Investment Rating - Investment recommendation: Outperform the market (maintained) [6] Core Viewpoints - The penetration rate of liquid cooling in data centers is expected to increase significantly due to the accelerated shipment of new generation high-performance computing chips, leading to a surge in orders for liquid cooling infrastructure suppliers and entering a phase of rapid performance growth [3][12] - The liquid cooling infrastructure market is projected to grow rapidly, with the domestic market expected to expand from approximately 1.63 billion yuan in 2024 to 13.22 billion yuan by 2027 [39][41] Summary by Sections 1. Liquid Cooling as an Important Industry Trend - Traditional air cooling is inadequate for high power density data centers, making liquid cooling a crucial trend due to its high specific heat capacity, thermal conductivity, low noise, and compact size [8][15] - The current penetration rate of liquid cooling in data centers is low, estimated at around 5% in China, but is expected to rise to 30-40% in the next 3-5 years [10][27] 2. Market Growth Potential - The domestic data center total power is projected to grow from 35.5 GW in 2024 to 68.8 GW by 2027, with a compound annual growth rate (CAGR) of 37% for new data center power [36][38] - The global liquid cooling infrastructure market is expected to grow from approximately 11.08 billion yuan in 2024 to 26.34 billion yuan by 2027, driven by the increasing demand for high-performance GPUs [49][51] 3. Investment Recommendations - Focus on leading domestic companies with comprehensive product lines and rich customer resources, such as Yingweike, Shunling Environment, and Tongfei Co., which are well-positioned to benefit from the growth in liquid cooling technology [12][52]
