Fin Tubes----The New Methods of Enhanced Heat Transfer for Finned Tubes of Air-Cooled Heat Exchangers
This article formulized the newmethodsof enhanced heat transfer for finned tubes of air- cooled heat exchangers,and introduced the construction and manufacturingtechnology of the new type of finned tubes. Compared the characteristics of heat transfer and frictional resistance of the new type of finned tubes with that of traditional finned tubes, and the corresponding curves and experimental formulae of heat transfer coefficient and frictional resistance were given. It was manifested that after the traditional finned tubes was improved, the effictiveness of heat transfer was visibly enhanced, both in environmental protection and energy conservation, the new type of finned tubes had high value in engineering. Pointed out the necessary considered factorson the selection and manufacture of new type of finned tubesof air- cooled heat exchangers.
