液态金属作为 TIM2

我在网上搜索时看到一篇关于液体金属TIM 的博客文章。网址是 http://reviews.pimprig.com/cooling/coollaboratory_liquid_metal.php。

Indium Corporation has been the leader in Metal Thermal Interface Materials for many years, and the demand for materials tends to have its own life pattern. Many years ago there was a large demand for metals that were liquid at room temp such as Indalloy 51. This demand was mostly due to the search for a replacement for Mercury.

这篇博客文章指出了处理液态金属的复杂性。实际上,该材料的性能在所有测试过的 TIM 中排名第二。这就引出了另一个问题。金属热界面材料的粘合线厚度对于应用来说实际上可能太薄。我认为在这次实验中可能就出现了这种情况。金属热界面材料或液体金属的界面厚度可能在 0.001 至 0.002 英寸之间。如果盖子和散热器存在平面性问题,则可能会产生高达 0.004 英寸至 0.006 英寸的潜在空隙。这些空隙会大大增加接口的热阻,尤其是在使用比BLT 薄得多的金属热接口材料时。
