Description

Technical Field

[0001] This utility model relates to the field of building photovoltaic technology, and more specifically, to a photovoltaic window frame and a window structure including the same. Background Technology

[0002] Photovoltaic glass is a novel high-tech architectural glass product that seals solar cells between low-iron glass and a back glass layer using a film. It uses low-iron glass to cover the solar cells, ensuring greater light transmittance and thus generating more electricity. However, photovoltaic windows have weak fire resistance, making them unsuitable for locations with strict fire safety requirements, such as substations. Furthermore, photovoltaic windows require sophisticated photovoltaic encapsulation structures, which hinders cost reduction. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a photovoltaic window frame and a window structure including the same, which can significantly reduce fire hazards compared to photovoltaic windows.

[0004] The primary objective of this invention is to provide a photovoltaic window frame, comprising a window frame body with a central hollow section and several first photovoltaic elements. The window frame body is constructed by connecting several beams end to end in sequence, and the several first photovoltaic elements are disposed on the forward-facing surfaces of the several beams.

[0005] The window frame is an essential structural element of the window. This solution abandons the common practice of directly replacing traditional window glass with photovoltaic glass. Instead, the photovoltaic elements are installed on the window frame. After absorbing solar energy and heating up, the photovoltaic elements are primarily conducted to the window frame, preventing excessive heat radiation into the room and thus avoiding fire hazards. Furthermore, this solution achieves the same goal using conventionally packaged photovoltaic elements, significantly reducing installation costs. In addition, this solution places the first photovoltaic element on the forward-facing surface of the beam, allowing it to receive sunlight for extended periods during the day, generating sufficient electricity.

[0006] In some embodiments, a plurality of first fasteners are also included, with one first fastener on each side of the forward-facing surface of the beam in the width direction. The first end of the first fastener is fixedly connected to the beam, and the second end of the first fastener protrudes relative to the forward-facing surface of the beam and is provided with a groove for fastening the first photovoltaic element.

[0007] This solution can improve the strength of the first photovoltaic element installed on the beam, and prevent the first photovoltaic element from easily detaching from the window frame body.

[0008] In some embodiments, the first end of the first buckle member includes a limiting part, and the surface of the beam member corresponding to the position of the limiting part is provided with a groove for limiting the limiting part.

[0009] This solution can improve the connection strength between the first fastener and the window frame body, thereby improving the connection stability between the first photovoltaic element and the window frame body.

[0010] In some embodiments, a first buffer is provided between the first photovoltaic element and the corresponding groove; and / or, a second buffer is provided between the first photovoltaic element and the forward-facing surface of the corresponding beam.

[0011] This solution prevents the first photovoltaic element from making hard contact with the first fastener and the window frame body, thus protecting the first photovoltaic element. In addition, the buffer supports the first photovoltaic element, thereby setting a distance between the first photovoltaic element and the window frame body, which can reduce the heat transfer level from the first photovoltaic element to the window frame body, thereby reducing the temperature rise of the window frame body and reducing the fire hazard.

[0012] In some embodiments, a plurality of second photovoltaic elements are also included, which are disposed on the upward-facing surfaces of the plurality of beams.

[0013] The second photovoltaic element can receive prolonged sunlight exposure during the day, increasing the photovoltaic window frame's ability to generate electricity.

[0014] In some embodiments, the window frame body is a hollow rectangular structure, and the plurality of beams include a first horizontal beam, a first vertical beam, a second horizontal beam, and a second vertical beam connected end to end. The front surface of the first horizontal beam, the front surface of the first vertical beam, the front surface of the second horizontal beam, and the front surface of the second vertical beam are all provided with the first photovoltaic element, and the upper surface of the first horizontal beam and the upper surface of the second horizontal beam are all provided with the second photovoltaic element.

[0015] In some embodiments, the first photovoltaic element includes a first photovoltaic cell component and a pair of first tempered glass components attached to both sides of the first photovoltaic cell component.

