Description

Technical Field

[0001] The utility model relates to the field of communication technology, and in particular to a heat dissipation framework, a plug-in frame, a network device and a communication system. Background Art

[0002] Plug-in frames are mainly used in optical access central office equipment, switches, data centers, servers and other network equipment for processing and distributing data or signals.

[0003] With the development of the era of massive data, the demand for high-bandwidth transmission and high-performance computing continues to rise. After the frame is connected to the network equipment, the frame evolves as the workload of the network equipment continues to change. As the frame evolves, the network is gradually upgraded, the power consumption of the frame gradually increases, and the required heat dissipation capacity requirements are gradually increased. A heat dissipation architecture that can match the evolution of the frame is urgently needed to ensure heat dissipation requirements while reducing costs. Utility Model Content

[0004] The purpose of this application is to provide a heat dissipation architecture, a plug-in frame, a network device and a communication system, which can ensure the heat dissipation requirements before and after the network upgrade while reducing the cost.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] According to a first aspect of an embodiment of the present application, a heat dissipation architecture is provided, which includes: a heat dissipation frame, at least one limiter and at least one fan box. The heat dissipation frame has a heat dissipation cavity. The heat dissipation frame includes a first cavity wall and a second cavity wall arranged opposite to each other. A first vent connected to the heat dissipation cavity is provided on the heat dissipation frame. The limiter is located in the heat dissipation cavity, and the limiter is arranged on the first cavity wall. A first accommodating cavity is formed between a side surface of the limiter facing away from the first cavity wall and the second cavity wall. The limiter divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the limiter; the fan box is located in the heat dissipation cavity, and the air outlet of the fan box faces the first vent. The fan box slides with the limiter along the extension direction of the limiter.

[0007] As can be seen from the above, the heat dissipation frame of the heat dissipation architecture has a heat dissipation cavity, and the fan box can be arranged in the heat dissipation cavity. The air outlet of the fan box faces the first vent provided on the heat dissipation frame, so that the air outlet of the fan box and the first vent can ventilate each other to achieve heat dissipation. In addition, the heat dissipation architecture also includes a limiter, which is arranged on the first cavity wall, and a side surface of the limiter facing away from the first cavity wall forms a first accommodating cavity with the second cavity wall. In addition, the limiter divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the limiter. At this time, the fan box can be arranged in the first accommodating cavity. Alternatively, the fan box can also be arranged in the second accommodating cavity or the third accommodating cavity. Alternatively, a part of the fan box can be arranged in the second accommodating cavity, and the other part can be arranged in the third accommodating cavity. When the heat dissipation demand is low, the heat dissipation architecture can set a fan box in the first accommodating cavity. At this time, in the direction parallel to the first cavity wall and perpendicular to the extension direction of the limiter, the limiter will not hinder the setting of the fan box in the first accommodating cavity, and the size of the fan box can be larger, thereby ensuring the heat dissipation demand at this time. Compared with setting multiple fan boxes, the cost of setting a fan box is lower, thereby reducing the cost before the network upgrade. However, when the heat dissipation architecture only includes one fan box, when the fan box fails or needs maintenance, the fan box needs to be stopped and taken out for repair and maintenance. Because the heat dissipation architecture temporarily loses its heat dissipation function, the heat dissipation architecture cannot meet the higher heat dissipation demand at this time. After the network upgrade, when the heat dissipation demand is high, the heat dissipation architecture can set two independent fan boxes in the first accommodating cavity and the second accommodating cavity. When one of the fan boxes needs to be repaired or maintained, the other fan box continues to work, ensuring that the heat dissipation architecture will not completely lose its heat dissipation function to meet the higher heat dissipation demand. Moreover, the power consumption of the two fan boxes can be adjusted separately in combination with the heat dissipation demand of different regions to ensure the heat dissipation demand while optimizing the comprehensive power consumption. This is to ensure heat dissipation requirements before and after network upgrades while reducing costs.

[0008] In some embodiments of the present application, the at least one stopper includes a first stopper, which divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the first stopper; the at least one fan box includes a first fan box and a second fan box. The first fan box is arranged in the second accommodating cavity, and a side surface of the first fan box facing the third accommodating cavity slides with the first stopper. The second fan box is arranged in the third accommodating cavity, and a side surface of the second fan box facing the second accommodating cavity slides with the first stopper. Among them, there is a first gap between the first fan box and the second fan box, and the first stopper is located in the first gap. As can be seen from the above, the first stopper is located in the first gap between the first fan box and the second fan box, and the first fan box and the second fan box both slide with the first stopper. At this time, in a direction perpendicular to the extension direction of the first limiter and parallel to the first cavity wall, the first limiter can limit the first fan box and the second fan box respectively, and both the first fan box and the second fan box can only slide along the extension direction of the first limiter, so that the first limiter can guide the sliding of the first fan box and the second fan box respectively, so as to ensure that both the first fan box and the second fan box can be installed in the expected position.

[0009] In some embodiments of the present application, the at least one stopper may further include a second stopper, the second stopper is located in the third accommodating chamber, and the second stopper divides the third accommodating chamber into a fourth accommodating chamber and a fifth accommodating chamber along the extension direction of the second stopper. The second fan box is located in the fourth accommodating chamber, and the side surface of the second fan box facing the fifth accommodating chamber slides with the second stopper. The at least one fan box also includes a third fan box, the third fan box is located in the fifth accommodating chamber, and the side surface of the third fan box facing the fourth accommodating chamber slides with the second stopper. Wherein, there is a second gap between the second fan box and the third fan box, and the second stopper is located in the second gap. As can be seen from the above, the first stopper and the second stopper divide the heat dissipation chamber into a second accommodating chamber, a fourth accommodating chamber and a fifth accommodating chamber along the extension direction of the first stopper and the second stopper. The second fan box is arranged in the fourth accommodating chamber, and is limited and guided by the second stopper, and the second stopper guides the sliding of the second fan box. The third fan box is arranged in the fifth accommodating cavity and is limited and guided by the second limiter, which guides the sliding of the third fan box to ensure that when multiple fan boxes need to be replaced after the network upgrade, the second fan box and the third fan box can be installed in the expected position.

