NVIDIA Rubin Platform Mandates Full Liquid Cooling Ushering in New Industry Prosperity Cycle

NVIDIA’s new Rubin platform officially mandates full liquid cooling as the standard for next-gen AI data centers. Three core rules — fan-free racks, 45℃ warm-water cooling and rigid metal pipelines — fully upgrade AIDC thermal systems. This standard raises new requirements for cold plates, connectors and CDUs, triggering explosive upstream orders, while optical module liquid cooling brings new incremental growth to the industry.

Compliant with Rubin’s strict specifications, the high-precision modular liquid cooling CDU supports plug-and-play modular deployment, delivering accurate flow and pressure control for high-density AI rack cooling.

Featuring fan-free and 45℃ constant-temperature design, the advanced liquid cooling data center eliminates air cooling limitations, improving power density and reducing operational and maintenance costs.

Unifying scattered cooling architectures, systematic data center thermal management optimizes full-link heat dissipation, effectively lowering PUE and stabilizing operation of high-power AI clusters.

Built for 45℃ medium-temperature circulation, the optimized high efficiency liquid cooling infrastructure adopts upgraded cold plates, high-temperature seals and high-power pumps, phasing out outdated low-temperature-resistant equipment and boosting overall cooling efficiency.

As the core loop control unit, intelligent cdu liquid cooling dynamically adjusts coolant status, prevents rack downtime caused by thermal failure, and dominates 25%–26% of total system costs.

Optimized for high-voltage AI cabinets, professional chilldyne liquid cooling ensures stable high-temperature and high-pressure heat exchange, accelerating domestic substitution of high-end cooling pump components.

Fully replacing traditional fan cooling, dedicated server cooling liquid undertakes all heat dissipation for GPUs and high-speed optical modules, becoming the sole cooling solution for fan-free Rubin racks.

Equipped with rigid pipelines, blind-plug connectors and precise CDU regulation, the reliable data center liquid cooling system avoids high-pressure leakage, improves cabinet space utilization and supports large-scale AI infrastructure deployment.

Rubin unifies full liquid cooling standards and completely phases out air cooling for high-end AI cabinets. Its fan-free design, 45℃ constant-temperature cooling and rigid pipeline scheme drive rigid growth of liquid cooling components, with single-rack cooling value rising 17% versus GB300 and 34% versus air-cooled models. Extended upstream order cycles guarantee strong annual performance certainty.

Microchannel cold plates, blind-plug connectors and CDU pumps occupy nearly 90% of system costs. Upgraded 50–100μm microchannel cold plates require high-barrier vacuum brazing, creating tight capacity supply. Certified leading manufacturers maintain full-capacity production. Hongfuhan delivers mass Rubin cold plate orders, while Chengtian Weiye expands production and verifies overseas projects.

Blind-plug connectors and stainless steel bellows are the fastest-growing segment, with single-rack usage doubled and 2026 growth exceeding 72%. Traditional hose connectors are eliminated, replaced by high-reliability PBMC blind-plug products. Domestic firms including AVIC Optoelectronics achieve rapid technological iteration. Standardized liquid cooling also endows pipelines and connectors with sustainable consumable attributes.

CDU and high-pressure DC cooling pumps are core system hubs. The popularization of 800V high-voltage cabinets accelerates pump domestic substitution. Leading system integrators such as Invicool and Shenling Environment deliver certified CDU solutions, while Feilong Shares and other component suppliers realize batch supply with mature automotive thermal management technologies. System integration capability constitutes the core industry barrier.

Optical module liquid cooling emerges as the industry’s second growth curve. As 1.6T/3.2T optical modules exceed 40W power consumption, traditional cooling fails to meet demands. The related market will reach USD 1 billion in 2026 and USD 6.3 billion by 2030, with a 58%+ CAGR. The emerging track features low monopoly and high growth potential for precision component manufacturers.

Driven by Rubin standards, the liquid cooling industry expands rapidly. China’s market scale will hit CNY 94.2 billion in 2026 and 147.8 billion in 2027. Global AIDC liquid cooling market will surpass USD 21.8 billion in 2027 and 50.5 billion by 2030. High-end AI cabinet liquid cooling penetration will rise from 35% to over 70% within two years, driven by high chip power, optimized warm-water cooling and low-PUE policies.

Short-term opportunities focus on cold plates, connectors and metal pipelines with fast order release. Mid-to-long-term growth lies in CDU system integrators and high-voltage pump manufacturers via domestic substitution and overseas expansion. Optical module liquid cooling and cross-industry thermal management enterprises also bring prominent incremental elasticity.

Main risks include low-end capacity surplus, concentrated client procurement volatility, M&A goodwill impairment and iterative impact of immersion cooling technology.

To conclude, NVIDIA Rubin’s full liquid cooling specification triggers a long-term industrial upgrade of AI thermal management. The sector is no longer a short-term concept but a rigid growth track supported by chip iteration, unified technical standards and energy-saving policies. Core enterprises with proprietary technology, stable orders and system integration capabilities will dominate future market growth.
