5G CRAN机房机柜热管理研究

Research on Thermal Management of 5G CRAN Computer Room Cabinet

随着5G从2019年6月6日起正式商用,5G基站大规模建设随之而来。运营商探索采用CRAN模式开展5G基站建设,将2G/4G/5G BBU集中布放。CRAN基站建设的好处是能够节省机房的租赁费和电费,未来也易开展BBU协同,但是也面临诸多问题。除了建设方面的难题外,5G BBU功耗较高。集成4~8个BBU,如何解决设备散热问题值得探索。因此,将通过案例研究BBU集中布放后的散热管理,解决设备安全运行问题,同时借鉴微模块技术降低基站的电费,实现企业的长远发展。

With the official commercialization of 5 G from June 6,2019,large-scale construction of 5 G base stations has followed.Operators explored the use of CRAN mode to build 5 G base stations and centralize 2 G/4 G/5 G BBUs.The advantage of CRAN base station construction is that it can save the rental fee and electricity cost of the equipment room.It is easy to carry out BBU coordination in the future,but it also faces many problems.In addition to the construction challenges,the 5 G BBU consumes more power.Integrating 4 to 8 BBUs,how to solve the problem of device heat dissipation is worth exploring.Therefore,through the case study,the thermal management of the BBU will be deployed in a centralized manner to solve the problem of safe operation of the equipment.At the same time,the micro-module technology will be used to reduce the electricity cost of the base station and realize the long-term development of the enterprise.
