[0060] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0061] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0063] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0064] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0065] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0066] like Figures 1 to 4As shown, an embodiment of the present application provides a junction cabinet, which includes a cabinet body 1, and the cabinet body 1 includes a first cavity 11 and a second cavity 12. The first cavity 11 is used to place a first heating element 13, and the second cavity 12 is used to place a second heating element 14. The cabinet body 1 also includes a back plate 18 and a cabinet door 15. On two opposite sides of the first cavity 11, one side is provided with a back plate 18, and the other side is provided with a cabinet door 15. The cabinet door 15 is used to open or close the first cavity 11 and the second cavity 12. The junction cabinet also includes a first heat dissipation component 2 and a second heat dissipation component 3. The first heat dissipation component 2 is installed in the first cavity 11 and is located on a side of the first heating element 13 away from the cabinet door 15. The second heat dissipation component 3 is installed in the second cavity 12 and is located on a side of the second heating element 14 away from the cabinet door 15.

[0067] During the operation of the combiner cabinet, the first heating element 13 and the second heating element 14 will emit heat, causing the temperature in the first cavity 11 and / or the second cavity 12 to be too high, resulting in malfunction of the electronic devices in the combiner cabinet. The first heat dissipation component 2 is arranged in the first cavity 11, which can increase the air flow rate in the first cavity 11, thereby reducing the temperature in the first cavity 11. The second heat dissipation component 3 is arranged in the second cavity 12, which can increase the air flow rate in the second cavity 12, thereby reducing the temperature in the second cavity 12. The cabinet door 15 is used to open or close the first cavity 11 and the second cavity 12. The first heating element 13 and the second heating element 14 are installed in the first cavity 11 and the second cavity 12 through the cabinet door 15. The first heat dissipation component 22 is installed on the side of the first heating element 13 away from the cabinet door 15, and the second heat dissipation component 33 is installed on the side of the second heating element 14 away from the cabinet door 15. The first heat dissipation component 2 and the second heat dissipation component 3 hinder the possibility of installing the first heating element 13 and the second heating element 14. A shutter structure is provided at positions of the cabinet door 15 corresponding to the first cavity 11 and the second cavity 12. When the cabinet door 15 is closed, the first cavity 11 and the second cavity 12 can be connected to the outside, which is beneficial to improving the heat dissipation effect of the first cavity 11 and the second cavity 12.

[0068] like Figure 3 , Figure 4 and Figure 5 As shown, the second heat dissipation assembly 3 includes a second mounting plate 31, a third mounting plate 32 and a plurality of second heat dissipation elements 33, the second mounting plate 31 is connected to the inner wall of the second cavity 12, and the second mounting plate 31 is provided with a window 311, the window 311 is aligned with the second heat generating element 14, and the third mounting plate 32 is detachably mounted on the second mounting plate 31 and can block the window 311. The third mounting plate 32 is used to mount the second heat dissipation element 33.

[0069] Some components in the second heating element 14 will generate a relatively high voltage during operation. In order to reduce safety issues caused by accidental touches, a protective net 4 is provided in the second cavity 12, and the second cavity 12 is divided into a front compartment and a rear compartment. The front compartment is located on the side close to the cabinet door 15, and the rear compartment is located on the side close to the back panel 18. The components that generate high voltage current in the second heating element 14 are installed in the rear compartment. When a component that can generate high voltage in the second heating element 14 fails, it is inconvenient for the staff to repair it from the side of the cabinet door 15 due to the obstruction of the protective net 4. The window 311 on the second mounting plate 31 is provided corresponding to the second heating element 14, and the third mounting plate 32 is detachably mounted on the second mounting plate 31. When the back panel 18 and the third mounting plate 32 are removed, the second heating element 14 is exposed to the window 311 of the second mounting plate 31, which is convenient for the staff to repair. The second heat sink 33 can be a heat dissipation fan. When the third mounting plate 32 is installed on the second mounting plate 31, the third mounting plate 32 blocks the window 311 of the second mounting plate 31, which can limit the flow direction of air in the second cavity 12, so that the airflow blown out by the second heat sink 33 flows through the second heating element 14 and flows out from the louver structure on the cabinet door 15, which is beneficial to improve the heat dissipation effect of the second heating element 14.

