Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel structure technology, and in particular to a photovoltaic panel junction box. Background Technology

[0002] Junction boxes can centrally output the current generated by photovoltaic cells, while providing safe and reliable connection points for easy connection to external circuits and preventing current from flowing back into the solar panel. In existing junction boxes, the internal space is small, and diodes are mounted directly inside the box, generating significant heat during operation. This can easily damage the diodes' structure and cause the junction box to reach high temperatures, ultimately affecting the quality of the photovoltaic panel. Utility Model Content

[0003] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a photovoltaic panel junction box, which facilitates heat dissipation of the diodes inside the junction box, reduces the temperature of the diodes during operation, and protects the structure of the diodes.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A photovoltaic panel junction box includes a box body, a support structure disposed within the box body, and a diode assembly connected to the support structure. The support structure includes a support member with a cross-shaped channel inside. The diode assembly includes a diode and copper plates disposed on both sides of the diode. The copper plates are C-shaped and supported on both sides of the support member. The diode assembly is disposed at the upper end of the support member, leaving the channel unattended.

[0006] Preferably, the support structure also includes a surrounding panel, which encloses a cavity within the box, and the support member is disposed within the cavity.

[0007] Preferably, the support structure also includes a partition, one end of which is connected to the box body and the other end of which is connected to the surrounding plate. The surrounding plate and the partition form a cavity inside the box body.

[0008] Preferably, a rivet is provided inside the cavity, and a through hole is provided on the copper plate, into which the rivet is inserted.

[0009] Preferably, the support includes a support block and a connecting block, the support block and the connecting block are connected, and the through groove is disposed inside the support block and the connecting block.

[0010] Preferably, the support block is provided with protrusions, and the copper plate is supported on the protrusions.

[0011] This utility model has the following advantages and beneficial effects:

[0012] In this invention, the copper plate has a bent design on both sides to support the diode, which facilitates the diode's heat dissipation. Air can enter in the direction of channel I to lower the internal temperature of the housing. At the same time, the heat of the diode can be dissipated along the direction of channel II to the surrounding plate. The heat on the surrounding plate is then dissipated through the cavity, so that the diode can dissipate heat fully during operation and protect the quality of the diode to the greatest extent.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a photovoltaic panel junction box includes a box body 1, a support structure disposed inside the box body 1, and a diode assembly connected to the support structure. The box body 1 has a circular design and a top cover 11 is detachably fitted to the box body 1. A locking block 111 is provided on the top cover 11, and a locking groove 101 is provided on the box body 1 to cooperate with the locking block 111. When the box body 1 and the top cover 11 are connected, the locking block 111 is connected inside the locking groove 101 to prevent the top cover 11 from rotating during the operation of the junction box, and at the same time facilitates positioning during installation and disassembly, and is used to close the box body 1. The supporting structure includes a support member, a surrounding plate 2, and a partition plate 3. The surrounding plate 2 encloses a cavity 21 inside the box body 1. The support member is placed inside the cavity 21, which faces the wiring port A of the box body 1. One end of the partition plate 3 is connected to the box body 1, and the other end is connected to the surrounding plate 2. The surrounding plate 2 and the partition plate 3 enclose a cavity 31 inside the box body 1. Compared with traditional junction boxes, the surrounding plate 2 and the partition plate 3 separate multiple spaces, increasing the heat dissipation space inside the junction box and facilitating heat dissipation inside the junction box. At the same time, the partition plate 3 holds the surrounding plate 2 in place to prevent deformation, which greatly increases the stability of the overall structure.

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the support component has a cross-shaped channel inside. The support component includes a support block 4 and a connecting block 5, which are connected. The connecting block 5 is located in the middle of the cavity 21, and a support block 4 is closely attached to each side of the connecting block 5. The channel is located inside the support block 4 and the connecting block 5, and includes channel I 41 and channel II 51. Channel I 41 and channel II 51 are arranged perpendicular to each other. Channel I 41 passes through the support block 4 and the connecting block 5 and is oriented towards the junction box's connection port A. Channel II 51 passes through the connecting block 5 and is oriented towards the surrounding plate 2. The connecting block 5 has a U-shaped structure with channel II 51. The two ends of the connecting block 5 are supported by the support blocks 4 on both sides, and there is a gap between the support block 4 and the box 1 to facilitate heat dissipation of the support block 4. The diode assembly includes a diode 7 and copper plates 71 disposed on both sides of the diode 7. A rivet 6 is disposed in the cavity 21. A through hole 711 is disposed on the copper plate 71. The rivet 6 is inserted into the through hole 711. The rivet 6 can provide a positioning function for the installation of the diode assembly. The copper plate 71 is C-shaped and is supported on both sides of the support member. The diode assembly is disposed on the upper end of the support member and the slot is left open. A protrusion 42 is disposed on the support block 4. The copper plate 71 is supported on the protrusion 42. The diode 7 is supported on the connecting block 5.

[0024] like Figures 1-5As shown, the copper plate 71 has a bent design on both sides to support the diode 7. The channel is designed at the lower end of the diode 7. Air can enter in the direction of channel I 41 to reduce the internal temperature of the housing 1. At the same time, the heat of the diode 7 can be dissipated along the direction of channel II 51 to the surrounding plate 2. The heat on the surrounding plate 2 is then dissipated through the cavity 31, which allows the diode 7 to dissipate heat fully during operation, greatly protecting the quality of the diode 7 and increasing its service life. The entire structure adds some space inside the housing 1, which greatly avoids the diode 7 from generating high temperatures during operation, thus preventing the quality of the housing 1 from being affected.

[0025] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
