摘要

基于数值仿真和试验研究方法，对用于轨道交通变流器的液冷散热器的性能进行了研究和优化设计，并将结果与HX,D,1C机车、HX,D,2B机车当前使用的散热器对比。结果表明，通过使用高效扰流技术和4组并联的流道结构，提升了散热器换热能力并降低了流阻，使散热器台面温升比HX,D,2B和HX,D,1C机车使用的散热器分别降低37%和14.1%，流阻分别降低36.9%和22.3%；通过使用对称的双面冷却结构，使IGBT安装面的均温性得到提升，并使其占用空间比单面平铺安装减少26%。

Abstract

Based on the numerical simulation and experimental research methods, the performance of the liquid cooled radiator used in the rail transit converter was studied and optimized, and the results were compared with the current radiator used in HX,D,1C and HX,D,2B locomotives. The results showed that the heat transfer capacity and the flow resistance of the radiator were improved by using the high-efficiency turbulence technology and four parallel channel structures, the temperature rise of the radiator table was 37%and 14.1% lower than that of HX,D,2B and HX,D,1C in use, and the flow resistance was 36.9% and 22.3% lower respectively. By using symmetrical double-sided cooling structure, the temperature homogeneity of IGBT installation surface was improved, and the occupied space was 26% less than that of single-sided tiling installation.
