A heat exchanger is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also a key component in improving energy efficiency.
The heat exchanger industry encompasses nearly 30 sectors, including HVAC, pressure vessels, wastewater treatment equipment, chemicals, and petroleum, forming interconnected industrial chains. Data shows that in 2010, the Chinese heat exchanger industry market size was around 50 billion yuan, mainly concentrated in the petroleum, chemical, metallurgical, power, shipbuilding, central heating, refrigeration and air conditioning, machinery, food, and pharmaceutical sectors. Among these, the petrochemical sector remains the largest market for heat exchangers, with a market size of 15 billion yuan; the power and metallurgical sector has a market size of around 8 billion yuan; the shipbuilding industry has a market size exceeding 4 billion yuan; the machinery industry has a market size of approximately 4 billion yuan; the central heating industry has a market size exceeding 3 billion yuan; and the food industry also has a market size of nearly 3 billion yuan. In addition, aerospace vehicles, semiconductor devices, nuclear power conventional islands and nuclear islands, wind turbine generators, solar photovoltaic power generation, and polysilicon production all require a large number of specialized heat exchangers, with a market size of approximately 13 billion yuan. The domestic heat exchanger industry has made significant progress in research on energy saving and efficiency improvement, increasing heat transfer efficiency, reducing heat transfer area, lowering pressure drop, and improving the thermal intensity of equipment. Based on the stable growth in demand for heat exchangers from industries such as petroleum, chemical, power, metallurgy, shipbuilding, machinery, food, and pharmaceuticals, China's heat exchanger industry will maintain stable growth in the future. From 2011 to 2020, China's heat exchanger industry will maintain an average annual growth rate of about 10-15%, and the industry size is expected to reach 150 billion yuan by 2020.
