摘　　要：随着服务器集成度不断提高,功率密度也逐渐增大,其散热问题成为制约服务器发展的一大障碍。与风冷相比,液冷具有良好的散热优势,在未来更高功率密度服务器散热过程中具有重要应用前景。另外液冷技术可以有效降低数据中心的PUE值,减少碳排放。基于此,通过实验研究了某国产双路服务器散热性能。首先,通过实验对比了该服务器的风冷与液冷散热效果。然后,通过对比内/外循环液冷性能,发现外循环液冷散热具有更大的散热调控性能,控温范围更广泛,适合的应用场景也更丰富。在较低进水温度和较大进水流量下,外循环液冷能够获得更好的散热效果。With the continuous improvement of server integration and the gradual increase in power density,the problem of heat dissipation has become a major obstacle to the development of servers.Compared with air cooling,liquid cooling has good heat dissipation advantages and has important application prospects in the heat dissipation process of higher power density servers in the future.In addition,liquid cooling technology can effectively reduce the PUE value of the data center and reduce carbon emissions.Based on this,this paper studies the heat dissipation performance of a domestic dual-socket server through experiments.Compared with traditional air cooling,liquid cooling has better heat dissipation effect.Further,by comparing the internal/external circulation liquid cooling performance,it is found that the external circulation liquid cooling has greater heat dissipation regulation performance,wider temperature control range,and more suitable application scenarios.At lower inlet water temperature and larger inlet water flow,the external circulation liquid cooling can obtain better heat dissipation effect.
