摘　　要：介绍了一款大功率发射机的散热设计,由于存在局部热点,采用热管散热装置。设计全程使用了专业电子设备热仿真ICEPAK软件,进行计算机辅助设计,提高了设计效率。设计时根据发热量,计算给出了风机的选择方法。仿真发现即便选用高效率插片成型散热器仍不能消除局部热点,为此在关键热源底部预埋热管,进行温度均匀,这一措施能有效解决这一难题。经过设计验证,取得了很好的效果。A type of thermal design of high power transmitter is introduced,the heat pipe cooling device is used in consideration of the partial hot spot,.Thermal simulation professional software of ICEPAK is adopted for computer aided design throughout the design of the electronic equipment to improve design efficiency.According to the calorific capacity,air blower＇s choice method through the computation is given.The simulation shows that even if the selected high efficiency bonded fin heat sink can not eliminate the partial hot spot.For this reason the heat pipe is embedded in the essential heat source base in advance to make the temperature even.This measure can effectively solve this problem.And design verification has showed good results.
