Structure for Cooling Heat Generator and Power Conversion Equipment

摘要

The disclosed invention provides power conversion equipment in which the thermal resistance of thermal connections is reduced. A structure for cooling a heat generator includes a heat generator having at least one cooled surface having protruding convex portions formed thereon, a heat receiving spacer in which hollow portions into which the convex portions are inserted are formed, clamping members which press and clamp the heat receiving space and the heat generator sandwiched therebetween, and a cooler which cools the heat receiving spacer. In an engagement state in which the heat generator and the heat receiving spacer are engaged by the clamping members, a distance between the cooled surface and the end faces of the convex portions is smaller than a distance between the cooled surface and a face, facing either of the clamping members, of the heat receiving spacer.
