摘要

对覆有亲水层的开缝翅片管换热器在析湿工况下空气侧换热和压降特性进行了实验研究，分析了入口空气相对湿度对空气侧特性的影响，以Nusselt数Nu和阻力系数f来反映空气侧换热和压降特性。实验结果表明，析湿工况下，Nusselt数随入口空气相对湿度的提高而增大，而阻力系数f变化不明显；换热器水侧中心温度越低，入口空气相对湿度对Nusselt数的影响越显著；干工况下，入口相对湿度对空气侧显热传热系数几乎没有影响。

Abstract

The airside heat transfer and pressure drop characteristics of slit fin-tube heat exchanger with hydrophilic coating were studied experimentally under dehumidifying conditions.The effects of inlet air relative humidity on airside performance were investigated.The Nusselt number and friction factor f were applied to describe airside heat transfer and pressure drop characteristics.The results show that Nu increases with the rise of inlet air relative humidity，while the change of friction factor f is not obvious.The effect of inlet air relative humidity on Nu becomes more remarkable with the decrease of waterside temperature.Inlet air relative humidity has little effect on sensible heat exchange of airside.
