摘　　要：以某雷达液冷设备为研究对象,建立系统仿真模型,从供液温度和热冲击负载抗性等方面开展分析,揭示旁通管路开度及布置方式对设备工作特性的影响。结果表明,启动过程中,散热量随时间呈非线性上升趋势;旁通管路的开度对雷达负载的流量及供液温度均有影响,且旁通管路的布置方案与温度稳定性、热冲击抗性存在强相关,旁通管路与散热器并联可在高流量下提供更低的温度,而与雷达负载并联可提供更好的温度稳定性;在连续变化热负载下系统稳定性与旁通管路布置位置关联不大。Based on a certain radar liquid-cooling system,system simulation model is established,and analysis are conducted from the perspectives of supply liquid temperature and thermal shock load resistance to reveal the influence of the bypass pipe route and arrangement on the operating characteristics of the equipment.The results show that the open ratio of bypass valve affects the flow rate and supply liquid temperature of the radar load,and the arrangement scheme of the bypass pipe is correlated with temperature stability and thermal shock resistance.The bypass pipe arranged in parallel with the heat exchanger can provide a lower temperature at high flow rates,while the bypass pipes arranged in parallel with the radar can provide better temperature stability.The arrangement of bypass pipes is not closely related to the stability of the system under continuous changing thermal load.
