The liquid or gas used to transfer the heat of nuclear fission to a heat-exchanger in which steam is raised for the electrical turbine-generator. The cool liquid or gas is then returned to the reactor. The coolant for the PWR is highly purified water.
cutting fluid A special liquid that performs three main functions during machining: It lubricates the cutting action, cools the cutting action, and flushes the chips. Two general types of cutting fluid are available: standard oil and soluble oil.
a fluid agent (gas or liquid) that produces cooling; especially one used to cool a system by transfering heat away from one part to another; "he added more coolant to the car's radiator"; "the atomic reactor used a gas coolant"; "lathe operators use an emulsion of oil and water as a coolant for the cutting tool"
A liquid used to dissipate heat in the saw band and work piece. The term often is used loosely as a synonym for cutting fluid encompassing the concept of lubricating properties as well as cooling effects.
The liquid located in the cooling system and engine used to dissipate heat. Engine coolant prevents freeze-up in winter, reduces the engine temperature in the summer, and protects the cooling system from rust and corrosion year round.
Fluid, usually a liquid such as water or water/glycol mixture (anti-freeze), used in a cooling system for an engine that picks up heat from the engine and transfers it to the air passing through the radiator.
is a soup of ingredients that have been specially blended by your coolant supplier. Two of the ingredients are rust inhibitors and anti-emulsion agents. It has been particularly designed to work with pure water at a specific concentration. It is, in fact, a type of oil. In this way your machine has the best of both worlds; the lubricity of oil plus the cooling qualities of water (see oils below). It also contains emulsification agents, among other things. Coolant is also called industrial cutting fluid.
A traditional name for metalworking fluids used in grinding. Once thought as primarily a means to cool a workpiece to prevent burn, research showed that fluids have other functions such as lubrication, which may be equally or more important than cooling. Hence the preference for the use the terms metalworking fluids to refer to fluids used in grinding processes.
A substance used to cool the reactor and to slow neutrons. In most nuclear power plants, water is used for cooling to keep the reactor from getting too hot and to slow neutrons down so they are more likely to cause uranium-235 to fission. The most common coolants are water and heavy water. See; Light-Water Reactor, Pressurized-Water Reactor, Reactor.
A solution that raises the boiling point and lowers the freezing point of the water in the cooling system, prevents rust and corrosion, and lubricates the system components. It is often called antifreeze.
Usually misnamed inhibitor. A true coolant may have very little corrosion inhibitors in it, but will raise the boiling point, carry heat away from hot spots and exponentially lower the water temperature, ie:- the hotter the engine runs the better the coolant keeps the temperature down, might lower it 2 deg. at 90 deg. but 6 deg at 120 deg.
A mixture of water and antifreeze (ethylene glycol) which lowers the freezing point of the water in the cooling system, prevents rust and corrosion, lubricates the water pump, and picks up heat from the engine, transferring it to the air passing through t
The mixture of water and anti-freeze that picks up heat from the engine and transfers it to the air passing through the radiator. This transfer of heat keeps the engine operating within its optimum temperature rant preventing premature engine wear.
A coolant, or heat transfer fluid, is a fluid which flows through a device in order to prevent its overheating, transferring the heat produced by the device to other devices that utilize or dissipate it. An ideal coolant has high thermal capacity, is low-cost, and is chemically inert, neither causing nor promoting corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
