Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and in particular to switch chassis. Background Technology

[0002] A switch chassis is a network device used for forwarding optical (electrical) signals. The chassis itself integrates numerous high-power, high-density operating modules, such as service modules, power modules, control modules, and expansion modules. These modules generate a significant amount of heat during operation; if not dissipated in time, their operating temperatures will rise continuously, affecting their reliability.

[0003] In related technologies, switch chassis are equipped with air-cooled heat dissipation modules to cool the operating modules. In conventional designs, the chassis body has a longitudinal length and a transverse width. The air-cooled heat dissipation module typically extends laterally and is arranged laterally alongside some operating modules, with the air inlet and outlet of the air-cooled heat dissipation module positioned opposite each other longitudinally. This arrangement causes the air-cooled heat dissipation module to occupy a large amount of transverse space, compressing the layout space of the operating modules and affecting the scalability and flexibility of the overall switch chassis configuration. Summary of the Invention

[0004] Therefore, it is necessary to provide a switch chassis to address the problem that extending the air-cooled heat dissipation module horizontally and distributing it side-by-side with some operating modules horizontally encroaches on the layout space of the operating modules and affects the scalability and flexibility of the overall configuration of the switch chassis.

[0005] A switch chassis, comprising:

[0006] The chassis body has a first space and a second space that are connected in a longitudinal direction. The chassis body is also provided with an airflow inlet and an airflow outlet. The airflow inlet is connected to the first space and the airflow outlet is connected to the second space.

[0007] The operation module includes a first operation sub-module and a second operation sub-module. The first operation sub-module is located in a first space, and the second operation sub-module is located in a second space.

[0008] A wind-cooled heat dissipation module is disposed in the second space and extends longitudinally. The wind-cooled heat dissipation module and the second working sub-module located at least partially in the second space are arranged side by side in the transverse direction, with the transverse and longitudinal directions forming an angle. The wind-cooled heat dissipation module is used to drive airflow to flow in from the airflow inlet, flow through the first space and the second space in sequence, and discharge from the airflow outlet to cool the working module.

[0009] In one embodiment, the second operating sub-modules arranged side by side with the air-cooled heat dissipation module are all located on the same side of the air-cooled heat dissipation module. The air-cooled heat dissipation module is provided with an air intake and an air exhaust. The air intake faces the second operating sub-modules arranged side by side with the air-cooled heat dissipation module, and the air exhaust is connected to the airflow outlet.

[0010] In one embodiment, the switch chassis further includes:

[0011] An air duct is formed inside the chassis body. The two ends of the air duct are connected to the first space and the second space respectively along the longitudinal direction. The width of the air duct gradually decreases towards the second space.

[0012] In one embodiment, the air-cooled heat dissipation module is located on the side of the air outlet path formed by the end of the air guide channel communicating with the second space, and the air intake of the air-cooled heat dissipation module faces the air outlet path.

[0013] In one embodiment, the interior of the chassis body is provided with a first air guide plate and a second air guide plate that are laterally opposite and spaced apart, and an air guide channel is formed between the first air guide plate and the second air guide plate.

[0014] In one embodiment, the first air guide plate is provided with multiple through holes, and the projection of a portion of the second operation sub-module located in the second space onto the reference plane is located within the projection of the first air guide plate onto the reference plane, which is a plane perpendicular to the longitudinal direction.

[0015] In one embodiment, the chassis body is provided with a disassembly port, which communicates with the second space. The air-cooled heat dissipation module is detachably connected to the chassis body and can be disassembled from the chassis body through the disassembly port.

[0016] In one embodiment, the air-cooled heat dissipation module includes multiple air-cooled heat dissipation components distributed longitudinally at intervals. Each air-cooled heat dissipation component is provided with a snap-fit ​​mechanism between itself and the chassis body, and each air-cooled heat dissipation component is snapped into the chassis body through a corresponding snap-fit ​​mechanism.

