ShareSummary
Phase change materials (PCMs) have recently become more attractive in thermal management and energy storage applications as they possess the merits of high latent heat of fusion and high energy storage density. However, conventional PCMs are well-known for their defects of low thermal conductivity and volume variation during phase transition. In this work, the transient thermal performance of high-temperature sodium acetate trihydrate with aluminum foam heat sink is investigated. A mathematical model is developed and validated with experimental published data. The thermal performance of sodium acetate trihydrate-aluminum composite is compared to the conventional paraffin-copper foam composite under constant wall temperature and constant heat flux boundary conditions. The effect of metal foam integration and foam porosity, on thermal regulation time and maximum surface temperature, were investigated in the study. The results indicate that the inclusion of cellular metal foam with lower porosity offers a reduction in the surface temperature at the expenses of a shorter regulation time reflecting the enhancement of the effective thermal conductivity. Also, the salt hydrate-aluminum composite provides a better thermal management performance in terms of surface temperature and regulation time at this range of melting temperature compared to paraffin-copper composite. This work has the potential for the improvement of the efficiency of high-temperature phase change material-based heat sinks.
