[0032] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 Description The photovoltaic assembly 100 according to the embodiment of the present invention comprises: a photovoltaic panel 20, a mounting bracket 10 and a heat exchange assembly 30. The photovoltaic assembly 100 has a height direction A, a length direction B and a width direction C.

[0033] Specifically, if Figure 1-Figure 5 As shown, the photovoltaic panel 20 is rotatably connected to the mounting bracket 10 , and the heat exchange component 30 is disposed in the photovoltaic panel 20 , and the heat exchange component 30 exchanges heat with the photovoltaic panel 20 .

[0034] Combination Figure 1-Figure 5 The mounting bracket 10 extends along the height direction A of the photovoltaic module 100. The mounting bracket 10 also includes a mounting seat 11. The photovoltaic panel 20 is rotatably connected to one end of the mounting bracket 10 along the height direction A of the photovoltaic module 100. The mounting seat 11 is arranged at the other end of the mounting bracket 10 along the height direction A of the photovoltaic module 100. The photovoltaic panel 20 can rotate at a certain angle relative to the mounting bracket 10 along the movement trajectory of the sun. A sleeve 22 is formed on the surface of one side of the photovoltaic panel 20 adjacent to the mounting bracket 10 along the height direction A of the photovoltaic module 100. The sleeve 22 extends toward the mounting bracket 10 along the height direction A of the photovoltaic module 100. The sleeve 22 is open at one end away from the photovoltaic panel 20 along the height direction A of the photovoltaic module 100. The end of the mounting bracket 10 adjacent to the mounting plate along the height direction A is sleeved in the sleeve 22. The sleeve 22 and the mounting bracket 10 are matched through a connecting shaft, and the connecting shaft extends along the length direction B of the photovoltaic component 100. A first mounting hole is formed on the side wall of the sleeve 22 and penetrates the side wall of the sleeve 22 along the length direction B of the photovoltaic component 100. The end of the mounting seat 11 connected to the photovoltaic panel 20 along the height direction A is formed with a second mounting hole that penetrates the mounting seat 11 along the length direction B of the photovoltaic component 100. The connecting shaft is inserted into the first mounting hole and the second mounting hole, so that the photovoltaic panel 20 is connected to the mounting seat 11 and the photovoltaic panel 20 can rotate relative to the mounting seat 11 with the connecting shaft as the axis.

[0035] The photovoltaic panel 20 includes a battery cell 23. The photovoltaic panel 20 has a thickness direction. The battery cell 23 is arranged on a side of the photovoltaic panel 20 away from the mounting bracket 10 along the thickness direction. The heat exchange component 30 is opposite to the battery cell 23 along the thickness direction of the photovoltaic panel 20. The heat exchange component 30 is arranged on a side of the battery cell 23 adjacent to the mounting bracket 10 along the thickness direction of the photovoltaic panel 20. The heat exchange component 30 can exchange heat with the battery cell 23 to keep the battery cell 23 within a suitable operating temperature range, thereby maintaining or improving the power generation efficiency of the battery cell 23.

[0036] According to the photovoltaic assembly 100 of the embodiment of the utility model, the photovoltaic panel 20 is rotatably connected to the mounting bracket 10 so that the photovoltaic panel 20 can flexibly adjust the angle along the movement trajectory of the sun, thereby maximizing the efficiency of receiving sunlight and improving the power generation efficiency of the photovoltaic assembly 100. The photovoltaic panel 20 has a built-in heat exchange component 30. When the photovoltaic panel 20 is operated under high-intensity light, heat will accumulate. When the temperature of the photovoltaic panel 20 is high, the photoelectric conversion efficiency will be reduced. The heat exchange component 30 can absorb and take away the excess heat on the photovoltaic panel 20, so that the photovoltaic panel 20 is kept within a better operating temperature range, thereby maintaining or improving the power generation performance of the photovoltaic assembly 100, realizing flexible tracking, effective heat dissipation and long-term stable power output of the photovoltaic assembly 100, improving the utilization rate of solar energy, and enhancing the overall reliability of the photovoltaic assembly 100.

