摘要
本文介绍了某地面通信设备结构散热设计过程,在满足总体单位提出的结构尺寸需求下,通过对元器件发热量以及热量传播方式的分析,设计出传导配合自然对流散热机箱以及强迫风冷机箱两种方案,并采用ANSYSIcepak软件进行温度仿真验证,通过合理设置环境条件和求解参数,计算出温度仿真云图,得到关键元器件工作温度,结果表明两种机箱方案均满足散热需求。
This paper describes the heat dissipation design process for the ground communication equipment. In order to meet the structural size requirements proposed by the general unit,two kinds of conduction schemes combined with the natural convection radiator box and the forced fan box were designed by analyzing the heating and heat transfer modes of the components. Temperature simulation was performed using ANSYS Icepak software. By reasonably setting the environmental conditions and solving the parameters,the temperature simulation cloud is calculated,and the working temperature of key components is obtained. The results show that the two cabinet schemes can meet the heat dissipation requirements.
