Description

Technical Field

[0001] The present invention relates to the technical field of base station cooling, and specifically to a cooling device for a 5G base station. Background Art

[0002] 5G base stations are the core equipment of 5G networks, providing wireless coverage and realizing wireless signal transmission between wired communication networks and wireless terminals. The architecture and form of base stations directly affect how 5G networks are deployed. In technical standards, the frequency band of 5G is much higher than that of 2G, 3G and 4G networks. At this stage, 5G networks mainly operate in the 3000-5000MHz frequency band. Since the higher the frequency, the greater the attenuation during signal propagation, the base station density of 5G networks will be higher.

[0003] As my country's network coverage becomes wider and wider, the number of 5G base stations built is also increasing to ensure normal network communication. At present, 5G base stations are generally built directly in open-air environments. This will cause the antennas on the base stations to have high temperatures in hot weather, thus affecting the normal use of 5G base stations. Although some base stations will be built with fans for cooling, the antennas on the base stations are installed in different positions, making it impossible to cool multiple antennas at the same time.

[0040] Working principle:

[0041] First, under normal temperature and when the outdoor wind is strong, the unpowered wind ball 7 can drive the rotating rod 8 to rotate by wind force, and the rotating rod 8 drives multiple sets of fan blades 9 to rotate, which can blow air around the column 4, thereby blowing air to cool down multiple antenna bodies 1, and there is no need to start the one-way driving mechanism, saving energy. When the weather is hot, start the servo motor 10, and the output shaft of the servo motor 10 drives the rotating rod 8 to rotate through the first overrunning clutch 11, and the rotating rod 8 drives multiple sets of fan blades 9 to rotate, which can blow air from the column 4 to the surroundings, thereby blowing air to cool down the antenna body 1 around the column 4, and when the rotating rod 8 is rotating, the rotating rod 8 drives the circular plate 16 to rotate, which will cause multiple round rods 17 to slide reciprocatingly in the annular groove, and the multiple round rods 17 respectively drive the multiple rack rods 14 to move back and forth, and the rack rod 14 drives the spur gear 15 to rotate reciprocatingly, and because the first The first rotating shaft and the second rotating shaft are connected to each other through the second overrunning clutch 13. When the spur gear 15 rotates forward, it can drive the first rotating shaft and the fan blades 12 to rotate forward. When the spur gear 15 rotates reversely, the first rotating shaft and the fan blades 12 do not rotate, so that the hot air inside the antenna housing 2 can be discharged to the outside, thereby improving the cooling effect. At the same time, through the refrigeration compressor 25 and the semiconductor refrigeration plate 26, refrigeration can be performed and cold air can be introduced into the antenna housing 2 through the semiconductor refrigeration plate 26. In combination with the wind blown out from the column 4, the antenna body 1 is further cooled to improve the cooling effect. In addition, when the unpowered wind ball 7 drives the rotating rod 8 to rotate, it can generate electricity through the small wind turbine 21, and then store electricity. The stored electricity can be used for the servo motor 10 and the refrigeration compressor 25 to save energy. At this point, the entire work process ends.
