| 摘 要： | 研究了195t／h开架式海水气化器翅片管的换热过程。利用ANSYS软件建立了挤压式翅片管模型并求解内外表面温度，针对翅片管的结构及温度载荷特点，采用一维管流理论，分析计算了翅片管内外传热过程，给出了其传热系数随管内LNG流速、管外海水温度等变化的特性曲线。结果表明，LNG的流速及海水温度对翅片管的传热过程有显著影响。

| Abstract: | The heat exchange progress for rib-tube of open rack vaporizer （ORV） was studied. Using ANSYS software, the modal of extruded rib-tube was built and its in-and-out temperature was solved. According to its structure and temperature distribution, the heat character of the rib- tube is obtained with the one-dimensional pipe flow theory. The results show that the parameters of LNG velocity, sea temperature and so on have important influence on the heat exchange progress. |
