Detailed implementation mode

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1 shown, a heat supply wall panel using solar energy for heat storage includes a frame 1 and a main board 2. The main board 2 is embedded in the frame 1. Pressing rings 3 for pressing both sides of the main board 2 are arranged on both sides of the frame 1 to realize stable connection and fixation between the main board 2 and the frame 1.

[0025] As Figure 2 shown, the main board 2 includes a base board 21, an insulation layer 22, a protective layer 23, a phase change material heat storage layer 24, a heat absorption layer 25, a breathable layer 26 and a decorative layer 27. Among them, the layers are bonded and fixed by a water-based adhesive or a water-based polyurethane adhesive.

[0026] The base board 21 is made of a light and high-strength building material, such as glass fiber reinforced plastic or polyurethane foam board, etc., as the base of the wall panel, and has good mechanical properties and durability. The insulation layer 22 is made of rock wool or polystyrene foam, etc., for reducing heat dissipation.

[0027] The protective layer 23 is made of a glass fiber cloth or a metal plate, etc., for protecting the internal structure of the wall panel and improving the durability of the wall panel. The phase change material heat storage layer 24 is made of hydrated salt, etc., and has a high heat storage density and good thermal stability, for storing the heat energy absorbed by the heat absorption layer 25. The phase change temperature of the phase change material used in this embodiment is 25 °C, which belongs to the category of solid inorganic phase change materials, and has a high heat storage density (250 KJ / KG), and is safe, flame-retardant and has no leakage risk.

[0028] The heat absorption layer 25 is made of silicon carbide or alumina, etc., and has excellent heat absorption performance, for absorbing sunlight and converting it into heat energy. The breathable layer 26 is made of a breathable film or a porous plate, etc., for ensuring the air permeability of the wall panel and preventing condensate from being generated inside the wall panel. The decorative layer 27 is made of a colored plastic film or wallpaper, etc., for beautifying the appearance of the wall panel.

[0029] During use, sunlight shines on the surface of the wall panel. The heat absorption layer 25 absorbs the sunlight and converts it into heat energy, and the phase change material heat storage layer 24 stores the heat energy. When the indoor temperature drops, the phase change material heat storage layer 24 releases heat, which is transmitted to the indoor through the heat insulation layer 22 to achieve heating and hot water supply. At the same time, the wall panel has excellent heat insulation performance, effectively reducing the energy consumption of the building.

[0030] During the actual use process, according to actual needs, the materials and structures of the wall panel can also be optimized and adjusted to meet the needs of different regions and different building types. For example, in cold regions, the thickness of the heat insulation layer 22 can be appropriately increased to improve the heat insulation performance of the wall panel; in hot regions, the air permeability of the air permeable layer 26 can be appropriately increased to improve the heat dissipation performance of the wall panel.

[0031] As Figure 3 shown, the frame 1 includes a U-shaped bottom frame 11 and a strip-shaped top frame 12. Locking members 4 are provided between both ends of the bottom frame 11 and both ends of the top frame 12.

[0032] As Figure 3 shown, the locking member 4 includes a plug rod 41, a socket tube 42 and a hook 43. The plug rod 41 is arranged at both ends of the bottom frame 11, the socket tube 42 is vertically arranged at both ends of the top frame 12 and is for the plug rod 41 to be inserted. The hook 43 is arranged on the outer wall of the plug rod 41, and a locking hole 44 for the hook 43 to be embedded is arranged on the socket tube 42.

[0033] When installing the frame 1, insert the main board 2 into the bottom frame 11, then buckle the top frame 12 on the main board 2, and control the bottom frame 11 and the top frame 12 to approach each other, so that the plug rod 41 is inserted into the socket tube 42, and the hook 43 is snapped and embedded into the locking hole 44, realizing the quick assembly of the frame 1 and making the assembly process easier and more convenient.

[0034] As Figure 3 、 Figure 4 shown, both the bottom frame 11 and the top frame 12 include a pair of edge plates 13 and a middle plate 14. Clamping strips 15 are arranged on both sides of the middle plate 14, and clamping grooves 16 for the clamping strips 15 to be embedded are arranged on the edge plates 13. Therefore, by setting the replaceable and easily assembled middle plate 14 with adjustable thickness, the thickness adjustment of the entire bottom frame 11 and top frame 12 is realized to clamp the main board 2 with different thickness requirements, improving the practicability of the entire wall panel.

[0035] As Figure 3 、 Figure 4As shown in the figure, dovetail blocks 17 are provided on both sides of the upper end surface of the top frame 12, and grooves 18 for the dovetail blocks 17 to be embedded and dovetail grooves 19 connecting the grooves 18 and allowing the dovetail blocks 17 to slide and be embedded are provided on both sides of the lower end surface of the bottom frame 11. Therefore, the quick installation and stable fixation between the upper and lower wall panels are realized by setting the sliding installation method, which is convenient for on-site construction and improves the construction efficiency.
