Description

Technical Field

[0001] This application relates to the field of connection bracket technology, specifically to a mounting bracket, a cooling fan, and a network device. Background Technology

[0002] In the assembly of various industrial equipment, connecting brackets are sometimes designed to install components onto the equipment. These brackets pre-fix the components and can be tailored to the structural characteristics of the equipment to facilitate connection, thereby improving the compatibility between the components and the equipment and simplifying assembly operations. Therefore, the design of component assembly using connecting brackets has a wide range of applications.

[0003] Taking network equipment as an example, network equipment is the infrastructure that constitutes a computer network. Depending on their purpose, they can be divided into various types such as servers, switches, industrial control computers, and personal computers. The network equipment listed above typically has a chassis, inside which core components such as the CPU, power supply, hard drive, and cooling fan are installed. Sometimes, the hard drive and cooling fan need to be removed from the chassis for replacement or maintenance. To facilitate disassembly and assembly, the hard drive and cooling fan are usually first installed on matching mounting brackets, and then the mounting brackets are fixed to the chassis using a detachable connection.

[0004] In existing network equipment, brackets used to install hard drives and cooling fans are usually fixed in the chassis by screws or clips. When the chassis is subjected to external impact and vibrates, the bracket will vibrate along with the chassis, which can cause the connection between the bracket and the chassis to loosen, affecting the connection stability of the hard drive and cooling fan.

[0028] In network devices such as servers, switches, industrial PCs, and personal computers, hard drives and cooling fans are critical components for ensuring normal operation. Hard drives store data written to them, including the operating system, applications, and user files, allowing the device to access this data as needed. Cooling fans dissipate heat generated by components like the CPU, power supply, and hard drive, preventing overheating that could lead to sluggish performance or even burnout.

[0029] During the use of network equipment, hard drives and cooling fans sometimes need to be removed from the chassis. For example, hard drives may need to be transferred from one device to another to save significant data transfer time, and when a hard drive fails, it needs to be replaced. Over time, cooling fans accumulate more and more dust on their blades and air intakes, affecting their cooling performance. In such cases, the cooling fan usually needs to be removed, cleaned, and then reinstalled into the chassis. To facilitate the installation and removal of hard drives and cooling fans, they are typically mounted on matching mounting brackets. This allows for the design of compatible connection structures on the mounting brackets based on the chassis structure, enabling quick and efficient installation and removal of the hard drive or cooling fan from the chassis.

[0030] Currently, the connection between mounting brackets and chassis is generally achieved by screw locking or clip-on connection. Since these connection methods completely fix the mounting bracket to the chassis, when the chassis is subjected to external impact and vibration, the bracket will vibrate along with the chassis. The vibration amplitude is large and cannot be stopped quickly, which makes the connection between the bracket and chassis prone to loosening under the influence of vibration.

[0031] Based on this, this application provides a mounting bracket, which incorporates a shock-absorbing structure in the direction where vibration is more severe, allowing the shock-absorbing structure to abut against the side wall of the equipment. An elastically deformable clamping structure is arranged in the same direction to clamp and fix the bracket to the corresponding position on the equipment. This design allows the clamping structure to buffer vibrations through elastic deformation during vibration, maintaining stable clamping throughout the process. Simultaneously, the shock-absorbing structure dissipates the energy of the vibration, causing it to stop quickly, thus achieving a balance between connection stability and vibration resistance.

[0032] The mounting bracket provided in this application can connect the component to be installed to an external device. For example, the component to be installed can be a hard drive, a cooling fan, etc., and the external device can be a network device with a chassis, such as a server, switch, industrial control computer, or personal computer.

[0033] The external device connected to the mounting bracket has two side walls opposite each other along a first direction and a connecting part located between the two side walls. The connecting part is spaced apart from and fixed relative to the side walls, and extends in a plane perpendicular to the first direction. For example, the first direction can be vertical. The chassis of the network device has a top plate and a bottom plate opposite each other along the vertical direction. A side plate can be connected between the top plate and the bottom plate. The connecting part can be a railing, protrusion, plate-like structure, etc., fixed to the side plate, and the structure extends in a horizontal plane so that it has a certain contact area on both opposite sides along the vertical direction.

