Investment Rating - The report maintains an "Outperform" rating for the industry [1] Core Insights - The rapid growth of data centers and the increasing power demands necessitate efficient cooling technologies, with liquid cooling addressing high energy consumption and heat generation issues. By 2024, China's computing centers are expected to consume 166 billion kWh, accounting for 1.68% of the total electricity consumption [2][2] - The main liquid cooling technologies include cold plate and immersion cooling, with cold plate cooling being the most widely used due to its mature technology. Liquid cooling offers multiple advantages such as high heat transfer efficiency, energy savings, and reduced noise [2][2] - The market for cooling liquids is projected to grow significantly, with an estimated demand of approximately 89,000 tons for AI data centers by 2028, alongside 19,000 tons from traditional server installations [2][2] Summary by Sections 1. Main Cooling Paths - Liquid cooling technology is categorized into indirect cooling (mainly cold plate) and direct cooling (including immersion and spray cooling). Cold plate cooling is the most prevalent, while immersion cooling offers higher heat dissipation capabilities but comes with higher operational costs [2][2][2] 2. Water-Based Cooling Liquids - Water-based cooling liquids are primarily used in single-phase cold plate cooling, offering good thermal conductivity and low cost. However, they may pose risks of microbial growth [50][50] 3. Oil-Based Cooling Liquids - Oil-based cooling liquids, including mineral oil and synthetic oil, are mainly applied in single-phase immersion cooling. They are cost-effective and environmentally friendly but have lower thermal conductivity compared to synthetic alternatives [56][56] 4. Market Space Estimation - The liquid cooling market in China is expected to exceed 100 billion yuan by 2027, with a compound annual growth rate of 51.4% from 2019 to 2027 [17][17] 5. Commercialization of Liquid Cooling Technology - The commercialization of liquid cooling technology is increasing, with major IT companies like Alibaba, Baidu, and Tencent implementing successful liquid cooling applications [27][27]

Investment Rating - The report maintains an "Outperform" rating for the fluorochemical industry [5][8]. Core Views - The fluorochemical industry is experiencing a strong performance, with the industry index outperforming major stock indices in August 2025. The fluorochemical index rose by 16.75% compared to the previous month, indicating robust market dynamics [1][15]. - Main refrigerant prices are expected to continue stable growth, driven by limited supply and strong demand. The average prices for R32 and R134a are projected to rise in the coming months [2][22]. - The development of liquid cooling technology is expected to significantly boost the demand for fluorinated liquids and refrigerants, as traditional cooling methods are becoming less effective [4][62]. Summary by Sections 1. Industry Performance - As of August 29, 2025, the fluorochemical index reached 1681.54 points, up 16.75% from the end of July, outperforming the Shenwan Chemical Index by 7.77 percentage points [1][15]. 2. Refrigerant Market Review - The prices of major refrigerants are on an upward trend due to supply constraints. R32 is expected to average 62,000 CNY/ton in September to November, while R134a is projected to average 52,000 CNY/ton [2][22][24]. - Export data shows a mixed performance, with R32 exports increasing by 13% year-on-year, while R22 exports decreased by 34% [35]. 3. Liquid Cooling Demand - The rise of AI technology and increased server power density are driving the shift towards liquid cooling solutions, which are more efficient than traditional air cooling methods. This trend is expected to enhance the demand for fluorinated liquids and refrigerants [4][62][66]. 4. Regulatory Environment - China's commitment to the Montreal Protocol includes significant reductions in HCFCs and HFCs production and usage, which will impact the refrigerant market dynamics positively in the long term [71][74]. 5.