[0016] In some embodiments, the second photovoltaic element includes a second photovoltaic cell component and a pair of second tempered glass components attached to both sides of the second photovoltaic cell component.

[0017] In some embodiments, a plurality of second fasteners are also provided, with one second fastener on each side of the upward-facing surface of the beam member in the width direction, and the surface of the second fastener facing the second photovoltaic element having a fastening portion for fastening the second photovoltaic element.

[0018] In some embodiments, the latching portion is a protruding structure, and the surface of the second photovoltaic element facing the corresponding protruding structure is provided with a recessed structure. The protruding structure and the recessed structure cooperate one by one to make the second latching member fasten the second photovoltaic element.

[0019] This solution can improve the connection stability between the second photovoltaic element and the window frame body.

[0020] In some embodiments, a third buffer is provided between the second photovoltaic element and the upward-facing surface of the corresponding beam element.

[0021] In this design, the buffer can support the second photovoltaic element, thereby setting a distance between the second photovoltaic element and the window frame body. This effectively reduces the heat conduction level to the window frame body, thereby reducing the temperature rise of the window frame body, reducing the fire hazard, and also preventing hard contact with the window frame body, thus extending the service life of the second photovoltaic element.

[0022] In some embodiments, the beams are all quadrangular prisms.

[0023] The second objective of this invention is to provide a window structure, including a window body and a photovoltaic window frame, wherein the photovoltaic window frame spacing is located in front of the window body.

[0024] In this solution, the photovoltaic window frame does not directly contact the window body. Therefore, the heat generated by the photovoltaic window frame after absorbing solar energy has a smaller impact on the window body, effectively preventing the fire hazard caused by the rise in window body temperature.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the photovoltaic element on the window frame, the photovoltaic element absorbs solar energy and heats up, and then mainly conducts the heat to the window frame, which significantly reduces the heat transfer level to the window body, thus avoiding excessive heat radiation into the room and causing fire hazards. In addition, the photovoltaic element does not require special packaging, which significantly reduces the installation cost, and it can be exposed to sunlight for a long time during the day to generate sufficient electricity.

Detailed Implementation

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0035] Example 1

[0036] like Figure 1-2 As shown, this embodiment provides a photovoltaic window frame, including a window frame body 100 with a hollowed-out center and a plurality of first photovoltaic elements 200. The window frame body 100 is formed by a plurality of beams connected end to end in sequence, and the plurality of first photovoltaic elements 200 are disposed on the front-facing surface of the plurality of beams.

[0037] It is understood that the window frame is a necessary structure for the window. This utility model abandons the conventional method of directly replacing traditional window glass with photovoltaic glass. Instead, the photovoltaic element is set on the window frame. After absorbing solar energy and heating up, the photovoltaic element is mainly conducted to the window frame. In specific implementation, the window frame and the window body are separated, which is sufficient to significantly reduce the heat transfer from the photovoltaic element to the window body, thereby avoiding excessive heat radiation into the room and causing fire hazards. At the same time, since the heat transfer effect is significantly reduced and it is not necessary to require the photovoltaic element to be transparent on both sides like a photovoltaic window, the cost of the photovoltaic element can also be significantly reduced. In specific implementation, in order to facilitate the installation of the first photovoltaic element 200, the beams are all made of four-sided prism aluminum. The four-sided prism has a flat surface, which makes it easy for the first photovoltaic element 200 to be pressed against the front surface of the beam. Moreover, the front surface of the four-sided prism faces directly forward. During construction, the photovoltaic window frame is set on the wall surface and protrudes relative to the wall. Sunlight usually shines on the photovoltaic window frame from the upper side. At this time, the first photovoltaic element 200 can fully absorb solar energy and improve the efficiency of power generation.

[0038] In some other embodiments, the beam can also be implemented in other prism forms, wherein the forward-facing surface may be slightly tilted upwards or slightly tilted upwards, in which case it does not affect the first photovoltaic element 200 from fully receiving solar energy.

