Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic and photothermal systems, specifically to a solar flat plate collector with power generation function. Background Technology

[0002] Existing flat-plate solar collectors consist of a solar panel and a heat exchange tube assembly at the bottom, which are then assembled using a frame. They primarily function to collect solar heat, utilizing the photothermal conversion of solar energy for reuse. However, the heat exchange tube assemblies at the bottom of existing solar panels are perforated components. During actual heat transfer, some heat is lost through the gaps in these perforated components, resulting in low thermal efficiency. Furthermore, with the development of photovoltaic technology, how to efficiently integrate power generation into flat-plate solar collectors has become a pressing technical problem that needs to be solved in the photovoltaic and solar thermal fields. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a solar flat-plate collector with power generation function, which reliably assembles photovoltaic solar panels to generate electricity and improves the utilization efficiency of thermal energy and solar energy.

[0004] A solar flat-plate collector with power generation function is characterized in that it comprises:

[0005] A border component, wherein the border components are assembled to form a quadrilateral structure;

[0006] Amorphous silicon photovoltaic panel modules;

[0007] The heat collection plate assembly includes an upper heat absorption layer and a lower heat exchange tube assembly;

[0008] And the insulation layer;

[0009] The frame assembly has a thickness. An amorphous silicon photovoltaic panel assembly, arranged in a rectangular pattern, is embedded in the upper part of the frame area of ​​the quadrilateral structure along its height direction. A photovoltaic junction box is correspondingly provided at the electrical output end of the amorphous silicon photovoltaic panel assembly. The photovoltaic junction box is located at the exposed end of the entire solar flat-plate collector. A heat collection plate assembly and an insulation layer are sequentially arranged from top to bottom in the lower layer of the frame area of ​​the quadrilateral structure. The middle layer of the frame area of ​​the quadrilateral structure is a hollow layer. The amorphous silicon photovoltaic panel assembly is tightly fitted to the position corresponding to the frame. The insulation layer is encapsulated on the lower surface of the heat collection plate assembly, and the outer periphery of the insulation layer is tightly connected to the corresponding position of the frame.

[0010] Its further features are:

[0011] The amorphous silicon photovoltaic panel module is specifically a perovskite photovoltaic panel module or a cadmium telluride photovoltaic panel module;

[0012] The amorphous silicon photovoltaic panel module is composed of photovoltaic high-transparency glass, perovskite printed layer or cadmium telluride printed layer, high-transparency EVA film, and photovoltaic glass stacked from top to bottom.

[0013] The frame is provided with a positioning and mounting groove at the position of the amorphous silicon photovoltaic panel module in the height direction. The top of the positioning and mounting groove is provided with an upper stop edge, the outer side of the positioning and mounting groove is a side stop edge, and the bottom of the positioning and mounting groove is a support edge.

[0014] The frame components are assembled to form a quadrilateral structure, which includes a pair of long sides and a pair of short sides. The amorphous silicon photovoltaic panel assembly is formed by combining several amorphous silicon photovoltaic panels of unit shape. The length of each group of amorphous silicon photovoltaic panels is the corresponding length of the short side of the quadrilateral structure. Several groups of amorphous silicon photovoltaic panels are arranged sequentially along the long side direction and embedded in the corresponding positioning and mounting slots to form a reliable assembly.

[0015] The rectangular arrangement of amorphous silicon photovoltaic panels formed by splicing is sealed with silicone sealant in the area corresponding to the positioning and mounting groove to ensure that the absorbed heat energy is not easily lost.

[0016] The inner side of the frame is provided with a side protrusion stop edge corresponding to the position of the upper surface of the heat collection plate assembly. The side protrusion stop edge is pressed into the corresponding boundary position of the upper heat absorption layer, which ensures that the heat collection plate assembly will not fall off or be pressed onto the amorphous silicon photovoltaic panel module when the equipment shakes or changes angle.

[0017] The lower heat exchange tube assembly is a combination structure with S-shaped and U-shaped heat exchange tube cavities built into the heat-conducting plate. It includes a medium inlet and a medium outlet. The heat-conducting plate is made of a high thermal conductivity material to ensure that heat energy is reliably absorbed and transferred by the medium.

[0018] Alternatively, the lower heat exchange tube assembly is a composite structure formed by heat exchange tube assembly and upper and lower cover plates, which includes a medium inlet and a medium outlet. The upper and lower cover plates are made of high thermal conductivity material to ensure that heat energy is reliably absorbed and transferred by the medium.

[0019] The medium inlet and medium outlet are fitted with external connectors, which pass through the corresponding frame or the bottom insulation layer and are used to connect to external pipelines.

[0020] The photovoltaic junction box is located on the side of the short side or the side of the long side of the quadrilateral structure formed by the frame components.

[0021] By adopting this utility model, the amorphous silicon photovoltaic panel module of the flat plate solar collector with power generation function outputs the converted electrical energy through the photovoltaic junction box. The amorphous silicon photovoltaic panel module is tightly attached to the frame, and the insulation layer is encapsulated on the lower surface of the heat collection plate assembly. The outer periphery of the insulation layer is tightly connected to the corresponding position of the frame, so that the heat energy obtained by the amorphous silicon photovoltaic panel module is basically transferred to the medium of the lower heat exchange tube assembly after being absorbed by the upper heat absorption layer through the hollow layer. Its overall solar energy efficiency is greatly improved, reaching up to 92% or more. In summary, it reliably assembles photovoltaic solar panels for power generation and improves the utilization efficiency of thermal energy and solar energy. Attached Figure Description
