摘　　要：电子设备方舱热设计对机动式指挥通信系统的可靠性影响很大,而现行的方舱热设计方法存在缺陷,不能准确计算方舱所需的能耗。文中分析了现行热设计计算方法的不足,通过对方舱进行热学动态特性分析,推导出更为精确的计算公式,可提高电子设备方舱的热设计水平。The thermal design of the electronic equipment shelter has a great effect on the reliability of command and communication system. The traditional thermal design calculation method cannot calculate the energy needed by the shelter accurately. The deficiency of the existing thermal design calculation method is analyzed in this paper. The more accurate calculation formula is derived by the thermal dynamic characteristic analysis of the shelter, which can be used to improve the thermal design level of the electronic equipment shelter.
