The thermal conductivity of a material is of paramount importance in space radiators when heat transfer is realized exclusively by radiation. The study deals with a method of solving steady-state radiative heat transfer when the thermal conductivity of a material depends on the temperature. A one-dimensional approximation was used in the analysis. Moreover, it was assumed that the fin had a constant thickness and that the heat transfer into the space was realized by radiation only the effect of the fin and base surface was not considered. Under steady-state conditions, the heat emitted into space will be equal to the amount of heat flowing from the base surface to the fin base.
