摘要
2019年6月,我国5G商用网络正式启用,随之而来是大面积、大规模的5G基站建设。在基站建设过程中,国内各家运营商积极探索研发了CRAN模式助力5G基站建设,基本实现了3G、4G、5G BBU数据资源的集中布局与释放,大量节省了5G承载商用网络的运营成本费用,为未来进一步与BBU协同技术开展创造了有利条件。但是,该阶段5G BBU设备运行功耗高,因为它最多集成了8个BBU,使得CRAN机房的机柜散热变得困难。因此,探究CRAN机房相关技术布局和CRAN机房机柜散热理论,着重探究了CRAN机柜散热的应用实践。
In June 2019,5G commercial network was officially launched in China,followed by large-scale 5G base station construction. In the process of base station construction,domestic operators have actively explored and developed the cran mode to assist the construction of 5g base station. It basically realizes the centralized layout and release of 3G,4G and 5G BBU data resources. At the same time,the construction of cran room also saves a lot of operating costs of 5G carrying commercial network,creating favorable conditions for further cooperation with BBU in the future. At this stage,of course,we must face up to the problem that 5G BBU is quite high in the performance of equipment operation power consumption,because it integrates up to eight BBus,which makes the cabinet heat dissipation of cran machine room a technical problem. Therefore,this paper first explores the technical layout of cran machine room,the cooling theory of cran machine room cabinet,and finally focuses on the application of cran cabinet cooling.
