[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figure 1-Figure 10 The heat dissipation chassis of outdoor communication equipment of the present invention is described.

[0032] The present invention provides a heat dissipation chassis for outdoor communication equipment, such as Figure 1 , Figure 2 and Figure 8 As shown, the heat dissipation chassis of outdoor communication equipment includes: an outer box body 1, an inner liner 3 and an inner box body 2. The outer box body 1 is formed with a cavity, and a plurality of first heat dissipation holes 11 and a plurality of second heat dissipation holes 12 are sequentially arranged along the circumference of the outer box body 1; the inner liner 3 is rotatably arranged in the cavity, and a first notch 311 is arranged on one side of the inner liner 3, and a second notch 321 is arranged on the other side of the inner liner 3; the inner box body 2 is used to arrange the communication equipment, and is arranged in the inner liner 3; during the rotation of the inner liner 3 relative to the outer box body 1, the first notch 311 is directly opposite to the first heat dissipation holes 11 at different positions on the outer box body 1, and the second notch 321 is directly opposite to the second heat dissipation holes 12 at different positions on the outer box body 1, so as to form a heat dissipation channel for the communication equipment.

[0033] In this embodiment, the outer box 1 forms a cavity for accommodating the liner 3 and the inner box 2. A plurality of first heat dissipation holes 11 arranged in sequence are provided in the circumference of the upper side of the outer box 1, and a plurality of second heat dissipation holes 12 arranged in sequence are provided in the circumference of the lower side of the outer box 1. Each first heat dissipation hole 11 and each second heat dissipation hole 12 are connected to the cavity for heat exchange with the external environment. The liner 3 is rotatably arranged in the cavity of the outer box 1, and is a key component for realizing dynamic adjustment of the heat dissipation channel. A first notch 311 is provided at the front end of the upper side of the liner 3, and a second notch 321 is provided at the rear end of the lower side of the liner 3. The first notch 311 corresponds to part of the first heat dissipation hole 11, and the second notch 321 corresponds to part of the second heat dissipation hole 12. The first notch 311 and the second notch 321 on the liner 3 are used to face the first heat dissipation hole 11 and the second heat dissipation hole 12 on the outer box 1 during the rotation process to form a heat dissipation channel. The inner box 2 is a closed structure. When in use, the communication device (not shown in the figure) can be installed inside the inner box 2. As the lining 3 rotates, the communication equipment can exchange heat with the external environment through different heat dissipation channels.

[0034] When the communication device is running, heat will be generated, and the heat dissipation of the communication device can be completed through the heat dissipation channel composed of parts such as part of the first heat dissipation hole 11, the cavity, the first notch 311, the second notch 321, and part of the second heat dissipation hole 12. If it is necessary to adjust the heat dissipation position or heat dissipation effect, the lining 3 can be controlled to rotate relative to the outer box 1 so that the first notch 311 and the second notch 321 are respectively facing the first heat dissipation hole 11 and the second heat dissipation hole 12 at different positions on the outer box 1. This dynamic adjustment can ensure that the communication device can dissipate heat through the optimal heat dissipation channel at different operating stages, thereby improving the heat dissipation efficiency.

[0035] The heat dissipation chassis for outdoor communication equipment provided by the present invention is designed with a rotatable lining 3 structure, so that the first notch 311 and the second notch 321 on the lining 3 can be respectively aligned with the first heat dissipation hole 11 and the second heat dissipation hole 12 on the outer box body 1, forming a dynamic heat dissipation channel. This design can flexibly adjust the position of the heat dissipation channel according to the working state and temperature distribution of the communication equipment, thereby achieving a more uniform and efficient heat dissipation effect, effectively reducing the temperature of the communication equipment during operation, and reducing equipment failures and performance degradation caused by overheating.

