摘　　要：强迫式蒸发冷却系统具有介质用量小、发热体温度分布均匀、温差小的特点,具有良好的应用前景。本文详细阐述了强迫式蒸发冷却电机定子三维温度场的仿真方法,介绍了边界条件的合理简化方法。经试验验证,本文所用仿真方法具有较高的可靠性及准确度。在此基础上,本文研究了两种不同的结构参数对强迫式蒸发冷却电机定子温度场分布的影响。Forced evaporative cooling（FEC） system has significant advantages in less dosage of cooling medium, uniform thermal field and less temperature difference, which can be applied well in practice. This paper details the simulation method of 3D thermal field in stator with a FEC system, and proposes a simplified method in setting the boundary conditions. And the reliability and accuracy of the simulation method is verified by experimental method. On this basis, two structural factors that influenced the stator thermal field are analyzed by the simulation method.