[0037] According to some embodiments of the present invention, Figure 2-5 As shown, the heat exchange assembly 30 includes: a plurality of heat exchange tubes 31, the plurality of heat exchange tubes 31 are connected to each other, the plurality of heat exchange tubes 31 include a plurality of first heat exchange tubes 32 and a plurality of second heat exchange tubes 33, the plurality of first heat exchange tubes 32 are arranged in the photovoltaic panel 20, and the plurality of second heat exchange tubes 33 are arranged in the mounting bracket 10.

[0038] The plurality of first heat exchange tubes 32 are connected to each other, and the plurality of first heat exchange tubes 32 are laid in the photovoltaic panel 20, and are opposite to the battery cell 23 along the thickness direction of the photovoltaic panel 20. The first heat exchange tube 32 is connected to the second heat exchange tube, and the plurality of second heat exchange tubes 33 extend along the height direction A of the photovoltaic assembly 100. The mounting bracket 10 defines an accommodation cavity inside, and the plurality of second heat exchange tubes 33 are passed through the accommodation cavity of the mounting bracket 10 along the height direction A of the photovoltaic assembly 100. The mounting bracket 10 is open at one end adjacent to the photovoltaic panel 20 along the height direction A to facilitate the communication between the second heat exchange tube 33 and the first heat exchange tube 32. The heat exchange medium circulates in the plurality of first heat exchange tubes 32 and the plurality of second heat exchange tubes 33. The heat exchange medium flows from the second heat exchange tube 33 into the first heat exchange tube 32, and flows out of the photovoltaic panel 20 from the second heat exchange tube 33 after circulating in the plurality of first heat exchange tubes 32.

[0039] Thus, multiple first heat exchange tubes 32 and multiple second heat exchange tubes 33 are connected to each other to form a complete closed circulation loop. The heat exchange medium circulates in the multiple heat exchange tubes 31, absorbs heat from the light panel during the flow process, and releases heat in the mounting bracket 10 part through heat exchange, thereby ensuring the effective transfer and dissipation of heat. The arrangement of multiple heat exchange tubes 31 is beneficial to enhancing the heat exchange efficiency of the heat exchange component 30.

[0040] According to some embodiments of the present invention, Figure 2-5 As shown, the plurality of second heat exchange tubes 33 are respectively connected to the two free ends of the plurality of first heat exchange tubes 32 which are connected end to end.

[0041] There can be two second heat exchange tubes 33, and multiple first heat exchange tubes 32 are connected end to end in sequence to form a complete pipeline. The pipeline formed after the multiple first heat exchange tubes 32 are connected includes two free ends, and the two free ends are respectively connected to the two second heat exchange tubes 33 to facilitate the inflow and outflow of the cooling medium.

[0042] Thus, the multiple second heat exchange tubes 33 are respectively connected to the two free ends of the multiple first heat exchange tubes 32 after being connected end to end to form a continuous heat transfer path, ensuring the continuous flow of the heat exchange medium in the heat exchange tubes 31, improving the heat exchange efficiency of the heat exchange component 30, and also helping to reduce the complexity of the internal pipelines of the heat exchange component 30, reducing the difficulty of installation and maintenance, while increasing the reliability and aesthetics of the system.

[0043] According to some embodiments of the present invention, Figure 3 As shown, the heat exchange assembly 30 also includes: a liquid tank 34 and a first driving member 35. The liquid tank 34 is arranged in the mounting bracket 10. The liquid tank 34 is formed with a liquid outlet 341 and a liquid return port 342. The liquid outlet 341 and the liquid return port 342 are respectively connected to one end of the corresponding second heat exchange tube 33 away from the first heat exchange tube 32; the first driving member 35 is connected to the liquid tank 34, and the first driving member 35 is suitable for driving the liquid in the liquid tank 34 to flow between the liquid tank 34 and the heat exchange tube 31.

