Heat exchangers are widely used, such as heating radiators for heating in daily life, condensers in steam turbine devices and oil coolers on space rockets. In petroleum, chemical, light industry, pharmaceutical, energy and other industrial production, heat exchangers are often used to heat low-temperature fluids or cool high-temperature fluids, vaporize liquids into steam or condense steam into liquids. A heat exchanger can be a unit device, such as a heater, cooler and condenser; It can also be part of a process plant, such as a heat exchanger in an ammonia synthesis tower. Heat exchanger is an important unit equipment in chemical production.