[0010] In some embodiments of the present application, the at least one stopper may include a first stopper, which divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the first stopper. The at least one fan box may include a first fan box and a second fan box. The first fan box is arranged in the second accommodating cavity. The first fan box is provided with a first slide groove on the side facing the first cavity wall. The first stopper is located in the first slide groove and cooperates with the first slide groove. The second fan box is arranged in the third accommodating cavity. The side surface of the second fan box facing the second accommodating cavity is slidably cooperated with the stopper. At this time, the first stopper is located in the first slide groove of the first fan box, and the first stopper cooperates with the first slide groove, so that the first fan box can only slide along the extension direction of the first stopper. So that the first stopper limits and guides the first fan box to ensure that the first fan box can be installed in the expected position. In addition, the first stopper is located in the first slide groove. At this time, the gap between the surface of the first fan box facing the second fan box and the surface of the second fan box facing the first fan box can be small or even no gap. At this time, the space occupied by the first fan box and the second fan box in the heat dissipation cavity is large, thereby improving the space utilization rate in the heat dissipation cavity.

[0011] In some embodiments of the present application, the surface of the first fan box facing the second fan box abuts against the surface of the second fan box facing the first fan box. At this time, there is no other gap between the first fan box and the second fan box except for the first slide groove for accommodating the first limiter, which further increases the space occupied by the first fan box and the second fan box in the heat dissipation cavity, thereby further improving the space utilization rate in the heat dissipation cavity.

[0012] In some embodiments of the present application, the at least one stopper includes a first stopper, and the first stopper divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the first stopper. The at least one fan box includes a first fan box and a second fan box. The first fan box is arranged in the second accommodating cavity, and a first recessed portion is arranged on the side of the first fan box facing the first cavity wall. The second fan box is arranged in the third accommodating cavity, and a second recessed portion is arranged on the side of the second fan box facing the first cavity wall. The first recessed portion and the second recessed portion jointly form a second slide groove. The first stopper is located in the second slide groove and cooperates with the second slide groove. Similar to the embodiment in which the first fan box is provided with a first slide groove on the side facing the first cavity wall. At this time, the first stopper is located in the second slide groove formed by the first recessed portion of the first fan box and the second recessed portion of the second fan box, and the first stopper cooperates with the second slide groove. The first limiting member can guide the sliding of the first fan box and the second fan box respectively, so as to ensure that the first fan box and the second fan box can be installed in the expected positions.

[0013] In some embodiments of the present application, the at least one stopper may include a first stopper and a second stopper. The first stopper divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the first stopper. The second stopper is located in the third accommodating cavity, and the second stopper divides the third accommodating cavity into a fourth accommodating cavity and a fifth accommodating cavity along the extension direction of the second stopper. The at least one fan box may include a first fan box and a second fan box. The first fan box is arranged in the second accommodating cavity and the fourth accommodating cavity, between the first stopper and the second cavity wall, and the first fan box and the first stopper slide in cooperation with the surface of the second cavity wall. The second fan box is arranged in the fourth accommodating cavity and the fifth accommodating cavity, between the second stopper and the second cavity wall, and the second fan box and the second stopper slide in cooperation with the surface of the second cavity wall. As can be seen from the above, a part of the first fan box is arranged in the second accommodating cavity, and the other part is arranged in the fourth accommodating cavity, and slides with the first stopper. At this time, the first fan box can slide on the surface of the first stopper toward the second cavity wall, thereby realizing the installation and removal of the first fan box. In addition, a portion of the second fan box is arranged in the fourth accommodating cavity, and the other portion is arranged in the fifth accommodating cavity, and is slidably matched with the second stopper. Similarly, the second fan box can slide on the surface of the second stopper toward the second cavity wall, thereby realizing the installation and removal of the second fan box.

[0014] In some embodiments of the present application, a third slide is provided on the side of the first fan box facing the first cavity wall. The first stopper is located in the third slide and cooperates with the third slide. A fourth slide is provided on the side of the second fan box facing the first cavity wall. The second stopper is located in the fourth slide and cooperates with the fourth slide. As can be seen from the above, the first stopper is located in the third slide of the first fan box and cooperates with the third slide. At this time, in a direction perpendicular to the extension direction of the first stopper and parallel to the first cavity wall, the first stopper can limit the first fan box, so that the first stopper can guide the sliding of the first fan box. Similarly, the second stopper is located in the fourth slide of the second fan box and cooperates with the fourth slide. The second stopper can also limit and guide the second fan box, so that the second stopper can guide the sliding of the second fan box. To ensure that both the first fan box and the second fan box can be installed in the expected position.

[0015] In some embodiments of the present application, the fan box is disposed in the first accommodation cavity. Before the network is upgraded, only one fan box can be installed in the heat dissipation cavity, thereby meeting the low heat dissipation requirement before the network upgrade and reducing the cost.

[0016] In some embodiments of the present application, the fan box may include a first part and a second part. The first part is arranged in the first accommodating cavity. A fifth slide groove is arranged on the side of the second part facing the first cavity wall, and the stopper is located in the fifth slide groove and cooperates with the fifth slide groove. At this time, the second part of the fan box is located between the side surface of the stopper facing away from the first cavity wall and the first cavity wall. Compared with setting the entire fan box in the first accommodating cavity, the fan box occupies a larger space in the heat dissipation cavity, thereby improving the space utilization rate in the heat dissipation cavity.

[0017] In some embodiments of the present application, the fan box may include a first fan assembly and a second fan assembly, and the first fan assembly and the second fan assembly are connected on a side facing away from the heat dissipation cavity. A third gap is provided between the first fan assembly and the second fan assembly. The stopper is located in the third gap. At this time, the stopper is located in the third gap between the first fan assembly and the second fan assembly, and the stopper does not hinder the first fan assembly and the second fan assembly from being installed in the heat dissipation cavity. This ensures that before the network is upgraded, only one larger fan box can be installed in the heat dissipation cavity to meet the low heat dissipation requirements before the network upgrade.

[0018] According to a second aspect of an embodiment of the present application, a heat dissipation structure is provided, which includes a heat dissipation frame and at least one limit member. The heat dissipation frame has a heat dissipation cavity. The heat dissipation frame includes a first cavity wall and a second cavity wall that are arranged opposite to each other. A first vent connected to the heat dissipation cavity is provided on the heat dissipation frame. The limit member is located in the heat dissipation cavity, and the limit member is arranged on the first cavity wall. A first accommodating cavity is formed between a side surface of the limit member that faces away from the first cavity wall and the second cavity wall. The limit member divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the limit member. The above-mentioned heat dissipation structure has the same technical effect as the heat dissipation structure provided in the aforementioned embodiment, which will not be repeated here.

