What's Happening?
The global data center cooling market is projected to reach USD 109.23 billion by 2035, growing at an impressive Compound Annual Growth Rate (CAGR) of 18.0% from 2026 to 2035. The market was valued at USD 20.87 billion in 2025 and is estimated at USD 24.63
billion in 2026. This significant growth is primarily driven by the escalating heat loads generated by Artificial Intelligence (AI) and high-performance computing (HPC) applications, which are pushing rack densities beyond the capabilities of traditional air cooling. North America currently holds the largest share of the market, accounting for approximately 39.2% of global revenue in 2025, largely due to the presence of major hyperscale and AI training campuses in the United States. Liquid cooling solutions, particularly direct-to-chip technology, are becoming mainstream, with NVIDIA's fully liquid-cooled Vera Rubin platform entering full production in early 2026.
Why It's Important?
The rapid expansion of the data center cooling market is critical for the continued growth of the digital economy in the U.S. and globally. As AI and HPC workloads become more prevalent, efficient cooling solutions are essential to prevent hardware failures, ensure operational reliability, and manage the immense energy consumption of data centers. The shift towards liquid cooling, especially direct-to-chip and immersion cooling, directly impacts the design and infrastructure investments of U.S. tech giants and cloud providers. This trend also has significant implications for energy efficiency and sustainability, as liquid cooling can achieve much lower Power Usage Effectiveness (PUE) values compared to air-cooled systems. For the U.S., which hosts the world's largest hyperscale and AI training campuses, the adoption of advanced cooling technologies is vital for maintaining technological leadership, reducing environmental footprint, and addressing grid and water constraints.
What's Next?
The data center cooling market will continue to evolve with several key trends. Liquid cooling is expected to become fully mainstream, with direct-to-chip cold plates being the preferred initial step due to their compatibility with standard racks. AI racks will redefine thermal design, with rack power densities increasing significantly, making liquid cooling mandatory. Efficiency gains will increasingly depend on liquid cooling, with PUE values dropping further. The market will also see accelerated consolidation, with major electrical and HVAC companies acquiring liquid cooling specialists, as evidenced by recent acquisitions like Ecolab's purchase of CoolIT Systems and Trane Technologies' acquisition of LiquidStack. Furthermore, water-free and closed-loop designs will gain priority due to water scarcity, and waste heat reuse, coupled with AI-driven controls, will become more common to improve energy efficiency and sustainability.
Beyond the Headlines
The transformation in data center cooling extends beyond technological advancements, touching upon broader environmental, economic, and regulatory landscapes. The push for water-free and closed-loop cooling designs highlights growing concerns over water scarcity and the environmental impact of data centers, particularly in water-stressed regions of the U.S. The ability to reuse waste heat from data centers for district heating networks or industrial processes presents a significant opportunity for energy recovery and circular economy initiatives, potentially turning a cost center into a revenue or sustainability asset. This shift could influence urban planning and infrastructure development, fostering greater integration between data centers and local communities. Moreover, the increasing complexity of liquid cooling systems will necessitate new skill sets in the workforce, driving demand for specialized engineers and technicians, and potentially leading to new educational and training programs.
