摘要:
利用波动理论建立双向时滞模型，以研究圆孔结构和平板结构换热器微通道中温度波的振荡特性.结果表明，温度波的振幅随着无因次时间准数ωτ值的增大而减小；在流道中心，其振幅随着rhδα的增大均有一个先增大后减小的过程，并且平板结构换热器的性能要优于圆孔结构换热器；为了提高换热器的换热性能，圆孔结构一般设计1＜rhδα＜2，平行板结构一般设计1.5＜rhδα＜2.5.
Abstract:
 Using wave theory,a twoway delay model was established to research the temperature wave oscillation characteristic in the microchannel of circular and parallel plate heat exchanger.The results show that the amplitude of temperature wave will be reduced as the dimensionless time number   decreases. In the center of flow channel, with the increasing of the amplitude,temperature wave has a change process that increases firstly and then decreases, and the performance of parallel plate heat exchanger is superior to the circular heat exchanger; In order to improve heat transfer performance of heat exchanger, it was designed for the circular heat exchanger and   for the parallel plate heat exchanger.
