Coolants

Coolants

A coolant is a fluid that prevents overheating of a device. By flowing through or around the device, the coolant transfers the heat produced by that device to other devices that use or dissipate it.

Water as a Coolant
Water, the most common coolant, has high heat capacity and low cost, making it a good heat-transfer medium. Water is generally used with additives, such as corrosion inhibitors and antifreeze. Very pure deionized water, with its relatively low electrical conductivity, is used to cool some electrical equipment, such as high-power transmitters and high-power vacuum tubes. Heavy water, a neutron moderator used in some nuclear reactors, functions secondarily as the coolant. Light water reactors, both boiling water and pressurized water reactors, use ordinary (light) water.

Other Liquid Coolants
Polyalkylene glycol (PAG), which resists oxidation, is used as a high-temperature, thermally stable heat transfer fluid. Cutting fluid is a coolant that is also used as a lubricant for metal-shaping machine tools. Oils that can be used as coolants for specific applications include mineral oils, castor oil, silicone oils and fluorocarbon oils.

Other Coolants
Fuels are commonly used as engine coolants. For aviation engines, coolants include kerosene and other jet fuels. Additional coolants with specific applications are Freon and refrigerant; these are used to reach low temperatures, such as in air conditioners and refrigerators.