[0036] It should be noted that if Figure 1 , Figure 2 and Figure 8 As shown, the outer box body 1 can be cylindrical, the cross-section of the outer box body 1 in the horizontal direction is circular, and the cross-section of the side wall of the outer box body 1 in the vertical direction is a concave arc. The outer box body 1 is designed to be a cylindrical structure. Compared with the existing square box body, its wind resistance can be effectively improved, and the concave arc structure is designed. When the wind blows from the side to the outer box body 1, a part of the wind can be downward along the outer wall of the outer box body 1, thereby exerting a downward pressure on the outer box body 1, further improving the wind resistance of the outer box body 1, which is conducive to being installed in coastal areas and some places with strong winds.

[0037] In some embodiments, since the entire outdoor communication equipment heat dissipation chassis is set outdoors, the first heat dissipation hole 11 and the second heat dissipation hole 12 are very likely to be blocked during long-term use, and a brush strip assembly 5 is provided on the inner lining 3, which abuts against the inner wall of the outer box body 1. The brush strip assembly 5 includes a first brush strip 51 and a second brush strip 52 abutting against the inner wall of the outer box body 1; during the rotation of the inner lining 3 relative to the outer box body 1, the first brush strip 51 abuts against the first heat dissipation hole 11 at different positions, and the second brush strip 52 abuts against the second heat dissipation hole 12 at different positions, so that the first heat dissipation hole 11 and the second heat dissipation hole 12 can be automatically cleaned, effectively preventing the first heat dissipation hole 11 and the second heat dissipation hole 12 from being blocked, which is beneficial to improving the heat dissipation effect of the inner box body 2.

[0038] In this embodiment, the first brush strip 51 and the second brush strip 52 are respectively designed to clean the first heat dissipation holes 11 and the second heat dissipation holes 12. During the rotation of the liner 3, the first brush strip 51 will sequentially contact the first heat dissipation holes 11 at different positions to remove dust and debris in the holes by physical friction. Similar to the first brush strip 51, the second brush strip 52 is responsible for cleaning the second heat dissipation holes 12. Its design ensures that the second brush strip 52 can fully contact and clean different second heat dissipation holes 12 in each rotation of the liner 3.

[0039] The number of the first heat dissipation holes 11 and the second heat dissipation holes 12 can be increased or decreased as needed. Since there are many mosquitoes outdoors, in actual use, generally only an appropriate number of first heat dissipation holes 11 and second heat dissipation holes 12 are required. If the number of the first heat dissipation holes 11 and the second heat dissipation holes 12 is too large, the probability of mosquitoes entering the outer box body 1 will be greatly increased, and the mosquitoes that have entered will be difficult to remove. In the long run, the mosquitoes will accumulate in the outer box body 1, which will affect the rotation of the lining 3 and is not conducive to the maintenance of the communication equipment.

[0040] In some embodiments, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the liner 3 includes: a first liner frame 31 and a second liner frame 32. The first liner frame 31 is arranged in the cavity, a first notch 311 is formed on one side, a first baffle 312 is arranged on the other side, and a first brush strip 51 is arranged on the first baffle 312. The second liner frame 32 is arranged in the cavity, the second liner frame 32 is connected to the first liner frame 31, a second notch 321 is formed on one side of the second liner frame 32, a second baffle 322 is arranged on the other side, and a second brush strip 52 is arranged on the second baffle 322. The first notch 311 is connected to a part of the first heat dissipation hole 11, and the first baffle 312 blocks another part of the first heat dissipation hole 11, and the second notch 321 is connected to a part of the second heat dissipation hole 12, and the second baffle 322 blocks another part of the second heat dissipation hole 12.

[0041] In this embodiment, the first liner frame 31 is arranged in the cavity of the chassis, and a first notch 311 is provided on one side thereof, which is used to communicate with the first heat dissipation hole 11 during the rotation process to form a heat dissipation channel. A first baffle 312 is provided on the other side to block part of the first heat dissipation hole 11, so as to flexibly adjust the heat dissipation area according to the heat dissipation requirements of the communication equipment. The second liner frame 32 is also arranged in the cavity of the chassis and connected to the first liner frame 31. A second notch 321 is formed on one side thereof, which is used to communicate with the second heat dissipation hole 12 during the rotation process to form a heat dissipation channel. A second baffle 322 is provided on the other side to block part of the second heat dissipation hole 12 to achieve fine control of the heat dissipation area.

