Description

Technical Field

[0001] This invention relates to the field of core switch technology, specifically to a unidirectional airflow heat dissipation core switch. Background Technology

[0002] A core switch is not a type of switch, but rather a switch placed in the core layer (the network backbone). Core switches should all adopt a modular structure, have a considerable number of slots, and possess strong network expansion capabilities. The modular structure offers stronger performance, greater flexibility, and expandability, allowing for the selection of different numbers, speeds, and interface types of modules according to current or future needs to adapt to ever-changing network requirements.

[0003] Core switches generate significant heat during operation, which can affect their normal function. However, existing core switches typically employ multi-channel cooling, which can lead to hot air recirculation. This recirculation can cause the device to become unstable and disrupt its normal operation. Furthermore, external dust can enter the device through the ventilation windows, covering the surface of components and hindering their heat dissipation. To address these issues, we propose a unidirectional airflow cooling core switch. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a unidirectional airflow cooling core switch, comprising a protective shell, a shock-absorbing column fixedly installed at the bottom of the inner cavity of the protective shell, a housing fixedly connected to the top of the shock-absorbing column, a vent fixedly connected to the outer surface of the housing, an anti-collision rod fixedly installed on the inner surface of the protective shell, the other end of the anti-collision rod fixedly connected to the outer surface of the housing, a guide plate fixedly connected to the side of the inner surface of the housing near the vent, an exchange mesh plate fixedly connected to the bottom of the inner cavity of the housing, a vertical plate fixedly connected to the side of the exchange mesh plate near the guide plate, the other side of the vertical plate fixedly connected to the outer surface of the guide plate, heat sinks fixedly connected to the outer surface of the exchange mesh plate, and an air outlet fixedly connected to the outer surface of the housing, the air outlet penetrating the protective shell and extending to the outside of the protective shell. This device allows for a wider range of gas flow and a faster flow through the exchange mesh plate. The unidirectional airflow reduces the problem of hot air recirculation, resulting in better cooling performance.

[0005] Preferably, the shock-absorbing column includes a base plate, the bottom of which is fixedly connected to the top of the protective shell. A rotating rod is rotatably connected to the top of the base plate, and the top of the rotating rod is rotatably connected to the bottom of the shell. An elastic column is fixedly connected to the center of the top of the base plate, and a cylinder is fixedly connected to the top of the elastic column. The top of the cylinder is fixedly connected to the bottom of the shell. The shock-absorbing column can absorb the vibration transmitted from the protective shell and provide a buffer for the shell.

[0006] Preferably, the anti-collision bar includes a crossbar, the bottom of which is fixedly connected to the outer surface of the housing. A straight column is slidably connected to the outer surface of the crossbar, and a straight plate is rotatably connected to the outer surface of the straight column. One end of the straight plate near the housing is slidably connected to the outer surface of the housing, and the other side of the straight plate is slidably connected to the inner surface of the protective housing. An arc-shaped plate is fixedly connected to the outer surface of the other side of the straight plate. When the protective housing is impacted, the arc-shaped plate can bend quickly, and the bending deformation is large, which can play a good cushioning role.

[0007] Preferably, a sliding column is fixedly connected to the bottom of the straight column, the inner surface of the sliding column is slidably connected to the outer surface of the crossbar, a ring is fixedly connected to the bottom of the outer surface of the sliding column, a first spring is fixedly connected to the bottom of the sliding column, the other end of the first spring is fixedly connected to the outer surface of the shell, and an elastic plate is fixedly connected to the bottom of the ring. When the protective shell is impacted, the force transmitted from the straight plate will be absorbed by the elastic plate and the first spring, reducing the vibration of the shell.

[0008] Preferably, the vent includes a housing, the outer surface of which is fixedly connected to the outer surface of the shell, a ventilation duct is fixedly connected to the inner surface of the housing, an inclined plate is fixedly connected to the outer surface of the ventilation duct, and a filter is fixedly connected to the side of the housing near the shell. The inclined plate and the ventilation duct can block some of the larger dust particles in the gas, and the gas is then filtered through the filter to prevent dust from entering the device and affecting the normal operation of the internal components.

