Description

Technical Field

[0001] This utility model relates to the field of photovoltaic structure technology, specifically a photovoltaic panel backplate structure with heat dissipation channels. Background Technology

[0002] The photovoltaic backsheet is a key encapsulation material on the back of a photovoltaic module, located on the outermost layer. Its main functions include protecting the cells from humid and hot environments, providing insulation support, and reducing module temperature through its high infrared reflectivity. However, the existing photovoltaic panel backsheet structure cannot effectively assist in the heat dissipation of the photovoltaic panel during use, resulting in poor heat dissipation performance and low practicality.

[0003] To address the aforementioned issues, this application proposes a photovoltaic panel backsheet structure with heat dissipation channels to solve these problems. Utility Model Content

[0004] In order to solve the problem that existing photovoltaic panel backsheet structures cannot effectively assist in the heat dissipation of photovoltaic panels during use, the purpose of this utility model is to provide a photovoltaic panel backsheet structure with heat dissipation channels.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a photovoltaic panel backsheet structure with heat dissipation channels, including a backsheet body, an array of heat dissipation channel bodies opened on the backsheet body, and a heat dissipation mechanism that works in conjunction with the heat dissipation channel bodies at one end of the backsheet body, and a docking mechanism that works in conjunction with the heat dissipation mechanism. The heat dissipation mechanism includes a distribution frame, which is fixedly connected to the back plate body and connected to one end of the heat dissipation channel body. A connecting frame is detachably sleeved on the distribution frame, and a collecting frame is fixedly connected to one end of the connecting frame. A grid plate is integrally formed in the inner cavity of the collecting frame, and a fan is fixedly inserted in the middle of the grid plate. A locking hole is opened through the middle of the grid plate, and the fan is fixedly inserted in the locking hole. A connecting groove and a recessed groove are opened through the lower end of the collecting frame, and a filter plate is detachably inserted in the recessed groove. A groove is opened at the bottom of the collecting frame to cooperate with the recessed groove, and the groove has a symmetrical structure. A countersunk hole is opened at the bottom of the collecting frame, and a rotating shaft is rotatably inserted in the countersunk hole. A rotating hole is opened in the countersunk hole, and the rotating shaft is rotatably inserted in the rotating hole. A stop rod is fixedly sleeved at the end of the rotating shaft, and the stop rod can slide and fit against the filter plate. A torsion spring is fixedly installed at one end of the stop rod, and the end of the torsion spring is fixedly connected to the inner wall of the countersunk hole.

[0006] Preferably, the docking mechanism includes a plug rod that is slidably inserted into the socket frame and has a symmetrical structure. The lower end of the socket frame has symmetrically arranged sliding holes through which the plug rod is slidably inserted. A pull plate is fixedly connected to the bottom end of the plug rod, and a spring is fixedly installed on one side of the pull plate. The end of the spring is fixedly connected to the socket frame. A handle is fixedly connected to the pull plate and is symmetrically distributed. The bottom end of the diverter frame has symmetrically arranged insertion holes, and the plug rod can be slidably inserted into the insertion holes. The outer diameter of the end of the plug rod is the same as the inner diameter of the insertion hole.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using the heat dissipation mechanism in conjunction with the heat dissipation channel body, the heat dissipation channel body can dissipate heat on its own when the ambient temperature of the photovoltaic panel is suitable, and can use filtered cold air to assist in heat dissipation when the ambient temperature of the photovoltaic panel is high. This effectively improves the practicality of the back panel structure and the heat dissipation effect of the photovoltaic panel, and realizes the convenient disassembly and assembly of the filter plate, thereby effectively reducing the rate at which dust adheres to the heat dissipation channel body. 2. The docking mechanism facilitates the insertion and separation of the plug and the socket, thereby making it easier for the socket frame and the diverter frame to be fixed and disassembled, which is convenient for users to operate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figures 1-5 As shown, this utility model provides a photovoltaic panel backsheet structure with heat dissipation channels, including a backsheet body 1, an array of heat dissipation channel bodies 11 on the backsheet body 1, and a heat dissipation mechanism 2 that works in conjunction with the heat dissipation channel bodies 11 at one end of the backsheet body 1, and a docking mechanism 3 that works in conjunction with the heat dissipation mechanism 2. The heat dissipation mechanism 2 includes a diversion frame 21, which is fixedly connected to the backplate body 1 and connected to one end of the heat dissipation channel body 11. A connecting frame 22 is detachably sleeved on the diversion frame 21, and a collecting frame 23 is fixedly connected to one end of the connecting frame 22. A grid plate 24 is integrally formed in the inner cavity of the collecting frame 23, and a fan 25 is fixedly inserted into the middle of the grid plate 24. A through hole 215 is provided in the middle of the grid plate 24, and the fan 25 is fixedly inserted into the through hole 215. The setting of the through hole 215 provides a guarantee for the stable installation of the fan 25. The fan 25 is controlled by a PLC control module and a temperature control module, so that the fan 25 can be started and stopped according to the real-time temperature of the photovoltaic panel. This is existing technology and will not be described in detail here. A through hole is provided at the lower end of the collecting frame 23. The connecting groove 26 and the settling groove 27 are used together, and the filter plate 28 is detachably inserted into the settling groove 27. The bottom end of the air collecting frame 23 is provided with a groove 216 that is used in conjunction with the settling groove 27. The groove 216 has a symmetrical structure. The setting of the groove 216 provides convenience for the disassembly and assembly of the filter plate 28. The bottom end of the air collecting frame 23 is provided with a countersunk hole 29. A rotating shaft 210 is rotatably inserted into the countersunk hole 29. A rotating hole 217 is provided in the countersunk hole 29. The rotating shaft 210 is rotatably inserted into the rotating hole 217. The setting of the rotating hole 217 provides a guarantee for the stable rotation of the rotating shaft 210. A stop rod 211 is fixedly sleeved at the end of the rotating shaft 210. The stop rod 211 can slide and fit against the filter plate 28. A torsion spring 212 is fixedly installed at one end of the stop rod 211. The end of the torsion spring 212 is fixedly connected to the inner wall of the countersunk hole 29.

