Power electronics generate heat. This heat is not good for the electrical components in power electronics system and therefore it needs to be removed from the system. There are practically two principal methods to remove the heat from the system.

Traditionally air has been used to remove the heat. The process principle is simple: air is circulated or blown through the heat generating system. The heat is practically blown away. Air cooling system requires an air circulation system with ducts and vents, a fan unit to move air and a cooler unit to cool down the heated air before it goes back to circulation.

The other alternative to remove the heat is to use water. Here the process is simple as well: the heat source has heat sinks or elements that can be cooled with water. Cold water is circulated to the heat source and heated water is the lead out and cooled with a water-to-water heat exchanger or with a water-to-air cooler. Water cooling system requires a pipesystem, pimpstation and water-to-water heat exhanger or with water-to-air cooler units.
