Abstract: We consider two related one-dimensional steady-state problems of heat conduction/radiation in a cooling fin. In both problems the solution consists of the value of a parameter (length of the fin) and a monotone temperature distribution in the fin. Three boundary conditions are accordingly imposed: temperature at both ends of the fin and heat flux at one end. We show that these problems have solutions only for data satisfying certain constraints, and we obtain sufficient conditions for existence. Good estimates for the required fin length are also provided.
