The “Smart Brain” of Liquid Cooling — 2.6MW Peak Load · PID Precision Control · 3+1 Pump Redundancy
Product Overview
The High-Power In-Row CDU (Coolant Distribution Unit) is the flagship cooling core of Xinke Intelligent’s liquid cooling product line, purpose-built for ultra-large cold plate liquid cooling clusters with a rated load capacity of 2.6MW, comfortably serving ultra-high-density groups such as GB200 NVL72. As the “smart brain” of the liquid cooling system, it provides surging heat exchange power and precise intelligent control, giving massive computing loads stable, accurate and efficient “blood circulation” and leading intelligent computing centers into an era of ultimate energy efficiency.
Integrating Xinke’s proprietary PID dynamic regulation, 3+1 pump redundancy with rotation and 90% computing waste heat recovery, it helps keep whole-room PUE below 1.1; compliant with multiple international certifications including North America and CE, it supports global deployment as the irreplaceable core power engine of cold plate liquid cooling clusters.
Key Features
01 2.6MW Peak Load, Confidently Serving Ultra-Dense Groups: With a rated load capacity of 2.6MW, purpose-built for ultra-large cold plate liquid cooling clusters, it delivers surging heat exchange power for single high-power racks or entire cold plate micro modules, perfectly matching the stringent cooling needs of next-generation AI servers such as GB200 NVL72.
02 PID Dynamic Regulation, Millisecond Precision Cooling: Xinke’s proprietary PID dynamic regulation monitors server load changes in real time, adjusting coolant flow and velocity within milliseconds to maximize cooling margin while minimizing pump energy — significantly reducing data center OPEX.
03 3+1 Pump Redundancy with Rotation, Zero-Downtime Operation: The “3 active + 1 standby” pump circulation system rotates four high-quality pumps to reduce individual wear; the system runs at full speed even when any pump is under maintenance, achieving true zero-downtime operation.
04 90% Waste Heat Recovery, “Compute + Heat” Integration: Deeply integrated waste heat recovery converts up to 90% of computing heat into directly usable 55°C-70°C high-quality hot water for industrial and civil heating, transforming data centers from “energy consumers” into “energy hubs.”
05 PLC Intelligent Control, Expert-Level Diagnostics: PLC-based intelligent control with an expert fault diagnosis system that automatically identifies abnormal conditions in pumps, heat exchangers, piping and electrical components, quickly locating faults with recommended actions.
06 Stainless Quality, Whole-System Monitoring & Safety: Core piping in 304 stainless steel, anti-corrosion and contaminant-free; real-time monitoring of temperature, pressure, flow and differential pressure with optional leak detection and alarm, keeping every operating parameter visible and controllable.
07 Modbus Standard Communication, Unified Monitoring: Supports Modbus RTU/TCP standard protocols for integration with building management and upper-level platforms; optional XINKE SMART for remote O&M and unattended operation.
08 Global Certification, Certain Delivery: Compliant with multiple international certifications including North America and CE for global deployment; backed by a 30,000 m² manufacturing base with 500MW annual capacity, 2-year warranty and 7×24 service response.

Working Principle & System Positioning
Deployed in-row in liquid cooling aisles, the High-Power In-Row CDU serves as the core power hub of cold plate liquid cooling clusters: primary-loop coolant circulates through the server loop driven by the pump group, the plate heat exchanger passes heat to the secondary loop, and outdoor dry coolers, closed cooling towers or integrated cooling stations reject it to the environment; PID control matches load changes in milliseconds and multi-pump rotation keeps circulation uninterrupted; 90% of computing waste heat is converted by the recovery system into 55°C-70°C hot water for “compute + heat” integration. Together with the Rack-Mounted CDU, it forms a multi-level cooling distribution system covering everything from single cabinets to ultra-large clusters.
