[0050] As described in the background technology, the central processing unit (CPU) and memory of the network equipment need to be maintained frequently. In the related art, the air guide cover is installed above the above components, and the cables inside the network equipment are arranged above the air guide cover and cross the air guide cover. Therefore, when maintaining the above components, it is necessary to remove the cables and the air guide cover before disassembling the above components, which makes the maintenance of the network equipment difficult and increases the maintenance cost of the network equipment.

[0051] In view of this, the embodiment of the present application provides an air scoop and a network device, wherein the air scoop includes a main air scoop and a secondary air scoop that are rotatably connected. Among them, the main air scoop is movably arranged above the heat-generating components in the chassis, and the secondary air scoop is detachably installed in the chassis, and has an angle with the inner bottom wall of the chassis, and is connected by rotating the bottom end of the secondary air scoop with the connecting end of the main air scoop. The main air scoop can be switched between the first position and the second position. When the network device is working, the main air scoop is arranged in the first position, and the main air scoop and the secondary air scoop have an angle. At this time, the airflow is guided and heat is dissipated through the guide channel formed between the main air scoop and the heat-generating components in the chassis; when the network device is maintained, the main air scoop is rotated from the first position to the second position, and the main air scoop and the secondary air scoop are superimposed and connected. At this time, there is no obstruction above the heat-generating components in the chassis, and the heat-generating components in the chassis can be disassembled and assembled without removing the air scoop and cables. Therefore, the maintenance difficulty of the network device is reduced, the maintenance cost of the network device is reduced, and the maintenance efficiency of the network device is improved.

[0052] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0053] Figure 1 A partial structural diagram of the network device provided in an embodiment of the present application when the air guide cover is in the first position. Figure 2 The local structure of the network device provided in the embodiment of the present application when the air guide cover is in the second position. Figure 1 and Figure 2 As shown, an embodiment of the present application provides a network device 1, which includes but is not limited to servers, routers, switches, controllers and other devices.

[0054] The network device 1 includes a chassis 20, in which components such as a central processing unit 310 and a memory 320 are installed. The central processing unit 310 and the memory 320 can be arranged close to the inner bottom wall of the chassis. The central processing unit 310 is used to process data and tasks, and the memory 320 is used to store and cache data. The central processing unit 310 and the memory 320 have high power consumption and high heat generation.

[0055] The CPU 310 and the memory 320 can be arranged in a row and in parallel, and there is a gap between the CPU 310 and the memory 320 and the inner bottom wall of the chassis 20, which forms an installation space, and other components can be installed in the installation space. For example, components such as a motherboard can be installed between the CPU 310 and the memory 320 and the inner bottom wall of the chassis 20.

[0056] During operation, components such as the CPU 310 and the memory 320 generate a large amount of heat. Therefore, a heat sink is usually provided in the chassis to dissipate heat for the CPU 310 and the memory 320 and other heat generating components 30, thereby ensuring the normal operation of these heat generating components 30 and extending their lifespan.

[0057] The heat dissipation device may include a fan (not shown in the figure), which is reasonably installed on the chassis 20 based on factors such as space and heat dissipation efficiency. For example, the fan can be installed on the opposite side of the bottom wall of the chassis of the network device 1. In other words, the fan can be installed on the top cover of the chassis. The fan blows air toward the above-mentioned heat-generating component to accelerate the air flow speed around the heat-generating component 30 and take away the heat of the heat-generating component 30.

[0058] Continue to refer to Figure 1 and Figure 2 The heat dissipation device may further include an air guide cover 10, which is also installed in the chassis 20 of the network device. Specifically, the air guide cover 10 may be arranged above the above-mentioned heat generating component 30, and the air guide cover 10 is used to form a guide channel above the heat generating component 30. The airflow blown by the fan flows in the guide channel to accelerate the flow of the gas, so that the heat can be taken away faster, thereby improving the heat dissipation efficiency.

[0059] Reference Figure 1 or Figure 2 As shown, the network device 1 also includes a cable 40, which is mainly used to transmit data. For example, one end of the cable 40 can be connected to the input / output port of the network device 1, and the cable 40 crosses the air guide cover 10, and the other end of the cable 40 can be connected to the mainboard of the network device 1.

