摘　　要：通风冷却技术是100%低地板轻轨车混合动力电源箱的核心关键技术之一。现基于模块化设计原则,进行了混合动力电源箱的结构设计,冷却方案采用强迫风冷方式。通过分析温升试验结果,并结合理论分析和仿真计算,针对原方案进行了优化改进。新方案通风散热能力更佳、防护等级更高,更具安全性和可靠性。Ventilation and cooling technology is one of the key technologies of 100% low-floor light rail vehicles hybrid power cabinet Based on the modular design principle, this article designed a hybrid power cabinet, the cooling solution of which was forced air cool ing. By analyzing the temperature rise test results, theoretical analysis and simulation, the original structure program was improved The ventilation and cooling capacity of the new structure program was hetter, with a higher degree of protection, more security and reliability.
