Description

Technical Field

[0001] This utility model relates to the field of communication base station technology, and in particular to a cooling structure for a 5G communication base station. Background Technology

[0002] Because 5G communication base stations have a much higher power density than 4G base stations, their core components generate a lot of heat during operation. If the heat accumulates and cannot be dissipated in time, it can easily cause equipment failure, signal delay, or even shorten the service life. Therefore, a reliable cooling solution is the key to ensuring its continuous operation.

[0003] However, in existing technologies, although the antenna unit of a distributed base station adopts a Y-shaped fin structure to increase the heat dissipation area, when the ambient temperature is too high, the heat dissipation effect of natural convection is highly dependent on the temperature difference between the ambient temperature and the heat dissipation component. When the ambient temperature rises, the temperature difference between the two decreases, and the driving force for heat transfer from the fins to the surrounding air weakens. Even if the Y-shaped fins increase the heat dissipation contact area, it is difficult to compensate for the lack of heat dissipation power caused by insufficient temperature difference. This will cause the chip temperature to exceed the design target, which will directly affect the processing capability of the antenna unit, resulting in decreased signal stability, signal attenuation, transmission delay or increased interference, and thus affect the communication quality in the base station coverage area, such as user call interruption and reduced data transmission rate. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a cooling structure for 5G communication base stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes an antenna unit, with heat dissipation fins fixedly connected to the back of the antenna unit. A moving mechanism is fixedly connected to the side of the heat dissipation fins. A heat dissipation mechanism is mounted on the surface of the moving mechanism. The moving mechanism includes two slide rails, which are symmetrically fixedly connected to both sides of the heat dissipation fins. A slider is slidably connected inside each slide rail. A servo motor is fixedly connected to the end of one slide rail. A lead screw is fixedly connected to the output end of the servo motor. The lead screw is threadedly connected to the slider. A mounting bracket is fixedly connected to the surface of the slider. The heat dissipation mechanism includes a fan, with protective covers fixedly connected to both sides of the fan. The mounting bracket is fixedly connected to the side of the fan.

[0006] Preferably, a wiping mechanism is fixedly connected to the bottom of the fan. The wiping mechanism includes a mounting frame, which is fixedly connected to the bottom of the fan. A wiping strip is fixedly connected to the end of the mounting frame, and the wiping strip is in contact with the surface of the heat dissipation fins.

[0007] Preferably, the protective cover has multiple ventilation holes on its surface, and the multiple ventilation holes are evenly distributed on the surface of the protective cover.

[0008] Preferably, a scraping mechanism is fixedly connected to the surface of the slide rail. The scraping mechanism includes a telescopic component, a fixed block is fixedly connected to the end of the telescopic component, and a scraper is fixedly connected to the side of the fixed block.

[0009] Preferably, the telescopic assembly includes a telescopic rod and a spring. One end of the telescopic rod is fixedly connected to the slide rail, and the other end of the telescopic rod is fixedly connected to the fixing block. One end of the spring is fixedly connected to the slide rail, and the other end of the spring is fixedly connected to the fixing block.