[0017] In one embodiment, the airflow inlet, the first space, the second space and the airflow outlet are connected in sequence to form a heat dissipation channel, and the interior of the chassis body has multiple heat dissipation channels that are independent of each other in the lateral direction.

[0018] The air-cooled heat dissipation modules located in the second space of each heat dissipation channel extend longitudinally and are arranged side by side with at least a portion of the second working sub-modules in the corresponding second space in the transverse direction.

[0019] In one embodiment, the first operation sub-module includes a service module; and / or,

[0020] The second operating sub-module includes at least one of an expansion module, a management and control module, and a power supply module.

[0021] In the aforementioned switch chassis, the air-cooled heat dissipation module extends longitudinally, and the air-cooled heat dissipation module and at least some of the second operating sub-modules are arranged side-by-side laterally within the second space. Compared to traditional solutions where the air-cooled heat dissipation module extends laterally and is arranged side-by-side with some operating modules, resulting in the air-cooled heat dissipation module compressing the available installation width of the operating modules and making it difficult to install more operating modules, this solution, with the same lateral dimensions of the second space, frees up more lateral installation space by arranging the air-cooled heat dissipation module longitudinally. This allows more second operating sub-modules to be accommodated side-by-side laterally within the second space, improving the scalability and flexibility of the overall switch chassis configuration.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0045] See Figure 1A switch chassis includes a chassis body 10, an operating module 20, and an air-cooled heat dissipation module 30. The chassis body 10 has a first space 102 and a second space 103 connected longitudinally inside. The chassis body 10 is also provided with an airflow inlet 101 and an airflow outlet 104. The airflow inlet 101 is connected to the first space 102, and the airflow outlet 104 is connected to the second space 103. The operation module 20 includes a first operation sub-module and a second operation sub-module. The first operation sub-module is located in the first space 102, and the second operation sub-module is located in the second space 103. The air-cooled heat dissipation module 30 is located in the second space 103 and extends longitudinally. The air-cooled heat dissipation module 30 and the second operation sub-module located at least partially in the second space 103 are arranged side by side in the transverse direction, with the transverse direction and the longitudinal direction forming an angle. The air-cooled heat dissipation module 30 is used to drive the external airflow to flow in from the airflow inlet 101, flow through the first space 102 and the second space 103 in sequence, and be discharged from the airflow outlet 104 to cool the operation module 20. Figure 1 In the diagram, the Y direction is the vertical direction, and the X direction is the horizontal direction.

[0046] In the aforementioned switch chassis, the air-cooled heat dissipation module 30 extends longitudinally, and the air-cooled heat dissipation module 30 and at least some of the second operating sub-modules are arranged side-by-side laterally within the second space 103. Compared to the conventional technical solution where the air-cooled heat dissipation module 30 extends laterally and is arranged side-by-side with some operating modules 20, resulting in the air-cooled heat dissipation module 30 compressing the available installation width of the operating modules 20 and making it difficult to install more operating modules 20, this solution, with the same lateral dimension of the second space 103, uses a longitudinally extending air-cooled heat dissipation module 30 layout, which frees up more lateral installation space, allowing more second operating sub-modules to be arranged side-by-side laterally within the second space 103, thus improving the scalability and flexibility of the overall switch chassis configuration.

[0047] It is understandable that the longitudinal extension of the air-cooled heat dissipation module 30 means that the longitudinal length of the air-cooled heat dissipation module 30 is greater than its transverse width.

[0048] See Figure 1 and Figure 2In some embodiments, the second operating sub-modules arranged horizontally alongside the air-cooled heat dissipation module 30 are all located on the same side of the air-cooled heat dissipation module 30. The air-cooled heat dissipation module 30 is provided with an air intake 301 and an air exhaust 302. The air intake 301 faces the second operating sub-modules arranged alongside the air-cooled heat dissipation module 30, and the air exhaust 302 is connected to the airflow outlet 104. When the air-cooled heat dissipation module 30 is working, the airflow outside the chassis body 10 enters the first space 102 through the airflow inlet 101, flows through the first space 102 and the second space 103 in sequence, and is finally discharged from the airflow outlet 104, thereby performing air cooling for the operating modules 20 in the first space 102 and the second space 103.