[0042] When the first liner frame 31 and the second liner frame 32 rotate, the first brush strip 51 will conflict with different first heat dissipation holes 11, and the second brush strip 52 will conflict with different second heat dissipation holes 12. The first brush strip 51 will clean the first heat dissipation holes 11, and the second brush strip 52 will clean the second heat dissipation holes 12. The physical friction principle is used to automatically remove dust and debris in the holes to ensure that the heat dissipation channel is unobstructed. In addition, the dynamic adjustment of the heat dissipation channel is achieved through the coordinated rotation of the first liner frame 31 and the second liner frame 32. The first notch 311 and the second notch 321 can be respectively opposite to different first heat dissipation holes 11 and second heat dissipation holes 12, so as to form the best heat dissipation channel layout according to the heat dissipation requirements of the communication equipment.

[0043] Generally, the first notch 311 and the second notch 321 are staggered in the rotation direction of the inner liner 3. By staggering the first notch 311 and the second notch 321, an air inlet and an air outlet channel can be formed, and by setting the first baffle 312 and the second baffle 322, a part of the first heat dissipation hole 11 and the second heat dissipation hole 12 can be respectively blocked, and by rotating the inner liner 3, the first notch 311 can face the first heat dissipation hole 11 at different positions, and the second notch 321 can face the second heat dissipation hole 12 at different positions, so as to achieve a full range of heat dissipation functions, so that under the premise of satisfying the heat dissipation of the inner box 2, some mosquitoes are blocked from entering the outer box 1.

[0044] In some embodiments, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in order to achieve control of the lining 3, the outdoor communication equipment heat dissipation chassis includes: a drive component 4, a rotating shaft 35 is provided on the lining 3, and the drive component 4 is transmission-connected with the rotating shaft 35, so that the drive component 4 drives the lining 3 to rotate relative to the outer box body 1 through the rotating shaft 35.

[0045] In this embodiment, the outer box body 1 is a cylindrical structure, so the liner 3 can rotate along the inner wall of the outer box body 1 through a driving mechanism. A rotating shaft 35 is provided on the inner liner 3. The rotating shaft 35 passes through the upper part of the outer box body 1 and the protruding end is connected to the driving assembly 4. The rotating shaft 35 is connected to the outer box body 1 through a bearing.

[0046] Specifically, the lining 3 includes a first lining frame 31 and a second lining frame 32, the first lining frame 31 and the second lining frame 32 are connected by a plurality of first connecting ribs 33, the rotating shaft 35 is connected to the first lining frame 31 by a plurality of second connecting ribs 34, the first lining frame 31 is located on the inner side of the first heat dissipation hole 11, the second lining frame 32 is located on the inner side of the second heat dissipation hole 12, the first lining frame 31 is provided with a first notch 311 and a first baffle 312, the first notch 311 is connected to a part of the first heat dissipation hole 11, the first baffle 312 can cover another part of the first heat dissipation hole 11, the second lining frame 32 is provided with a second notch 321 and a second baffle 322, the second notch 321 is connected to a part of the second heat dissipation hole 12, the second baffle 322 can cover another part of the second heat dissipation hole 12.

[0047] When the position of the liner 3 needs to be adjusted, the drive assembly 4 is started and the power is transmitted to the shaft 35 through the transmission device. The shaft 35 drives the liner 3 (the first liner frame 31 and the second liner frame 32) to rotate relative to the outer box 1, and the corresponding first heat dissipation holes 11 and second heat dissipation holes 12 on the liner 3 change accordingly, thereby optimizing the heat dissipation effect. When the desired position is reached, the drive assembly 4 stops working and the liner 3 remains in the current position.

[0048] In one example, if Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the driving assembly 4 adopts a fan blade group, including: an annular sleeve 43 and two wind shields 41. The annular sleeve 43 is connected to the rotating shaft 35, and the two wind shields 41 are arranged on the annular sleeve 43 at a certain angle.

