Global Data Center Liquid Cooling Market Size, Share & Forecast, By Cooling Type, Data Center Type & End-Use Industry, 2026-2031

The Global Data Center Liquid Cooling Market was worth USD 2.3 billion in 2025. The estimate covers direct-to-chip systems, immersion cooling, rear-door heat exchangers, cold plates, coolant distribution units, coolants, controls, integration and associated services. Direct-to-chip cooling represented the largest commercial revenue pool because it can support high-density AI hardware while retaining conventional rack formats. Market development was concentrated in hyperscale, colocation and HPC facilities, with enterprise deployments remaining more selective because many existing sites still operate below the density threshold requiring facility-level liquid infrastructure.

The market is projected to grow at a CAGR of 29.00% during 2026-2031 and reach USD 10.6 billion by 2031. Growth is supported by AI training clusters, expanding inference capacity, higher processor thermal design power and the integration of liquid cooling into server and rack reference architectures. Deployment volume is expected to grow faster than average system revenue as manufacturing scale and standardized components reduce unit costs. However, larger CDUs, redundant pumping, controls, commissioning and lifecycle services will preserve overall contract values and broaden vendor revenue beyond individual cold plates.

Profit pools will shift from standalone cooling hardware toward integrated thermal chains and recurring services. Cold plates and CDUs remain essential, but customers increasingly require manifolds, heat exchangers, controls, coolant management, commissioning and maintenance under coordinated responsibility. This favors suppliers able to design from chip to facility heat rejection and support systems throughout their lifecycle. The transition also increases the strategic value of fluid-management and field-service businesses, as demonstrated by premium acquisition activity. Specialist vendors can retain attractive margins where proprietary thermal performance, reliability validation or OEM integration differentiates their offerings.

Retrofit complexity is the most material near-term constraint. Liquid cooling changes responsibility boundaries between IT equipment teams and facility operators, introduces fluid-quality and leak-management requirements, and can require new piping, heat exchangers and redundancy strategies. Although 61% of surveyed organizations not using direct liquid cooling would consider it, only 22% reported current use in 2024. Many enterprise racks also remain within the range that air cooling can support economically, reducing urgency outside AI, HPC and other concentrated compute workloads.

North America is the largest current opportunity, while Asia Pacific and the Middle East and Africa offer stronger percentage growth. North America represented an estimated USD 1.012 billion in 2025 because of its hyperscale concentration, AI infrastructure pipeline and mature data center supply chain. Asia Pacific is projected to grow at 33.0%, supported by China and emerging capacity in India, Japan, Australia and Southeast Asia. The Middle East and Africa is expected to grow at 36.0% from a smaller base as sovereign cloud and AI infrastructure programs expand.

Rack-level heat density has the greatest direct influence because it determines whether air systems can remove heat economically and reliably. NVIDIA's GB200 NVL72 combines 72 GPUs in a liquid-cooled rack consuming approximately 120 kW, far above traditional enterprise rack densities. As accelerated-server electricity consumption grows, operators must either deploy direct liquid cooling, redesign workloads across more floor space or accept performance constraints. Liquid cooling therefore supports both thermal management and data center economics by increasing compute capacity per rack, improving floor-space utilization and reducing auxiliary cooling loads.
