| description | Extended surface technology, as a key passive approach for enhancing heat transfer of heat exchangers, has shown significant potential in a wide range of thermal management applications. This review aims to establish a systematic framework for extended surface technology applied in heat exchangers. All types of heat exchangers are classified and introduced according to the structural features of the heat transfer surface. The flow and heat transfer mechanisms of extended surface technology are elaborated. Furthermore, recent advances in passive heat transfer enhancement using extended surface technologies encompassing different fin types, such as straight fins, longitudinal fins, radial fins, annular fins, helical fins, pin fins, wavy fins, offset-strip fins, and louvered fins, as well as turbulators based on extended surface technologies, including ribs, blocks, baffles, and other vortex generators are systematically examined. The influence of fundamental geometric parameters on flow and heat transfer characteristics is thoroughly evaluated. The effectiveness of various geometric optimization strategies in enhancing heat transfer performance and controlling flow resistance and pressure drop is systematically discussed, such as perforation, corrugation, segmentation, and interruption. Finally, the potential research directions in extended surface technology for future investigations are proposed. |
