摘要

With peak loads in the order of minutes and ergonomic considerations limiting surface temperatures and acoustical noise, handheld devices, such as smart phones or tablets, are excellent candidates for use of phase change materials (PCMs). The experimental and numerical evaluation of such materials used to enhance the performance of a forced convection cooled tablet is presented in this study. The PCM design parameters, including specific heat capacity, operating points (i.e., melt temperatures), thermal conductivity, and volume of phase change required for a specific time delay, are examined in the context of a tablet application.
