Guoxin Securities·2025-09-29 05:26Investment Rating - The report rates the industry as "Outperform" [2] Core Viewpoints - The rise in computing power density necessitates liquid cooling as the primary heat dissipation technology for intelligent computing centers. Liquid cooling offers advantages over air cooling, including faster temperature transfer, higher heat removal capacity, lower noise, energy savings, and space efficiency. The global trend towards stricter PUE assessments is expected to drive the penetration of liquid cooling technology [7][11][26] - The global market for liquid cooling in data centers is projected to exceed $10 billion by 2026, driven by the increasing power of AI chips and the growing density of server cabinets. The North American market alone is expected to reach $10 billion, with significant contributions from companies like NVIDIA [8][93] - Domestic liquid cooling market in China is expected to reach approximately 11.3 billion yuan in 2026, with a further increase to 23.8 billion yuan in 2027, as operators gradually adopt liquid cooling solutions [8][86] Summary by Sections 1. Computing Power Density and Liquid Cooling Technology - The increasing power density of AI chips is pushing the limits of traditional air cooling methods, making liquid cooling essential for managing heat in intelligent computing centers. Liquid cooling systems are categorized into room-side and ICT device-side architectures, with cold plate technology currently being the most widely adopted [7][10][11] 2. Accelerating Liquid Cooling Application and Market Size - The cooling system costs account for over 20% of the total data center infrastructure costs. Liquid cooling is expected to further increase this investment share. The report estimates that by 2026, the liquid cooling market in China will surpass that of air cooling, with a projected market size of 21.8 billion yuan [80][81][86] 3. Liquid Cooling Industry Chain Analysis - The liquid cooling industry chain consists of upstream components (liquid cooling parts), midstream system integrators, and downstream customers (data center service providers, operators, and internet companies). The report emphasizes the importance of system-level understanding for specialized temperature control manufacturers to benefit from industry growth [97][101]
