Description

Technical Field

[0001] This utility model relates to the field of photovoltaic mounting frame technology, and in particular to a photovoltaic module mounting frame with efficient heat dissipation function. Background Technology

[0002] With the continuous improvement of photovoltaic technology, the power density of high-efficiency photovoltaic modules has been increasing, resulting in a significant increase in the heat generated during operation. If the heat cannot be dissipated in time, it will cause the module temperature to become too high, which will not only reduce power generation efficiency but also accelerate the aging of internal materials, shorten the service life, and significantly increase the operation and maintenance costs and power generation losses of the photovoltaic system.

[0003] Existing photovoltaic (PV) module mounting racks generally suffer from inadequate heat dissipation design. Traditional racks serve only as load-bearing structures, lacking active heat dissipation guidance and relying on natural ventilation for heat dissipation, resulting in extremely low efficiency. In high-temperature environments and scenarios with densely packed modules, heat easily accumulates around the PV modules, forming localized high-temperature areas that severely impact module performance and lifespan. While some improved mounting racks attempt to incorporate heat dissipation structures, they are mostly simple opening designs that fail to create effective airflow paths. Furthermore, the location of the ventilation holes is mismatched with the heat-generating areas of the modules, leading to poor heat dissipation and failing to meet the heat dissipation requirements of high-efficiency PV modules. Therefore, this paper proposes a PV module mounting rack with highly efficient heat dissipation capabilities to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional mounting frames lack professional heat dissipation structures, leading to heat accumulation and excessively high temperatures in photovoltaic modules, resulting in a significant decrease in power generation efficiency and accelerated aging of the modules. Therefore, this invention proposes a photovoltaic module mounting frame with efficient heat dissipation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic module mounting bracket with high-efficiency heat dissipation function, including a base, a bracket fixedly connected to the surface of the base, two fixed frames fixedly connected to the surface of the bracket, a U-shaped air cavity slidably connected to the inner surface of the two fixed frames, and a plurality of heat dissipation holes opened on the surface of the U-shaped air cavity.

[0006] The aforementioned components achieve the following effects: the U-shaped air cavity and the heat dissipation holes form a dedicated heat dissipation channel. When air flows through the U-shaped air cavity, it forms convection with the surface of the photovoltaic module through the heat dissipation holes, quickly carrying away the heat generated by the module's operation, effectively reducing the module's operating temperature, ensuring that it operates within the temperature range for high-efficiency power generation, improving power generation efficiency and extending the module's service life. This avoids the situation where traditional mounting brackets lack a professional heat dissipation structure, leading to heat accumulation and excessively high temperatures in the photovoltaic modules, which in turn causes a significant decrease in power generation efficiency and accelerated aging of the modules.

[0007] Preferably, air guide plates are fixedly connected to both sides of the bracket.

[0008] The effect achieved by the above components is to avoid fluctuations in heat dissipation efficiency caused by disordered natural wind flow by actively guiding the airflow path, and to ensure stable heat dissipation, especially in low wind speed environments.

[0009] Preferably, a number of heat dissipation fins are fixedly connected to the inner surface of the U-shaped air cavity.

[0010] The effects achieved by the above components are as follows: the heat dissipation fins increase the heat dissipation area inside the U-shaped air cavity. When air flows through the air cavity, the fins can quickly absorb the heat transferred by the photovoltaic module through the heat dissipation holes and dissipate the heat into the air through heat conduction and convection. The dense arrangement of the fins forms a multi-channel heat dissipation structure, which improves the heat conduction efficiency, reduces the heat accumulation in the air cavity, and further reduces the module temperature.

[0011] Preferably, the surface of the bracket is fixedly connected to two fixing blocks, and a lead screw is threaded into the fixing blocks. The surface of the U-shaped air cavity is provided with a threaded groove, and the lead screw is threadedly connected to the inner wall of the threaded groove.

[0012] The effects achieved by the above components are as follows: the rotating screw can drive the U-shaped air cavity to slide along the fixed frame, accurately adjust the relative position of the air cavity and the photovoltaic module, adapt to modules of different sizes and arrangements, and the self-locking characteristics of the threaded connection ensure that the air cavity will not shift due to vibration after it is fixed, so that the heat dissipation holes are always aligned with the heat dissipation area of ​​the module, avoiding the heat dissipation dead angle problem caused by position deviation in traditional fixed heat dissipation structures, and improving the versatility and heat dissipation targeting of the mounting frame.

