摘　　要：基于某复平面上包含原点的任何简单闭曲线外区域,总可以共形映照为另一复平面中单位圆外区域的事实,用复变方法给出了一类凸形截面管道对流换热能力的粗略估计算法,且该算法可以用来对其他类型截面的管道对流换热能力进行预估.Based on the fact that there is always a quasicoformal mapping of unit circle external area in another complex plane for the external area in any simple closed curve including base point in a certain complex plane, this paper applies complex variable methods directly to obtain a rough estimation on convective heat transfer of one type of convex pipes. This result is suitable to the approximate analysis of convective heat transfer about the pipes.
