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.

这项可行性研究旨在通过降低能源需求，为数据中心的服务器提供一种新型的冷却解决方案。不断增长的信通技术需求超过了信通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的对流风扇提供的机械冷却，以冷却服务器。Extreme Low-Ele之前开发了基于DC的基础设施，用于在非常低的能量水平下操作台式计算机，已在能源电网不可靠的非洲国家使用。AC/DC电源的移除提高了能效水平，也消除了AC-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使用压电致动器取代传统风扇用于基于DC的服务器冷却的替代空气输送系统的可行性。它将从冷却效率、成本和坚固性方面分析该技术的潜力。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致动器的替代空气推进器的冷却上，并结合数据中心的直流电源解决方案。
