The Experimental Exploration of Embedding Phase Change Materials With Graphite Nanofibers for the Thermal Management of Electronics

摘要

To improve the thermal performance of phase change materials (PCMs), graphite nanofibers were embedded into a paraffin PCM. The thermal effects of graphite fiber loading levels (0-5 wt %) and graphite fiber type (herringbone, ribbon, or platelet) during the melting process were examined for a 131 cm~3 volume system with power loads between 3 W and 7 W (1160-2710 W/m~2). It was found that the maximum system temperature decreased as graphite fiber loading levels increased and that the results were fiber-structure dependent.
