Data centers generate immense localized heat, demanding thermal management beyond conventional HVAC systems.

数据中心产生大量局部热量，需要超越传统暖通空调系统的热管理方案。
Phase-change materials (PCMs) absorb or release large amounts of latent heat during solid–liquid transitions without significant temperature change.

相变材料（PCM）在固液相变过程中可吸收或释放大量潜热，且温度几乎不变。
Paraffin-based PCMs integrated into server rack walls buffer peak thermal loads during computational surges.

将石蜡基相变材料集成至服务器机柜壁中，可在计算负载激增时缓冲峰值热负荷。
Unlike traditional cooling, which responds reactively, PCM systems operate passively—storing excess energy until ambient conditions allow gradual dissipation.

与传统冷却方式的被动响应不同，相变材料系统主动储能，待环境条件允许时再缓慢释放多余热量。
This decoupling of heat generation and removal improves energy efficiency metrics like PUE by up to 12% in mid-tier facilities.

这种产热与散热过程的解耦，可使中型设施的电能使用效率（PUE）提升高达12%。
Urban data centers increasingly adopt PCMs to comply with municipal electricity curtailment policies during summer grid stress.

城市数据中心正越来越多地采用相变材料，以满足夏季电网承压期间地方政府的限电政策。
Material selection involves balancing melting point, thermal conductivity, and long-term cyclability—critical for 15-year infrastructure lifespans.

材料选型需兼顾熔点、导热系数及长期循环稳定性——这对长达15年的基础设施寿命至关重要。
Thermal modeling must account for hysteresis effects, where solidification lags behind cooling due to nucleation barriers.

热建模必须考虑滞后效应：因成核能垒，固态化滞后于降温过程。
Global cloud providers now specify PCM performance thresholds in vendor contracts, treating them as thermal capacitors rather than mere insulation.

全球云服务商已在供应商合同中明确相变材料性能指标，将其视为热容元件，而非单纯隔热材料。
Cross-border deployment requires recalibration for regional humidity levels, which affect PCM condensation dynamics and corrosion risks.

跨境部署需根据区域湿度水平重新校准，因湿度影响相变材料冷凝动力学及腐蚀风险。
From an engineering ethics perspective, PCM integration reflects growing recognition that sustainability demands rethinking thermodynamics—not just energy sources.

从工程伦理角度看，相变材料的应用反映出业界日益认识到：可持续发展不仅关乎能源来源，更需重构热力学设计逻辑。
Their quiet operation also supports noise-sensitive urban colocation sites where acoustic compliance precedes thermal design.

其静音运行特性也契合对噪声敏感的城市托管机房需求——声学合规性优先于热设计。
