【摘要】：采采用微氧化法制备Ga基室温液态金属热界面材料。实验结果表明,微量氧化镓的存在可显著改善液态金属的润湿性,且GaIn10合金热界面材料具有较高的热导率(约19.2 W·m~(-1)·K~(-1))。搭建接触传热测试平台,分别研究液态金属Ga及其二元、三元合金热界面材料的导热性能,对比市售导热硅脂,该新型镓基热界面材料,特别是其二元合金热界面材料,在大功率下工作时热源温度相对于导热硅脂下降近14℃,界面热阻只有5.4 Kmm~2/W,显示出更加优越的导热性能。
[Abstract]:Ga based liquid metal-thermal interface materials at room temperature were prepared by micro-oxidation method. The experimental results show that the wettability of liquid metal can be significantly improved by the presence of trace gallium oxide, and the thermal interfacial material of GaIn10 alloy has higher thermal conductivity (about 19.2W m-1 K-1). A contact heat transfer test platform was set up to study the thermal conductivity of liquid metal Ga and its binary and ternary alloys respectively. Compared with the commercial thermal conductive silicon grease, the new gallium based thermal interface material, especially its binary alloy thermal interface material, was constructed. At high power, the temperature of heat source decreases by nearly 14 鈩，
