Nowadays, aircraft constructors are working on innovative solutions to minimize fuel consumption. In this context, power electronics components, supplying eMotors, should be cooled as efficiently as possible. A study of high efficiency cooling systems is proposed in this work. The purpose is to find the most performing and efficient cooling solution to allow power electronic converters to operate with the highest performances possible for a hybrid propulsion aircraft. After a study focused on the most suitable solutions, this work aims to compare and highlight limits and potentialities of different cooling systems adapted for this particular application field. A focus is made on a specific passive capillary pumped system because of its performances and energetic efficiency: the Capillary Pumped Loop for Integrated Power (CPLIP). Previous numerical and experimental results show the performances of this loop, able to ensure the temperature requirements for power modules: the temperature map of power converter modules meets the specifications. Other than the capability to ensure the temperature controllability, it will be shown how this loop is able to go beyond the required power-to-mass ratio to allow these systems to fly.
