摘要:
通过数值模拟与试验研究相结合的方法,对某电力机车牵引变流器大功率模块水冷散热器的性能进行了研究。结果表明,不同的IGBT 元件模型对散热器的温升及热阻计算影响较大,发热模块模型计算出的散热器最大热阻值与试验值最为接近,相差约6%;散热器的热阻随冷却液流量的增加而减小,但与模块功率的变化无明显的关系;压降随冷却液流量的增加而增加。
Abstract:
The performance of water-cooled radiator for the high power module of an electric locomotive’s traction converter was studied based on numerical simulation and experimental study. The results show that the temperature rising and thermal resistance of radiators are obviously different when the models of IGBT are different. The highest thermal resistance of the radiator based on the model of heating module is about 6% higher than the maximum of experimental thermal resistance. The thermal resistance of the radiator decreases as the flow rate of cooling water increases and has no obvious correlation with the variation of the module’s power. The pressure drop of radiator increases as the flow rate of cooling water increases.
