Wherever electrical power is generated, there is also power dissipation, which heats up the components. This heat needs to be transferred away to prevent overheating. For semiconductors there is a maximum junction temperature, above which the semiconductor ceases to work. The right method to dissipate excess heat heavily depends on the mechanical and environmental conditions, as well as the field of application. Conduction Cooling is a way of transporting the heat without needing fans, and also providing a metal frame makes the solution even more rugged!
