<P>PROBLEM TO BE SOLVED: To provide a winding wire cooling structure for obtaining a cooling effect without using inner and outer clogging boards with complicated shapes, which ensures the same effect as in using the boards. <P>SOLUTION: A plurality of disk shape winding wires 3, where wire conductors are wound, are coaxially arranged by superimposition between the inner and outer insulating cylinders 1, 2 in a vertical direction, in order to efficiently pass a refrigerant. A plurality of horizontal interval pieces 4 are radially arranged and equally spaced between the vertically adjacent disk shape winding wires 3, so as to radially form a plurality of fan-shaped horizontal cooling passages 5. A plurality of vertical interval pieces 6, 7 are arranged between the inner and outer insulating cylinders 1, 2 and the disk shape winding wires 3, so as to meet the inner and outer circumferences of the horizontal interval pieces. Then, a plurality of inner vertical cooling passages 8 and outer vertical cooling passages 9 are formed in the circumferential direction. Consequently, a plurality of cooling sections of the inner and outer vertical cooling passages 8, 9, which communicate with the plurality of horizontal cooling passages, are formed in the circumferential direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