[0034] Based on the above application scenarios, please refer to Figure 1 The mounting bracket 100 includes a bracket body 11, a connecting assembly 12, and a shock-absorbing assembly 13. The bracket body 11 is installed between two side walls and can be used to fix the parts to be installed. The bracket body 11 can be set as a hollow shell or frame, and can be provided with connecting holes, connecting columns, etc., as needed. There are no specific limitations, as long as it can connect and fix the parts to be installed.

[0035] Please see Figure 2The connecting assembly 12 has two clamping members 121 arranged opposite each other along a first direction. Both clamping members 121 are slidably connected to the bracket body 11 along the first direction and are located on opposite sides of the connecting portion along the first direction, respectively. They can jointly clamp and fix the bracket body 11 to the connecting portion. With this arrangement, the bracket body 11 can be connected to an external device. Furthermore, the portion of the clamping member 121 that contacts the connecting portion is elastically deformable. This elastic deformation allows for a certain degree of relative movement between the bracket body 11 and the external device, such as vibration caused by external impact. Simultaneously, the clamping member 121 can generate an elastic force that resists this relative movement, thus providing initial cushioning.

[0036] Please continue reading. Figure 1 The damping component 13 is disposed on at least one side of the support body 11 along the first direction and abuts against the side wall of the external equipment. The damping component 13 generates damping that impedes relative motion, converting kinetic energy into heat energy. This dissipates the energy of vibration during an event, causing the vibration to stop quickly and achieving a damping effect. The damping component 13 typically includes a damper. Depending on the type of damper, the damping can take the form of frictional resistance, viscous fluid resistance, etc. This embodiment does not limit the specific form of the damping component 13, as long as it meets the usage requirements.

[0037] In one usage scenario, the external device connected to the mounting bracket 100 is a server. Considering that the server is installed in a server rack, specifically, the rack has multiple mounting positions in the vertical direction. The server is placed in the mounting position of the rack and then fixed to the rack's uprights by the mounting ears on the left and right sides of the front panel, restricting the server's movement in the front-rear direction. Furthermore, guide rails are usually provided on the left and right sides inside the rack, allowing the server to slide into the rack along the rails and limiting its lateral movement, thus effectively restricting the server's movement in the horizontal direction. However, the vertical connection structure between the server and the rack is relatively weak compared to the horizontal structure, and there are gaps between each layer of equipment in the rack. This makes the server more susceptible to significant vertical vibrations when subjected to external impacts.

[0038] Based on the above considerations, the first direction can be specified as follows: Figure 1 and Figure 2 In the vertical direction shown, the two clamping members 121 respectively abut against the upper and lower sides of the corresponding connecting part of the server chassis, forming a clamping and fixing in the vertical direction. Simultaneously, the shock-absorbing component 13 is disposed on at least one side of the bracket body 11, for example, on the top of the bracket body 11, so that the shock-absorbing component 13 abuts against the top wall of the chassis. When two shock-absorbing components 13 are provided, such as... Figure 1As shown, the two shock-absorbing components 13 can be respectively installed on the upper and lower sides of the bracket body 11, so that the two shock-absorbing components 13 abut against the top and bottom walls of the chassis.

[0039] With this configuration, when the server vibrates, the elastic deformation of the clamp 121 allows for relative vertical movement between the server chassis and the bracket body 11. The clamp 121 also generates an elastic force that resists this relative movement during deformation, thus buffering the vibration. Simultaneously, since the shock-absorbing component 13 is connected to the bracket body 11 and abuts against the top or bottom wall of the chassis, it is also affected by the vibration. The components in the shock-absorbing component 13 generate damping, dissipating the vibration energy as heat, thereby stopping the vibration. After the vibration stops, the clamp 121 remains clamped to the connection point of the chassis, ensuring that the server chassis and components such as the cooling fan and hard drive fixed to the bracket body 11 remain stably connected, effectively resisting vibration impacts and ensuring the reliability of the server.