[0060] In this embodiment, the air scoop 10 is movably installed in the chassis 20, and the air scoop 10 has a first position and a second position. When in the first position, a guide channel is formed between the air scoop 10 and the heat generating component 30, and the gas flows through the guide channel to take away the heat of the heat generating component 30, thereby playing a role in heat dissipation. When in the second position, the air scoop 10 can be away from the heat generating component 30, and can provide a space for installation and removal of the heat generating component 30 to meet the maintenance requirements of the network device 1.

[0061] By switching the air guide cover 10 between the first position and the second position, on the basis that the air guide cover 10 can realize air diversion and heat dissipation, when the above-mentioned heat-generating component 30 needs to be replaced and repaired, the air guide cover 10 is switched from the first position to the second position, and the heat-generating component 30 can be disassembled and assembled without disassembling the air guide cover 10 and the cable 40, thereby reducing the maintenance difficulty of the network device 1 and reducing the maintenance cost of the network device 1.

[0062] Figure 3 This is a three-dimensional structural diagram of the air guide cover provided in the embodiment of the present application. Figure 3 As shown, the air scoop 10 includes a main air scoop 110 and a secondary air scoop 120, and the main air scoop 110 is rotatably connected to the secondary air scoop 120. Therefore, the main air scoop 110 can be rotated from a first position to a second position in the chassis 20. When the main air scoop 110 is in the first position, the main air scoop 110 is arranged above the heat-generating component 30 in the chassis 20, the secondary air scoop 120 is fixed in the chassis, and the secondary air scoop 120 is arranged at a certain angle to the bottom of the chassis 20, so that the air scoop 10 can guide and dissipate heat. When the main air scoop 110 rotates to the second position, the main air scoop 110 and the secondary air scoop 120 are superimposed and connected, and the air scoop 10 is not above the heat-generating component 30, so the heat-generating component 30 can be directly disassembled and assembled, and the maintenance difficulty of the network device 1 is reduced.

[0063] The main air shroud 110 is disposed above the heating component 30, and the main air shroud 110 may cover the entire area or most of the area of ​​the heating component 30. There is a gap between the main air shroud 110 and the heating component 30, and the gap forms a guide channel, through which the airflow can flow through the heating component 30 and take away the heat of the heating component 30.

[0064] During the daily operation of the network device, the auxiliary air guide cover 120 and the main air guide cover 110 are arranged at a certain angle. The auxiliary air guide cover 120 is used to block the airflow from passing through the top of the main air guide cover 110. Therefore, the airflow only passes through the guide channel formed by the main air guide cover 110 and the heat generating component 30. The airflow flowing through the guide channel increases, and more heat is taken away, thereby improving the heat dissipation efficiency of the network device 1.

[0065] Reference Figure 3As shown, one end of the main air shroud 110 is its connection end 110a, and the end of the main air shroud 110 opposite to its connection end 110a is its free end 110b. One end of the auxiliary air shroud 120 close to the bottom wall of the chassis 20 is its bottom end 120a, and the end of the auxiliary air shroud 120 opposite to its bottom end 120a is its top end 120b. The connection end 110a of the main air shroud 110 is rotatably connected to the bottom end 120a of the auxiliary air shroud 120, so as to realize the rotational connection between the main air shroud 110 and the auxiliary air shroud 120.

[0066] In one embodiment, the main air duct 110 can be arranged parallel to the bottom of the chassis 20, and the auxiliary air duct 120 can be arranged perpendicular to the bottom of the chassis 20, which is convenient for the disassembly and assembly of the air duct 10. When the network device 1 is working normally, the main air duct 110 is in the first position, and the main air duct 110 and the auxiliary air duct 120 are arranged at a 90° angle in the chassis 20.

[0067] The main air duct 110 and the auxiliary air duct 120 can be made of plastic, composite materials, aluminum alloy, etc. Exemplarily, the main air duct 110 and the auxiliary air duct 120 can be made of acrylonitrile-styrene-butadiene copolymer (ABS), which has low processing cost and good mechanical properties. In the case of plastic materials, the main air duct 110 and the auxiliary air duct 120 can be injection molded to achieve efficient and low-cost production.

[0068] The main air guide cover 110 and the auxiliary air guide cover 120 may be provided with reinforcing ribs, which can improve the strength of the main air guide cover 110 and the auxiliary air guide cover 120. Under the condition of the same strength, the main air guide cover 110 and the auxiliary air guide cover 120 are lighter in weight.

