Description

Technical Field

[0001] This utility model relates to the field of solar panel technology, and in particular to a solar panel with improved heat dissipation performance. Background Technology

[0002] Solar panels are devices that convert solar energy into electrical energy. The working principle of solar panels is based on the photovoltaic effect: when sunlight shines on a solar cell, photons (the energy units of light) are absorbed by the silicon material, exciting electrons in the silicon atoms to jump, forming charges and generating an electric field. Positive and negative electrons separate under the influence of the electric field, creating a potential difference, which in turn forms a current. This current is then conducted through conductive aluminum strips, outputting electrical energy. Solar panels also have advantages such as being environmentally friendly and energy-saving, low-cost, highly reliable, and easy to maintain.

[0003] Solar cells are sealed inside the device. Due to the restricted air convection in the sealed environment, heat dissipation becomes more difficult. Traditional active cooling methods, such as using fans or other cooling devices to enhance the cooling effect, are effective but increase the system's energy consumption and complexity. Therefore, there is a need to propose a solar panel that can improve heat dissipation to solve the above problems. Utility Model Content

[0030] Example 1

[0031] like Figures 1-9 As shown,

[0032] A solar panel for improving heat dissipation includes an aluminum alloy frame 1, tempered glass 2, and a back panel 3. The tempered glass 2 is fixed to the upper surface of the aluminum alloy frame 1, and the back panel 3 is fixed to the lower surface of the aluminum alloy frame 1. Both the tempered glass 2 and the back panel 3 are fixedly connected to the inner sidewall of the aluminum alloy frame 1. A junction box 21 is fixedly connected to the lower end of the back panel 3.

[0033] In this embodiment, the upper surface of the tempered glass 2 is at the same height as the upper surface of the aluminum alloy frame 1, and the lower surface of the junction box 21 is located above the lower surface of the aluminum alloy frame 1.

[0034] Several ventilation holes 4 are provided on the front and rear side walls of the aluminum alloy frame 1. A fixing frame 5 is provided between two front and rear ventilation holes 4, and the fixing frame 5 is located in the space formed by the tempered glass 2 and the back plate 3. The fixing frame 5 has a hollow structure, and its front and rear ends are fixedly connected to the inner walls of the front and rear side walls of the aluminum alloy frame 1, respectively. The ventilation holes 4 are located inside the fixing frame 5, and ventilation holes 6 are provided on the side walls of the fixing frame 5. Adjacent fixing frames 5 do not contact each other. Through the combination of the ventilation holes 4, the hollow internal structure of the fixing frame 5, and the ventilation holes 6, a heat dissipation channel is formed.

[0035] A reflector 7 is provided on the inner side of the aluminum alloy frame 1. The reflector 7 is fixed on the back plate 3 and is located below the fixed frame 5. Battery pieces 8 are provided on the four outer side walls of the fixed frame 5. A waterproof and breathable membrane is provided between the battery pieces 8 and the outer side walls of the fixed frame 5.

[0036] A convex glass plate 9 is provided on the side of the battery cell 8 away from the fixed frame 5. The end of the convex glass plate 9 close to the battery cell 8 is set with a flat structure, and the end of the convex glass plate 9 away from the battery cell 8 is set with a convex structure. An EVA film is provided between the convex glass plate 9 and the battery cell 8. The EVA film ensures the light transmittance of the device at high temperatures.

[0037] In this embodiment, the heat dissipation holes 6 and ventilation holes 4 enable the battery cell 8 fixed on the fixed frame 5 to have good ventilation and heat dissipation without the need for additional fans or other heat dissipation devices, thereby reducing costs. The application of a waterproof and breathable membrane between the battery cell 8 and the fixed frame 5 allows the battery cell 8 to dissipate heat while preventing moisture from entering, ensuring the normal operation of the battery cell 8.

[0038] In this embodiment, the fixed frame 5 has a diamond-shaped cross-section. Heat dissipation holes 6 are provided on the four side walls of the fixed frame 5, and battery cells 8 are provided on the four outer side walls of the fixed frame 5. When in use, light directly acts on the two upper battery cells 8, while some light shines on the reflector 7 through the gap between the two fixed frames 5. The reflector 7 then acts on the two lower battery cells 8, thereby greatly improving the power generation efficiency of the device.

