AI Technical Summary

Technical Problem

Existing gas heat exchangers achieve heat exchange between gas and cold/hot media through the inner and outer walls of square tubes, resulting in poor heat exchange efficiency.

Method used

The system uses a metal tube with an air passage and a flange connection to an external gas pipeline. The heat exchange assembly includes an inlet pipe, a manifold, branch pipes, an outlet pipe, and heat exchange fins. The fins are located inside the metal tube, and the gas exchanges heat through the gaps between the fins, avoiding heat exchange between the inner and outer walls.

Benefits of technology

It significantly improves the heat exchange efficiency of gas heat exchangers, with a heat transfer coefficient higher than that of square tube heat exchangers, making full use of the space in metal tubes and saving materials.