[0049] Specifically, the annular sleeve 43 is fixed to the outside of the rotating shaft 35, and there are two windshield plates 41. The windshield plates 41 are connected to the annular sleeve 43 through a connecting plate 42. The outer wall of the liner 3 is provided with a first brush strip 51 and a second brush strip 52. The first brush strip 51 and the second brush strip 52 are respectively opposite to the first heat dissipation hole 11 and the second heat dissipation hole 12. The first brush strip 51 and the second brush strip 52 abut against the inner wall of the outer box body 1. The inner liner 3 is rotated to drive the first brush strip 51 and the second brush strip 52 to rotate. When the external wind force is large, the wind can push the windshield plate 41, so that the inner liner 3 can be rotated. When the inner liner 3 rotates, the first brush strip 51 and the second brush strip 52 can rotate along the inner wall of the outer box body 1, so that the first heat dissipation hole 11 and the second heat dissipation hole 12 can be automatically cleaned, effectively preventing the first heat dissipation hole 11 and the second heat dissipation hole 12 from being blocked, which is conducive to improving the heat dissipation effect of the inner box body 2.

[0050] To ensure the effect of controlling the rotation of the liner 3, the angle between the two windshields 41 is 110 to 160 degrees. That is, the angle a on the front of the two windshields 41 is 200° to 250°, preferably 230°, and the angle b on the back of the two windshields 41 is 110° to 160°, preferably 130°. The angle a is on the same side as the first notch 311, and the angle b is on the same side as the second notch 321. The windshield 41 is located on one side of the angle as an arc surface 411.

[0051] When the wind blows toward the outer box 1, since the angle of angle a is greater than the angle of angle b, the stability of the side of angle a is greater than the stability of the side of angle b, so the side of angle a will rotate to the windward side, so that the first notch 311 can be on the windward side, and the second notch 321 is on the leeward side. The outside wind enters the outer box 1 from the first heat dissipation hole 11 opposite to the first notch 311, passes through the first notch 311, the lining 3, the surface of the inner box 2, the second notch 321 in sequence, and finally flows out from the second heat dissipation hole 12 opposite to the second notch 321. When the wind force is sufficient to blow the lining 3 to rotate, the first notch 311 can always be on the windward side, and the second notch 321 can always be on the leeward side, so that the heat dissipation capacity can be effectively guaranteed to be optimal, the heat dissipation effect is improved, and the use of wind as a power source to drive the rotation of the lining 3 is more energy-saving and environmentally friendly.

[0052] In one example, if Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the outer box body 1 is provided with a plurality of first drainage holes 13 and a plurality of second drainage holes 14 which are arranged in sequence along its circumference; the first brush strips 51 are provided on both sides of the first baffle plate 312, and the second brush strips 52 are provided on both sides of the second baffle plate 322; the first liner frame 31, the first baffle plate 312, the two first brush strips 51 and the inner wall of the outer box body 1 form a first cavity; the second liner frame 32, the second baffle plate 322, the two second brush strips 52 and the inner wall of the outer box body 1 form a second cavity; during the rotation of the liner 3 relative to the outer box body 1, the first cavity is communicated with the first drainage holes 13 at different positions, and the second cavity is communicated with the second drainage holes 14 at different positions.

[0053] Specifically, the first annular rib 36 and the second annular rib 37 are respectively provided on the outer side of the first liner frame 31, the first notch 311 and the first heat dissipation hole 11 are located between the first annular rib 36 and the second annular rib 37, the third annular rib 38 and the fourth annular rib 39 are respectively provided on the outer side of the second liner frame 32, the second notch 321 and the second heat dissipation hole 12 are located between the third annular rib 38 and the fourth annular rib 39, the first annular rib 36, the second annular rib 37, the third annular rib 38 and the fourth annular rib 39 are respectively abutted against the inner wall of the outer box body 1, the first brush strip 51 is fixed to the outer wall of the first baffle 312, the first brush strip 51 is located on both sides of the first notch 311, and the first The two ends of the brush strip 51 are respectively connected to the first annular rib 36 and the second annular rib 37, the second brush strip 52 is fixed to the outer wall of the second baffle 322, the second brush strip 52 is located on both sides of the second notch 321, the two ends of the second brush strip 52 are respectively connected to the third annular rib 38 and the fourth annular rib 39, the first brush strip 51 and the second brush strip 52 respectively abut against the inner wall of the outer box body 1, and a plurality of circumferentially distributed first drainage holes 13 and second drainage holes 14 are respectively provided on the outside of the outer box body 1, the first drainage hole 13 is located on the outside of the second annular rib 37, the second drainage hole 14 is located on the outside of the fourth annular rib 39, and the first drainage hole 13 and the second drainage hole 14 are arranged obliquely downward from the inside to the outside.

