Weight consideration of liquid metal cooling technology for power electronics converter in future aircraft

Cooling system becomes a serious concern due to weight and volume contribution of power electronics system in aerospace sector. This research investigates the contribution of cooling system to the total weight of power electronics converter when liquid metal cooling is applied. In addition, it is compared with the traditional working fluid (water). It is concluded that cooling system could be much lighter if the liquid metal cooling is introduced. In this study the introduction of liquid metal cooling results in 12 times lighter pump.
