COOLING SUCH HIGH-DENSITY DATA CENTRES IS A CONSTANT CHALLENGE , AGGRAVATED BY THE EXTREME CLIMATIC CONDITIONS IN THE REGION .
THE EDGE s Middle East organisations increasingly turn to AI ,

A Big Data , cloud and IoT to optimise processes , the data centres that power these operations are expanding at an unprecedented rate . Huawei has recently updated its own UPS power module lineup with the launch of the new FusionPower2.0 , a solution that addresses some of the primary network challenges facing businesses in the region .

To start , the FusionPower2.0 enables the power density of a single module to reach 100 kW / 3 U , which is twice the industry standard . Based on the 100 kW module , the UPS achieves the ‘ one megawatt , one cabinet ’ principle , with a footprint that is more than halved compared with the traditional end-to-end parallel solution . The power supply and distribution system leave more space for data centre cabinets , enabling customers to increase revenue .
Yet cooling such high-density data centres is a constant challenge , aggravated by the extreme climatic conditions in the region . The Huawei 100 kW UPS power module design employs the U-shaped symmetric architecture , incorporating a wide range of heat dissipation and an optimal module layout . The symmetric architecture features a combination of small air resistance and fast heat dissipation . In addition , extended ventilation channels have made it possible to achieve widerange heat dissipation . Furthermore , closely coupled cooling eliminates hotspot concentrations .
Due to the optimised heat dissipation design , Huawei UPS systems can function at 40 ° C for extended periods without derating . While patented innovative components further improve the heat dissipation capability , grooves on the heat sink enhance the convective heat transfer coefficient , improving heat dissipation by 10 %.
Furthermore , patented inductors with vertical windings improve winding heat

dissipation by 50 %. Compared with an aluminum heat sink , the patented multi-cavity redundant vapor chamber increases heat dissipation by 20 %. In addition , proper matching between fans and air channels and a refined air volume control together significantly improve the heat dissipation efficiency of fans .
To arrive at this design , Huawei leveraged the multi-physical-field simulation platform at the Thermal Lab of the Huawei Laboratories .
Huawei engineers utilise advanced software through simulation to predict the airspeed and temperature field of UPS components , boards and systems . www . intelligentdatacentres . com
