Pure aluminum heat sink

Increasing demands on device performance combined with miniaturization are leading to higher packing densities of electronic components. This is increasingly causing problems with heat dissipation, although efficiency is increasing in most applications. The locally generated heat is dissipated via heat sinks, for which less and less installation space is available.

However, optimum cooling is very important because temperature has a major influence on the service life of electronic components. For example, a rule of thumb states that reducing the temperature by 10 K doubles the service life. For this reason, solutions are being sought to make heat sinks more effective and more individual without breaking the budget. An important role is played by the choice of materials …
