 Heat exchanger as a heat transfer equipment, is widely used in oil refining, chemical, light, and heat exchanger, the city's central heating and other fields. Especially since the 1970s, as the world's growing recognition of the energy crisis, the heat exchanger design, manufacture, structure and heat transfer mechanism of improvement has never been interrupted, national science and technology workers are looking for ways to save energy, One heat exchanger and heat exchanger components of the research, development more and more attention has been paid. Especially in computer applications, not only saves a lot of manpower, material resources, improve efficiency, but also can be the optimal design and control, to achieve the best technical and economic performance. With the continuous development of science and technology for a variety of conditions of different structures heat came into being, and in heat transfer equipment in the most widely used shell and tube heat exchanger, it is relatively easy to clean, wearing A easy to replace parts, especially the structure to allow this type of heat exchanger to meet almost all occasions, including special low-and relies on other high pressure and temperature, large temperature difference, evaporation and condensation as well as severe pollution and corrosive fluid situation . However, this low evaporator coils coefficient, which determines its large volume. Meanwhile, the heat exchanger block easy to scale and easy to clean, maintain larger workload. The late 1960s, China made a unique new highly efficient plate heat exchanger of the umbrella, it only has the general characteristics of plate heat exchangers (compact and light weight, heat transfer coefficient, etc.), but also has spiral channel Jianyou spiral plate heat exchanger of some of the features (to reduce dirt deposit, no scale). In recent years, aluminum and aluminum alloy brazing technology continues to improve, prompting another new compact and efficient heat exchanger, the plate-fin heat exchangers are widely applied. But several heat exchanger has its own limitations, can not be used for high flow, high temperature and pressure as well as serious dirt and corrosion of the occasion, so in petroleum, chemical and other important areas of application is still limited. The recent increase in many years, heat pipe technology continues to improve, making the heat pipe heat exchangers in industrial production has been the rapid development of applications, but its manufacturing process more complicated, and thus to some extent limited its wide range of applications in the industrial field.
In recent years, corrugated tube heat exchanger, marking the arrival of a change in the field of heat transfer. It is the elasticity and heat transfer technology, the two disciplines better combination of shell and tube heat exchanger of a profound revolution. It is the original traditional shell and tube heat exchanger based on the structure, with corrugated tubes with a heat exchanger to replace the traditional fluorescent tubes, the fluid in the pipe, tube formation of fully enhanced turbulence, so as to achieve enhanced condenser coils purposes. It inherits the shell and tube heat exchanger durable, safe and reliable, dependable point, use a dry almost all occasions, while overcoming its poor heat transfer, easy plug easy to scale and other shortcomings. Compared with other types of heat exchangers, and its overall performance in the lead.
