Heat transfer equipment industry is in golden growth period and the application is very extensive
Heat exchanger is a device which is transferred the heat fluid to the cooling fluid, and also known as the heat exchanger. Heat exchanger is the general equipment in chemical, oil, steel, automotive, food and other industrial sectors with very important position during production. Especially in chemical production, the heat exchanger can be widely used as heater, cooler, condenser, evaporator, and so on.
In recent years, with the rapid development of Chinas petrochemical, steel and other industries, the demand for heat exchanger has risen sharply, but the supply capacity of domestic enterprises is limited, which leads to the shortage of the heat exchanger industry. The huge supply gap needs to be imported.
In twentieth Century 20s on the heat exchanger, and the application in food industry. Made in escrow heat exchanger, compact structure, good heat transfer effect, thus gradually developed a variety of forms. In the early 30s, Sweden was first made into a spiral plate heat exchanger. Then the British made of copper and its alloy material made of a plate fin heat exchanger, which is used to heat the engine. At the end of the 30s, Sweden has made the first plate heat exchanger, used for pulp factory. During this period, in order to solve the problem of heat transfer in the medium of strong erosion, people made of new materials for the heat exchanger began to pay attention.
Around the 60s, because of the rapid development of space technology and cutting-edge science, the urgent need for a variety of high performance compact heat exchangers, and stamping, welding and sealing technology development for heat exchanger manufacturing process has been further improved, so as to promote the compact plate type for the rapid development and wide application of heat exchanger. In addition, since the beginning of the 60s, in order to adapt to the high temperature and high pressure conditions of heat transfer and energy saving needs, a typical tube shell heat exchanger has been further developed. In the 70s, in order to strengthen heat transfer, the heat pipe heat exchanger was created on the basis of the research and development of heat pipe.
In recent years, the domestic heat exchanger industry in energy efficiency, improve the heat transfer efficiency, reduce the heat transfer area, reduce the pressure drop, improve the thermal strength of the research has achieved remarkable results. Based on the growth in the demand for petroleum, chemical, electric power, metallurgy, shipbuilding, machinery, food, pharmaceutical and other industries heat exchanger stability, in China for the industry in a period of time in the future will maintain a steady growth, by 2020 China change the industry scale is expected to reach 150 billion yuan. At present, the national heat transfer equipment market is in short supply of the market, the heat exchange equipment industry is in a golden period of growth.
