摘　　要：作为解决未来智算中心高能耗问题的液冷散热技术,因其散热系统的特殊性,管道系统腐蚀成为系统失效的重要因素之一。通过对以往液冷管道系统腐蚀案例及机理分析,并采用失重法对散热冷板常用材料进行兼容性实验验证。分析结果表明,铝合金材质在液冷系统中较易被腐蚀,铜材质冷板在恶劣环境中的耐腐蚀性较好,且与不锈钢材质管道有良好的兼容性。此外,液冷系统对冷却介质的要求较高,应严格控制液冷系统内冷却介质的各项指标,建立长效化监测、预警、管理和运行控制机制,提高液冷管道系统腐蚀控制水平。As a liquid cooling heat dissipation technology to solve the problem of high energy consumption in future intelligent computing center,pipeline system corrosion has become one of the important factors of system failure because of the particularity of the heat dissipation system.Based on the analysis of the corrosion cases and mechanism of the liquid cooling pipeline system in the past,the compatibility test of the common materials of the cooling plate is carried out by using the weight loss method.The analysis results show that aluminum alloy is easy to be corroded in liquid cooling system,copper cold plate has good corrosion resistance in harsh environment,and has good compatibility with stainless steel pipe.In addition,the liquid cooling system has higher requirements for the cooling medium,and the indicators of the cooling medium in the liquid cooling system should be strictly controlled,and a long-term monitoring,early warning,management and operation control mechanism should be established to improve the corrosion control level of the liquid cooling system pipeline.
