Heat pipes also known as thermosyphons were initially developed for use in the space industry but are now widely used across the electronics and industrial sectors.

Heat pipes work on a refrigeration cycle to provide greater cooling capacity and closer approach temperatures than otherwise available with a traditional air cooled system. The thermosyphon works on a fully enclosed system with no moving parts using differential pressure to drive the refrigerant from the condensation to evaporation end of a sealed tube.

The condensation end of the heat pipe is subjected to the higher temperature causing the contained refrigerant to boil and due to the differential in pressure this causes the resulting vapour to rise to the top of the tube where cooler air is passed over the tube and the refrigerant condenses and returns back to the condensation end.

  • Close approach temperatures
  • Wide Range operating Temperatures
  • Compact Design

Avantair (Sterling Thermal Technology’s derivative of the heat pipe) was conceived in 1998 as a low maintenance and efficient cooler for the wind turbine and generator market.

The combination of the very effective HEI block fin together with the extremely efficient thermosyphon technology was a winning combination. The resulting ‘Avantair’ cooling system is a closed circuit, generator mounted, cooler that is compact, economic and capable of close approach temperatures.

The Avantair product has been successfully used to upgrade open circuit machines to close circuit operation, reducing maintenance and extending life; as an alternative that is more compact than the traditional CACA cooler and as a ‘plug and play’ alternative to complex water cooled solutions.

Avantair offers considerable savings in project time and cost over every available alternative, whether the scope is new build or refurbishment.

We are always looking for new applications to apply heat pipe technology to If you think you have an application that could benefit from this technology big or small please get in touch and we would be happy to discuss this with you further.
