KULR - Model PCM -Phase Change Materials

An ideal solution for thermal management issues in the Aerospace and Defense industry, as it has a highly effective heat capacity over a small temperature range. This is necessary for a number of applications, including the use of batteries in space, high power lasers, and RF components. Can be particularly useful for compact and high-performance devices that require bursts of computational power in short time intervals. Additionally, we have developed a proprietary high thermal conductivity fiber core material to achieve fast and uniform melting of PCM in any orientation while in low gravity. KULR’s thermal management solution more effectively regulates such high-power conditions thus keeping devices cool.

KULR’s PCM heat sink technology is compact, reliable, and lightweight and has been utilized by leaders in the US aerospace and defense industries. It is inside NASA’s X-38 re-entry vehicle, LEO flight, Mercury Messenger satellite, and NICER telescope on the International Space Station. At current estimates the capacitor has cycled more than 10,000 times without breakage in various applications.