[0049] By orienting the air intake 301 of the air-cooled heat dissipation module 30 toward the second working sub-module in the second space 103, and avoiding the second working sub-module in the second space 103 being located on the side away from the air intake 301, the airflow drawn by the air-cooled heat dissipation module 30 is made to flow through the second working sub-module as much as possible, thereby improving the heat dissipation efficiency.

[0050] See Figures 1 to 3 In some embodiments, an air guide channel 105 is also formed inside the chassis body 10. Longitudinally, the two ends of the air guide channel 105 connect to the first space 102 and the second space 103, respectively. The width of the air guide channel 105 gradually decreases towards the second space 103. This arrangement ensures that as airflow passes through the air guide channel 105 into the second space 103 from the first space 102, the lateral width of the air guide channel 105 gradually decreases. This causes the air guide channel 105 to accelerate the airflow, increasing its velocity and thus enhancing the heat dissipation effect on the second operating sub-module within the second space 103.

[0051] In some embodiments, the air-cooled heat dissipation module 30 is located to the side of the air outlet path formed by the end of the air guide channel 105 communicating with the second space 103, and the air intake 301 of the air-cooled heat dissipation module 30 faces the air outlet path. In the second operating sub-modules within the second space 103, some second operating sub-modules face the end of the air guide channel 105 communicating with the second space 103, that is, they are located on the air outlet path of the air guide channel 105; other second operating sub-modules are located to the side of the air outlet path of the air guide channel 105, and are arranged laterally and relatively spaced on both sides of the air outlet path from the air-cooled heat dissipation module 30. This arrangement avoids the air-cooled heat dissipation module 30 directly facing the air guide channel 105, thus preventing the airflow drawn from the air guide channel 105 from being directly drawn away by the air-cooled heat dissipation module 30. At the same time, placing some of the second operating sub-modules on the air outlet path of the air guide channel 105 allows for priority and efficient heat dissipation of these second operating sub-modules. Placing the other part of the second operating sub-modules on the side of the air outlet path of the air guide channel 105 away from the air-cooled heat dissipation module 30 allows for auxiliary heat dissipation of these second operating sub-modules by utilizing the lateral suction airflow generated by the air-cooled heat dissipation module 30, thereby optimizing the heat dissipation effect on the second space 103.

[0052] In some embodiments, the heat output of the second operating sub-module located on the air outlet path of the air guide channel 105 is higher than that of the second operating sub-module located on the side of the air outlet path of the air guide channel 105. This arrangement allows the second operating sub-module located on the air outlet path of the air guide channel 105 to receive more concentrated airflow cooling, thus optimizing the heat dissipation effect.

[0053] See Figure 1 In some embodiments, the first operation sub-module includes a service module 21, that is, the service module 21 is disposed within the first space 102. The overall size of the service module 21 is relatively large. Placing the service module 21 within the first space 102 eliminates the need for other first operation sub-modules to occupy the first space 102, thus facilitating the arrangement of the service module 21.

[0054] In some embodiments, a plurality of service modules 21 are disposed within the first space 102, and the plurality of service modules 21 are distributed longitudinally, with adjacent service modules 21 being staggered laterally. This arrangement can reduce the facing area of ​​two adjacent service modules 21 and improve the heat dissipation efficiency of each service module 21.

