BI-PHASE COOLING SYSTEM SUITABLE FOR POWER ELECTRONICS DEDICATED TO MORE ELECTRICAL AIRCRAFT

Objective

"ATMOSTAT has been working for a dozen years on the design of two-phase fluid loops for harsh environments with high density puissance dissipated. We have a very innovative and disruptive technology of loop heat pipes based on mechanical pumping with systems including specific evaporators (high performance process). The measured range of heat flux is better than expected for this type of aircraft application (more than 100W/cm²). Our solution can meet all technical requirements of the CLEANSKY call and we respect the compliance with the expected timetable
Our Loop Heat Pipes iclude at least an evaporator, a condenser, a compact mechanical pump, an expansion vessel, an evaporable fluid, connection pipes and an electronic circuit. The purpose of the project is to develop a practical aeronautic application to reduce drastically thermal contrains, weight and dimensions of high dense power electronics modules (PEM with new wide bandgap materials, for example based on SiC or GaN). The reliability of our solution is guaranteed by the method of design used (APASE®) and the experience of ATMOSTAT in this kind of development (Adequacy and quality of resources, management and implementation capabilities).

A lot of applications will exist in the future dedicated to the aircraft world but also in the world of renewable energies, rail transport, and more generally carbon-free mobilities.We think the project must be a contribution to European competitiveness.
ATMOSTAT is a strategic supplier of the french defense. ATMOSTAT is a industrial subsidiary of ALCEN group (Mid-Sized, 1.800 persons, revenues of 250 million euros). This call is a real opportunity to mature our technology and go to market faster. ."
