摘　　要：对针刺型三维螺旋翅片管作理论分析和试验研究，得到了一定排列方式下的换热和风阻实验关联式，经与绕簧式、复合双金属轧制式、挤片式及套片式等冷却管进行热力性能比较，表明其不失为一种新颖高效的换热元件，应用于发电机空气冷却装置是可行的。Abstract After same theoretical analysis and experimenal study of pin type 3 dimensional spiral finned tubes, the correlation formula between heat transfer and flow resistance for a certain kind of arraying was obtained, which shows that, compared with the thermal performance of helical wound type, the dual metal rolled type, the pressed type and the slipped on lamina type of finned tubes, this is a new and highly efficient heat exchange element applicable for generator air coolers.
