✦ Synopsis

The optimum dimensions of convective radiating extended surfaces or ®ns have been determined. Several ®n shapes, pro®les, have been analyzed including those treated by Gardner (Trans. ASME 69 (8) (1945) 621±631). Consideration is given to radiating ®ns and convective±radiating ®ns. In addition the cases of non-zero temperature sink, and the in¯uence of the temperature dependent thermal conductivity and emissivity have been investigated. The results are generalized by expressing the ®n's optimum thickness, height, and heat dissipation in dimensionless form. They are presented graphically and in polynomial form the latter being particularly useful for computerized calculations.
