Sou Hu Cai Jing·2025-08-30 09:37Core Viewpoint - The liquid cooling sector is poised to become a core investment direction in the AI computing revolution, with increasing penetration rates and a shift from speculative trading to fundamental support [4][6][10]. Group 1: Market Dynamics - In August, the AI market expansion spread from optical modules and PCBs to server power supplies and liquid cooling [1]. - Companies like Invec, Oulu Tong, and Megmeet have seen their stock prices reach historical highs, indicating a growing interest in the liquid cooling sector [2]. - The liquid cooling concept has been developing for nearly two years, but the actual market implementation has been slow [5][6]. Group 2: Technological Advancements - The demand for liquid cooling technology is becoming urgent with the release of NVIDIA's Blackwell series chips, which require advanced cooling solutions [8][10]. - The transition from air cooling to liquid cooling is driven by the increasing power requirements of GPUs, with the B200 and B300 chips necessitating liquid cooling solutions [7][8]. - The penetration rate of liquid cooling in AI data centers is expected to rise significantly, from 14% in 2024 to 33% in 2025, as major cloud service providers upgrade their infrastructure [12]. Group 3: Investment Opportunities - The liquid cooling market is projected to reach 100 billion RMB by 2026, driven by the increasing demand for AI servers and the expansion of liquid cooling solutions [15]. - Companies in the liquid cooling supply chain, such as Invec, have seen substantial stock price increases, with Invec's stock rising nearly 98% in August alone [17]. - The liquid cooling sector is expected to replicate the success of the optical module and PCB markets, with potential for significant growth and investment opportunities [20][27]. Group 4: Competitive Landscape - The liquid cooling industry can be divided into two categories: system integrators like Invec and manufacturers focusing on individual components [28]. - The entry of domestic manufacturers into the global liquid cooling supply chain is anticipated, similar to the previous trends seen in the PCB market [22][24]. - The high entry barriers in the liquid cooling sector are primarily due to the need for advanced system integration capabilities, which many manufacturers currently lack [32][35].
