【摘要】：采采用微氧化法制備Ga基室溫液態(tài)金屬熱界面材料。實驗結(jié)果表明,微量氧化鎵的存在可顯著改善液態(tài)金屬的潤濕性,且GaIn10合金熱界面材料具有較高的熱導(dǎo)率(約19.2 W·m~(-1)·K~(-1))。搭建接觸傳熱測試平臺,分別研究液態(tài)金屬Ga及其二元、三元合金熱界面材料的導(dǎo)熱性能,對比市售導(dǎo)熱硅脂,該新型鎵基熱界面材料,特別是其二元合金熱界面材料,在大功率下工作時熱源溫度相對于導(dǎo)熱硅脂下降近14℃,界面熱阻只有5.4 Kmm~2/W,顯示出更加優(yōu)越的導(dǎo)熱性能。
[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，
