Description

Technical Field

[0001] This utility model belongs to the field of building material technology, and specifically relates to a modular power generation and heat insulation wall building material. Background Technology

[0002] The existing structural designs of photovoltaic and thermal insulation panels for building exterior walls suffer from significant functional fragmentation and insufficient integration, mainly falling into two typical structural categories: One type is traditional thermal insulation wall panels, whose structure is mostly composed of a base board (such as a metal plate or cement board) and a single insulation layer (such as rock wool or polystyrene board). The base board is directly fixed to the main building frame with bolts, and the insulation layer is sandwiched between the base board and the wall. The core drawback of this structure is its limited functionality: it can only achieve thermal insulation and does not integrate power generation components, so it cannot use the solar energy received by the exterior wall facade to generate electricity, which is out of step with the development needs of modern building photovoltaics (BPV).

[0003] Another type is the traditional photovoltaic wall-mounted module, whose structure typically involves photovoltaic panels (such as crystalline silicon photovoltaic panels) fixed to the building's exterior wall via an independent support system (including horizontal purlins, vertical connectors, and adjusting fasteners). The support system must first be connected to the building's main structure (such as concrete walls or steel frames) using expansion bolts, and then the photovoltaic panels are fixed to the support system using clips or bolts, leaving only a 50-80mm installation gap between the photovoltaic panels and the wall. This structure has three major drawbacks:

[0004] The installation process is complex: the measurement and positioning of the bracket and the drilling and fixing require professional tools (such as laser level and electric drill) and multi-step verification (such as verticality and spacing adjustment). The assembly of photovoltaic panels and brackets requires precise alignment of the holes. The installation time of a single panel is 3-4 times that of traditional wall panels, and it also requires high skills from the construction personnel. Poor facade effect: The combined structure of photovoltaic panels and brackets is exposed, the panel gaps are uneven, and the metal parts of the brackets are prone to corrosion, which damages the integrity and aesthetics of the building facade; Insufficient heat dissipation: The back of the photovoltaic panel is in direct contact with the support frame, and the gap between the panel and the wall is blocked by the support frame, forming a closed space. Air cannot circulate effectively. Under strong sunlight, the operating temperature of the photovoltaic panel can reach above 55°C. The increased temperature leads to a decrease in power generation efficiency (the efficiency decreases by about 0.3%-0.5% for every 1°C increase).

[0005] Furthermore, neither of the above two types of structures achieves an integrated design of "insulation-power generation-installation convenience". When traditional insulation boards need to be installed with photovoltaic modules, secondary construction is required, which damages the original wall structure. Traditional photovoltaic modules, on the other hand, require an additional insulation layer to meet energy-saving requirements, resulting in increased construction costs and complicated procedures.

[0006] Therefore, the shortcomings of existing building exterior wall panels in terms of functional integration, construction efficiency, and heat dissipation performance urgently require a modular wall building panel that combines power generation, heat insulation, easy installation, and good heat dissipation. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this utility model is to provide a modular power generation and thermal insulation wall panel building material, which has a stable structure, is easy to install, and combines power generation, component heat dissipation, building insulation, and waterproofing functions, thus solving the problems of complex installation, insufficient heat dissipation, high cost, and poor thermal insulation performance of traditional photovoltaic modules.

[0008] The technical solution of this utility model is: a modular power-generating and heat-insulating wall building panel, including a support plate, an insulation layer and a power-generating glass plate.

[0009] The support plate has a rectangular structure with flanges at its edges. Steel angle brackets are installed on the flanges on both sides of the horizontal direction of the support plate for installation on the main building structure. Tongue and groove joints are installed on the flanges on both sides of the longitudinal direction of the support plate for interlocking between adjacent building panels. Ventilation holes are provided on the flanges on both sides of the longitudinal direction of the support plate.

[0010] The insulation layer is set on the surface of the support plate, located on one side of the flange surrounding the support plate.

[0011] The power-generating glass panel is fixed on the flange, and an air circulation interlayer is formed between the power-generating glass panel and the insulation layer.

[0012] Furthermore, the flange is provided with ventilation holes.

[0013] Furthermore, the support plate is a metal plate.

[0014] Furthermore, the thickness of the support plate is 0.3mm to 0.7mm.

[0015] Furthermore, the insulation layer is an aerogel felt.

[0016] Furthermore, the thickness of the insulation layer is 15mm to 25mm.

[0017] Furthermore, the power-generating glass panel is cadmium telluride photovoltaic glass.

[0018] Furthermore, the thickness of the power-generating glass plate is 6mm to 8mm.

[0019] Furthermore, the tongue and groove design includes a groove and a tenon that matches the groove structure. The groove is located on either side of the longitudinal direction of the support plate, and the tenon is located on the other side of the longitudinal direction of the support plate.

[0020] Furthermore, a sealing strip is also provided inside the groove.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention forms an air circulation interlayer between the power-generating glass panel and the insulation layer. An airflow channel can be formed within this interlayer, and ventilation holes are provided on the flange, allowing the airflow channels between the building panels to be interconnected. Utilizing the principle of rising hot airflow, the air in the airflow channels forms a natural flow, thereby carrying away heat from the surface of the power-generating glass panel, reducing the operating temperature of the photovoltaic module, and improving power generation efficiency. This invention also sets an insulation layer on the surface of the support plate, cutting off the heat conduction path formed by the support plate, preventing indoor heat loss due to heat conduction from the support plate, and enhancing the insulation performance of the building panels.
