Data Center Liquid Cooling Market Size

The global data center liquid cooling market size was valued at USD 4.34 billion in 2024 and is estimated to grow from USD 5.34 billion in 2025 to reach USD 27.72 billion by 2033, growing at a CAGR of 22.87% during the forecast period (2025–2033).

Data center liquid cooling refers to the use of liquid as a medium to transfer heat away from servers and other computing equipment in data centers. Unlike traditional air cooling, which relies on fans to circulate air, liquid cooling uses coolants to absorb and remove heat directly from the components. This method is highly efficient and is increasingly used in high-performance computing environments, where dense workloads generate significant heat.

Liquid cooling systems can be implemented in various forms, including immersion cooling, direct-to-chip cooling, and closed-loop systems, all of which offer better thermal management, lower energy consumption, and reduced environmental impact compared to conventional methods. The market is driven by the increasing need for efficient solutions due to the rising density of servers and the growing volume of data processed.

As data centers expand and handle more data-intensive tasks, the demand for effective thermal management solutions becomes critical to ensure optimal performance and prevent system overheating. Liquid cooling, being more efficient than traditional systems, allows for better heat dissipation in these high-density environments, reducing energy consumption and operational costs.
