摘　　要：H型鳍片管是一种新型高效强化传热管。对一定结构的H型鳍片管与螺旋翅片管换热器进行了比较性半工业试验研究,得到了H型鳍片管换热与阻力准则关系式,并与相同结构参数的螺旋翅片管进行比较。根据实验结果得出:H型鳍片管换热与阻力特性均优于同结构参数的螺旋翅片管。H-type finned tube is a new type,high-efficient enhanced heat transfer tube.Experiment study on a certain configurable H-type finned tube and helically finned tube bank is carried out.Formulas and curves for the characteristics of heat transfer and flow of H-type finned tube are obtained,compared with the helically finned tube of the same configurable parameters.from the result of the experiment we can conclude: the characters of H-type finned tube are better than helically finned tube of the same configura...
