Liquid Cooling CDU Market Expands Rapidly Driven by AI Computing and Strict PUE Policies
Liquid cooling CDU serves as the thermal core of computing infrastructure, enjoying dual growth dividends from booming AI power demand and tightened PUE supervision. The global market shows an obvious dual competition pattern: Western established manufacturers including Vertiv and Schneider Electric dominate international business, while Chinese local brands such as Envicool and Gaolan develop rapidly amid domestic substitution. This industry report analyzes market scale, competitive landscape, industrial chain and technical trends around systematic data center thermal management.
Driven by high-power AI chips that break the heat limit of air cooling, the global CDU market maintains robust double-digit growth, and 2026 is viewed as the turning point for mass liquid cooling industrialization. Core competitiveness lies in high-precision leakage detection, nano thermal conductive materials and deep cooperation with GPU giants, which guarantee stable operation of the complete closed-loop liquid cooling circulation loop.
As the central control hub of liquid cooling systems, CDU distributes coolant evenly and transfers heat through heat exchange, accounting for a key proportion of cold-plate cooling system cost. Accurate flow and temperature regulation are realized via mature balancing equipment named liquid cooling flow balance unit, supporting both new data center construction and legacy facility renovation.
The global CDU market has moderate concentration yet fierce competition. Tier 1 overseas manufacturers own mature global sales networks and rich thermal management experience, launching high-performance products certified by top GPU and cloud vendors as premium high efficiency CDU for data center.

Specialized suppliers like CoolIT, Boyd and nVent focus on segmented liquid cooling technical routes, delivering steady cabinet-level heat dissipation matched with standardized rack cooling scenarios for telecom and internet computing parks.
Chinese regional competitors speed up market expansion with self-developed vacuum liquid cooling technology and full domestic component supply chains. Integrated manufacturing cuts overall project costs and serves local large cloud operators with flexible expandable modular liquid cooling CDU.
Liquid-to-liquid CDU boasts the top heat dissipation performance among all categories, applicable to super-large HPC and AI computing hubs. Optimized heat exchange structures of professional liquid liquid cooling CDU support ultra-high rack power density and long-term stable operation for high-load GPU clusters.
China’s digital infrastructure policies fuel domestic liquid cooling industry upgrading. Local enterprises lift the self-sufficiency rate of upstream core components and apply low-carbon manufacturing techniques to cut energy consumption, forming a reliable data center PUE reduction solution to meet strict global energy efficiency standards.
