摘要

针对传统热管散热器结构无法满足磁浮列车牵引变流器散热要求的现状，提出一种适用高热流密度的双面冷却热管散热器。通过应用数值仿真和试验测试的研究方法，将双面冷却热管散热器与体积相同的TM36型材散热器和CRH2高速动车组用热管散热器进行对比。结果表明，在相同风量和功率下，双面冷却热管散热器相对于体积相近的TM36型材散热器的散热效率提升32%，风阻降低35%，与CRH2高速动车组用热管散热器性能基本一致，但可节约成本和空间达50%以上。

Abstract

In view of the current situation that the traditional heat pipe radiator structure cannot meet the heat dissipation requirements of the maglev train traction converter, a double-sided cooling heat pipe radiator was proposed suitable for high heat flux density. The research methods of numerical simulation and experimental testing were used to compare the double-sided heat pipe radiator with the same volume TM36 profile radiator and CRH2 high-speed EMUs heat pipe radiator. The results showed that under the same air volume and power, the heat dissipation efficiency of double-sided heat pipe radiators with similar volumes of TM36 profile radiators was increased by 32% while the wind resistance was reduced by 35%, the heat dissipation performance of the heat pipe radiators for CRH2 high-speed EMUs was almost the same, but the cost and space could be saved by more than 50%.
