摘　　要：采用STAR-CCM+软件中的共轭传热模型对微通道换热器空气侧的流动及换热进行仿真,并利用试验结果对仿真结果进行验证,表明仿真模型的准确性可以满足工程设计要求。改变翅片开窗角度和开窗数进行仿真,结果表明,翅片开窗角度为45°且开窗数为14个时,微通道换热器空气侧换热量最大,压降相对较小。The flow and heat transfer of the air side for micro-channel heat exchanger is simulated using the conjugate heat transfer model of STAR-CCM+software. The simulation results are verified by the test results,which proves that the accuracy of the simulation models can meet the requirements of engineering design. The simulation is conducted by changing the fin louver angle and louver number. The results show that the heat transfer capacity of the air side for micro-channel heat exchanger is the largest and the pressure drop is smaller when the fin louver angle is 45° and the louver number is 14.
