Key Questions
What is the projected market size for liquid cooling by 2033?
The liquid cooling market is forecast to reach $29.2 billion by 2033, growing at a 26.4% CAGR. This reflects the shift toward higher-density AI workloads requiring advanced thermal management.
What are the key features of Nvidia’s closed-loop liquid cooling system?
Nvidia’s system uses 45°C coolant with near-zero water consumption and delivers 40% less cooling energy. Hyperscalers have placed reservations through 2028 to support upcoming GPU deployments.
How is the CDU pump market expected to grow?
The CDU pump market is projected to reach $1.84 billion by 2032 at a 32.7% CAGR. Growth is driven by the need for reliable liquid cooling infrastructure at rack densities up to 227 kW.
What practical challenges do operators face when adopting liquid cooling?
Operators cite retrofit difficulties, evolving ownership boundaries between IT and facilities teams, and AC-to-DC conversion losses as key concerns. Many are shifting to 100% liquid cooling for next-generation Nvidia hardware.
How are vendors like Compass and Trane addressing water-free and hybrid cooling?
Compass emphasizes water-free cooling to maintain social license, while Trane offers hybrid solutions and lifecycle partnerships. Both collaborate with Nvidia on AI-ready data center designs.
Liquid cooling market forecast $29.2B by 2033, 26.4% CAGR.
