In some embodiments, the one or more metallic materials extend over at least a portion of an elastomeric material. In some embodiments, the materials include a tuned composite metallic foam including one or more metallic materials. A first portion of the foam has a first porosity and a second...
TIM热管理材料 2-1 热界面材料(Thermal Interface Material, TIM) 选择理想的热界面材料需要关注如下因素: 1)热导率:热界面材料的体热导率决定了它在界面间传递热量的能力,减少热界面材料本身的热阻; 2)热阻:理想情况下应尽可能低,以保持设备低于其工作温度; 3)导电性:通常是基于聚合物或聚合物填充的不导电材...
