随着人工智能、高性能计算的快速发展,冷板式液冷技术已逐渐成为应对高密度数据中心冷却系统散热需求的主流技术方案之一。本文介绍了数据中心冷板式液冷系统典型故障的诱发机理、影响危害与耦合演化规律;总结了直接检测技术和基于运行数据的反问题故障诊断技术的原理及特点,并梳理了这类故障诊断技术在冷板式液冷系统实际应用中存在的关键问题;基于暖通空调领域的诊断经验,归纳了现有问题的针对性改进方法,例如半监督学习、小样本学习、数据增强、物理与数据融合等。未来该领域的研究可围绕多算法融合、缓解数据不平衡问题、增强模型可解释性和抗干扰能力等方向,提升故障识别的准确性、可靠性和工程适用性。本文对相关研究的梳理与归纳,可为冷板式液冷故障诊断领域的理论研究与工程应用提供参考。
With the rapid development of artificial intelligence and high-performance computing, cold-plate liquid cooling technology has gradually become a mainstream solution for satisfying the heat-dissipation demands of high-heat fluxes data centers. This paper describes the triggering mechanisms, impact hazards, and the coupled evolution patterns of typical faults in data center cold-plate liquid cooling systems. The principles and characteristics of direct-detection techniques and inverse-problem fault diagnosis techniques are then summarised based on operational data and outlines the key problems encountered when applying these diagnostic techniques to real-world cold-plate liquid cooling systems. Finally, based on diagnostic experience in the HVAC (heating, ventilation and air conditioning) field, this study concludes the targeted methods for addressing these problems, including semi-supervised learning, few-shot learning, data augmentation, and physics-data fusion. Future research could focus on multi-algorithm fusion, mitigating data imbalance, and enhancing model interpretability and anti-interference capabilities to improve the accuracy, reliability, and engineering applicability of fault identification. The review and synthesis presented in this paper can serve as a reference for both theoretical research and engineering applications in the field of cold-plate liquid-cooling fault diagnosis.
