[0047] The present application provides a network device 100, such as Figure 1-4 As shown, including:

[0048] The box body 1 comprises a top plate 10, a side plate 11 and a bottom plate 12. The box body 1 surrounded by the top plate 10, the side plate 11 and the bottom plate 12 may have a first plug interface 13 and a second plug interface 14. The first plug interface 13 is located on one side of the box body 1, and the second plug interface 14 is located on the other side of the box body 1. The first plug interface 13 and the second plug interface 14 are arranged opposite to each other. The first plug interface 13 and the second plug interface 14 may be relative concepts and may be arranged according to actual needs.

[0049] The data module 2 is arranged at the first plug interface 13 of the box body 1. The first plug interface 13 is used for plugging in the data module 2. The data module 2 can be a board for data exchange and processing such as a main control board, a service board and a line card, and the number of the data module 2 is at least one. According to different requirements, when multiple data modules 2 are provided, they can respectively include a main control board, a service board and a line card. Generally speaking, in a network device 100, there can be one or two main control boards, and two main control boards can form a master-slave relationship. The number of service boards and line cards can be set according to the actual processing requirements of the network device 100 without limitation.

[0050] A vertical switching backplane 3, electrically connected to the data module 2, for processing and forwarding the data uploaded by the data module 2 through a switching chip 30 provided on the vertical switching backplane 3, wherein the setting direction of the vertical switching backplane 3 is parallel to the plane where the first plug interface 13 and the second plug interface 14 are located;

[0051] A detachable top cover 15 is disposed on one side of the second plug-in port 14 of the box 1 , and the vertical switching backplane 3 is disposed in the middle of the box 1 close to one side of the first plug-in port 13 of the box 1 .

[0052] In the network device 100, the vertical switching backplane 3 can be directly fixed to the box body 1. For example, the box body 1 can be provided with supporting feet extending into the box body 1 from the connection between the top plate 10 and the bottom plate 12, the connection between the top plate 10 and the side plate 11, the side plate 11 or the connection between the side plate 11 and the bottom plate 12. The vertical switching backplane 3 is fixed to the supporting feet by screwing and riveting. A backplane bracket parallel to the vertical switching backplane 3 can also be provided in the network device 100, and the vertical switching backplane 3 is fixed to the backplane bracket. It can be set according to actual needs and there is no limitation to this.

[0053] A hollow portion may be provided on the box body 1 as a maintenance port 16, and the maintenance port 16 may be provided on the top plate 10 or the side plate 11, preferably on the top plate 10, and the internal structure of the network device 100 may be exposed through the removable top cover 15, so that the staff can perform maintenance on the interior of the network device 100 by removing the maintenance port 16 revealed by the removable top cover 15, thereby improving the maintenance efficiency of the network device.

[0054] A heat sink may also be provided on the switching chip 30 of the vertical switching backplane 3 to increase the heat dissipation efficiency of the switching chip 30 in the network device 100 .

[0055] Preferably, the vertical switching backplane 3 is arranged in the middle of the network device 100, and is closer to the first plug interface 13 on one side of the data module 2, and the vertical switching backplane 3 can be located at the edge of the maintenance port 16, so that after removing the removable top cover 15, the staff can more comprehensively observe the vertical switching backplane 3 from the maintenance port 16. This arrangement can also leave more operating space for the staff, further improving the maintenance efficiency of the network equipment.

[0056] By setting the switching chip 30 on the vertical switching backplane 3 and electrically connecting the data module 2 to the vertical switching backplane 3 through the corresponding connector, the distance for the signal received and forwarded by the data module 2 to reach the switching chip 30 is shortened, thereby reducing the loss caused by the long signal transmission distance in the network device, improving the signal integrity of the network device, and the signal processing performance of the network device.

[0057] Optionally, the network device 100, such as Figure 1-4 As shown, it also includes:

[0058] A first module frame 4 is provided on one side of the first plug interface 13 of the box 1, and is used to support the data module 2 in the box 1. The first module frame 4 can be embedded in the box 1 and fixed to the box 1 by screwing or riveting. A slideway can be formed on the inner wall of the first module frame 4, and the data module 2 can be pushed into the box 1 of the network device 100 along the slideway;

[0059] The backplane bracket 5 is fixed to one side of the first module frame 4 close to the middle of the box body 1 , and is used to fix the vertical exchange backplane 3 to the middle of the box body 1 .