[0040] It is understandable that when the mounting bracket 100 is applied to devices other than servers, the above-mentioned design of the mounting bracket 100 can achieve similar effects, and will not be elaborated here. Furthermore, the first direction can usually be specified as the direction in which vibration is more severe during actual use of the device, and is not limited to the vertical direction.

[0041] The mounting bracket 100 provided in this embodiment has a connecting component 12 on the bracket body 11. Two clamping members 121 arranged opposite each other in the connecting component 12 are used to clamp the external device onto the connection part, and the position of the clamping members 121 in contact with the connection part can be elastically deformed. This design ensures that the clamping members 121 are stably in contact with and clamped to the external device, and also allows relative movement between the external device and the bracket body 11 under vibration conditions. Compared with a completely fixed connection method, it has a better vibration buffering effect. At the same time, by setting the shock absorption component 13, vibration energy can be consumed when vibration occurs, causing the vibration to stop quickly, thereby effectively reducing the impact of vibration and ensuring the reliability of the components installed on the mounting bracket 100.

[0042] To facilitate the connection between the clamping member 121 and the support body 11, in some embodiments, such as Figure 1 and Figure 2As shown, the support body 11 is provided with a plurality of connecting arms 111 corresponding one-to-one with the clamping member 121. Each connecting arm 111 extends perpendicularly to the first direction to form a platform that allows the clamping member 121 to slide along the first direction. It can be understood that the connecting arms 111 corresponding to two oppositely arranged clamping members 121 are usually spaced apart from each other in the first direction to form a space between the two connecting arms 111 for the clamping member 121 to slide and adjust.

[0043] Please continue reading. Figure 2 Each clamping component 121 includes a first screw 1211 and a clamping plate 1212. Each connecting arm 111 has a threaded hole (not shown in the figure) extending along a first direction. The first screw 1211 passes through the corresponding threaded hole and engages with it, allowing it to extend and retract along the first direction during rotation. The clamping plate 1212 is fixedly connected to one end of the first screw 1211 that passes through the threaded hole, and can move synchronously with the first screw 1211. Driven by the first screw 1211, it moves along the first direction towards the connection part of the external equipment, thereby clamping and fixing it to the connection part. The clamping plate 1212 is elastically deformable to buffer vibrations between the support body 11 and the external equipment.

[0044] When using the clamping member 121 described above, the first screw 1211 can be rotated counterclockwise to move the corresponding clamping plate 1212 away from the other opposite clamping plate 1212, creating a space between the two clamping plates 1212 sufficient to accommodate the connecting part. Then, the mounting bracket 100 is brought close to the connecting part, positioning it between the two clamping plates 1212. After determining the installation position, the first screw 1211 is rotated clockwise to bring the two clamping plates 1212 closer together, abutting against both sides of the connecting part. Thus, by controlling the rotation of the first screw 1211, the mounting bracket 100 can be connected to the external device. The operation is simple, and under the constraint of the threaded fit, the connection structure is not prone to loosening along the first direction, resulting in high stability. Similarly, by reversing the above operations, the mounting bracket 100 can be removed from the external device; details will not be elaborated here.

[0045] To facilitate control of the rotation of the first screw 1211, optionally, such as Figure 2 As shown, a radially extending hand-tightening knob 1211a can be provided at the head end of the first screw 1211. With this design, the user can control the rotation of the first screw 1211 by turning the hand-tightening knob 1211a. According to the principle of levers, this operation is more labor-saving than directly grasping the head end of the first screw 1211. Furthermore, the hand-tightening knob 1211a can be operated by hand without the need for tools, thus improving the convenience of operation.

[0046] To enhance the strength of the connection structure, optionally, multiple connection components 12 may be provided, each connection component 12 having two clamping members 121 opposite each other along the first direction. For example, in Figure 2 In the design shown, two connecting components 12 are provided, and the two connecting components 12 are located on the left and right sides of the support body 11, respectively. Of course, depending on the actual situation, the two connecting components 12 in the above scheme can also be provided on the upper and lower sides, front and rear sides, etc. of the support body 11, and even more connecting components 12 can be provided, which provides high design flexibility. It can be understood that when multiple connecting components 12 are provided, the connecting arm 111 can be designed accordingly based on the number and position of the clamping parts 121.

