Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel heat dissipation technology, specifically a frame structure that utilizes a photovoltaic panel frame for forced convection heat dissipation. Background Technology

[0002] Solar energy is a clean natural energy source. With technological advancements, the solar energy conversion efficiency of photovoltaic panels is gradually improving, and photovoltaic power generation is becoming increasingly popular and large-scale. However, the inherent heat generation problem of semiconductor photovoltaic materials persists, and the heat generated by the photovoltaic panels themselves also increases due to the improved conversion efficiency.

[0003] CN106533332B discloses a photovoltaic panel heat dissipation bracket, mainly comprising a main bracket pipe, a main pipe extension groove, and an exhaust pipe. The cross-sectional area of ​​the main bracket pipe is larger than that of the exhaust pipe, and the main bracket pipe and the exhaust pipe are connected as a single unit by a pyramidal tube. The main pipe extension groove is a rectangular groove. A concave opening is formed on the main bracket pipe, and the main pipe extension groove is aligned with the opening and fixed on both sides of the main bracket pipe. The opening of the main pipe extension groove is flush with the pipe wall of the main bracket pipe where the opening is formed. This invention designs the photovoltaic panel heat dissipation bracket to utilize the "chimney effect," where the photovoltaic panel itself heats the air inside the bracket, accelerating airflow. The photovoltaic panel heat dissipation bracket of this invention has a simple structure, low cost, and requires no maintenance due to the use of natural laws. This technical solution dissipates heat from the bracket through the "chimney effect," but the contact area between the bracket and the photovoltaic panel is small, resulting in limited heat dissipation capacity. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a frame structure that utilizes a photovoltaic panel frame for forced convection heat dissipation, thus solving the problem of poor heat dissipation performance of photovoltaic panels mentioned in the background art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a frame structure for forced convection heat dissipation using a photovoltaic panel frame, comprising a metal fixing frame and a photovoltaic panel disposed above the metal fixing frame. The back of the photovoltaic panel is attached with heat dissipation fins, which extend outward to form an extension arm. A heat-conducting plate is fixedly installed at the end of the extension arm away from the heat dissipation fins. The heat-conducting plate is fixedly connected to the metal fixing frame by bolts, and a heat-conducting pad is disposed between the heat-conducting plate and the metal fixing frame.

[0007] Furthermore, a flow guide plate is fixedly installed on the surface of the metal bracket, the flow guide plate forming a flow channel with openings at both ends larger than the middle, and heat dissipation fins are arranged in the middle of the flow channel.

[0008] Furthermore, the heat dissipation fins are hollow in shape, with openings at both ends, and cross-distributed heat dissipation plates are arranged inside the heat dissipation fins, forming an airflow channel together with the heat dissipation plates.

[0009] Furthermore, a blower fan is connected to and runs through one end of the air duct of the heat dissipation fins, and protective nets are provided at both ends of the air duct of the heat dissipation fins.

[0010] Furthermore, the axis formed by the air duct inlet and outlet of the heat dissipation fins is parallel to the axis of the guide plate flow channel vertically and is set in the east-west direction.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This frame structure utilizes forced convection heat dissipation from photovoltaic panels. By setting heat dissipation fins, the photovoltaic panels can be cooled. The heat dissipation fins are connected to a metal fixing frame, and a thermal pad is set at the connection point. This allows the metal fixing frame, which plays a supporting role, to be connected to the heat exchange part, thereby improving the heat dissipation efficiency.

[0013] 2. This frame structure, which utilizes photovoltaic panels for forced convection cooling, forms a long air duct by setting the heat dissipation fins as hollow cavities and setting continuously spaced heat dissipation plates inside. A blower fan is installed at the air inlet on one side to increase the airflow speed, thereby achieving a better heat dissipation effect. Attached Figure Description

[0019] 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.

[0020] See Figure 1-4 A frame structure for forced convection heat dissipation using a photovoltaic panel frame includes a metal mounting frame 1 and a photovoltaic panel 2 mounted on top of the metal mounting frame 1. Heat dissipation fins 3 are attached to the back of the photovoltaic panel 2, and the heat dissipation fins 3 extend outward to form an extension arm 4. A heat-conducting plate 5 is fixedly installed at the end of the extension arm 4 away from the heat dissipation fins 3. The heat-conducting plate 5 is fixedly connected to the metal mounting frame 1 by bolts 6. A heat-conducting pad 7 is provided between the heat-conducting plate 5 and the metal mounting frame 1. By adding heat dissipation fins 3 to the back of the photovoltaic panel 2, heat dissipation can be achieved. Simultaneously, by increasing the connection between the heat dissipation fins 3 and the metal mounting frame 1 and providing a heat-conducting pad 7 at the connection point, the metal mounting frame 1, which supports the device, can also contribute to heat dissipation.

[0021] A flow guide plate 8 is fixedly installed on the surface of the metal bracket 1. The flow guide plate 8 forms a flow channel with openings at both ends larger than the middle. The heat dissipation fins 3 are set in the middle of the flow channel. By setting the flow guide plate 8, it can have the function of heat dissipation. At the same time, it can form a venturi tube with the heat dissipation fins 3 to increase the flow rate of gas when passing through the heat dissipation fins 3, thereby improving the heat dissipation effect.

[0022] The heat dissipation fin 3 is hollow, with openings at both ends. Inside the heat dissipation fin 3, there are cross-distributed heat dissipation plates 9. The heat dissipation plates 9 and the heat dissipation fin 3 together form an airflow channel. This arrangement increases the contact area between the air and the heat dissipation fin 3, thereby improving the heat dissipation efficiency.

[0023] One end of the air duct of the heat dissipation fin 3 is connected to and passes through a blower fan 10. Both ends of the air duct of the heat dissipation fin 3 are equipped with protective nets 11. With this setting, the temperature of the photovoltaic panel 2 can be collected by the temperature acquisition unit, and the blower fan 10 can be started as needed, thereby forcing airflow and improving heat dissipation efficiency.

[0024] The axis formed by the air inlet and outlet of the heat dissipation fin 3 is parallel to the axis of the flow channel of the guide plate 8 and is set in the east-west direction. Since the photovoltaic panel 2 is generally set in the north-south direction to increase the light-receiving time, by restricting the air duct of the heat dissipation fin 3 and the flow channel of the guide plate 8 to be set in the east-west direction, the photovoltaic panel 2 can avoid blocking the air flow.

[0025] In use, the photovoltaic panel 2 can be cooled by setting heat dissipation fins 3, and the heat dissipation fins 3 are connected to the metal bracket 1. A heat-conducting pad 7 is set at the connection point, so that the metal bracket 1, which plays a supporting role, can be connected to the heat exchange part, thereby improving the heat dissipation efficiency.

[0026] Furthermore, a guide plate 8 that wraps around the heat dissipation fins 3 is connected to the metal mounting bracket 1, and the guide plate 8 and the heat dissipation fins 3 are arranged to form a venturi tube together, thereby accelerating the airflow through the heat dissipation fins 3 and thus increasing the heat dissipation efficiency.

[0027] Furthermore, by setting the heat dissipation fins 3 as a hollow cavity and setting the heat dissipation plates 9 continuously spaced inside to form a longer air duct, and setting a blower fan 10 at one side air inlet to increase the air flow rate, a better heat dissipation effect is achieved.

[0028] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
