Description

Technical Field

[0001] This utility model relates to the field of communication base station technology, and in particular to a heat dissipation device for communication base stations. Background Technology

[0002] As the core infrastructure of modern mobile communication networks, communication base stations undertake the critical tasks of signal coverage and data transmission. Their internal main equipment, radio frequency units, and power modules generate a significant amount of heat during continuous operation. To ensure stable operation of base station equipment at suitable temperatures and prevent performance degradation, equipment aging, or even system failure due to overheating, efficient and reliable heat dissipation devices have become an indispensable and crucial component of communication base stations.

[0003] Currently, traditional heat dissipation methods commonly used in communication base stations, such as natural ventilation, forced air cooling, or air conditioning, have many limitations in practical applications. Natural ventilation has low heat dissipation efficiency and is difficult to meet the heat dissipation needs of high-power equipment; forced air cooling can improve efficiency, but it is prone to drawing in dust and lint during long-term operation, causing dust filters and heat dissipation fins to become clogged, resulting in a sharp decline in heat dissipation efficiency, and requiring frequent manual cleaning and maintenance; while air conditioning has the problems of excessive energy consumption, complex structure, and high cost.

[0004] Therefore, it is necessary to design a heat dissipation device for communication base stations to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the obvious limitations of traditional heat dissipation methods commonly used in current communication base stations, such as natural ventilation, fan cooling, or air conditioning, natural ventilation is inefficient and cannot meet the high power heat dissipation requirements; fan cooling is prone to dust accumulation and blockage, requiring frequent maintenance; and air conditioning has the disadvantages of high energy consumption, complex structure, and high cost, this utility model provides a heat dissipation device for communication base stations.

[0006] Technical Solution: A heat dissipation device for a communication base station includes a fixed frame, a heat dissipation frame, a heat-conducting copper plate, fins, mounting cylinders, a fixed shell, bearings, a rotating shaft, arc-shaped magnets, magnetic blocks, and heat dissipation fan blades. The fixed frame has symmetrical mounting holes on both sides of its rear. The heat dissipation frame is fixedly connected to the front of the fixed frame. A heat-conducting copper plate is fixedly connected inside the heat dissipation frame. Multiple fins are fixedly connected in a linear array to the front of the heat-conducting copper plate. Mounting cylinders are fixedly connected to both sides of the front of the heat dissipation frame, forming a sealed cavity with the heat dissipation frame. A fixed shell is fixedly connected inside each of the two mounting cylinders. Bearings are rotatably connected inside each of the two fixed shells. A rotating shaft is fixedly connected to the inner ring of each of the two bearings. Multiple arc-shaped magnets are fixedly connected to the outside of each of the two rotating shafts. Magnetic blocks are symmetrically embedded and fixedly connected inside the two fixed shells. Heat dissipation fan blades are fixedly connected to the rear of each of the two rotating shafts, penetrating into the sealed cavity.

[0007] Furthermore, it is particularly preferred that both cooling fan blades are located in front of multiple fins.

[0008] Furthermore, it is particularly preferred that the device also includes a dustproof net, a connecting shaft, and a cleaning brush. The dustproof net is fixedly connected to the rear of both fixed housings, and the connecting shaft is fixedly connected to the rear of both rotating shafts. The cleaning brush is fixedly connected to the rear of both connecting shafts through the dustproof net, and both cleaning brushes abut against the corresponding dustproof nets.

[0009] In addition, it is particularly preferred that the device also includes a rain shield, which is fixedly connected to the front of the heat dissipation frame and is located in front of the two dustproof nets.

[0010] In addition, it is particularly preferred that multiple exhaust ports are provided on both the left and right sides of the heat dissipation frame.

[0011] In addition, it is particularly preferred that a sealing sleeve is included, with a sealing sleeve fixedly connected inside each vent.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model utilizes the constant magnetic field generated by the magnetic block to interact periodically with the rotating arc magnet, forming an auxiliary driving effect. This significantly reduces the rotational resistance of the shaft, enabling the cooling fan blades to operate at high speed with lower energy consumption. The resulting strong airflow directly acts on the fin group, quickly carrying away the heat transferred by the heat-conducting copper plate. Compared with natural ventilation and high-power air conditioning, this achieves an optimized balance between heat dissipation efficiency and energy consumption control.

[0013] 2. When the rotating shaft rotates under magnetic drive, it simultaneously drives the connecting shaft and the cleaning brush to rotate. The cleaning brush continuously abuts against and rotates to scrape the rear side of the dustproof net, which can automatically remove the dust and lint attached to the net surface, ensuring that the dustproof net remains unobstructed for a long time. This avoids the decrease in airflow and heat dissipation failure caused by the blockage of the dustproof net, and significantly reduces the frequency and cost of daily maintenance.

[0014] 3. This utility model uses a rain shield located in front of the dustproof net to effectively block rainwater from directly washing away the dust without affecting normal air intake; while the sealing sleeve installed in the exhaust port is sealed and waterproof when static, and can be smoothly opened by the airflow when dynamically exhausting, thus realizing passive opening and closing management of the heat dissipation channel.