[0047] In the above embodiments, by designing the first screw 1211 to engage with the threaded hole on the connecting arm 111, the user can control the movement of the clamping plate 1212 in the first direction by rotating the first screw 1211, thus achieving the operation of clamping the clamping plate 1212 to the external device, which is simple to operate. Furthermore, the constraint effect of the threaded engagement can effectively limit the loosening of the clamping plate 1212 along the first direction, ensuring stable clamping even in the event of vibration, resulting in high structural reliability.

[0048] In some embodiments, such as Figure 3 and Figure 4 As shown, Figure 3 The exploded view shows the components of the shock absorber assembly 13 disassembled along the first direction. Figure 4 for Figure 3 The diagram shows a cross-sectional view of the assembled components. The damping assembly 13 includes a guide sleeve 131, a guide slide rod 132, and an elastic damping element 133. The guide sleeve 131 extends along a first direction, with one end abutting against the side wall of an external device, and the other end having an opening 1311 communicating with its inner cavity. One end of the guide slide rod 132 extends into the guide sleeve 131 through the opening 1311 and is slidably connected to the guide sleeve 131, while the other end is fixedly connected to the bracket body 11.

[0049] Please continue reading. Figure 3 and Figure 4An elastic damping element 133 is disposed within the guide sleeve 131, with one end connected to the guide slide rod 132 and the other end connected to the inner wall of the guide sleeve 131. The elastic damping element 133 is a mechanical device combining an elastic element and a damper. When the elastic element is subjected to an external force and undergoes elastic deformation, it tends to recover its original deformation and thus moves. At this time, the damper can resist the movement of the elastic element through forces such as friction and fluid resistance, converting the kinetic energy of the elastic element into heat energy, thereby causing the elastic element to stop moving. Therefore, the elastic damping element 133 can both buffer external impacts through elastic deformation and dissipate the energy input from external impacts by applying resistance, causing the movement between the guide sleeve 131 and the guide slide rod 132 to stop quickly, thereby achieving a shock absorption effect.

[0050] Optionally, the connection between the elastic damping element 133 and the guide sleeve 131 can be a direct connection or an indirect connection via an intermediate component. For example, in... Figure 3 and Figure 4 In the illustrated embodiment, the elastic damping element 133 and the guide sleeve 131 can be connected via a telescopic rod 134. This design, in addition to the resistance provided by the elastic damping element 133 for vibration reduction, also enhances the vibration reduction effect by accelerating the dissipation of kinetic energy through the frictional force generated between adjacent rods when the telescopic rod 134 extends and retracts. Furthermore, since the telescopic rod 134 occupies part of the space inside the guide sleeve 131, a smaller size of elastic damping element 133 can be used, which helps save on component costs.

[0051] The above embodiment features a structure in which the guide sleeve 131 and the guide slide rod 132 are slidably connected. The inner cavity of the guide sleeve 131 defines the sliding direction of the guide slide rod 132 as a first direction and can accommodate the elastic damping element 133. This design, on the one hand, restricts the extension and retraction of the elastic damping element 133 along the first direction, and on the other hand, provides good protection for the elastic damping element 133, preventing external dust from accumulating on the elastic damping element 133 and affecting its damping performance.

[0052] In order to limit the relative rotation between the guide slider and the guide sleeve 131, in some embodiments, the cross-sectional shape of the inner cavity of the guide sleeve 131 in the direction perpendicular to the first direction is non-circular, and the shape of the guide rod 132 is the same as the shape of the inner cavity of the guide sleeve 131.

[0053] For example, Figure 3The inner cavity of the guide sleeve 131 shown is circular, extending radially to form multiple connecting grooves 1312. These grooves 1312 are arranged in a cross shape, and the guide slide rod 132 is also provided with multiple connecting blocks 1321 distributed in a cross shape. With this design, when the guide slider is inserted into the inner cavity of the guide sleeve 131, the connecting blocks 1321 abut against the inner wall of the connecting grooves 1312, thus restricting the relative rotation between the guide slider and the guide sleeve 131. Since the guide slider is fixed to the bracket body 11, and the guide sleeve 131 abuts against the side wall of the external equipment, this design effectively restricts the relative rotation between the bracket body 11 and the guide sleeve 131, which helps improve the stability of the connection structure.

