摘要
本文对某机载吊舱的散热进行了设计,分析了影响吊舱内部温度的因素,提出了一种新型的散热结构,针对密闭情况下吊舱内部温度情况,提高整机的散热能力,并使用热仿真软件ANSYS Icepak进行仿真分析,验证设计方案。结果表明,新型环控散热方案使得在恶劣环境温度为55℃时,吊舱内部负载芯片的稳态温度维持在83℃,满足设备工作温度的可靠性。
In this paper,the heat dissipation of an airborne pod is designed,the factors affecting the internal temperature of the pod are analyzed,and a new heat dissipation scheme is proposed to improve the heat dissipation capacity of the whole machine according to the internal conditions of the pod under airtight conditions.The thermal simulation software ANSYS Icepak is used for simulation analysis to verify the design scheme.The results show that the new environmental control cooling scheme maintains the steady-state temperature of the load chip inside the pod at 83℃at a harsh temperature of 55℃,which satisfies the reliability requirement of the equipment working temperature.
