Heatsinks

Friction stir welding is of great value when producing heat sinks made of aluminum, cast or milled components. Many areas and industries require heat sinks, including power electronics, for example. Heat sinks are essential in high-performance applications, as they regulate power semiconductors like IGBTs. Cooling lithium-ion accumulators for electric vehicles are another example.

Heat sinks and cooling elements enlarge the surface of the heat-generating component, so that more heat can be emitted through the surface. This prevents overheating.

Heat sinks have to fulfill several requirements to work properly. They need to be made of heat-conductive material; they should be mounted vertically so that they can enhance air circulation (chimney effect), and their surface area should be dark and as large as possible.

Heat sinks comprise air- and water-filled cooling elements, with water components emitting more heat in relation to size.
