Loop Heat Pipe development for severe environment


This topic is focused on a passive cooling device dedicated to the thermal management of valves located inside the A/C engine and therefore exposed to very harsh radiative and convective environment:
- Motor radiative temperature up to 800°C;
- Air through the valve up to 650°C (continuous);
- Local air surrounding the valve up to 300°C.
The objective of this topic is to develop and manufacture the prototype of such a high temperature apparatus and therefore show advantages and drawbacks of the technology in such environment. The specific environment needs an identification of the working fluid that can gather requirements for cooling and satisfy aeronautical safety issues. Thermo-physical properties of this fluid would therefore drive the design of the adapted cooling device. Please refer to the full topic descriptions document published in this call.
