Emerson Network Power is touting direct server cooling technology this week as it rolls out its new Liebert XDS server cooling system.
Liebert XDS from Emerson Network Power brings refrigerant-based cooling directly to the server while eliminating cooling system and server fans.
The first Liebert XD system was introduced in 2003. In 2009, Emerson introduced the Liebert XDR rear door heat exchanger, which eliminated cooling system fans by using server fans to provide airflow through the rack. Now, the fanless Liebert XDS runs silently.
The Liebert XDS consists of a standard-sized IT rack equipped with patent-pending cold plate server cooling technology from Emerson’s technology partner, Clustered Systems. The cooling plates are configured to use refrigerant supplied by a Liebert XDP refrigerant pumping unit.
According to Emerson, heat generated by the server is transferred through heat risers to the server housing, then through the thermal interface material lining the cover, and finally transferred to a cooling plate, which uses refrigerant-filled microchannel tubing to absorb the heat.
In the promotional video below, Emerson Network Power explains its new Liebert XDS server cooling system.
