In this paper,water was used as boiling medium,and the boiling heat transfer characteristics of smooth tube and three other kinds of enhanced tubes including integral pin-fin tube,porous surface tube and winded pin-fin tube were studied experimentally.
整体针翅管表面大量螺旋排列的三维翅片增大了换热面积、延缓了汽泡在壁面附近聚合形成大汽膜,使沸腾换热得到强化;多孔管采用机械方法在壁面加工出大量微细小孔,汽化核心数量和汽泡脱离频率均大幅提高,因此,沸腾换热强化效果显著;绕丝针翅管是一种复合强化手段,兼有整体针翅管和多孔管的优点,沸腾换热强化效果也较好。
补充资料：多孔层开管柱
分子式：
CAS号：
性质：在开管柱内壁上用适当的方法沉积上一层多孔性物质(如硅藻土、硅烷化硅胶、分子筛等)，即为多孔层开管柱。多孔性物质可做吸附剂用，也可做为载体再涂固定液使用。多孔性物质作为载体用的又称涂载体开管柱(support-coated open tubular column)。多孔层厚度约为0.1mm。与涂壁开管柱相比，它的内表面大，柱容量大，固定液流失减少，柱寿命增加。
