摘要
利用红外热象仪对一叉流板翅式换热器内气流的温度分布进行了测试,获得了换热器模型内温度分布的特征,以及平均努谢尔特数和局部努谢尔特数变化规律的结果,并对换热器内的传热过程进行了分析.
The temperature distribution of a gas flow in a cross flow plate fin heat exchanger is measured with infrared image system.The characteristics of temperature distribution,mean Nuselt number and local Nuselt number are obtained.And by means of these results,the heat transfer process in the heat exchanger is analysed.
