what is a heat exchanger?

- Nov 27, 2018-

A heat exchanger is an energy-saving device that transfers heat between materials at two or more fluids at different temperatures. It transfers heat from a higher temperature fluid to a lower temperature fluid, allowing the fluid temperature to reach the flow. The specified indicators meet the needs of process conditions and are also one of the main equipment for improving energy efficiency. 

The heat exchanger industry involves nearly 30 kinds of industries such as HVAC, pressure vessels, water treatment equipment, chemicals, and petroleum, forming an industrial chain. The data shows that the market size of China's heat exchanger industry in 2010 is about 50 billion yuan, mainly concentrated in the fields of petroleum, chemical, metallurgy, electric power, shipbuilding, central heating, refrigeration and air conditioning, machinery, food, and pharmaceuticals. Among them, the petrochemical industry is still the largest market in the heat exchanger industry, with a market size of 15 billion yuan; the market for heat exchangers in the power metallurgy sector is about 8 billion yuan; and the market for heat exchangers in the ship industry is over 4 billion yuan; 

The market size of the heat exchangers in the machinery industry is about 4 billion yuan; the market for heat exchangers in the central heating industry is over 3 billion yuan, and the food industry has a market of nearly 3 billion yuan. In addition, aerospace vehicles, semiconductor devices, nuclear power island nuclear islands, wind turbines, solar photovoltaic power generation, polysilicon production and other fields require a large number of professional heat exchangers, these markets are about 13 billion yuan. 

The domestic heat exchanger industry has made remarkable achievements in energy saving and efficiency improvement, heat transfer efficiency reduction, heat transfer reduction, pressure drop reduction, and heat intensity of the device. Based on the growing demand for heat exchangers in petroleum, chemical, electric power, metallurgy, shipbuilding, machinery, food, pharmaceutical and other industries, China's heat exchanger industry will maintain steady growth in the coming period. From 2011 to 2020, China The heat exchanger industry will maintain an average annual growth rate of 10-15%. By 2020, China's heat exchanger industry is expected to reach 150 billion yuan.
