AI Technical Summary
【0008】 本発明によれば、整流部によって自然対流する絶縁液体を放熱フィンに向かって流れるよう案内でき、放熱フィンを流れる絶縁液体の量を増加することができる。これにより、放熱フィンから放出する熱量を増大して冷却効率を向上することができる。特に、粘度が高い植物油を絶縁液体に用いた場合でも、冷却効率を向上できるようになり、環境問題の解消に寄与することもできる。

Abstract
Claims
1. A container for housing windings, an iron core, and insulating liquid, A heat dissipation fin is formed that protrudes outward from the side wall of the container and extends vertically, It includes a rectifier positioned above the winding, A static induction electric device that cools the windings while releasing heat from the heat dissipation fins via the naturally circulating insulating liquid, The iron core comprises a plurality of legs extending in the vertical direction and an opening that penetrates in a predetermined direction. The rectifying section comprises an inclined surface portion that slopes upward as it approaches the inner surface of the side wall, and a support surface portion that extends downward from the lower end of the inclined surface portion, and guides the insulating liquid circulating inside the container toward the heat dissipation fins. A static induction electric device characterized in that the support surface portion is not formed at a position directly above the opening.
2. The static induction electric device according to claim 1, characterized in that the upper end of the inclined surface portion is provided at a position substantially the same as or lower than the upper end position of the heat dissipation fin.
3. The static induction electric device according to claim 1 or 2, characterized in that the inclined surface portion is formed in an endless loop shape when viewed from above.
