　　[摘 要] 本文数值分析了翅片厚度对不同结构的翅片管换热器性能的影响。仿真结果表明：翅片管式

　　换热器管径、片宽、片距越大，翅片厚度对换热性能影响越大；开缝翅片与平片相比，翅片厚度对换热

　　性能影响较大；翅片厚度对不同排数换热器的换热性能基本无影响；翅片厚度对小管径和小管间距换热

　　器的性能影响较小。

　　[Abstract] The investigations of the impact of fin thickness on the heat transfer performance of fin-and-tube heat

　　exchangers with different structures are performed. The numerical simulation results show that, the heat transfer

　　performance of fin-and-tube heat exchanger with larger tube diameter, fin width and fin pitch is more sensitive to fin

　　thickness; the fin thickness of slit fin has larger impact on heat transfer performance than that of plain fin; the

　　impacts of fin thickness on heat transfer performance of the heat exchanger with different row numbers are

　　negligible; the impact of fin thickness on the performance of the heat exchanger with small longitudinal tube pitch

　　and small diameter tube is very small.
