In this paper the effect of porous metal plate-type-fin on the melting process of latent heat storage is studied fundamentally. Experiments using paraffin wax with the melting point of some 40℃ are conducted under the uniform heat flux condition for three kinds of heat storage systems (the system without any fins and the systems with vertical fin arrays and a single vertical fin). From the experiments, the melting pattern and the transient temperature change for each system are clarified. Further, natural convection flow in the system during the melting process is visualized using the photochromic technique. The visualization of the temperature field near the heat source wall is also tried using the shadowgraph technique.
