【摘要】：对一款新型永磁磁力耦合器导风散热装置的进风孔进行仿真分析。首先,设计3种面积、开孔位置相同的进风孔,利用计算流体力学软件Fluent对模型的热场和流场进行流固耦合模拟,通过分析其最高温升及阻力矩选择合理有效的进风方案;其次,对选择出的进风方案进行倾斜开孔,分析不同倾斜角度对最高温升及阻力矩的影响关系,寻找较优倾斜角度;最后,进行不同的开孔个数模拟分析选择较优开孔个数。对比结果显示,合理开设倾斜进风孔可以有效降低永磁磁力耦合器整体最高温升和内部永磁体的最高温升,改变永磁体温度分布情况,降低外部转子的中心高温区温度,具有一定的实用价值。
[Abstract]:The air inlet hole of a new type of permanent magnet magnetic coupler is simulated and analyzed. First of all, three kinds of air intake holes with the same area and same opening position are designed. The fluid-solid coupling simulation of the heat field and the flow field of the model is carried out by using the computational fluid dynamics software fluent, and the reasonable and effective air intake scheme is selected by analyzing the maximum temperature rise and the resistance moment of the model. Secondly, the selected air intake scheme is tilted to open holes, and the influence of different tilting angles on the maximum temperature rise and resistance moment is analyzed to find a better tilting angle. Finally, the optimal number of holes is selected by simulating the number of holes. The results show that the maximum temperature rise of the permanent magnet magnetic coupler and the maximum temperature rise of the inner permanent magnet can be effectively reduced by the rational opening of the inclined air inlet hole, the temperature distribution of the permanent magnet can be changed, and the temperature in the center of the outer rotor can be reduced. It has certain practical value.
