摘　　要：通信行波管放大器一般工作于室外环境,工作环境恶劣,要求具有较高的可靠性。散热系统的性能对放大器性能及可靠性有决定性的影响。本文对通信行波管功率放大器进行了热分析设计,通过对不同翅片密度的散热器模型进行仿真分析,得到了最佳的翅片密度分布方案,并对散热器及机箱内部进行了优化设计,保证了放大器的散热系统满足设计要求。Communication traveling-wave tube(TWT)amplifiers usually work in outdoor,where the working environment is harsh and it requires the amplifiers having higher reliability.The characteristic of cooling system has decisive influence on the performance and reliability of communication TWT amplifiers,therefore thermal analysis and design of the amplifiers are carried out.With the simulation analysis of radiator models with different fin densities,the optimal fin density distribution scheme is obtained.The radiator and the interior of the chassis are optimized to ensure the heat dissipation system meeting the design requirements.
