| 建立了多元微通道平行流冷凝器的稳态分布参数模型，与实验对比验证了模型的正确性。利用所建立的模型，研究了翅片高度、翅片间距、百叶窗开窗间距、百叶窗开窗角度变化对多元微通道平行流冷凝器传热和流动性能的影响。结果表明，随着翅片高度的增大，换热量逐渐增大，空气侧压降逐渐减小；随着翅片间距或者百叶窗开窗间距的增大，换热量和空气侧压降都是逐渐减小；随着百叶窗开窗角度的增大，换热量和空气侧压降都是逐渐增大。 |

| Abstract: |
| The theoretical model of the multiple micro-channel parallel flow condenser is established based on the method of distribution parameters, and validity of the model is verified by comparison with the experimental data. Based on this model, the effects of fin height, fin pitch, louver pitch and louver angle on the heat transfer and flow performance of multiple micro-channel parallel flow condenser are investigated. The results show that, as increasing of fin height, the heat transfer rate increases, but the air-side pressure drop decreases; when fin pitch increases, or louver pitch increases, the heat transfer rate and air-side pressure drop all decrease; as increasing of louver angle, the heat transfer rate and air-side pressure drop all increase. |
