Abstract

The PC-boards are contained in sealed enclosures, and serially effective heat pipe systems conduct thermal energy from the respective sources of development (e.g., power transmitters) to the top and from there to a heat pump system. Stacking such units and operating the heat transfer partially in parallel is disclosed.