[0070] like Figure 5 As shown, in a possible embodiment, the second mounting plate 31 includes a flange 312. The flange 312 is disposed at the edge of the window 311, one end of which is connected to the side wall of the edge of the window 311, and the other end is bent to a side away from the third mounting plate 32.

[0071] The second mounting plate 31 is provided with a window 311, so that there is a hollow part on the second mounting plate 31, which reduces the strength of the second mounting plate 31 and causes deformation near the window 311. The flange 312 is provided at the edge of the window 311 to improve the strength of the second mounting plate 31 and reduce the possibility of deformation of the second mounting plate 31. The flange 312 is bent toward the side away from the third mounting plate 32, which can reduce the possibility of interference between the flange 312 and the third mounting plate 32.

[0072] like Figure 5 and Figure 8 As shown, in a possible embodiment, the second mounting plate 31 includes a second connecting portion 341313, which extends away from the third mounting plate 32 and is used to connect to the inner wall of the second cavity 12. The second connecting portion 341313 and the second mounting plate 31 can be an integrally formed structure.

[0073] The second mounting plate 31 and the inner wall of the second cavity 12 can be connected by welding, bonding, etc., and the second connecting portion 341313 extends in a direction away from the third mounting plate 32, thereby increasing the contact area between the second mounting plate 31 and the inner wall of the second cavity 12, which is beneficial to improving the reliability of the second mounting plate 31 after being installed in the second cavity 12.

[0074] like Figure 2 and Figure 5 As shown, in a possible embodiment, the cabinet 1 includes a plurality of cross beams 16 and a plurality of longitudinal beams 17, and the back plate 18 and the side plate 19 for enclosing the first cavity 11 and the second cavity 12 are both installed on the cross beams 16 and the longitudinal beams 17. The back plate 18 and the side plate 19 are located on the side of the cross beams 16 and the longitudinal beams 17 away from the second cavity 12 and / or the second cavity 12, so the cross beams 16 and the longitudinal beams 17 will protrude from the side wall of the second cavity 12. The second mounting plate 31 includes a positioning groove 211, and after the second mounting plate 31 is installed in the second cavity 12, the cross beam 16 is located in the positioning groove 211.

[0075] The second mounting plate 31 is provided with a positioning groove 211, so that the second mounting plate 31 can avoid the cross beam 16, reducing the possibility of interference between the second mounting plate 31 and the cross beam 16. When installing the second mounting plate 31, it is necessary to align the positioning groove 211 with the cross beam 16, so as to achieve the positioning of the second mounting plate 31, which is conducive to reducing the possibility of the second mounting plate 31 being installed upside down or incorrectly. After the second mounting plate 31 is installed, the cross beam 16 contacts the side wall of the positioning groove 211, and the position of the second mounting plate 31 in the second cavity 12 can be limited by the cross beam 16, which is conducive to improving the stability of the second mounting plate 31 after being installed in the second cavity 12.

[0076] In a possible embodiment, the material of the second mounting plate 31 may be carbon structural steel, and the specific steel grade may be Q235B. This steel has a certain elongation and strength, and has good toughness and castability, which facilitates the processing of the second mounting plate 31. At the same time, this steel has a low price, which can reduce the production cost of the junction cabinet.

