Description

Technical Field

[0001] The utility model relates to the field of photovoltaics, and specifically relates to a double-laminated insulating photovoltaic curtain wall. Background Art

[0002] With the continuous progress of solar energy technology and the reduction of costs, the application prospect of photovoltaic curtain walls is broad. In the future, photovoltaic curtain walls will be more intelligent, capable of achieving seamless connection with building energy management systems and improving energy utilization efficiency. At the same time, the design and manufacturing technologies of photovoltaic curtain walls will also continue to innovate, bringing more green solutions to the construction industry.

[0003] In the existing photovoltaic curtain wall, the back is occupied by the insulating layer, and the original wire outlet position on the back panel is occupied; this results in poor heat dissipation effect of the glass curtain wall and it is not aesthetically pleasing after installation.

[0004] The currently used ordinary photovoltaic curtain wall is composed of glass, EVA film, solar cells, EVA film and glass. The string outlet is on the back panel of the curtain wall, which leads to the non-compliance of the heat transfer coefficient, and the heat generated by the solar cells will also be transferred to the interior, causing the indoor temperature to rise. Content of the Utility Model

[0005] In view of the problems in the prior art, the utility model provides a double-laminated insulating photovoltaic curtain wall.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a double-laminated insulating photovoltaic curtain wall, including a frame, the frame is an aluminum alloy frame composed of horizontal sub-frames and vertical sub-frames, multiple solar cells are arranged on the frame, wires are arranged at the output ends of the solar cells, and a junction box is arranged at the end of the wires.

[0007] Preferably, two groups of glass components are arranged on one side of the frame, and an insulating layer is arranged between the two groups of glass components for heat insulation.

[0008] Preferably, structural glue is filled between the glass components and the frame. One group of the glass components consists of two pieces of glass, and an EVA film is arranged between the two pieces of glass.

[0009] Preferably, the other group of glass components consists of two pieces of glass and solar cells, and an EVA film is arranged between the solar cells and the glass.

[0010] Advantageous Effects:

[0011] In the prior art, for some green buildings with special requirements, the heat transfer coefficient may not meet the standard. Therefore, the method of increasing the hollow layer and increasing the thickness is adopted to reduce its heat transfer coefficient to meet the standard. And placing the solar cells outside the curtain wall can alleviate the rise in indoor temperature caused by the heat generated during the power generation of the solar cells. Since the back of the curtain wall is occupied by the hollow layer, the photovoltaic curtain wall in this case exits the wire from the side and uses a side wiring box to solve the problem that the original backplane wire outlet position is occupied.

A plurality of solar cells 3 are provided on the frame 1, a wire 4 is provided at the output end of the solar cell 3, and a wiring box 5 is provided at the end of the wire 4.

[0019] Since the back of the curtain wall is occupied by the hollow layer 7, the photovoltaic curtain wall 7 exits the wire from the side and uses the wire 4 to connect the wiring box 5 on the side to solve the problem that the original backplane wire outlet position is occupied.

[0020] Two groups of glass members are provided on one side of the frame 1, and a hollow layer 7 is provided between the two groups of glass members, and the hollow layer 7 is used to isolate heat.

[0021] A structural adhesive 8 is filled between the glass member and the frame 1. One group of the glass members is composed of two pieces of glass, and an adhesive film 6 is provided between the two glass plates 2.

[0022] Another group of the glass members consists of two glass plates 2 and a battery cell 3, and an adhesive film 6 is provided between the battery cell 3 and the glass plate 2.

[0023] By adopting the method of increasing the hollow layer 7 and increasing the thickness, its heat transfer coefficient is reduced to meet the standard. And placing the battery cell 3 outside the curtain wall can alleviate the rise in indoor temperature caused by the power generation and heat generation of the battery cell 3.
