Claims

[Scope of utility model registration request]

A horizontal flow path is formed between each unit winding of a spiral winding made by lining up a large number of conductors flatly and winding them in a spiral, and an inner insulating cylinder is placed around the inner circumference of the winding, and an inner insulating cylinder is placed around the outer circumference of the winding. Inner and outer vertical flow paths are formed between each winding of the outer insulating cylinder, and each of the plurality of unit windings is interposed by being separated at one point in the circumferential direction. Annular inner and outer folding plates are provided to alternately block the passages, and the cooling fluid is caused to flow in a zigzag pattern for each of the plurality of unit windings, the outer folding plates The outer vertical channel has a width equivalent to the width of the outer vertical channel, extends to the other side, and is bent into a U-shape on at least one side of the separated and vertically spaced portion. 1. A cooling device for a spiral winding, characterized in that a closing piece is provided therein to close the gap between the separated portions of the outer folding plates.
