Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Embodiment 1
[0026] As Figures 1-5As shown in the figure, the utility model provides a technical solution: a solar junction box with a heat dissipation structure, including: a heat dissipation mechanism 1, and a closing mechanism 2 is arranged on the inner wall of the heat dissipation mechanism 1. The heat dissipation mechanism 1 includes a box body 11, and a hollow cavity 12 is arranged on the inner wall of the box body 11. The inner wall of the box body 11 is fixedly connected through penetration with the outside of the hollow cavity 12. One end of the hollow cavity 12 is provided with a connecting plate 17, and one end of the hollow cavity 12 is fixedly connected with one end of the connecting plate 17. A knob 18 is arranged inside the connecting plate 17, and one end of the knob 18 penetrates and is movably connected with the inside of the connecting plate 17. One end of the knob 18 is provided with a guide plate 110, and one end of the knob 18 is fixedly connected with one end of the guide plate 110. A limiting rod 19 is arranged on the outer side of one end of the knob 18, and one end of the outer side of the knob 18 is fixedly connected with one end of the limiting rod 19. The other end of the limiting rod 19 is in movable contact with the inner wall of the connecting plate 17. A plug rod 112 is arranged on the inner wall of one end of the knob 18, and one end of the inner wall of the knob 18 is clamped with one end of the plug rod 112. A back plate 111 is arranged on the outer side of the plug rod 112, and the outer side of the plug rod 112 penetrates and is connected with the inside of the back plate 111. One end of the side surface of the back plate 111 is clamped with the inner wall of one side of the connecting plate 17. One end of the hollow cavity 12 is provided with a copper sheet 14, and one end of the hollow cavity 12 is fixedly connected with one end of the copper sheet 14. Heat dissipation fins 16 are arranged on the inner wall of the hollow cavity 12, and the inner wall of the hollow cavity 12 is fixedly connected through penetration with one end of the heat dissipation fins 16. One end of the hollow cavity 12 is provided with a side plate 13, and one end of the hollow cavity 12 is fixedly connected with one end of the side plate 13. Blades 15 are arranged on the inner side of the other end of the side plate 13, and one end of the inner side of the side plate 13 is movably connected with one end of the blades 15.
[0027] In this embodiment, when dissipating heat from the inside of the solar junction box, a hollow cavity 12 is installed inside the box body 11. The design of the hollow cavity 12 can provide more heat dissipation space, making it easier for heat to be dissipated through air convection, conduction, and radiation. Copper sheets 14 and heat dissipation fins 16 are respectively installed on the hollow cavity 12. When the temperature is generated inside the box body 11, the copper sheets 14 and the heat dissipation fins 16 can absorb heat and effectively dissipate it to the external environment, preventing the temperature inside the box body 11 from being too high. In addition, by rotating the knob 18, the angles of the two guide plates 110 are changed to have a certain inclination angle. In this way, the external wind resources can be utilized more effectively, more wind can be introduced into the hollow cavity 12, the heat exchange with the outside is increased, and the air cooling efficiency is improved. This helps to quickly discharge the heat when it accumulates and maintain the stable operation state of the equipment. Furthermore, blades 15 are installed at the end position of the hollow cavity 12. When the blades 15 are affected by the external wind force, the air flow speed can be increased, and the air can flow faster inside the box body 11;
[0028] In addition, by combining the insertion rod 112 with the back plate 111 and then engaging the insertion rod 112 with the inner wall of the knob 18, the deflector 110 will be restricted and kept stationary at the adjusted angle, which can prevent the deflector 110 from accidentally swinging under the action of external wind force and maintain the stability of its set angle.
[0029] Embodiment 2
[0030] As Figures 1-5 shown, the closing mechanism 2 includes a closing plate 21, a sealing strip 22 is arranged on the outer side of the closing plate 21, the outer side of the closing plate 21 is fixedly connected to the inner side of the sealing strip 22, the outer side of the sealing strip 22 is vertically fitted with the inner wall of the hollow cavity 12, and the inner wall of the hollow cavity 12 is vertically penetrated and connected to one end of the closing plate 21.
[0031] In this embodiment, in order to prevent rainwater from entering the box body 11 along the path of the hollow cavity 12, the closing plate 21 can be vertically clamped with the hollow cavity 12 to block the flow path in the hollow cavity 12. A sealing strip 22 is installed on the closing plate 21, and the installation of the sealing strip 22 further enhances the waterproof effect, ensuring that moisture cannot penetrate into the box body 11 through the gap between the closing plate 21 and the hollow cavity 12. Rainwater entering the box body 11 may cause damage to the internal equipment, such as short circuit, corrosion, etc. By preventing rainwater from entering, the closing plate 21 and the sealing strip 22 provide an additional protective layer to ensure that the internal equipment is protected from moisture and its service life is extended.

[0033] As Figures 1-5 shown, a hollow cavity 12 is installed inside the box body 11, and a copper sheet 14 and a heat sink 16 are respectively installed on the hollow cavity 12. When the temperature is generated inside the box body 11, the copper sheet 14 and the heat sink 16 can absorb heat and effectively dissipate it to the external environment. In addition, by rotating the knob 18, the angles of the two deflectors 110 are changed to have a certain inclination angle. In this way, the external wind resources can be utilized more effectively, more wind can be introduced into the hollow cavity 12, the heat exchange with the outside is increased, and the air cooling efficiency is improved. Furthermore, a blade 15 is installed at the end of the hollow cavity 12. When the blade 15 is affected by the external wind force, the air flow speed can be increased, and the air can flow faster inside the box body 11;
[0034] By vertically clamping the closing plate 21 with the hollow cavity 12, the flow path in the hollow cavity 12 is blocked. A sealing strip 22 is installed on the closing plate 21, and the installation of the sealing strip 22 further enhances the waterproof effect, ensuring that moisture cannot penetrate into the interior of the box body 11 through the gap between the closing plate 21 and the hollow cavity 12, and ensuring that the internal equipment is protected from moisture.
