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。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.
