Extreme Low Energy Server Cooling

本可行性研究通过降低能源需求，研究了一种新的数据中心服务器冷却解决方案。日益增长的信息通信技术需求超过了信息通信技术系统可持续能源管理方面的技术发展。在过去十年中，数据中心的能源使用量以每年约11%的速度增长。然而，大约33%的能源消耗是由于传统对流风扇提供的机械冷却，以冷却服务器。极低能耗——Ele之前开发了一种基于直流的基础设施，用于在非常低的能耗水平下操作台式电脑，这种基础设施已在电网不可靠的非洲国家使用。去除AC/DC电源提供了改进的能源性能水平，也消除了在AC到DC转换过程中产生的大量热量。与兰开斯特大学一起，这项研究旨在系统地评估一种替代空气移动系统的可行性，该系统使用压电致动器取代传统的直流服务器冷却风扇。它将分析该技术在冷却效率、成本和稳健性方面的潜力。这项可行性研究将结合复杂的建模/模拟调查、实验测试和设计，为服务器冷却的实际应用开发新的冷却系统。重点将放在使用压电驱动器的替代空气驱动器的冷却上，并结合数据中心的直流电源解决方案。

This feasibility study investigates a novel cooling solution to servers in datacentres, by reducing the energy demand. The growing ICT demand is outpacing technological developments in sustainable energy management for ICT systems. The energy usage of datacentres has a growth of roughly 11% per year over the last decade. However, around 33% of the energy consumption is due to the mechanical cooling provided by conventional convection fans, in order to cool the servers.Extreme Low Energy - Ele has previously developed a DC based infrastructure for operating desktop computers at very low energy levels, which have been used in African countries where energy grids are unreliable. The removal of AC/DC power supplies has delivered improved energy performance levels and has also removed a lot of heat created during the AC to DC conversion process. Together with Lancaster University, this study is intended to systematically assess the feasibility of an alternative air moving system using piezoelectric actuators replacing conventional fans for DC based server cooling. It will analyse the technology's potential in terms of cooling efficiency, costs and robustness.This feasibility study will develop new cooling systems for practical applications of server cooling using a combination of sophisticated modelling/simulation investigations, experimental testing and design. The focus will be on cooling by alternative air movers using piezoelectric actuators, combined with DC power solution for datacentres.
