In-Rack CDU for Ultra-High Performance and Low PUE Operation

The In-Rack Liquid-to-Air Coolant Distribution Unit (CDU) series pushes rack-level thermal performance beyond conventional limits with a disruptive dual-mode cooling architecture. By dynamically adjusting the balance between air cooling and liquid cooling, the system delivers a maximum heat dissipation density of up to 12 kW (3 kW per 1U) within a compact 4U footprint—several times the capacity of traditional air-cooled solutions.

Designed for next-generation liquid cooling data center and liquid cooled server deployments, the CDU enables ultra-precise temperature regulation with ±0.5 °C control accuracy. This rapid thermal response suppresses GPU thermal runaway within seconds, significantly improving system stability while reducing overall PUE to as low as 1.15. Inlet and outlet water temperatures are maintained at an efficient 40–50 °C, allowing seamless integration with warm-water cooling loops and improving total energy utilization.

Customers can save 33% of cabinet space and provide a full-scenario energy efficiency revolution from edge computing to supercomputing clusters.

FAQ:

What is the difference between Liquid-to-Liquid and Liquid-to-Air CDUs?

Liquid-to-liquid CDUs transfer heat to the facility's chilled water circulation system, offering the highest efficiency and making them ideal for high-density environments. In contrast, liquid-to-air CDUs directly release heat into the indoor air, making them suitable for facilities without a dedicated chilled water system.

2.How does a CDU improve data center PUE and efficiency?

A: A CDU improves data center efficiency by providing targeted liquid cooling, which lowers the Power Usage Effectiveness (PUE). By enabling the use of warmer facility water, CDUs reduce the need for energy-intensive chillers and increase the opportunities for free cooling, saving both energy and operational costs.

3.What is the role of a CDU in liquid cooling?

The Coolant Distribution Unit (CDU) acts as the critical interface between the facility’s chilled water and IT equipment. It separates loops, regulates coolant temperature above the dew point to prevent condensation, and ensures precise flow control, making liquid cooling safe and efficient.