[0009] Preferably, the filter includes a first filter plate, the outer surface of which is fixedly connected to the inner surface of the housing. A fixing post is fixedly connected to the outer surface of the first filter plate, and second springs are fixedly connected to both sides of the fixing post. A second filter plate is fixedly connected to the other side of the second spring. The second filter plate is slidably connected to the outer surface of the first filter plate. Square filter holes are provided on the outer surfaces of both the first and second filter plates. When the airflow is large, the filtration capacity of the filter is improved, preventing dust from entering the device when the airflow is large.

[0010] Preferably, the air outlet includes a square column, which is fixedly connected to the outer surface of the housing. A limiting column is fixedly connected to the inner surface of the square column, and a blocking block is slidably connected to the inner surface of the limiting column. A rotating plate is rotatably connected to the top of the limiting column, and a cone is fixedly connected to the top of the rotating plate. The air outlet allows the gas to flow in only one direction, preventing hot air from flowing back.

[0011] Preferably, the blocking block includes a column, the outer surface of which is slidably connected to the inner surface of the limiting column, a limiting ring is fixedly connected to the top of the column, a cone is fixedly connected to the top of the limiting ring, and an elastic sheet is fixedly connected to the top of the cone. The structure of the blocking block allows gas to flow only from the inside of the device to the outside of the device and prevents it from flowing back.

[0012] This invention provides a unidirectional airflow heat dissipation type core switch. It has the following beneficial effects:

[0013] 1. This unidirectional airflow cooling core switch uses guide plates and vertical plates to allow for a wider range of airflow. When the air flows to the vertical plate, it flows along the vertical plate to every corner inside the casing. When the air is obstructed by the vertical plate, the air speed in front of the vertical plate will decrease and the pressure will increase accordingly. Under the action of pressure difference, the air accelerates along the surface of the vertical plate, and the air on both sides of the vertical plate will flow through the switching network plate faster.

[0014] 2. This unidirectional airflow cooling core switch delivers gas into the housing through ventilation openings. The gas then enters the device through inclined plates and ventilation channels. When the device is running, the inclined plates and ventilation channels can trap some larger dust particles, reducing the burden on the filter. When the device is not running, they can prevent external dust from entering the device through the ventilation openings and increasing the burden on the filter.

[0015] Third, this unidirectional airflow cooling core switch uses anti-collision bars to reduce the vibration of the switch when it is impacted. The anti-collision bar has an arc plate at the end near the shell, which has a large bending deformation and can play a better buffering role. The end near the shell has a first spring and an elastic plate. The two work together to make the change of the elastic force of the anti-collision bar smaller, thus reducing the vibration of the switch.

[0016] IV. This unidirectional airflow cooling core switch allows the airflow inside the device to flow in one direction through the air outlet. When the airflow flows out of the air outlet, the airflow pushes open the elastic sheet and flows out from the middle of the elastic sheet. When the airflow flows in from the outside, the blocking block will block the airflow. This can prevent external dust from entering the device from the air outlet and also make the airflow only flow in one direction, making the airflow more concentrated. This can prevent the hot air after cooling from flowing back and reducing the cooling efficiency. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example 1

[0030] like Figures 1-6 As shown, the present invention provides a technical solution: a unidirectional airflow heat dissipation core switch, including a protective shell 1. A shock-absorbing column 2 is fixedly installed at the bottom of the inner cavity of the protective shell 1. A shell 3 is fixedly connected to the top of the shock-absorbing column 2. A vent 4 is fixedly connected to the outer surface of the shell 3. An anti-collision rod 5 is fixedly installed on the inner surface of the protective shell 1. The other end of the anti-collision rod 5 is fixedly connected to the outer surface of the shell 3. A guide plate 6 is fixedly connected to the inner surface of the shell 3 near the vent 4. A switching network plate 7 is fixedly connected to the bottom of the inner cavity of the shell 3. A vertical plate 8 is fixedly connected to the side of the switching network plate 7 near the guide plate 6. The other side of the vertical plate 8 is fixedly connected to the guide plate 6. Heat sinks 9 are fixedly connected to the outer surface of plate 6 and the outer surface of the heat exchange plate 7. An air outlet 10 is fixedly connected to the outer surface of the housing 3. The air outlet 10 penetrates the protective housing 1 and extends to the outside of the protective housing 1. Gas is sent into the housing 3 through the ventilation port 4. The gas flows along the guide plate 6, is split when it passes the vertical plate 8, and flows along the vertical plate 8 to the heat exchange plate 7 and the heat sink 9 to cool the heat exchange plate 7. Then it flows through the housing 3 to the outside through the air outlet 10. This device makes the gas flow range wider, the speed of the gas flowing through the heat exchange plate 7 faster, and reduces the problem of hot air backflow, so that the cooling effect of the device is better.

