设计了一系列的模拟模型研究周期l、相位差φ、振幅A、肋厚W这四个参数对波纹形微通道的影响
相位在 时通道换热效果最优
and the heat transfer area of the small period flow channel is large, which makes the excellent cooling effect; with the phase difference increased, the Nusselt number and the resistance coefficient is also increased, and the trend of increase becomes larger and larger, the heat transfer effect of the flow channel is best excellent when the phase difference between zero and half of pi;with the amplitude increased, the Nusselt number and the resistance coefficient is also increased, and the increase trend of resistance coefficient becomes smaller, which shows that it's beneficial to improve flow channel performance by high amplitude; with the fin thickness increased, the heat transfer performance becomes poorer
