Optimized heat sink for power supply unit has diagonal notch in heat sink for receiving heat-resistant folded sheet metal to which finned body is attached

摘要

An aluminum finned body is formed as a T-shaped heat sink block, comprising a central plate and multiple cooling fins supported at right angles. An oblique notch is cut in the transverse direction of the heat sink, and receives a heat-resistant piece of folded sheet metal of the same width. From a fold line onwards, the horizontal upper part of the sheet metal is stuck to the upper surface of the T-shaped aluminum finned body.
