风冷永磁调速器散热结构热-流耦合分析
Thermal-Fluid Coupling Analysis of Heat Dissipation Structure of Air-Cooled Permanent Magnet Speed Governor
摘要
Abstract
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.关键词