[0055] In some embodiments, the second operating sub-modules located within the second space 103 are arranged longitudinally. Each second operating sub-module within the second space 103 includes a management and control module 22 and a power supply module 23. The management and control module 22 is located on the air outlet path of the air guide channel 105, and the power supply module 23 is located to the side of the air outlet path of the air guide channel 105, and is arranged laterally at a distance from the air-cooled heat dissipation module 30. The heat dissipation power of the management and control module 22 is higher than that of the power supply module 23. This arrangement allows the management and control module 22 to preferentially receive the airflow flowing out of the air guide channel 105 and the lateral suction airflow generated by the air-cooled heat dissipation module 30, thereby improving the heat dissipation efficiency of the management and control module 22.

[0056] It is understandable that the second operation sub-modules located in the second space 103 are arranged to extend longitudinally, which means that the longitudinal length of each second operation sub-module is greater than its transverse width.

[0057] In some embodiments, the second operation sub-module located in the second space 103 further includes an expansion module located between the management and control module 22 and the power module 23.

[0058] In some embodiments, the interior of the chassis body 10 is provided with a first air guide plate 151 and a second air guide plate 152 that are laterally opposite and spaced apart, forming an air guide channel 105 between the first air guide plate 151 and the second air guide plate 152. This arrangement facilitates the formation of the air guide channel 105, and the structure of the first air guide plate 151 and the second air guide plate 152 is simple, making it easy to process and install.

[0059] See Figures 1 to 3 In some embodiments, the first air guide plate 151 is provided with a plurality of guide holes 1511. The projection of a portion of the second operating sub-modules located in the second space 103 onto a reference plane lies within the projection of the first air guide plate 151 onto the reference plane, which is a plane perpendicular to the longitudinal direction. The portion of the second operating sub-modules located in the second space 103 is arranged longitudinally opposite to the first air guide plate 151, and the heat generation power of this portion of the second operating sub-modules is less than the heat generation power of the second operating sub-modules located on the air outlet path of the air guide channel 105. The plurality of guide holes 1511 on the first air guide plate 151 allow the airflow in the first space 102 to enter the second space 103 through the guide holes 1511 and flow through the second operating sub-modules arranged longitudinally opposite to the first air guide plate 151, thereby enhancing the heat exchange effect on this portion of the second operating sub-modules.

[0060] In some embodiments, the power supply module 23 is arranged longitudinally opposite to the first air guide plate 151, the air-cooled heat dissipation module 30 is arranged longitudinally opposite to the second air guide plate 152, and the management and control module 22 is located on the air outlet path of the air guide channel 105.

[0061] See Figures 1 to 4 In some embodiments, the chassis body 10 is provided with a disassembly port 106, which communicates with the second space 103. The air-cooled heat dissipation module 30 is detachably connected to the chassis body 10 and can be installed and removed from the chassis body 10 through the disassembly port 106. This configuration allows the air-cooled heat dissipation module 30 to be installed and removed without disassembling the entire chassis body 10, improving the ease of maintenance for the air-cooled heat dissipation module 30.

[0062] In some embodiments, the air-cooled heat dissipation module 30 includes multiple air-cooled heat dissipation components 31 spaced longitudinally. Each air-cooled heat dissipation component 31 is provided with a snap-fit ​​mechanism 40 between itself and the chassis body 10, and each air-cooled heat dissipation component 31 is snapped into the chassis body 10 through a corresponding snap-fit ​​mechanism 40. This snap-fit ​​design improves the ease of individual replacement of each air-cooled heat dissipation component 31. Furthermore, the multiple air-cooled heat dissipation components 31 allow for adjustment of their operating status based on the heat generation of the working module 20 within the chassis body 10, preventing energy waste.

[0063] See Figure 3 , Figure 5 and Figure 6 In some embodiments, the snap-fit ​​mechanism 40 includes a snap-fit ​​portion 41 and a mating portion 42. The snap-fit ​​portion 41 is disposed on the chassis body 10 and has a snap-fit ​​groove 411. The mating portion 42 is disposed on the air-cooled heat sink 31 and is configured to deform under external force and at least partially embed into and snap into the snap-fit ​​groove 411. This configuration facilitates quick assembly and disassembly between the air-cooled heat sink 31 and the chassis body 10.

