Description

Technical Field

[0001] This utility model relates to the field of network cabinet technology, specifically to a network cabinet with a high-efficiency heat dissipation structure. Background Technology

[0002] A network cabinet is a mounting box used to assemble and install panels, plug-ins, boxes, electronic components, devices, and mechanical parts and components to form a whole. Depending on the type, there are server cabinets, wall-mounted cabinets, network cabinets, standard cabinets, intelligent protective outdoor cabinets, etc.

[0003] In the existing technology, since the cabinet will generate a lot of heat when it is running, a heat dissipation device needs to be installed to dissipate heat. However, in order to prevent external dust from entering the cabinet during the heat dissipation process, a dustproof mesh is installed to block the dust. However, after a period of use, the dustproof mesh becomes blocked by dust, which will seriously affect the heat dissipation performance of the cabinet. In order to ensure the normal ventilation and heat dissipation of the dustproof mesh, it is often necessary to clean it manually, but manual cleaning is too troublesome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a network cabinet with a high-efficiency heat dissipation structure, which solves the problems of inconvenient cleaning and impaired heat dissipation performance after the high-speed dustproof mesh is blocked by dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a network cabinet with a high-efficiency heat dissipation structure, comprising a cabinet body and at least two cooling fans, wherein the cooling fans are all installed at the bottom of the cabinet body;

[0006] The cabinet has a heat dissipation vent on the left side, with an annular groove on the inner wall of the vent, and a dustproof mesh plate extending into the annular groove inside the vent. A concave mesh cover is fixed to the right inner wall of the cabinet, and a motor is fixed to the inner side wall of the concave mesh cover. A timer switch is installed on the motor, and a shaft tube is connected to the motor's power end. A bushing is fitted around the shaft tube, and the bushing is fixedly inserted through the middle of the dustproof mesh plate. A cleaning brush and a dust inlet pipe are arranged sequentially from left to right on the left side of the dustproof mesh plate. At least two spring pressure rods are connected between the cleaning brush and the dust inlet pipe, and the dust inlet pipe is connected to the shaft tube.

[0007] A vacuum cleaner is fixed to the upper part of the cabinet. The vacuum cleaner's suction port is connected to a suction pipe. The front and rear ends of the suction pipe are connected to several suction hoods with openings facing the dustproof mesh plate. The left end of the suction pipe is rotatably connected to and communicates with the suction pipe.

[0008] Several spring return rods arranged in a ring are fixed on the left side of the dustproof mesh plate. The left end of the spring return rods is connected to the left wall of the annular groove. A shaking drive assembly is provided on the right side of the dustproof mesh plate.

[0009] Preferably, a perforated support plate fixed inside the cabinet is provided above the cooling fan.

[0010] Preferably, both the vacuum cleaner and the motor are connected in series with a timer switch.

[0011] Preferably, the inner wall of the concave mesh cover is connected with several heat sinks.

[0012] Preferably, the dustproof mesh plate has two exhaust fan blades on the right side, and the exhaust fan blades are fixed to the upper and lower ends of the shaft tube.

[0013] Preferably, an annular spacer is connected between the left side of the dustproof mesh and the left wall of the annular groove, and the annular spacer is made of elastic rubber.

[0014] Preferably, the vibration drive assembly includes a semi-circular protrusion and a spherical impact block, with two of each type. The semi-circular protrusion is fixed to the right side of the dustproof mesh plate, and the spherical impact block is fixed to the upper and lower ends of the shaft tube. The arc surface of the spherical impact block corresponds to the arc surface of the semi-circular protrusion.

