Abstract : Thermal conductivity decides the rate of thermal energy absorbed and released of phase change materials (PCM).
Adding high conduction particles into the PCM matrix has been investigated for increasing the thermal conductivity. In general,
the effective thermal conductivity of composite PCM has anisotropic properties due to the orientation of additives. However,
effect of anisotropic PCM on thermal control properties is absence, which is studied in this paper by using an apparent heat
capacity method. An optimal match between anisotropic thermal conductivity and thermal conditions was further investigated.
It is found that anisotropic PCM was preferred for surface hot source, in this case, the additives should be oriented along a
special direction in PCM matrix when preparing composite PCM. While, isotropic material was desirable for point heat source,
and the additives should be homogeneously oriented in PCM matrix.
Key words- phase change material, anisotropic thermal conductivity, thermal conditions, heating area
