基于对传统的7 mm 管径翅片管换热器的CFD分析，本文提出了一种新的宽片与窄片组合的翅片管换热器，并对这二种翅片管换热器用 CFD 软件进行了数值模拟。数值研究结果表明：宽片与窄片组合的翅片管换热器比常规翅片管换热器的空气侧换热性能好，但是它的空气侧压降较低。整机实验结果表明：二者性能几乎相当。
基于對傳統的7 mm 管徑翅片管換熱器的CFD分析，本文提齣瞭一種新的寬片與窄片組閤的翅片管換熱器，併對這二種翅片管換熱器用 CFD 軟件進行瞭數值模擬。數值研究結果錶明：寬片與窄片組閤的翅片管換熱器比常規翅片管換熱器的空氣側換熱性能好，但是它的空氣側壓降較低。整機實驗結果錶明：二者性能幾乎相噹。

Based on the CFD analysis of the traditional fin-tube heat exchanger with 7 mm diameter tubes, a new fin-tube heat exchanger with combining wide and narrow fins was put forward. These two kinds of fin-tube heat exchangers were simulated with CFD software. The numerical simulation results showed that the air-side heat transfer performance of the fin-tube heat exchanger with combining wide and narrow fins was higher than that of traditional fin-tube heat exchanger, but the air-side pressure drop was lower. The experimental results showed that the performances of the new and traditional heat exchanger are almost the same.