[0015] This utility model provides a network cabinet with a high-efficiency heat dissipation structure, which has the following beneficial effects:

[0016] The motor and vacuum cleaner are automatically turned on and off via a timer switch. When the motor is working, it automatically drives the cleaning brush to clean the dust on the left side of the dust filter. The spherical impact block continuously strikes the semi-circular protrusion, and combined with the spring return rod, this causes the dust filter to vibrate back and forth, effectively shaking off the dust and ensuring a more thorough cleaning. The vacuum cleaner then absorbs the cleaned dust through its suction hood, preventing it from re-adhering to the dust filter. In summary, this system automatically cleans and unclogs the dust filter, effectively reducing the hassle of manual cleaning and ensuring proper ventilation and heat dissipation within the cabinet. Combined with the operation of the cooling fan, this makes heat dissipation even more efficient. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a network cabinet with a high-efficiency heat dissipation structure, including a cabinet body 1 and at least two cooling fans 3. The cooling fans 3 are all installed at the bottom inside the cabinet body 1. A heat dissipation vent 4 is opened on the left side of the cabinet body 1. An annular groove 6 is opened on the inner wall of the heat dissipation vent 4, and a dustproof mesh plate 5 extending into the annular groove 6 is provided inside the heat dissipation vent 4. A concave mesh cover 18 is fixed to the inner right wall of the cabinet body 1, and a motor 16 is fixed to the inner side wall of the concave mesh cover 18. A timer switch 17 is installed on the 6, and a shaft tube 11 is connected to the power end of the motor 16. A bushing 20 is sleeved around the shaft tube 11. The bushing 20 is fixedly inserted through the middle of the dustproof mesh plate 5. A cleaning brush 13 and a dust inlet pipe 12 are arranged sequentially from left to right on the left side of the dustproof mesh plate 5. At least two spring pressure rods 14 are connected between the cleaning brush 13 and the dust inlet pipe 12. The dust inlet pipe 12 is connected to the shaft tube 11. The vacuum cleaner 9 and the motor 16 are both connected in series with the timer switch 17.

[0025] The motor 16 and vacuum cleaner 9 are turned on and off by a timer switch 17. For example, the timer switch 17 is turned on once every other day, and the start time is set to be turned off after 10 minutes (the specific start and stop time is set according to the specific situation). When the motor 16 is working, it can automatically drive the shaft tube 11, dust inlet tube 12, spring pressure rod 14 and cleaning brush 13 to rotate together. The elasticity of the spring pressure rod 14 can drive the cleaning brush 13 to press tightly against the left side of the dust screen plate 5, which is conducive to the cleaning brush 13 making close contact with the left side of the dust screen plate 5. Therefore, when the cleaning brush 13 rotates, it will automatically sweep and clean the dust on the left side of the dust screen plate 5, which helps to reduce the trouble of manually cleaning the dust screen plate 5.

[0026] In this embodiment, a number of spring return rods 7 arranged in a ring are fixed on the left side of the dustproof mesh plate 5. The left end of the spring return rods 7 is connected to the left wall of the annular groove 6. A shaking drive assembly is provided on the right side of the dustproof mesh plate 5. The shaking drive assembly includes a semi-circular protrusion 21 and a spherical impact block 22. There are two of each semi-circular protrusion 21 and spherical impact block 22. The semi-circular protrusion 21 is fixed on the right side of the dustproof mesh plate 5. The spherical impact block 22 is fixed at the upper and lower ends of the shaft tube 11. The arc surface of the spherical impact block 22 corresponds to the arc surface of the semi-circular protrusion 21.

[0027] Furthermore, when the shaft tube 11 rotates, it will cause the spherical impact block 22 to rotate as well. Therefore, the spherical impact block 22 continuously impacts the semi-circular protrusion 21. During this process, the spherical impact block 22 will continuously push the semi-circular protrusion 21 to the left through the arc surface. The semi-circular protrusion 21 will push the dustproof mesh plate 5 to the left. At the same time, the dustproof mesh plate 5 will compress the spring return rod 7. Combined with the elasticity of the spring return rod 7, it will drive the dustproof mesh plate 5 to move to the right. In summary, this process is repeated, which can drive the dustproof mesh plate 5 to shake back and forth from left to right. The dustproof mesh plate 5 will also drive the bushing 20 to move left and right around the shaft tube 11. Therefore, it is beneficial to shake off the dust on the dustproof mesh plate 5 and to clean the dust on the dustproof mesh plate 5 more cleanly and thoroughly.

