摘要:
随着地铁辅助变流器的开关频率不断提高,合理的热设计是保证辅助变流器正常工作的前提。针对地铁高频辅助变流器,对产品热设计进行研究。利用PLECS 软件计算关键模块的损耗,并设计多并联风道散热系统;采用Icepak 软件建立该散热系统仿真模型,仿真得到高频辅助变流器关键模块的温升;最后对高频辅助变流器样机进行温升试验。仿真结果与试验测试结果对比表明,温升吻合性较好,验证了仿真分析的有效性,且关键模块温升小于45 K,满足该系统的散热需求,并为高频辅助变流器热设计及优化提供了方法。
Abstract:
With the switching frequency of auxiliary converters continues to increase, reasonable thermal design is a prerequisite for ensuring the normal operation of auxiliary converters. The thermal design of products was studied according to the high-frequency auxiliary converter for metro vehicle. The power loss of key components was calculated by PLECS, and the cooling system which consisted of multi-duct was designed. The temperature rise of key components was analyzed by establishing the thermal simulation model of the system using Icepak; finally, temperature rise test of prototype was done. Through comparative analyses, the results of temperature rise simulation were in good agreement with test results, which verified the validity of the simulation analysis, and the temperature rise of the key modules was less than 45 K, which met the heat dissipation requirements of the system. The paper provided methods for the preliminary design and optimization of the high frequency auxiliary converter.
