| description | In order to improve the thermal conductivity of paraffin widely applied in phase change energy storage field, metal Na with high thermal conductivity, low melting point and low density was compounded to paraffin to form a new phase change energy storage material (Na/paraffin) in glove box, and the thermal conductivity, latent heat and heat storage/release characteristics of Na/paraffin were studied. The results show that thermal conductivity of 5%Na/95%paraffin composite phase change energy storage materials is improved 17.6 times compared to pure paraffin and the heat storage/release ratio of 5%Na/95%paraffin is two times of pure paraffin. After 200 cycles experiment, the phase transition temperature of 3%Na/97%paraffin composite phase change energy storage materials falls from 60.58℃to 59.65℃. The phase transformation latent heat and thermal conductivity rate are reduced from 166.7520J·g<sup>-1</sup> to 160.5632J·g<sup>-1</sup> and from 2.33W·m<sup>-1</sup>·K<sup>-1</sup> to 1.98W·m<sup>-1</sup>·K<sup>-1</sup>, respectively. |
