The inner finned tube is a new type of high efficiency heat exchange tube which appeared in China at the end of the 20th century. Internally finned tube heat exchanger is a new type of heat exchanger developed and produced according to the characteristics of gas-liquid heat transfer. Its design changes the traditional design method. By adding internal expansion fins inside the heat exchange tube, the heat exchange area on the air side (inside the tube) is increased, and the total heat transfer coefficient is improved. The problem of heat exchange imbalance caused by different thermal conductivity of heat exchange medium is effectively solved, The energy saving effect is remarkable and the consumption of cooling water is reduced. The internally finned tube has the advantages of good strengthening effect, high fin efficiency, high technical content, and no large pressure loss. It is a new high-efficiency and ideal gas heat exchange element in China.

Internally finned tube heat exchanger is mainly used in petroleum, chemical, pharmaceutical, metallurgy, power, power, refrigeration, heat pump, food and other industries.

The main working conditions are as follows:

(1) cooling and heating of various process gases;

(2) condensation of various process gases;

(3) recovery, cooling and condensation of tail gas of various process gases;

(4) high (low) viscosity liquid and water heat exchange;

Inner finned tubes advantages

1. The heat exchange efficiency is greatly improved, and the effect of energy saving and water saving is remarkable

2. It can withstand high temperature and high pressure with low resistance drop

3. The heat exchanger has small volume and small floor area

4. Low investment and short return period

5. Reduce the maintenance cost of users
