Abstract:The new type of heat exchanger elements Ni based Implanted Spiral Finned Turbes (NISFT) was studied and tested, which can contribute to increase the efficiency and reliability. The relation of Nu, Eu and Re with different fin pitch, fin height, transverse pitch and longitudinal pitch were gained, which constituted the basic foundation for the engineering application of NISFT.
Keywords:enhanced heat transfer   heat exchanger   finned tube
