Additive Manufacturing Aluminum Heat Exchanger (AMAHE)

航空业正在推动下一代飞机更轻、更高效。实现这一目标的一种方法是将热交换器设计集成到越来越多的飞机部件中。热交换器（HE）用于飞机上，通过集成复杂的冷却通道和腔体，将热量从关键部件转移出去，使部件能够在更高的工作温度下使用。到目前为止，HE设计一直受到传统制造技术的限制。在这里，我们介绍了普惠加拿大公司和麦吉尔大学之间的一个合作项目，利用激光粉末床融合（LPBF）增材制造来解决与传统制造技术相关的问题，以研究he集成组件。LPBF是一种逐层生产技术，允许设计师自由地生产以前无法想象的零件，而无需二次加工。这种技术非常适合于传统飞机部件的制造和HE设计。一层一层的生产允许结合复杂的冷却通道，薄壁部分和定制的表面粗糙度，以最大限度地提高表面积，从而实现传热。该项目涉及P&WC定制热交换器组件的设计，然后将在麦吉尔大学进行打印和表征，以阐明该方法在未来技术创新中的潜力。其次，麦吉尔大学将研究一种正在申请专利的合金成分的潜力，该成分具有专门为HE航空航天环境量身定制的性能。该工作项目将培训2名硕士学生，由Brochu教授团队的一名RA和一名技术员协助。

The aviation industry is pushing the next generation of aircrafts for lighter and more efficient planes. One approach to achieve this goal is the integration of heat exchanger designs into more and more aircraft components. Heat exchangers (HE) are used in aircrafts to transfer heat away from critical components by integrating complex cooling channels and cavities, facilitating the parts to be used to higher operating temperatures. Up until now HE designs have been limited by the constraints of traditional manufacturing techniques. Here we present a collaborative project between Pratt & Whitney Canada and McGill University to utilise Laser Powder Bed Fusion (LPBF) Additive manufacturing to counteract the issue associated with traditional manufacturing techniques to study HE-integrated component. LPBF is a layer by layer production technique which allows designers freedom to produce previously unimaginable parts without the need for secondary machining. This technique is perfectly suited to the manufacturing and inclusion of HE designs into conventional aircraft components. The layer by layer production allows the incorporation of complex cooling channels, thin wall sections and tailored surface roughness to maximise surface area, and therefore heat transfer. This project involves the design of bespoke heat exchanger components by P&WC, which will then be printed and characterised at McGill University to elucidate the potential of this methodology for future technological innovation. Second to this, McGill University will investigate the potential of a patent pending alloy composition with specifically tailored properties for HE Aerospace environments. The work project will train 2 M.Eng students, which will be assisted by one RA and one technician from Prof. Brochu's team.
