摘　　要：采用有限元方法对模块化直流电源柜散热方式进行分析和设计。以标准尺寸的模块化直流电源柜为研究对象,在ICEPAK软件中分别建立其集中式散热和分布式散热的柜体仿真模型,通过仿真计算分别得到了两种散热方式下散热器的温度分布和模块前后的风压分布。对比了两种散热方式的优缺点,选择分布式散热作为模块化直流电源柜的散热方式。试验中测量了散热器的实际温升,其结果与仿真结果相符,验证了设计方法的正确性。Based on finite element method it analyzes and designs the heat-dissipating method about the modularized DC cabinet.Taking the standardized DC cabinet as example,the simulation models of the centralized heat-dissipating method and distributed heat-dissipating method are built separately in ICEPAK software.Temperature distribution of the heat sink and wind pressures of the module in two conditions are analyzed by simulation process.Comparing with these two heat-dissipating methods it shows their respective advantages and disadvantages,obtains the best heat-dissipating method.The experiments validates that the correctness of this analysis method just meets the analysis results.
