Improving its heat transfer efficiency is something that must be studied. Improving the heat transfer coefficient of equipment is currently the most effective method to enhance its heat transfer efficiency. The total thermal resistance during the heat transfer process determines the size of its heat transfer coefficient. The better the heat transfer effect of the plate finned tube, the higher its heat transfer coefficient, and the lower its total thermal resistance. In order to improve its heat transfer coefficient, many manufacturers use strengthening elements and adopt strengthening measures to improve its heat transfer efficiency, mainly including horizontal corrugated tubes, scaling tubes, threaded tubes, double-sided spiral finned tubes, and added baffles.
