This causes severe discrepancies in the temperature (and thus reliability and accuracy) of the transponders. Thermosyphons, which only transfer heat from the bottom to the top of the thermosyphon, where the condensate returns by gravity. The most commonly used envelope (and wick)/fluid pairs include:. A Vapor Trap Diode is fabricated in a similar fashion to a Variable Conductance Heat Pipe (VCHP), with a gas reservoir at the end of the condenser. During fabrication, the heat pipe is charged with the working fluid and a controlled amount of a Non-Condensable Gas (NCG). Above the evaporator, the flange is machined off to allow the adiabatic section to be bent. Heat pipes contain no mechanical moving parts and typically require no maintenance, though non-condensable gases that diffuse through the pipe's walls, resulting from breakdown of the working fluid or as impurities extant in the material, may eventually reduce the pipe's effectiveness at transferring heat. World Nuclear Association. Non-condensing gases (caused by contamination for instance) in the vapour impede the gas flow and reduce the effectiveness of the heat pipe, particularly at low temperatures, where vapour pressures are low. Loop heat pipe.
