By　using　the　transversally　corrugated　tube,　heat　transfer　enhancement　with　molten　salt　was　studied　in　the　test　bench　of　molten　salt　convective　heat　transfer　in　our　laboratory.　The　total　heat　transfer　coefficents　of　molten　salt-oil　were　calculated　by　the　measured　data　of　flow　rates　and　temperatures.　Based　on　Wilson　plot,　the　convective　heat　transfer　coefficients　of　molten　salt　in　different　conditions　were　determined.　The　results　showed　that　the　average　total　heat　transfer　coefficients　of　molten　salt-oil　in　the　transversally　corrugated　tube　are　1.7　times　larger　than　that　in　smooth　pipe.　And　the　correlation　for　criterion　numbers　of　convective　heat　trabnsfer　of　molten　salt　in　transversally　corrugated　tube　was　Nu=0.022e(0.82)pr(1/3).　Good　agreement　can　be　found　between　the　excperimental　data　and　the　fitting　equation　with　deviation　of　6.2%.
