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.

电动马达消耗了全球 40% 以上的电力，欧盟的目标是通过部署更高效的电动马达，在 2030 年之前每年减少约 40 吨二氧化碳排放。目前正在引领全球交通运输行业的脱碳工作；不幸的是，重型土方机械和飞机的电气化计划（目前正在考虑）对于延长电动汽车行驶里程至关重要。交通运输中约 60% 的化石燃料消耗）必须克服与这些行业相关的电力需求运行期间电机铜绕组中产生过多热量的技术障碍，E-COOL 有望通过这一技术解决这一挑战。开发整体电机冷却技术，通过直接接触喷雾冷却最大化传热，旨在通过整合两个跨学科，在与工业创新进入市场所需的时间尺度相匹配的时间尺度上实现这一技术突破。活动：(a) 开发和(b) 实施喷雾冷却的通用设计方法，并借助新的机器学习 (ML) 算法进行优化，还将通过“地面实况”实验和数值研究来获得 ML 工具的训练数据集。首次在 E-COOL 中设想的冷却系统旨在在局部提供前所未有的冷却速率。与当今最先进的技术相比，这可以使电动马达的效率平均提高 20%，这将使下一代电动马达在整个运输领域得到利用，从而促进。相对于现有的欧盟计划，可显着节省更多能源和二氧化碳。
