Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell module heat dissipation technology, specifically to a photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices. Background Technology

[0002] A photovoltaic (PV) module refers to the smallest indivisible assembly of photovoltaic cells that is encapsulated and internally connected, capable of independently providing direct current (DC) output. Its function is to convert solar energy into electrical energy with the assistance of an inverter, and then store it in batteries for use with subsequent loads.

[0003] Currently, existing photovoltaic (PV) module structures suffer from low heat dissipation efficiency due to high ambient temperatures, reducing the conversion efficiency of PV cells. To address this, a wind-cooled heat dissipation device is typically installed externally to the PV module. This device is used to dissipate heat during or after PV module operation. However, the temperature of the PV cells varies depending on the external environment. For example, when the ambient temperature is low or the wind is strong, the heat dissipation efficiency of the PV cells is relatively high, and the heat dissipation device may not be needed during these times. To save energy, we propose a PV module structure that facilitates the installation of a heat dissipation and cooling device. Summary of the Invention

[0004] The main objective of this invention is to provide a photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a photovoltaic cell module structure for easy installation of heat dissipation and cooling devices, comprising a fixed frame, wherein a photovoltaic module is fixedly installed in the inner wall of the fixed frame, and a protective shell is detachably connected to the outer wall of the fixed frame. A heat dissipation component is disposed within the protective shell, and a limiting device and an opening / closing device are fixedly connected to the outer wall of the protective shell. The limiting device includes:

[0006] A positioning post is fixedly connected to the outer wall of the protective shell. The positioning post is penetrated by a rotating rod and rotatably connected to the rotating rod. The rotating rod penetrates a damping ring and is rotatably connected to the damping ring.

[0007] An elliptical block is fixedly connected to the bottom of the rotating rod. A fixing plate is fixedly connected to the inner wall of the positioning post, and a sliding plate is slidably connected to the inner wall of the positioning post.

[0008] and a sealing assembly, wherein the sealing assembly is disposed in the positioning post.

[0009] Preferably, the slide plate is elastically connected to the inner wall of the positioning post by a return spring. A protrusion is fixedly connected to the side of the slide plate near the inner wall of the positioning post. By using the return spring, the slide plate can be reset after being compressed and slid.

[0010] Preferably, the photovoltaic module includes photovoltaic glass, solar cells, and heat dissipation fins. The side of the solar cell away from the photovoltaic glass is fixedly connected to the heat dissipation fins. The heat dissipation fins can absorb the heat dissipation of the solar cell and dissipate the heat.

[0011] Preferably, the outer wall of the fixing frame is provided with a groove and a positioning port, and the inner wall of the fixing frame is provided with an inner groove. A guide plate is slidably connected in the inner groove. The guide plate and the inner groove are elastically connected by a compression spring. A wedge block is fixedly connected to the side of the guide plate away from the compression spring. The compression spring can compress the guide plate, so that the wedge block can fix the positioning post, which facilitates the quick installation of the positioning post.

[0012] Preferably, the positioning post has an opening on the side near the wedge block, and the size of the opening matches that of the wedge block.

[0013] Preferably, the sealing assembly includes an air chamber, which is fixedly connected to the outer wall of the fixing plate. A piston is connected to the inner wall of the air chamber. The lower end of the air chamber is connected to the air cushion through an air pipe, and the upper end of the air chamber is connected to the sealing ring through an air pipe. By squeezing the air cushion with a wedge block, gas can be delivered to the sealing ring through the air pipe, causing the sealing ring to expand and improve the sealing performance after the positioning post is installed, preventing moisture from entering the inner groove and corroding the wedge block and other parts.

[0014] Preferably, a motor is fixedly connected to the outer wall of the protective shell, and an oblique opening is provided on the outer wall of the protective shell for exhausting air.

[0015] Preferably, the heat dissipation assembly includes a rotating shaft rotatably connected to the inner wall of the protective shell. The rotating shaft is fixedly connected to the output shaft of the motor. The rotating shaft passes through the sleeve and is fixedly connected to the sleeve. Blades are fixedly connected to the outer wall of the sleeve. A fixing rod is fixedly connected to the outer wall of the rotating shaft. A positioning rod is fixedly connected to the inner wall of the protective shell. An inclined rod is rotatably connected to the positioning rod. A guide plate is hinged to the end of the inclined rod away from the rotating shaft. By rotating the rotating shaft, the blades can be driven to rotate and output wind power. At the same time, the fixing rod can drive the inclined rod to swing, thereby adjusting the guide plate to adjust the angle of wind power delivery and achieve uniform heat dissipation of the heat dissipation fins.

