Claims

1. A photovoltaic curtain wall assembly, characterized by, The photovoltaic curtain wall assembly, from the direction of sunlight incidence, includes a front glass (1), an encapsulating film layer (4), a decorative film layer (5), a back glass (6), and a heat-conducting plate (7) stacked sequentially. The encapsulating film layer (4) encapsulates photovoltaic cells (3). The heat-conducting plate (7) is a gridded heat-conducting plate, and heat-conducting pipes (8) are provided on the heat-conducting plate (7). When cooling is performed, the cooling medium enters from the inlet of the heat-conducting pipe (8), flows inside the heat-conducting pipe (8), and flows out from the outlet of the heat-conducting pipe (8). The cooling medium carries away the heat inside the photovoltaic curtain wall assembly.

2. The photovoltaic curtain wall assembly of claim 1, wherein, The heat-conducting plate (7) includes a heat-conducting adhesive layer (71) and a heat-conducting surface (72) that are stacked together. The heat-conducting adhesive layer (71) is bonded to the back glass (6). At least a portion of the heat-conducting pipe (8) is embedded in the heat-conducting surface (72). When cooling is performed, the cooling medium flows in the heat-conducting pipe (8) and carries away the heat in the surrounding heat-conducting surface (72).

3. The photovoltaic curtain wall assembly of claim 1, wherein, The heat-conducting pipe (8) is designed as an array of multiple interconnected hexagons, so that the resistance of the cooling medium flowing in all directions is almost the same, which can reduce the resistance of the cooling medium flow and make the heat absorbed in the cooling medium evenly distributed without obvious stagnation areas or temperature accumulation areas.

4. The photovoltaic curtain wall assembly of claim 1, wherein, The side of the front glass (1) facing the encapsulating film layer (4) is coated with a colored glaze film layer (2).

5. The photovoltaic curtain wall assembly of claim 1, wherein, The decorative adhesive film layer (5) is black, used to highlight the colored glaze film layer (2).

6. The photovoltaic curtain wall assembly of claim 1, wherein, The front glass (1) is fully tempered ultra-clear glass with a thickness of 3.2mm to 13mm, and the back glass (6) is fully tempered glass with a thickness of 3.2mm to 13mm; the cooling medium is water.

7. A photovoltaic curtain wall system, characterized in that, include: The photovoltaic curtain wall assembly, the pipeline (12) connected to the photovoltaic curtain wall assembly, and the pump (13) connected to the pipeline (12) as described in any one of claims 1 to 6, wherein during cooling, the pump (13) provides power to the cooling medium and supplies the cooling medium to the photovoltaic curtain wall assembly through the pipeline (12), and the cooling medium is used for heating at the user end (16) after flowing out of the photovoltaic curtain wall assembly.

8. The system of claim 7, wherein, The photovoltaic curtain wall components are multiple, and the photovoltaic curtain wall components are connected in parallel on the pipeline (12).

9. The system of claim 7, wherein, A valve (14) is installed on the pipeline (12).

10. The system of claim 7, wherein, A storage box (15) is provided on the outlet pipe of the heat conduction pipe (8) connecting the photovoltaic curtain wall component. The cooling working fluid is stored in the storage box (15), and the storage box (15) is connected to the user terminal (16).
