The chassis of the frame equipment is placed in a rack provided by an operator, and the rack usually has fixed dimension specifications of 600 × 800, 600 × 1000, 600 × 1100, 600 × 1200mm and the like. The cabinets are laid out in advance along with the construction of the machine room, and the cabinets provided by equipment suppliers are required to be matched with the cabinets provided by operators. However, with the rapid increase of the capacity of the frame-type device and the application of standard interfaces such as 100GE and 400GE, the physical link rate is increased to 56Gbps, the application and the number of large-sized switching chips are increased, the design difficulty of the wire clamping plate and the switching network plate is higher and higher, and a larger space for a printed circuit board, heat dissipation and fiber output is required. The contradiction between the orthogonal architecture and the depth of the frame type equipment is more and more prominent, how to reduce the depth of the frame type equipment and improve the space utilization rate of a machine room is achieved, and the method has important significance for improving the product competitiveness of the frame type equipment.

Fig. 2 is a schematic structural diagram of a frame device provided in an embodiment of the present application. Referring to fig. 2, the block type apparatus includes: line card board 1, exchange screen board 2, first connector 31 and second connector 32.

The cable card board 1 is connected to a first end of a first connector 31, the switching board 2 is connected to a first end of a second connector 32, and a second end of the first connector 31 is connected to a second end of the second connector 32. The plane of the cable card board 1, the plane of the exchange network board 2 and the first plane are mutually vertical in pairs. The exchange network board 2 comprises a first part 21 and a second part 22, the cable card board 1 and the first part 21 are positioned in the space on one side of the first plane, and the second part 22 is positioned in the space on the other side of the first plane.

It should be noted that the cable card board 1 is used to provide an actual service interface to receive service data transmitted by an external data source. The switching network board 2 is used for data exchange between the line card boards 1, that is, one line card board 1 can transmit data to another line card board 1 through the switching network board 2.

In addition, the quantity of line cardboard 1 can be one or more, and when the quantity of line cardboard 1 was a plurality of, a plurality of line cardboard 1 can parallel arrangement, and the plane that each line cardboard 1 was located in this a plurality of line cardboard 1 is parallel to each other promptly. Similarly, the number of the switching network boards 2 may be one or more, and when the number of the switching network boards 2 is plural, the plural switching network boards 2 may be arranged in parallel, that is, the planes of the plural switching network boards 2 are parallel to each other.

Further, when the number of the cable card boards 1 is plural and the number of the exchange network boards 2 is also plural, the number of the first connectors 31 may be plural and the number of the second connectors 32 may be plural. In this case, the plurality of first connectors 31 may be arranged in a plurality of rows and columns, and the plurality of second connectors 32 may be arranged in a plurality of rows and columns. At this time, one wire clamping board 1 of the plurality of wire clamping boards 1 may be connected to the first end of each first connector 31 of a row of first connectors 31, one switching board 2 of the plurality of switching boards 2 may be connected to the first end of each second connector 32 of a column of second connectors 32, and the second ends of the plurality of first connectors 31 and the second ends of the plurality of second connectors 32 are connected in a one-to-one manner.

For example, as shown in fig. 2, the plurality of first connectors 31 and the plurality of second connectors 32 are each arranged in a plurality of rows and columns, the positions of the plurality of first connectors 31 correspond to the positions of the plurality of second connectors 32 one by one, and the second end of each of the plurality of first connectors 31 is connected to the second end of one of the second connectors 32 corresponding to the position thereof. Each wire clamping plate 1 in a plurality of wire clamping plates 1 is connected with the first end of one row of first connectors 31 in a plurality of rows of first connectors 31, and a plurality of wire clamping plates 1 are transversely arranged in sequence after being connected with a plurality of rows of first connectors 31, each exchange screen plate 2 in a plurality of exchange screen plates 2 is connected with the first end of one column of second connectors 32 of a plurality of columns of second connectors 32, and a plurality of exchange screen plates 2 are vertically arranged in sequence after being connected with a plurality of columns of second connectors 32.

It should be noted that the plane where the cable card board 1 is located, the plane where the switching network board 2 is located, and the first plane are perpendicular to each other two by two. Thus, the wire clamping board 1 and the switch board 2 can form an orthogonal structure to control the length of the wire between the wire clamping board 1 and the switch board 2 to be the shortest.

