Heat exchangers are commonly used in industrial production, such as petroleum, chemical, light industry, pharmaceutical, and energy, to heat low-temperature fluids or cool high-temperature fluids, and to vaporize liquids into steam or condense steam into liquids.
A heat exchanger can be a single unit of equipment, such as a heater, cooler, or condenser; or it can be a component of a process unit, such as the heat exchanger in an ammonia synthesis tower. Heat exchangers are crucial unit equipment in chemical production. Statistics show that the tonnage of heat exchangers accounts for approximately 20% of the total tonnage of the entire process equipment, and in some cases as high as 30%, highlighting their importance.
