According to Fortune Business Insights, the global data center cooling market size was valued at USD 18.8 billion in 2025 and is projected to grow from USD 21.0 billion in 2026 to USD 54.4 billion by 2034, exhibiting a CAGR of 12.6% during the forecast period. The market is experiencing strong growth as data center operators increasingly deploy artificial intelligence (AI), cloud computing, high-performance computing (HPC), and hyperscale infrastructure. These applications generate substantial heat and require advanced thermal management technologies to maintain operational reliability, energy efficiency, and equipment performance.
Data center cooling refers to the technologies and infrastructure used to control temperature, humidity, airflow, and heat dissipation inside data centers. Servers, storage systems, networking equipment, GPUs, and other computing infrastructure generate significant amounts of heat during operation.
Effective cooling systems remove this heat and maintain appropriate environmental conditions. Common technologies include air conditioners, precision air conditioners, air handling units, chillers, liquid cooling systems, heat exchangers, cooling towers, containment solutions, and advanced monitoring platforms.
Cooling infrastructure is essential for maintaining server performance, preventing equipment failure, improving energy efficiency, and supporting uninterrupted data center operations.
The rapid expansion of digital infrastructure is creating strong demand for efficient cooling technologies. Organizations are investing heavily in cloud services, AI infrastructure, enterprise data centers, colocation facilities, and edge computing networks.
The global market was worth USD 18.8 billion in 2025 and is expected to reach USD 54.4 billion by 2034. The market is forecast to expand at a CAGR of 12.6% between 2026 and 2034. North America accounted for the largest share, representing 38.72% of the global market in 2025.
Liquid cooling is emerging as one of the most important trends in the market. Conventional air-cooling technologies face limitations as rack power densities increase due to AI accelerators, GPUs, and high-performance processors.
Liquid cooling can remove heat more efficiently and support high-density computing environments. The liquid cooling segment is expected to register the highest growth rate, with a CAGR of 15.1% during the forecast period.
