| 摘 要： | 针对所设计的多光束大气激光通信(MALC)系统，建立了激光光源温度场分析的仿真模型，运用热分析软件FLUENT对激光器(LD)的温度场进行了数值仿真，得到了温度场的分布曲线。结果表明，当气流速度大于5m／s时，风冷可以保证发射机终端的最高温度小于LD的安全工作最高温度，可作为MALC的有效散热方式。

| Abstract: | A simulation model of the temperatur field distribution of the laser diodes was presented for designing multeple-beam atmospheric laser communication(MALC) system.A numerical simulation,using the thermal analysis software FLUENT,was performed to gain the distribution of the temperature field of the LDs.The results show that wind cooling can keep the maximum temperature in the transmitter is lower than the maximum temperature for the LDs operating safely when the fluid velocity is no less than 5 m/s.Wing cooling can be selected as an effective cooling method for the MALC system. |