[0019] In a third aspect of an embodiment of the present application, a heat dissipation architecture is provided, which includes a heat dissipation frame and at least one stopper. The heat dissipation frame has a heat dissipation cavity. The heat dissipation frame includes a first cavity wall and a second cavity wall arranged opposite to each other. The heat dissipation frame is provided with a first vent connected to the heat dissipation cavity. The stopper is located in the heat dissipation cavity. The stopper is detachably connected to the first cavity wall, and the stopper divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the stopper. As can be seen from the above, the stopper is detachable from the first cavity wall. Before the network is upgraded, when the heat dissipation demand is low, after the stopper is removed from the first cavity wall, a larger fan box can be installed in the heat dissipation cavity. After the network is upgraded, when the heat dissipation demand is high, after the stopper is installed on the first cavity wall, the stopper can divide the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity, and two independent fan boxes can be set in the second accommodating cavity and the third accommodating cavity, respectively, to ensure that when the fan box is repaired or maintained, it can be carried out one by one to ensure that at least one fan box is in working condition to meet the heat dissipation demand. This is to ensure heat dissipation requirements before and after network upgrades while reducing costs.

[0020] In a fourth aspect of the embodiments of the present application, a heat dissipation structure is provided, which includes a heat dissipation frame, at least one stopper and a fan box. The heat dissipation frame has a heat dissipation cavity. The heat dissipation frame includes a first cavity wall and a second cavity wall arranged opposite to each other. The heat dissipation frame is provided with a first vent connected to the heat dissipation cavity. The stopper is located in the heat dissipation cavity. The first end of the stopper is fixedly connected to the first cavity wall, and the second end of the stopper is connected to the second cavity wall. The stopper divides the heat dissipation cavity into a second accommodating cavity and a third accommodating cavity along the extension direction of the stopper. The fan box is located in the heat dissipation cavity, and the fan box includes a first fan assembly and a second fan assembly. The first fan assembly and the second fan assembly are connected on one side away from the heat dissipation cavity, and a third gap is provided between the first fan assembly and the second fan assembly. The stopper is located in the third gap. At this time, the first end of the stopper is fixedly connected to the first cavity wall, and the second end of the stopper is connected to the second cavity wall. The stopper is fixedly connected to the second cavity wall, and the fixation of the stopper is relatively reliable, thereby ensuring the connection stability between the stopper and the heat dissipation frame. In addition, the limiter is located in the third gap between the first fan assembly and the second fan assembly. The limiter will not hinder the first fan assembly and the second fan assembly from being installed in the heat dissipation cavity. This ensures that before the network upgrade, only one larger fan box can be installed in the heat dissipation cavity to meet the low heat dissipation requirements before the network upgrade. After the network upgrade, two independent fan boxes can be replaced and installed in the second accommodating cavity and the third accommodating cavity respectively to ensure that when the fan boxes are repaired or maintained, they can be repaired one by one to ensure that at least one fan box is in working condition to meet the heat dissipation requirements. This achieves the purpose of ensuring heat dissipation requirements before and after the network upgrade while reducing costs.

[0021] The fifth aspect of the embodiments of the present application provides a plug-in frame, which includes the heat dissipation architecture described in any of the above embodiments, and the plug-in frame also includes a frame and a plurality of single boards. The heat dissipation architecture and the single board are both arranged in the frame. Each single board is located on the same side of the heat dissipation architecture, and there is a heat dissipation gap between adjacent single boards, and the heat dissipation gap is connected to the first vent. As can be seen from the above, the heat dissipation gap is connected to the first vent. Exemplarily, the heat dissipation architecture sucks air into the heat dissipation gap through the first vent, and then causes the gas at the heat dissipation gap to flow to the first vent to reduce the temperature in the heat dissipation gap. Alternatively, the heat dissipation architecture supplies air to the heat dissipation gap through the first vent, thereby causing the gas in the heat dissipation gap to flow, thereby taking away the heat from the heat dissipation gap to achieve the heat dissipation function. In addition, the above plug-in frame also has the same technical effect as the heat dissipation architecture provided in any of the above embodiments, which will not be repeated here.

[0022] In a sixth aspect of the embodiments of the present application, a network device is provided, the network device comprising one or more subracks. The above network device has the same technical effects as the subracks provided in the above embodiments, which will not be described in detail here.

The above-mentioned communication system has the same technical effect as the plug-in frame provided in the above-mentioned embodiment, which will not be described in detail here.

[0062] The present application embodiment provides a communication system 01, such as Figure 1 As shown, the communication system 01 may include a network device 02 and a first access device 03 connected to the network device 02. The first access device 03 may send a signal to the network device 02, and the network device 02 processes or stores the received signal. Alternatively, the network device 02 may send a signal to the first access device 03 to implement signal exchange between the network device 02 and the first access device 03.

[0063] Continue as Figure 1 As shown, the communication system 01 may also include a plurality of second access devices 04 connected to the network device 02. Similar to the first receiving device 03 described above, the second access device 04 and the network device 02 may also exchange signals. Exemplarily, the network device 02 may receive a signal sent by the first access device 03, and after processing and distribution, send the signal to different second access devices 04. Alternatively, the network device 02 may receive a signal sent by the second access device 04 and send it to the first access device 03.

[0064] The above embodiment Figure 1 As shown, a communication system 01 includes 1 network device 02, 1 first access device 03 and 2 second access devices 04 as an example. In other embodiments of the present application, the number of network devices 02, first access devices 03 and second access devices 04 can be other numbers.

[0065] In addition, the above-mentioned network device 02 may be an optical access central office device, a switch, a data center, a server, etc. For the sake of convenience, the following description will be given by taking the network device 02 as an optical access central office device as an example.

[0066] like Figure 2As shown, the network device 02 of the communication system 01 is an optical access central office device. At this time, in some embodiments of the present application, the first access device 03 can be a central computer room or a base station, and the second access device 04 can be an optical network terminal (Optical Network Terminal, ONT) or an optical network unit (Optical Network Unit, ONU). The optical access central office device includes a plug-in frame 10 and a plurality of distribution frames 20. The plug-in frame 10 is connected to the first access device 03 and performs optical signal exchange. At the same time, the plug-in frame 10 is connected to the distribution frame 20 and performs optical signal exchange. Therefore, after the first access device 03 sends the optical signal to the plug-in frame 10, it is distributed to different distribution frames 20 through the plug-in frame 10, and then distributed to different second access devices 04 through different distribution frames 20. Alternatively, the second access device 04 sends the optical signal to the plug-in frame 10 through the distribution frame 20, and the plug-in frame 10 processes and sends it to the first access device 03. To complete the transmission of the optical signal.

[0067] The above embodiment Figure 2 As shown, a communication system 01 includes one optical access central office device, one first access device 03 and two second access devices 04, and the optical access central office device includes one plug-in frame 10 and two patch panels 20. In other embodiments of the present application, the number of optical access central office devices, first access devices 03 and second access devices 04 can be other numbers. The number of plug-in frames 10 and patch panels 20 can also be other numbers.

