AI Technical Summary

Technical Problem

Existing heat exchange devices are large in size due to the flanges on the inner and outer water seal plates, which affects the miniaturization of combustion heat exchange modules and gas-fired hot water equipment.

Method used

By setting upper limit sections on the inner and outer water seal plates and eliminating the folded flange edge, relative movement is prevented through the limit sections, thus reducing the size of the heat exchange device and the smoke hood.

🎯Benefits of technology

While ensuring pressure resistance, the size of the heat exchange device and the smoke hood has been reduced, thus lowering the cost and achieving miniaturization of the combustion heat exchange module and the gas-fired hot water equipment.