[0054] The first baffle plate 312, the two first brush strips 51, the inner wall of the outer box body 1, the first annular rib 36 and the second annular rib 37 can form an independent first cavity; the second baffle plate 322, the two second brush strips 52, the inner wall of the outer box body 1, the third annular rib 38 and the fourth annular rib 39 can also form an independent second cavity. Through the above design, when mosquitoes enter from the first heat dissipation hole 11 directly opposite to the first baffle plate 312 or from the second heat dissipation hole 12 directly opposite to the second baffle plate 322, the mosquitoes can only enter the first cavity or the second cavity. The first brush strip 51 and the second brush strip 52 can also hit mosquitoes when the lining 3 rotates, and the bodies of the mosquitoes can be discharged to the outside from the first drainage hole 13 or the second drainage hole 14; when rainwater enters the inner wall of the outer box body 1 from the first heat dissipation hole 11 or the second heat dissipation hole 12, the second annular rib 37 and the fourth annular rib 39 can both block the rainwater, and the rainwater can be discharged to the outside from the first drainage hole 13 or the second drainage hole 14, effectively preventing water accumulation inside the outer box body 1.

[0055] In addition, a first reinforcing rib 313 is provided in the middle of the first notch 311, and the two ends of the first reinforcing rib 313 are respectively connected to the upper and lower surfaces of the first notch 311; a second reinforcing rib 323 is provided in the middle of the second notch 321, and the two ends of the second reinforcing rib 323 are respectively connected to the upper and lower surfaces of the second notch 321. By arranging the first reinforcing rib 313 and the second reinforcing rib 323, the overall structural strength of the lining 3 can be effectively guaranteed.

[0056] In some embodiments, in some areas where the wind is not strong enough to push the liner 3, such as Fig. 9 and Fig.10 As shown, the driving assembly 4 includes: a motor 8, a first gear 81 and a second gear 9. The first gear 81 is connected to the driving end of the motor 8; the second gear 9 is meshed with the first gear 81 and connected to the rotating shaft 35. A support frame 17 is provided on the upper part of the outer box body 1, the motor 8 is fixed to the support frame 17, a first gear 81 is provided at the end of the driving shaft of the motor 8, a second gear 9 is fixed to the outside of the rotating shaft 35, the first gear 81 is meshed with the second gear 9, a shell 7 is provided on the upper part of the outer box body 1, and the first gear 81 and the second gear 9 are located in the shell 7. When it is necessary to clean the first heat dissipation hole 11 and the second heat dissipation hole 12, the motor 8 can drive the lining 3 to rotate, thereby realizing the cleaning of the first heat dissipation hole 11 and the second heat dissipation hole 12.

[0057] In some embodiments, Figure 3 and Figure 4 As shown, the first heat dissipation hole 11 and / or the second heat dissipation hole 12 are arranged downwardly from the outside to the inside. In a specific example, only the second heat dissipation hole 12 is arranged downwardly from the outside to the inside. Through this design, it can also play a role in guiding rainwater, and the second heat dissipation hole 12 is cleaned by rainwater, which further prevents the second heat dissipation hole 12 from being blocked, and the rainwater that enters can flow out from the second drainage hole 14.

[0058] In some embodiments, Figure 3 and Figure 4 As shown, the first heat dissipation hole 11 and / or the second heat dissipation hole 12 include: a first through hole 111 and a second through hole 112 that are interconnected; the first through hole 111 is located on the outside of the second through hole 112, the first through hole 111 is arranged to be inclined downward from the outside to the inside, and the radius of the second through hole 112 gradually increases from the outside to the inside.

