The Basic Principle Of Heat Transfer in Finned Tubes

Finned tubes increase the heat transfer area by adding fins outside the tube, thereby improving the heat transfer efficiency of the heat exchanger. During the heat exchange process, heat is transferred to the fins through the outer wall of the finned tube, and then to the fluid through the fins, achieving heat transfer and exchange. The heat transfer efficiency of finned tubes is influenced by various factors, including the shape, size, material, fluid properties, flow rate, etc. of the fins.
