Data Center Liquid Cooling Market to Surge
The market for data center liquid cooling is projected to grow at a 28.7% compound annual growth rate, a new report finds. The rapid expansion is being driven by the escalating thermal loads from GPUs used for AI applications, sustainability mandates, and a structural shift toward liquid-first data center designs.
- Liquid cooling systems can achieve a Power Usage Effectiveness (PUE) ratio as low as 1.05, a measure of data center energy efficiency, compared to the 1.4 to 1.8 PUE typical for traditional air-cooled facilities. - The two primary liquid cooling methods are Direct-to-Chip (DTC), where liquid is piped directly to hot components like CPUs and GPUs, and immersion cooling, where entire servers are submerged in a non-conductive dielectric fluid. - Direct-to-chip cooling is the most widely adopted technique, compatible with existing server designs, while immersion cooling is the fastest-growing segment, noted for its superior thermal performance in high-density deployments. - Key companies in the market include established infrastructure providers like Vertiv and Schneider Electric, alongside specialists such as CoolIT Systems, Asetek, and LiquidStack. - The need for advanced cooling is driven by hardware like NVIDIA's H100/H200 and AMD's MI300X GPUs, which can generate over 700 watts of heat per chip—a thermal density that exceeds the physical limits of air cooling. - North America accounts for the largest market share, holding nearly 35.6% in 2025, due to the high concentration of hyperscale data centers operated by Google, Amazon Web Services, and Microsoft. - Government regulations are accelerating the transition, with examples like Germany's Energy Efficiency Act, which will require data centers to achieve a PUE of 1.3 or lower by 2027. - Water is a significantly more efficient heat transfer medium than air; it has approximately four times the heat capacity, meaning it can absorb four times more energy for the same temperature increase.
