摘　　要：针对某机载液冷加固计算机在首飞安全性试验(SOF)中需要解决的关键问题,使用Fluent软件建立液冷加固计算机的分析模型并在低温环境条件下进行瞬态仿真分析。首先,预测在外部液冷系统关闭的环境条件下该液冷计算机的正常运行时间;然后,针对机箱液冷系统正常工作,低温环境条件下使用时的特定问题,提出了解决方案,确保了产品在SOF中的热性能可以满足可靠性要求。Aiming at the key problems to be solved in the SOF test of an airborne liquid-cooled reinforcement computer,the analysis model of the liquid-cooled reinforcement computer is established by using Fluent software and the transient simulation analysis is carried out under the condition of low temperature.Firstly,the normal running time of the liquid-cooled computer is predicted when the external liquid-cooled system is closed.Then,the solution is put forward according to the special problems under the low temperature environment when the liquid-cooled system works normally,which ensures that the thermal performance of the product in SOF can meet the reliability requirements.
