Description

Technical Field

[0001] The present invention relates to the technical field of communication cabinets, and in particular to an air cooling system and a communication cabinet thereof. Background Art

[0002] The equipment inside a communications cabinet generates a large amount of heat during operation. If heat is not dissipated in a timely manner, the equipment will overheat, affecting normal operation or even damaging the equipment. Poor heat dissipation may also lead to reduced equipment efficiency, increased energy consumption, shortened equipment life, and may cause safety accidents such as fire. Therefore, heat dissipation in communications cabinets is very necessary.

[0003] Traditional axial fan direct-blowing cooling systems use a single direction of air delivery and lack a structured air duct design. This creates turbulent airflow within the cabinet, leading to severe mixing of hot and cold air. This prevents the cold air from accurately reaching all heat sources, making it difficult to eliminate local hot spots and causing uneven equipment operating temperatures. Therefore, an air-cooling system and its associated communications cabinet are proposed to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and propose an air cooling system and its communication cabinet to solve the problem that the traditional axial flow fan direct blowing heat dissipation system in the above technical solution adopts a single direction of air supply and lacks a structured air duct design, which leads to turbulent air flow in the cabinet, mixing of hot and cold air, inaccurate cold air coverage, easy generation of local hot spots and uneven equipment temperature.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: an air cooling system, comprising an air duct assembly, a flow guide assembly provided on the air duct assembly, and a mounting assembly provided on the air duct assembly; The air duct assembly includes a first centrifugal fan, a mounting cover is installed above the first centrifugal fan, a second centrifugal fan is installed in the mounting cover, a first partition is installed above the first centrifugal fan, a top of the first partition is fixedly connected to a base, a top of the base is clamped to a clamping rod, and the top of the clamping rod is fixedly connected to the second partition.

[0007] The beneficial effect of adopting the above-mentioned further scheme is: by setting up a multi-level air duct system to optimize the air flow path, the first air duct of the first partition is directly connected to the first centrifugal fan to ensure uniform air intake at the bottom, and the second partition adopts a three-dimensional layout of the first strip through hole + the second air duct, the second strip through hole + the third air duct to achieve stratified flow of cold and hot air and avoid circulating mixed flow.

The filter design is added on the basis of the multi-stage air duct system, which not only increases the wind pressure but also realizes two-stage filtration, effectively preventing dust from entering the cabinet.

[0013] The beneficial effect of adopting the above further scheme is that the guide plate and the second partition plate form an acute angle, which can enhance the guiding effect and guide the airflow to the target area more accurately.

[0020] Compared with the prior art, the advantages and positive effects of the present application are that: Firstly, the first centrifugal fan of the present application draws external cold air into the first air duct in the first partition plate, the cold air enters the second air duct in the second partition plate connected with the first partition plate, and then is discharged into the cabinet through the first slot-shaped hole, the equipment in the cabinet is air-cooled and cooled, then the hot air with the heat of the equipment enters the third air duct in the second partition plate through the second slot-shaped hole, and is discharged through the fourth air duct and the second centrifugal fan, which avoids the airflow organization disorder of the traditional axial flow fan direct blowing type heat dissipation and the easy mixing of cold and hot airflows.

[0021] Secondly, the damper shaft can conveniently adjust the inclination angle of the flow guide plate under the action of the damper shaft, and since the flow guide plate is between the first slot-shaped hole and the second slot-shaped hole, the cold air discharged from the first slot-shaped hole can be guided to the equipment in the cabinet, the airflow is uniformly covered on the surface of the equipment, and the air-cooling efficiency is improved.

[0022] Third, the present invention inserts the card rod into the card seat, and the first partition and the second partition can be assembled together, and then the first magnetic strip and the second magnetic strip are magnetically installed. At the same time, the third magnetic strip and the fourth magnetic strip are magnetically installed, and the first partition and the second partition can be quickly installed on both sides of the cabinet.

[0028] The first air duct forms a three-dimensional airflow path with the second and third air ducts, physically isolating the hot and cold air to avoid confusion. The distribution of the strip through-holes matches the equipment layout to ensure that the cold air accurately covers the key heat sources.

[0029] The first partition 104 and the second partition 105 are both made of high-strength aluminum alloy. The spiral first air duct, the second air duct and the third air duct are precisely milled by a CNC machining center, and the surface is hard anodized to improve wear resistance and thermal conductivity.

[0030] The air outlet of the first centrifugal fan 101 is connected to the first air duct in the first partition 104, and a fourth air duct connected to the third air duct is opened at the bottom of the installation cover 102. The air inlet of the first centrifugal fan 101 and the air outlet of the second centrifugal fan 103 are both provided with filters.

[0031] The first centrifugal fan 101 is of CF-101H model, with a rated air volume of 1200m³ / h and a static pressure of 120Pa. The air outlet end of the first centrifugal fan 101 is connected with the first air duct inlet flange through a flexible bellows.

