摘　　要：根据新一代天气雷达设备的工作环境和运行状态,阐述了雷达系统热设计的工作原理和结构特征,主要对雷达系统发射机的热通道和散热系数进行科学评估,汇总2008～2010年河南省5部新一代天气雷达的热报警数据,通过对运行环境中热报警信息的统计和分析,认为机房布局、制冷设备、冷热通道、数据监控、制冷材料等项目需要改进和调整,提出将供电、制冷、监控和管理组件整合成全面、一体化的解决方案,同时提出下一代热设计与分析技术的重点和发展方向。This paper introduces the work principle and structural characteristics of the thermal design system according to work environment and operation mode of the new generation weather radar system with emphasis on the evaluation of the hot channel and heat release coefficient about the transmitter. Descriptive statistic and analysis were carried out on the alarm datum of radar system in period of 2008-2010. The authors hold that computer room layout, refrigeration equipment, cool and hot passageway, data monitoring, refrigeration materials and some solutions need improvement and adjustment to realize the integration of the power supply, refrigeration, monitoring and manage. Major points and development trends of the next generation thermal design and analysis technique of the radar are also pointed out.
