The internally expanded finned heat exchanger tube is a new type of heat exchanger tube that emerged in China at the end of the 20th century, and has been reported for more than 20 years in foreign countries. The internally expanded finned tube heat exchanger is a new type of heat exchanger developed and produced for the characteristics of gas-liquid heat exchange. Its design changes the traditional design method by adding internally expanded fins inside the heat exchange tube, increasing the heat exchange area on the air side (inside the tube), improving the overall heat transfer coefficient, effectively solving the problem of heat exchange imbalance caused by different thermal conductivity coefficients of the heat exchange medium, achieving significant energy-saving effects, and reducing the consumption of cooling water. The internally expanded finned heat exchanger tube has excellent characteristics such as good reinforcement effect, high fin efficiency, high technical content, and does not produce significant pressure loss. It is an emerging and ideal gas heat exchanger component in China.
Internal finned tube heat exchangers are mainly used in industries such as petroleum, chemical, pharmaceutical, metallurgy, power, refrigeration, heat pumps, and food. The main applicable working conditions are: (1) cooling and heating of various process gases; (2) Condensation of various process gases; (3) Recovery, cooling, and condensation of various process gas exhaust gases; (4) Working conditions such as high (low) viscosity liquids and water heat exchange;
1. The heat exchange efficiency is greatly improved, and the energy-saving and water-saving effects are significant
2. Able to withstand high temperature and pressure with low resistance reduction
3. The heat exchanger has a small volume and occupies a small area
4. Low investment cost and short return period
5. Reduce maintenance costs for users
