In view of evaluation of capability of heat transfer enhancement, flow resistance and comprehensive performance through experiments, the result shows that the heat transfer enhancement of self-rotating twisted strip, twisted strip with oblique teeth, straight strip with elliptical teeth and steel spiral are 14 %，33 %，39.5 % and 16.5 % respectively within the Re range of 8 000~43 000; twisted strip with oblique teeth and straight strip with elliptical teeth are better as Re for less than 10 000; steel spiral and twisted strip come to the best of performance at the Re of 12 500; steel spiral and twisted strip are more reasonable in the abroard range of Re with more than 10 000.
