01 Development of Two-Phase Liquid Cooling Technologies The data center cooling system market trends show that higher server power densities and heat loads are shifting cooling technology toward two-phase liquid systems that remove heat through liquid-to-vapor phase changes. This transition can reduce dependence on compressor-based air cooling, with an ARPA-E-supported IBM project targeting more than 90% lower cooling energy consumption and the potential to eliminate water use compared with conventional compressor-based air cooling. The outcome is greater development of two-phase cooling architectures for high-performance computing and AI data centers where conventional air systems face thermal limits.
02 Adoption of Rear-Door Heat Exchangers for High-Density Racks The data center cooling system market trends show that concentrated heat loads from high-density racks are shifting operators toward rear-door heat exchangers that remove heat directly from server exhaust before it enters the data-center space. This transition supports higher rack densities while reducing the thermal burden on room-level cooling systems, and the U.S. Department of Energy identifies rear-door heat exchangers as a liquid-cooling approach that captures server heat close to the rack source. The outcome is greater adoption of rack-level cooling for AI and high-performance computing environments, with ASHRAE guidance identifying rear-door heat exchangers as suitable for 50–100+ kW rack densities.
01 Surging Data Center Power Consumption and Expansion of Modular Cooling Solutions Drive Market Surging data center power consumption is increasing the thermal management requirements of data center facilities, creating stronger demand for efficient cooling systems. The International Energy Agency estimates that data centers consumed 415 TWh of electricity in 2024, equal to around 1.5% of global electricity consumption, and projects demand to reach about 945 TWh by 2030. Higher power densities from AI and high-performance computing therefore increase cooling requirements and encourage operators to deploy advanced temperature-control infrastructure. For example, AI-focused facilities require specialized cooling capacity to manage the heat generated by high-density GPU servers.Expansion of modular cooling solutions is strengthening the supply of scalable cooling infrastructure for data centers with changing capacity requirements. Uptime Institute notes that modular construction allows capacity to be added in separate blocks over time, with each expansion supported by self-contained infrastructure such as cooling equipment. This approach allows operators to match cooling capacity with incremental IT deployment while reducing the need for oversized infrastructure during initial construction. For example, a data center can add modular chiller or cooling units as additional server halls become operational, supporting phased capacity growth.
01 Water Constraints and Space Limitations Restrain Data Center Cooling System Market Expansion Water consumption and availability constraints can limit the use of water-based cooling systems, particularly in water-stressed regions. A U.S. Department of Energy-supported Lawrence Berkeley National Laboratory report estimates that U.S. data centers could directly consume 145–275 billion liters of water annually by 2028, up from about 70–90 billion liters in 2024. These requirements can increase operating costs and restrict new cooling installations where water availability is limited.Space constraints in high-density data centers make it difficult to accommodate additional cooling equipment, piping, heat exchangers, and supporting infrastructure. The IEA reports that cooling can account for about 7% of electricity use in efficient hyperscale data centers and more than 30% in less-efficient enterprise facilities, highlighting the infrastructure required to manage thermal loads. Limited space can complicate cooling upgrades, increase installation complexity, and slow adoption of advanced data center cooling systems.
01 Two-Phase Liquid Cooling Technologies and Rear-Door Heat Exchangers Create New Market Opportunities Hyperscale data centers, AI computing facilities, data-center operators, and cooling-system manufacturers can benefit from two-phase liquid cooling for high-density computing environments. Companies such as 3M and Schneider Electric have developed liquid-cooling technologies, creating revenue through specialized cooling systems, coolants, infrastructure upgrades, and service contracts while supporting data center cooling market growth.Data-center operators, colocation providers, and server manufacturers can benefit from rear-door heat exchangers that remove heat directly from high-density racks without major changes to existing facility layouts. Companies such as Vertiv and CoolIT Systems offer rear-door and liquid-cooling solutions, creating revenue through retrofit projects, heat-exchanger equipment, installation, and maintenance services while supporting data center cooling market growth.
01 High Energy Demand and Rising Thermal Density Hinder Data Center Cooling System Market Growth High energy demand from cooling infrastructure increases operating pressure on data center operators and limits the efficiency gains available from new facilities. The International Energy Agency estimates that global data center electricity consumption could reach around 945 TWh by 2030, more than doubling from 2024 levels, increasing the need for highly efficient cooling technologies.Rising thermal density from AI accelerators and high-performance computing makes conventional cooling configurations less effective and increases the need for liquid or hybrid systems. NVIDIA’s GB200 NVL72 rack-scale system, for example, integrates 72 Blackwell GPUs in a single rack and requires liquid cooling, illustrating how AI workloads are creating new deployment and retrofit requirements for data center cooling providers.
