Direct Liquid Cooling to Revolutionize AI Compute at Scale
Direct Liquid Cooling (DLC) is set to revolutionize AI compute at scale, as air cooling struggles to handle more than 20% of the load. AI, despite increasing energy use, can optimize total Power Usage Effectiveness (PUE) and drive ROI with smart cooling and energy management. The shift towards DLC and hybrid systems is expected to accelerate between 2026 and 2027, aligning with global AI infrastructure buildouts.
At the upcoming Tech Show Paris (5–6 November, Paris Expo Porte de Versailles), attendees can expect insights into hybrid cooling architectures and real-world deployment learnings. Experts will discuss PUE optimization, with new liquid-cooled systems achieving ratios as low as 1.2. This session is a must-attend for infrastructure managers, cloud architects, and facilities directors facing density challenges from AI, HPC, and immersive tech.
Professionals building facilities today should prepare for these changes, as designs are being finalized and execution will accelerate in the near future. Stulz, a leading provider of data centre cooling systems, will explore the shift towards DLC and hybrid systems at Data Centre World Paris. The acceleration of AI and increasing GPU power is putting pressure on legacy data centre infrastructure, with cooling being a key challenge. Didier Ronsen, Managing Director of Stulz France, will lead a session on adapting data centres to rising heat challenges at the Tech Show Paris.
Data centre cooling densities have increased significantly, from 5kW per rack to hitting 1MW, making traditional air cooling insufficient. The shift towards Direct Liquid Cooling and hybrid systems is necessary for sustainable AI compute at scale. Professionals should prepare for these changes and attend industry events like Tech Show Paris to stay informed and adapt their strategies accordingly.
