Abstract

PURPOSE:To equalize temperature increase by alternately placing the first flow bending section and the second flow bending section that is formed by dividing the first thereby cooling a coil heated to high temperature locally in the first flow bending section by the adjacent second section. CONSTITUTION:An inner guiding plate 7 and an oil flow guiding member 14C and a member 14C' apart from 14C by the predetermind number of blocks, are placed between horizontal spacers of a coil 1. Members 14C and 14C' are placed alternately with the guiding plate in between in the direction of the height of the coil 1. Accordingly, the flow bending section is constructed from bottom up B, B, A, B... in a block in the direction toward the circumference, and it is A, B, B, A... in a block adjacent to the former block. As a result, flow bending sections A and B are placed alternately at the preset length in the direction of the height of the coil, while A and B are also placed adjacently in the direction toward the circumference.
