6.2.1. Passive cooling

Passive cooling module

Example of passive cooling for the module

Heat transfer from a heat source to the surrounding cooling medium (e.g. air) depends primarily on the difference in temperature, the
effective surface area and the flow rate of the cooling medium. The function of a heat sink is to increase the surface area over which
the heat can be dissipated. This lowers the thermal resistance.
A passive heat sink works mainly by convection. The surrounding air is heated, which makes it rise, and is replaced by cooler air.
Heat pipes can be used as an alternative to cooing with fans. If space is particularly tight, the heat is first conveyed away. The actual
heat sink is located at the other end of the heat pipe.
