Summary of Liquid Cooling Industry Report Industry Overview - The report focuses on the liquid cooling industry, particularly in data centers, driven by the increasing demand for efficient cooling solutions due to high power density and thermal flow density requirements of modern chips [1][2][3]. Key Insights and Arguments - **Liquid Cooling Demand**: The demand for liquid cooling systems in data centers is expected to grow significantly, especially with the rise of AI data centers, which are projected to reach approximately 7GW by 2024 and continue to grow rapidly through 2028 [8]. - **Cooling Technologies**: Two main types of liquid cooling solutions are currently used in data centers: cold plate and silent cooling. Cold plate systems can be further divided into single-phase and multi-phase systems, while silent cooling includes oil-based and fluorinated liquids [4][7]. - **Chip Cooling Requirements**: NVIDIA's new generation of chips, such as the Ruby series, has increased power requirements, necessitating more efficient cooling solutions like phase change liquid cooling [5]. - **Energy Efficiency Management**: Data center energy efficiency management is becoming more refined, moving from chip-level to cabinet integration, with a focus on direct cooling solutions for high-heat areas [6]. Material Insights - **Cooling Fluids**: Various cooling fluids are discussed, including synthetic hydrocarbons and organic silicone oils, which have advantages such as low impurity content and good oxidation resistance, but also drawbacks like low flash points [9][10]. - **Fluorinated Liquids**: Fluorinated liquids provide excellent cooling performance with uniform temperature distribution but are costly and primarily produced by 3M, which plans to exit the market by the end of 2025 [12][16]. - **Environmental Concerns**: PFAS substances pose significant environmental hazards, prompting the search for alternatives like perfluoropolyether (PFPE), which is more degradable but less stable than perfluoramines [17][18]. Market Dynamics - **3M's Market Exit**: The anticipated exit of 3M from the fluorinated liquid market is expected to create opportunities for domestic companies to fill the gap, potentially leading to lower prices for cooling solutions [16][21]. - **Production and Cost Trends**: The price of perfluorinated compounds is currently around 600,000 to 700,000 yuan per ton, significantly higher than the 300,000 to 400,000 yuan per ton range from 2019 to 2021. Future production capacity improvements could lower prices back to previous levels [16]. Additional Important Content - **Key Players**: Notable companies in the organic silicone production space include Dow, Wacker, and domestic firms like Runhe Materials, which are innovating in the field [14]. - **Future Developments**: The report highlights ongoing research and development in alternative cooling solutions, including the use of hydrogen fluoride ethers in semiconductor cleaning and cooling applications [20]. This comprehensive overview captures the essential elements of the liquid cooling industry as discussed in the report, emphasizing the technological advancements, market dynamics, and environmental considerations shaping the future of data center cooling solutions.
