摘　　要：对3个高速连接器的拓扑和4个高速连接器的拓扑分别在液冷环境和风冷环境中的信号质量进行仿真。在液冷环境中,对4个高速连接器的拓扑中高速连接器间间距进行仿真。仿真结果表明:风冷环境下PCIe 5.0 Tx链路的信号质量优于液冷环境下PCIe 5.0 Tx链路的信号质量;高速连接器个数对液冷环境下PCIe 5.0 Tx链路的信号质量影响较风冷环境下更大;优化后的高速连接器间间距可以改善液冷环境下PCIe 5.0 Tx链路的信号质量。The signal quality of three high-speed connector topologies and four high-speed connector topologies in liquid cooling and air cooling environments is simulated.The space between high-speed connectors in four high connector topologies is simulated in liquid cooling environment.The simulation results show that the signal quality of PCIe 5.0 Tx channel in air cooling environment is better than that in liquid cooling environment.The number of high-speed connectors has a greater impact on the signal quality of PCIe 5.0 Tx channel in liquid cooling environment than that in air cooling environment.The optimized space between high-speed connectors can improve the signal quality of PCIe 5.0 Tx channel in liquid cooling environment.
