Booming trillion-parameter AI model computing demands have sharply lifted the power density of intelligent computing centers, with NVIDIA Blackwell architecture cabinet power consumption far exceeding the limits of traditional air cooling. Full liquid cooling has become the standard solution for high-density data centers, where precise fluid distribution and zero-leakage operation are critical. As the core fluid distribution hub linking CDU and server cold plates, liquid cooling CDU manifold ensures balanced coolant delivery for server nodes and stabilizes overall cluster heat dissipation performance.

The rapid iteration of high-power AI chips has completely rewritten data center thermal management standards. H3C launched the high-density full liquid cooling complete cabinet S90000 at the NAVIGATE 2026 Summit, delivering ultra-high core density and pushing data center PUE below 1.05 through innovative high-density power supply and full liquid cooling architecture. NVIDIA also officially defined the Vera Rubin NVL72 platform as the first fully liquid cooling architecture at the 2026 GTC Conference. Leading global computing facilities including GB300 Rubin, Google TPU v7 and Meta Minerva have fully migrated to liquid cooling solutions. As single-chip power consumption surges sharply, traditional air cooling has reached absolute physical limits, making professional liquid CDU cooling system an indispensable foundation for high-density AI computing deployment.

Escalating AI server power density and rigorous PUE reduction requirements have exposed the limitations of traditional air cooling. Though full liquid cooling represents the future of data center thermal management, high costs and complex construction hinder its large-scale rollout. As a viable intermediate solution for legacy upgrades and new high-density deployments, the data center rear door heat exchanger delivers balanced performance, cost efficiency and future-proof capabilities for evolving AI computing workloads.

High performance computing data centers act as vital infrastructure for advanced computing development. Complex tasks from artificial intelligence simulation and gene research bring extreme power and heat loads, creating huge gaps between HPC facilities and traditional computer rooms. Stable operation of intensive computing clusters relies on efficient thermal control, and widely deployed liquid cooled server effectively solves equipment overheating risks.

Traditional air cooling relies on air pressure difference and convection for heat dissipation, which suffices for low-power data center operation. In this scenario, the liquid cooling manifold only acts as an auxiliary component inside precision air conditioners, distributing refrigerant for internal evaporation loops without participating in room-level cooling regulation.

Air cooling solutions dominated early data center thermal management when rack power loads stayed low. Such systems rely on massive air volume and high speed ducts to dissipate heat via thermal convection inside plenum and return air chambers. Air circulates freely through open spaces driven by pressure differences, so early fluid distribution components stayed out of the core cooling loop. The liquid cooling manifold only served as an internal auxiliary part for precision air conditioners, evenly distributing refrigerant to evaporator loops. Hidden inside cooling units, it merely supported internal refrigerant circulation without participating in rack level overall thermal regulation.

Liquid cooling outperforms air cooling in heat transfer efficiency noise control space utilization and power saving. NVIDIA GB200 series adopts full cold plate liquid cooling covering all core chips. Liquid cooling systems split into facility and equipment sides, with cold plate and immersion sharing identical facility loop structures. The air liquid CDU with manifold matches primary and secondary loops to deliver stable coolant distribution via plate heat exchangers inside CDU units.

Rack level liquid cooling systems treat individual server cabinets as independent thermal management units, delivering coolant to server CPUs, GPUs and other high-heat components for efficient heat removal. Consisting of CDU, cold plates, sealed pipelines, heat exchangers and intelligent control systems, these integrated setups effectively boost cooling performance and cut data center power consumption. Professional vendors acting as a trusted liquid cooling CDU solution provider offer standardized and customized system designs to adapt to diverse data center deployment scenarios.

Liquid cooling uses deionized water and fluorinated liquid to build closed heat dissipation loops, split into cold plate immersion and spray types. It cuts PUE below 1.05 and saves over 30% power, supporting racks above 130kW. China’s liquid cooling server market will hit 35.9 billion RMB in 2025 with 72.4% annual growth, and system penetration will rise from 7% to 45% by 2030. Professional liquid cooling CDU manufacturer supplies matched circulation hardware for all mainstream cooling architectures.

Liquid cooling replaces air with liquid media to exchange and carry away heat from server components, maintaining stable and safe operating temperatures for electronic devices. As a foundational thermal control technology, it is categorized into indirect and direct cooling types based on contact modes. Indirect cooling is dominated by cold plate solutions, including single-phase and two-phase structures, while direct cooling covers immersion and spray cooling. Industry data shows cold plate cooling accounts for 91% of current market share, immersion cooling for 8%, and spray cooling for merely 1%. Delivering outstanding advantages in heat dissipation efficiency, energy conservation and space optimization, professional liquid cooling distribution unit equipment empowers modern data centers to achieve greener and more efficient thermal management compared with traditional air cooling systems.