[0044] The liquid tank 34 is arranged in the mounting seat 11, and the liquid outlet 341 on the liquid tank 34 is connected to one end of a second heat exchange tube 33, and the other end of the second heat exchange tube 33 is connected to a free end of a pipeline formed by connecting multiple first heat exchange tubes 32, and the other free end of the pipeline formed by connecting multiple first heat exchange tubes 32 is connected to one end of another second heat exchange tube 33, and the other end of the second heat exchange tube 33 is suitable for connecting with the liquid return port 342 of the liquid tank 34. The liquid tank 34 is suitable for storing heat exchange medium. The first driving member 35 is arranged on the liquid tank 34. The first driving member 35 can drive the heat exchange medium in the liquid tank 34 to flow in the heat exchange component 30. Under the action of the first driving member 35, the heat exchange medium flows out from the liquid outlet 341 of the liquid tank 34 into a second heat exchange tube 33, and flows through a plurality of connected first heat exchange tubes 32 in sequence to complete the heat exchange, and then enters another second heat exchange tube 33, and returns to the liquid tank 34 through the return liquid port 342 of the liquid tank 34, forming a closed circulation loop.

[0045] Therefore, the liquid tank 34 is suitable for storing heat exchange medium. The function of the first driving member 35 is to provide power to promote the circulation of the heat exchange medium in the heat exchange component 30. The first driving member 35 can control the flow rate of the heat exchange medium and optimize the heat exchange efficiency. The heat exchange component 30 enhances the control ability of the temperature of the photovoltaic panel 20 through active circulation, which can effectively prevent the photovoltaic panel 20 from overheating and protect the battery cell 23, thereby improving the overall power generation efficiency of the photovoltaic component 100.

[0046] According to some embodiments of the present invention, Figure 3 As shown, the liquid tank 34 is formed with a liquid inlet 343 , and the heat exchange component 30 further includes: a liquid valve 36 , which is arranged at the liquid inlet 343 , and is suitable for opening and closing the connection between the liquid tank 34 and the outside of the heat exchange component 30 .

[0047] The liquid valve 36 is installed at the liquid inlet 343. Its main function is to control the connection state between the liquid tank 34 and the outside of the heat exchange component 30. That is, the liquid valve 36 can open the liquid inlet 343 to allow external liquid to enter the liquid tank 34, or close the liquid inlet 343 to isolate the outside and maintain the system closed. Through the switch control of the liquid valve 36, it is convenient to add heat exchange medium, perform system maintenance (such as cleaning or replacing heat exchange medium), and check when necessary. This design increases the maintainability and flexibility of the heat exchange component 30 and reduces maintenance costs.

[0048] Therefore, the liquid inlet 343 is mainly used to replenish and replace the cooling medium in the liquid tank 34. The setting of the liquid valve 36 provides a control node for the liquid cooling system of the heat exchange component 30, enhances the adaptability, safety and maintenance convenience of the photovoltaic component 100, and can improve the overall stability of the photovoltaic component 100 and extend the service life of the photovoltaic component 100.

[0049] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, it also includes: a rotating assembly 40, the rotating assembly 40 is arranged in the mounting bracket 10, and the rotating assembly 40 is suitable for driving the photovoltaic panel 20 to rotate relative to the mounting bracket 10. The function of the rotating assembly 40 is to drive the photovoltaic panel 20 to rotate relative to the mounting bracket 10, and the photovoltaic panel 20 rotates following the change of the sun's position to ensure that the photovoltaic panel 20 is always at the best angle to receive sunlight. Therefore, the rotating assembly 40 is arranged inside the mounting bracket 10, which can reduce the mechanical parts exposed to the outside and improve the overall aesthetics and durability of the photovoltaic assembly 100. The rotating assembly 40 can ensure that the photovoltaic panel 20 can remain stable and correctly align with the sun even in strong winds or other severe weather conditions, effectively improving the reliability of the long-term operation of the photovoltaic assembly 100.

[0050] According to some embodiments of the present invention, Figure 2-4 As shown, the rotating assembly 40 includes: a second driving member 41 and a flexible connecting member 43, the second driving member 41 is arranged in the mounting bracket 10; one end of the flexible connecting member 43 is connected to the second driving member 41, and the other end of the flexible connecting member 43 passes through the mounting bracket 10 and is connected to the photovoltaic panel 20.