[0064] In some embodiments, two locking mechanisms 40 are provided between each air-cooled heat sink 31 and the chassis body 10. The locking portions 41 of the two locking mechanisms 40 corresponding to each air-cooled heat sink 31 are arranged longitudinally opposite each other on both sides of the air-cooled heat sink 31. The locking portions 41 are plate-shaped structures that extend laterally and are perpendicular to the longitudinal direction. Two mating portions 42 on each air-cooled heat sink 31 are arranged longitudinally opposite each other on both sides of the air-cooled heat sink 31. This arrangement can avoid interference between the locking mechanisms 40 and the air intake 301 and exhaust 302 of the air-cooled heat sink 31.

[0065] See Figures 3 to 6In some embodiments, the slot 411 is provided at one end of the latching portion 41 near the disassembly port 106. The mating portion 42 includes a connecting rib 421, an elastic arm 422, and a locking block 423. The connecting rib 421 is provided on the air-cooled heat sink 31 and is provided near the corresponding latching portion 41. One end of the elastic arm 422 is connected to the connecting rib 421, and the other end extends toward the disassembly port 106. A deformation space 3101 is formed between the elastic arm 422 and the air-cooled heat sink 31. The locking block 423 is provided at the end of the elastic arm 422 away from the connecting rib 421 and is located on the side opposite to the air-cooled heat sink 31.

[0066] When the air-cooled heat sink 31 needs to be removed through the disassembly port 106, press the elastic arms 422 on both sides of the air-cooled heat sink 31 towards the air-cooled heat sink 31. The elastic arms 422 deform towards the air-cooled heat sink 31, so that the locking block 423 disengages from the slot 411. Then, the air-cooled heat sink 31 can be taken out through the disassembly port 106. After the pressing action is released, the elastic arms 422 automatically return to their original position. When the air-cooled heat sink 31 needs to be installed, press the elastic arms 422 towards the air-cooled heat sink 31. The elastic arms 422 deform towards the air-cooled heat sink 31, and the air-cooled heat sink 31 is gradually placed between two adjacent locking parts 41 until the locking block 423 aligns with the slot 411 and slides in. After releasing, the elastic arms 422 spring back, and the locking block 423 locks into the slot 411, completing the assembly of the air-cooled heat sink 31.

[0067] See Figure 4 , Figure 6 and Figure 7 In some embodiments, each air-cooled heat sink 31 has a mounting bracket 32 ​​near the disassembly port 106. The mounting bracket 32 ​​includes a horizontal plate and two vertical plates extending away from the disassembly port 106, each vertical plate having a mating part 42. Furthermore, the circuit board 311 of each air-cooled heat sink 31 is mounted on one of the vertical plates and is arranged laterally with the mating part 42 on that vertical plate. The mounting plate 11 of the chassis body 10 also has a connector 312 that mates with the circuit board 311. The circuit board 311 and the connector 312 are inserted and mated along the insertion / removal direction of the air-cooled heat sink 31. This arrangement allows the circuit board 311 to be pulled out simultaneously when disassembling the air-cooled heat sink 31, improving disassembly and assembly efficiency.

[0068] In some embodiments, the mating portions 42 on two adjacent air-cooled heat sinks 31 share a single snap-fit ​​portion 41, meaning that the snap-fit ​​portion 41 and the air-cooled heat sink 31 are alternately distributed along the longitudinal direction. This arrangement improves the structural compactness of the device.

