Dell’Oro examines competitive landscape of CDU market fueled by AI workloads.

The current growth in Artificial Intelligence (AI) is necessitating a shift from traditional air cooling to liquid cooling solutions in data centers. This change is largely driven by modern AI accelerators which are designed for liquid cooling, reflecting the evolving infrastructure requirements.

Market Overview

The transition to liquid cooling is becoming mainstream, as evidenced by a 156 percent increase in the Direct Liquid Cooling (DLC) market reported by Dell’Oro Group in 2Q 2025. Projections estimate this market could approach $6 billion by 2029, supported by increasing accelerated computing workloads.

Competitive Landscape

The surge in the liquid cooling market has attracted approximately 40 vendors, with a particular focus on coolant distribution units (CDUs). These players include established companies as well as newer entrants, reflecting diverse technical backgrounds and strategies in addressing the market demand.

Defining the CDU Role

Coolant distribution units function as essential components of liquid cooling systems, managing the necessary flow, pressure, and temperature. They are now integral to high-density racks targeting increased cooling efficiency in modern data centers.

Strategic Developments

Recent acquisitions indicate a consolidation trend in the Coolant Distribution Unit (CDU) market. Notable mergers and partnerships have been driven by larger physical infrastructure firms seeking to enhance their liquid cooling capabilities, demonstrating strategic interest in the sector.

Future Projections

While the current environment supports multiple competing vendors, market consolidation is anticipated as operations streamline. By the end of the decade, it is expected that the landscape will feature fewer than 10 dominant players, with the remainder reassessing their viability.

Success Factors for Vendors

Emerging leaders will need to adopt a systems-based approach, addressing the complexities of cooling solutions in data centers. Furthermore, understanding customer needs and maintaining rapid equipment availability will be crucial for gaining a competitive advantage.

Conclusion

This analysis highlights the ongoing evolution of the CDU market amidst the rising demands of AI infrastructure. The insights presented reflect the current dynamics essential for IT leaders and stakeholders to navigate this critical segment of the cooling market.
