The article describes the transfer of thermal energy through porous bodies with closed and open porosity. The semi-empirical equation for finding the effective coefficient of thermal conductivity of bodies with a porous structure is derived. The equation of finding the thermal permeability of the porous material and the geometric characteristics of the porous structure are presented.