[0016] Preferably, the opening and closing device includes a fixed chamber, an expansion airbag is embedded inside the fixed chamber, a movable plate is slidably connected to the inner wall of the fixed chamber, and a heat-conducting sheet is fixedly connected to the outer wall of the fixed chamber. By using the expansion airbag, when the temperature of the battery cell is high, the heat-conducting sheet can transfer heat, causing the expansion airbag to expand, which facilitates the subsequent start-up of the motor.

[0017] Preferably, a sleeve rod is fixedly connected to the side of the movable plate away from the inflatable airbag, the sleeve rod is sleeved with a T-rod, and the inner wall of the sleeve rod is elastically connected to the T-rod by a connecting spring. An elastic telescopic rod is fixedly connected to the outer wall of the T-rod, an electrode plate is fixedly connected to the top of the T-rod, and a metal plate is fixedly connected to the inner wall of the fixed chamber.

[0018] Beneficial effects

[0019] This invention provides a photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices. It offers the following advantages:

[0020] (1) The photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices uses an opening and closing device and a heat dissipation component. After the protective shell is installed, it can transfer heat to the fixed chamber through the heat-conducting plate. Under the expansion of the expansion airbag, it can drive the moving plate to raise the sleeve rod. Under the limiting action of the elastic telescopic rod, the T rod compresses the connecting spring. Only after the sleeve rod continues to rise and squeezes the telescopic end of the elastic telescopic rod to release the limit, the T rod resets under the action of the connecting spring, so that the electrode plate contacts the metal plate, and the motor switch is turned on, so that the heat dissipation component works to dissipate heat from the cell. During the contraction of the expansion airbag, the sleeve rod resets, and the connecting spring continues to reset. Under the action of the connecting spring, the electrode plate of the T rod will continue to contact the metal plate. After cooling for a period of time, the electrode plate will separate from the metal plate. The motor will not be continuously turned on and off in a short period of time, saving energy.

[0021] (2) The photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices uses heat dissipation components to make the fixed rod rotate when the blades are rotating to transport wind power, so that the inclined rod swings and the guide plate is adjusted to adjust the angle when the wind power is transported, thereby achieving uniform heat dissipation of the heat dissipation fins and improving the heat dissipation effect.

[0022] (3) The photovoltaic cell module structure that facilitates the installation of heat dissipation and cooling devices uses a limiting device to allow the positioning post to be quickly inserted into the positioning port after being aligned with it, thereby achieving rapid installation and fixation of the heat dissipation module and the opening and closing device. At the same time, the wedge block squeezes the air cushion, which allows the gas vent pipe to deliver gas to the sealing ring, causing the sealing ring to expand and improve the sealing performance after the positioning post is installed, preventing water vapor from entering the inner groove and corroding the wedge block and other parts, thus achieving a protective effect.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-8This invention proposes a photovoltaic cell module structure that facilitates the installation of a heat dissipation and cooling device. The structure includes a fixed frame 1, with a photovoltaic module 2 fixedly installed on the inner wall of the fixed frame 1. The photovoltaic module 2 includes photovoltaic glass 21, solar cells 22, and heat dissipation fins 23. The side of the solar cell 22 furthest from the photovoltaic glass 21 is fixedly connected to the heat dissipation fins 23. The heat dissipation fins 23 absorb heat from the solar cell 22, facilitating heat dissipation. A protective shell 3 is detachably connected to the outer wall of the fixed frame 1 to protect the heat dissipation component 4. The heat dissipation component 4 is housed within the protective shell 3. A limiting device 5 and an opening / closing device 6 are fixedly connected to the outer wall of the protective shell 3. The limiting device 5 allows for quick installation and fixation of the protective shell 3, while the opening / closing device 6 controls the temperature of the solar cell 22. The heat dissipation component 4 can be activated to dissipate heat when the temperature is high, and the heat dissipation component 4 can be activated to shut down when the temperature of the battery cell 22 is low. The limiting device 5 includes a positioning post 51, which is fixedly connected to the outer wall of the protective shell 3. The positioning post 51 is penetrated by a rotating rod 52 and is rotatably connected to the rotating rod 52. The rotating rod 52 penetrates a damping ring 53 and is rotatably connected to the damping ring 53. The rotation of the rotating rod 52 can be damped by the use of the damping ring 53. An elliptical block 54 is fixedly connected to the bottom of the rotating rod 52. A fixing plate 55 is fixedly connected to the inner wall of the positioning post 51. A sliding plate 56 is slidably connected to the inner wall of the positioning post 51. A sealing component 58 is provided in the positioning post 51. The sealing component 58 can seal the positioning post 51 during installation to prevent moisture in the air from entering.

