Heat sinks

Attached to mechanical or electrical components that generate heat, in order to dissipate the heat and lower the temperature. For improving the performance of heat sinks, they are formed into shapes that provide large surface areas, such as shapes resembling pinholders or bellows using plates or pins (generally referred to as fins). Aluminum, copper, and other highly thermally conductive materials are mostly used. A heat sink is made by extruding metal under high pressure, or by assembling terminals to a flat metal plate.
