How a heat pipe works
WebSpacecraft heat pipes are usually under 10 feet (3 m) long, and the extra length is allowed because they operate in zero gravity. When a heat pipe works with gravity, called a thermosyphon, the length can be virtually unlimited, and you’ll find many in lengths up to hundreds of feet (m). Can a heat pipe operate against gravity? WebThe passive operation of Heat-pipes requires no external motive power except that of the applied temperature differential “ r T” provided by the thermal loading. Having no moving …

WebHeat pipes have become an indispensable part of modern thermal management systems: thanks to their extremely high thermal conductivity of 5,000 to 20,000 W/mK due to vaporisation heat, they can be used to replace metallic conductors such as copper very effectively and make decentralised cooling possible. WebA loop heat pipe (LHP) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator.LHPs are …
