摘　　要：研制了一种新型三维内微肋管。在工质蒸汽进口压力为147、186、226和265kPa下,在凝结液质量流率为33～153kg/(m^2·s)范围内,通过对3种不同微肋尺寸的三维内微肋管的实验,得到了R11在水平管内的凝结换热性能。A new type of three dimenstional inner microfin tube is devoloped. Under four different pressures and in the range of condensing mass velocities from 33 to 153 kg/m2 . s,and by the experimental study of the three kinds of tubes with different microfin parameters, the performances of the condensation heat transfer for R11 in the horizontal microfin tubes and obtained. The experiments show that the inner microfin tube is a hopeful and nighty effective condensing heat transfer enhancement tube.
