英伟达GB300NVL72服务器算力进一步提升,液冷散热需求迅速提升。英伟达今年即将 发布其专为AI推理时代而打造的AI服务器NVIDIA DGX GB300NVL72,AI算力进一步提 升,推论效能较DGX GB200提升了1.5倍。超高的芯片运算能力使得热设计功耗(TDP)进 一步提升,传统风冷散热技术热导率较低,难以满足较高TDP的散热需求,GB300服务器采 用了完全液冷式机架设计,引领了AI服务器液冷的新潮流。AI服务器液冷散热需求或将伴 随AI服务器出货量的提升而迅速提升。 现有液冷方案众多,主要包括冷板式、浸没式及喷淋式,高效液冷方案对氟化液材料依 赖较高。根据冷却液是否与电子器件直接接触,液冷可分为间接液冷与直接液冷;根据冷却 液工作过程中是否会发生液相变为气相的相变过程,可分为单相液冷与两相液冷。其中间接 液冷当前主流的形式是单相/两相冷板式液冷,直接液冷主要是单相/两相浸没式液冷与单相/ 两相喷淋式液冷。在这些液冷方案中,冷板式技术较为成熟,应用较为广泛,但是冷却效果 上限较低;浸没式和喷淋式液冷的冷却效果优异,但是经济成本较高,同时对使用材料要求 较高:由于冷却液与电子器件直接接触,因此 ...
