Summary of Liquid Cooling Market Update Industry Overview - The global liquid cooling market is experiencing rapid growth, with an expected annual growth rate of 20%-25% over the next 3-5 years. The market size for the first three quarters of 2024-2025 is projected to reach approximately $6-7 billion, with North America holding the largest share at 50%-55% [1][2][20]. Key Insights and Arguments - **Market Dynamics**: North American data centers are adopting alternative energy solutions such as renewable energy, battery energy storage systems (BESS), and distributed power generation to address power supply bottlenecks, although these solutions are costly [1][5]. In contrast, domestic manufacturers in China are circumventing chip restrictions by procuring previous-generation GPU chips and utilizing Southeast Asian data centers [1][5]. - **Cooling System Design**: High-power GPU systems in data centers typically employ N+N or 3+3+1 redundancy in power supply systems and N+1 redundancy in thermal management systems. Key components like circulation pumps in cold plate liquid cooling systems also utilize N+1 redundancy [1][6][7]. - **AI Cluster Operations**: In domestic AI cluster operations, both air cooling and liquid cooling coexist, with H100 liquid-cooled cabinets generally using a 30% air cooling and 70% liquid cooling configuration. Single-chip power consumption does not exceed 1,000 watts, primarily relying on unidirectional liquid cooling plates [1][8]. - **Cooling Technology Selection**: The choice between cold plate and silent liquid cooling technologies is based on the thermal flow density of GPU chips. Air cooling is recommended for under 1 kW, unidirectional liquid cooling plates for 1-2 kW, and bidirectional liquid cooling plates for over 2 kW. Future Ultra series may require a shift to bidirectional phase change solutions [1][8]. - **Market Share**: In North America, the company Viant Technology ranks among the top three in the liquid cooling market, holding a market share of 20%-25%. Their product line includes both air and liquid cooling systems, providing comprehensive solutions for data centers [2][20]. Additional Important Points - **Challenges in Silent Liquid Cooling**: Silent liquid cooling systems face high costs, maintenance difficulties, and large footprint issues, making widespread adoption challenging in the short term. However, significant growth in GPU chip capacity over the next 3-5 years may drive some high-density applications to transition to silent liquid cooling [3][10]. - **Corrosion Prevention**: To combat electrochemical corrosion in liquid cooling systems, deionized water or a solution containing 25%-30% propylene glycol is commonly used, with corrosion inhibitors added to enhance resistance [13][14]. - **Future Trends**: The development of liquid cooling media is shifting from unidirectional to bidirectional systems, with the introduction of microchannel technology. New refrigerants like electronic fluorinated liquids may replace traditional water-based coolants in the future [12][15][16]. - **Market Competition**: The refrigerant market is witnessing significant demand growth, particularly in liquid cooling media. North American clients primarily use refrigerants produced by European and American manufacturers, while domestic companies like Juhua and Dongyangguang are also producing refrigerants for local data centers [18][19]. - **Integration vs. Decoupled Delivery**: Integrated delivery systems provide a simplified deployment process, while decoupled delivery offers greater flexibility for future expansions. Each method has its advantages depending on specific user needs [21][23]. This summary encapsulates the key points from the liquid cooling market update, highlighting the industry's growth, technological advancements, and competitive landscape.