[0013] Preferably, one end of the lead screw is fixedly connected to a handle, and the arc surface of the handle is provided with a plurality of anti-slip grooves.

[0014] The effects achieved by the above components are as follows: the handle provides a point of force for the operator, the anti-slip groove increases the friction between the hand and the handle, making it easier and more precise to adjust the position of the U-shaped air cavity by rotating the screw, avoiding adjustment errors caused by slippage, and the convenient manual adjustment design can be quickly adapted to different photovoltaic module layouts on site, improving installation and maintenance efficiency.

[0015] Preferably, the surface of the bracket is provided with a plurality of mounting grooves, and a plurality of thermally conductive silicone pads are fixedly connected to the inner wall of the mounting grooves.

[0016] The effect achieved by the above components is as follows: the thermally conductive silicone pad fills the contact gap between the photovoltaic module and the bracket, and the heat at the bottom of the module is quickly conducted to the bracket through its high thermal conductivity. The bracket structure then assists in heat dissipation. At the same time, the elasticity of the silicone pad can buffer the hard contact between the module and the bracket, avoiding damage to the module caused by vibration. This achieves the dual function of "thermal conduction and buffering", improving heat dissipation efficiency and module protection.

[0017] Preferably, the air guide plate is inclined.

[0018] The effects achieved by the above components are as follows: the inclined air guide plate can optimize the airflow introduction angle, reduce wind resistance by using the principle of fluid mechanics, and allow air to enter the U-shaped air cavity more smoothly. Compared with the vertical air guide plate, the inclined design can increase the air intake of the air cavity at the same wind speed, while guiding the airflow to be evenly distributed to the heat dissipation holes, avoiding local airflow dead corners, and further enhancing the convective heat dissipation effect between the heat dissipation holes and the component surface.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, the U-shaped air cavity and the heat dissipation holes form a dedicated heat dissipation channel. When air flows through the U-shaped air cavity, it forms convection with the surface of the photovoltaic module through the heat dissipation holes, which quickly removes the heat generated by the module during operation, effectively reducing the operating temperature of the module, ensuring that it operates within the temperature range of high-efficiency power generation, improving power generation efficiency and extending the service life of the module. This avoids the situation where traditional mounting brackets lack a professional heat dissipation structure, resulting in heat accumulation and excessively high temperature of the photovoltaic module, which in turn causes a significant decrease in power generation efficiency and accelerated aging of the module.

[0026] Reference Figure 1-4As shown, this utility model provides a technical solution: a photovoltaic module mounting bracket with high-efficiency heat dissipation function, including a base 1, a support 2 fixedly connected to the surface of the base 1, two fixed brackets 3 fixedly connected to the surface of the support 2, and a U-shaped air cavity 4 slidably connected to the inner surface of the two fixed brackets 3. The surface of the U-shaped air cavity 4 is provided with several heat dissipation holes 5. Air guide plates 6 are fixedly connected to both sides of the support 2. By actively guiding the airflow path, the heat dissipation efficiency fluctuation caused by disordered natural wind flow is avoided, ensuring stable heat dissipation, especially in low wind speed environments. Several heat dissipation fins 7 are fixedly connected to the inner surface of the U-shaped air cavity 4. The heat dissipation fins 7 increase the heat dissipation area inside the U-shaped air cavity. When air flows through the air cavity, the fins can quickly... The heat dissipation system rapidly absorbs the heat transferred from the photovoltaic module through the heat dissipation holes 5 and dissipates it into the air through heat conduction and convection. The dense arrangement of the fins forms a multi-channel heat dissipation structure, improving heat conduction efficiency, reducing heat accumulation in the air cavity, and further reducing the module temperature. Two fixing blocks 8 are fixedly connected to the surface of the bracket 2. A screw 9 is threaded into the fixing block 8. The surface of the U-shaped air cavity 4 has a threaded groove 11. The screw 9 is threaded to the inner wall of the threaded groove 11. Rotating the screw 9 can drive the U-shaped air cavity to slide along the fixing frame 3, precisely adjusting the relative position of the air cavity and the photovoltaic module to adapt to modules of different sizes and arrangements. The self-locking characteristic of the threaded connection ensures that the air cavity will not shift due to vibration after it is fixed, so that the heat dissipation holes 5 are always aligned with the heat-generating area of ​​the module. To avoid the heat dissipation dead angle problem caused by positional deviation in traditional fixed heat dissipation structures, the mounting bracket is improved in terms of versatility and targeted heat dissipation. One end of the lead screw 9 is fixedly connected to a handle 10. The arc surface of the handle 10 has several anti-slip grooves, providing a force point for the operator. The anti-slip grooves increase the friction between the hand and the handle 10, making it easier and more precise to rotate the lead screw 9 to adjust the position of the U-shaped air cavity, avoiding adjustment errors caused by slippage. The convenient manual adjustment design can be quickly adapted to different photovoltaic module layouts on site, improving installation and maintenance efficiency. The surface of the bracket 2 has several mounting grooves 12, and the inner wall of the mounting grooves 12 is fixedly connected to several thermally conductive silicone pads 13. The thermally conductive silicone pads 13 fill the gap between the photovoltaic module and the bracket. The contact gap of the bracket 2 allows for rapid heat transfer from the bottom of the component to the bracket 2 through high thermal conductivity. The structure of the bracket 2 then assists in heat dissipation. At the same time, the elasticity of the silicone pad can buffer the hard contact between the component and the bracket 2, avoiding damage to the component caused by vibration. This achieves the dual function of "thermal conduction and buffering", improving heat dissipation efficiency and component protection. The air guide plate 6 is tilted. The tilted air guide plate 6 can optimize the airflow introduction angle and reduce wind resistance using fluid dynamics principles, allowing air to enter the U-shaped air cavity more smoothly. Compared with the vertical air guide plate 6, the tilted design can increase the air intake of the air cavity at the same wind speed, while guiding the airflow to be evenly distributed to the heat dissipation holes 5, avoiding local airflow dead zones, and further enhancing the convective heat dissipation effect between the heat dissipation holes 5 and the component surface.