[0010] Preferably, the scraping mechanism further includes a guide plate, which is fixedly connected to the upper part of the protective cover on the air inlet side of the fan, and the upper part of the guide plate is provided with an arc-shaped chamfer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the heat dissipation fins on the back of the antenna unit continue the basic heat dissipation function. However, through the synergistic effect of the moving mechanism and the heat dissipation mechanism, the efficiency bottleneck of natural convection in high-temperature environments is effectively overcome. The fan in the heat dissipation mechanism can enhance airflow through active ventilation to compensate for the lack of heat dissipation power caused by the rise in ambient temperature. The protective covers on both sides can protect the fan from external impurities to maintain stable operation. At the same time, the slide rail of the moving mechanism provides sliding guidance for the slider. The servo motor drives the lead screw to rotate, which drives the slider and the fan connected to the surface fixing frame to precisely adjust the position, so as to achieve full coverage heat dissipation of each area of ​​the heat dissipation fins, avoid local heat accumulation, and thus ensure that the chip of the antenna unit is always within a safe temperature range, reduce signal attenuation and transmission delay, improve the communication quality of the base station coverage area, and the overall structure is suitable for the application scenario of distributed base stations, taking into account both heat dissipation efficiency and operational stability. 2. In this utility model, when the moving mechanism drives the fan to move along the slide rail, the mounting bracket fixed to the bottom of the fan in the wiping mechanism will synchronously drive the wiping strip to move, and the wiping strip will be in contact with the surface of the heat dissipation fins, so as to wipe the dust on the surface of the heat dissipation fins in real time, avoid the accumulation of dust to hinder the heat transfer of the heat dissipation fins, and ensure its basic heat dissipation capacity. 3. In this invention, the fan drives the guide plate fixed to the upper part of the air intake side protective cover to move. The arc-shaped chamfer of the guide plate can smoothly push the scraper of the scraping mechanism, causing the scraper to retract through the fixed block and compress the spring. The spring's rebound force allows the scraper to fit tightly against the surface of the protective cover, thus simultaneously scraping away dust from the surface of the air intake side protective cover during the fan's movement, preventing the ventilation holes from becoming blocked and affecting the fan's air intake efficiency. Through dual dust removal of the heat dissipation fins and the protective cover, the fan continuously ensures efficient ventilation and heat dissipation for the heat dissipation fins.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a cooling structure for a 5G communication base station, including an antenna unit 1. A heat dissipation fin 2 is fixedly connected to the back of the antenna unit 1. A moving mechanism 3 is fixedly connected to the side of the heat dissipation fin 2. A heat dissipation mechanism 4 is installed on the surface of the moving mechanism 3. The moving mechanism 3 includes two slide rails 31, which are symmetrically fixedly connected to both sides of the heat dissipation fin 2. A slider 32 is slidably connected inside the slide rail 31. A servo motor 33 is fixedly connected to the end of one slide rail 31. A lead screw 34 is fixedly connected to the output end of the servo motor 33. The lead screw 34 is threadedly connected to the slider 32. A fixing frame 35 is fixedly connected to the surface of the slider 32. The heat dissipation mechanism 4 includes a fan 41. Protective covers 42 are fixedly connected to both sides of the fan 41. The fixing frame 35 is fixedly connected to the side of the fan 41.

[0017] The specific settings and functions of this embodiment are described below: When the antenna unit 1 is working in a high-temperature environment, if the heat dissipation fins 2 cannot meet the heat dissipation requirements, the fan 41 is used to ventilate and dissipate heat from the heat dissipation fins 2, thereby improving the heat dissipation efficiency of the heat dissipation fins 2 for the antenna unit 1. At the same time, the servo motor 33 drives the lead screw 34 to rotate, thereby driving the slider 32 to slide along the slide rail 31, thereby adjusting the position of the fan 41. By adjusting the position of the fan 41, it can fully dissipate heat from all positions of the heat dissipation fins 2. The heat sink fins 2 on the back of the antenna unit 1 continue the basic heat dissipation function. Through the synergistic action of the moving mechanism 3 and the heat dissipation mechanism 4, the efficiency bottleneck of natural convection in high-temperature environments is effectively overcome. The fan 41 in the heat dissipation mechanism 4 can enhance airflow through active ventilation to compensate for the lack of heat dissipation power caused by the rise in ambient temperature. The protective covers 42 on both sides can protect the fan 41 from external impurities to maintain stable operation. At the same time, the slide rail 31 of the moving mechanism 3 provides sliding guidance for the slider 32. The servo motor 33 drives the lead screw 34 to rotate, which drives the slider 32 and the fan 41 connected to the surface fixing bracket 35 to precisely adjust the position, so as to achieve full coverage heat dissipation of each area of ​​the heat sink fins 2, avoid local heat accumulation, and thus ensure that the chip of the antenna unit 1 is always within a safe temperature range, reduce signal attenuation, transmission delay and other problems, improve the communication quality of the base station coverage area, and the overall structure is suitable for the application scenario of distributed base stations, taking into account both heat dissipation efficiency and operational stability.

[0018] Example 2: Figure 2 - Figure 5 As shown, a wiping mechanism 6 is fixedly connected to the bottom of the fan 41. The wiping mechanism 6 includes a mounting bracket 61, which is fixedly connected to the bottom of the fan 41. A wiping strip 62 is fixedly connected to the end of the mounting bracket 61. The wiping strip 62 is in contact with the surface of the heat dissipation fins 2. Multiple ventilation holes are provided on the surface of the protective cover 42, and the ventilation holes are evenly distributed on the surface of the protective cover 42. A scraping mechanism 5 is fixedly connected to the surface of the slide rail 31. The scraping mechanism 5 includes a telescopic component, and a fixing block 5 is fixedly connected to the end of the telescopic component. 3. A scraper 54 is fixedly connected to the side of the fixed block 53. The telescopic assembly includes a telescopic rod 51 and a spring 52. One end of the telescopic rod 51 is fixedly connected to the slide rail 31, and the other end of the telescopic rod 51 is fixedly connected to the fixed block 53. One end of the spring 52 is fixedly connected to the slide rail 31, and the other end of the spring 52 is fixedly connected to the fixed block 53. The scraping mechanism 5 also includes a guide plate 55. The guide plate 55 is fixedly connected to the upper part of the protective cover 42 on the air inlet side of the fan 41, and the upper part of the guide plate 55 is provided with an arc-shaped chamfer.

