Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell technology, and more specifically to a photovoltaic cell heat dissipation structure that utilizes thermal gel. Background Technology

[0002] As is widely known, photovoltaic cells, also known as solar cells, are semiconductor devices that can directly convert solar energy into electrical energy. A solar panel, which is composed of multiple solar cells, consists of a front glass, electrodes and wires, a back sheet, and a frame. Through the cooperation of these components, the solar panel converts solar energy into electrical energy to meet power supply needs in daily life.

[0003] The specific steps for installing a solar panel composed of solar cells include fixing the bracket, placing the solar panel on the bracket, fixing the solar panel with threaded fasteners, electrical inspection after installation, and visual inspection. When sunlight shines on the solar panel, based on the photovoltaic effect, the semiconductors in the cell absorb light energy, causing electrons to move and form an electric current, thus realizing the conversion of light energy into electrical energy.

[0004] After the solar panels are installed, during long-term daily use, the back of the solar panels usually does not have a heat dissipation structure. Heat is dissipated only by the flow of natural wind. However, the heat dissipation capacity of natural wind is limited, and the overall heat dissipation effect is poor. There is a situation where the solar panels are overheated, which affects the power generation efficiency. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, one objective of this utility model is to provide a photovoltaic cell heat dissipation structure using heat dissipation gel to solve the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides a photovoltaic cell heat dissipation structure using heat dissipation gel, including a support body with a placement portion, and further including: a solar panel disposed on the placement portion; guide portions opposite to each other on the placement portion, and a heat dissipation back plate slidably disposed on each guide portion in contact with the solar panel; and a limiting rod disposed on the frame edge of the support body; when the heat dissipation back plate and the solar panel come into contact, the limiting rod limits the frame edge of the heat dissipation back plate.

[0007] Preferably, the solar panel consists of a photovoltaic cell array and an outer frame connected to the photovoltaic cell array.

[0008] Preferably, the placement part is a rectangular structure that fits the outer frame.

[0009] Preferably, a guide groove is provided on the frame edge of the bracket body, and the guide groove slides in conjunction with the limiting rod.

[0010] Preferably, the heat dissipation backplate consists of a copper plate and a frame connected to the copper plate, with sliders disposed opposite to each other on the frame.

[0011] Preferably, each of the sliders is a rectangular structure that slides in conjunction with each of the guide portions.

[0012] Preferably, each of the guide portions is provided with a positioning hole, and each of the sliders is provided with a protrusion that engages with the positioning hole.

[0013] Preferably, the copper plate has a dorsal fin portion in the width direction, and the dorsal fin portion is composed of multiple rectangular fins.

[0014] Preferably, the limiting rod is provided with a protrusion, which is specifically a rectangular structure.

[0015] Preferably, the bracket body has a locking part that engages with the protrusion.

[0016] In the above technical solution, the photovoltaic cell heat dissipation structure using heat dissipation gel provided by this utility model has the following beneficial effects: Before the solar panel is installed, the heat dissipation back plate is slidably installed on the guide part on the bracket body, and then the solar panel is placed on the placement part. At this time, the back plate of the solar panel is in contact with the heat dissipation back plate. Finally, the heat dissipation back plate is limited by the limit rod installed on the frame edge of the bracket body, which improves the stability of the heat dissipation back plate after installation. This device improves the heat dissipation effect of the solar panel by installing the heat dissipation back plate on the bracket body and contacting the solar panel, and transferring the heat dissipated from the back of the solar panel to the heat dissipation back plate for heat dissipation through the physical structure. This reduces or even avoids the situation where the back of the solar panel is not provided with a heat dissipation structure and only relies on the flow of natural wind to dissipate heat. However, the heat dissipation capacity of natural wind is limited, the overall heat dissipation effect is poor, and the solar panel may affect the power generation efficiency due to overheating.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-9 This utility model provides a technical solution, including the following embodiments:

[0031] Example 1

[0032] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, the bracket body 1 has a placement part 1.1 and also includes: a solar panel 2, which is disposed on the placement part 1.1; a guide part 1.2 is provided on the placement part 1.1, and a heat dissipation back plate 3 that is in contact with the solar panel 2 is slidably disposed on each guide part 1.2; and a limiting rod 4, which is disposed on the frame edge of the bracket body 1; when the heat dissipation back plate 3 and the solar panel 2 come into contact, the limiting rod 4 limits the frame edge of the heat dissipation back plate 3.