[0037] In an embodiment of the present invention, in order to enable the heat dissipation assembly 4 to be installed quickly, specifically, the inner wall of the sliding plate 56 and the positioning post 51 are elastically connected by a return spring. A protrusion 57 is fixedly connected to the side of the sliding plate 56 near the inner wall of the positioning post 51. A groove 101 and a positioning opening 102 are provided on the outer wall of the fixing frame 1. An inner groove 103 is provided in the inner wall of the fixing frame 1. A guide plate 104 is slidably connected in the inner groove 103. The guide plate 104 and the inner groove 103 are elastically connected by a compression spring. The side of the guide plate 104 away from the compression spring is fixedly connected to... A wedge block 105 is attached. The positioning post 51 has an opening on the side near the wedge block 105, and the size of the opening matches the wedge block 105. By aligning the positioning post 51 with the positioning opening 102 and inserting the positioning post 51 into the positioning opening 102, the wedge block 105 is squeezed, causing the guide plate 104 to squeeze the compression spring. After the opening of the positioning post 51 is aligned with the wedge block 105, the wedge block 105 can be inserted into the opening under the action of the compression spring, thus fixing the positioning post 51 and realizing the rapid installation of the protective shell 3 and the heat dissipation assembly 4.

[0038] Furthermore, in order to protect the parts in the inner groove 103 and extend their service life, the sealing assembly 58 specifically includes an air chamber 581, which is fixedly connected to the outer wall of the fixing plate 55. A piston 582 is connected to the inner wall of the air chamber 581. The lower end of the air chamber 581 is connected to the air cushion 583 through an air pipe, and the upper end of the air chamber 581 is connected to the sealing ring 584 through an air pipe. By squeezing the air cushion 583 by the wedge block 105, the gas can be delivered to the sealing ring 584 through the gas vent pipe, causing the sealing ring 584 to expand and improve the sealing performance of the positioning post 51 after installation, preventing moisture from entering the inner groove 103 and corroding the wedge block 105 and other parts.

[0039] In an embodiment of the present invention, in order to achieve uniform heat dissipation of the heat dissipation fins 23, specifically, a motor 31 is fixedly connected to the outer wall of the protective shell 3, and an oblique opening 32 is provided on the outer wall of the protective shell 3 for exhausting cooling air. The heat dissipation assembly 4 includes a rotating shaft 41, which is rotatably connected to the inner wall of the protective shell 3. The rotating shaft 41 is fixedly connected to the output shaft of the motor 31, and the rotating shaft 41 passes through and is fixedly connected to the sleeve 42. Blades 43 are fixedly connected to the outer wall of the sleeve 42, and a fixed blade is fixedly connected to the outer wall of the rotating shaft 41. A positioning rod 45 is fixedly connected to the inner wall of the protective shell 3 to support the inclined rod 46. The positioning rod 45 is rotatably connected to the inclined rod 46. The end of the inclined rod 46 away from the rotating shaft 41 is hinged to a guide plate 47. The output shaft of the motor 31 rotates, which drives the rotating shaft 41 to rotate, thereby driving the sleeve 42 to rotate, causing the blades 43 to rotate and output wind power. At the same time, the fixed rod 44 can drive the inclined rod 46 to swing, thereby adjusting the guide plate 47 to adjust the angle of wind power delivery and achieve uniform heat dissipation of the heat dissipation fins 23.

