3 Sizes of CDU`s multiple configurations. Without CDU you cannot liquid Cool
The Coolant Distribution Unit is exactly what is says it is, It simply pumps the liquid at the desired temperature directly onto the chip or server. This can be seen as the middle-man for the cooling infrastructure to the IT.
Why do we need two loops for liquid cooling?
- For high quality facility water which is not available in most Data Centers - a secondary loop is required between the CDU and the cold plates. This helps achieves the highest quality of water while keeping WUE low
- Precision control of the coolant
- the CDU can control the pressure, flow and temperature.
IMPROVED COOLING PERFORMANCE
Coolant distribution units serve as the vital core of liquid-cooled data centers, functioning as the beating heart that sustains optimal operating conditions.
These units play a critical role in effectively managing the distribution of coolant throughout the intricate network of servers and equipment, ensuring efficient heat dissipation and maintaining stable temperatures within the facility. By regulating the flow of coolant, these units enable data centers to operate at peak performance levels while reducing energy consumption and enhancing overall system reliability.
Their strategic placement and precision engineering underscore their significance in the seamless operation and longevity of liquid-cooled data centers, making them indispensable components in the realm of high-performance computing infrastructures.
BENEFITS OF COOLANT DISTRIBUTION UNITS
Liquid cooling through Coolant Distribution Units (CDUs) has revolutionized cooling performance in data centers, offering unparalleled efficiency and enhanced thermal management capabilities.
By utilizing liquid as a cooling medium, CDUs facilitate the transfer of heat more effectively than traditional air cooling methods, allowing for greater heat dissipation and improved temperature regulation.
This advanced cooling technology not only optimizes the thermal management of servers and equipment but also enables data centers to operate at higher power densities without compromising performance or reliability.
OPTIMISING THERMAL MANAGEMENT WITH CDU SOLUTIONS
The precision control and efficiency of liquid cooling systems through CDUs have significantly contributed to reducing energy consumption, minimizing carbon footprint, and maximizing the overall cooling performance of modern data centers, making them a cornerstone of sustainable and high-performance computing infrastructures.
