Direct-to-Chip, Hot Water Liquid Cooling for Data CentersRackCDU D2C is a “free cooling” solution that captures between 60% and 80% of server heat, reducing data center cooling cost by over 50% and allowing 2.5x-5x increases in data center server density. D2C removes heat from CPUs, GPUs, memory modules within servers using water as hot as 40°C (105°F), eliminating the need for chilling to cool these components.Chilling is the largest portion of data center cooling OpEx and CapEx costs. With RackCDU D2C, less air needs to be cooled and moved by Computer Room Air Handlers (CRAH) or Computer Room Air Conditioning (CRAC) units. Further, liquid cooled servers need less airflow resulting in more energy efficient servers.

 RackCDU™ is capable of returning water from the data center at temperatures high enough to enable waste heat recycling. Data centers choosing this option recover a portion of the energy running their servers further increasing energy cost savings, reducing carbon footprint and resulting in cooling Energy Reuse Efficiencies (ERE) below 1.0! RackCDU D2C is deployed at a rack/server level providing maximum scalability. The system consists of a zero-U rack level CDU (Cooling Distribution Unit) mounted in a 10.5 inch rack extension that includes space for 3 additional PDUs, and direct-to-chip server coolers that are drop in replacements for standard server air heat sinks.
