Heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid, also known as heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. The price of heat exchangers in chemical production can be widely used as heaters, coolers, condensers, evaporators and reboilers.

Heat exchanger is a kind of energy-saving equipment to realize heat transfer between two or more fluids at different temperatures. It is one of the main equipments to improve the energy utilization rate and to make the heat transfer from the higher temperature fluid to the lower temperature fluid, so that the fluid temperature can meet the process requirements. The heat exchanger industry involves more than 30 industries, such as HVAC, pressure vessel, reclaimed water treatment equipment, chemical industry, petroleum industry, and so on. Data show that the market size of heat exchanger industry in China in 2010 is about 50 billion yuan, mainly concentrated in petroleum, chemical industry, metallurgy, power, ships, central heating, refrigeration and air conditioning, machinery, food, pharmaceuticals and other fields. Among them, petrochemical industry is still the largest market of heat exchanger industry, with a market scale of 15 billion yuan; electric power metallurgy heat exchanger market scale of about 8 billion yuan; ship industry heat exchanger market scale of more than 4 billion yuan; machinery industry heat exchanger market scale of about 4 billion yuan; centralized heating industry heat exchanger market scale of more than 3 billion yuan, food industry also has nearly 3 billion yuan. Market. In addition, a large number of specialized heat exchangers are needed in the fields of spacecraft, semiconductor devices, nuclear power conventional island, wind turbine, solar photovoltaic power generation, polycrystalline silicon production and so on. These markets have a scale of about 13 billion yuan. The domestic heat exchanger industry has made remarkable achievements in energy saving and efficiency enhancement, heat transfer efficiency improvement, heat transfer area reduction, pressure drop reduction and heat intensity improvement. Based on the steady growth of demand for heat exchangers in petroleum, chemical, power, metallurgy, shipping, machinery, food and pharmaceutical industries, China's heat exchanger industry will maintain a steady growth in the coming period. From 2011 to 2020, China's heat exchanger industry will maintain an average annual growth rate of about 10-15%, and the scale of China's heat exchanger industry is expected to reach 150 billion yuan by 2020.
