摘要
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。
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.
