Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panels, and in particular relates to a photovoltaic and thermal integrated building roof structure. Background Art

[0002] In the integrated design of photovoltaic buildings, photovoltaic panel components are generally used to replace the outermost panels on the roof or wall, that is, photovoltaic panel components are combined with the roof and exterior wall components. This can not only meet the various performance requirements of the exterior wall, but also utilize solar thermal energy for power generation, which has the advantages of generating green energy without occupying land.

[0003] However, due to the insufficient strength of photovoltaic panel components, they cannot meet the impact resistance and wind resistance requirements of roofs and walls, and there is heat transfer phenomenon in the utilization of solar thermal energy, and they do not have thermal insulation effect. Therefore, photovoltaic panel components cannot directly replace concrete and other building materials as the roof structure of the house, resulting in the disadvantage of high manufacturing cost of photovoltaic building integration.

[0004] Although conventional technical means such as adding foam boards, rock boards, etc. to photovoltaic panel components have low costs, they still cannot solve the above problems due to the defects of the boards being soft, easy to deform, and not fireproof.

[0005] The present invention designs a photovoltaic and thermal integrated building roof structure to solve the above problems. Summary of the invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A photovoltaic and thermal integrated building roof structure, which includes an outer frame, battery cells, a thermally conductive film, a thermal insulation plate, and a heat exchange tube. The battery cells, the thermally conductive film, the thermal insulation plate, and the heat exchange tube are all located in the outer frame. The thermally conductive film covers the lower end of the battery cells, the thermal insulation plate is located below the thermally conductive film, the heat exchange tube is embedded in the upper end of the thermal insulation plate, the thermally conductive film is closely attached to the upper surfaces of the thermal insulation plate and the heat exchange tube, and the inner and outer surfaces of the thermal insulation plate are coated with aerogel.

[0007] As a preferred solution, the inner cavity of the insulation board is composed of several closely arranged cavities, the cavity is a regular hexagon, and has openings at the upper and lower ends of the cavity. High-strength plates are provided at the upper and lower ends of the insulation board, and the two high-strength plates respectively cover the two openings of the cavity.

[0008] As a preferred solution, the insulation board material is a composite paper core and surface paper mixed with aerogel.

[0009] As a preferred solution, a glass cover plate located above the battery cell is installed in the outer frame.

[0010] As a preferred solution, the outer frame is composed of an aluminum frame and a bottom frame, the battery cells, thermal conductive film, and insulation board are installed inside the bottom frame, and the aluminum frame is installed on the top of the bottom frame.

[0011] Compared with the prior art, the advantages of the present invention are: 1. The present invention adds an insulation board made of aerogel composite to the interior of the photovoltaic panel structure, and cooperates with a thermal conductive film to more effectively absorb solar thermal energy, provide heat dissipation function for the battery cell, and improve the photoelectric conversion efficiency. The insulation board is not easy to deform at high temperatures, and has flame retardant, thermal insulation and heat insulation effects. In combination with a heat exchange tube, the heat collected by the insulation board is transported to an external heat recovery system, which makes more efficient use of solar thermal energy and improves the thermal rate of the entire photovoltaic panel component. In addition, the insulation board structure can also improve the compression and impact resistance of the entire component.

[0012] 2. The high-strength plate of the present invention forms a closed cavity in the cavity inside the insulation board, so that the insulation board has good thermal insulation function, and the heat transferred to the inner cavity of the insulation board undergoes physical processes such as refraction and attenuation to reduce heat propagation, thereby achieving the effect of thermal insulation. In addition, the insulation board shape composed of the cavity and the high-strength plate has higher pressure resistance and impact resistance.

[0013] 3. The insulation board material of the present invention is a paper core and a surface paper composited with aerogel, so that the insulation board has good toughness, resilience, flame retardancy, and thermal insulation properties. Combined with the inner cavity structure, the buffering performance of the insulation board is improved, and it has a higher energy absorption value per unit volume.