[0059] In a specific example, only the first heat dissipation hole 11 includes a first through hole 111 and a second through hole 112 that are interconnected. The first through hole 111 is located outside the second through hole 112. The first through hole 111 is designed to be inclined downward from the outside to the inside, and the second through hole 112 is a tapered hole whose cross-section gradually increases from the outside to the inside. By setting the first through hole 111, rainwater can be diverted on rainy days so that rainwater can smoothly enter the first through hole 111. By diverting the rainwater, the first heat dissipation hole 11 can also be dredged, further preventing the probability of the first heat dissipation hole 11 being blocked. After passing through the first heat dissipation hole 11, the rainwater can flow down along the inner wall of the outer box body 1 and finally be discharged from the first drainage hole 13. The rainwater will not accumulate in the outer box body 1. By setting the second through hole 112, it can play a wind guiding role, facilitate the diffusion of wind entering the outer box body 1, and improve the heat dissipation effect of the inner box body 2.

[0060] In some embodiments, Figure 2and Figure 5 As shown, the heat dissipation chassis of the outdoor communication equipment also includes: a drawer box 6; the top of the drawer box 6 is provided with an opening, the bottom of the inner box body 2 is provided with a mounting groove 23 suitable for accommodating the drawer box 6, and the bottom of the outer box body 1 is provided with a mounting hole 15 corresponding to the mounting groove 23; the drawer box 6 passes through the mounting hole 15 and is slidably set in the mounting groove 23.

[0061] Specifically, a plurality of mounting holes 15 are provided on the peripheral side near the bottom of the outer box body 1, and the number of the mounting holes 15 is four. A drawer 6 is installed in the mounting holes 15. The inner box body 2 includes a base 21, and a plurality of mounting grooves 23 are provided on the side of the base 21. The drawer 6 includes a box body 61 and a cover plate 62. The box body 61 can be inserted into the mounting groove 23. A magnet 64 is installed on the outer side of the box body 61, and the magnet 64 can be attracted to the outer wall of the inner box body 2. The cover plate 62 can cover the mounting groove 23. A guide platform 22 is provided on the upper part of the base 21. The guide platform 22 is located above the box body 61. The guide platform 22 is arranged to be inclined downward from the center of the inner box body 2 to the surrounding areas. A third drainage hole 63 is provided between the bottom of the drawer box 6 and the cover plate 62. The bottom of the drawer box 6 is arranged to be inclined downward from the inside to the outside.

[0062] Since dust and mosquitoes will inevitably enter the outer box 11, a pull-out drawer 6 is provided, so that dust, dead mosquitoes and the like will accumulate in the drawer 6. At this time, the inside of the outer box 1 can be cleaned by simply pulling out the drawer 6, which is easy to operate. When the communication equipment inside the inner box 2 is working, heat will be generated, and water droplets will condense on the outer wall of the inner box 2. When the water droplets drip, they can also enter the drawer 6 and finally be discharged to the outside from the third drainage hole 63, thereby effectively avoiding water accumulation inside the outer box 1.

[0063] Since dust and mosquitoes will inevitably enter the interior of the outer box 1, a pull-out drawer 6 is provided, and dust, dead mosquitoes and the like will accumulate in the drawer 6. At this time, the interior of the outer box 1 can be cleaned by simply pulling out the drawer 6, which is easy to operate. When the communication equipment inside the inner box 2 is working, heat will be generated, and water droplets will condense on the outer wall of the inner box 2. When the water droplets drip, they can also enter the drawer 6 and finally be discharged to the outside from the third drainage hole 63, thereby effectively avoiding water accumulation inside the outer box 1.

[0064] like Figure 6 and Figure 7 As shown, a spacing area 16 is formed between two adjacent drawers 6, and a stopper 25 corresponding to the spacing area 16 is provided on the side of the inner box body 2. The stopper 25 can cover the upper part of the spacing area 16. Through this design, dust, mosquito corpses and water accumulation inside the outer box body 1 can be further avoided.

