Direct Liquid Cooling in Hyperscale Data Centers – Empowering AI
For hyperscalers, artificial intelligence is a key growth market. However, the rapid escalation in the performance of AI servers also poses a number of challenges. Increased performance densities mean higher heat loads, and therefore demand significantly more cooling output. Air cooling systems are being pushed to their limits. The solution? Direct liquid cooling where the cooling liquid passes directly over the chip where most of the heat is generated.
A hyperscale infrastructure is designed for scalability, high availability, and easy servicing. Rittal has designed a direct liquid cooling (DLC) portfolio tailored to the needs of hyperscalers. All solutions allow effortless integration into the existing IT infrastructure and are designed for maximum efficiency, so your IT systems can operate at maximum performance without consuming unnecessary energy.
Our Liquid Cooling Portfolio
One megawatt!
The cooling output delivered by Rittal’s most powerful Coolant Distribution Unit (CDU) In-Row.
Our DLC portfolio offers four different solutions with cooling outputs ranging from 38 kW to 1 MW.
Liquid-to-Air Solutions:
-
38 kW: Rear Door HEx with Coolant Circulation Unit (CCU)
-
50 kW: Side Cooler with CCU
Our liquid-to-air solutions cool heat-generating components like the AI chip using a water/glycol mixture, which is air-cooled via the rear door of the rack or a side cooler. They are used in individual IT racks or in data centers with medium heat losses.
Liquid-to-Liquid Solutions:
-
150 kW: CDU In-Rack
-
1 MW: CDU In-Row
In our liquid-to-liquid solutions, the water/glycol mixture is cooled by the building’s own water supply. Liquid cooling removes significantly more heat than air cooling. Liquid-to-liquid solutions are used in data centers with a medium heat loss, as well as in high-performance data centers.
Always Available and OCP-Compatible
Maximum operational reliability: The integral redundancy options included with Rittal Direct Liquid Cooling keep your systems permanently available. The hot-swap function allows you to replace critical components while the system is running; no need to interrupt operations. This helps avoid expensive system downtime and keep maintenance times to a minimum.
Reliable delivery: Our dependable production capacity guarantees on-time deliveries, even for large-scale requirements. Your data centers are rapidly scalable without delay.
Tailored solutions: You benefit from a team of interdisciplinary experts who will support you with technical advice and develop solutions tailored to your specific requirements.
Maximum efficiency: For many years, Rittal has been actively involved in OCP projects and has adapted its Direct Liquid Cooling solutions to suit the OCP architecture. We help standardize your data center structures to save you money and energy.
Direct Liquid Cooling – Modular, Platform-Based Solutions
Flexible scaling and simple integration: Our modular concept and uniform architecture means that solutions are readily integrated into existing infrastructures and easily adapted to keep pace with growth.
Maximum reliability: Component-based leak monitoring proactively protects your infrastructure from water damage and ensures long-term operational reliability.
Minimal waiting times: The sensors, controller, and pumps of the CDU In-Row can be replaced while the system is operational. This helps to maintain constant cooling and minimize downtime.
Individual modifications for your infrastructure: Custom distributor channels (manifolds) allow flexible, efficient distribution of the cooling fluid.
Reliable power supply: A DC busbar ensures a stable, energy-efficient power supply in data centers based on OCP architecture while protecting your IT from power outages.
