PROBLEM TO BE SOLVED: To provide a reactor which prevents tearing of a heat transfer sheet between a coil and a cooling plate.SOLUTION: A reactor 2 includes: square cylinder coils 12; a resin cover 5; a heat transfer sheet 18; and a cooling plate 22. The resin cover 5 exposes bottom surfaces 12a of the coils 12 and covers the other side surfaces. The coils 12 and the cooling plate 22 face each other and the heat transfer sheet 18 is sandwiched between the coils 12 and the cooling plate 22. The resin cover 5 includes first ribs 31, extending along vertical surfaces 12b, on end surfaces 5b of vertical parts 5a respectively covering the vertical surfaces 12b perpendicular to the cooling plate 22, which face the cooling plate 22. The cooling plate 22 includes second ribs 24, each of which extends parallel to the first rib 31 so as to face the end surface 5b. A tip of each second rib 24 reaches a gap between the vertical surface 12b and the first rib 31. A second rib side end part of the heat transfer sheet 18 curves along the second rib 24 while contacting with a round corner part on a boundary between the bottom surface 12a and the vertical surface 12b.SELECTED DRAWING: Figure 2 |
