由于筒型永磁调速器在工作时因高速旋转会产生大量热量,而高温会导致永磁体退磁,减少导体转子与永磁转子间磁感线的切割,进而影响筒型永磁调速器的工作效率和工作性能,因此,需要设计一个风冷散热装置.基于筒型永磁调速器的结构及其工作原理,建立其热-流耦合模型,通过仿真分析,得到了筒型永磁调速器的温度场和流场仿真结果,流场速度迹线与实际工况相吻合;对比筒型永磁调速器各个部件的温度分布情况,相同工况下铜环的温度最高.与现场试验数据对比,得到铜环的温差约为0.5℃,验证了该风冷散热装置的合理性.
Thermal-Fluid Coupling Analysis of Heat Dissipation Structure of Air-Cooled Permanent Magnet Speed Governor
Due to the high-speed rotation of the tubular permanent magnet speed governor,a large amount of heat will be generated during operation,and the high temperature will lead to the demagnetization of the permanent magnet and reduce the cutting of the magnetic induction line between the conductor rotor and the permanent magnet rotor,thereby affecting the working efficiency and performance of the tubular permanent magnet speed governor.Therefore,it is necessary to design a new air-cooled heat dissipation device.Based on the structure and working principle of the tubular permanent magnet speed governor,a thermal-fluid coupling model is established.Through simulation analy-sis,the temperature field and fluid field simulation results of the tubular permanent magnet speed governor are ob-tained,and the flow field velocity trace is consistent with the actual working conditions.Compared with the tempera-ture distribution of each component of the tubular permanent magnet speed governor,the temperature of the copper ring is the highest under the same working conditions.By comparing with the field test data,the temperature differ-ence of the copper ring is about 0.5℃,which verifies the rationality of the air-cooled heat dissipation device.
