The paper is concerned with a method for solving a steady one-dimentional heat transfer problem of a rectangular straight fin with a temperature-dependent thermal conductivity by regular pertubation. At convection-radiation condition, the constant of fin thermal conductivity variation with temperature and a group parameter consisting of fin thermal conductivity and emission are two small parameters and were chosen as the pertubation parameters. A second-order dual-series pertubation expansion was corried out and solution for the fin temperature and efficiency were presented in terms of a series at an ideal condition of 0 K.
