The nonlinear fin equation in Spherical coordinates is studied in this paper. Classification of temperature dependent thermal conductivity and radial variable heat transfer coefficient is performed via Lie symmetry analysis. Using these symmetries, nonlinear fin equation in spherical coordinates has been transformed into an ordinary differential equation. An Exact solution of this ODE is obtained whenever possible.