[0077] The thickness of the second mounting plate 31 can be 1.8 mm to 2.2 mm, specifically 1.8 mm, 2.0 mm, 2.2 mm, etc., preferably 2.0 mm. If the thickness of the second mounting plate 31 is less than 1.8 mm, its strength is relatively low, causing the second mounting plate 31 to be easily deformed and unable to carry the third mounting plate 32 and the second heat sink 33. If the thickness of the second mounting plate 31 is greater than 2.2 mm, the space occupied by the second mounting plate 31 in the second cavity 12 will be increased, and the production cost of the second mounting plate 31 will also be increased.

[0078] like Figure 6 and Figure 7As shown, in a possible embodiment, the third mounting plate 32 includes a plurality of mounting holes 321, and the plurality of second heat sinks 33 are mounted on the third mounting plate 32 through the mounting holes 321. A reinforcing rib 34 is also provided on the third mounting plate 32, and the reinforcing rib 34 protrudes from the surface of the third mounting plate 32. The plurality of mounting holes 321 are symmetrically arranged about the reinforcing rib 34.

[0079] The third mounting plate 32 is provided with mounting holes 321, so that the second heat sink 33 can be mounted on the second mounting plate 31 through the third mounting plate 32. After the third mounting plate 32 is provided with mounting holes 321, the strength of the third mounting plate 32 is reduced, and the position of the third mounting plate 32 near the mounting holes 321 is prone to deformation. The third mounting plate 32 is provided with reinforcing ribs 34, and the plurality of mounting holes 321 are symmetrically arranged relative to the reinforcing ribs 34, so that the possibility of deformation of the third mounting plate 32 can be reduced.

[0080] In a possible embodiment, the reinforcing rib 34 protrudes from the third mounting plate 32 and is located on a side of the third mounting plate 32 close to or away from the second heating element 14 .

[0081] The reinforcing rib 34 is located on the side of the third mounting plate 32 close to or away from the second heating element 14, which can improve the strength of the third mounting plate 32 and reduce the possibility of deformation of the third mounting plate 32. The reinforcing rib 34 is arranged on the side of the third mounting plate 32 away from the second heating element 14, and when the distance between the third mounting plate 32 and the second heating element 14 is small, the possibility of interference between the reinforcing rib 34 and the second heating element 14 can be reduced. The reinforcing rib 34 is arranged on the side of the third mounting plate 32 close to the second heating element 14, and when the distance between the third mounting plate 32 and the back plate 18 is small, the possibility of interference between the reinforcing rib 34 and the back plate 18 can be reduced.

[0082] like Figure 6 As shown, in a possible embodiment, the reinforcing rib 34 includes a connecting portion 341 and a protruding portion 342, and there is an angle between the protruding portion 342 and the connecting portion 341, so that the reinforcing rib 34 is an L-shaped structure. The connecting portion 341 is connected to the third mounting plate 32, and the protruding portion 342 protrudes from the third mounting plate 32 along the thickness direction of the third mounting plate 32.

[0083] There is an angle between the protrusion 342 and the connection portion 341, so that the protrusion 342 can protrude from the third mounting plate 32, thereby improving the strength of the third mounting plate 32 and reducing the possibility of deformation of the third mounting plate 32. The connection portion 341 and the third mounting plate 32 can be connected by bonding or welding. The reinforcing rib 34 can also be an integrally formed structure with the third mounting plate 32, thereby reducing the possibility of the reinforcing rib 34 falling off, which is conducive to improving the reliability of the third mounting plate 32.

[0084] like Figure 6 and Figure 8 As shown, in a possible embodiment, along the height direction of the combiner cabinet, one end of the third mounting plate 32 is provided with a first bending portion 322, and the other end is provided with a second bending portion 323. The first bending portion 322 and the second bending portion 323 are both integrally formed with the third mounting plate 32 to reduce the possibility of the first bending portion 322 and the second bending portion 323 falling off.

