中文摘要：

相变材料的固液相变具有较高的相变潜热且相变体积变化小，在间歇性工作的电子器件的温控中得到广泛的应用。本文采用将铜泡沫嵌入相变材料中的方法来强化固液相变的传热性能的方法，提出一种封装有金属泡沫和相变材料的复合式散热器结构，实验研究了该散热器的加热表面的温度与时间的变化关系，分析铜泡沫孔隙率、孔密度以及石蜡物性等各个参数对该复合式热沉散热效果的影响。

英文摘要：

Phase change materials （PCM） have high latent heat of fusion with controllable temperature stability and have been used in thermal management for high power electronic device working in intermittent condition. Due to low thermal conductivity of PCM, high porosity open-cell metal foams can be embedded in the PCM to improve the thermal conductivity. In this paper, a hybrid heat sink with hollow substrate in which cooper metal foams filled with paraffin wax are sintered inside the hollow space is proposed. The temperature variations of heater surface are tested experimentally. The influence of metal foam porosity, pore diameter and PCM thermal property on total thermal resistance is experimentally studied.
