MAIN IDEA: to minimise weight and dimensions of cooling and heating for avionics

Loop heat pipes (LHP) proved their worth in thermal control systems of spacecraft. Moreover, they can be the perfect solution for avionics thermal control.

60% of avionics failures are the result of thermal control system malfunction

Thercon-LHP loop heat pipes advantages:
  • high heat transfer capacity (heat transfer distance up to 2,000 cm, transferred power up to 2,000 W);

  • compactness, adjustablility, light weight;

  • low heat transfer energy consumption (passive element);

  • any orientation in space (low sensitivity to gravity);

  • noiselessness;

  • high reliability and extended working life;

  • stable operation in a broad range of temperatures (from -50ºС up to +100ºС)

  • no scheduled maintenance required.

Projects for avionics:

  • Under the cooperation with Thales Avionics in terms of COSEE and PRIMAE projects, Thercon-LHP is developing loop heat pipes for avionics. Loop heat pipes with freon as a working fluid are integrated in the experimental cooling system of the control unit onboard of long-range aircraft. Thanks to passive LHP-based heat sink, fans and their noise were eliminated. Besides, energy consumption was reduced to zero.