[0039] like Figure 3-5 As shown, it also includes several first fasteners 300. One first fastener 300 is provided on each side of the forward-facing surface of the beam member in the width direction. The first end of the first fastener 300 is fixedly connected to the beam member, and the second end of the first fastener 300 protrudes relative to the forward-facing surface of the beam member and is provided with a groove 310 for fastening the first photovoltaic element 200. In specific implementation, to improve the fastening strength of the first photovoltaic element 200, the groove 310 has a preset extension length in the length direction of the forward-facing surface of the beam member. The opening directions of a pair of grooves 310 are opposite, and the width direction of the first photovoltaic element 200 is limited by a corresponding pair of grooves 310. Preferably, the length of the groove 310 is equivalent to the length of the corresponding beam member to improve the support and limiting strength of the first photovoltaic element 200.

[0040] like Figure 5 As shown, the first end of the first fastener 300 includes a limiting part 320, which, in conjunction with... Figure 3-4 The surface of the beam member corresponding to the position of the limiting part 320 is provided with a slot 150 for limiting the limiting part 320. In specific implementation, the first fastener 300 includes a limiting part 320 forming a groove 310 with a right-angle connection. It is easy to understand that the limiting part 320 can be attached to a surface perpendicular to the forward-facing surface of the beam member. Continuing to refer to Figure 3-4 Taking a beam member using a quadrangular prism as an example, the groove 310 protrudes from the front surface of the quadrangular prism, and the limiting part 320 is attached to the upper or lower surface of the quadrangular prism. Specifically, the limiting part 320 is a plate with a preset length. In order to facilitate processing, the length of the limiting part 320 is the same as the length of the groove 310. At this time, the length of the slot 150 is slightly longer than the limiting part 320 or the two lengths are equal, so that the limiting part 320 can be stably limited in the slot 150, and the first fastener 300 forms a stable connection with the window frame body 100.

[0041] refer to Figure 3-4 In order to provide protection for the first photovoltaic element 200, a first buffer 400 is provided between the first photovoltaic element 200 and the corresponding groove 310. In specific implementation, the first buffer 400 can be made of plastic. Preferably, the outer contour of the first buffer 400 matches the inner wall contour of the groove 310, so that the first buffer 400 is locked inside the groove 310. In this way, the first photovoltaic element 200 can be prevented from making hard contact with the first buckle 300, thus protecting the first photovoltaic element 200.

[0042] refer to Figure 3 A second buffer 410 is provided between the first photovoltaic element 200 and the forward-facing surface of the corresponding beam element. In this way, the second buffer 410 can support the first photovoltaic element 200, thereby distancing the first photovoltaic element 200 from the surface of the window frame body 100. This reduces the heat transfer level from the first photovoltaic element 200 to the window frame body 100, thereby reducing the temperature rise of the window frame body 100 and reducing the fire hazard. At the same time, it can avoid hard contact between the first photovoltaic element 200 and the frame, effectively extending the service life of the first photovoltaic element 200.

[0043] refer to Figure 1-3 It also includes several second photovoltaic elements 500, which are disposed on the upward-facing surfaces of several beams. In specific implementation, the beams are made of aluminum prisms. At this time, the upward-facing surfaces of the beams are directly upward, which is the upper surface of the prisms. The photovoltaic window frame is placed on the wall surface and protrudes relative to the wall. Sunlight usually shines on the photovoltaic window frame from the upper side. At this time, the second photovoltaic elements 500 can fully absorb solar energy and improve the efficiency of power generation.

[0044] In other embodiments, the beam can also be implemented in other prismatic forms, wherein the upward-facing surface may be slightly tilted forward or slightly tilted backward, in which case it does not affect the first photovoltaic element 200 from fully receiving solar energy.

[0045] refer to Figure 1-2 In some embodiments, the window frame body 100 is a hollow rectangular structure, and several beams include a first horizontal beam 110, a first vertical beam 120, a second horizontal beam 130, and a second vertical beam 140 connected end to end. In specific implementation, in order to improve the power generation capability, the front surfaces of the first horizontal beam 110, the first vertical beam 120, the second horizontal beam 130, and the second vertical beam 140 are all provided with first photovoltaic elements 200, and the upper surfaces of the first horizontal beam 110 and the second horizontal beam 130 are all provided with second photovoltaic elements 500.

