摘　　要：基于石墨材料优异的各向异性导热性,本文针对物理模型为100 mm×100 mm×1.1 mm的石墨板、石墨-金属膜板、紫铜板进行热扩散能力的研究,并利用Fluent对"一角加一点热源"的仿真模型进行数值仿真。在同热流密度条件下,分析板材的物理特性、结构对热扩散能力的影响。Because of the excellent anisotropic thermal conductivity of the new graphite, it will be re-searched on the dissipation performance based on physical model for 100 mm × 100 mm × 1.1 mm graph-ite plate, the graphite - metal film plate, copper plate and various films. The FLUENT is used for nu-merical simulation about the ＂comer with a litter heat source＂ model. Analysis of the physical properties and structure of the plate is made on the influence of the material thermal diffusion ability in the same heat flow density condition.
