摘要

针对轨道交通领域日趋恶劣的热管理条件，文章对一种散热效率更高效的3D复合相变散热器进行了研究。应用数值仿真和试验测试的研究方法，将3D复合相变散热器与相同体积的双面热管散热器和水冷散热器进行对比，结果表明：与双面热管散热器相比，3D复合相变散热器在相同风速和功率工况下，热阻降低7.8%~10.5%，压降降低57.5%~63.6%，均温效果提升约52%；对于相同风机的冷却系统，单个IGBT最大许用功率可增大670 W，增幅约26.8%；额定工况的热性能与水冷散热接近。

Abstract

In view of the increasingly harsh thermal management conditions in the rail transit field, a 3D composite phase change radiator with more efficient heat dissipation capacity was studied. The research methods of numerical simulation and experimental testing were applied, and the 3D composite phase change radiator was compared with the double-sided heat pipe radiator of the same volume and the water-cooling system. The results showed that, compared with the double-sided heat pipe radiator, the 3D composite phase change radiator under the same wind speed and power conditions could reduce the thermal resistance by 7.8%~10.5%, the pressure drop by 57.5%~63.6%, and the temperature uniformity effect by about 52%; under the same fan cooling system, the maximum allowable power of a single IGBT could be increased by 670 W, an increase of about 26.8%; the thermal performance of the rated working condition was close to that of the water cooling system.
