Typical Air Cooled Data Centre Room Size: 382m² Room Density: 2.1KW / m2 96 Server Cabinets: 7KW per cabinet Total: 672KW 32 Network Cabinets: 56KW Network Equipment Total Heat Load: 810KW CRAC Units: 6 Hot Aisle and Cold Aisle configuration Cold Aisle containment
Transition to Liquid Cooling Removal of thermal barriers Heat sinks replaced by direct contact liquid cold plates Circulating liquid coolant takes heat directly away from the roomAir flow requirement significantly reduced at server level Air flow requirement significantly reduced at room level Reduction of fan power required by CRAC units
Servers: Air versus Liquid A thermal model showing the difference in temperature between a standard air cooled server and one with liquid direct to the components Air Cooled Water Cooled
Liquid Cooled Data Centre Potential Advantages of Water Cooling Compute Capacity Doubled Ability to implement high performance CPUs Reduction in server fan power Energy Savings Accurate control of processor temperature
Development of Nanofluids Studies have shown that the dispersal of carefully engineered nanoparticles into a fluid can improve heat transfer by up to 10%. The integration of a nanofluid into a liquid cooling system could offer even further benefits in data centre performance. NanoHex is an €8.3m pan European project working to develop a cutting edge nanofluid coolant. Led by thermal management specialists Thermacore Europe, NanoHex hopes to integrate the coolant within data centre cabinets using a custom built cold plate to draw heat directly away from the processing chips.
Thermacore EuropeThermacore Europe have developed • Can be adapted to fita unique liquid cooling device different server designs(below) ready for integration into aserver or data centre environment. • Can remove up to 500W • Delivers coolant direct to the processors • Reduces of thermal barriers • Stainless steel, sealed system minimises risk of leakage • Could double compute capabilities of a data centre