[0017] By adopting the above technical solution, when in use, the baffle 211 can be pushed to rotate, thereby torsion spring 212. When the baffle 211 is completely misaligned with the sink 27, the filter plate 28 can be easily disassembled and assembled. After the disassembly and assembly are completed, the baffle 211 is released and the torsion spring 212 resets the baffle 211. In addition, during the use of the sleeve frame 22, the fan 25 can continuously draw outside cold air into the air collecting frame 23 and filter it by the filter plate 28 when it is drawn in. Then, the filtered cold air will be diverted by the sleeve frame 22 and the diversion frame 21 to the heat dissipation channel body 11 and carry away heat for heat dissipation and cooling when it flows inside.

[0018] The docking mechanism 3 includes a plug rod 31, which is slidably inserted into the socket frame 22. The plug rod 31 has a symmetrical structure. The lower end of the socket frame 22 has symmetrically arranged sliding holes 214, and the plug rod 31 is slidably inserted into the sliding holes 214. The sliding holes 214 limit and guide the movement of the plug rod 31. The bottom end of the plug rod 31 is fixedly connected to a pull plate 32, and a spring 33 is fixedly installed on one side of the pull plate 32. The end of the spring 33 is fixedly connected to the socket frame 22. The pull plate 32 is fixedly connected to a gripping rod 34, which is symmetrically distributed. The bottom end of the diversion frame 21 has symmetrically arranged insertion holes 213, and the plug rod 31 can be slidably inserted into the insertion holes 213. The outer diameter of the end of the plug rod 31 is the same as the inner diameter of the insertion hole 213, thereby ensuring the stability of the insertion of the plug rod 31 and the insertion hole 213.

[0019] By adopting the above technical solution, when in use, the user can simultaneously pull the two handles 34 to the side away from the socket frame 22, thereby simultaneously driving the two pull plates 32 to move, which in turn drives the two insertion rods 31 to move and simultaneously stretches the two springs 33. When the distance between the pull plate 32 and the socket frame 22 is moved to the maximum, the socket frame 22 can be easily separated from the diversion frame 21 or the socket frame 22 can be easily fitted onto the outside of the diversion frame 21. Then, the two handles 34 are released, at which time the springs 33 will drive the insertion rods 31 to reset or drive the insertion rods 31 to be inserted into the corresponding insertion holes 213.

[0020] Working principle: When in use, the user can simultaneously pull the two handles 34 to the side away from the socket frame 22, thereby simultaneously driving the two pull plates 32 to move, which in turn drives the two insertion rods 31 to move and simultaneously stretches the two springs 33. When the distance between the pull plate 32 and the socket frame 22 is moved to the maximum, the socket frame 22 can be easily separated from the diverter frame 21 or the socket frame 22 can be easily fitted onto the outside of the diverter frame 21. Then, the two handles 34 are released. At this time, the springs 33 will drive the insertion rods 31 to reset or drive the insertion rods 31 to be inserted into the corresponding insertion holes 213. It can also push the baffle 211 to rotate, thereby torsion spring 212. When the baffle 211 is completely misaligned with the sink 27, the filter plate 28 can be easily disassembled and assembled. After the disassembly and assembly are completed, the baffle 211 is released and the torsion spring 212 resets the baffle 211. In addition, during the use of the sleeve frame 22, the fan 25 can continuously draw outside cold air into the air collection frame 23 and filter it by the filter plate 28 when it is drawn in. Then the filtered cold air will be diverted by the sleeve frame 22 and the diversion frame 21 to the heat dissipation channel body 11 and carry away heat for heat dissipation and cooling when it flows inside.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
