Core Viewpoint - The article emphasizes the rapid growth of global computing power demand driven by advancements in artificial intelligence, cloud computing, and high-performance computing, leading to unprecedented cooling challenges for data centers. Liquid cooling technology is evolving from an optional solution to a necessary one due to its energy efficiency, low power consumption, and noise reduction advantages, especially in light of tightening national PUE (Power Usage Effectiveness) requirements. The article outlines the evolution of liquid cooling technology, market landscape, and future trends, predicting that the global liquid cooling market will exceed 100 billion yuan by 2026, marking the beginning of a liquid cooling revolution driven by technology, policy, and industry collaboration [2]. Group 1: Liquid Cooling Technology - Liquid cooling technology is essential for addressing the cooling pressures of data centers. It utilizes liquid to dissipate heat from components, leveraging the high thermal conductivity and heat capacity of liquids compared to air, resulting in lower energy consumption, higher cooling efficiency, and reduced noise [6][13]. - The core advantages of liquid cooling include low energy consumption, high cooling capacity (4-9 times that of air cooling), low noise levels, and lower total cost of ownership (TCO), with PUE values potentially dropping below 1.2 [13][26]. - The rapid increase in chip power density necessitates the adoption of liquid cooling solutions, as traditional air cooling struggles to meet the demands of next-generation architectures like NVIDIA's Rubin, which anticipates power densities reaching up to 600 kW [14][18]. Group 2: Market Trends and Future Outlook - The liquid cooling market is expected to surpass 100 billion yuan by 2026, driven by technological advancements, policy support, and collaboration across the supply chain [2]. - The evolution of liquid cooling technology is characterized by the emergence of microchannel cold plates and phase change cooling plates, which enhance efficiency and customization [2][14]. - The article highlights the increasing importance of liquid cooling in meeting national PUE requirements, with policies pushing for lower PUE values, thereby promoting the adoption of energy-efficient technologies [22][25]. Group 3: Industry Applications and Solutions - Liquid cooling solutions are categorized into direct contact and indirect contact types, with single-phase immersion cooling being the primary development direction due to its high efficiency and energy savings [30][47]. - Single-phase cold plate cooling is expected to remain the mainstream solution for a considerable time due to its compatibility with existing infrastructure and lower retrofit costs [37]. - Immersion cooling offers high energy efficiency (PUE < 1.13) and supports high-density deployments, although it presents challenges in product design and maintenance [48][49].

Group 1 - Liquid cooling technology is essential for addressing the heat dissipation pressure in data centers, offering advantages such as low energy consumption, high heat dissipation, low noise, and low total cost of ownership (TCO) [1][2] - The value of liquid cooling systems is expected to grow significantly alongside chip upgrades, with a projected increase of over 20% for rack liquid cooling modules in GB300-GB200 servers [1][2] - The market for ASIC liquid cooling systems is estimated to reach 35.3 billion yuan by 2026, while the market for NVIDIA liquid cooling systems is projected to reach 69.7 billion yuan [1][2] Group 2 - The domestic supply chain is accelerating its entry into the liquid cooling market, with NVIDIA opening its supplier list to allow more flexibility in supply chain composition [2] - The Rubin architecture requires new liquid cooling solutions due to its high thermal design power (TDP) of 2300W, necessitating alternatives to single-phase cooling plates [2] - Two viable solutions for the Rubin architecture include phase change cooling plates and microchannel plates, with the latter likely becoming the preferred option as power requirements increase [2] Group 3 - The demand for AI server computing power is rapidly increasing, driving the penetration rate of liquid cooling solutions, and leading to an explosive demand for efficient and energy-saving heat exchange solutions in data centers [3] - Companies to watch in this sector include Yingweike, Shenling Environment, Gaolan Co., Hongsheng Co., Zhongke Shuguang, and Jieban Technology [3]

Core Viewpoint - The current mainstream solution for liquid cooling is the cold plate system, while immersion cooling is expected to become a future development direction. The maturity of domestic liquid cooling systems is increasing, and domestic supply chains are likely to enter the NVIDIA ecosystem directly as demand for AI server computing power surges, driving the penetration rate of liquid cooling solutions [1][2]. Group 1: Liquid Cooling Technology - Liquid cooling technology is essential for addressing the heat dissipation pressure in data centers, offering advantages such as low energy consumption, high heat dissipation, low noise, and low total cost of ownership (TCO). It can also reduce the Power Usage Effectiveness (PUE) of data centers, meeting national requirements [1]. - As chip iterations increase power density, the heat dissipation requirements for corresponding chips are growing, making traditional air cooling insufficient and necessitating the introduction of liquid cooling solutions. Currently, cold plate systems dominate the market, while immersion cooling is anticipated to be a future trend [1]. - The liquid cooling system consists of an outdoor side (primary side) and a data center side (secondary side), with the primary side accounting for approximately 30% of the value, including chillers and circulation pipelines, while the secondary side accounts for about 70%, with core components such as CDU, manifold, quick connectors, and water pumps [1]. Group 2: Liquid Cooling Industry - The value of liquid cooling is expected to increase alongside chip upgrades. For example, the value of rack liquid cooling modules is projected to grow by over 20% with the transition to GB300-GB200 servers. By 2026, the market for ASIC liquid cooling systems is estimated to reach 35.3 billion yuan, while the market for NVIDIA liquid cooling systems is expected to reach 69.7 billion yuan [2]. - Domestic supply chains are accelerating their entry into the liquid cooling market. NVIDIA has opened its supplier list, allowing manufacturers to choose their supply chain components independently. This shift from a single certified CDU supplier to multiple suppliers enables domestic chains to indirectly enter the market. As domestic liquid cooling systems mature and end-user CSPs focus more on cost-performance ratios, domestic suppliers are likely to enter NVIDIA's ecosystem directly [2]. Group 3: Rubin Architecture Outlook - Single-phase cold plates are unsuitable for the Rubin architecture due to its thermal design power (TDP) of 2300W and a total cabinet power of approximately 200KW, exceeding the design limit of single-phase cold plates at 150KW per cabinet. Therefore, new liquid cooling solutions must be introduced [3]. - One feasible solution is the phase change cold plate, which utilizes the phase change of a liquid working fluid to absorb heat efficiently, suitable for scenarios exceeding 300KW per cabinet. Another option is the microchannel cold plate (MLCP), which features densely packed micro-scale cooling liquid channels, potentially becoming the preferred choice for the Rubin architecture as future iterations may require even higher power capacities [3].
