Summary:PROBLEM TO BE SOLVED: To provide a technique for reducing nonuniformity of magnetic flux, in a reactor where a cooler is in contact with a cooler covering the periphery of a coil, and including a heat transfer member penetrating the core and coming into contact with the cooler and the coil.SOLUTION: A reactor 200 includes a core 4 embedding a coil 6, and a cooler 3 in contact with the core 4. Furthermore, the reactor includes a pair of protrusions 3b (heat transfer members) elongated in the direction of the winding axis CL of the coil and penetrating the core 4, and having one end in contact with the cooler 3 and the other end in contact with the coil 6. The pair of protrusions 3b are provided while being distributed to the opposite sides of a plane passing the winding axis CL of the coil 6 and perpendicular to the surface of the cooler 3. The majority of magnetic flux generated in the coil 6 is curved on the outer periphery of the coil so as to avoid the protrusions 3b, but since the protrusions 3b are distributed to the opposite sides of the winding axis CL, nonuniformity of magnetic flux is reduced. 【課題】コイルの周囲を覆うコアに冷却器が接しており、コアを貫通しており冷却器とコイルに接する伝熱部材を備えるリアクトルにおいて、磁束の不均一性を小さくする技術を提供する。【解決手段】リアクトル200は、コイル6を埋設しているコア4とコア4に接している冷却器3を備えている。リアクトルはさらに、コア4を貫通しており、一端が冷却器3に接しているとともに他端がコイル6に接しており、コイルの巻回軸線CLの方向に細長い一対の突部3b(伝熱部材)を備えている。一対の突部3bは、コイル6の巻回軸線CLを通り冷却器3の表面に垂直な平面を挟んでその両側に分散して設けられている。コイル6に発生する磁束の多くはコイル外周で突部3bを避けるように湾曲するが、突部3bが巻回軸線CLの両側に分散しているので、磁束の不均一性が低減される。【選択図】図2