[0060] Optionally, the first module frame 4, such as Figure 1-4 As shown, including:

[0061] A frame 40, the frame 40 encloses a receiving cavity 41 for receiving the data module 2, the frame 40 may be provided with a screw hole and the like, and fixed to the box 1 with screws, and the slideway may be provided on one side of the frame 40 facing the receiving cavity 41, so as to make the insertion of the data module 2 smoother;

[0062] A heat dissipation cavity 42 is formed between the frame 40 and the box 1. The horizontal dimension of the frame 40 can be slightly smaller than that of the box 1 so that the frame 40 can be tightly fixed in the box 1. The vertical dimension of the frame 40 needs to be smaller than that of the box 1. For example, the frame 40 fits tightly to the bottom plate 12 in the vertical direction, and a part of space can be reserved between the upper side of the frame 40 and the box 1, and this part of space forms the heat dissipation cavity 42.

[0063] A dustproof plate with holes may be provided in the area of ​​the first plug port 13 relative to the heat dissipation cavity 42 to shield the area of ​​the heat dissipation cavity 42 and prevent a large amount of dust from being sucked into the network device 100 .

[0064] Due to the provision of the heat dissipation cavity 42 , the heat dissipation channel of the network device 100 can be enlarged, thereby improving the heat dissipation effect of the network device 100 when performing air cooling or air-liquid mixed cooling.

[0065] In order to reduce the distance between the data module 2 and the switching chip 30, the switching chip 30 is arranged on the vertical switching backplane 3, and due to the transmission of signals, a signal line from the connector to the switching chip 30 needs to be arranged on the vertical switching backplane 3, which requires the vertical switching backplane 3 to have a certain size. Then, arranging the vertical switching backplane 3 in the middle of the network device 100 will block a certain heat dissipation channel and reduce the heat dissipation efficiency of the network device 100.

[0066] In this case, in order to avoid overheating damage to the switching chip 30 of the network device 100 and the logic chip set on the data module 2 due to the failure of heat to be dissipated in time, the vertical switching backplane 3, such as Figure 1-4 As shown, it also includes:

[0067] The main heat dissipation part 31 is attached to the switching chip 30;

[0068] The auxiliary heat dissipation portion 32 is disposed in the heat dissipation cavity 42;

[0069] The heat conducting part 33 has one end connected to the main heat dissipating part 31 , and the other end connected to the auxiliary heat dissipating part 32 .

[0070] The main heat sink 31 and the auxiliary heat sink 32 can use fins in the air cooling method or cold plates in the liquid cooling method, or use a combination of the two. The main heat sink 31 and the auxiliary heat sink 32 can be connected by a metal material with good thermal conductivity. Combined with the structure in the network device 100, the main heat sink 31 is attached to the switching chip 30 to quickly obtain the heat generated by the switching chip 30 with a large heat generation. The auxiliary heat sink 32 is arranged in the heat sink cavity 42. Since the heat sink 42 has a large heat dissipation space, the auxiliary heat sink 32 placed in the heat sink cavity 42 can also have a good heat dissipation effect.

[0071] The heat conducting part 33 between the main heat dissipation part 31 and the auxiliary heat dissipation part 32, one end of the heat conducting part 33 can be locked on the main heat dissipation part 31 by means of a structure such as a screw, so that the heat conducting part 33 can fit tightly with the main heat dissipation part 31. The main heat dissipation part 31 fits on the surface of the switching chip 30 and can extend along the setting direction of the vertical switching backplane 3. The auxiliary heat dissipation part 32 is arranged in the heat dissipation cavity 42, and its plane is orthogonal to the plane where the vertical switching backplane 3 is located. The heat conducting part 33 extends from the main heat dissipation part 31 to the side close to the auxiliary heat dissipation part 32, then bends to extend to the plane where the auxiliary heat dissipation part 32 is located, and is connected to the auxiliary heat dissipation part 32. The connection between the heat conducting part 33 and the main heat dissipation part 31 and the auxiliary heat dissipation part 32 can be connected by screwing or bonding with a thermal conductive material, which can be set according to actual needs, and there is no limitation on this.

