A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity...

combustion engines are often cooled by circulating a liquid called engine coolant through the engine block, and cylinder head where it is heated, then through...

antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. However, all common antifreeze additives also have lower heat...

notable exceptions being the UK, Japan and Canada). In a PWR, the primary coolant (water) is pumped under high pressure to the reactor core where it is heated...

Waterless coolant is a glycol-based liquid substance that does not contain water. Its boiling point of 191 °C (375 °F) is higher than that of water-based...

A coolant pump is a type of pump used to recirculate a coolant, generally a liquid, that is used to transfer heat away from an engine or other device that...

to that released by burning 2.7 million kg of coal. A nuclear reactor coolant – usually water but sometimes a gas or a liquid metal (like liquid sodium...

A loss-of-coolant accident (LOCA) is a mode of failure for a nuclear reactor; if not managed effectively, the results of a LOCA could result in reactor...

A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators...

purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. Leaks in the head gasket can...
