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.

这项可行性研究通过减少能源需求来调查数据中心服务器的新型冷却解决方案。 ICT需求不断增长，它超过了ICT系统可持续能源管理中的技术发展。在过去的十年中，数据中心的能源使用率每年大约增长11％。但是，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。Extreme Low Energy -ELE以前已经开发了一种基于DC的基础架构，用于在非常低的能源水平上使用的运营台式计算机，这些基础台式计算机已在能源电网不可靠的非洲国家使用。 AC/DC电源的去除提供了提高的能量性能水平，并且在AC转换过程中还取消了大量的热量。与兰开斯特大学一起，该研究旨在使用压电执行器系统地评估替代空气移动系统的可行性，以取代传统风扇的基于DC的服务器冷却。它将在冷却效率，成本和稳健性方面分析该技术的潜力。此可行性研究将使用复杂的建模/仿真研究，实验测试和设计的结合来开发新的冷却系统，以实现服务器冷却的实际应用。重点将是使用压电执行器与DC Power解决方案的Datacentres一起使用的替代空气移动器冷却。
