About
Contour Heat Pipes (CHPs) are hermetic, closed, two-phase (vapor/liquid) thermal transfer systems filled with a working fluid, typically Ammonia or Propylene. Their primary purpose is the thermal control of spacecraft equipment. Key advantages of CHPs include a design that allows for active and passive control of their performance, the ability to operate in any arbitrary position within a gravity field, and small pipe diameters that enable bending of transport lines, significantly simplifying integration into spacecraft. CHPs can also integrate various condenser designs, such as radiators, flow heat exchangers, and contact saddles. The product was released in 1992 and boasts a guaranteed service life of 25 years after filling with working fluid. It has extensive flight heritage, having operated successfully on board more than 30 Russian and foreign satellites. The manufacturer offers the possibility to adapt the product to customer requirements.
