Serrated finned tubes stand out as a specialised category of heat exchanger tubes crafted to enhance the efficiency of heat transfer processes. What sets them apart is the incorporation of serrations – small notches or grooves along the fins. These serrations are strategically designed to disrupt the air or gas flow boundary layer over the finned surface, leading to improved heat transfer characteristics.
