ALLOWS (Advanced Liquid cooLing Of poWer electronicS)

ALLOWS项目是一项针对下一代电动汽车动力系统的电力电子先进液体冷却技术的可行性研究。HiETA Technologies Ltd和复合半导体应用弹射器（CSAC）分别是热管理和轻量化金属增材制造（MAM）组件和复合半导体技术的开发和生产领域的领导者。他们已经确定了电动汽车（EV）市场中电动动力系统所需的电力电子设备（主要是逆变器）高度集成冷却的构建模块。电动汽车的大规模部署需要更小、更轻、更高速度、更高效和更高功率密度的电动动力系统，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屏障，同时更有效地利用可用的冷却剂，以满足电动机的封装和温度控制要求。在评估了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之后，CSAC将收购一个现有的电力电子单元，并对其性能进行测试，为后续的改进提供基准。CSAC和HiETA将评估创新冷却方法的可行性，从优化现有封装到完全重新设计芯片组模块，以及使用HiETA最具创新性的单相或两相热交换表面和几何形状。在对热优化概念进行详细分析后，将在HiETA位于布里斯托的最先进的MAM工厂制造一系列技术演示装置，然后在位于纽波特的CASC测试和开发中心对当前技术进行性能测试。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ALLOWS项目将为实现和改进电动汽车中的下一代电力电子奠定基础。主要重点是使芯片组模块变得更加功率密度，效率和集成度更高，这将确保英国下一代电动机技术的发展。特别是，它将使电动机的功率密度超过20 kWe/kg，而最先进的功率密度为12%，从而使典型的EV质量减少约3%，范围增加高达10%。这不仅将促进下一代电动汽车的开发，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.
