How to design a flat plate heat sink | Heat Sink ...

A heat sink is a part that conducts heat from a heat generating component to a larger surface area to dissipate the heat to the surroundings thus reducing the temperature of the component. Based on this definition anything from a rectangular sheet of metal to a complex finned copper or aluminum extrusion can be used as a heat sink. In situations where there is ample space and/or the heat dissipated by the component is low an aluminum or copper plate can be used as an effective heat sink.

heatsink - Does the paint colour matter on a heat sink ...

Oct 11, 2017 · Do not paint heat sinks. The layer of paint will act as an insulator between the metal and the air, reducing its ability to dissipate heat. Anodizing a heat sink is less of an issue. The anodization layer is much thinner than paint (a few micrometers in aluminum, for instance), so it presents a much lower thermal resistance than paint would.
