この発明の目的は誘導子の長手方向の冷却を均一にしよ
うとするものである。In the conventional example described above, the coil end of the inductor and the iron core are cooled by a cooling blower in the longitudinal direction of the iron core. With this structure, good heat exchange can be expected on the upstream side where the cooling air is directly exposed (cooling can be expected), but no cooling effect can be expected on the downstream side because there is no cooling due to the hot air that was heat exchanged on the upstream side. Therefore, the coils and iron cores on the downstream side of the cooling air have locally high temperatures, which limits the performance of the inductor. The object of this invention is to uniformly cool the inductor in the longitudinal direction.

流側ほど細い方が経済的である。The air duct installed along the coil end on the back side of the inductor has cooling air outlets at appropriate pitches, and the cooling air from these outlets cools the inductor uniformly. [Example] Figures 1 and 2 show examples. In the drawing, the cooling air from the cooling blower 3 passes through a pair of ducts 4 along the coil end 2 and is blown out almost uniformly from the outlet 5 to cool the inductor iron core 1 and the coil end 2. It is more economical for the duct 4 to be thinner toward the downstream side.
なお両コイルエンド２に対し、１個の冷却ブロアを使用
し、分流させてもよい。Note that one cooling blower may be used for both coil ends 2 and the flow may be divided.
