Abstract

Analytical techniques have been developed which characterize the heat transfer between a surface and an ambient air stream when the surface is augmented by fins attached with an adhesive. An air side efficiency criterion is introduced which accounts for the thermal resistance of the adhesive. The analysis is applied to finned tubes, and experimental results are presented. Air side efficiency comparisons between interference-fit fins and adhesive-bonded fins show that adhesive-bonded fins perform as well as interference-fit fins on a per-contact-point basis. The factors which influence the optimal distribution of fin material in the adhesive-bonded fins are discussed. Finally, the advantages of adhesive-bonded fins are presented, and the impacts of this bonding technique on heat exchanger design are noted.
