A specialist trained through fusion research has helped transfer advanced thermal and mechanical design methods into the development of compact heat exchangers for industrial energy systems. The original expertise came from work on plasma facing components exposed to severe thermal fatigue and high heat loads, where engineers had to understand how materials, cooling systems and mechanical stresses interact under extreme conditions.

Outside fusion, this know how has been applied by a French technology company developing high performance heat exchangers for sectors such as aerospace, defence, automotive and energy. The transfer did not rely on a single product. It involved methods used every day, from thermal modelling and mechanical design to material selection, manufacturing choices, prototyping and validation.

The value of this transfer becomes clear in demanding projects where heat exchangers must operate at very high pressure and temperature, in some cases around 250 bar and above 550°C. Under these conditions, creep, fatigue and corrosion can strongly affect performance and lifetime. Experience gained in fusion made it possible to analyse these risks early, optimise internal structures, and validate the mechanical behaviour of critical parts before production.