[0051] The mounting bracket 10 includes a mounting column 12 and a mounting seat 11. The mounting column 12 extends along the height direction A of the photovoltaic assembly 100. One end of the mounting column 12 away from the photovoltaic panel 20 along the height direction A of the photovoltaic assembly 100 is fixedly connected to the mounting seat 11. The interiors of the mounting column 12 and the mounting seat 11 are both hollow structures, and the interior of the mounting column 12 is connected to the interior of the mounting seat 11. The second driving member 41 is arranged in the mounting seat 11. The second driving member 41 mainly provides power for the rotating assembly 40. The flexible connecting member 43 is penetrated in the mounting column 12. One end of the flexible connecting member 43 is connected to the second driving member. The other end of the flexible connecting member 43 is suitable for being fixedly connected to one end of the photovoltaic panel 20 along the width direction C of the photovoltaic assembly 100. The second driving member 41 can control the length of the flexible connecting member 43, and then pull one end of the photovoltaic panel 20 along the width direction C through the flexible connecting member 43 to control the photovoltaic panel 20 to rotate a certain angle, so as to achieve the angle adjustment of the photovoltaic panel 20.

[0052] Therefore, the second driving member 41 is arranged inside the mounting bracket 10, which helps to protect the driving component from the influence of external environmental factors, thereby improving the reliability and service life of the driving component. The setting of the flexible connecting member 43 can ensure the smooth transmission of force, allowing the photovoltaic panel 20 to rotate freely within a certain range without being affected by rigid constraints, which can reduce the mechanical wear of the rotating component 40, increase the durability of the rotating component 40, make the rotation of the photovoltaic panel 20 smoother, and ensure the stability of the entire photovoltaic system. The flexible connecting member 43 can adapt to more diverse installation conditions and angle requirements, so that the rotating component 40 can control the movement of the photovoltaic panel 20 more efficiently, flexibly and reliably.

[0053] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, it also includes: a first rotating member 44 , which is disposed on the mounting bracket 10 , the first rotating member 44 is pivotally connected to the mounting bracket 10 , and the flexible connecting member 43 is hung on the first rotating member 44 .

[0054] The first rotating member 44 can rotate on its own. The first rotating member 44 is arranged inside the mounting bracket 10. The first rotating member 44 is arranged between the photovoltaic panel 20 and the mounting seat 11 along the height direction A of the photovoltaic component 100. The middle part of the flexible connecting member 43 is suitable for contacting the outer peripheral side of the first rotating member 44. When the second driving member 41 drives the flexible connecting member 43 to extend or contract, relative sliding occurs between the flexible connecting member 43 and the first rotating member 44. The sliding friction between the flexible connecting member 43 and the first rotating member 44 drives the first rotating member 44 to rotate on its own.

[0055] Therefore, the power generated by the second driving member 41 can be transmitted to the photovoltaic panel 20 through the flexible connecting member 43, thereby driving the photovoltaic panel 20 to rotate. The setting of the first rotating member 44 ensures the flexibility of power transmission, realizes efficient power conversion and control, optimizes the spatial layout inside the mounting bracket 10, and ensures that the rotating component 40 can operate stably for a long time.

[0056] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the second driving member 41 includes a rotating shaft 45 , one end of the flexible connecting member 43 is connected to the rotating shaft 45 , and the rotating shaft 45 can wind up and release the flexible connecting member 43 .

