The Liebert XDK, a Knurr rack enclosure with integrated cooling capabilities, is a 19-inch rack now available in the United States. It provides secure and reliable cooling for up to 17 kW of high-density electronics. The unit utilizes water as the fluid to transport the heat out of the enclosure. It is a closed architecture solution utilizing air circulation internal to the enclosure that is completely sealed from room air and environmental conditions. Server heat load is absorbed by the rack’s integrated cold water system through a high-efficiency air-to-water heat exchanger in the bottom of the rack. This solution enables IT professionals to deploy blade servers and other high-density heat load computing equipment without creating hot spots in their data centers. Redundant high-performance fans, with temperature-dependent speed regulation, drive closed loop air circulation in the rack’s interior, while servers are supplied with cold air at the front of the rack.