[0068] Based on this, in some embodiments of the present application, the above-mentioned plug-in frame 10 is as follows Figure 3A As shown, it may include a heat dissipation structure 11, a frame 12, and multiple single boards 13. The heat dissipation structure 11 and the single boards 13 may be arranged in the frame 12. The frame 12 can limit the heat dissipation structure 11 and the single boards 13 and play a protective role. Multiple single boards 13 are located on the same side of the heat dissipation structure 11, and there is a heat dissipation gap 14 between adjacent single boards 13. When the single board 13 is working, heat is generated around the single board 13 and dissipated into the heat dissipation gap 14. At this time, the heat dissipation structure 11 inhales or delivers air to the heat dissipation gap 14, thereby causing the gas in the heat dissipation gap 14 to flow, thereby taking away the heat of the heat dissipation gap 14, and thereby reducing the temperature around the single board 13. Finally, the heat dissipation of the plug-in frame 10 is completed.

[0069] Exemplarily, the heat dissipation architecture 11 may be as follows: Figure 4A As shown, the heat dissipation structure 11 is arranged above the single board 13. Alternatively, the heat dissipation structure 11 can also be as follows Figure 4B As shown, the heat dissipation structure 11 is arranged below the single board 13. Alternatively, the heat dissipation structure 11 can also be as follows Figure 4C As shown, the heat dissipation structure 11 is arranged on the right side of the single board 13. Alternatively, the heat dissipation structure 11 can also be as follows Figure 4DAs shown, the heat dissipation structure 11 is arranged on the left side of the single board 13. Alternatively, the heat dissipation structure 11 can also be as follows Figure 4E As shown, the heat dissipation structure 11 is arranged on the front side of the single board 13. Alternatively, the heat dissipation structure 11 can also be as Figure 4F The arrangement is shown on the rear side of the single plate 13 .

[0070] Furthermore, if Figure 3C or Figure 3D As shown, the above-mentioned plug-in frame 10 may also include a backplane 15 and at least one connector 16. A cable group (not shown in the figure) is arranged on the backplane 15, and each single board 13 is connected to the cable group. Signals are exchanged and transmitted between different single boards 13 through the cable group. The connector 16 is arranged on the backplane 15, and one end of the connector 16 is electrically connected to the cable group, and the other end is electrically connected to the heat dissipation structure 11. A signal is sent to the connector 16 through the cable group, and then the connector 16 sends the signal to the heat dissipation structure 11, thereby adjusting the working power of the heat dissipation structure 11. In addition, the cable group is also electrically connected to an external power supply, and the external power supply supplies power to the single board 13 and the heat dissipation structure 11 through the cable group. Ensure that the single board 13 and the heat dissipation structure 11 can work normally.

[0071] On this basis, in some embodiments of the present application, the heat dissipation architecture 11 can be as follows: Figure 5A The heat dissipation frame 111 includes a heat dissipation cavity 1111. The heat dissipation frame 111 is provided with a first vent 1112 connected to the heat dissipation cavity 1111. The first vent 1112 is connected to the heat dissipation gap 14 (such as Figure 3A As shown in the figure, the first vent 1112 is connected to the heat dissipation cavity 1111, and the first vent 1112 is also connected to the heat dissipation cavity 1111. Therefore, heat exchange can be performed between the first vent 1112, the heat dissipation gap 14 and the heat dissipation cavity 1111 to complete the heat dissipation of the insertion frame 10.

[0072] Continue as Figure 5A As shown, the heat dissipation frame 111 may include a first cavity wall 1113 and a second cavity wall 1114 disposed opposite to each other. The heat dissipation frame 111 may include at least one stopper 112 disposed in the heat dissipation cavity 1111, and the stopper 112 is disposed on the first cavity wall 1113. Figure 5B As shown, the limiting member 112 (such as Figure 5A The first accommodating cavity 11111 is formed between a side surface facing away from the first cavity wall 1113 and the second cavity wall 1114. Because the stopper 112 is located in the heat dissipation cavity 1111, the first accommodating cavity 11111 is a part of the heat dissipation cavity 1111. That is, the first accommodating cavity 11111 and the first vent 1112 (as shown in FIG. Figure 5A As shown) are also connected, the first vent 1112 and the heat dissipation gap 14 (as shown Figure 3A As shown in FIG. 1 ) and the first accommodating chamber 11111, heat exchange can be performed between the first accommodating chamber 11111. Figure 5C As shown, the limiting member 112 divides the heat dissipation cavity 1111 into a second accommodating cavity 11112 and a third accommodating cavity 11113 along the extension direction of the limiting member 112. Similarly, the second accommodating cavity 11112 and the third accommodating cavity 11113 are also part of the heat dissipation cavity 1111, so the first accommodating cavity 11111 and the second accommodating cavity 11112 can exchange heat with the first vent 1112 and the heat dissipation gap 14.

[0073] On this basis, if Figure 3A or Figure 3B As shown, the heat dissipation structure 11 may include at least one fan box 113, and the fan box 113 may be arranged in the heat dissipation cavity 1111 (such as Figure 5A The fan box 113 can be as shown. Figure 6 As shown, there is an air outlet 1131, and the air outlet 1131 can be oriented toward the first ventilation opening 1112 (such as Figure 5A As shown). Exemplarily, the air port 1131 of the fan box 113 may be an air inlet. When the fan box 113 is working, air is sucked into the first vent 1112 through the air port 1131, and then the gas between the first vent 1112 and the heat dissipation gap 14 flows, thereby cooling the heat dissipation gap 14. Alternatively, exemplarily, the air port 1131 of the fan box 113 may be an air outlet. When the fan box 113 is working, air is supplied to the first vent 1112 through the air port 1131, and the gas between the first vent 1112 and the heat dissipation gap 14 flows, thereby cooling the heat dissipation gap 14. To achieve the heat dissipation function.

[0074] In addition, continue as Figure 3A or Figure 3B As shown, the fan box 113 can be arranged in the first accommodating chamber 11111, the second accommodating chamber 11112 or the third accommodating chamber 11113. Alternatively, a part of the fan box 113 can be arranged in the second accommodating chamber 11112, and another part can be arranged in the third accommodating chamber 11113. Figure 3A As shown, in the early stage of the evolution of the plug-in frame 10, before the network is upgraded, the heat dissipation demand required by the plug-in frame 10 is relatively low, and the heat dissipation architecture 11 can be allowed to stop heat dissipation for a longer time. At this time, in order to reduce costs, a fan box 113 can be set in the first accommodating cavity 11111. Because the first accommodating cavity 11111 is located between the limiter 112 and the second cavity wall 1114, that is, the limiter 112 will not hinder the setting of the fan box 113 in the first accommodating cavity 11111, the size of the fan box 113 can be larger, thereby ensuring the heat dissipation demand at this time. When the fan box 113 fails or needs maintenance, the fan box 113 can also be taken out for repair or maintenance.

