Metal　Rubber　(MR),　characterized　by　its　porous　topology　and　metal-based　entangled　structure,　is　commonly　utilized　in　high-temperature　environments.　The　intricate　nature　of　MR＇s　structure　complicates　the　accurate　experimental　investigation　of　its　thermophysical　properties,　thereby　restricting　its　broader　applications.　Therefore,　based　on　numerical　simulation,　the　three-dimensional　reconstruction　of　the　spatial　topology　of　MR　is　achieved.　Additionally,　MATLAB-LS/DYNA-ABAQUS　is　coupled　to　replicate　the　heat　transfer　process　of　MR　at　macro-microscopic　scales.　Our　findings　elucidate　the　relationship　between　MR＇s　density,　number　of　contact　points,　and　thermal　conductivity,　revealing　a　stepwise　decrease　in　thermal　conductivity　along　the　forming　direction　and　a　spatially　varying　anisotropic　heat　transfer　mechanism　that　involves　energy　feedback　on　non-forming　surfaces.　Specifically,　at　the　material　level　of　investigation,　a　molecular　dynamics　model　for　heat　transfer　in　microscopic　metal　wire　contacts　was　generated.　This　model　enables　the　simulation　and　dynamic　tracking　of　atomic　group　thermal　behavior　under　temperature　effects.　Finally,　equivalent　thermal　conductivity　(ETC)　tests　were　conducted　concurrently.　By　integrating　the　thermoelectric　analogy　method,　we　introduced　for　the　first　time　a　hybrid　series-parallel　mode　and　the　tortuosity　of　discontinuous　materials.　This　approach　comprehensively　considers　critical　factors　such　as　porosity,　temperature,　and　interlayer　thermal　resistance,　culminating　in　the　development　of　a　predictive　numerical　model　for　thermal　conductivity　in　porous　metal-based　materials.　In　this　study,　a　bottom-up　multiscale　research　approach　is　proposed　to　deeply　explore　the　spatially　multidirectional　heat　transfer　mechanisms　of　microporous　metal-based　tangled　materials,　from　the　material　level　to　the　complex　topological　structural　level.　Simultaneously,　new　dimensions　are　opened　for　the　study　of　such　materials　with　unique　discontinuous　structural　characteristics.　©　2024　The　Authors
