摘　　要：对针翅管 (包括Sunrod焊接针翅管和整体针翅管 )进行了气相和液相传热性能实验研究 .试验分别在空气、水和油等介质中进行 ,得出了流体纵向流过针翅管的流动换热准则关系式 .The authors introduced a series of examinations on pin fin tubes. Tested mediums involved in gas (air), water, lube, diesel oil and diesel oil heavy oil mixture, heat transfer methods included single phase heat transfer and boiling heat transfer. The new information in this field was summarized, and the experiment data were compared with Q. Liao et al′s. The results showed that the pin fin tubes could intensify a few times more than smooth tubes no matter what in no change of phase or boiling heat transfer, and match better with Q. Liao et al′s experiment data.
