Electric motors (e-motors) consume more than 40% of electricity produced globally. The EU aims to save ~40Mt of CO2 emissions per year until 2030 by deploying more efficiency e-motors. E-motors are also the driving force behind EVs, currently leading the global efforts for decarbonisation of the transportation sector; their efficiency is crucial in extending EV mileage. Unfortunately, electrification plans for heavy-duty, earth-moving machines and aircrafts (accounting currently ~60% of fossil fuel consumption in transportation) have to overcome, among other limitations, the technological barrier of excess heat generated in the e-motor copper windings during power demanding operations associated with these sectors. E-COOL promises to address this challenge via the development of a holistic e motor cooling technology, maximising heat transfer through direct-contact, spray cooling. E-COOL aims to achieve this technological breakthrough at time-scales compatible to those required for industrial innovation to reach the market, by integrating two interdisciplinary activities: (a) development and manufacturing of novel oil-based, dilute polymer mixtures of non-Newtonian nature, which, when employed in spray-cooling thermal management systems, will be a game-changer; (b) implementation of a universal design methodology for spray cooling, optimised with the aid of new Machine Learning (ML) algorithms. Training datasets for the ML tool will be obtained by ‘ground-truth’ experimental and numerical investigations also to be conducted for the first time in E-COOL. The envisioned cooling system aims to provide unprecedented cooling rates at local temperature hot spots, which can contribute to an average 20% increase in e-motor’s efficiency compared to today’s state-of-the-art. This will allow next-generation e-motor utilisation over the whole range of transportation sectors, thus, facilitating significant additional energy and CO2 savings relative to the existing EU plans.

电动机（E-Motors）消耗了全球生产的40％以上的电力。欧盟的目标是通过部署更多效率电子机能来节省约40毫升的二氧化碳排放，直到2030年。电子机动器也是电动汽车的驱动力，目前正在领导全球运输部门脱碳的努力。他们的效率对于延伸EV里程至关重要。不幸的是，重型，移动机器和飞机的电气化计划（目前约60％的运输燃料消耗的60％）必须克服，除其他限制外，还需要在与这些部门相关的功率运营过程中产生的E-Motor铜盘绕组中产生的过量热量的技术障碍。电子酷有望通过开发整体电子运动冷却技术来应对这一挑战，从而通过直接接触，喷雾冷却来最大化热传递。电子酷的目的是通过整合两项跨学科活动来实现与工业创新到达市场所需要的时间量表的这一技术突破：（a）新型油性油基，稀释的非纽顿性质混合物的开发和制造，当在喷雾冷却热管理系统中使用时，该混合物是一种雇用的，该系统将是一种游戏，将是一种游戏，将是一种游戏，将是游戏 - 型游戏 - 更改游戏； （b）借助新机器学习（ML）算法，实施用于喷雾冷却的通用设计方法。 ML工具的培训数据集将通过“地面真相”实验和数值投资获得，也将首次在电子酷进行中进行。设想的冷却系统旨在在局部温度热点下提供前所未有的冷却速率，与当今的最先进相比，E-Motor的效率平均可以提高20％。这将允许在整个运输领域的下一代电子机动器利用率，因此，相对于现有的欧盟计划，可以促进额外的额外能源和二氧化碳节省。
