Coolant

Name:
Coolant
Detailed information:
(heat-transfer medium; thermofor).Any liquid or gas having the property of absorbing heat from its environment and transferring it effectively away from its source. Coolants are used in all types of automobiles, as well as in chemical processing and nuclear engineering equipment. One of the most effective and cheapest coolants is water, which is almost universally used in automotive and ordinary reaction equipment. Air is also used. Where intense heating requires a more efficient medium, special coolants are used: liquid sodium in nuclear reactors, liquid hydrogen in high-thrust nuclear rocket engines; carbon dioxide, propylene glycol, and “Dowtherm” in chemical-processing reactors. Methoxy propanol has been introduced for diesel engines. Some coolants provide antifreeze protection.See Antifreeze.