[0040] Furthermore, in order to save energy and improve the performance of the heat dissipation component 4, the opening and closing device 6 specifically includes a fixed chamber 61, inside which is embedded an expansion airbag 62 filled with carbon dioxide gas. The expansion airbag 62 expands when heated and contracts when cooled. A movable plate 63 is slidably connected to the inner wall of the fixed chamber 61, and a heat-conducting plate 64 is fixedly connected to the outer wall of the fixed chamber 61 for heat transfer. A sleeve rod 65 is fixedly connected to the side of the movable plate 63 away from the expansion airbag 62. A T-rod 66 is sleeved on the sleeve rod 65, and the inner wall of the sleeve rod 65 is elastically connected to the T-rod 66 by a connecting spring. An elastic telescopic rod 67 is fixedly connected to the outer wall of the T-rod 66. The telescopic end of the elastic telescopic rod 67 is wedge-shaped. An electrode plate 68 is fixedly connected to the top of the T-rod 66. A metal plate 69 is fixedly connected to the inner wall of the fixed chamber 61. The heat generated by the battery cell 22 is transferred to the fixed chamber 61 through the heat-conducting plate 64. In the fixed position 61, the expansion of the air bladder 62 drives the moving plate 63, causing the sleeve rod 65 to rise. Under the limiting effect of the telescopic end of the elastic telescopic rod 67, the T rod 66 compresses the connecting spring. Only when the sleeve rod 65 continues to rise and compress the elastic telescopic rod 67, releasing the limiting effect of the telescopic end of the elastic telescopic rod 67, will the T rod 66 return to its original position under the action of the connecting spring. This will cause the electrode plate 68 to contact the metal plate 69, connecting the switch of the motor 31 and enabling the heat dissipation component 4 to work and dissipate heat from the battery cell 22. After the battery cell 22 cools down due to heat dissipation, the air bladder 62 contracts, the sleeve rod 65 returns to its original position, and the connecting spring continues to return to its original position. Under the force of the connecting spring, the electrode plate 68 and the metal plate 69 of the T rod 66 will continue to contact each other. After cooling down for a period of time, the electrode plate 68 will detach from the metal plate 69, achieving the effect of not continuously turning the motor 31 on and off in a short period of time, while saving energy.

[0041] In this invention, during use, the positioning post 51 is first aligned with the positioning port 102, and then the positioning post 51 is inserted into the positioning port 102. This then compresses the wedge block 105, causing the guide plate 104 to compress the compression spring. After the opening of the positioning post 51 is aligned with the wedge block 105, the wedge block 105 can be inserted into the opening under the action of the compression spring, thus fixing the positioning post 51 and completing the installation of the protective shell 3. At the same time, the wedge block 105 compresses the air cushion 583, which allows the gas vent pipe to deliver gas to the sealing ring 584, causing the sealing ring 584 to expand and improve the sealing performance of the positioning post 51 after installation.

[0042] Meanwhile, as the working temperature of the battery cell 22 rises, the heat-conducting plate 64 transfers the heat generated by the battery cell 22 to the fixed chamber 61. Under the expansion of the expansion bladder 62, it can drive the moving plate 63 to rise, causing the sleeve rod 65 to rise. Under the limiting effect of the extension end of the elastic telescopic rod 67, the T rod 66 compresses the connecting spring. Only when the sleeve rod 65 continues to rise and squeezes the elastic telescopic rod 67, causing the extension end of the elastic telescopic rod 67 to be compressed and released from the limiting, the T rod 66 returns to its original position under the action of the connecting spring, so that the electrode plate 68 contacts the metal plate 69, and the switch of the motor 31 is turned on, so that the heat dissipation component 4 works to dissipate heat from the battery cell 22. During this process, the output shaft of the motor 31 rotates, driving the rotating shaft 41 to rotate, which in turn drives the sleeve 42 to rotate, causing the blades 43 to rotate and output wind power. At the same time, the fixed rod 44 can drive the inclined rod 46 to swing, which in turn adjusts the guide plate 47, causing the airflow to swing, thus completing the uniform heat dissipation of the heat dissipation fins 23.

[0043] Meanwhile, after the heat dissipation temperature of the battery cell 22 decreases, the expansion bladder 62 contracts, the sleeve rod 65 resets, and the connecting spring continues to reset. Under the force of the connecting spring, the electrode plate 68 of the T rod 66 remains in contact with the metal plate 69. After cooling for a period of time, the electrode plate 68 will detach from the metal plate 69, and the motor 31 will be turned off.

[0044] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