[0022] A heat dissipation device for a communication base station, such as Figures 1-6 As shown, it includes a fixed frame 1, a heat dissipation frame 3, a heat-conducting copper plate 4, fins 5, a mounting cylinder 6, a fixed shell 7, a bearing 11, a rotating shaft 8, an arc-shaped magnet 9, a magnetic block 10, and heat dissipation fan blades 12. The fixed frame 1 has symmetrical mounting holes 2 on both the left and right sides at the rear. The heat dissipation frame 3 is mounted on the front side of the fixed frame 1 with screws. The heat dissipation frame 3 has four exhaust ports on both the left and right sides. A heat-conducting copper plate 4 is mounted on the rear side of the heat dissipation frame 3 with screws. Multiple fins 5 are mounted in a linear array on the front side of the heat dissipation frame 3. The heat dissipation frame 3 has four exhaust ports on both the left and right sides. Mounting cylinders 6 are welded on both sides. The two mounting cylinders 6 and the heat dissipation frame 3 form a sealed cavity. Fixing shells 7 are welded inside the two mounting cylinders 6. Bearings 11 are rotatably connected inside the two fixing shells 7. The inner rings of the two bearings 11 are fixedly connected to the rotating shafts 8. Multiple arc-shaped magnets 9 are glued to the outer side of the two rotating shafts 8. Magnetic blocks 10 are symmetrically embedded in the two fixing shells 7 and glued to them. Heat dissipation fan blades 12 are welded into the sealed cavity at the rear end of the two rotating shafts 8. The two heat dissipation fan blades 12 are located in front of the multiple fins 5.

[0023] like Figure 1 , Figure 4 and Figure 6As shown, it also includes a dustproof mesh 13, a connecting shaft 14, a cleaning brush 15, a rain shield 16, and a sealing sleeve 17. Dustproof mesh 13 is installed on the rear side of both fixed shells 7 by screws. Connecting shafts 14 are welded to the rear ends of both rotating shafts 8. The rear ends of both connecting shafts 14 extend out of the dustproof mesh 13 and are fixedly connected to the cleaning brush 15. Both cleaning brushes 15 abut against the corresponding dustproof mesh 13. A rain shield 16 is installed on the upper front side of the heat dissipation frame 3 by screws. The rain shield 16 is located in front of the two dustproof meshes 13. A sealing sleeve 17 is fixedly connected inside each exhaust port.

[0024] When this device is needed to dissipate heat from a communication base station, it is first fixedly installed on the outer casing or designated location of the heat-generating equipment of the base station through the mounting holes 2 at the rear of the fixing frame 1, ensuring that the heat-conducting copper plate 4 is in close contact with the heat-generating components. When the base station equipment starts operating and generates heat, the heat is rapidly conducted to the heat-conducting copper plate 4 and further diffused onto the multiple fins 5, thereby greatly increasing the contact area with the air and laying the foundation for efficient heat dissipation. At this time, the magnetic block 10 generates a constant magnetic field. When the initial drive shaft 8 starts to rotate, the multiple arc-shaped magnets 9 will rotate accordingly. Due to the interaction between the magnetic poles, the arc-shaped magnets 9 will be subjected to periodic pushing and pulling forces when passing through the constant magnetic field generated by the magnetic block 10. This magnetic driving effect... This should significantly reduce the rotational resistance of the shaft 8 and assist it in accelerating rotation, thereby achieving efficient and low-energy operation. Driven by the shaft 8, the two cooling fan blades 12 begin to rotate synchronously, generating a powerful directional airflow. The high-speed airflow generated by the rotation of the cooling fan blades 12 blows directly onto multiple fins 5. The airflow quickly carries away the heat accumulated on the surface of the fins 5 and exhausts the hot air to the outside of the device through four exhaust ports. At the same time, the cooler air outside the device is continuously replenished into the sealed cavity, forming a continuous and effective cooling cycle. The sealing sleeve 17 can effectively prevent external dust and moisture from entering when stationary, while during exhaust, the airflow can smoothly open the sealing sleeve 17 to exhaust the heat, achieving a unity of heat dissipation and sealing protection.

[0025] To further improve the long-term operational stability of the device, the dustproof net 13 is used to block most of the dust and lint in the air from entering the sealed cavity and the interior of the heat dissipation frame 3. At the same time, when the rotating shaft 8 rotates, it will drive the connecting shaft 14 and the cleaning brush 15 to rotate together. The cleaning brush 15, which is always in contact with the rear side of the dustproof net 13, will continuously scrape off the dust attached to the outer surface of the dustproof net 13 during the rotation process, thereby realizing the self-cleaning of the dustproof net 13 and avoiding the impact of dust accumulation on the ventilation and heat dissipation effect. In addition, the rain shield 16 can effectively block rainwater from directly washing the dustproof net 13 without affecting the normal air intake.
