摘要：

The　appropriate　heat　transfer　fluid　is　a　key　technological　issue　for　the　future　success　of　solar　thermal　technologies.　Molten　salt　as　the　heat　transfer　fluid　is　considered　to　be　one　of　the　most　promising　candidates　used　in　power　tower　plant　and　trough　power　plant　because　of　the　properties　of　high　working　temperature,　high　thermal　conductivity,　and　thermal　stability.　In　this　paper,　a　high　temperature　molten　salt　circular　system　was　built　to　study　the　heat　transfer　mechanisms　of　molten　salts.　We　first　choose　molten　LiNO3　circulations　in　a　horizontal　tube.　The　overall　heat　transfer　coefficients　of　our　molten　salt-oil　exchanger　under　difference　flow　rate　conditions　were　obtained,　heat　transfer　coefficients　for　the　salt-side　were　calculated　using　Wilson　plots,　variation　of　Nusselt　number　with　Reynolds　number　was　given　under　conditions　of　turbulent　flow.
