Abstract : The solution of the stationary problems of heat transfer is usually derived with the assumption that the heat conductivity coefficient is independent of the temperature. For relatively low temperature differences this assumption leads to small errors only; for large temperature differences (600-1000K), however, the error may be substantial. The paper presents a graphic-analytic method of the solution of the heat-transfer problem through surfaces ribbed by longitudinal, rectangular ribs, taking into account the variable coefficient of the heat conductivity of the material. An example is worked out demonstrating the feasibility of solving the heat transfer problem taking into account the temperature-dependence of the material heat conductivity. (Author)
