“coolant”的概念、定义、翻译、参考文献-科学参考

coolant

Physics

A fluid used to remove heat from a system by convection (usually forced), either to control the temperature or to extract energy. In a water-cooled car engine the coolant is water (or water and antifreeze), which is pumped around the engine and cooled in the radiator. In a nuclear reactor the coolant is used to transfer the heat of the reaction from the core to a heat exchanger or to the steam-raising plant. In gas-cooled reactors the coolant is usually carbon dioxide. Pressurized water or boiling water is used as both coolant and moderator in several types of reactor. In fast reactors, liquid sodium is used as the coolant.

Chemical Engineering

A fluid used in a process as a heat transfer medium for extracting heat from one place and transferring it to another. Water is widely used as an effective coolant in heat exchangers due to its abundance, low cost, and high heat capacity. In a nuclear reactor, the coolant is used to remove heat from the core. High-pressure water is used in pressurized water reactors to prevent boiling. Liquid metal-cooled reactors use molten sodium. Mercury has also been used in the past. Gases have been used as coolants; for example, carbon dioxide was used in Magnox and AGR nuclear reactors.
