In this article, an analysis of impact of the form, size and location of pores on the effective thermal conductivity coefficient of porous metallic materials is presented. It is shown the influence of porosity parameters separately on the electronic and phonon; convective and radiation component of effective thermal conductivity. The distribution of the heat flow and temperature in the experimental samples were analyzed. Form and location of pores, which give opportunity to reached minimum electronic and phonon thermal conductivity, and also the most significant factor (porosity parameter), which influence on the electronic and phonon thermal conductivity are found. The previously expressed hypothesis about the impact on the convective motions by not only pores size, but also temperature is confirmed. Dependence of convective and radiation heat conductivity from the pores size in the porous metal material was obtained.
