PROBLEM TO BE SOLVED: To solve a problem of a conventional tank for induction apparatus including a radiator that compaction is difficult because the shape of the radiator is increased or the number thereof is increased for enhancing the heat radiation effect.SOLUTION: A cylindrical tank 1 is constituted of a dome-like upper lid 11, a disc-shaped bottom plate 12 and a cylindrical trunk 13, and in which insulating oil for cooling and insulation and the induction apparatus body are housed. A radiator 15 consisting of a plurality of heat radiation fins 151 is provided in the central part of the side face of the trunk 13. The trunk 13 where the plurality of heat radiation fins 151 are protruding is formed integrally by press molding an aluminum material. The radiator 15 can be made compact by using an aluminum material having thermal conductivity higher than that of a soft iron material in the trunk 13.SELECTED DRAWING: Figure 1 |
