Description

Technical Field

[0001] This invention relates to a photovoltaic module, specifically to an integrated structure of a frame cavity heat dissipation photovoltaic module. Background Technology

[0002] Traditional photovoltaic module products mainly consist of a front transparent glass panel, a front EVA (ethylene-vinyl acetate copolymer) film, a crystalline silicon solar cell, a rear EVA film, and a TPT (polyvinyl fluoride composite film) backsheet, which are assembled and laminated together, and then framed with an aluminum alloy frame.

[0003] Existing technology discloses an integrated photovoltaic module structure, which includes a secondary waterproof membrane, a photovoltaic module integrated on the front side of the secondary waterproof membrane, and an adhesive layer disposed between the front side of the secondary waterproof membrane and the photovoltaic module. A hot air welding area is provided on the back side of the secondary waterproof membrane. Hot air welding is performed by attaching the hot air welding area on the back side of the secondary waterproof membrane to the hot air welding area on the front side of the main waterproof membrane on the roof structure, thereby fixing the photovoltaic module to the roof structure. This method improves the stability of the photovoltaic module connection compared to structural adhesive bonding.

[0004] A search revealed an existing patent (publication number: CN218352434U) that discloses a building-integrated photovoltaic (BIPV) module support. In use, a first return spring engages with a first rectangular rod, and a locking block engages with a first slot, allowing for simultaneous adjustment of the lengths of the two longitudinal rods. This enables adaptive adjustment based on the size of the photovoltaic panels to meet usage requirements. However, the inventors discovered the following problem with the existing technology during the development of this invention: In use, the horizontal and vertical rods are positioned relative to the building roof. During positioning, the supporting surface formed by the horizontal and vertical rods is parallel to the roof. Under this condition, when the roof is horizontal or its angle is unsuitable for the required angle of sunlight, it is difficult to meet the installation requirements of the photovoltaic panels.

[0005] In view of this, the present invention designs an integrated structure for a frame cavity heat dissipation photovoltaic module. Summary of the Invention

[0006] The main objective of this disclosure is to provide an integrated structure for a frame cavity heat dissipation photovoltaic module, so as to effectively solve the problems raised by the inventors in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An integrated structure for a frame cavity heat dissipation photovoltaic module includes an integrated photovoltaic structure, a triangular support base, a lifting column, and a photovoltaic layout beam; The integrated photovoltaic structure consists of an aluminum alloy frame, a photovoltaic structure, and a heat dissipation cavity frame. The heat dissipation cavity frame is fixedly installed inside the aluminum alloy frame, and the photovoltaic structure is installed on the aluminum alloy frame and wraps the heat dissipation cavity frame. At least four inverted T-shaped sliders arranged in a rectangular array are fixedly connected to the bottom of the aluminum alloy frame. The top of the lifting column is fixedly connected to the bottom of the photovoltaic layout beam. The bottom end of the lifting column is movably installed on the triangular support base. A limit opening is opened at the top of the photovoltaic layout beam, and the inverted T-shaped sliders are limited to slide within the limit opening.

[0008] Preferably, the photovoltaic structure includes solar cells, tempered glass, an insulating layer, and a heat insulation plate. The tempered glass is bonded to the solar cells, and the solar cells are fixedly installed on the upper surface of the heat dissipation cavity frame. The insulating layer is fixedly connected to the heat insulation plate, and the insulating layer is fixedly connected to the lower surface of the heat dissipation cavity frame.

[0009] Preferably, the reinforced glass, battery cell, heat dissipation cavity frame, insulating layer, and heat insulation plate are sequentially encapsulated within an aluminum alloy frame from top to bottom.

[0010] Preferably, the heat dissipation cavity frame has a chamber inside, and a drive motor is fixedly installed in the chamber. The output end of the drive motor is fixedly connected to a second gear. The bottom of the heat dissipation cavity frame has several evenly distributed heat dissipation holes. A fan shaft is rotatably installed inside the heat dissipation cavity frame. A first gear is fixedly installed on the fan shaft, and the second gear meshes with the first gear for transmission.

[0011] Preferably, a shape memory alloy spring is fixedly connected to the cavity, and a first metal plate is fixedly connected to the other end of the shape memory alloy spring. The first metal plate is slidably connected to the cavity, and a second metal plate is fixedly connected to the inner wall of the cavity, with the second metal plate located above the first metal plate.

[0012] Preferably, the first metal sheet and the second metal sheet are electrically connected to the drive motor.

[0013] Preferably, the triangular support base has a linear slide rail groove, and a guide shaft is fixedly installed in the linear slide rail groove. Two symmetrically arranged hinged movable seats are slidably installed on the guide shaft, and the hinged movable seats are detachably installed on the triangular support base by positioning screws. An inclined frame is movably connected to the hinged movable seat, and a piston support rod is movably connected to the other end of the inclined frame. The other end of the piston support rod is hinged to the lifting column.

[0014] Preferably, the top of the aluminum alloy frame is provided with a mating groove, and a locking cover is fixedly installed in the mating groove by fastening bolts. The middle part of the locking cover is made of elastic material, and two adjacent aluminum alloy frames are aligned and connected by the locking cover.

[0015] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, the integrated photovoltaic structure is composed of aluminum alloy frame, heat insulation board, insulation layer, solar cells, tempered glass, heat dissipation cavity frame and other structures. The structure is stable and firm. The heat insulation board can be waterproof, windproof and heat-insulating. The solar cells can generate both electricity and heat energy, improve the comprehensive utilization efficiency of solar energy, meet the user's electricity demand and have broad prospects.

[0016] (ii) In this application, the shape memory alloy spring has the benefit of detecting temperature. If the temperature of the photovoltaic module rises, the shape memory alloy spring will extend, causing the first metal sheet to slide in the cavity and contact and press against the second metal sheet, thereby starting the drive motor. The drive motor drives the first gear to rotate. Under the meshing transmission action of the first gear and the second gear, the fan shaft will rotate, thereby dissipating the internal heat through the heat dissipation holes to quickly reduce the temperature of the photovoltaic module.

[0017] (III) In this application, the inverted T-shaped slider at the lower end of the integrated photovoltaic structure is limited in the limiting opening of the photovoltaic layout beam, so that it can be laid out and supported. The triangular support base and the lifting column provide support force and make the local area relatively stable and prevent it from tilting. The height of the integrated photovoltaic structure can also be adjusted according to actual needs. The hinged movable seat can slide on the guide shaft, that is, the distance between the two hinged movable seats in the linear slide rail groove changes. The smaller the distance, the greater the height of the integrated photovoltaic structure, and vice versa. Moreover, the integrated photovoltaic structure can also be combined, making it flexible and versatile. Attached Figure Description
