Abstract
The increasing power density of electronic devices and components requires the development of new cooling methods and systems by which large heat fluxes can be dissipated. One method is to transport the heat from a heat source to the cooling system. To increase the efficiency of such heat transfer and cooling systems, high thermally conductive materials have to be developed. At present, a commonly used material for heat transport applications is Aluminium. Aluminium has high mechanical stability, low weight but also a medium high heat transfer coefficient of 180 W/(m?K) (for A356). Monocrystalline Diamond with more than ten times higher thermal conductivity than Aluminium could offer an additional solution for thermal transport applications. By combining Aluminium and monocrystalline Diamonds to composite materials, the positive properties of each material can be used. Therefore, an Aluminium Matrix composite (AMC) reinforced with monocrystalline Diamond particles was created.
