Abstract: The paper studies the heat-conducting properties of a porous material with an ordered structure, based on Schwartz P TPMS, taking into account the thermal conductivity of air in the interpore space. Thermal conductivity was studied for a TPMS material made of aluminum. The problem of thermal conductivity was solved by the finite element method in the Steady-State Thermal module of the ANSYS software package. The obtained results demonstrate that the thermal conductivity of the TPMS material with air is higher by 1.1% than the thermal conductivity of the lattice without air. The dependences obtained during the study will make it possible to predict the thermal conductivity of a TPMS material for applications in a variety of engineering problems.
