Description

Technical Field

[0001] This utility model relates to the field of communication engineering technology, and in particular to a cabinet with a dust removal function. Background Technology

[0002] In communication engineering, cabinets are indispensable key equipment. They provide physical protection for communication equipment, resist external dust damage, and enable the orderly storage and centralized management of equipment for convenient maintenance. They can also adapt to different environments, ensure the stable operation of communication systems, and are an important support for ensuring the efficient and secure operation of communication networks.

[0003] However, current communication cabinets mostly use external air intake filtration for dust removal. This method has significant drawbacks. First, the filters are easily clogged by dust accumulation, requiring frequent cleaning and maintenance. This not only consumes a lot of manpower but may also disrupt the continuous operation of the communication system due to downtime. Second, during the dust removal process, some dust enters the equipment with the airflow, adhering to critical components such as circuit boards and interfaces, causing poor contact, short circuits, and other malfunctions, seriously threatening the normal operation of the equipment. In addition, these cabinets often cannot meet the cooling needs of the equipment while removing dust. When the equipment runs under high load for a long time, the heat is difficult to dissipate effectively, leading to a decline in equipment performance, a shortened lifespan, and greatly affecting the stability of the communication system.

[0004] In view of this, we have studied and improved the existing problems, and provided a cabinet with a dust removal function. The internal circulation design prevents external dust from entering, and the dynamic cooling system dissipates heat quickly through heat exchange to ensure cooling efficiency and stable operation of the equipment. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1 to 4A cabinet with a dust removal function includes a cabinet body 1, a cabinet door 2 movably connected to the front outer surface of the cabinet body 1, and a dust removal component 3 detachably connected to one side of the cabinet body 1.

[0025] The dust removal component 3 includes a control box 31. The rear end of the control box 31 is detachably connected to an air duct box 32. The upper end of the air duct box 32 is detachably connected to an upper arc-shaped air duct 33. The lower end of the air duct box 32 is detachably connected to an upper air duct 34. The rear end of the control box 31 is connected to the air duct box 32. The upper arc-shaped air duct 33 at the upper end of the air duct box 32 and the upper air duct 34 at the lower end cooperate to form an airflow channel under the drive of the control box. The air inside the cabinet is guided into the air duct box for treatment and then returned. Its detachable design facilitates maintenance, and the arc-shaped structure reduces wind resistance, improves dust removal efficiency and equipment adaptability.

[0026] A controller 37 is detachably connected to the middle of the control box 31, a cooling fan 38 is detachably connected to the upper middle of the control box 31, and a handle 39 is detachably connected to the lower middle of the control box 31. The controller 37 in the middle of the control box 31 regulates the overall operation, the cooling fan 38 at the upper end removes the high temperature from the back of the cooling chip, and the handle 39 at the lower end facilitates operation. The detachable design facilitates the inspection and replacement of components, improving the efficiency of equipment maintenance and ease of use.

[0027] Specifically, the upper arc-shaped air duct 34 is movably connected to the middle of the upper arc-shaped air duct 33, and the lower arc-shaped air duct 36 is movably connected to the middle of the lower arc-shaped air duct 35. The movable connection between the upper arc-shaped air duct 33 and the upper air duct 34, and between the lower arc-shaped air duct 35 and the lower air duct 36, can guide the airflow smoothly to help with dust removal and cooling. The movable connection design makes it easy to adjust the angle, adapt to different cabinet internal spaces, and improve the flexibility of use.

[0028] Specifically, an upper slot 311 is provided above the front end of the air duct box 32, and a lower slot 312 is provided below the front end of the air duct box 32. The middle front end of the air duct box 32 is detachably connected to the outer surfaces of the upper heat-conducting copper plate 313 and the lower heat-conducting copper plate 314 through the upper slot 311. The middle front end of the air duct box 32 is detachably connected to the outer surfaces of the filter box 310 through the lower slot 312. The upper slot 311 and the lower slot 312 at the front end of the air duct box 32 are used to detachably connect the upper heat-conducting copper plate 313, the lower heat-conducting copper plate 314 and the filter box 310, respectively. This achieves both circulating air cooling through the copper plates and dust removal through the filter box. The detachable design facilitates component replacement and maintenance, improving the practicality of the equipment.