[0054] It is understood that the shapes of the guide sleeve 131 and the guide slide rod 132 are not limited to the shapes in the examples above. Other non-circular shapes, such as square, elliptical or other irregular shapes, can also be used, as long as the inner cavity of the guide sleeve 131 can accommodate the elastic damping element 133 and the shape of the guide slide rod 132 is adapted to the shape of the inner cavity of the guide sleeve 131. The design is relatively flexible.

[0055] In some embodiments, such as Figure 2 As shown, at least two guide sleeves 131, guide slide rods 132, and elastic damping elements 133 are respectively arranged at intervals on a plane perpendicular to the first direction. Each guide slide rod 132 is slidably connected to a different guide sleeve 131, and each guide slide rod 132 is fixedly connected to the support body 11. Each elastic damping element 133 is disposed in a different guide sleeve 131. With this arrangement, multiple elastic damping elements 133 can work simultaneously when vibration occurs. Compared with the design of a single elastic damping element 133, the vibration buffering performance can be greatly improved, and the efficiency of consuming vibration energy can be multiplied, resulting in better shock absorption.

[0056] Please continue reading. Figure 2 The damping assembly 13 also includes damping blocks 135, which are connected to the side of each guide sleeve 131 away from the support body 11. Each guide sleeve 131 abuts against the side wall of the external equipment through the damping block 135. This design allows the same damping block 135 to transmit the vibration power to multiple guide sleeves 131 simultaneously, distributing the power more evenly to each guide sleeve 131. This ensures that the relative sliding amplitude between each guide sleeve 131 and its corresponding guide rod 132 is consistent, improving the structural stress balance.

[0057] To further improve the vibration damping performance, in some embodiments, such as Figure 2 As shown, the damping block 135 has a plurality of deformable abutment protrusions 1351 at one end that abuts against the side wall, and any two abutment protrusions 1351 are spaced apart from each other.

[0058] Optionally, only the portion of the damping block 135 that abuts the protrusion 1351 may be deformable, or the entire damping block 135 may be deformable. The arrangement of multiple abutment protrusions 1351 is not limited to the following... Figure 2 The linear arrangement shown can also be used in other ways, such as a matrix arrangement or an irregular arrangement, as long as any two abutting protrusions 1351 are spaced apart from each other. This ensures that when each abutting protrusion 1351 is deformed by compression, it can extend into the surrounding space without being restricted by adjacent abutting protrusions 1351. Furthermore, the shape of the abutting protrusions 1351 is not limited to the linear arrangement shown. Figure 2 The square shape shown can also be other shapes such as cylinders or hemispheres, allowing for more flexible design.

[0059] The above embodiment provides multiple abutment protrusions 1351. When vibration occurs, the deformation generated by the abutment protrusions 1351 can buffer the vibration, which helps to further reduce the vibration amplitude and improve the vibration damping performance of the damping component 13.

[0060] Understandably, multiple shock absorber components 13 can be provided, for example... Figure 2 Two shock-absorbing components 13 are provided, each shock-absorbing component 13 being connected to opposite sides of the support body 11 along the first direction. When multiple shock-absorbing components 13 are provided, each shock-absorbing component 13 can adopt the design of the above embodiment.

[0061] To facilitate the processing and manufacturing of the support body 11, in some embodiments, such as Figure 1 As shown, the support body 11 includes a first frame 112 and a second frame 113. The first frame 112 and the second frame 113 can be processed and formed separately, and then assembled into the support body 11 through an assembly operation. Compared with processing the support body 11 as a whole, this design allows the first frame 112 and the second frame 113 to be processed in parallel using different equipment. In some designs, the first frame 112 or the second frame 113 can also directly use ready-made profiles, eliminating some processing steps and thus improving processing efficiency.

[0062] It is understandable that when the support body 11 adopts the assembly scheme of the first frame 112 and the second frame 113, the connecting component 12 and the shock-absorbing component 13 can be set on the second frame 113, as shown in the figure. Figure 2 As shown. Of course, the connecting component 12 and the shock-absorbing component 13 can also be set on the first frame 112, and the specific design can be flexibly adjusted according to the actual situation.

