Liquid metal Liquid metal Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be mercury, but gallium-based alloys, which are lower both in their vapor pressure at room temperature and toxicity, are being used as a replacement in various applications. A few elemental metals are liquid at or near room temperature. The most well known is mercury(Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F). Others include caesium(Cs), which has a melting point of 28.5 °C (83.3 °F), rubidium (Rb)(39 °C [102 °F]), francium
Temperature chaining liquid cooled rack should not be routed to a cooling installation, but to a different type of liquid cooling environment. By chaining the segmented liquid circuits in larger environments, very high return temperatures can be achieved, which enables the practical and effective reusability of thermal energy and decreases investments needed to make large scale heat reuse a viable option. The different liquid technologies can be applied with different temperature levels. There is a difference between normal optimised environments and more “extreme” environments where the solutions and IT equipment are more compatible or specialised for high temperature operation.