[0029] Specifically, the outer surface of the rear end of the handle 39 is detachably connected to the outer surface of the front end of the filter box 310. The four sides of the rear end of the handle 39 are magnetically connected to the front end of the control box 31. The filter box 310 at the rear end of the handle 39 passes through the middle of the control box 31 and is detachably connected to the middle of the air duct box 32. The rear end of the handle 39 is connected to the filter box 310 and is connected to the control box 31 via magnetic attraction, which can drive the filter box through the control box and dock with the air duct box 32. This not only facilitates the disassembly and assembly of the filter box for cleaning and maintenance, but also provides a stable fixation and improves the ease of operation.

[0030] Specifically, the front outer surfaces of the upper heat-conducting copper plate 313 and the lower heat-conducting copper plate 314 are detachably connected to a cooling chip 315. A connector 316 is fixedly connected to the middle of the cooling chip 315. The front outer surface of the cooling chip 315 is detachably connected to the rear outer surface of the cooling fan 38. The front ends of the upper heat-conducting copper plate 313 and the lower heat-conducting copper plate 314 are connected to the cooling chip 315. The cooling chip is powered through the connector 316 and its front end is connected to the cooling fan 38. The cooling chip generates cold air, which is transferred to the circulating air for cooling through the copper plate. The cooling fan dissipates the heat from the cooling chip. The detachable design facilitates maintenance and improves cooling efficiency.

[0031] Specifically, the middle part of the cooling chip 315 is electrically connected to the upper middle part of the controller 37 via connector 316. The controller can regulate the operation of the cooling chip. This allows for on-demand adjustment of cooling efficiency to adapt to different cooling requirements. The connection is stable, easy to maintain, and improves the intelligence and reliability of the equipment.

[0032] Specifically, the upper outer surface of the air duct box 32 is detachably connected to one side of the upper part of the cabinet body 1 via the upper arc-shaped air duct 33. The upper part of the air duct box 32 is detachably connected to one side of the upper part of the cabinet body 1 via the upper arc-shaped air duct 33, which can guide the air inside the cabinet into the air duct box for processing. This connection not only ensures smooth airflow circulation, but also facilitates disassembly and maintenance, and enhances equipment adaptability.

[0033] Working principle: When the controller 37 receives a signal indicating excessive dust concentration from the dust sensor inside the cabinet, it immediately initiates the dust removal program. At this time, the cooling fan 38 is powered on and its blades rotate at high speed to create a negative pressure zone. A complete air circulation path is constructed through the upper arc-shaped air duct 33 and upper air duct 34 at the top of the air duct box 32, and the lower arc-shaped air duct 35 and lower air duct 36 at the bottom. The curved surface design of the upper arc-shaped air duct 33 and lower arc-shaped air duct 35 reduces airflow resistance, allowing the dust-laden air inside the cabinet body 1 to be more smoothly drawn into the air duct box 32. After entering the air duct box 32, the air first flows through the filter box 310 at the lower slot 312. The multi-layered filters inside the filter box 310, such as the pre-filter, intercept large dust particles, and the high-efficiency filter, capture fine dust. Through physical barrier and adsorption, the dust is trapped. The purified air is pushed by the cooling fan 38 and flows back to the main body of the cabinet 1 through the upper air duct 34 and the lower air duct 36, forming a closed-loop dust removal cycle. At the same time, the magnetic connection structure between the handle 39 and the control box 31 allows the operator to quickly disassemble the filter box 310 for cleaning or replacement without tools. This design avoids the excessive downtime caused by complex filter removal in traditional cabinets, and the internal circulation design eliminates the risk of external dust entering the equipment through the airflow. The upper and lower heat-conducting copper plates 313 and 314 are embedded inside the air duct box 32 through the upper slot 311, their smooth surfaces forming a large contact area with the circulating air. When the controller 37 detects that the internal temperature of the cabinet exceeds a preset threshold, it supplies current to the cooling element 315 through the connector 316. The cooling element 315 is based on the Peltier effect. The cold end is rapidly cooled and the cold energy is diffused through the tightly fitted upper heat-conducting copper plate 313 and lower heat-conducting copper plate 314, making the surface temperature of the copper plate significantly lower than the temperature of the circulating air. When the circulating air flows in the air duct box 32, it exchanges heat with the low-temperature copper plate. The heat in the air is absorbed by the copper plate, and the cooled circulating air re-enters the main body of the cabinet 1, carrying away the heat generated by the equipment operation, thus achieving dynamic cooling. Meanwhile, the heat generated by the hot end of the cooling chip 315 is quickly dissipated to the outside of the control box 31 through the forced air cooling effect of the cooling fan 38, ensuring stable cooling efficiency.