[0075] However, with the development of network equipment, the subracks are constantly evolving. After the network is gradually upgraded, the subracks have a large business volume and a high heat dissipation demand. The cooling architecture is allowed to stop cooling for a short time. At this time, if only one fan box is set, when the fan box is repaired or maintained, the cooling architecture stops cooling for a short time and cannot meet the cooling demand of the subrack. Figure 3B As shown, the heat dissipation structure 11 can be in the first accommodation cavity 11111 (such as Figure 5C as shown) and the second accommodating cavity 11112 (as shown Figure 5C At least two independent fan boxes 113 are provided in the frame 10. When one of the fan boxes 113 needs to be repaired or maintained, the other fan boxes 113 continue to work, ensuring that the heat dissipation architecture 11 will not completely lose its heat dissipation function to meet higher heat dissipation requirements. In addition, the frame 10 can also adjust the power consumption of different fan boxes 113 according to the heat dissipation requirements of different single-chip areas, so as to ensure the heat dissipation requirements while minimizing the overall power consumption.

[0076] In the related art, the fan box of the heat dissipation architecture is an integrated fan box, which integrates all the cooling fans together through an integrated integrated structure, and the cost is low. However, when the integrated fan box fails or needs maintenance, the integrated fan box needs to stop working. In order to ensure the normal operation of the frame, the repair or maintenance time of the integrated fan box is short, which is inconvenient to repair and cannot meet the heat dissipation requirements of the later stage of the frame evolution. Moreover, this type of frame cannot achieve partition power consumption adjustment to match the heat dissipation requirements of different areas. Alternatively, in other related technologies, the heat dissipation architecture includes a plurality of separated cavities, and a fan box is arranged in each cavity. However, this method uses multiple fan boxes, which is more expensive. Moreover, the multiple cavities are separated from each other, and the fan box with a size larger than one cavity cannot be installed in the heat dissipation architecture. And as Figure 5A As shown, the limiting member 112 of the heat dissipation structure 11 provided in the present application will not affect the fan box 113 (such as Figure 3A (as shown) creates an obstacle in the setting of the first accommodating cavity 11111, and the size of the fan box 113 can be larger. Moreover, the heat dissipation architecture 11 provided in the present application can adapt to the evolution process of the frame 10. When the business volume of the frame 10 is small and the heat dissipation demand is small, a larger fan box 113 is set to ensure the heat dissipation capacity while reducing costs. When the business volume of the frame 10 is large and the heat dissipation demand is large, multiple fan boxes 113 are set to ensure that the heat dissipation architecture 11 will not completely lose its heat dissipation function when the fan box 113 is repaired or maintained. In order to match the evolution process of the frame, the heat dissipation demand can be guaranteed before and after the network upgrade, while reducing the purpose of cost.

[0077] Or, for example, Figure 3CAs shown, the first cavity wall 1113 faces the single board 13. The first cavity wall 1113 is provided with a first vent 1112. The first vent 1112 can be surrounded by the frame of the first cavity wall 1113. The second cavity wall 1114 is provided with a second vent 1115, and the second vent 1115 is connected to the outside atmosphere. The first vent 1112 faces the heat dissipation gap 14. The fan box 113 (as shown in FIG. Figure 3A The air inlet of the fan box 113 faces the first vent 1112, and the air inlet of the fan box 113 faces the second vent 1115. When the fan box 113 is working, an airflow from the air outlet to the second vent 1115 is generated. This in turn drives the air inlet to intake air, generating an airflow from the first vent 1112 to the air inlet. This drives the gas in the heat dissipation gap 14 to flow to the first vent 1112, and finally generates an airflow that flows from the heat dissipation gap 14 to the first vent 1112, the air inlet, the air outlet, the second vent 1115 in sequence, and finally is discharged into the outside atmosphere. To complete the heat dissipation of the plug-in frame 10.

[0078] Or, if Figure 3D As shown, the second cavity wall 1114 faces the single board 13. The first vent 1112 is connected to the outside atmosphere. The second vent 1115 faces the heat dissipation gap 14. The second vent 1115 can be surrounded by the frame of the second cavity wall 1114. The fan box 113 (such as Figure 3A or Figure 3B The air inlet of the fan box 113 faces the second vent 1115, and the air inlet of the fan box 113 faces the first vent 1112. When the fan box 113 is working, an airflow from the air outlet to the first vent 1112 is generated. Then the air inlet is driven to intake air, and an airflow from the second vent 1115 to the air inlet is generated. Thereby driving the gas in the heat dissipation gap 14 to flow to the second vent 1115, and finally generating an airflow that flows from the heat dissipation gap 14 to the second vent 1115, the air inlet, the air outlet, the first vent 1112 in sequence, and finally discharged into the outside atmosphere. To complete the heat dissipation of the plug-in frame 10.

[0079] In addition, continue Figure 3C or Figure 3D As shown, the fan box 113 (such as Figure 3A or Figure 3B When the fan box 113 is installed into the heat dissipation cavity 1111 along the extension direction of the stopper 112, the fan box 113 moves toward the connector 16 until one end of the connector 16 is inserted into the connection end of the fan box 113 and is electrically connected to the fan box 113. This ensures that the fan box 113 is powered.

[0080] Exemplarily, at least one fan (not shown in the figure) is arranged in the fan box 113, and the fan is electrically connected to the connector 16. By supplying power to the fan, the fan works to dissipate heat.

[0081] The following embodiments are first described by taking the case where at least two fan boxes are arranged in the heat dissipation cavity as an example.

[0082] In some embodiments of the present application, Figure 7 As shown, the at least one stopper 112 may include a first stopper a1. The first stopper a1 divides the heat dissipation cavity 1111 into a second accommodation cavity 11112 and a third accommodation cavity 11113 along the extension direction of the first stopper a1. Figure 8 As shown, the at least one fan box 113 (such as Figure 3B As shown) may include a first fan box b1 and a second fan box b2. A first gap 114 is provided between the first fan box b1 and the second fan box b2. The first gap 114 can accommodate the first limiting member a1 to ensure that the first limiting member a1 is located between the first fan box b1 and the second fan box b2. The first fan box b1 is disposed in the second accommodating cavity 11112, and a side surface of the first fan box b1 facing the third accommodating cavity 11113 is slidably matched with the first limiting member a1. At this time, in the direction of the first fan box b1 toward the third accommodating cavity 11113, the first limiting member a1 can limit the first fan box b1 to ensure that the first fan box b1 slides along the first limiting member a1, thereby ensuring that the first fan box b1 is installed in the expected position, and then connected with the corresponding connector 16 (such as Figure 3C In addition, the second fan box b2 is arranged in the third accommodating cavity 11113, and the side surface of the second fan box b2 facing the second accommodating cavity 11112 is slidably matched with the first limiter a1. At this time, in the direction of the second fan box b2 toward the second accommodating cavity 11112, the first limiter a1 can also limit the second fan box b2, ensuring that the second fan box b2 also slides along the first limiter a1, thereby ensuring that the second fan box b2 is installed in the expected position, and then aligned with the corresponding connector 16 and electrically connected.