[0072] Through the main heat dissipation part 31 , the auxiliary heat dissipation part 32 and the heat conduction part 33 , the heat generated by the switching chip 30 of the vertical switching backplane 3 can be quickly absorbed into the main heat dissipation part 31 , and transferred to the auxiliary heat dissipation part 32 through the heat conduction part 33 to improve the heat dissipation effect.

[0073] Optional, such as Figure 3 , 5 As shown, ventilation holes 34 are provided on the vertical exchange back plate 3 .

[0074] By providing the vents 34 , part of the cold air can pass through the vertical switching backplane 3 and be transferred to one side of the data module 2 , thereby dissipating the heat of the heat generating components on the data module 2 more effectively.

[0075] Optionally, the network device 100, such as Figure 1-4 As shown, it also includes:

[0076] The adapter plate 60 is connected to the vertical switching backplane 3;

[0077] The adapter tray 61 is disposed on the bottom plate 12 of the box body 1 and is used to support the adapter plate 60 .

[0078] The adapter tray 61 can be arranged in the box body 1 and can be fixed on the bottom plate 12 or the top plate 10. Because the adapter plate 60 needs to be connected to the vertical exchange backplane 3, it is necessary to determine the position of the adapter plate 60 in combination with the structure on the vertical exchange backplane 3, so as to determine the position of the adapter tray 61 supporting the adapter plate 60.

[0079] When a power supply is provided in the network device 100 , the adapter plate 60 can be used to realize power distribution for the vertical switching backplane 3 , the data module 2 and other electronic components in the network device 100 .

[0080] Furthermore, the network device 100, such as Figure 1-4 As shown, it also includes:

[0081] The power module 70 is arranged at the second plug interface 14 of the box 1, and is electrically connected to the adapter board 60 through the power board 71, and supplies power to the vertical switching backplane 3 through the adapter board 60. The power board 71 can realize power transmission in the form of power supply cables or bus bars;

[0082] A power supply air guide cover 72, arranged at the air outlet of the power supply module 70;

[0083] The power supply air guide cover 72 includes:

[0084] The collecting portion 72A covers the air outlet of the power module 70;

[0085] The discharge portion 72B is disposed in the heat dissipation cavity 42;

[0086] The transmission portion 72C is connected between the collecting portion 72A and the discharging portion 72B.

[0087] The power module 70 can be pushed into the box body 1 from the second plug interface 14 and connected to the power board 71 disposed in the box body 1. The power board 71 is connected to the adapter board 60, and power is supplied in the order of the power module 70, the power board 71, the adapter board 60, the vertical switching backplane 3 and the data module 2.

[0088] Since the power module 70 also generates heat during operation, when the vertical switching backplane 3 is arranged in the middle of the network device 100, in order to improve the heat dissipation efficiency of the power module 70, a heat dissipation channel can be separately provided for the power module 70. That is, the collecting portion 72A, the transmission portion 72C and the discharge portion 72B formed by the sheet metal material are used to finally discharge the heat generated by the power module 70 to the outside through the heat dissipation cavity 42.

[0089] In order to prevent dust from entering the network device 100 , optionally, a dustproof plate 43 is provided at a position of the heat dissipation cavity 42 close to the first plug port 13 .

[0090] Optionally, the network device 100, such as Figure 1-4 As shown, it also includes:

[0091] The fan module 80 is disposed at the second plug interface 14 of the box 1 and is electrically connected to the power board 71 through the fan board 81;

[0092] The second module frame 9 has a power cavity for accommodating the power module 70 and a fan cavity for accommodating the fan module 80 formed therein.

[0093] By disposing the second module frame 9 , the structure inside the network device 100 is made more stable, and the installation efficiency of the network device 100 is further improved.

[0094] The implementation process of the functions and effects of each module in the above-mentioned device is specifically described in the implementation process of the corresponding steps in the above-mentioned method, which will not be repeated here.
