　　[摘 要] 本文數值分析了翅片厚度對不同結構的翅片管換熱器性能的影響。仿真結果表明：翅片管式

　　換熱器管徑、片寬、片距越大，翅片厚度對換熱性能影響越大；開縫翅片與平片相比，翅片厚度對換熱

　　性能影響較大；翅片厚度對不同排數換熱器的換熱性能基本無影響；翅片厚度對小管徑和小管間距換熱

　　器的性能影響較小。

　　[關鍵詞] 翅片管換熱器；數值模擬；換熱性能；翅片厚度

　　[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.