[0033] The socket 201 is fixed to the right side of the second partition plate 105 and has an elastic buckle made of spring steel with an elastic coefficient of 1200N / mm, ensuring stable connection of the plug block 202. The plug block 202 is made of flame-retardant PC material and has a matte surface treatment to enhance friction. The damping shaft 203 is internally provided with a high-precision bearing of model 6200ZZ and precision grade P4, with a friction coefficient adjustable range of 0.1-0.5N·m, achieving stepless adjustment of the flow guide plate 204. The flow guide plate 204 is made of an aluminum alloy sheet with a thickness of 1.5mm, a high-temperature resistant coating on the surface, and a temperature resistance of 200℃. The inclination angle can be freely adjusted within a range of 0° to 45°. After the flow guide plate 204 is rotated to a specified angle through the damping shaft 203, the cold air is divided at the first slot-shaped hole. Part of the airflow is vertically downward along the second air duct, and part of the airflow is guided to the heating area of the equipment through the flow guide plate 204. The hot air enters the third air duct through the second slot-shaped hole and is finally discharged from the cabinet 4 by the second centrifugal fan 103 under the communication of the fourth air duct.

[0034] The socket 201 is fixedly connected to the second partition plate 105 and is located between the first slot-shaped hole and the second slot-shaped hole. The flow guide plate 204 is designed to incline away from the second partition plate 105.

[0035] In another aspect, the application also provides a communication cabinet, comprising a cabinet body 4, a first magnetic strip 301 embeddedly installed on a first partition plate 104, a second magnetic strip 302 embeddedly installed on the cabinet body 4 and magnetically attracted to the first magnetic strip 301, a third magnetic strip 303 embeddedly installed on a second partition plate 105, and a fourth magnetic strip 304 embeddedly installed on the cabinet body 4 and magnetically attracted to the third magnetic strip 303.

[0036] The first centrifugal fan 101 is bolted to the bottom of the cabinet body 4, and a first shock pad is arranged between the first centrifugal fan 101 and the cabinet body 4; the mounting cover 102 is fixedly connected to the top of the cabinet body 4; the second centrifugal fan 103 is bolted to the top of the cabinet body 4, and a second shock pad is arranged between the second centrifugal fan 103 and the cabinet body 4.

[0037] The first centrifugal fan 101 is bolted to the bottom of the cabinet body 4 by M6 bolts, and the first shock pad is made of ethylene-propylene-diene rubber with a hardness of 50 Shore A; the second centrifugal fan 103 is bolted to the top of the cabinet body 4 by M8 bolts, and the second shock pad is made of silica gel with a hardness of 40 Shore A.

[0038] The first partition plate 104 is two in number and is installed on the left and right sides of the cabinet body 4 respectively; the second partition plate 105 is two in number and is installed on the left and right sides of the cabinet body 4 respectively.

[0039] Working principle: First, according to the specific assembly situation of the equipment in the cabinet 4, adjust the angle of the guide plate 204 by rotating the damping shaft 203, and then insert the plug block 202 into the socket 201 to fix the guide plate 204 on the surface of the second partition 105, and then insert the card rod 107 into the card seat 106 to complete the assembly of the first partition 104 and the second partition 105, and then magnetically install the first magnetic strip 301 and the second magnetic strip 302. At the same time, magnetically install the third magnetic strip 303 and the fourth magnetic strip 304, which can achieve rapid installation of the first partition 104 and the second partition 105. When the equipment in the cabinet 4 is running, start the first centrifugal fan 101 and the second centrifugal fan 103. The first centrifugal fan 101 draws the outside cold air into the first air duct in the first partition 104, and the cold air enters the second air duct in the second partition 105 connected to the first partition 104, and then is discharged into the cabinet 4 through the first bar-shaped through hole. , under the guiding effect of the guide plate 204, the cold air can optimize the airflow direction according to the position of different heat sources, evenly cover the cold air on the surface of the equipment, and cool the equipment in the cabinet 4. Subsequently, the hot air carrying the heat of the equipment enters the third air duct in the second partition 105 from the second bar-shaped through hole, and is discharged through the fourth air duct and the second centrifugal fan 103, avoiding the chaotic airflow organization of the traditional axial flow fan direct blowing heat dissipation, and the hot and cold air flows are easy to mix. When the first partition 104 or the second partition 105 fails and needs maintenance, the first partition 104 and the second partition 105 are pulled to both sides until the first magnetic strip 301 is separated from the second magnetic strip 302, and the third magnetic strip 303 is separated from the fourth magnetic strip 304, so that the first partition 104 and the second partition 105 can be quickly disassembled, and then the card rod 107 is pulled out from the card seat 106 to separate the first partition 104 from the second partition 105 for easy maintenance.
