AI Servers to Feature Diamond Heat Sinks and Liquid Cooling

A new thermal management solution for high-end AI servers is emerging, combining diamond heat sinks with full liquid cooling. This approach addresses the increasing power consumption and heat generation of GPUs like NVIDIA's H100, Blackwell, and Rubin series, which are pushing the limits of traditional copper and aluminum materials. Diamond's superior thermal conductivity will help dissipate heat directly from the chips, while liquid cooling will manage system-level heat removal, creating a complementary system for advanced AI hardware. AI

IMPACT This advanced cooling solution could enable more powerful AI hardware, potentially accelerating the development and deployment of next-generation AI models.

    CICC: Future high-end AI servers are expected to adopt a composite cooling solution of "diamond heat sink + full liquid cooling"

    36氪获悉,中金公司研报认为,近端散热与液冷形成互补体系,当前H100、Blackwell、Rubin系列GPU功耗持续突破千瓦级,3D封装进一步抬升芯片局部热流,铜铝材料热传导瓶颈凸显;金刚石具备2000W/m・K级别超高热导率、低热膨胀系数,可快速摊平芯片热点。产业落地层面,金刚石负责芯片近端均热扩散,液冷承担机柜系统级排热,二者并非替代关系,未来高端AI服务器有望采用“金刚石热沉+全液冷”复合散热方案。
