The　forced　convective　heat　transfer　of　mixed　molten　Hitec　salts　in　transversally　corrugated　tubes　with　different　sets　of　structural　parameters　were　obtained　through　experimental　study.　The　enhanced　heat　transfer　mechanism　in　transversally　tubes　with　different　sets　of　parameters　was　investigated;　the　deviations　between　the　fitting　correlations　under　corresponding　structural　parameters　and　experimental　data　were　within　10%.　In　addition,　based　on　the　consideration　of　transversally　corrugated　structural　factors,　a　general　correlation　applicable　to　three　sets　of　structural　parameters,　which　the　maximum　deviation　was　-11.8%,　was　proposed.　It　was　found　that　the　ratio　of　heat　transfer　enhancement　for　transversely　corrugated　tube　which　pitch　was　equal　9　was　1.6　by　comparison　with　the　experimental　points　in　smooth　tube.
