Summary of AIDC Power and Liquid Cooling Sector Conference Call Industry Overview - The AIDC industry is expected to see significant opportunities in 800V HVDC and liquid cooling technologies by 2026, driven by factors such as Google's TPU V7 chip power consumption exceeding expectations, the spread of power shortages in North America, and high capital expenditure expectations from leading domestic manufacturers [1][2][6]. Key Insights and Arguments - The liquid cooling market is projected to reach 20-30 billion yuan by 2025 and is expected to explode to over 100 billion yuan in 2026, primarily driven by demand from NV GB300 cabinets, Google ASIC cabinets, and other cloud providers [1][5][7]. - The 800V HVDC technology is anticipated to become mainstream in 2026, offering higher efficiency and lower costs compared to traditional UPS systems. Delta and Vitec have already received orders from Google and Meta [1][19]. - Domestic manufacturers are expected to transition from OEM to system solution providers in the long term, with companies like Invec and Siquan New Materials showing leading advantages [1][9][10]. Market Dynamics - The North American power market is facing challenges due to power shortages, which is driving data centers to adopt off-grid and co-location models. Gas turbines and energy storage systems are emerging as solutions, with companies like Jerry and Doosan Energy receiving orders from North American data centers [4][28]. - The tightening of NV Code is expected to increase the scarcity of manufacturers already connected with NV, enhancing their competitiveness [11]. Investment Opportunities - High-potential investment directions in the AIDC sector include: 1. In-cabinet server power supplies, driven by inflation logic and capacity shortages among leading manufacturers [3]. 2. Changes in power supply architecture from traditional UPS to HVDC, driven by systemic power shortages in North America [5]. 3. Increased overseas spending on computing power and upgrades in chip liquid cooling solutions [5]. Challenges and Opportunities for Chinese Manufacturers - The Chinese liquid cooling industry faces short-term challenges due to dominance by Taiwanese companies, but mergers and acquisitions may enhance competitiveness. In the long term, the industry is expected to evolve towards providing comprehensive system solutions [9][10]. - Invec and Siquan New Materials are positioned to capitalize on these trends, with Invec's market value potential estimated to exceed 100 billion yuan and Siquan New Materials aiming to become a "small Invec" [12]. Future Trends in Liquid Cooling Technology - Liquid cooling technology is expected to continuously evolve, with innovations such as microchannel technology and gold plating to enhance heat dissipation efficiency. New entrants like Red Sea Teda and Quanta are expected to provide more opportunities for domestic supply chains [8]. Magnetic Components Industry - The demand for magnetic components in AI power supply equipment is increasing, with companies like Jincaihua and Keli benefiting from the recovery in new energy vehicles and energy storage [25]. Conclusion - The AIDC power and liquid cooling sectors are poised for significant growth driven by technological advancements and market demands. Key players in the industry are expected to leverage their positions to capture emerging opportunities while navigating challenges posed by competition and market dynamics [1][2][4][5][19].
