In order to improve the heat transfer performance of phase change materials in latent heat storage systems, four different geometric proportions of rectangular fractal fin structures and a common rectangular fin structure were designed based on fractal theory. The distribution of water temperature field, solid and liquid phase and solidification time were obtained by simulating the solidification process of water in these structures, using sensible heat capacity method. The results show that comparatively high heat transfer was achieved in the cases with fractal fin compared to the common fin, which can easily reduce the solidification time by 54%. In addition, as the length ratio and width ratio increase, the heat transfer performance of the rectangular fractal fin structure will increase. The solidification time of phase change materials (PCM) in RL = 0.5 fin structure can be reduced by 34% compared with that of RL = 0.4 fin structure, and the fin structure of RW = 0.7 can be reduced by 25% compared with that of RW = 0.45.
