摘要
对沿轴向截面突变的圆柱形钉肋的热力学性能做了综合理论分析，研究了其传热过程因传热和摩擦损失引起的不可逆熵产的变化特点，对３种肋结构做了比较。
The authors theoretically studied
the comprehensive thermal performance of the heat dissipation of a staggered pin fin array. The
distribution of the entropy generation due to heat transfer and fluid friction irreversibility
respectively in the heat transfer process is analyzed and a comparison is made for three profiles
of short pin fins, i. e., the uniform diameter pins and stepped diameter pins.
