摘要
采用数值计算的方法，对底面加热的微矩形通道组内充分发展区层流对流技热与导热的耦合换热进行了分析。得到了沿通道周边的局部努塞尔特数和总体平均努塞尔特数与固体基材的导热系数、液体的导热系数及微矩形通道的高宽比间的关系。
In this paper,the heat transfer by combined convection and conduction in micro-rectangular channel heat exchanger is analysed numerically,and the local Nusselt numbers along the channel's height and bottom and the overall average Nusselt number are obtained. Thetemperature distribution across the cross section of the channel and fin is presented.