In addition, the second end of the first connector 31 and the second end of the second connector 32 may be directly connected, for example, the first connector 31 may be a bow connector, and the second connector 32 may be a curved female connector, in which case the first connector 31 and the second connector 32 may be directly connected. Or, the second end of the first connector 31 and the second end of the second connector 32 may be connected by a back plate, in this case, the frame device may further include a back plate, the second end of the first connector 31 is connected to one side plate surface of the back plate, the second end of the second connector 32 is connected to the other side plate surface of the back plate, and at this time, the first plane is a plane where the plate surface of the back plate is located. Alternatively, referring to fig. 3, the frame device may further include a cable, and the second end of the first connector 31 and the second end of the second connector 32 may be connected by the cable, so that the data transmission rate between the cable card board 1 and the switch board 2 may be increased.

Furthermore, both one side face and the other side face of backplate can be provided with the connector, and when the second end of first connector 31 was connected with one side face of backplate, the second end of first connector 31 can be connected with the connector that sets up on one side face of backplate. When the second end of the second connector 32 is connected to the other side of the backboard, the second end of the second connector 32 may be connected to the connector provided on the other side of the backboard. Certainly, in practical applications, the second end of the first connector 31 may also be connected to one side of the backboard through other manners, and the second end of the second connector 32 may also be connected to the other side of the backboard through other manners, which is not limited in this embodiment of the application.

It should be noted that the switching net plate 2 includes a first part 21 and a second part 22, and the depth of the first part 21 may be less than or equal to the depth of the cable clamping plate 1. The height of the first portion 21 and the height of the second portion 22 may be the same or different, e.g. the height of the first portion 21 may be smaller than the height of the second portion 22. For example, as shown in fig. 4, the exchange mesh plate 2 may have a convex structure, wherein the convex portion in the exchange mesh plate 2 may be the first portion 21, and the other portion except the convex portion may be the second portion 22.

In addition, the first part 21 of the wire card board 1 and the exchange network board 2 is positioned in one side space of the first plane, and the second part 22 of the exchange network board 2 is positioned in the other side space of the first plane. For example, as shown in fig. 2, when the number of the wire clamping plates 1 is at least two, the first part 21 may be located in a gap between two adjacent wire clamping plates 1 of the at least two wire clamping plates 1, and thus, the wire clamping plates 1 and the first part 21 may be located in a space on one side of the first plane. In addition, when the second end of the first connector 31 and the second end of the second connector 32 are connected through the back plate, an opening may be formed in the back plate, and the first portion 21 may pass through the opening to be located in a space on one side of the first plane with the wire card board 1.

In the embodiment of the application, line cardboard 1 and exchange otter board 2's first part 21 shared space, under this condition, the quick-witted case depth of frame equipment only need be greater than the degree of depth sum of the degree of depth of line cardboard 1 and exchange otter board 2's second part 22, compare in the relevant art the quick-witted case depth of frame equipment need be greater than the degree of depth sum's of line cardboard and exchange otter board scheme, the quick-witted case depth of frame equipment can effectively be reduced to the embodiment of the application, make the quick-witted case depth can be by big diminishing, thereby can the less rack of adaptation degree of depth.

For example, the size of the cabinet of the frame type device provided by the embodiment of the present application is as shown in fig. 5, the switching board 2 is in a convex structure, and the first portion 21 of the switching board 2 is a protruding portion, and the protruding portion shares a space with the wire clamping board 1. The depth of the cable-card board 1 (first depth) + the total depth of the first connector 31 and the second connector 32 (second depth) + the depth of the second part 22 of the switching net 2 (depth 2) is the depth of the cabinet of the frame type device. The depth of the case of the conventional frame type device includes the depth (depth 1) of the first portion 21, so the depth 1 is the depth saved by the present application. So, can effectively reduce the quick-witted case degree of depth of frame equipment to can realize the installation of shallow rack, save computer lab overall arrangement space, can arrange more equipment in the computer lab, improve the utilization ratio of computer lab, bring great competition advantage for the product simultaneously.

The switch Board 2 may include a plurality of electronic devices, such as a switch chip, a power brick, a Central Processing Unit (CPU) subsystem, and the like, and the switch Board 2 may further include a Printed Circuit Board (PCB), and these electronic devices may be assembled through the PCB. The exchange chip is used for realizing data exchange among the wire clamping plates 1, the power brick is used for providing electric energy for the exchange network plate 2, the CPU small system is used for managing the exchange network plate 2, and the PCB is used for providing a physical carrier for a high-speed link of the exchange network plate 2. The electronic devices may include a heat generating device, which may be a device that generates relatively large heat and has relatively high temperature during operation, for example, the heat generating device may be a switching chip. In order to dissipate heat of the heat generating device, the heat generating device may be disposed in the first portion 21. Further, if a plurality of heat generating devices are included in the switching board 2, at least one of the plurality of heat generating devices may be disposed in the first section 21, and the other heat generating devices except the at least one heat generating device may be disposed in the second section 22 in a region adjacent to the first section 21. Also, other electronic devices than the heat generating device in the switching net 2 may be provided in the second section 22.

