摘    要:本文对三维扩展表面管轴向槽的形状和深度对换热的影响,三维扩展表面管加多孔导液带组合的凝结换热进行了实验研究。结果表明轴向槽的形状和深度的影响均为10%左右。组合方法是强化水平低肋管凝结换热的有效方法,对乙醇,可提高凝结换热系数达152%,对于水蒸汽达185%。

关 键 词:扩展表面管  多孔导液带  凝结换热

Abstract:An experimental study was carried out for the condensation heat transfer on the three dimensional extended surface tube attached by a porous drainage strip. The results show that the combination of the three dimensional extended surface and the porous drainage strip is the effective method enhancing condensation heat tiansfer on the horizontal tube. The change of the shape arid depth of the axial grooves results in a 10% vaitation of condensation heal transfer coei ficienls. In the range of the experiments, for aocohol as the working fluid, the enhancement is up to 152%, and for water, 185% as compared with the horizontal low-finned tube.
Keywords:three-dimensional extended surface lube  porous drainage strip  condensation heat transfer  experimental study
