The Rise of Liquid Cooling: A Vital Component in the AI Revolution
The insatiable appetite of artificial intelligence (AI) is pushing technology giants like Nvidia to seek innovative solutions for their data centers, and one technology is emerging as a critical player: liquid cooling. As the power demands of AI workloads continue to soar, traditional air-cooling methods are reaching their limitations, prompting a shift towards liquid cooling systems for more efficient and cost-effective solutions. This trend is attracting significant attention from investors and analysts, who see major growth potential in this area.
Key Takeaways:
- AI’s Computational Intensity: The exponential growth of AI workloads is driving the demand for more powerful computing systems, intensifying the need for efficient cooling solutions.
- Liquid Cooling’s Rise: As air cooling reaches its capacity, liquid cooling is becoming a crucial technology for AI data centers, offering significant benefits in terms of power and cost efficiency.
- Market Shift and Investments: Major tech firms like Nvidia are incorporating liquid cooling into their hardware, and analysts are recognizing its importance, leading to investments in companies specializing in this technology.
- Asian Players Leading the Way: Firms like AVC, Auras, Delta, and Nidec are emerging as key beneficiaries of the rising demand for liquid cooling solutions for the AI industry.
Why Liquid Cooling is Crucial for AI
The continuous development of AI algorithms and the growing adoption of AI applications across various industries have led to an explosive growth in AI workloads. These workloads require immense computing power, significantly straining data centers’ energy consumption and cooling infrastructure.
Traditional air-cooling systems, though widely used, are approaching their capacity limitations. This is where liquid cooling comes into play. By using specialized fluids to transfer heat away from components, liquid cooling systems offer several advantages:
- Enhanced Energy Efficiency: Liquid cooling reduces the amount of energy needed to operate data centers, leading to substantial cost savings. Nomura estimates that liquid cooling can save between 10% and 15% in capital expenditure compared to air-cooling systems.
- Improved Performance: Liquid cooling enables data centers to operate at higher temperatures, allowing for denser server deployments and ultimately boosting processing power.
- Reduced Noise: Liquid cooling systems are significantly quieter than air-cooling systems, creating a more comfortable and quieter environment.
These benefits make liquid cooling an attractive option for tech giants like Nvidia, who are pushing the boundaries of AI performance. Nvidia’s next-generation AI graphics processor, GB200, slated for release later this year, is expected to heavily rely on liquid cooling. Nomura forecasts a substantial increase in liquid cooling penetration rate in Nvidia’s AI servers in the coming years, rising from 8% in 2024 to 43% in 2025, and 47% in 2026.
Asian Companies Capitalize on the Liquid Cooling Trend
The growing demand for liquid cooling solutions has created a lucrative market, attracting investments from various companies worldwide. Analysts at Jefferies have identified four Asian companies as key beneficiaries of this trend:
AVC
AVC, a Taiwanese manufacturer, is a prominent player in the cold plate market. Cold plates are critical components in liquid cooling systems, transferring heat away from devices and dissipating it within the cooling system. Jefferies estimates AVC to hold at least 50% market share in cold plate orders for Nvidia’s G200 from leading cloud service providers, showcasing its dominance in the sector. The firm has also assigned a price target of 743 Taiwan dollars ($23.20) for AVC’s stock, implying a potential 30% upside.
Auras
Auras, another Taiwanese company, also supplies cold plates to the industry. It plays a significant role in supporting both Super Micro Computer, a major beneficiary of the AI boom, and Quanta’s CDU for Meta. CDUs (Coolant Distribution Units) are crucial for delivering and managing the coolant throughout the system. Jefferies has set a price target of 797 Taiwan dollars for Auras’s stock, representing a 25% upside potential.
Delta
Delta, a Taiwanese firm, is a major manufacturer of liquid cooling solutions. Jefferies predicts Delta will gain significant market share in the liquid cooling segment for tech giants like Microsoft, Meta, and Amazon Web Services. With a price target of 490 Taiwan dollars, Delta’s stock boasts a predicted 25% upside.
Nidec
Nidec, a Japanese company, is a prominent provider of CDUs to Super Micro Computer. Jefferies recognizes Nidec’s aggressive drive in this business, which is a major driver of growth. The firm has assigned a price target of 9,000 Japanese yen ($62.6) for Nidec’s stock, representing a potential 53% upside.
Conclusion: A Vital Component in the AI Evolution
The shift towards liquid cooling is becoming a crucial factor in supporting the growth of the AI industry. As AI workloads continue to increase exponentially, the demand for efficient and cost-effective cooling solutions will only grow. Liquid cooling technology offers significant advantages, making it an essential component in the foundation of AI’s evolution. Asian companies are emerging as key players in this market, capitalizing on the surging demand for these advanced cooling systems. The trend towards liquid cooling is shaping the future of AI infrastructure, offering significant implications for both tech giants and investors alike.
