摘　　要：首先对一种新型针刺型三维螺旋翅片管建立管外传热微分方程，得到该管外侧翅片的一些结构参数的优化值，并通过管外强迫对流换热试验，归纳出一定排列方式下的换热和流阻实验关联式。经与圆翅片管比较。Heat transfer differential equation of a new type of helical finned tube with spine three dimensional fin is solved for the optimum dimensions of the fin. Through the experiment, the empirical correlation of the forced convective heat transfer and pressure drop are obtained. Compared with the circular finned tube, this new type of finned tube is proved to be a high efficient heat exchange device.
