摘　　要：针对巨型水电机组励磁整流柜散热问题,介绍了利用环形热管散热的工作原理和自冷型环形热管整流柜的研制改进过程,分析了一体式环形热管散热器和水平对称结构的优势及其在乌东德水电站的应用。结果表明,采用完全自冷方式的环形热管励磁整流柜可在现场长期稳定运行,从设计原理上解决了灰尘、噪声、工作电源、维护等一系列问题,提高了设备的安全可靠性和自动化水平,同时降低了能耗,节能环保效益显著。In order to solve the heat dissipation problem of heat pipe rectifier cabinet for excitation system of giant hydropower station, the working principle of loop heat pipe and the processes of development and improvement of loop heat pipe rectifier cabinet were introduced. The advantages of integrated loop heat pipe and horizontal symmetry structure, as well as its application in Wudongde Hydropower Station were analyzed. The practice shows the loop heat pipe rectifier cabinet adopting completely self-cooling heat dissipation mode is in a thermal stable state after long-term operation in the field, and a series of problems, such as dust, noise, power supply, maintenance, can be solved from the design principle. Meanwhile, it can improve the safety, reliability and automation level of the equipment and reduce the energy consumption, the benefits of energy-saving and environmental protection are obvious.
