This structure realizes the functions of corrosion resistance, high temperature resistance, high pressure resistance and scale prevention. The fluid channel of other types of heat exchangers is in the form of fixed direction flow, which forms a flow around the surface of the heat exchange tube and reduces the convective heat transfer coefficient.
The biggest feature of scroll hot film heat exchanger is the unity of economy and safety. Considering the flow relationship between the heat exchange tubes and between the heat exchange tubes and the shell, turbulence is not forced by the baffle, but an alternating vortex is naturally induced between the heat exchange tubes, and the due flutter force is maintained on the premise of ensuring that the heat exchange tubes do not rub against each other. The heat exchange tubes have good rigidity and flexibility and will not collide with each other, which not only overcomes the problem of collision damage between floating coil heat exchangers, but also avoids the problem that ordinary shell-and-tube heat exchangers are easy to scale.
High efficiency and energy saving, the heat transfer coefficient of the heat exchanger is 6000-8000 W/m2.0c; All stainless steel, long service life, up to more than 20 years, free replacement of heat exchanger quality problems within ten years; The laminar flow is changed into turbulence, which improves the heat transfer efficiency and reduces the thermal resistance; High heat exchange speed, high temperature resistance (400℃) and high pressure resistance (2.5 MPa); Compact structure, small floor space, light weight, convenient installation, saving civil engineering investment; Flexible design, complete specifications, strong practicability and pertinence, saving money; Wide range of application conditions, suitable for large pressure and temperature range and heat exchange of various media; Low maintenance cost, simple operation, long cleaning cycle and convenient cleaning. Nano-thermal film technology is adopted to significantly improve the heat transfer coefficient. Widely used, it can be widely used in thermoelectric, factories and mines, petrochemical, urban central heating, food and medicine, energy electronics, mechanical light industry and other fields. What is the purpose of tube heat exchanger? The application structure of tubular heat exchanger has the advantages of good corrosion resistance, high temperature resistance, good thermal conductivity, light weight, small floor space, non-toxic, non-scaling, convenient installation and maintenance, wide application and low price. 1980, 10 leading comrades of many chemical units attended. The appraisal opinion holds that the development work in filling modification, secondary molding and special tool welding is successful. It is advanced in China, and it is also the first in making heat exchangers with graphite filled modified polypropylene. What is the purpose of tube heat exchanger? Tubular heat exchanger is characterized by simple and compact structure and low fluid resistance, which can be used to manufacture large equipment, but its pressure resistance and temperature resistance are lower than those of block holes, so it is suitable for occasions where impact and vibration are not strong, and it is better to be used as cooling and condenser. After special treatment, it can also be used as general heating equipment. As a kind of heat exchanger commonly used in chemical industry, tubular heat exchanger has different application scope according to different materials used. Widely used in chemical industry, light industry, metallurgy, pharmacy, food and other industries, the application characteristics are very obvious. Small floor space, non-toxic and non-scaling. When users choose to buy, they should make reasonable choices according to the actual situation.
