Coolant Distribution Unit (CDU) High Capacity Cooling

Why Use A Coolant Distribution Unit?

Boyd’s Coolant Distribution Units (CDUs) help lower data center total cost of ownership. CDUs right-sized and custom configured for specific applications mean hyperscale compute systems get the exact, optimal cooling performance the system needs, when it needs it.

In Row Coolant Distribution Unit (CDU)

Freestanding In-Row Coolant Distribution Units (CDUs) are designed to manage high heat loads in hyperscale compute and data center environments. Full liquid cooling systems that distribute coolant in and out of a series of server chassis capable of tying into existing facility cooling systems or designed to be fully self-contained.

In Rack Coolant Distribution Unit

In Rack Coolant Distribution Units (CDUs) are designed to integrate into a server chassis and distribute coolant to a series of servers or heat sources. In-rack CDU configurations are available for 2U and 4U space and feature redundancy pump design, dynamic condensation-free control, automatic coolant replenishing, a bypass loop for stand-by operation and automatic leak detection.

Coolant Distribution Unit Components

CDU components typically include manifolds, rear door heat exchangers and/or a reservoir pumping unit (RPU) for full liquid cooling system functionality.

Maximize Compute Density

Compact, high thermal density cooling systems open up more design space in rack design.

Reliable Field Performance of Boyd CDUs

Coolant Distribution Units are essential components that ensure liquid cooled servers meet or exceed lifetime expectations. Operation logic integrated into intelligent controllers, automatic diagnostics, warnings, and troubleshooting, in addition to smart flow, pressure, and temperature controls manage server cooling system performance. Advanced system controls respond to peak demands while remaining economical and efficient during non-peak operation and prevent problems before they occur. Blind mate quick disconnects with 360 swivel fittings make servicing data server cooling systems fast for minimized maintenance downtime.

Decades of reliable field performance have enabled Boyd to fine tune system design in liquid cooled servers with validated thermal reliability and leak-free performance for optimal data center cooling. When server or chassis heat loads outpace what traditional air-cooled systems can achieve, CDUs offer higher thermal performance for in-row and server rack cooling. A liquid cooled server negates the need for bulky heat sinks, fan trays, and components in data center cooling systems that create significant environmental noise pollution and consume more energy.

Coolant Distribution Unit Flexibility and Space-Saving Benefits

In a server cooling system, integrated CDUs enable greater processing power density with quieter operation and more efficient natural resource utilization. Integrate in-rack CDUs directly into facility water or facility-level cooling systems for direct rack server cooling or design self-contained in-row cooling that offer the next level of flexibility for liquid cooled servers. Leverage CDU cooling capacity to cool the rack, chassis, or blade down even to the processor or silicon. CDUs can be designed to integrate into existing data center or chassis configurations.

 

The flexibility and space-saving benefits of in-row cooling and rack server cooling may enable data center and chassis designers to completely rethink footprint configuration opportunities to maximize power density. Boyd in-rack and in-row CDUs are designed to meet IEC62368-1 and tested to withstand 3X maximum working pressure. All new subcomponent designs undergo harsh maximum pressure testing to destruction to ensure reliable data and server cooling systems. Reliability testing incudes thermal cycling, min /max storage and packaging testing.