[0069] Figure 4 A three-dimensional structural diagram of the main air hood provided in an embodiment of the present application, Figure 5 The three-dimensional structure diagram of the auxiliary air guide cover provided in the embodiment of the present application is shown in FIG. Figure 4 and Figure 5 As shown, one of the main air guide cover 110 and the auxiliary air guide cover 120 is provided with a rotating shaft 111 , and the other is provided with a rotating shaft hole 121 , and the rotating shaft 111 is inserted into the rotating shaft hole 121 to realize the rotation connection between the main air guide cover 110 and the auxiliary air guide cover 120 .

[0070] In one embodiment, the rotating shaft 111 is located on the connecting end 110a of the main air guide cover 110, and the rotating shaft hole 121 is located on the bottom end 120a of the auxiliary air guide cover 120. One or more rotating shafts 111 can be provided, and one or more rotating shaft holes 121 can be provided; the rotating shafts 111 and the rotating shaft holes 121 correspond one to one, and can be provided on the left and right sides and the middle position of the connecting end 110a and the bottom end 120a. In this way, the main air guide cover 110 is subjected to balanced force during rotation and is not prone to fatigue damage.

[0071] Reference Figure 4 and Figure 5 As shown in the partial enlarged view of FIG. 1 , the end surface of the rotating shaft 111 on the main air guide cover 110 is partially cut off. The connecting surface of the auxiliary air guide cover 120 in contact with the main air guide cover 110, that is, the connecting surface around the rotating shaft hole 121, is made into a structure with an inclined angle. When the main air guide cover 110 and the auxiliary air guide cover 120 are assembled, that is, when the rotating shaft 111 is inserted into the rotating shaft hole 121, it is easier to assemble the main air guide cover 110 and the auxiliary air guide cover 120, thereby reducing the assembly stress during the assembly process.

[0072] Reference Figure 3 and Figure 4 As shown, the first avoidance opening 113 is communicated with the free end 110 b of the main airflow cover 110 , and the main airflow cover 110 may be evenly provided with two first avoidance openings 113 . The avoidance opening is mainly used to avoid the cable 40 .

[0073] Reference Figure 3 and Figure 5 As shown, the second avoidance opening 123 is connected to the top 120b of the auxiliary air duct 120. This arrangement is for easy operation when assembling the cables 40. The auxiliary air duct 120 is also evenly provided with two second avoidance openings 123 to ensure that the air duct 10 is used when there are enough cables 40.

[0074] The first avoidance opening 113 and the second avoidance opening 123 can be set to the same shape, and the first avoidance opening 113 and the second avoidance opening 123 can be set to be U-shaped. The first avoidance opening 113 and the second avoidance opening 123 are set to correspond to each other one by one. In other words, when the main air guide cover 110 and the auxiliary air guide cover 120 are overlapped, the positions of the first avoidance opening 113 and the second avoidance opening 123 overlap.

[0075] When the network device 1 is working normally, the main air guide cover 110 is located above the heat generating component 30, and the cable 40 crosses the main air guide cover 110. The main air guide cover 110 and the auxiliary air guide cover 120 are arranged at 90 degrees in the chassis 20, and the cable 40 passes through the second avoidance opening 123 of the auxiliary air guide cover 120 (see Figure 1When the heating component 30 of the network device needs to be maintained, it is necessary to remove the components above the heating component 30 and rotate the main airflow cover 110 to the second position. In this process, the cable 40 is inserted into the first avoidance opening 113, so that the cable 40 does not affect the rotation of the main airflow cover 110 (see Figure 2 shown).

[0076] Therefore, when maintaining the heating component 30, it is not necessary to disassemble the cable 40 and the air guide cover 10. This reduces the misoperation caused by disassembling the cable 40 and the air guide cover 10, improves the maintainability of the air guide cover 10, and reduces the maintenance difficulty of the heating component 30.

[0077] Reference Figure 3 As shown, one of the main air guide cover 110 and the auxiliary air guide cover 120 is provided with a buckle portion 112, and the other is provided with a buckle groove 122. When the main air guide cover 110 is rotated to the second position and the main air guide cover 110 and the auxiliary air guide cover 120 are stacked together, the buckle portion 112 can be completely snapped into the buckle groove 122 to achieve the fixation of the main air guide cover 110 in the second position.