[0027] Working principle: The U-shaped air cavity is slidably connected to the support 2 via the fixed frame 3. Its surface heat dissipation holes 5 form a convection channel with the photovoltaic module surface. When air flows through the U-shaped air cavity, heat is transferred from the module surface to the interior of the air cavity through the heat dissipation holes 5. The airflow carries the heat away, achieving active heat dissipation for the module. The U-shaped structure of the air cavity increases the heat dissipation path length, prolongs the heat exchange time, and improves heat dissipation efficiency. The heat dissipation fins 7 on the inner surface of the U-shaped air cavity increase the heat dissipation area, quickly absorbing the heat transferred from the module through heat conduction. When air flows through the gaps between the fins, it dissipates the heat through convection. The heat dissipates to the outside, and the densely arranged fins form a multi-channel heat dissipation structure, reducing heat accumulation in the air cavity and further reducing the component temperature. The thermally conductive silicone pad 13 in the mounting slot 12 of the bracket 2 fills the gap between the component and the bracket 2, and uses its high thermal conductivity to conduct the heat from the bottom of the component to the metal structure of the bracket 2. Through the heat dissipation of the bracket 2 itself and heat exchange with the air, the component temperature is reduced. At the same time, the elasticity of the silicone pad buffers the vibration of the component and avoids damage from hard contact. The inclined air guide plates 6 on both sides of the bracket 2 use the principle of fluid mechanics to guide the natural wind into the U-shaped airflow at an optimized angle. The inclined design of the cavity reduces wind resistance, increases the air intake volume, and ensures even airflow distribution to the heat dissipation holes 5, avoiding localized dead air zones. In low-wind-speed environments, the air guide plate 6 can increase the airflow velocity inside the cavity, ensuring stable heat dissipation. The air guide plate 6 guides the airflow into the U-shaped cavity, and after heat exchange with the component surface through the heat dissipation holes 5, it is discharged through the other end of the cavity, forming a complete airflow cycle of "introduction-heat exchange-exhaust". The heat dissipation fins 7 further agitate the airflow, enhance turbulence, improve heat exchange efficiency, and ensure rapid heat dissipation. The screw 9 on the rotating fixing block 8... The U-shaped air cavity is driven by the threaded drive to slide along the fixed frame 3, precisely adjusting the relative position of the air cavity and the component. Operators can align the heat dissipation hole 5 with the heat-generating area according to the component size and layout, avoiding the heat dissipation dead corners of traditional fixed structures. The self-locking characteristic of the threaded connection ensures that the air cavity will not shift due to vibration after it is fixed, ensuring targeted heat dissipation. The handle 10 with anti-slip groove at the end of the screw 9 is the force application point. The anti-slip design increases the operating friction, making the adjustment process labor-saving and precise. It can be quickly adapted to different component layouts on site, and the air cavity position can be adjusted without tools, improving installation and maintenance efficiency.
