AI Liquid Cooling Becomes Mandatory Infrastructure Industry Status and Outlook
Driven by surging GPU power consumption for next-gen AI servers, traditional air cooling has hit physical heat dissipation limits, making liquid cooling a mandatory infrastructure for high-power AI computing. NVIDIA’s Rubin platform, featuring 100% full liquid cooling and a fan-free design, marks a pivotal industry inflection point. As the overall solution carrier for modern data centers, the data center fluid management system underpins the structural upgrade of AI heat dissipation, bringing definite long-term growth while the market presents a typical contradiction: industry demand consensus is fully established, yet early valuation premiums have created obvious structural differentiation across the supply chain.
New-generation AI hardware brings extreme cabinet heat load, with a single GB300 chip reaching 1400W and a full cabinet exceeding 130kW, far beyond the 30–40kW heat dissipation limit of traditional air cooling. To adapt to high-power computing scenarios, modular liquid cooling CDU has become the core standardized equipment for AI data centers. Cold-plate and immersion liquid cooling are the two mainstream technical routes in the market. The 2026 launch of NVIDIA’s Rubin architecture officially upgrades liquid cooling from an optional accessory to a factory standard configuration for all new AI servers.
A complete liquid cooling system requires the precise coordination of multiple core components. As the key fluid distribution component of the entire system, the liquid cooling manifold undertakes the transmission and shunting of cooling fluid, ensuring balanced and efficient heat dissipation of the entire cabinet. With the large-scale iteration of high-power AI servers, the overall matching capability of liquid cooling systems has become a core indicator of data center operational efficiency.
The liquid cooling industry chain presents obvious hierarchical differentiation in technical barriers and valuation logic. Downstream system integration and midstream cold plate links have sufficient production capacity and full market pricing. The upgraded energy saving liquid cooling CDU further reduces data center operating costs, adapting to the industry’s dual demands of high heat dissipation efficiency and low energy consumption, and has become an important competitive advantage for mainstream equipment manufacturers.
Upstream advanced thermal materials are the highest-elasticity segment of the industry. Traditional copper and aluminum cold plates can no longer support the ultra-high power consumption of Rubin-platform GPUs. Targeting extreme computing scenarios, liquid cooling CDU for high heat load solves the heat dissipation pain point of next-gen AI servers. Diamond thermal materials, with five times the thermal conductivity of copper, have become the optimal solution for high-end heat dissipation, and domestic mass production has achieved a key industrial breakthrough.
The booming construction of AI data centers has driven a rapid surge in market demand for liquid cooling equipment. Standardized and scalable equipment supply has become an industry rigid demand, and liquid cooling CDU bulk supply services have been widely adopted by cloud vendors and IDC operators. The A-share liquid cooling sector shows a structural split: high-valued leading companies have certification advantages but limited short-term earnings release, while second-tier manufacturers have prominent valuation upside.
As the core standalone control unit of the liquid cooling system, the liquid CDU realizes precise closed-loop control of coolant temperature, flow and pressure, which directly determines the operational stability of high-power AI cabinets. 2026 will be a critical verification year for the industry. Q2 financial reports will verify order growth, and Q3 Rubin platform mass production will trigger comprehensive volume growth across the entire liquid cooling chain.
Industry analysts pointed out that AI liquid cooling is a deterministic long-term track driven by hardware iteration, rather than short-term thematic speculation. Serving as the professional supporting equipment for modern computing facilities,data center coolant CDU matches the iterative upgrade of high-power AI servers. The current market has fully priced the long-term logic of leading tracks, and future opportunities will focus on undervalued midstream and upstream links with performance fulfillment capabilities. Advanced thermal materials and standardized liquid cooling equipment will usher in continuous profit release as new AI platforms scale up.