[0019] The overall effect of this embodiment is that, during the process of the fan 41 dissipating heat from the heat dissipation fins 2, the fan 41 is protected by the protective cover 42. During the process of the moving mechanism 3 driving the fan 41 to move in position, the mounting bracket 61 drives the wiping strip 62 to move with the fan 41. The wiping strip 62 wipes the surface of the heat dissipation fins 2, preventing the surface of the heat dissipation fins 2 from being covered by dust. During the movement of the fan 41, the fan 41 will also drive the guide plate 55 to move. The arc-shaped chamfer of the guide plate 55 causes the scraper 54 to push the telescopic rod 51 and the spring 52 to compress. Then the scraper 54 will stick to the surface of the protective cover 42. Through the elasticity of the telescopic rod 51 and the spring 52, the scraper 54 will stick to the surface of the protective cover 42, and the dust on the surface of the protective cover 42 on the air intake side of the fan 41 will be scraped off, ensuring the ventilation and heat dissipation performance of the fan 41 for the heat dissipation fins 2. The protective cover 42 provides physical protection for the fan 41, while its evenly distributed ventilation holes ensure normal air intake, providing a basic condition for heat dissipation. When the moving mechanism 3 moves the fan 41 along the slide rail 31, the mounting bracket 61 fixed to the bottom of the fan 41 in the wiping mechanism 6 simultaneously moves the wiping strip 62. The wiping strip 62 adheres to the surface of the heat dissipation fins 2, wiping away dust in real time, preventing dust accumulation from hindering heat transfer and ensuring basic heat dissipation capacity. Simultaneously, the fan 41 moves the guide plate 55 fixed to the upper part of the air intake protective cover 42. The rounded chamfer of the guide plate 55 smoothly pushes the scraper 54 of the scraping mechanism 5, allowing the scraper 54 to... 4. The telescopic rod 51 retracts and the spring 52 is compressed by the fixed block 53. The rebound force of the spring 52 allows the scraper 54 to fit tightly against the surface of the protective cover 42, thereby scraping away the dust on the surface of the protective cover 42 on the air intake side during the movement of the fan 41, preventing the ventilation holes from being blocked and affecting the air intake efficiency of the fan 41. Finally, through the dual dust removal of the heat dissipation fins 2 and the protective cover 42, the efficient ventilation and heat dissipation effect of the fan 41 on the heat dissipation fins 2 is continuously ensured, ensuring that the temperature of the antenna unit 1 chip is stable within the design target, effectively avoiding problems such as signal attenuation and transmission delay, improving the communication quality of the base station coverage area, and each dust removal mechanism works in conjunction with the movement of the fan 41 without the need for additional power, taking into account both practicality and energy saving.

[0020] The usage and working principle of this device are as follows: When the antenna unit 1 is working in a high-temperature environment, if the heat dissipation fins 2 cannot meet the heat dissipation requirements, the fan 41 will ventilate and dissipate heat from the heat dissipation fins 2, thereby improving the heat dissipation efficiency of the heat dissipation fins 2 for the antenna unit 1. At the same time, the servo motor 33 drives the lead screw 34 to rotate, thereby driving the slider 32 to slide along the slide rail 31, thereby adjusting the position of the fan 41. By adjusting the position of the fan 41, it can fully dissipate heat from all positions of the heat dissipation fins 2. During the process of the fan 41 dissipating heat from the heat dissipation fins 2, the fan 41 is protected by the protective cover 42. During the process of the moving mechanism 3 driving the fan 41 to move in position, the mounting bracket 61 drives the wiping strip 62 to move with the fan 41. The wiping strip 62 wipes the surface of the heat dissipation fins 2 to prevent the surface of the heat dissipation fins 2 from being covered by dust. During the movement of the fan 41, the fan 41 will also drive the guide plate 55 to move. The arc-shaped chamfer of the guide plate 55 causes the scraper 54 to push the telescopic rod 51 and the spring 52 to compress. Then the scraper 54 will stick to the surface of the protective cover 42. Through the elasticity of the telescopic rod 51 and the spring 52, the scraper 54 will stick to the surface of the protective cover 42, and the dust on the surface of the protective cover 42 on the air intake side of the fan 41 will be scraped off, ensuring the ventilation and heat dissipation performance of the fan 41 for the heat dissipation fins 2.
