Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a heat dissipation frame for a photovoltaic module. Background Technology

[0002] In photovoltaic power generation systems, photovoltaic modules are the core energy conversion devices. Their efficiency is closely related to their operating temperature. As the intensity of sunlight increases, the surface temperature of photovoltaic modules rises continuously, leading to a decrease in energy conversion efficiency and even affecting the stability and lifespan of the modules. Therefore, heat dissipation treatment is required for photovoltaic modules. Traditional photovoltaic module heat dissipation methods mostly rely on natural convection or forced air cooling. Natural convection has limited heat dissipation efficiency and may cause insufficient heat dissipation of photovoltaic modules, affecting their normal operation. At the same time, forced air cooling structures will increase the heat dissipation cost of photovoltaic modules and make it difficult to achieve energy-saving goals.

[0003] To address the aforementioned issues, a heat dissipation frame for photovoltaic modules has been developed. Utility Model Content

[0004] In order to overcome the shortcomings of traditional photovoltaic module heat dissipation methods, such as limited heat dissipation efficiency, which may lead to insufficient heat dissipation affecting the normal operation of photovoltaic modules, increasing the heat dissipation cost of photovoltaic modules, and making it difficult to achieve energy-saving goals, this utility model provides a heat dissipation frame for photovoltaic modules.

[0005] The technical solution of this utility model is as follows: a heat dissipation frame for a photovoltaic module, including two mounting frames. Connecting plates are connected between the upper and lower sides of each mounting frame. Each mounting frame has a cavity. A guide plate is connected to the lower part of each mounting frame. A heat sink is snapped between the connecting plates. The heat sink includes snap-fit ​​components. Each connecting plate has snap-fit ​​components, and fins are connected between the snap-fit ​​components. A protruding plate is connected to the lower part of each snap-fit ​​component. A thermally conductive pad is provided on the heat sink to transfer heat from the photovoltaic panel to the heat sink for heat dissipation.

[0006] As an improvement to the above solution, it also includes mounting holes, with seven mounting holes on the upper part of each mounting bracket.

[0007] As an improvement to the above solution, the front side of the mounting bracket is lower than the rear side.

[0008] As an improvement to the above scheme, the guide plates are all inclined structures that are wider on the outside and narrower on the inside.

[0009] As an improvement to the above solution, the heat sink has a detachable connection structure.

[0010] As an improvement to the above solution, all the snap-fit ​​components are capable of elastic deformation.

[0011] By adopting the above technical solutions, this utility model has the following advantages:

[0012] This invention effectively improves airflow speed through the outer wide and inner narrow structure of the guide plate and the front low and rear high property of the mounting bracket. At the same time, the thermal pad transfers heat from the photovoltaic module to the heat sink, and the fins on the heat sink can effectively increase the heat dissipation area. The two work together to significantly improve heat dissipation efficiency. Furthermore, the snap-fit ​​connection method makes cleaning or replacing the heat sink more convenient, which helps to save maintenance time and improve maintenance efficiency.

[0018] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0019] A heat dissipation frame for a photovoltaic module, such as Figures 1-4 As shown, the system includes two mounting frames 1, with the front side of each frame lower than the rear side. Connecting plates 7 connect the upper and lower sides of each mounting frame 1. Each mounting frame 1 has a cavity 2 and seven mounting holes 3 on its upper part. A guide plate 4 is connected to the lower part of each mounting frame 1. The guide plates 4 have a sloping structure that is wider on the outside and narrower on the inside. A heat sink 5 is snapped between the connecting plates 7. The heat sink 5 has a detachable connection structure and includes snap-fit ​​parts 52. Each connecting plate 7 has snap-fit ​​parts 52 that can elastically deform. Fins 51 connect between the snap-fit ​​parts 52. A protruding plate 53 is connected to the lower part of each snap-fit ​​part 52. A thermal pad 6 is provided on the heat sink 5 to transfer heat from the photovoltaic panel to the heat sink 5 for heat dissipation.

[0020] It should be noted that photovoltaic (PV) modules are the core devices for converting solar energy into electrical energy, and their performance directly affects the efficiency and reliability of the power generation system. As sunlight intensity increases, the output efficiency of PV panels decreases with rising operating temperature. Therefore, heat dissipation is necessary for PV modules. First, the PV modules are fixed to the mounting frame 1 through mounting holes 3. The cavity 2 inside the mounting frame 1 forms a vertical airflow channel. Heat from the PV modules is transferred to the heat sink 5 through the thermal pad 6. The heat sink 5 has a finned structure 51 on its surface, which significantly increases the surface area in contact with air, thereby improving heat dissipation. The overall heat dissipation efficiency is improved. At the same time, the low front and high rear properties of the mounting bracket 1, combined with the wide outer and narrow inner structure of the guide plate 4, cause the cross-sectional area of ​​the external airflow to gradually decrease as it flows through the guide plate 4, and the airflow speed increases accordingly, further enhancing the convective heat dissipation effect and significantly improving the heat dissipation performance. This design requires no additional energy consumption and has a good energy-saving effect. When it is necessary to clean or replace the radiator 5, the protruding plate 53 can be pressed down to cause the snap-fit ​​52 to elastically deform and disengage from the snap-fit ​​position on the connecting plate 7, realizing the quick disassembly of the radiator 5, which is convenient for maintenance and replacement, and improves the operability and maintenance efficiency of the system.

[0021] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