[0057] The rotating shaft 45 indirectly drives the rotation of the photovoltaic panel 20 by winding and releasing the flexible connector 43. The second driving member 41 drives the rotating shaft 45 to rotate, and realizes the control of the retraction and release of the flexible connector 43. When the rotating shaft 45 rotates to make the flexible connector 43 wound on the rotating shaft 45, the flexible connector 43 pulls one end of the photovoltaic panel 20 to rotate toward the side where the mounting bracket 10 is located. When the rotating shaft 45 rotates in the opposite direction, the part of the flexible connector 43 wound on the rotating shaft 45 is released, and the sleeve 22 on the photovoltaic panel 20 connected to the mounting bracket 10 is arranged adjacent to the end of the photovoltaic panel 20 connected to the flexible connector 43 along the width direction C of the photovoltaic module 100. When the flexible connector 43 is relaxed, the force on one end of the photovoltaic panel 20 in the width direction C is reduced, and the end of the photovoltaic panel 20 connected to the flexible connector 43 rotates in the direction away from the mounting bracket 10 under the action of its own gravity.

[0058] Therefore, the second driving member 41 can accurately control the rotation speed and rotation angle of the photovoltaic panel 20 by controlling the rotation speed and rotation direction of the shaft 45, thereby providing the rotating component 40 with higher control accuracy and dynamic response capability. The shaft 45 is concentrated on the second driving member 41, which simplifies the structure of the entire rotating component 40 and reduces the complexity of external connections. The cooperation between the shaft 45 and the flexible connector 43 enables the rotating component 40 to achieve complex movements while maintaining a relatively low noise level and a small space occupancy, thereby ensuring the long-term stable operation of the rotating component 40.

[0059] According to some embodiments of the present invention, Figure 2 As shown, the first rotating member 44 and the rotating shaft 45 are opposite to each other in the vertical direction.

[0060] The first rotating member 44 and the rotating shaft 45 are arranged relative to each other along the height direction A of the photovoltaic component 100, which is beneficial to the rotating component 40 to achieve efficient mechanical transmission within the limited space of the mounting bracket 10. When the flexible connecting member 43 transmits power, the extension and contraction of the flexible connecting member 43 is more direct, avoiding interference with other components, thereby making higher utilization of the internal space of the mounting bracket 10, making the structure of the entire photovoltaic component 100 more compact, reducing energy loss during power transmission of the rotating component 40, and improving the driving efficiency of the second driving member 41.

[0061] According to some embodiments of the present invention, Figure 3 As shown, the invention further includes: at least one limiting member 46 , which is disposed on the rotating shaft 45 .

[0062] One end of the rotating shaft 45 is connected to the second driving member 41, and a stopper 46 is provided at the other end of the rotating shaft 45 away from the second driving member 41, or stoppers 46 are provided at both ends along the extending direction of the rotating shaft 45. Along the extending direction of the rotating shaft 45, the projection of the axial cross-sectional area is located inside the projection of the cross-sectional area of ​​the stopper 46, and the stopper 46 is used to form a limiting effect on the flexible connector 43 in the extending direction of the rotating shaft 45. Therefore, the setting of the stopper 46 is used to limit the flexible connector 43, prevent the flexible connector 43 from falling off the rotating shaft 45, improve the stability and reliability of the cooperation between the rotating shaft 45 and the flexible connector 43, and thus enhance the overall reliability of the photovoltaic module 100.

[0063] According to some embodiments of the present invention, Figure 2 and Figure 4 As shown, it also includes: a second rotating member 47, which is pivotally connected to the mounting bracket 10, and the second rotating member 47 is arranged between one end of the flexible connecting member 43 connected to the photovoltaic panel 20 and the first rotating member 44, and the second rotating member 47 is arranged adjacent to the second driving member 41 relative to the first rotating member 44 in the vertical direction, and the flexible connecting member 43 is hung on the second rotating member 47.

[0064] A connection hole 13 is formed on the side wall of the mounting column 12, and the connection hole 13 penetrates the side wall of the mounting column 12. The second rotating member 47 is pivotally disposed in the connection hole 13, and the second rotating member 47 can rotate. Along the height direction A of the photovoltaic assembly 100, the height of the second rotating member 47 is lower than that of the first rotating member 44. The flexible connecting member 43 is sequentially hung on the first rotating member 44 and the second rotating member 47, and the second rotating member 47 is located between the connection end of the flexible connecting member 43 and the photovoltaic panel 20 and the first rotating member 44.

