Core Viewpoint - Immersion liquid cooling is a promising solution for high power density scenarios in data centers, with potential market opportunities driven by increasing demand for cooling solutions due to rising power densities from AI and 5G applications [1][2][4][6]. Group 1: Liquid Cooling Technology - Liquid cooling technology is essential for addressing heat dissipation challenges in data centers, especially with the increasing power density of AI servers, which can reach 2000-3000W compared to traditional servers at 300W-1000W [2]. - The current mainstream cooling solution is cold plate liquid cooling, which primarily uses water and ethylene glycol as cooling mediums, accounting for approximately 70% of the liquid cooling market [3]. - Two types of cold plate liquid cooling exist: single-phase (no phase change) and two-phase (with phase change), with the latter offering higher cooling efficiency suitable for higher power densities [3]. Group 2: Immersion Liquid Cooling - Immersion liquid cooling is more efficient than traditional cold plate systems, utilizing non-conductive cooling liquids to dissipate heat through convection and phase change [4]. - Single-phase immersion cooling is currently favored due to lower deployment costs and reduced risk of coolant spillage, while two-phase immersion cooling, although more efficient, faces challenges in cost and technology maturity [4]. Group 3: Market Potential and Demand - The International Energy Agency (IEA) predicts that global data center installed capacity will reach 114.3 GW by 2025, with annual additions ranging from 9 GW to 24 GW between 2024 and 2030, leading to a potential demand for 40,000 tons of fluorinated liquids [6]. - The estimated market space for immersion cooling solutions, based on a fluorinated liquid price of 250,000 CNY per ton, is approximately 10 billion CNY [6]. Group 4: Key Players and Recommendations - Companies in the fluorinated liquid space, such as Dongyangguang (600673.SH), Juhua Co. (600160.SH), and Yonghe Co. (605020.SH), are recommended for investment due to the growth potential in the cooling medium market [7][8].
