Problems solved by technology

[0002] At present, the structure of the finned tubes produced is mostly in a spiral shape. It is made of elongated metal sheets with good thermal conductivity and welded to the metal tubes by winding methods, embedding methods, folding embedding methods and embedding welding methods. Together, a spiral-shaped finned tube is formed to improve heat exchange efficiency by increasing the area of ​​heat conduction. This method does not eliminate the gap between the two bodies well. This gap is the key to hindering heat exchange, so its The heat exchange rate has always been low, coupled with the insurmountable winding stress and the different expansion coefficients of the two bodies, the gap gradually increases until the two bodies are separated, so the service life is short; the method of embedded welding is adopted, although the use of titanium powder buried welding is higher than that of high frequency The welding is good, but the cost is expensive, the process is complicated, and the problem of gap resistance still exists
