Problems solved by technology

Therefore, in the 5G era, the calculation power consumption of the base station will be greatly increased and exceed the transmission power consumption.
[0004] The increase in computing power consumption of 5G base stations brings not only power consumption problems, but also heat dissipation problems
However, with the increase of computing power consumption of 5G base stations, the use of air conditioners for heat dissipation will bring more heat dissipation power consumption. At the same time, with the development of 5G edge computing and high-speed local cache, small base stations suspended on urban light poles In the future, more and more data storage and computing functions will be performed. However, the use of air-conditioned computer rooms is not suitable for the heat dissipation of small base stations in this environment.

Description

technical field [0001] The invention relates to a heat dissipation system for a 5G base station. Background technique [0002] At present, with the vigorous growth of VR / AR, autonomous driving, robots, video surveillance and other applications, a data tsunami is coming along with the 5G intelligent connection of all things, and the power consumption caused by massive data will also double. increase. The communications industry is expected to consume 20% of the world's electricity by 2025. Electricity has been identified by some operators as the highest OPEX expenditure, accounting for at least 15% of the operator's total operating costs. In mobile communication networks, base stations are major power consumers, and about 80% of the energy consumption comes from widely distributed base stations. More dense base stations mean higher energy consumption, which is a major cost challenge for 5G networks. [0003] The base station, that is, the public mobile communication base s...
