Client Challenge_jaune2.png

  • Optimise product’s TCO with thermal hot spot issue

  • Create a thermosiphon able to operate, passively (no check valve) with evaporators located anywhere with respect to condenser

  • Use thermal inertia of the heat sink to smooth thermal overload required by the norms

  • Minimize the fluid inventory thanks to 5 mm IGT copper tubes

  • Full power startup

  • Achieve 0.05 K/W at power module level