[0028] In this embodiment, an annular spacer 8 is connected between the left side of the dustproof mesh plate 5 and the left inner wall of the annular groove 6, and the annular spacer 8 is made of elastic rubber.

[0029] By setting an elastic rubber ring-shaped partition 8 between the left side of the dustproof mesh plate 5 and the left wall of the annular groove 6, when the dustproof mesh plate 5 shakes back and forth, the dustproof mesh plate 5 will stretch or compress the annular partition 8, which helps to ensure the normal movement of the dustproof mesh plate 5 and also prevents external dust from entering the cabinet 1 through the annular groove 6.

[0030] In this embodiment, a vacuum cleaner 9 is fixed at the upper end of the cabinet 1. The vacuum cleaner 9 has a vacuum pipe 10 connected to its suction port. The front and rear ends of the dust inlet pipe 12 are connected to a number of vacuum hoods 15 with openings facing the dustproof mesh plate 5. The left end of the dust inlet pipe 12 is rotatably connected to and communicates with the vacuum pipe 10. A mesh support plate 2 fixed inside the cabinet 1 is provided above the cooling fan 3.

[0031] Furthermore, after the vacuum cleaner 9 is started, it will absorb the dust collected through the dust hood 15. The dust absorbed by the dust hood 15 is then sucked into the vacuum cleaner 9 through the dust inlet pipe 12, shaft pipe 11, and suction pipe 10, thereby preventing the dust from adhering to the dustproof mesh plate 5 again. In summary, this facilitates automatic cleaning and unblocking of the dustproof mesh plate 5, effectively reducing the trouble of manual cleaning of the dustproof mesh plate 5. It also helps to ensure the ventilation and heat dissipation performance inside the cabinet 1. Combined with the operation of the cooling fan 3, the cooling air blows from bottom to top into the cabinet 1 through the mesh support plate 2, and finally exhausts the heat through the heat dissipation vent 4, making the heat dissipation effect more efficient.

[0032] In this embodiment, two exhaust fan blades 19 are provided on the right side of the dustproof mesh plate 5, and the exhaust fan blades 19 are fixed to the upper and lower ends of the shaft tube 11.

[0033] During the dust cleaning process, the shaft tube 11 will drive the exhaust fan blades 19 to rotate together. When the exhaust fan blades 19 rotate, they can not only accelerate the speed at which the heat inside the cabinet 1 is discharged through the heat dissipation port 4, but also blow the dust out of the heat dissipation port 4, which helps to better prevent the cleaned dust from adhering to the dustproof mesh plate 5 again.

[0034] In this embodiment, several heat sinks 23 are connected to the inner sidewall of the concave mesh cover 18.

[0035] By setting multiple heat sinks 23 inside the concave mesh cover 18, the heat sinks 23 absorb heat, which helps to expel the heat inside the cabinet 1 through the heat dissipation port 4 more quickly, thus improving the heat dissipation efficiency more effectively.

[0036] Working principle:

[0037] The timer switch 17 starts and stops the motor 16 and the vacuum cleaner 9 at set times. When the motor 16 is working, it can automatically drive the shaft tube 11, dust inlet tube 12, spring pressure rod 14 and cleaning brush 13 to rotate together. Therefore, when the cleaning brush 13 rotates, it will automatically sweep and clean the dust on the left side of the dust filter plate 5. When the shaft tube 11 rotates, it will drive the ball impact block 22 to rotate together. So the ball impact block 22 will continuously hit the semi-circular protrusion 21. During this process, the ball impact block 22 will continuously push the semi-circular protrusion 21 to the left through the arc surface. The semi-circular protrusion 21 will push the dust filter plate 5 to the left. At the same time, the dust filter plate 5 will compress the spring return rod 7. Combined with the elasticity of the spring return rod 7, the dust filter plate 5 can be driven to shake back and forth from left to right, and the dust on the dust filter plate 5 will be shaken off. Finally, after the vacuum cleaner 9 starts, it will absorb the cleaned dust through the dust cover 15.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