[0065] In some embodiments, Figure 2 and Figure 8As shown, a avoidance hole 351 is provided inside the rotating shaft 35, and a signal line 24 is provided on the upper part of the inner box 2. The signal line 24 can pass through the avoidance hole 351 and be exposed to the outside, thereby facilitating signal transmission of the communication device inside the inner box 2. It can be understood that the specification and number of the avoidance holes 351 can be adjusted according to actual needs.

[0066] In some embodiments, Figure 1 , Figure 2 and Figure 8 As shown, the outer box 1 is located at the outermost layer, and is designed with a structure with an opening at the bottom, which is convenient for overall lifting and disassembly. The lining 3 is located between the outer box 1 and the inner box 2, and is also designed with an opening at the bottom, mainly for protection and support. The inner box 2 is the innermost layer, accommodating the communication equipment, and its design allows it to be directly exposed after removing the outer box 1 and the lining 3, which is convenient for maintenance.

[0067] When maintenance is required, the operator will first pull out all the drawers 6 installed in the inner box 2. Then, by grabbing the upper part of the outer box 1 or the preset lifting point, the operator can easily pull the entire outer box 1 upward. Since the lower part of the outer box 1 is designed to be open, it can be easily separated from the lining 3 during the pulling process without being hindered. When the outer box 1 is completely pulled up and removed, the lining 3 will be exposed. Since the lining 3 is also designed to be open at the bottom and the cover is arranged on the outside of the inner box 2, the lining 3 can also be quickly removed with just a slight lift. At this time, the inner box 2 is completely exposed, and the operator can freely access and maintain the communication equipment therein, such as replacing parts, checking lines, or performing necessary cleaning work.

[0068] In summary, the outdoor communication equipment heat dissipation chassis provided by the present application has the following beneficial effects: 1. The outer box body 1 is cylindrical, the horizontal cross-section of the outer box body 1 is circular, and the cross-section of the side wall of the outer box body 1 in the vertical direction is a concave arc. Compared with the existing square box body, it can effectively improve its wind resistance. In addition, the concave arc structure is designed. When the wind blows from the side to the outer box body 1, a part of the wind can go down along the outer wall of the outer box body 1, thereby exerting a downward pressure on the outer box body 1, further improving the wind resistance of the outer box body 1, which is conducive to being installed in coastal areas and some places with strong winds.

[0069] 2. When the external wind is strong, the wind can push the wind shield 41, so that the lining 3 can rotate. When the lining 3 rotates, the brush strip assembly 5 can rotate along the inner wall of the outer box 1, so as to automatically clean the first heat dissipation holes 11 and the second heat dissipation holes 12, effectively preventing the first heat dissipation holes 11 and the second heat dissipation holes 12 from being blocked, which is beneficial to improving the heat dissipation effect of the inner box 2.

[0070] 3. By setting the first notch 311 and the second notch 321, an air inlet and an air outlet channel can be formed. By setting the first baffle 312 and the second baffle 322, a part of the first heat dissipation hole 11 and the second heat dissipation hole 12 can be respectively blocked. By rotating the liner 3, the first notch 311 can face the first heat dissipation hole 11 at different positions, and the second notch 321 can face the second heat dissipation hole 12 at different positions, thereby realizing a full range of heat dissipation function, so that under the premise of meeting the heat dissipation of the inner box body 2, some mosquitoes are blocked from entering the outer box body 1.

[0071] 4. When the wind blows toward the outer box body 1, since the angle a is greater than the angle b, the stability of the side of angle a is greater than the stability of the side of angle b, so the side of angle a will rotate to the windward side, so that the first notch 311 can be on the windward side and the second notch 321 is on the leeward side. The outside wind enters the outer box body 1 from the first heat dissipation hole 11 opposite the first notch 311, passes through the first notch 311, the lining 3, the surface of the inner box body 2, and the second notch 321 in turn, and finally flows out from the second heat dissipation hole 12 opposite the second notch 321. When the wind force is sufficient to blow the lining 3 to rotate, the first notch 311 can always be on the windward side and the second notch 321 can always be on the leeward side, thereby effectively ensuring the optimal heat dissipation capacity and improving the heat dissipation effect. In addition, using wind as a power source to drive the rotation of the lining 3 is more energy-saving and environmentally friendly.
