Latent heat storage devices use the melting enthalpy of a so-called phase change material (PCM) to store thermal energy. Open porous metals, such as 3D wire structures, allow the design of systems with tailored storage capacity and power. A geometric unit cell was identified, modelled and COMSOL Multiphysics® was used to investigate the transient behavior of the PCM melting front. By choosing the right wire materials and using soldered structures, the melting time can be significantly reduced.