[0063] Please see Figure 5(The second frame 113 is omitted in the figure). The first frame 112 and the second frame 113 enclose a mounting cavity 114 that can accommodate the component to be installed. In order to install the component into the mounting cavity 114, an opening communicating with the mounting cavity 114 can be made on the first frame 112 or the second frame 113, so that the component to be installed can be inserted through the opening. For example, in Figure 5 In the design shown, the first frame 112 has an opening 1121 for the fan body 200 of the cooling fan or other components to be installed into the mounting cavity 114. After installation, the opening 1121 can be closed by a cover plate 115. Dustproof structures such as a dustproof net 116 can also be installed at the opening 1121 to meet dustproof requirements.

[0064] To facilitate the assembly of the first frame 112 and the second frame 113, such as Figure 5 As shown, elastic blocks 1122 are respectively provided at opposite ends of the first frame 112 along the first direction, and the elastic blocks 1122 can extend and retract along the first direction. Figure 6 As shown, the second frame 113 has a plurality of snap-fit ​​holes 1131 that correspond one-to-one with the elastic snap-fit ​​block 1122 along the second direction (perpendicular to the first direction). The snap-fit ​​holes 1131 allow the elastic snap-fit ​​block 1122 in the compressed state to extend into, and the snap-fit ​​holes 1131 have a spring-loaded space 1131a extending along the first direction.

[0065] When assembling, such as Figure 5 As shown, the user can simultaneously squeeze the elastic blocks 1122 on both the upper and lower sides along the first direction to compress the elastic blocks 1122, and then move the first frame 112 closer to the second direction. Figure 6 The second frame 113, as shown, allows the elastic locking block 1122 to be pushed into the locking hole 1131. After being pushed a certain distance, the elastic locking block 1122 reaches the springback space 1131a and springs back. At this time, the free end of the elastic locking block 1122 is locked into the springback space 1131a. Under the restriction of the springback space 1131a, the elastic locking block 1122 will not disengage from the locking hole 1131 in the second direction, thus being fixed in the locking hole 1131. By performing the above operations, the user can complete the assembly of the first frame 112 and the second frame 113 without the aid of tools, making the operation simple and convenient.

[0066] Based on the requirement for reliable connection between the first frame 112 and the second frame 113, optionally, such as Figure 5 and Figure 6As shown, a second screw 1123 can be slidably inserted into the first frame 112 along the second direction, and a threaded hole 1132 is opened in the second frame 113. The connection between the second screw 1123 and the threaded hole 1132 is reinforced by the engagement of the second screw 1123 with the threaded hole 1132. Furthermore, to facilitate the rotation of the second screw 1123, a feature such as... can be provided at the head end of the second screw 1123. Figure 5 The pull ring 1123a shown allows the user to easily push, pull, or rotate the second screw 1123 without the need for tools such as screwdrivers.

[0067] In addition, to achieve positioning between the first frame 112 and the second frame 113, optionally, please refer to [further details]. Figure 5 and Figure 6 A positioning pin 1124 extending in the second direction can be provided on the first frame 112, and a corresponding positioning hole 1133 can be provided on the second frame 113. The length of the positioning pin 1124 is greater than the dimension of the elastic block 1122 in the second direction. This ensures that during assembly, the positioning pin 1124 is first inserted into the positioning hole 1133, and then the elastic block 1122 is engaged into the engagement hole 1131, thus quickly and accurately aligning the elastic block 1122 with the engagement hole 1131. Similarly, when a second screw 1123 and a threaded hole 1132 are provided, the positioning pin 1124, in conjunction with the positioning hole 1133, can also accurately align the second screw 1123 and the threaded hole 1132.

[0068] In some embodiments, such as Figure 6 As shown, a first liquid cooling pipe 14 is provided on the bracket body 11. The first liquid cooling pipe 14 is used to absorb the heat output by the component to be installed. Figure 5 As shown, a heat dissipation fin 117 is provided on the outer side of the bracket body 11, and a second liquid cooling pipe 15 is provided on the heat dissipation fin 117. One end of the second liquid cooling pipe 15 is connected to the first liquid cooling pipe 14, and the other end is used to connect to the coolant source.

