Description

Technical Field

[0001] This utility model relates to the field of solar energy technology, and more specifically, to a solar photovoltaic wall panel. Background Technology

[0002] Solar photovoltaic (PV) wall panels are an advanced technology that combines photovoltaic power generation with building functionality, and are an important component of building-integrated photovoltaics (BIPV). At its core, it utilizes the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current (DC) electricity. The core component of a PV wall panel is the solar panel itself, primarily made of materials such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride. These panels serve both as the building envelope and as a power generation unit. In recent years, with the promotion of renewable energy, the application of PV wall panels in buildings has become increasingly widespread, such as in the form of PV curtain walls and PV sunshades. These panels not only improve the energy efficiency of buildings but also provide sun shading, heat insulation, and aesthetic enhancement.

[0003] For example, Chinese Patent Publication No. CN201721835051.1 discloses a solar photovoltaic wall panel, which includes an installation plate and a solar panel. One side of the installation plate has an installation groove adapted to the solar panel. A vertical plate is fixedly connected to one side of the solar panel. A rectangular frame is fixedly connected to the top and bottom of one side of the vertical plate. The side of the rectangular frame away from the vertical plate penetrates the installation plate and extends into its interior. The top and bottom of the side of the installation plate near the rectangular frame have fixing grooves adapted to the rectangular frame. A fixing plate is fixedly connected to the side of the rectangular frame extending into the installation plate. This solar photovoltaic wall panel can stably fix the solar panel to the installation plate, which is convenient and quick, preventing damage caused by the solar panel falling and affecting its performance. It saves a lot of time, reduces installation costs, and improves labor efficiency.

[0004] However, with the widespread application of solar photovoltaic technology, the efficiency and lifespan of photovoltaic modules have become critical issues in the aforementioned technical solutions. During the power generation process, some solar energy is converted into heat energy, causing the photovoltaic panel temperature to rise. Excessive temperature not only reduces photoelectric conversion efficiency but also accelerates material aging and shortens the module's lifespan. Traditional heat dissipation methods mainly rely on natural convection or forced air cooling, but in windless or lightly windy conditions, poor air circulation significantly reduces heat dissipation effectiveness, making it difficult to effectively control the photovoltaic panel temperature. Utility Model Content

[0005] The main objective of this invention is to provide a solar photovoltaic wall panel that effectively addresses the critical issues of photovoltaic module efficiency and lifespan arising from the widespread application of solar photovoltaic technology. During power generation, some solar energy is converted into heat, causing the photovoltaic panel temperature to rise. Excessive temperature not only reduces photoelectric conversion efficiency but also accelerates material aging and shortens module lifespan. Traditional heat dissipation methods primarily rely on natural convection or forced air cooling, but in windless or lightly windy conditions, poor air circulation significantly reduces heat dissipation, making it difficult to effectively control the photovoltaic panel temperature.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a solar photovoltaic wall panel, including a mounting frame, on which a solar panel is fixedly mounted, and first air pipes are fixedly mounted on both sides of the mounting frame. A second air pipe is mounted directly below the first air pipe. The opening height of the side of the first air pipe away from the second air pipe is higher than that of the solar panel. A first groove is provided between the solar panel and the first air pipe. A second groove is provided on the side of the first air pipe close to the first groove. A heat-conducting plate is provided in the first groove. A plurality of heat dissipation fins are fixedly mounted on the side of the heat-conducting plate away from the first groove.

[0007] Preferably, the second air tube is fixedly installed on the mounting frame, and the first groove and the second groove are in communication with each other.

[0008] Preferably, the heat-conducting plate is fixedly connected to the solar panel.

[0009] Preferably, one side of the heat-conducting plate passes through the second groove, and the heat dissipation fins are located in the inner cavity of the first air duct.

[0010] Preferably, the second trachea includes a second trachea body, and an air passage groove is provided on the side of the second trachea body near the first trachea.

[0011] Preferably, the air passage is connected to the first air pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) When the solar panel generates heat, the heat is directed to the heat dissipation fins through the heat conduction plate, and then the heat is dissipated to the inner cavity of the first air tube through the heat dissipation fins, so that hot air is generated in the inner cavity of the first air tube. Then, the hot air rises along the vertical inner cavity channel of the first air tube under the action of atmospheric buoyancy, so that negative pressure is generated at the bottom of the inner cavity of the first air tube, thereby forming a suction force, so that the air in the inner cavity of the second air tube passes through the air passage and enters the bottom of the inner cavity of the first air tube, and then the inner cavity of the second air tube generates a suction force, so that the external air enters the inner cavity of the second air tube through the openings at both ends of the second air tube body, forming a flue effect, accelerating the gas flow, carrying away the heat generated by the solar panel, and reducing the temperature. Thus, the solar panel can be effectively cooled even in windless or light wind conditions, improving the power generation efficiency and the life of the solar panel. Attached Figure Description

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 and Figure 2 As shown, a solar photovoltaic wall panel includes a mounting frame 1, on which a solar panel 2 is fixedly mounted. First air pipes 3 are fixedly mounted on both sides of the mounting frame 1, and a second air pipe 4 is positioned directly below the first air pipes 3. The opening height of the side of the first air pipe 3 furthest from the second air pipe 4 is higher than that of the solar panel 2. A first groove 5 is provided between the solar panel 2 and the first air pipes 3. A second groove 6 is provided on the side of the first air pipe 3 closest to the first groove 5. A heat-conducting plate 7 is disposed within the first groove 5, and several heat dissipation fins 8 are fixedly mounted on the side of the heat-conducting plate 7 furthest from it.

[0017] like Figure 3 As shown, in another embodiment of the present invention, the second trachea 4 includes a second trachea body 401, and an air passage groove 402 is provided on the side of the second trachea body 401 near the first trachea 3. When the heat dissipation fins 8 are cooled, external air enters the inner cavity of the second air pipe body 401 through the openings at both ends of the second air pipe body 401, and then the air is sent into the first air pipe 3 through the air passage 402, thereby cooling the heat dissipation fins 8 in the inner cavity of the first air pipe 3.

[0018] The working principle of this type of solar photovoltaic wall panel: In use, when the solar panel 2 generates heat, the heat is directed to the heat dissipation fins 8 through the heat conduction plate 7, and then the heat is dissipated into the inner cavity of the first air pipe 3 through the heat dissipation fins 8. This generates hot air in the inner cavity of the first air pipe 3. Then, the hot air rises along the vertical inner cavity channel of the first air pipe 3 under the action of atmospheric buoyancy, creating a negative pressure at the bottom of the inner cavity of the first air pipe 3. This creates a suction force, which causes the air in the inner cavity of the second air pipe 4 to pass through the air passage 402 and enter the bottom of the inner cavity of the first air pipe 3. This creates a suction force in the inner cavity of the second air pipe 4, which causes external air to enter the inner cavity of the second air pipe body 401 through the openings at both ends of the second air pipe body 401. This creates a flue effect, accelerates the gas flow, carries away the heat generated by the solar panel 2, and lowers the temperature. Thus, even in windless or light wind conditions, the solar panel 2 can be effectively cooled, improving power generation efficiency and the lifespan of the solar panel 2.

[0019] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