[0046] refer to Figure 3-4 The device also includes several second fasteners 600. One second fastener 600 is provided on each side of the upward-facing surface of the beam member in the width direction. The surface of the second fastener 600 facing the second photovoltaic element 500 is provided with a fastening part for fastening the second photovoltaic element 500. In specific implementation, the fastening part is a protruding structure 610. The surface of the second photovoltaic element 500 facing the corresponding protruding structure 610 is provided with a recessed structure 510. The protruding structure 610 and the recessed structure 510 cooperate one by one to make the second fastener 600 fasten the second photovoltaic element 500.

[0047] In addition, a third buffer 700 is provided between the second photovoltaic element 500 and the upward-facing surface of the corresponding beam element. The third buffer 700 can support the second photovoltaic element 500, thereby distancing the second photovoltaic element 500 from the window frame body 100. This effectively reduces the heat conduction level to the window frame body 100, thereby reducing the temperature rise of the window frame body 100, reducing the fire hazard, and also preventing the second photovoltaic element 500 from making hard contact with the window frame body 100, thus extending the service life of the second photovoltaic element 500.

[0048] In practice, the first buffer 400, the second buffer 410, and the third buffer 700 can be implemented using an adhesive material layer. This provides buffering protection while also ensuring that the first photovoltaic element 200 and the second photovoltaic element 500 are bonded to the window frame body 110, significantly improving the connection strength. Preferably, the adhesive material layer can be made using adhesives with high-temperature resistance, such as silicone structural adhesive. This further reduces the heat transfer capacity of the photovoltaic elements to the window frame body, thereby reducing the fire risk.

[0049] refer to Figure 3 The first photovoltaic element 200 includes a photovoltaic cell component 210 and a pair of tempered glass components 220 attached to both sides of the photovoltaic cell component 210; and / or, the second photovoltaic element 500 includes a photovoltaic cell component 210 and a pair of tempered glass components 220 attached to both sides of the photovoltaic cell component 210.

[0050] In addition, to increase the power generation of the photovoltaic window frame, in some other embodiments, photovoltaic elements can also be installed on other surfaces of the window frame body 100, as shown in the reference. Figure 1-2 To illustrate, taking a rectangular frame as an example, photovoltaic elements can be added to the outer and / or inner surfaces of the rectangle in the left and right directions. It is easy to understand that when sunlight shines on the photovoltaic window frame from above at an angle, the photovoltaic elements can also be subjected to oblique sunlight at certain times, thereby generating electricity.

[0051] Example 2

[0052] like Figure 6-7 As shown, this embodiment provides a window structure, including a window body 20 and a photovoltaic window frame 10 of Embodiment 1. The photovoltaic window frame 10 is positioned in front of the window body 20. In specific implementation, an installation cavity 40 extending into the interior is opened on the surface of the wall 30. The window body 20 is placed inside the installation cavity 40, and the front end of the window body 20 is spaced apart from the surface of the outer wall 30. By installing the photovoltaic window frame 10 on the outer surface of the wall 30, and with beams distributed around the opening of the installation cavity 40 on the outer surface of the wall 30, a gap is left between the photovoltaic window frame 10 and the window body 20, preventing the heat generated by the photovoltaic window frame 10 after absorbing solar energy from being directly conducted to the window body 20.

[0053] refer to Figure 7 When the window structure is used in a substation, in order to improve the fire resistance, the window body 20 is also equipped with a fire-resistant component 50. In specific implementation, since the photovoltaic window frame 10 is the main heat source, the fire-resistant component 50 is set on the front surface of the window body 20 to be close to the heat source. In practice, the fire-resistant component 50 includes silicone weather-resistant sealant and fire-extinguishing foam rods.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