[0065] When the second driving member 41 drives the rotating shaft 45 to rotate so that part of the flexible connecting member 43 is wound around the rotating shaft 45, under the action of the flexible connecting member 43, the first rotating member 44 rotates clockwise, and the second rotating member 47 rotates counterclockwise, and the flexible connecting member 43 pulls one end of the photovoltaic panel 20 to rotate toward one side of the mounting bracket 10.

[0066] When the second driving member 41 drives the rotating shaft 45 to rotate so that part of the flexible connecting member 43 on the rotating shaft 45 is released, under the action of the gravity of the photovoltaic panel 20 itself, the end of the photovoltaic panel 20 connected to the flexible connecting member 43 rotates toward the side away from the mounting bracket 10, and under the action of the flexible connecting member 43, the first rotating member 44 rotates counterclockwise, and the second rotating member 47 rotates clockwise.

[0067] Therefore, the setting of the second rotating member 47 makes the rotating assembly 40 more precise, so that when the end of the photovoltaic panel 20 connected to the flexible connector 43 rotates toward or away from the side where the mounting bracket 10 is located, the flexible connector 43 can be in a tensioned state, which is more conducive to the transmission of force and improves the stability and reliability of the photovoltaic panel 20 during rotation.

[0068] According to some embodiments of the present invention, Figure 1 and Figure 4 As shown, the photovoltaic panel 20 includes a fixing portion 24 , and the other end of the flexible connector 43 is connected to the fixing portion 24 .

[0069] The fixing portion 24 is disposed at one end of the photovoltaic panel 20 along the width direction C of the photovoltaic panel 20 , and is located in the middle of the photovoltaic panel 20 along the length direction B of the photovoltaic assembly 100 . The other end of the flexible connector 43 is suitable for being fixedly connected to the fixing portion 24 .

[0070] Therefore, the provision of the fixing portion 24 facilitates the flexible connector 43 to be stably and firmly connected to the photovoltaic panel 20 , thereby ensuring the reliability of power transmission and the accuracy of position adjustment of the photovoltaic panel 20 .

[0071] According to some embodiments of the present invention, Figure 1 and Figure 5 As shown, it also includes: a sensor 25 , which is arranged on the photovoltaic panel 20 , and the sensor 25 communicates with the rotating component 40 .

[0072] The sensor 25 is used to detect sunlight. When the sensor 25 detects that the angle of sunlight changes, the sensor 25 transmits information to the control system of the rotating component 40. The drive system controls the movement of the second drive member 41 to adjust the rotation angle of the photovoltaic panel 20, so that the photovoltaic panel 20 can automatically adjust to the optimal angle to maximize the reception of solar energy, thereby realizing automatic tracking of the photovoltaic system around the clock.

[0073] Therefore, the setting of the sensor 25 and the communication between the sensor 25 and the rotating component 40 help to improve the intelligence level of the photovoltaic system, so that the photovoltaic panel 20 is always in the best sun collection position, which is beneficial for the photovoltaic panel 20 to more effectively absorb and convert solar energy, thereby improving its power generation efficiency. The rotation can prevent the photovoltaic panel 20 from direct sunlight, and help reduce the heat of the photovoltaic panel 20, thereby extending its service life.

Along the height direction A of the photovoltaic assembly 100, the projection of the mounting column 12 is located within the projection of the mounting seat 11.

[0076] Therefore, the mounting seat 11 serves as the base part of the mounting bracket 10, and the mounting seat 11 is mainly responsible for providing stable ground support to ensure the stability of the entire photovoltaic assembly 100. Through the pivotal connection between the mounting column 12 and the photovoltaic panel 20, the photovoltaic assembly 100 can adjust its angle according to the movement trajectory of the sun, significantly improving the sunlight receiving efficiency of the photovoltaic panel 20. The mounting column 12 is easy to install and maintain, and is convenient for adjusting the angle of the photovoltaic panel 20, easy to replace damaged parts, etc. It can also adapt to different installation environments, and can improve the overall reliability of the photovoltaic assembly 100.
