Data center liquid cooling market to hit $40.25 billion by 2035

Data center liquid cooling demand is accelerating as AI, GPU-heavy workloads and high-density computing strain traditional air-based systems. The market is projected to grow from $5.90 billion in 2025 to $40.25 billion by 2035, with North America leading and Asia-Pacific showing the fastest growth potential.

Why it matters: - AI servers and high-density computing are pushing data center cooling systems past the limits of conventional air cooling. - Liquid cooling can remove heat more efficiently, helping operators improve energy efficiency, reliability and rack density. - The market’s rapid growth reflects a broader redesign of data center infrastructure around power-hungry workloads.

What happened: - The data center liquid cooling market was valued at $5.90 billion in 2025. - The market is projected to reach $7.24 billion in 2026 and $40.25 billion by 2035. - The forecast implies a 21.0% CAGR from 2026 to 2035. - Demand is rising across hyperscale data centers, colocation sites, enterprise infrastructure and high-performance computing environments. - Download the sample report for more details.

The details: - Direct-to-chip cooling, immersion cooling and rear-door heat exchangers are gaining traction as operators look for scalable thermal management. - Direct-to-chip systems move heat from CPUs, GPUs or accelerators into a liquid loop. - Immersion cooling places computing equipment in a non-conductive liquid to improve heat transfer. - Rear-door heat exchangers capture heat at the rack and move it away through liquid-cooled hardware. - Energy use is a major driver, since cooling can account for a significant share of facility electricity consumption. - Liquid cooling can also support sustainability goals, including lower cooling energy use, better water management and improved power usage effectiveness. - Heat recovery may allow captured thermal energy to be reused for district heating or industrial processes in some regions. - North America held about 42% of revenue share in 2025. - Europe held about 26% of revenue share in 2025. - Asia-Pacific is expected to post a 24.8% CAGR from 2026 to 2035. - South America generated about $0.30 billion in 2025. - The Middle East and Africa market is projected to grow at a 22.0% CAGR from 2026 to 2035. - Browse the full market report.

Between the lines: - AI infrastructure is changing how data centers are designed, not just how they are cooled. - New facilities can bake liquid cooling into the initial build, while older sites may need retrofit solutions and more complex infrastructure changes. - The competitive edge is shifting toward vendors that can combine hardware, monitoring, controls and integration across the full cooling stack. - Challenges remain, including higher upfront complexity, maintenance needs and compatibility issues in existing buildings.

What's next: - Purpose-built AI data centers are likely to drive more direct liquid cooling deployments. - Retrofit demand should grow as operators look to upgrade air-cooled facilities without major downtime. - Cooling vendors are expected to keep investing in coolant innovation, thermal-management software and integrated system monitoring. - Hybrid cooling architectures may become more common as operators mix air and liquid systems for different workload types.

The bottom line: - Liquid cooling is moving from a niche option to a core requirement for high-density, AI-driven data center design.