[0078] As an example, the main air shroud 110 is provided with a buckle portion 112, and the auxiliary air shroud 120 is provided with a buckle slot 122. When the main air shroud 110 rotates to the second position, the buckle portion 112 of the main air shroud 110 is snapped into the buckle slot 122 of the auxiliary air shroud 120. As another example, the main air shroud 110 is provided with a buckle slot 122, the auxiliary air shroud 120 is provided with a buckle portion 112, and the auxiliary air shroud 120 is provided with a buckle portion 112 that is snapped into the buckle slot 122 provided on the main air shroud 110.

[0079] The buckle portion 112 and the snap-in groove 122 can be respectively provided on both sides of the main air guide cover 110 and the auxiliary air guide cover 120, and can be provided in one pair or in multiple pairs. As described above, the main air guide cover 110 can be provided with two first avoidance openings 113, and the auxiliary air guide cover 120 can be provided with two corresponding second avoidance openings 123. The buckle portion 112 can be provided on the adjacent sides of the two first avoidance openings 113, and the snap-in groove 122 can be provided on the adjacent sides of the two second avoidance openings 123. At this time, the snap-in or open operation can be completed with only one hand, which is simple, convenient and quick.

[0080] The buckle portion 112 and the clamping groove 122 may adopt a concave-convex structure. At the same time, other elastic elements may also be used to fix the main air guide cover 110, such as a buckle, a press-type lock buckle, a magnetic buckle, etc.

[0081] Reference Figure 4 and Figure 5As shown, one of the edges of the first avoidance opening 113 and the second avoidance opening 123 may include a main body 123a and an extension 123b. As an embodiment, the second avoidance opening 123 includes a main body 123a and an extension 123b. When the main air duct 110 and the auxiliary air duct 120 are stacked and connected, the extension 123b of the auxiliary air duct 120 can cover the partial area on both sides of the main body 123a. The buckle portion 112 is arranged on the adjacent sides of the two first avoidance openings 113, and the snap groove 122 is arranged on the extension 123b on both sides of the two second avoidance openings 123. When the main air duct 110 rotates to the second position, when the main air duct 110 is stacked and connected with the auxiliary air duct 120, it can be snapped with the auxiliary air duct 120, and a "click" sound can be heard when snapping, which facilitates the disassembly and assembly of the air duct 10.

[0082] Reference Figure 4 and Figure 5 As shown, the limiting portion 124 is disposed on one of the first avoidance opening 113 or the second avoidance opening 123, and is disposed on the side wall of the opening end of the first avoidance opening 113 or the second avoidance opening 123. One end of the limiting portion 124 is connected to a side wall of the opening end of the second avoidance opening 123, and the other end of the limiting portion 124 is a free end. The limiting portion 124 is used to limit the movement or winding of the cable.

[0083] In one embodiment, a limiting portion 124 is provided on both sides of the opening end of the second avoidance opening 123, and the two limiting portions 124 are arranged front and back along the thickness direction of the second avoidance opening 123. That is to say, one end of a limiting portion 124 is connected to the main body 123a, and the other end is a free end; one end of another limiting portion 124 is connected to the extension portion 123b, and the other end is a free end. In this way, the cable is limited and the threading operation is convenient. And there is a distance between the free ends of the two limiting portions 124, and this distance can pass through the cable. Exemplarily, the free end of the limiting portion 124 is designed with a large rounded corner to prevent scratches during the threading of the cable 40.

[0084] Figure 6 The partial structural diagram of the air guide cover provided in the embodiment of the present application when it is in the first position in the chassis, such as Figure 4 and Figure 6 As shown, first clamping portions 114 are provided on both sides of the main air flow cover 110, and the first clamping portions 114 are located near the free end 110b, and second clamping portions 210 are provided on the corresponding two side positions of the chassis 20. The first clamping portion 114 can be in the form of a hook, and the second clamping portion 210 can be set in the form of a long hole or a round hole, so as to facilitate the clamping of the main air flow cover 110 with the chassis.

[0085] When the network device 1 is working normally, the main air guide cover 110 is located in the first position. On the one hand, the main air guide cover 110 is connected to the second clamping portion 210 through the first clamping portion 114, and on the other hand, the main air guide cover 110 is rotatably connected to the auxiliary air guide cover 120. At this time, the main air guide cover 110 is completely fixed.

[0086] For example, one end of the first clamping portion 114 may be connected to the main air guide cover 110, and the other end of the first clamping portion 114 may be a free end, that is, there is a gap between the first clamping portion 114 and the main air guide cover 110. In this way, the first clamping portion 114 is deformed, the first clamping portion 114 is conveniently clamped with the second clamping portion 210, and the installation and removal of the main air guide cover 110 are convenient.

