The communication cabinet is made of metal or non-metallic materials, does not allow unauthorized operators to enter the cabinet, and provides outdoor physical working environment and security system equipment for wireless communication sites or wired network site workstations.

Temperature is one of the important factors for the long-term reliable operation of the communication cabinet. The single board of the communication cabinet is highly integrated and uses many large-scale chips. These chips will generate a lot of heat during operation. If the cooling effect of the cabinet is not good, the temperature will rise. If the temperature is high, it will affect the normal operation of the board, which may cause code errors and signal interruptions in the branch or optical path. Some temperature-sensitive chips or boards will be damaged or leave Hidden dangers will affect its long-term use.

In the prior art, the communication cabinet generally adopts air cooling and water cooling to dissipate the heat of the cabinet, but this cooling method will not improve the cooling effect in a targeted manner when the temperature of the cabinet is too high, so that the cabinet cannot work in real time according to the chip. The temperature adjusts the heat dissipation effect, and the air cooling is generally carried out by the cooling fan, but the static electricity generated by the rotating friction of the fan after long-term operation will cause a large amount of dust to adhere to the surface of the fan blade, which will affect the normal operation of the fan blade, resulting in Decrease in cooling effect.

Working principle, the communication cabinet generally adopts air cooling and water cooling to dissipate the heat of the cabinet, but this cooling method will not improve the cooling effect in a targeted manner when the temperature of the cabinet is too high, so that the cabinet cannot be controlled according to the real-time working temperature of the chip. The heat dissipation effect is adjusted, and the air cooling is generally carried out by the heat dissipation fan, but after a long-term operation of the fan, the static electricity generated by the rotating friction will cause a large amount of dust to adhere to the surface of the fan blade, which will affect the normal operation of the fan blade and cause the heat dissipation effect The cooling water in the cooling pipe in the communication cabinet 1 enters the heat dissipation pipe 7 on the heat dissipation plate 6 through the water inlet pipe 5 after being circulated and cooled for a circle, and then enters the water delivery pipe 8 from the heat dissipation pipe 7 after multiple cycles, and passes through After the water pump 9 is extracted, it enters the cooling pipe again through the water outlet pipe 10 to water-cool the communication cabinet 1, because the heat dissipation plate 6 is filled with heat-conducting materials, so that the heat dissipation plate 6 can quickly export the heat in the cooling water, which is measured in real time by the temperature sensor 3 The working temperature in the communication cabinet 1, when the temperature in the communication cabinet 1 is too high, start the servo motor 15 on one side of the cooling plate 6, and drive the rotating shaft 16 to rotate through the servo motor 15, so that the cooling fan blade 17 blows the cooling plate 6 Quickly take away the heat on the cooling plate 6, thereby avoiding that the heat accumulation on the cooling plate 6 cannot be quickly dissipated, and improving the heat conduction effect of the cooling plate 6. 18, so that the wind blown out by the heat dissipation fan blade 17 can be accumulated to achieve the effect of deriving the heat on the heat dissipation plate 6 faster, and the temperature sensor 3 cooperates with the heat dissipation plate 6, the heat dissipation fan blade 17 and the wind cover 18 can be in the communication cabinet 1 When the temperature in the communication cabinet 1 is too high, the heat conduction to the cooling water is accelerated, thereby realizing the rapid adjustment of the temperature in the communication cabinet 1, and avoiding that the temperature in the communication cabinet 1 is too high to affect the normal use and working life of the electrical components. When the temperature in the communication cabinet 1 is still too high after the servo motor 15 on the side works, the valves on the water inlet pipe 11 and the water outlet pipe 14 are all opened, and the valve on the water delivery pipe 8 is closed. The cooling water enters the annular pipe 12 in the air cylinder 22 through the water inlet pipe 11, and enters the heat pipe 23 through the inclined pipe 13, and finally enters the water delivery pipe 8 from the heat pipe 23.

Furthermore, the two antifouling covers 28 slide relatively and form a cover body to protect the heat dissipation fan blade 17, which can prevent the cleaning liquid and dust impurities thrown out due to the rotation action from being scattered in the heat dissipation box 2 during the cleaning process, thereby ensuring heat dissipation. The inner cavity of the tank 2 is clean. When the valve in the liquid outlet pipe 45 is opened, the cleaning liquid enters the semi-circular nozzle 46 and sprays out from the nozzles 47 on both sides. Through the design of the semi-circular nozzle 46 and the nozzle 47 , so that the cleaning liquid can be more fully in contact with both sides of the cooling fan blade 17, which improves the effect of removing dust and impurities. The electromagnet 29 on the side is energized, so that the two semi-annular fixing parts 30 are relatively slid to form a ring body under the drive of the permanent magnet 27. At this time, the two semi-annular ratchets 31 are also integrated into a whole and meshed with the pawl 33. , the servo motor 15 starts, and the rotating shaft 16 drives the ratchet 33 to rotate, so that the two half-ring ratchets 31 start to rotate under the action of the ratchet 33, and the pole 34 and the brush plate 35 rotate thereupon to remove dust and impurities on the filter plate 4.
