2026-03-19 02:39Summary of AIDC Liquid Cooling Update - GTC Conference 2026 Industry Overview - The report focuses on the liquid cooling industry, particularly advancements in cooling technologies and supply chain dynamics related to data center equipment, specifically the new Rubin series and its components [1][2]. Key Points and Arguments Product Advancements - The Rubin series has increased power consumption to 200-220 kW and comes standard with full liquid cooling, raising the value of a single cabinet cold plate from $25,000 (GB300) to $52,000 [1]. - The design shift from small to large cold plates, incorporating 150-micron microchannel technology, has increased the value of a single cold plate from $200 to $800 [1]. - The price of Quick Disconnect (QD) connectors has risen to $80-90 due to increased flow requirements, with total cabinet value for QD connectors estimated at $11,000 to $12,000 [1][4]. - The CDU (Cooling Distribution Unit) specifications have increased from 1.3 MW to 2.3 MW, with prices rising to $450,000, leading to a 50% increase in per-cabinet value [1]. Supply Chain Dynamics - NVIDIA may tighten AVL (Approved Vendor List) certifications and standardize liquid cooling architectures, solidifying the positions of Taiwanese and European suppliers while creating opportunities for mainland Chinese companies to shift towards OEM production [1][3]. - Current suppliers' positions are stable, with no significant changes in the supplier landscape despite attempts by new entrants to join NVIDIA's supply chain [2][3]. Component Value Changes - The Rubin series has significantly improved power consumption and liquid cooling solutions compared to the GB300 series, with specific value changes: - Cold plates: Total value per cabinet increased to approximately $52,000 due to the new design and additional components [3]. - QD connectors: The number required per cabinet decreased from 270 to 140, but the price per pair increased, leading to a total value of $11,000 to $12,000 per cabinet [4]. - Manifold value remains stable at around $20,000 per cabinet [4]. Cooling Technology Trends - The 45-degree warm water technology will not completely replace chillers, as data centers still require backup chillers for extreme weather conditions [5]. - The trend towards magnetic levitation compressors is clear, as they significantly reduce PUE (Power Usage Effectiveness) and have minimal mechanical wear, making them suitable for modern data center operations [5]. Investment Opportunities Recommended Companies 1. Cabinet External (Primary Side): - Focus on companies like Shenli Environment for chiller production, Lianchuang Co. for compressor parts, and Xue Ren Co. for magnetic levitation compressors [6]. 2. CDU: - Recommended companies include Shenli Environment and Invec, which have strong capabilities in data center design and delivery, appealing to non-NVIDIA CSP clients [6]. 3. Cabinet Internal (Secondary Side): - Starry Technology is highlighted as a leading OEM for QD connectors, benefiting from expected order doubling from Danfoss in 2026, with potential expansion into other core products [6]. Additional Important Insights - The shift in supply chain dynamics and the tightening of NVIDIA's certification process may create significant OEM opportunities for mainland Chinese companies, particularly those with production capabilities [3]. - The overall trend in the liquid cooling industry indicates a move towards higher efficiency and integration of advanced technologies, which could reshape competitive dynamics in the sector [5].