[0087] The first clamping portion 114 can be configured as a clamping hook and a groove opening upwards is configured on the side of the clamping hook, so that a finger can be inserted into the groove of the first clamping portion 114 to apply force, thereby facilitating the function of the first clamping portion 114 .

[0088] Limiting protrusions 115 are further provided on both sides of the main air guide cover 110 . The limiting protrusions 115 can be provided in the middle of the side faces. The limiting protrusions 115 are used to limit the main air guide cover 110 from shaking left and right in the chassis 20 .

[0089] like Figure 5 and Figure 6 As shown, the side walls of the auxiliary air duct 120 are provided with third clamping parts 125, and the third clamping parts 125 are close to the top 120b, and the corresponding positions of the side walls of the chassis 20 are provided with fourth clamping parts 220, the third clamping parts 125 can be provided with a pin, and the fourth clamping parts 220 can be provided with a corresponding hole, and the third clamping parts 125 and the fourth clamping parts 220 are clamped to limit the movement of the auxiliary air duct 120.

[0090] The third clamping portion 125 and the auxiliary air ducting cover 120 may also have a gap, which is conducive to the deformation of the third clamping portion 125, and facilitates the clamping of the third clamping portion 125 and the fourth clamping portion 220, thereby facilitating the installation and removal of the auxiliary air ducting cover 120. In addition, the third clamping portion 125 may also be designed with a small bent handle, which is convenient for grabbing when disassembling the auxiliary air ducting cover 120.

[0091] Limiting holes 126 are also provided on both sides of the auxiliary air duct cover 120, and the position of the limiting holes 126 is close to the bottom end 120a, and corresponding limiting shafts 230 are provided on both side walls of the chassis 20. The limiting holes 126 are connected with the limiting shafts 230 to limit the rotation of the auxiliary air duct cover 120 and assist in fixing the auxiliary air duct cover 120. The limiting holes 126 can also be set in a semi-open form, and the limiting shafts 230 can move in the limiting holes 126, and assist in positioning the auxiliary air duct cover 120 when the auxiliary air duct cover 120 is assembled with the chassis 20.

[0092] If the third clamping portion 125 is set as a pin and the fourth clamping portion 220 is set as a hole, the auxiliary air duct cover 120 can rotate with the fourth clamping portion 220 of the chassis 20. Therefore, after the limiting hole 126 is connected to the limiting shaft 230, the auxiliary air duct cover 120 can be completely fixed.

[0093] like Figure 6 As shown, when the network device is working normally, the first clamping part 114 and the second clamping part 210 on the main air guide cover 110 are clamped together. When the network device needs to maintain the heating component 30, pinch the groove of the first clamping part 114, and open the buckles of the first clamping part 114 and the second clamping part 210 on both sides along the direction K shown by the arrow in the figure, and rotate the main air guide cover 110 from the first position to the second position along the direction R shown by the arrow in the figure, and clamp the buckle part 112 and the clamping groove 122 together, and use the auxiliary air guide cover 120 to fix the main air guide cover 110, so that there is no component above the heating component 30, and the heating component 30 can be freely disassembled.

[0094] Figure 7 The partial structural diagram of the air guide cover in the case when the air guide cover is in the second position provided in the embodiment of the present application is as follows: Figure 7 As shown, when disassembling the air guide cover 10, it is necessary to first Figure 6 As shown, the main air duct 110 is rotated to the second position, and the auxiliary air duct 120 is used to fix the main air duct 110. At this time, the auxiliary air duct 120 and the main air duct 110 are stacked together and perpendicular to the bottom of the chassis 20. After completing the above steps, pinch the third clamping portion 125 of the auxiliary air duct 120, and push open the buckle of the third clamping portion 125 and the fourth clamping portion 220 along the direction H shown by the arrow in the figure, and continue to pinch the handle of the third clamping portion 125 and lift it along the direction N shown by the arrow in the figure, so that the limiting hole 126 is disengaged from the limiting shaft 230, and the removal of the air duct 10 is completed. In this way, the replacement of the air duct 10 can be realized very flexibly. The maintenance of the air duct 10 in the network device 1 is very convenient, which makes the application of the air duct 10 more extensive. The installation process of the air duct 10 is the opposite.
