The This proposed technology will is expected to enable efficient thermal control by maintaining a constant temperature heat sink or heat source for a wide range of electronic components in rapidly changing thermal environments. The PCM Phase Change Material panel is being designed as a lightweight and flexible component. Even then, yet having it will have high thermal capacity. Thus, requiring it will require less mass and volume than currently presently used carbon-fiber and aluminum honeycomb composite panels. <ref>https://techport.nasa.gov/view/89663</ref><br \>ExExample:<ref>http: PCM //www.puretemp.com/pcmatters/pcm-briefing: Managing heat in low-orbit satellites 110</ref> <br \>Roccor LLC of Longmont, Colo., is using making use of phase change material in a device that is designed to manage internal heat in low-orbit satellites. A product with containing paraffin wax inside within a flat structure i is used. When the spacecraft is hot, it dumps heat into that the paraffin wax acts as a heat sink and turns that into a liquid — basically a store of energy. The Later on, the heat is later released into the satellite to keep temperatures stable. <br \>