[0031] The shock-absorbing column 2 includes a base plate 21, the bottom of which is fixedly connected to the top of the protective shell 1. A rotating rod 22 is rotatably connected to the top of the base plate 21, and the top of the rotating rod 22 is rotatably connected to the bottom of the shell 3. An elastic column 23 is fixedly connected to the center of the top of the base plate 21, and a cylinder 24 is fixedly connected to the top of the elastic column 23. The top of the cylinder 24 is fixedly connected to the bottom of the shell 3. When the shell 3 moves and vibrates, the protective shell 1 exerts an upward force on the base plate 21, and the base plate 21 exerts an upward force on the rotating rod 22 and the elastic column 23. The elastic column 23 absorbs part of the force, providing a buffer for the shell 3. The shock-absorbing column 2 can absorb the vibration transmitted from the protective shell 1 and provide protection for the shell 3.

[0032] The anti-collision bar 5 includes a crossbar 51. The bottom of the crossbar 51 is fixedly connected to the outer surface of the housing 3. A straight column 52 is slidably connected to the outer surface of the crossbar 51. A straight plate 53 is rotatably connected to the outer surface of the straight column 52. One end of the straight plate 53 near the housing 3 is slidably connected to the outer surface of the housing 3. The other side of the straight plate 53 is slidably connected to the inner surface of the protective shell 1. An arc-shaped plate 54 is fixedly connected to the outer surface of the other side of the straight plate 53. When the protective shell 1 is impacted, the protective shell 1 exerts a force on the straight plate 53. The straight plate 53 exerts a force on the straight column 52 and the arc-shaped plate 54. The arc-shaped plate 54 bends under the force, absorbing some of the kinetic energy. The anti-collision bar 5 can play a good buffering role when the protective shell 1 is impacted.

[0033] A sliding column 55 is fixedly connected to the bottom of the straight column 52. The inner surface of the sliding column 55 is slidably connected to the outer surface of the crossbar 51. A ring 56 is fixedly connected to the bottom of the outer surface of the sliding column 55. A first spring 57 is fixedly connected to the bottom of the sliding column 55. The other end of the first spring 57 is fixedly connected to the outer surface of the housing 3. An elastic plate 58 is fixedly connected to the bottom of the ring 56. When the protective housing 1 is impacted, the straight column 52 is subjected to the force transmitted from the straight plate 53, which applies pressure to the first spring 57 and the elastic plate 58. The first spring 57 is compressed by the force, and the elastic plate 58 is bent by the force, absorbing some of the kinetic energy and reducing the force on the housing 3. The force transmitted from the straight plate 53 is absorbed by the elastic plate 58 and the first spring 57, and the vibration of the housing 3 is reduced.

[0034] In use, the shock-absorbing column 2 and the anti-collision rod 5 reduce the vibration of the shell 3. When the shell 3 moves and vibrates, the protective shell 1 exerts an upward force on the base plate 21, and the base plate 21 exerts an upward force on the rotating rod 22 and the elastic column 23. The elastic column 23 absorbs part of the force and provides a buffer for the shell 3. When the protective shell 1 is impacted, the protective shell 1 exerts a force on the straight plate 53, and the straight plate 53 exerts a force on the straight column 52 and the arc plate 54. The arc plate 54 bends under the force and absorbs part of the kinetic energy. The straight column 52 applies pressure to the first spring 57 and the elastic plate 58. The first spring 57 is compressed under the force, and the elastic plate 58 bends under the force and absorbs part of the kinetic energy, thus reducing the vibration of the shell 3.

