Thermal Interface Material (TIM) TIM 是英飞凌新热界面材料的缩写。 随着电力电子器件功率密度与日俱増,功率模块与散热器之间的导热界面设计对于工程师来说是个严峻的挑战。TIM 是专为英飞凌功率模块而开发的预处理导热界面材料,性能优于当前市场上的通用材料。TIM 不仅提供最低的热阻,还满足最高质量标准,使功率...
元器件在工作时都会有热量产生,所以需要添加辅助散热。 TIM,thermal interface material,最常见的就是硅脂、导热凝胶、石墨散热贴,等等。 如果是金属后壳,它也会承担一部分散热效用。 屏蔽罩、中框、后盖、摄像头等位置均可以贴上铜箔或石墨膜来帮助散热。 现在,随着发热量的增大,手机厂商也开始加入热管了。 图片来...

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料; ...
Thermal Interface Material with Aligned CNT and Its Application in HB-LED Packaging K. ZHANG1, Matthew M.F. YUEN1, N. WANG2..
A thermal interface material in the form of a resilient thermal conductor sheet (e.g., a felt consisting of conducting fibers clung together without a binder, and a resilient polymer-matrix composite containing a thermally conducting filler) usually cannot be as thin or conformable as one in ...
Phase change material solutions reduce thermal interface resistance and improve the heat transfer between surfaces by expanding after exceeding a pre-determined temperature. Polyimide, silicone and aluminium films are available with phase-change coating. ...
