ALLOWS (Advanced Liquid cooLing Of poWer electronicS)

项目ALLOW是一项关于电力电子先进液体冷却与下一代电动汽车动力系统相关的可行性研究。HiETA Technologies Ltd和化合物半导体应用公司Catapult(CSAC)分别是开发和生产用于热管理和轻量化的金属添加剂制造(MAM)组件以及化合物半导体技术领域的领先者。他们已经确定了电动汽车(EV)市场中电动汽车动力总成所需的电力电子产品(主要是逆变器)的高度集成冷却的构建块。电动汽车的大规模部署需要更小、更轻、更快、更高效和更高功率密度的电动总成，这反过来又需要为所有组件，特别是逆变器提供创新的冷却解决方案。CSAC和HiETA正在联合开发更高效的冷却系统，以减少甚至消除电子元件和冷却剂之间的一些热障碍，同时更有效地利用可用的冷却液，以满足电动汽车的封装和温度控制要求。在评估最先进的汽车电力电子模块及其技术、商业和环境挑战和机遇后，CSAC将收购现有的电力电子设备并测试其性能，为后续改进提供基准。CSAC和HiETA将从优化现有封装的角度评估创新冷却方法的可行性，完成芯片组模块的重新设计，并使用HiETA最具创新性的单相或两相换热表面和几何结构。在对热优化概念进行详细分析后，将在HiETA位于布里斯托尔的最先进的MAM设施中制造一系列技术演示单元，然后在CASC位于纽波特的测试和开发中心进行针对当前技术的性能测试。将对复杂供应链中的商业化和批量生产进行调查。成功完成项目ALOMS将为实现和改进电动汽车中的下一代电力电子产品奠定基础。使芯片组模块变得更密集、更高效和更集成的主要重点将确保英国下一代电机技术的发展。特别是，它将使电动马达的功率密度从最先进的12%发展到20kWe/kg以上，导致典型电动汽车质量减少约3%，续航能力提高高达10%。这不仅将促进下一代电动汽车的发展，还将在快速增长的全球市场中直接创造设计、制造和供应链机会。

Project ALLOWS is a feasibility study into the Advanced Liquid Cooling of Power Electronics in relation to next generation Electric Vehicle Powertrains.HiETA Technologies Ltd, and the Compound Semi-conductor Applications Catapult (CSAC) are leaders within their fields of the development and production of Metal Additive Manufacture (MAM) components for thermal management and light-weighting, and compound semi-conductor technologies respectively. They have identified the building blocks for highly integrated cooling of the power electronics, mainly inverters, needed for e-powertrains in the electric vehicle (EV) market. Mass deployment of EVs requires smaller, lighter, higher speed, more efficient and more power-dense e-powertrains, which in turn require innovative cooling solutions for all components, particularly the inverters. CSAC and HiETA are combining to develop more efficient cooling systems that reduce or even eliminate some of the thermal barriers between electronic components and coolant, while making more efficient use of the coolant available, to meet the packaging and temperature control requirements of the e-motor.After assessing state-of-the-art Automotive Power Electronics Modules and their technical, commercial and environmental challenges and opportunities, CSAC will acquire a current power electronics unit and test its performance to provide a benchmark for subsequent improvement.CSAC & HiETA will then assess the feasibility of innovative cooling methods, from optimisation of current packages, to complete redesign of chipset modules and the use of HiETA's most innovative single or 2-phase heat exchange surfaces and geometries. After detailed analysis of thermally optimised concepts, a selection of technology demonstrator units will be manufactured at HiETA's state-of-the-art MAM facility in Bristol, and then performance tested against current technology at CASC's test and development centre in Newport. An investigation into commercialisation and volume production within a complex supply chain will be investigated.Successfully completing Project ALLOWS will give the foundation for the realisation and improvement of next generation Power Electronics within EV. The primary focus in enabling chipset modules to become more power dense, efficient and more integrated will ensure the evolution of next generation electric motor technology in the UK. In particular, it will enable the development of e-motors with power densities of over 20 kWe/kg compared with the state-of-the-art 12%, resulting in a decrease in typical EV mass of ~3% and an increase in range of up to 10%. Not only will this allow the development of next generation EV's but it will directly create design, manufacturing and supply chain opportunities in a rapidly increasing global market.
