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 circuit. This means that the facility does not only reject the heat, but also the water which contains the heat to allow an external party to transport and use the warmed-up liquid. This results in a complete lack of cooling installations and the datacentre effectively acts like a large water heater. Water flows into the datacentre and comes out at high temperatures. The ILC racks in this setup effectively function as air handlers which maintain the entire room temperature and absorb all thermal energy leakage from the DLC and TLC environments. In smaller footprints, temperature chaining can be achieved by
