The　conjugate　heat　transfer　of　the　gas　and　solid　phase　in　the　nanoporous　media　with　various　three　dimensional　ordered　structures　was　numerically　solved.　The　obtained　results　for　the　effective　thermal　conductivity　are　in　good　agreement　with　the　experimental　data　when　the　density　of　the　porous　media　is　less　than　170　kg/m3.　Heat　transfer　coupling　model　considering　the　moisture　content　in　porous　material　was　established　as　well.　We　studied　the　effect　of　the　moisture　content　on　the　effective　thermal　conductivity　of　the　silica　aerogel,　and　the　results　show　that　the　effective　thermal　conductivity　gains　an　average　increase　in　2%　of　the　solid　thermal　conductivity　for　1%　increase　in　the　moisture　content　of　the　porous　material.
