Wherever devices and components work in electrical systems, they heat up and produce a lot of thermal energy. As a result, the air in the room heats up even more. In order to avoid overheating, creeping currents and even short circuits, in such systems, it is essential to cool the warm air. Conventional approaches usually only work with climate control units, operating on the basis of the indoor temperature, which requires a disproportionate and tremendous amount of energy.
