摘　　要：本文以变压器油管内流动为研究对象,进行复合强化实验研究。分别对光管、内肋管和内肋管内插入扰流线在过渡区段进行了物理模化实验,获得了计算对流换热系数和流动阻力系数的准则方程,并对复合强化传热性能进行了讨论。This paper is about the combined enhancement heat transfer of transformer oil flowing in tubes. The physical molding experiment were performed on smoothing tubes, finned tubes and finned tubes with spiral inserts. The dimensionless eguation of friction facter and coefficient of convective heat transfer used for engineering calculation were given and the enhanced heat transfer characteristics were discussed in this paper.