[0083] In other embodiments of the present application, Fig. 9 As shown, the at least one stopper 112 (such as Figure 5A The second stopper a2 is located in the third accommodating cavity 11113, and the second stopper a2 divides the third accommodating cavity 11113 into a fourth accommodating cavity 111131 and a fifth accommodating cavity 111132 along the extension direction of the second stopper a2. Fig.10As shown, the second fan box b2 is located in the fourth accommodating cavity 111131, and the side surface of the second fan box b2 facing the fifth accommodating cavity 111132 is slidably matched with the second limiter a2. At this time, the second fan box b2 is arranged behind the fourth accommodating cavity 111131, and the second limiter a2 can also limit and guide the second fan box b2. The first limiter a1 and the second limiter a2 respectively limit and guide the two sides of the second fan box b2, further ensuring that the second fan box b2 can be installed with the corresponding connector 16 (such as Figure 3C In addition, at least one fan box 113 (as shown) is aligned and electrically connected. Figure 3B As shown) also includes a third fan box b3. The number of fan boxes 113 is further increased. When one of the fan boxes 113 is repaired or maintained, the number of the remaining fan boxes 113 that are still working is relatively large, thereby ensuring that when one fan box 113 is repaired or maintained, the heat dissipation work of the other fan boxes 113 can meet the needs of the frame 10. There is a second gap 115 between the second fan box b2 and the third fan box b3. The second gap 115 can accommodate the second limiter a2 to ensure that the second limiter a2 is located between the second fan box b2 and the third fan box b3. The third fan box b3 is located in the fifth accommodating cavity 111132, and the side surface of the third fan box b3 facing the fourth accommodating cavity 111131 slides with the second limiter a2. At this time, the second limiter a2 can limit and guide the third fan box b3, ensuring that the third fan box b3 slides along the second limiter a2, thereby ensuring that the third fan box b3 can be aligned with the corresponding connector 16 and electrically connected.

[0084] In some further embodiments of the present application, Figure 5C As shown, the at least one stopper 112 may further include a third stopper a3. The third stopper a3 is located in the fifth accommodating cavity 111132, and the third stopper a3 divides the fifth accommodating cavity 111132 into a sixth accommodating cavity 111321 and a seventh accommodating cavity 111322 along the extension direction of the third stopper a3. Fig.11 As shown, the third fan box b3 is located in the sixth accommodating cavity 111321, and the side surface of the third fan box b3 facing the sixth accommodating cavity 111321 is slidably matched with the third stopper a3. The third fan box b3 is further limited by the third stopper a3, further ensuring that the third fan box b3 can be connected to the corresponding connector 16 (such as Figure 3CAs shown) are aligned and electrically connected. In addition, the at least one fan box 113 mentioned above also includes a fourth fan box b4. The total number of fan boxes 113 is further increased to ensure the heat dissipation effect of the heat dissipation architecture 11. The fourth fan box b4 is located in the seventh accommodating cavity 111322, and the side surface of the fourth fan box b4 facing the sixth accommodating cavity 111321 is slidably matched with the third limiter a3. At this time, the third limiter a3 can limit and guide the fourth fan box b4, ensuring that the fourth fan box b4 slides along the third limiter a3, thereby ensuring that the fourth fan box b4 can be aligned with the corresponding connector 16 and electrically connected.

[0085] certainly, Figure 8 , Fig.10 and Fig.11 The embodiments shown are illustrative examples in which the number of limit members is 1, 2, and 3, and the number of fan boxes is 2, 3, and 4. In other embodiments of the present application, the number of limit members and fan boxes may be other numbers. For example, the number of limit members may be 4, 5, 6, etc., and the number of fan boxes may be 5, 6, 7, etc.

[0086] In some embodiments of the present application, Figure 7 On the basis that the first limiting member a1 shown divides the heat dissipation cavity 1111 into the second accommodating cavity 11112 and the third accommodating cavity 11113, as shown in FIG. Fig.12 As shown, the at least one fan box 113 may include a first fan box b1 and a second fan box b2. The second fan box b2 is disposed in the third accommodating cavity 11113. A side surface of the second fan box b2 facing the second accommodating cavity 11112 is slidably matched with the stopper 112. The first stopper a1 can limit and guide the second fan box b2, ensuring that the first fan box b1 can be connected to the corresponding connector 16 (such as Figure 3CThe first fan box b1 is arranged in the second accommodating cavity 11112. A first slide groove b11 is provided on the side of the first fan box b1 facing the first cavity wall 1113. The first limiter a1 is located in the first slide groove b11 and cooperates with the first slide groove b11. At this time, the first limiter a1 can still limit and guide the first fan box b1, ensuring that the first fan box b1 slides along the first limiter a1, thereby ensuring that the first fan box b1 can be aligned with the corresponding connector 16 and electrically connected. In addition, the first slide groove b11 can accommodate the first limiter a1, so that there is no need to leave a gap between the first fan box b1 and the second fan box b2 that is sufficient to accommodate the first limiter a1. In other words, the gap between the surface of the first fan box b1 facing the second fan box b2 and the surface of the second fan box b2 facing the first fan box b1 can be smaller or even non-existent. As a result, the space occupied by the first fan box b1 and the second fan box b2 in the heat dissipation cavity 1111 is larger, thereby improving the space utilization rate in the heat dissipation cavity 1111.

[0087] Further, continue as Fig.12 As shown, the surface of the first fan box b1 facing the second fan box b2 abuts against the surface of the second fan box b2 facing the first fan box b1. At this time, there is no other gap between the first fan box b1 and the second fan box b2 except for the first slide groove b11 for accommodating the first stopper a1, which further increases the space occupied by the first fan box b1 and the second fan box b2 in the heat dissipation cavity 1111, thereby further improving the space utilization rate in the heat dissipation cavity 1111.

