Thermal fluid is a type of liquid or gas used to transfer heat in various industrial processes. It is designed to operate at high temperatures and can efficiently carry thermal energy from one location to another. Common applications include heating systems, chemical processing, and power generation. These fluids can be organic or inorganic and are often chosen for their thermal stability and low viscosity. Examples of thermal fluids include water, oil, and specialized synthetic fluids. Proper selection of a thermal fluid is crucial for optimizing energy efficiency and ensuring safe operation in systems like heat exchangers and solar thermal collectors.
