385. 激光精确光子芯片冷却

from 知为谁 · host 知为谁

这篇文章出自 IEEE Spectrum,是世界上最大的专业工程和应用科学组织 IEEE 的旗舰出版物,讨论了一种名为光子冷却的创新技术,旨在解决高性能芯片过热的问题。 目前的芯片面临“暗硅”的限制,即大部分晶体管必须保持关闭状态以避免过热,但圣保罗的初创公司 Maxwell Labs 提出的解决方案是将热量直接转化为光(通过反斯托克斯荧光),从而实现从内到外、精确针对热点的冷却。 这种方法不仅有望彻底解决过热瓶颈,使芯片能以更高频率运行,还可能消除暗硅问题,并提高数据中心的能源效率,因为排出的光能可以被回收转化为电能。 虽然该技术仍面临材料优化、行业协同设计和商业化生产的挑战,但其目标是在 2027 年前在高性​​能计算中实现早期应用,并在 2030 年后广泛部署。内容来源:https://spectrum.ieee.org/laser-cooling-chips