[0069] See Figure 3In some embodiments, the switch chassis further includes a connecting plate 17 extending longitudinally and perpendicular to the transverse direction. The latching portion 41 is a plate-like structure extending laterally and perpendicular to the longitudinal direction. One end of each latching portion 41 near the air intake 301 of the air-cooled heat sink 31 is connected to the connecting plate 17. The connecting plate 17 is disposed on one side of the air intake 301 of the multiple air-cooled heat sinks 31, and has multiple through holes 171, each through hole 171 being directly opposite the corresponding air intake 301 of the air-cooled heat sink 31. The connecting plate 17 or the latching portion 41 is detachably connected to the chassis body 10. This configuration improves the overall installation efficiency of the connecting plate 17 and the latching portion 41.

[0070] See Figures 1 to 4 In some embodiments, the chassis body 10 is generally a cubic box-shaped structure. The chassis body 10 includes a mounting plate 11 and a cover plate 14, which are arranged opposite to and parallel to each other. Both the mounting plate 11 and the cover plate 14 are rectangular plate structures extending longitudinally. The chassis body 10 also includes two side plates 12 arranged laterally opposite to both sides of the mounting plate 11 and the cover plate 14, and two end plates 13 arranged longitudinally opposite to both ends of the mounting plate 11 and the cover plate 14. The mounting plate 11, the cover plate 14, the two side plates 12, and the two end plates 13 together form the outer contour of the chassis body 10.

[0071] In some embodiments, each working module 20 is mounted on a mounting plate 11. The cover plate 14 is detachably connected to the side plate 12 or the end plate 13. A disassembly port 106 is provided on the cover plate 14. The end plate 13 corresponding to the second space 103 is provided with a clearance port for avoiding the cable or wiring port of the second working sub-module located in the second space 103. This arrangement facilitates the assembly of each working module 20 and the quick replacement and maintenance of the air-cooled heat sink 31.

[0072] In some embodiments, the air-cooled heat dissipation module 30 is disposed near the side plate 12, and the side plate 12 is provided with multiple airflow outlets 104, which are directly opposite to the exhaust vents 302 of the multiple air-cooled heat dissipation components 31. The end of each snap-fit ​​portion 41 away from the connecting plate 17 abuts against or is fixedly connected to the side plate 12. This arrangement can improve the compactness of the structural layout of the device.

[0073] In some embodiments, the end of the second air guide plate 152 away from the first space 102 is fixedly connected to the end of the connecting plate 17 near the first space 102. This arrangement allows the airflow in the first space 102 to flow more smoothly to the air intake 301 of each air-cooled heat sink 31, improving the efficiency of the air-cooled heat sink 31 in drawing airflow from the first space 102.

[0074] In some embodiments, the airflow inlet 101, the first space 102, the second space 103, and the airflow outlet 104, which are connected in sequence, form a heat dissipation channel. The interior of the chassis body 10 has multiple heat dissipation channels that are independent of each other in the lateral direction. The air-cooled heat dissipation modules 30 located in the second space 103 of each heat dissipation channel all extend longitudinally and are arranged side by side in the lateral direction with at least a portion of the second operating sub-modules in the corresponding second space 103. This arrangement allows each air-cooled heat dissipation module 30 to dissipate heat from the operating module 20 located in the corresponding heat dissipation channel. It can adjust the working state of each operating module 20 according to the working state of the operating module 20 in the corresponding heat dissipation channel, realize heat dissipation on demand, and reduce energy waste.

[0075] In some embodiments, at least one longitudinally extending partition plate 16 is provided inside the chassis body 10, dividing the interior of the chassis body 10 into multiple transversely arranged heat dissipation channels. Air-cooled heat dissipation modules 30 are symmetrically arranged in the two heat dissipation channels located at the transverse ends. When the number of heat dissipation channels is greater than three, in the remaining heat dissipation channels excluding the transverse ends, each air-cooled heat dissipation component 31 can be positioned close to the corresponding partition plate 16. The air intake 301 of each air-cooled heat dissipation component 31 has a transverse air intake direction, and the exhaust 302 can face the cover plate 14 or the mounting plate 11. The cover plate 14 or the mounting plate 11 is provided with corresponding airflow outlets 104.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
