摘要
变流器采用"热管散热器+走行风冷"方式可简化柜体结构。为分析热管散热器的散热性能,利用Fluent软件分析了其流速和温度的分布特点,结果表明热管散热器在较低的车辆运行速度下仍具有较好的散热效果。实际的现场应用情况验证了仿真结果的准确性。
With heat-pipe radiator and air-cooling in driving state, structure of converter cabinet can be simplified. In order to analyze the thermal performance of heat-pipe radiator, velocity and temperature distribution are analyzed by Fluent software. Results show that heat-pipe radiator still has predominated performance at slowly driving velocity. The veracity of simulation results are verified by practical applications.