[0088] In other embodiments of the present application, Fig. 9 As shown in the figure, the second limiting member a2 divides the third accommodating chamber 11113 into a fourth accommodating chamber 111131 and a fifth accommodating chamber 111132. Fig.13 As shown, the at least one fan box 113 mentioned above may also include a third fan box b3. In this case, the number of fan boxes is greater, thereby ensuring that when one fan box is repaired or maintained, the heat dissipation of other fan boxes can meet the requirements of the plug-in frame. The second fan box b2 is arranged in the fourth accommodating cavity 111131, and the third fan box b3 is located in the fifth accommodating cavity 111132. A sixth slide groove b22 is provided on the side of the second fan box b2 facing the first cavity wall 1113. The second limit member a2 is located in the sixth slide groove b22 and cooperates with the sixth slide groove b22. To ensure that the second fan box b2 can be connected to the corresponding connector 16 (such as Figure 3CAs shown in the figure, the third fan box b3 is aligned and electrically connected with the corresponding connector 16. At the same time, as in the above embodiment, the space utilization rate in the heat dissipation cavity 1111 can be improved. The third fan box b3 is located in the fifth accommodating cavity 111132, and the side surface of the third fan box b3 facing the fourth accommodating cavity 111131 is slidably matched with the second stopper a2. This ensures that the third fan box b3 can be aligned and electrically connected with the corresponding connector 16.

[0089] certainly, Fig.12 and Fig.13 The embodiments shown are illustrative examples in which the number of limit members is 1 or 2, and the number of fan boxes is 2 or 3. In other embodiments of the present application, the number of limit members and fan boxes may be other numbers. For example, the number of limit members may be 3, 4, 5, 6, etc., and the number of fan boxes may be 4, 5, 6, 7, etc.

[0090] In some embodiments of the present application, Figure 7 The first stopper a1 shown divides the heat dissipation cavity 1111 into a second accommodating cavity 11112 and a third accommodating cavity 11113. Fig.14 As shown, the first fan box b1 is arranged in the second accommodating cavity 11112, and a first recessed portion b12 is provided on the side of the first fan box b1 facing the first cavity wall 1113. The second fan box b2 is arranged in the third accommodating cavity 11113, and a second recessed portion b21 is provided on the side of the second fan box b2 facing the first cavity wall 1113. The first recessed portion b12 and the second recessed portion b21 together form a second slide groove 116. The first limit member a1 is located in the second slide groove 116 and cooperates with the second slide groove 116. The first limit member a1 cooperates with the second slide groove 116, thereby limiting and guiding the sliding of the first fan box b1 and the second fan box b2, so as to ensure that the first fan box b1 and the second fan box b2 can both be connected to the corresponding connector 16 (such as Figure 3C At the same time, Fig.10 The second slide groove 116 can accommodate the first stopper a1, and the gap between the surface of the first fan box b1 facing the second fan box b2 and the surface of the second fan box b2 facing the first fan box b1 can be small or even non-existent, thereby improving the space utilization rate in the heat dissipation cavity 1111.

[0091] In other embodiments of the present application, Fig. 9 As shown, the second stopper a2 divides the third accommodation cavity 11113 into a fourth accommodation cavity 111131 and a fifth accommodation cavity 111132. Fig.15As shown, the at least one fan box 113 mentioned above may also include a second fan box b2 and a third fan box b3. In this case, the number of fan boxes 113 is greater, thereby ensuring that when one fan box 113 is repaired or maintained, the heat dissipation work of other fan boxes 113 can meet the needs of the frame 10. The second fan box b2 is arranged in the fourth accommodating cavity 111131, and a third recessed portion b23 is provided on the side of the second fan box b2 facing the first cavity wall 1113. The third fan box b3 is located in the fifth accommodating cavity 111132, and a fourth recessed portion b31 is provided on the side of the third fan box b3 facing the first cavity wall 1113. The third recessed portion b23 and the fourth recessed portion b31 together form the seventh slide groove 117. The second limit member a2 is located in the seventh slide groove 117 and cooperates with the seventh slide groove 117. At this time, as described above Fig.14 Similar to the embodiment shown in FIG. 1 , the second stopper a2 cooperates with the seventh slide groove 117 to limit and guide the sliding of the second fan box b2 and the third fan box b3, so as to ensure that the second fan box b2 and the third fan box b3 can be connected with the corresponding connector 16 (such as Figure 3C as shown) and electrically connect.

[0092] certainly, Fig.14 and Fig.15 The embodiments shown are illustrative examples in which the number of limit members is 1 or 2, and the number of fan boxes is 2 or 3. In other embodiments of the present application, the number of limit members and fan boxes may be other numbers. For example, the number of limit members may be 3, 4, 5, 6, etc., and the number of fan boxes may be 4, 5, 6, 7, etc.

[0093] In some embodiments of the present application, Fig. 9 As shown, the first stopper a1 divides the heat dissipation cavity 1111 into a second accommodating cavity 11112 and a third accommodating cavity 11113, and the second stopper a2 divides the third accommodating cavity 11113 into a fourth accommodating cavity 111131 and a fifth accommodating cavity 111132. Fig.16As shown, the at least one fan box 113 may include a first fan box b1 and a second fan box b2. The first fan box b1 is disposed in the second accommodating chamber 11112 and the fourth accommodating chamber 111131, and is located between the first stopper a1 and the second cavity wall 1114. The first fan box b1 and the first stopper a1 slide in cooperation with the surface of the second cavity wall 1114. At this time, the first fan box b1 can slide on the surface of the first stopper a1 toward the second cavity wall 1114, thereby realizing the installation and removal of the first fan box b1. In addition, the second fan box b2 is disposed in the fourth accommodating chamber 111131 and the fifth accommodating chamber 111132, and is located between the second stopper a2 and the second cavity wall 1114. The second fan box b2 and the second stopper a2 slide in cooperation with the surface of the second cavity wall 1114. At this time, the second fan box b2 can slide on the second stopper a2 toward the surface of the second cavity wall 1114 , thereby realizing installation and removal of the second fan box b2 , thereby realizing installation of two fan boxes 113 in the heat dissipation cavity 1111 .

[0094] Continue as Fig.16 As shown, a third slide groove b13 is provided on the side of the first fan box b1 facing the first cavity wall 1113. The first limiting member a1 is located in the third slide groove b13 and cooperates with the third slide groove b13. At this time, in a direction perpendicular to the extension direction of the first limiting member a1 and parallel to the first cavity wall 1113, the first limiting member a1 can limit the first fan box b1, so that the first limiting member a1 can guide the sliding of the first fan box b1. In addition, a fourth slide groove b24 is provided on the side of the second fan box b2 facing the first cavity wall 1113. The second limiting member a2 is located in the fourth slide groove b24 and cooperates with the fourth slide groove b24. At this time, the second limiting member a2 can also limit the second fan box b2, so that the second limiting member a2 can guide the sliding of the second fan box b2. To ensure that the first fan box b1 and the second fan box b2 can both be connected to the corresponding connector 16 (such as Figure 3C as shown) and electrically connect.

