The fast development of artificial intelligence, cloud computing, and high-performance computing is rapidly changing the whole scenario of cooling for the world's data centres. Not only are modern data centres not constrained by just supporting enterprise workloads but now have the capability to perform GPU-intensive AI training, AI inference systems and edge computing that produce very high heat density. Consequently, the use of air cooling has hit its ceiling and is forcing the industry towards liquid cooling, direct chip cooling and even immersion cooling.
In today’s scenario, data centers account for a considerable amount of electricity consumption, where the amount of electricity used for cooling accounts for around a third to almost half of the entire energy consumed. Efficient cooling systems have emerged as critical investments with the increase in infrastructure expansion by hyperscale players and workloads pushing power densities above 30 to 60 kW per rack.
The data center cooling market size was estimated at USD 20.73 billion in 2025 and is anticipated to reach USD 83.54 billion by 2035, growing at a CAGR of 14.99%. The growth is highly influenced by the expansion of AI infrastructure, sustainability requirements, and increasing demand for efficient cooling solutions in hyperscale, colocation, and edge data centers.
