摘　　要：通过对加固显示器内部散热环境的分析,基于界面材料改善、低热阻散热通道设计、壳体结构散热翅片参数优化三种方式,提出了一种高亮度加固显示器背光组件散热优化方法,并以某型加固显示器为研究对象,对该型加固显示器背光组件原有的设计方案和优化方案的散热性能进行了对比验证。结果表明,提出的散热优化方法可以有效地降低背光组件上LED的工作温度,显著提高背光组件的热可靠性。A heat dissipation optimization method was proposed for the backlight module of the high-brightness rugged display by improving interface materials,designing low thermal resistance heat dissipation path and optimizing parameters of the cooling grid,through the analysis of the internal heat dissipation environment of the rugged display.A certain type of ruggedized display was taken as the research object,and the heat dissipation performance between the original design and optimized design was compared.The results showed that the working temperature of the LED on the backlight module was greatly reduced after applying the proposed heat dissipation method.