[0095] In some embodiments of the present application, Figure 5C The third stopper a3 shown divides the fifth accommodation cavity 111132 into a sixth accommodation cavity 111321 and a seventh accommodation cavity 111322. Fig.17 As shown, the at least one fan box 113 may further include a third fan box b3. The third fan box b3 is disposed in the sixth accommodating chamber 111321 and the seventh accommodating chamber 111322. An eighth slide groove b32 is disposed on the side of the third fan box b3 facing the first cavity wall 1113, and the third stopper a3 is located in the eighth slide groove b32. Fig.16The third limiter a3 can also limit the third fan box b3, so that the third limiter a3 can guide the sliding of the third fan box b3. Figure 3C as shown) and electrically connect.

[0096] certainly, Fig.16 and Fig.17 The embodiments shown are illustrative examples in which the number of limit members is 2 and 3, and the number of fan boxes is 2 and 3. In other embodiments of the present application, the number of limit members and fan boxes may be other numbers, for example, the number of limit members may be 4, 5, 6, 7, etc., and the number of fan boxes may be 4, 5, 6, 7, etc.

[0097] The following embodiments are described by taking an example of disposing a fan box in the heat dissipation cavity.

[0098] In some embodiments of the present application, Fig.18 As shown, the fan box 113 can be arranged in the first accommodating cavity 11111 (such as Figure 5B In the early stage of the frame evolution and before the network upgrade, the business volume of the frame is small, and the heat dissipation cavity 1111 (as shown) can be Figure 5A Only one fan box 113 is installed in the network (as shown), which reduces costs while meeting the low heat dissipation requirements before network upgrade.

[0099] In other embodiments of the present application, Fig.19 As shown, the fan box 113 may include a first portion 1132 and a second portion 1133. The first portion 1132 is disposed in the first accommodating cavity 11111 (eg, Figure 5B The side of the second part 1133 facing the first cavity wall 1113 is provided with a fifth slide groove 11331, and the stopper 112 is located in the fifth slide groove 11331 and cooperates with the fifth slide groove 11331. At this time, the second part 1133 of the fan box 113 is located between the side surface of the stopper 112 facing away from the first cavity wall 1113 and the first cavity wall 1113. Compared with setting the entire fan box 113 in the first accommodating cavity 11111, at this time, the fan box 113 is located in the heat dissipation cavity 1111 (as shown). Figure 5A The space in the heat dissipation cavity 1111 accounts for a large proportion, thereby improving the space utilization rate in the heat dissipation cavity 1111.

[0100] In some further embodiments of the present application, Fig. 20 As shown, the fan box 113 may include a first fan assembly 1134 and a second fan assembly 1135, and the first fan assembly 1134 and the second fan assembly 1135 are away from the heat dissipation cavity 1111 (such as Figure 5AA third gap 1136 is provided between the first fan assembly 1134 and the second fan assembly 1135. The stopper 112 (as shown) Figure 5A The first fan assembly 1134 and the second fan assembly 1135 are located in the third gap 1136. At this time, the stopper 112 is located in the third gap 1136 between the first fan assembly 1134 and the second fan assembly 1135, and the stopper 112 does not prevent the first fan assembly 1134 and the second fan assembly 1135 from being installed in the heat dissipation cavity 1111. This ensures that the fan box 113 can be installed in the heat dissipation cavity 1111 in the early stage of the frame evolution.

[0101] Alternatively, in some embodiments of the present application, the heat dissipation architecture 1111 may also be as follows: Fig.21 The figure includes a heat dissipation frame 111 and at least one stopper 112. The heat dissipation frame 111 has a heat dissipation cavity 1111. The heat dissipation frame 111 includes a first cavity wall 1113 and a second cavity wall 1114 that are arranged opposite to each other. The stopper 112 is located in the heat dissipation cavity 1111, and the first end 1121 of the stopper 112 is detachably connected to the first cavity wall 1113. In the early stage of the evolution of the plug-in frame, before the network is upgraded, the heat dissipation demand is relatively low. At this time, after the stopper 112 is detached from the first cavity wall 1113, a larger fan box 113 can be installed in the heat dissipation cavity 1111. As the subrack 10 evolves, after the network is upgraded, when the heat dissipation requirement is high, after the stopper 112 is installed on the first cavity wall 1113, the stopper 112 can divide the heat dissipation cavity 1111 into at least two independent cavities, and at least two independent fan boxes 113 can be set respectively, so as to ensure that when the fan boxes 113 are repaired or maintained, they can be repaired one by one, and at least one fan box 113 is in working state to meet the heat dissipation requirement. In this way, the heat dissipation requirement can be guaranteed before and after the network upgrade, and the cost can be reduced at the same time.

[0102] For example, continue as Fig.21 As shown, the second end 1122 of the stopper 112 may abut against the second cavity wall 1114. Alternatively, there may be a gap between the second end 1122 of the stopper 112 and the second cavity wall 1114. Alternatively, the second end 1122 of the stopper 112 and the second cavity wall 1114 may be detachably connected to ensure that the stopper 112 can be detached from the heat dissipation frame 111.

[0103] In other embodiments of the present application, Fig.21 As shown, the first end 1121 of the stopper 112 is fixedly connected to the first cavity wall 1113, and the second end 1122 of the stopper 112 is connected to the second cavity wall 1114. At this time, the stopper 112 is fixed more firmly, ensuring the connection stability between the stopper 112 and the heat dissipation frame 111. On this basis, Fig. 20As shown, the fan box 113 may include a first fan assembly 1134 and a second fan assembly 1135, and the first fan assembly 1134 and the second fan assembly 1135 are connected on a side away from the heat dissipation cavity 1111. A third gap 1136 is provided between the first fan assembly 1134 and the second fan assembly 1135. The stopper 112 is located in the third gap 1136, and the stopper 112 does not hinder the first fan assembly 1134 and the second fan assembly 1135 from being installed in the heat dissipation cavity 1111. In this way, it can be ensured that in the early stage of the evolution of the frame 10, the fan box 113 can be installed in the heat dissipation cavity 1111 to meet the low heat dissipation requirements before the network upgrade. After the network upgrade, two independent fan boxes 113 can be replaced and installed in the second accommodating cavity 11112 and the third accommodating cavity 11113 respectively, so as to ensure that when the fan box 113 is repaired or maintained, it can be carried out one by one, and at least one fan box 113 is in working state to meet the heat dissipation requirements. This is to ensure heat dissipation requirements before and after network upgrades while reducing costs.

Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
