Data Center Liquid Cooling Market Forecast to Grow 28.7% Annually
The market for data center liquid cooling is projected to grow at a compound annual growth rate of 28.7%, driven by widespread AI adoption and increasing GPU thermal loads. The industry is seeing a structural transformation towards liquid-first data center designs to manage the heat generated by high-density AI hardware.
- The two main competing technologies are direct-to-chip (D2C) and immersion cooling. D2C uses cold plates to pull heat from specific components like CPUs and GPUs, while immersion cooling submerges entire servers in a non-conductive fluid. D2C is often easier to retrofit into existing data centers, whereas immersion is more efficient but requires significant infrastructure changes. - Key companies dominating this market include Vertiv, Schneider Electric, and CoolIT Systems, who provide a range of solutions from coolant distribution units to direct-to-chip cold plates. These established players compete with specialists like Green Revolution Cooling, which focuses on single-phase immersion cooling technology. - NVIDIA now offers liquid-cooled versions of its data center GPUs, like the A100 and H100, responding to the thermal challenges of high-performance AI workloads. A liquid-cooled A100 GPU takes up only one PCIe slot, compared to two for the air-cooled version, effectively doubling the computing density in the same space. - Liquid cooling can significantly reduce a data center's Power Usage Effectiveness (PUE), a measure of energy efficiency. Air-cooled facilities often have a PUE between 1.4 and 1.8, while liquid cooling can lower that to as little as 1.05-1.15. - Benchmarks show that liquid-cooled NVIDIA GPU systems run significantly cooler, with GPU temperatures between 46-54°C compared to 55-71°C for air-cooled systems under identical AI workloads. This thermal stability allows for up to 17% higher computational throughput during stress tests because the GPUs can maintain higher clock speeds. - The shift is driven by staggering energy consumption; U.S. data centers used approximately 176 TWh in 2023, about 4.4% of the nation's total electricity. Projections indicate this could more than double by 2028, with cooling accounting for up to 40% of a data center's total energy load. - North America leads the market, accounting for over a third of the revenue, driven by the high concentration of hyperscale cloud providers like AWS, Google Cloud, and Microsoft Azure who are aggressively building out AI-ready facilities. - The adoption of liquid cooling also enables new opportunities for sustainability through heat reuse. The warm liquid exiting the systems can be used for applications like district heating, transforming data centers from energy consumers into contributors to local energy systems.