For example, as shown in fig. 4, the switch board 2 includes a PCB, two switch chips, a power brick and a CPU subsystem, and the two switch chips, the power brick and the CPU subsystem are all loaded on the PCB. One of the two switch chips may be provided in the first portion 21, i.e. one switch chip may be included in the first portion 21. Another switch chip is arranged in the second part 22 in an area adjacent to the first part 21 and the power brick and the CPU subsystem are also arranged in the second part 22, i.e. the second part 22 comprises one switch chip, power brick and CPU subsystem.

In this case, in order to dissipate heat generated by the heat generating devices in the switching network board 2, there may be three kinds of heat dissipation structures as follows.

The first heat dissipation structure: as shown in fig. 6, the block device may further include a first fan 4, and the heat generating device may be included in the first portion 21. The second portion 22 is located between the first plane and the second plane, the second portion 22 is located in a space on one side of the second plane, the first fan 4 is located in a space on the other side of the second plane, and the first portion 21 is located between the air inlet of the frame device and the second portion 22.

It should be noted that the first fan 4 is a device that utilizes the cooling principle of air convection and negative pressure ventilation, and air from the air inlet to the first fan 4 can form convection blowing.

In addition, in the embodiment of the present application, the air inlet is arranged in front, the first fan 4 is arranged in back, and then the first portion 21 faces the air inlet, so that the heat generating devices in the first portion 21 can be arranged at the optimal position of the air duct. In this case, the air duct is from the air inlet to the first portion 21, then from the first portion 21 to the second portion 22, and finally from the second portion 22 to the first fan 4. That is, the heat dissipation channel of the exchange network board 2 is a heat dissipation channel independent of the cable card board 1, specifically, the airflow entering from the air inlet directly reaches the first portion 21, then passes through the first portion 21 to dissipate heat of the heat generating device in the first portion 21, then passes through the second portion 22 to dissipate heat of the electronic device in the second portion 22, and finally is exhausted by the first fan 4. Because the heating device in the first part 21 is closer to the air inlet, the heat dissipation of the heating device is more facilitated, so that the heat dissipation efficiency can be improved, the reliability of the frame type equipment can be improved, and the energy can be saved more.

Further, the position where the first portion 21 meets the second portion 22 may be any position of the second portion 22.

In this case, the air duct is from the air inlet to the first portion 21, then from the first portion 21 to the second portion 22, and finally from the second portion 22 to the first fan 4. That is, the heat dissipation channel of the exchange network board 2 is a heat dissipation channel independent of the cable card board 1, specifically, the airflow entering from the air inlet directly reaches the first portion 21, then passes through the first portion 21 to dissipate heat of the heat generating device in the first portion 21, then passes through the second portion 22 to dissipate heat of the electronic device in the second portion 22, and finally is exhausted by the first fan 4. Because the heating device in the first part 21 is closer to the air inlet, the heat dissipation of the heating device is more facilitated, so that the heat dissipation efficiency can be improved, the reliability of the frame type equipment can be improved, and the energy can be saved more.

In this case, air is introduced from an air inlet in the middle of the cabinet, passes through the first portion 21 to reach the second portion 22, and then reaches the first fan 4 from both sides of the second portion 22 to be discharged. Thereby form the radiating passage of air inlet, quick-witted case rear side both ends air-out in the middle of the quick-witted case front side, and generate heat the device overall arrangement near the air intake, so, can further improve the radiating efficiency of this frame equipment.

For another example, when only one of the two fan fixing structural members 5 is provided with the first fan 4, as shown in fig. 8, the position where the first portion 21 meets the second portion 22 may be a position in the second portion 22 close to the other fan fixing structural member 5. In this case, air is introduced from an air inlet at the lower side (or the upper side) of the cabinet, passes through the first portion 21, reaches the second portion 22, and then reaches the first fan 4 located in the upper fan fixing structural member 5 (or the lower fan fixing structural member 5) from the second portion 22 to be discharged.

The air duct is now from the second fan 6 to the first section 21 and then from the first section 21 to the second section 22. That is, the heat dissipation channel of the exchange network board 2 is a heat dissipation channel independent of the cable card board 1, specifically, the airflow generated by the second fan 6 directly reaches the first portion 21, then passes through the first portion 21 to dissipate heat of the heat generating device in the first portion 21, and then passes through the second portion 22 to dissipate heat of the electronic device in the second portion 22. Since the heat generating device in the first portion 21 is closer to the second fan 6, heat dissipation of the heat generating device is more facilitated, and thus heat dissipation efficiency can be improved, so that reliability of the frame type apparatus can be improved and energy can be more saved.