[0069] Optionally, when the support body 11 adopts the assembly scheme of the first frame 112 and the second frame 113, the first liquid cooling pipe 14 can refer to Figure 6 As shown, the heat dissipation fins 117 and the second liquid cooling pipe 15 are installed on the second frame 113. Figure 5 The liquid cooling pipe 14, heat dissipation fins 117, and the liquid cooling pipe 15 are shown to be mounted on the first frame 112. Of course, in other design schemes, the positions of the first liquid cooling pipe 14, the heat dissipation fins 117, and the second liquid cooling pipe 15 can be adjusted appropriately to meet the heat dissipation requirements.

[0070] In one embodiment, the component to be installed is the fan body 200 of a cooling fan (see reference). Figure 5As shown, the fan body 200 has an air inlet and an air outlet. In external devices such as servers, the air inlet is usually oriented towards the heat-generating components inside the device to draw in air that has absorbed heat and exhaust it to the outside of the device through the air outlet. In this case, the first liquid cooling pipe 14 can be arranged near the air outlet, for example, in a position where... Figure 6 The second frame 113 shown absorbs the heat discharged from the fan body 200, which helps reduce the diffusion of heat to other components. In addition, the first liquid cooling pipe 14 can be arranged near the air inlet so that the air that has absorbed heat comes into contact with the first liquid cooling pipe 14, thereby transferring some of the heat to the first liquid cooling pipe 14 and improving the efficiency of heat dissipation and cooling.

[0071] In another implementation, the component to be installed is a hard drive. The hard drive will generate heat during use. In this case, the first liquid cooling pipe 14 can be placed close to the hard drive to quickly absorb the heat generated by the hard drive.

[0072] The above embodiment includes a liquid cooling pipe structure and heat dissipation fins 117. The first liquid cooling pipe 14 absorbs some heat, and the second liquid cooling pipe 15 passes through the heat dissipation fins 117, which assists in heat dissipation and cooling. This design enables the mounting bracket 100 to have good heat dissipation function, allowing it to cool heat-generating components in external devices or components to be installed on the mounting bracket 100, thus increasing the functional versatility of the mounting bracket 100.

[0073] This application embodiment also provides a cooling fan 1000, such as Figure 1 As shown, the cooling fan 1000 includes the aforementioned mounting bracket 100 and fan body 200 (in... Figure 1 The middle is obscured; please refer to [the relevant source]. Figure 5 As shown, the fan body 200 is mounted on the bracket body 11. The cooling fan 1000 can be connected to external devices, such as servers, switches, industrial control computers, personal computers and other network devices, through the mounting bracket 100. The fan body 200 dissipates the heat generated by the CPU, power supply and other components in the device to the outside of the device to avoid the problem of overheating of components leading to performance degradation or failure.

[0074] The cooling fan 1000 provided in this application embodiment connects the fan body 200 to equipment such as servers, switches, industrial control computers, and personal computers using a mounting bracket 100. During use, it can effectively resist external vibration and impact, and also reduce the transmission of vibration from the fan body 200 to the equipment chassis. Under vibration conditions, it always maintains a stable connection between the fan body 200 and the equipment, thereby ensuring the reliability of use.

[0075] This application embodiment also provides a network device, including the aforementioned mounting bracket 100 for the chassis, a connecting component 12 connected to the chassis, and a shock-absorbing component 13 abutting against the chassis. Optionally, the network device can be a server, switch, industrial control computer, personal computer, etc., and the aforementioned fan body 200 or hard drive can be installed on the mounting bracket 100.

[0076] The network device provided in this application embodiment uses the aforementioned mounting bracket 100 to install key components such as fans and hard drives inside the chassis. When subjected to external impacts and vibrations, the shock-absorbing components 13 on the mounting bracket 100 can quickly dissipate the vibration energy, causing the vibration to stop rapidly. The connection component 12 maintains a stable connection between the chassis and the mounting bracket 100. Therefore, this network device has good reliability.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