[0033] Before installing the solar panel 2, the heat dissipation backplate 3 is slidably installed onto the guide part 1.2 on the bracket body 1. Then, the solar panel 2 is placed on the placement part 1.1. At this time, the backplate of the solar panel 2 is in contact with the heat dissipation backplate 3. Finally, the limiting rod 4 is installed on the frame edge of the bracket body 1 to limit the heat dissipation backplate 3, thereby improving the stability of the heat dissipation backplate 3 after installation. This device, by installing the heat dissipation backplate 3 on the bracket body 1 and contacting the solar panel 2, transfers the heat dissipated from the back of the solar panel 2 to the heat dissipation backplate 3 through a physical structure, thereby improving the heat dissipation effect of the solar panel 2. This reduces or even avoids the situation where the back of the solar panel is not equipped with a heat dissipation structure and only relies on the flow of natural wind to dissipate heat. However, the heat dissipation capacity of natural wind is limited, the overall heat dissipation effect is poor, and there is a situation where the solar panel is overheated and the power generation efficiency is affected.

[0034] In this embodiment, the limiting rod 4 restricts the displacement of the heat dissipation backplate 3 after installation, ensuring close contact between the heat dissipation backplate 3 and the solar panel 2 backplate. This prevents separation due to vibration, wind pressure, or other factors, thus ensuring the continuity and stability of heat conduction. The area where the heat dissipation backplate 3 contacts the solar panel 2 is made of copper, which has excellent thermal conductivity. Furthermore, the heat dissipation backplate 3 is coated with a thermally conductive coating, such as... Figure 3 As shown in the diagram, the thermally conductive coating is specifically a heat dissipation gel (thermal conductive gel). By filling the gap between the solar panel 2 and the heat dissipation backplate 2 when they come into contact (and by using its own viscoelasticity, the two can maintain a flexible but tight contact under vibration and wind pressure, eliminating contact thermal resistance), heat can be quickly conducted to the heat dissipation backplate, thus improving the heat dissipation effect.

[0035] Example 2

[0036] Combination Figure 3 and Figure 4 As shown, this embodiment further describes the solar panel 2 provided in Embodiment 1. The solar panel 2 consists of a photovoltaic cell array and an outer frame connected to the photovoltaic cell array. The placement part 1.1 is specifically a rectangular structure, adapted to the outer frame. Furthermore, the placement part 1.1 has at least four threaded portions 1.6, such as... Figure 9 As shown in the figure, the specific number of the threaded parts 1.6 is set according to the needs of those skilled in the art. Multiple threaded parts 1.6 are used to correspond to the threaded holes on the outer frame of the solar panel 2 and to be threadedly connected by threaded fasteners, thereby completing the installation of the solar panel 2 and the bracket body 1.

[0037] Example 3

[0038] Combination Figure 4 , Figure 6As shown in Figure 9, this embodiment is an optimization based on the bracket body 1 provided in Embodiment 1. A guide groove 1.4 is provided on the frame edge of the bracket body 1, and the guide groove 1.4 slides in cooperation with the limiting rod 4.

[0039] During operation, the heat sink backplate 3 is installed by sliding the limiting rod 4 with the guide groove 1.4. When the sliding stroke of the limiting rod 4 ends, the limiting rod 4 limits the heat sink backplate 3. The limiting of the limiting rod 4 improves the stability of the heat sink backplate 3 after installation.

[0040] In this embodiment, the end of the limiting rod 4 is provided with a toggle part 4.2. The toggle part 4.2 facilitates the operator to slide the limiting rod 4 in the guide groove 1.4 for installation and removal. The toggle part 4.2 is rectangular in shape, and its end extends to the outside of the frame edge of the bracket body 1, which is convenient for the operator to toggle by hand.

[0041] Example 4

[0042] Combination Figure 5 and Figure 8 As shown, this embodiment further describes the structure and installation of the heat dissipation backplate 3 provided in Embodiment 1. The heat dissipation backplate 3 consists of a copper plate and a frame connected to the copper plate. Slider 3.1 are arranged opposite to each other on the frame. Each slider 3.1 is specifically a rectangular structure, which slides in cooperation with each guide part 1.2. Each guide part 1.2 has a positioning hole 1.3. Each slider 3.1 has a protrusion 3.2 that engages with each positioning hole 1.3. A dorsal fin part 3.3 is provided in the width direction of the copper plate. The dorsal fin part 3.3 is composed of multiple rectangular fins. Furthermore, the engagement of each protrusion 3.2 with the positioning hole 1.3 improves the stability of the heat dissipation backplate 3 after installation. The dorsal fin part 3.3 on the copper plate allows heat to be transferred from the copper plate to the rectangular fins of the dorsal fin part 3.3, which then have a larger surface area to contact the air, accelerating heat dissipation and improving the heat dissipation effect of the heat dissipation backplate 3.

[0043] Example 5

[0044] Combination Figure 7 As shown, preferably, the limiting rod 4 is provided with a protrusion 4.1, which is specifically a rectangular structure. The bracket body 1 is provided with a locking part 1.5 that engages with the protrusion 4.1. Furthermore, the engagement of the limiting rod 4 with the locking part 1.5 at the end of its sliding stroke improves the stability of the limiting rod 4 after installation. Secondly, the engagement of the two parts facilitates the disassembly of the limiting rod 4 and makes it convenient to replace the heat dissipation backplate 3.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