[0039] To improve the ease of installation, sliding cavities 12 are provided on both the front and rear side walls of the aluminum alloy frame 1. Heat dissipation and ventilation holes 4 are opened on the inner wall of the sliding cavity 12. Limiting slides 13 are opened on the side walls of the two sliding cavities 12 that are far apart from each other. A sliding block 14 is slidably connected in the sliding cavity 12. A fixing plate 15 is fixedly connected to the end of the sliding block 14 that is away from the heat dissipation and ventilation hole 4. The end of the fixing plate 15 that is away from the sliding block 14 passes through the limiting slide 13 and extends to the outside of the aluminum alloy frame 1. The fixing plate 15 is slidably connected to the limiting slide 13. A fixing hole 16 is opened on the fixing plate 15.

[0040] Several locking plates 17 are provided on the upper part of the front and rear side walls of the aluminum alloy frame 1. The locking plates 17 are located directly above the sliding block 14. The upper side wall of the sliding cavity 12 is provided with a limiting slide rail 22. A locking bolt 18 is provided on the upper part of the locking plate 17. The lower end of the locking bolt 18 passes through the locking plate 17 and through the limiting slide rail 22 to be threadedly connected to the upper end of the sliding block 14. The locking bolt 18 is rotatably connected to the locking plate 17.

[0041] In this embodiment, the solar panel can be installed by cooperating with the fixing bracket below the solar panel through the fixing hole 16 on the fixing plate 15. The sliding block 14 can slide in the sliding cavity 12, thereby driving the fixing plate 15 to slide in the limiting slide rail 13, ensuring that the device can be installed and fixed on support frames of different sizes, and improving the adaptability of the device.

[0042] The upper ends of the front and rear side walls of the aluminum alloy frame 1 are provided with anti-slip groove 19, and the lower end of the locking plate 17 is provided with anti-slip groove 20. The locking plate 17 and the anti-slip groove 20 on the aluminum alloy frame 1 cooperate with the anti-slip groove 19 to improve the firmness between the sliding block 14 and the aluminum alloy frame 1.

[0043] Limiting grooves 10 are provided at the lower ends of both sides of the aluminum alloy frame 1, and limiting plates 11 are attached to the upper ends of both sides of the aluminum alloy frame 1. The length and width of the limiting plates 11 are less than the length and width of the limiting grooves 10. The setting of the limiting grooves 10 and the limiting plates 11 makes the device more stable when stacked, effectively avoiding the problem of poor safety when solar panels are directly stacked. At the same time, the height of the limiting plates 11 is greater than the depth of the limiting grooves 10, preventing the junction box 21 from squeezing the tempered glass 2.

[0044] When using this utility model:

[0045] First, loosen the locking bolt 18, pull the fixing plate 15 to slide within the limiting slide 13, causing the sliding block 14 to slide within the sliding cavity 12, and the locking bolt 18 to move within the limiting slide 22. After moving to the appropriate position, tighten the locking bolt 18. Use the locking plate 17 and the anti-slip groove 20 and anti-slip groove 19 on the aluminum alloy frame 1 to improve the firmness between the sliding block 14 and the aluminum alloy frame 1. Then, the installation of the solar panel can be achieved by cooperating with the fixing bracket below the solar panel through the fixing hole 16 on the fixing plate 15.

[0046] Then, during use, because the device has heat dissipation and ventilation holes 4 on the adjacent side walls of the sliding cavities 12 on both the front and rear sides of the aluminum alloy frame 1, and a fixing frame 5 is set inside the aluminum alloy frame 1, with heat dissipation holes 6 on the side walls of the fixing frame 5, the combination of heat dissipation holes 6 and ventilation holes 4 allows the battery cells 8 fixed on the fixing frame 5 to have good ventilation and heat dissipation without the need for additional fans or other heat dissipation devices, thus reducing costs. The application of a waterproof and breathable membrane between the battery cells 8 and the fixing frame 5 allows the battery cells 8 to dissipate heat while preventing moisture from entering, ensuring the normal operation of the battery cells 8.

[0047] In addition, during use, since the fixed frame 5 in this device is arranged in a diamond shape, battery cells 8 are arranged on the four outer walls of the fixed frame 5, and a reflector 7 is arranged below the fixed frame 5. At the same time, a convex glass plate 9 is arranged on the side of the battery cell 8 away from the fixed frame 5. During use, the light directly acts on the two upper battery cells 8, while some light shines on the reflector 7 through the gap between the two fixed frames 5. The reflector 7 then acts on the two lower battery cells 8, thereby greatly improving the power generation efficiency of the device.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
