带侧向喷气孔的钉肋换热器的熵产分析

Entropy Generation Analysis on Pin Fin Heat Exchangers with Lateral Ejection Holes

对带侧向喷气孔的钉肋换热器冷却散热的热力学性能做综合理论分析，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 pin fin array in channels with lateral ejection holes in heat exchangers. 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 typical short pin fin channels. The results presented would be helpful for the design of the heat dissipation of pin fin heat exchangers.
