• In using convective and radiative fins on heat exchangers, space radiators or nuclear fuel elements at high temperature, there are cases when the thick fins emit radiation and convection energy to the enclosing gas. In this paper, an analysis of a thick plate and annular fin is made. The two-dimensional temperature distribution and efficiency of the thick fins are solved by the digital computer. The numerical solution of the net-convective and net-radiative plate fin is presented. Lastly, the relation between the efficiency of the thick fin and that of the thin fin is discussed.
