The phase-change material 6 is usually paraffin, and different types of paraffin have different phase-change temperatures, and can be selected according to the application scene of the phase-change energy storage box and the temperature requirement of a target point. The reinforcing particles 7 are usually metal powder, graphene and other nano particles, and since the paraffin wax has low thermal conductivity, the phase-change material of the pure paraffin wax is heated and melted slowly, and after the nano reinforcing particles are added, the thermal conductivity can be increased, so that the overall heat absorption and heat storage effects of the phase-change energy storage box are improved.

The thickness of the whole structure is controlled below 15mm, so that the heat source plate can be conveniently attached to the surface of a single heat source or a heat source plate. The flat construction not only saves space but also provides a larger contact surface for the heat source.
Fig. 4 is a partial cross-sectional view of the phase change energy storage box, which shows the distribution of internal rib columns from the top view, wherein the rib columns are perpendicular to the top and bottom plates and are basically distributed in an array in the horizontal direction throughout the whole internal cavity area.
Fig. 1 is an explosion diagram of the structure of the phase-change energy storage box. The bottom plate 1, the mounting feet 2 and the rib columns 3 are integrally formed, so that the flatness of the top and bottom surfaces can be ensured, thermal resistance caused by split welding can be avoided, and the heat transfer efficiency is higher.

Therefore, the selection of the size of the rib column needs to be comprehensively considered, and the mass ratio of the phase change material to the metal shell is generally controlled to be 1: about 2. Because the thermal conductivity of paraffin and other phase-change materials is low, the surface layer is often molten, the interior is still solid, the utilization rate of the phase-change material 6 is greatly reduced, and by adding metal powder, graphene and other nano particles, the reinforcing particles 7 and the phase-change material 6 are uniformly mixed, so that the heat absorption efficiency of the phase-change material 6 can be effectively improved.
