Thermal　contact　resistance　is　a　basic　problem　in　the　field　of　heat　transfer　problem.　This　article　puts　forward　and　describes　a　contact　thermal　resistance　test　method　between　annular　contact　interface　that　widely　exist　in　engineering　practice.　And　this　article　made　a　simulation　study　based　on　the　aluminium　column　joint　surface,　laid　the　foundation　in　annular　surface　contact　thermal　resistance　test　and　application　technology　research.
