A heat dissipation plate that protrudes from a flat mounting surface, and has a recess formed along the protrusion at a corner formed by the contact surface of the heat-generating component of the protrusion and the mounting surface.

Claims

[Scope of utility model registration request]

In a heat dissipation plate formed by extrusion molding, in which a heat generating component with restrictions on the installation direction is screwed, the protrusion that the left end of the heat generating component comes into contact with is attached to a flat mounting surface that closely contacts the heat dissipating surface of the heat generating component. A heat dissipation plate that is provided in a protruding manner and has a concave portion formed along the protruding strip at a corner formed by the contact surface of the heat-generating component and the mounting surface of the protruded strip.