[0035] Example 2

[0036] like Figures 7-10As shown, the vent 4 includes a housing 41. The outer surface of the housing 41 is fixedly connected to the outer surface of the housing 3. A ventilation duct 42 is fixedly connected to the inner surface of the housing 41. An inclined plate 43 is fixedly connected to the outer surface of the ventilation duct 42. A filter 44 is fixedly connected to the side of the housing 41 near the housing 3. Gas enters the ventilation duct 42 through the inclined plate 43 and then flows along the ventilation duct 42 to the filter 44. After filtration, it enters the device. The inclined plate 43 and the ventilation duct 42 can block some of the larger dust particles in the gas. The gas then passes through the filter 44 to prevent dust from entering the device and affecting the normal operation of the internal components.

[0037] The filter 44 includes a first filter plate 441, the outer surface of which is fixedly connected to the inner surface of the housing 41. A fixing post 442 is fixedly connected to the outer surface of the first filter plate 441. A second spring 443 is fixedly connected to both sides of the fixing post 442. A second filter plate 444 is fixedly connected to the other side of the second spring 443. The second filter plate 444 is slidably connected to the outer surface of the first filter plate 441. Square filter holes 445 are provided on the outer surfaces of both the first filter plate 441 and the second filter plate 444. When the airflow is large, the airflow drives the second filter plate 444 to slide, and the second filter plate 444 drives the second spring 443 to compress. The square filter holes 445 on the second filter plate 444 and the first filter plate 441 overlap, thereby improving the filtration capacity of the filter 44 and preventing dust from entering the device when the airflow is large.

[0038] The air outlet 10 includes a square column 101, which is fixedly connected to the outer surface of the housing 3. A limiting column 102 is fixedly connected to the inner surface of the square column 101. A blocking block 103 is slidably connected to the inner surface of the limiting column 102. A rotating plate 104 is rotatably connected to the top of the limiting column 102. A cone 105 is fixedly connected to the top of the rotating plate 104. Gas drives the blocking block 103 to slide, the blocking block 103 drives the rotating plate 104 to rotate, and the rotating plate 104 drives the cone 105 to rotate. Gas then flows out along the blocking block 103. When the gas flows back, the cone 105 and the blocking block 103 will block the gas. The air outlet 10 makes the gas flow only in one direction, preventing hot air from flowing back.

[0039] The blocking block 103 includes a column 1031, the outer surface of which is slidably connected to the inner surface of the limiting column 102. A limiting ring 1032 is fixedly connected to the top of the column 1031, and a cone 1033 is fixedly connected to the top of the limiting ring 1032. An elastic sheet 1034 is fixedly connected to the top of the cone 1033. The airflow causes the column 1031 to slide, which in turn causes the limiting ring 1032 and the cone 1033 to slide. The cone 1033 pushes open the rotating plate 104, and the gas flows along the column 1031, pushing open the elastic sheet 1034 and flowing to the outside. When the gas flows back, the elastic sheet 1034 returns to its original position, and the gas is blocked by the elastic sheet 1034. The blocking block 103 ensures that the gas can only flow from the inside of the device to the outside of the device and cannot flow back.

[0040] In use, gas is sent into the ventilation duct 42 through the inclined plate 43. The inclined plate 43 and the ventilation duct 42 can block some of the larger dust particles in the gas. The gas flows along the ventilation duct 42 to the filter 44. After being filtered, the gas enters the device and is filtered again. The gas then flows along the guide plate 6 and the vertical plate 8 to the heat exchange plate 7 and the heat sink 9, where the heat exchange plate 7 is cooled. The gas then flows along the housing 3 from the air outlet 10. The airflow drives the column 1031 to slide. The column 1031 drives the limiting ring 1032 and the cone 1033 to slide. The cone 1033 pushes open the rotating plate 104. The rotating plate 104 drives the cone 105 to rotate. The gas flows to the outside through the column 1031, pushing open the elastic plate 1034. When the gas flows back, the elastic plate 1034 rebounds, and the blocking block 103 is driven back to its original position by the rotating plate 104. The gas is blocked by the elastic plate 1034 to prevent backflow and affect the cooling effect.

[0041] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