[0085] A first bending portion 322 and a second bending portion 323 are respectively provided at both ends of the third mounting plate 32, which can improve the strength of the third mounting plate 32 and reduce the possibility of deformation of the third mounting plate 32. In a possible embodiment, the reinforcing rib 34 extends along the length direction of the third mounting plate 32, and the first bending portion 322, the second bending portion 323 and the reinforcing rib 34 form an I-shaped structure, which can reduce the possibility of deformation of the third mounting plate 32 along the length direction and the width direction of the third mounting plate 32 and improve the strength of the third mounting plate 32.

[0086] like Figure 6 , Figure 7 and Figure 8 As shown, in a possible embodiment, the first bending portion 322 and the second bending portion 323 are both bent in a direction away from the second mounting plate 31 .

[0087] The third mounting plate 32 and the second mounting plate 31 can be connected by screws, so the surface of the third mounting plate 32 needs to be in contact with the surface of the second mounting plate 31, and the first bending portion 322 and the second bending portion 323 are bent in a direction away from the second mounting plate 31, which can reduce the possibility of interference between the first bending portion 322 and the second bending portion 323 and the second mounting plate 31, which is conducive to improving the reliability of the connection between the third mounting plate 32 and the second mounting plate 31. The first bending portion 322 and the second bending portion 323 are bent in a direction away from the second mounting plate 31, and when the third mounting plate 32 is installed on the second mounting plate 31, it is convenient for the staff to take the third mounting plate 32 through the second bending portion 323 and the second bending portion 323.

[0088] In a possible embodiment, the thickness of the third mounting plate 32 is 1.8 mm to 2.2 mm, specifically 1.8 mm, 2.0 mm, 2.2 mm, preferably 2.0 mm.

[0089] The third mounting plate 32 is provided with mounting holes 321 for mounting the second heat sink 33. If the thickness of the third mounting plate 32 is less than 1.8 mm, the strength of the third mounting plate 32 is relatively low, and it is easy to deform, and cannot bear multiple second heat sinks 33. If the thickness of the third mounting plate 32 is greater than 2.2 mm, the weight of the third mounting plate 32 is relatively large, which in turn increases the bearing weight required by the second mounting plate 31, increases the possibility of deformation of the second mounting plate 31, and also increases the production cost of the third mounting plate 32.

[0090] In a possible embodiment, the third mounting plate 32 is a rectangular structure with a length of 970 mm to 980 mm and a width of 625 mm to 635 mm.

[0091] The length of the third mounting plate 32 can be 970 mm, 975 mm, 980 mm, etc., preferably 975 mm. The width of the third mounting plate 32 can be 625 mm, 630 mm, 635 mm, etc., preferably 630 mm. The third mounting plate 32 of the above size is larger than the size of the window 311, so that the third mounting plate 32 can block the window 311 in the second mounting plate 31. The third mounting plate 32 is detachably mounted on the second mounting plate 31 by screws, and the edge of the third mounting plate 32 of the above size will overlap with the second mounting plate 31, which is convenient for setting screws. If the size of the third mounting plate 32 is too small, the third mounting plate 32 will not be able to block the window 311 or be installed on the second mounting plate 31. If the size of the third mounting plate 32 is too large, the third mounting plate 32 may interfere with the inner wall of the second cavity 12 or the beam 16 protruding from the inner wall of the second cavity 12, which will also lead to waste of steel and increase the production cost of the third mounting plate 32.

[0092] like Figure 2 , Figure 8 , Fig. 9 and Fig.10 As shown, in a possible embodiment, the first heat dissipation assembly 2 includes a first mounting plate 21 and a first heat dissipation member 22, the first mounting plate 21 is connected to the inner wall of the first cavity 11, and the first heat dissipation member 22 is mounted on the first mounting plate 21. The first mounting plate 21 includes a first connecting portion 341212, the first connecting portion 341212 is located at the edge of the first mounting plate 21, extends in a direction close to or away from the first heat dissipation member 13, and is used to connect to the inner wall of the first cavity 11.

