Heat exchanger, also known as heat exchanger, is a device that transfers part of the heat of hot fluid to cold fluid. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. It can be widely used as heater, cooler, condenser, evaporator and reboiler in chemical production.

Heat exchanger is an energy-saving equipment that can transfer heat between materials between two or more fluids at different temperatures. It is used to transfer heat from the fluid with higher temperature to the fluid with lower temperature, so that the fluid temperature can meet the requirements of process conditions, and it is also one of the main equipment to improve energy utilization. The heat exchanger industry involves more than 30 industries, such as heating and ventilation, pressure vessels, reclaimed water treatment equipment, chemical industry, petroleum, etc., forming an industrial chain with each other. The data shows that the market size of China's heat exchanger industry in 2010 was about 50 billion yuan, mainly concentrated in the fields of petroleum, chemical industry, metallurgy, electricity, shipbuilding, central heating, refrigeration and air conditioning, machinery, food, pharmaceuticals, etc.
