Research on heat dissipation technology of magnetron and its performance improvement method

随着大功率磁控管的广泛应用,人们对大功率磁控管散热性能也越来越重视,磁控管散热性能的好坏直接影响磁控管的寿命以及工作稳定性。本文针对风冷磁控管的工作特点,对威特公司现有磁控管技术进行优化,先从理论分析优化的方向,然后通过icepak进行模拟,得到可行的方案,制作样品进行实际的散热性能测试。最后我们发现,增加磁控管散热系统的散热表面积以及提升散热系统运行的雷诺数可以明显改善散热性能。

With the wide application of high-power magnetron, people are paying much attention to the heat-dissipation performance of high-power magnetron, because the heat-dissipation performance of magnetron directly affects the lifespan and stability of magnetron. Referring to the working characteristics of air-cooled magnetron, we optimize the existing magnetron technology in this paper. Firstly we decide the designing direction of analysis and optimization theoretically, and then simulate it by the software Icepak, and obtain a feasible plan. Samples are made to test the actual heat-dissipation performance. We find that increasing the superficial area of the heat-dissipation system of the magnetron and improving the Reynolds number of the heat-dissipation system could obviously improve the heat-dissipation performance.
