Heat transfer performance of a device integrating thermosyphon with form-stable phase change materials

Phase change materials (PCM) are applied worldwide as a thermal energy storage technology to reduce demands in buildings and solve environmental contamination issues. Form-stable phase (FSPCM), one branch of PCMs, can be improved by embedding them with thermosyphon, resulting better performance. In this paper, novel thermoplastic elastomer-based FSPCM was developed tested. A device integrating thermosyphon created, the heat transfer mechanism unit studied. The numerical model established, experiments were conducted accordingly. average relative error between experimental data predictions <3 %. Furthermore, parameter study investigate effects several essential factors. As result, evaporator length PCM conductivity found significantly influence unit's rate overall However, impact latent on negligible, for which it takes 1170 s, 1230 1394 s finish changing 136 kJ/kg, 160 200 respectively. This paper provides insights performance integrated form-stable discusses its relevance applications.
