| 摘 要： | 为了增强散热性能，常将环行肋与摩托车发动机汽缸整体锻造在一起。针对对流系数是常数和忽略辐射的情况，分别改变散热肋片的数目以及长度，计算了对外散热量的增加值。并且分别绘制出散热量与散热肋片数目和长度的关系曲线，对工程中散热肋片的选择有一定的实际意义。

| Abstract: | Usually,annular fins are integrally cast with the motorcycle engine cylinder to increase heat transfer to the surroundings.This paper calculates the increment of the heat dissipations of the heat transfer rate when we assume that the convection coefficient is constant and is negligible radiation,and draws the graphs which show the relations between the heat transfer rate and the numbers of the fins,and the relation between heat transfer rate and the length of the fin. It's significant practically to select the fins in engineering. |
