摘　　要：针对电力电子变压器功率柜的散热系统提出了一种新的散热方案,将功率柜内部中空的承重框架设计成流体散热通道。借助Icepak分析软件,对功率柜在包含水冷条件下的通风散热过程进行了数值模拟。通过与不加水冷的数值模拟结果进行对照,结果显示添加水冷系统的发热模块的温度更低,且不需要改变功率柜内部原有结构的布局。所提出的散热方案对于提高电力电子变压器的性能和可靠性具有重要意义。In this paper,a new heat dissipation scheme is proposed for the heat dissipation system of a power electronic transformer power cabinet,in which the hollow load-bearing frame inside the power cabinet is designed as a fluid heat dissipation channel.Using Icepak analysis software,a numerical simulation is conducted on heat dissipation process of the power cabinet under water cooling conditions.By comparing the numerical simulation results with those without water cooling,the results show that the heating module with water cooling system has lower temperature and did not need to change the layout of internal original structure.Therefore,the heat dissipation scheme proposed in this paper is of great significance for improving the performance and reliability of power electronic transformers.
