4U 6KW In-Rack Liquid-to-Air Coolant Distribution Unit (CDU) For Data Center Cooling

4U 6KW In Rack CDU

4U 6KW In-Rack Liquid-to-Air CDU | Liquid Cooling Data Center & IT Systems

This 4U 6KW  Liquid-to-Air Coolant Distribution Unit (CDU) series features a groundbreaking dual-mode cooling architecture, pushing rack-level heat dissipation performance to unprecedented heights. By dynamically balancing air and liquid cooling, the system delivers up to 6KW of maximum heat dissipation density in a compact 4U chassis, several times more efficient than traditional air-cooling solutions.

With a standard 4U height, this product fits seamlessly into any standard data center environment and can efficiently dissipate up to 6KW of heat. It is highly compatible with blockchain mining rigs and AI compute servers, offering exceptional flexibility. The system requires no additional cabinet connections, as it comes with built-in cooling functionality and features redundant power supplies for high availability. The CDU can be easily deployed in existing IDC data centers, integrating effortlessly into existing infrastructures without the need for additional modifications.

This significantly enhances system stability and reduces overall PUE to approximately 1.15, offering a revolutionary improvement in energy efficiency.The CDU saves 33% of rack space, making it suitable for a wide range of applications, from edge computing to supercomputing clusters, and drives a comprehensive transformation in energy efficiency.

FAQ: In-Rack Coolant Distribution Units (CDUs)

1. What is an in-rack CDU and how does it function in data center liquid cooling?

An in-rack Coolant Distribution Unit (CDU) is a compact, localized thermal management system installed directly inside a standard 19-inch server rack or OCP enclosure (typically occupying 4U to 5U of space). It acts as the critical barrier and operational "heart" between two separate cooling loops

2. At what rack power density becomes necessary to deploy an in-rack CDU instead of traditional air cooling?

Data center operators should consider transitioning to an in-rack CDU when individual rack power density surpasses 20 kW to 30 kW.  

Traditional Computer Room Air Conditioner (CRAC) and CRH units struggle to efficiently dissipate heat beyond this threshold due to air's low thermal capacity. With the rapid adoption of next-generation AI, machine learning, and High-Performance Computing (HPC) hardware (such as dense NVIDIA H100/B200 or AMD Instinct GPU clusters), modern rack densities frequently climb to 60 kW–100 kW+.

3. How do in-rack CDUs mitigate the risk of liquid leaks damaging sensitive IT hardware?

The risk of fluid leakage is the primary concern for facility engineers deploying liquid cooling. Modern in-rack CDUs mitigate this through a combination of structural redundancy, smart telemetry, and alternative physics.
