摘　　要：本文给出了一种既能提高换热效率 ,又能提高可靠性的新型换热元件—镍基渗层纵向翅片管 ,并对该新型强化传热元件进行了传热实验 ,得出了不同的翅片高度、横向节距、纵向节距下 Nu、Eu与Re的关系。A new type of heat exchange elements--Ni based implanted longitudinal finned tubes was studied and tested, which could contribute to increase the efficiency and reliability. The relations of the Nusselt number Nu, the Euler number Eu with different fin pitches, fin height, transverse pitches and longitudinal pitches , the Reynolds number Re were gained, which laid theoretical foundation for the engineering application of this new kind of finned tubes.
