摘要

退火热解石墨(APG)是一种导热系数约为1500 W/(m·K)的材料。这种特性可以利用APG的热势来开发高导热复合材料，用于需要有效热管理的设备。本文采用钎焊方法将APG包埋在铝中，并测量了Al-APG复合基板的热性能。结果表明:Al-APG复合基板的导热系数约为620 W/(m·K)，是纯铝板(152 W/(m·K))的4倍;

Measurements of Aluminum-Annealed Pyrolytic Graphite Composite Baseplates with Improved Thermal Conductivity

Annealed pyrolytic graphite (APG) is a material with thermal conductivity of about 1500 W/(m·K). This property may enable the usage of APG’s thermal potential to develop highly thermally conductive composites for devices requiring effective thermal management. In this paper, APG has been encapsulated in aluminum by brazing, and the thermal properties of Al-APG composite baseplates were measured. The results show that the thermal conductivity of the Al-APG composite baseplates is about 620 W/(m·K), which is four times higher than the pure aluminum plate (152 W/(m·K)).
