The comparison between twisted tubes and ordinary light tubes shows that the enhancement effect provided by twisted tubes varies in different situations. Therefore, there are no incorrect claims in the industry that claim the enhancement of heat transfer by twisted tubes is a fixed figure: around 30%. Here is a specific operating condition, with calculations for comparison: This is the calculation interface for the optical tube: This is the calculation interface for the twisted optical tube:

Under the condition of the same pressure reduction in the shell side, I provided a comparison of the heat exchanger volumes as well as a comparison of their weights. Clearly, the twisted tube significantly increased the heat transfer film coefficient inside the tube, while also increasing the internal resistance to a much greater extent. Therefore, twisted tubes are more suitable for enhancing heat transfer inside the tube, while the pressure drop within the tube allows for wider operating conditions.
