摘要
对一种先进的强化换热元件──齿型螺旋翅片管束进行了传热及通风阻力特性试验研究,试验用直接法进行.得出受洁净气流冲刷时该管束传热特性关联式和通风阻力特性关联式,并将该种齿型螺旋翅片管束的性能与相同结构的整体型螺旋翅片管束进行了比较.
The experimental investigation of heat tranferr and flow asistance on an advanced heat exchange element-helically segmental finned tube bank is described in this paper. From the experimental investigation the correlative equations of heat transfer property and that of pressure drop are deduced. In addition, the comparisons between the helically segmented finned tube bank and the plain surface helically finned tube bank with the sameconstruction are introduced.
