摘　　要：文中针对高热流密度5G路由器开发了液冷散热样机,介绍了液冷系统关键部件的设计,同时对设计的液冷系统开展了仿真评估和回归分析。测试结果表明:在设计流量下,液冷系统满足芯片散热要求,系统流阻匹配性良好,同时仿真结果与实测数据误差不超过10%。最后从电能使用效率(Power Usage Effectiveness,PUE)角度对路由器液冷散热系统解决方案进行了收益评估。结果表明:机房PUE小于1.25,若采用纯液冷解决方案,机房PUE将降至1.15,规模化应用收益更高,适合承载网与服务器产品。A liquid cooling prototype developed for the 5G router with high heat flux density is introduced in this paper.The design of the key components of the liquid cooling system is shown.At the same time,simulation evaluation and regression analysis of the designed liquid cooling system are carried out.The test results show that under the designed flow rate,the chip heat dissipation requirements are reached,the system flow resistances match well and the deviation between the simulation results and the measured data is not more than 10%.At last,the benefit of the router liquid cooling system is evaluated from the perspective of power usage effectiveness(PUE).The results show that the PUE of the equipment room is less than 1.25.If the pure liquid cooling solution is adopted,the PUE will be reduced to 1.15.The application in transport network and server products will benefit more from the large-scale use.
