| 摘 要： | 运用热分析软件Icepak对望远镜LAMOST的圆顶围挡通道进行了热计算，提出了采用导热管冷却的方案，并着重对比分析了设置导热管后在围挡通道中通自然风和冷却风这两种不同状态下的温度场分布。通过数值计算与仿真显示了不同状态下的温度场的变化规律，这些数值分析结果显示了采用导热管的冷却效果明显好于风扇冷却的效果。这些大量的计算与分析为望远镜圆顶视宁度研究及LAMOST圆顶设计提供了理论依据与参考。

| Abstract: | The thermal distribution of the closed alleyway in telescope LAMOST dome was calculated and simulated by Icepak software. Then, a cooling scheme with heat-sink was brought forward. It emphasizes on comparing and analyzing the temperature field under two different conditions - one with normal temperature air and the other with cooling air .The numerical calculation and emulation demonstrate the discipline of the temperature distribution in the alleyway. According to these results, it displays the cooling project with heat-sink is much better than with fan. So the analysis of the cooling method is significant to enhance the seeing and develop the design of the dome. |
