LIQUID METAL MATRIX THERMAL PASTE

摘要

A liquid metal matrix thermal paste comprises a dispersion of non-reacting thermally conductive particles in a low melting temperature liquid metal matrix. The particles preferably are silicon, molybdenum, tungsten or other materials which do not react with gallium at temperatures below approximately 100.degree.C. The preferred liquid metals are gallium and indium eutectic, gallium and tin eutectic and gallium, indium and tin ternary eutectic. The particles may be coated with a noble metal to minimize surface oxidation and enhance wettability of the particles. The liquid metal matrix thermal paste is used as a high thermally conducting paste in cooling high power dissipation components in conjunction with a conventional fluid cooling system.