[0093] The first mounting plate 21 and the inner wall of the first cavity 11 can be connected by welding or bonding, and the first connecting portion 341212 can increase the contact area between the first mounting plate 21 and the inner wall of the first cavity 11, and can increase the reliability of the first mounting plate 21 after being connected to the inner wall of the first cavity 11. The first connecting portion 341212 is located at the edge of the first mounting plate 21, extending in a direction close to or away from the first heating element 13, and can increase the strength of the edge of the first mounting plate 21 and reduce the possibility of deformation of the first mounting plate 21. The first connecting portion 341212 can be an integrally formed structure with the first mounting plate 21, which can reduce the possibility of the first connecting portion 341212 falling off, and is conducive to improving the reliability of the first mounting plate 21.

[0094] like Figure 2 , Fig. 9 and Fig.10 As shown, in a possible embodiment, a plurality of beams 16 are provided in the first cavity 11 and protrude from the inner wall of the first cavity 11. The first mounting plate 21 includes a positioning groove 211. After the first mounting plate 21 is mounted on the first cavity 11, the beams 16 protruding from the inner wall of the first cavity 11 are located in the positioning groove 211.

[0095] A positioning groove 211 is provided on the first mounting plate 21, so that the first mounting plate 21 can avoid the cross beam 16, reducing the possibility of interference between the first mounting plate 21 and the cross beam 16. When installing the first mounting plate, the positioning groove 211 needs to be aligned with the cross beam 16, so that the first mounting plate 21 can be positioned, which is conducive to reducing the possibility of the first mounting plate 21 being installed upside down or incorrectly. After the first mounting plate 21 is installed, the cross beam 16 contacts the side wall of the positioning groove 211, and the position of the first mounting plate 21 in the first cavity 11 can be limited by the cross beam 16, which is conducive to improving the stability of the first mounting plate 21 after being installed in the first cavity 11.

[0096] In a possible embodiment, the material of the first mounting plate 21 may be carbon structural steel, and the specific steel grade may be Q235B. This steel has a certain elongation and strength, good toughness and castability, and is convenient for processing the first mounting plate 21. At the same time, this steel has a low price, which can reduce the production cost of the junction cabinet.

[0097] The thickness of the first mounting plate 21 can be 1.8 mm to 2.2 mm, specifically 1.8 mm, 2.0 mm, 2.2 mm, etc., preferably 2.0 mm. If the thickness of the first mounting plate 21 is less than 1.8 mm, its strength is relatively low, and the first mounting plate 21 is easily deformed. If the thickness of the first mounting plate 21 is greater than 2.2 mm, the space occupied by the first mounting plate 21 in the first cavity 11 will be increased, and the production cost of the first mounting plate 21 will also be increased.

[0098] The present application relates to a junction cabinet, wherein the cabinet body 1 of the junction cabinet comprises a first cavity 11 and a second cavity 12, wherein a first heating element 13 and a first heat sink 22 are arranged in the first cavity 11, and a second heating element 14 and a second heat sink 33 are arranged in the second cavity 12. The first mounting plate 21 in the first heat sink 22 is connected to the inner wall of the first cavity 11, and the first heat sink 22 is mounted on the first mounting plate 21. The second mounting plate 31 in the second heat sink assembly 3 is connected to the inner wall of the second cavity 12, the third mounting plate 32 is detachably mounted on the second mounting plate 31, and the second heat sink 33 is mounted on the third mounting plate 32. The second mounting plate 31 is provided with a window 311, and the third mounting plate 32 can block the window 311, and the second heating element 14 is aligned with the window 311. After the third mounting plate 32 is detached from the second mounting plate 31, the second heating element 14 can be repaired through the window 311. The third mounting plate 32 is provided with reinforcing ribs 34 , and a plurality of mounting holes 321 for mounting the second heat sink 33 are symmetrically arranged about the reinforcing ribs 34 , which can improve the strength of the third mounting plate 32 and reduce the possibility of deformation of the third mounting plate 32 .
