The copper foam is coated with a thin, hard layer of high temperature copper oxide, which improves its emissivity and therefore further improves heat sink thermal performance. The material, which is the result of metallurgy research at the University of Liverpool’s Department of Engineering, allows the heat sinks to provide a thermal efficiency of up to 6ºC/W cooler than competing devices. This increased efficiency allows the heat sinks to be air cooled rather than fan cooled and increases the lifespan of components by reducing overheating.
Suitable applications include power ICs, high temperature components and transistors, STBs, AP routers, cable modems, optical networks, LED TVs and flat panel displays.
