Based on more than 35 years of heritage, EHP has manufactured many different heat pipes made of different materials (aluminum, stainless steel, copper, etc.) and working fluids (ammonia, propylene, water, etc.). Based on the latent heat of the working fluid, heat pipes act as highways for the heat. Completely passively, they homogenize the temperature in every point of themselves and allow to transport power.
The working principle is the following:
• In front of the hot source, the liquid is evaporated.
• Then the vapor goes through the pipe to the cold source.
• In front of the cold source, the vapor is condensed.
• The liquid goes back to the hot source because of capillary pressure created by a groove or a mesh and the cycle continues.
In the frame on mega-constallation ongoing project, EHP has developed and qualified a new high capacity heat pipe production line with nominal capacity of 4000 heat-pipes per year.
