plurality of unit windings,
forming recesses in the outer circumferential edge of the folding plate that closes the outer circumferential vertical flow path so as to correspond to both sides of an opening that the inner insulating cylinder has for allowing the connecting wire between sections of the unit winding to escape; An elastic tube elongated in the stacking direction of the unit winding is accommodated in the recess and brought into pressure contact with the inner surface of both sides of the opening of the outer insulating cylinder, the outer peripheral surface of the unit winding, and the side surface of the spacer. A cooling device for a disk winding, characterized in that a large number of slits are formed in the elastic tube, and the slit forming surface is brought into contact with the outer peripheral surface of each of the unit windings.
