Friction Stir Channeling: An Innovative Technique for Heat Exchanger Manufacturing

这项研究计划是针对一个新的创新，摩擦搅拌通道（FSC）。FSC在单片板上产生连续的孔。该计划的目标是：(a)工艺开发以产生一个整体通道（也称为保形通道），(b)通道周围材料的微观结构-性能相关性，以及(c)通道形状、尺寸和表面特性对热交换器性能的影响。通用工具公司和美国宇航局约翰逊航天中心是这个项目的合作伙伴。该工艺能够在机器人搅拌摩擦焊机的复杂部件上产生非线性通道。FSC作为“技术推动者”提供了几个新的机会。一些例子是：板中的整体式通道，半导体加工设备的管状部件中的冷却通道，以及保形冷却通道。这项计划可能会产生几个更广泛的影响。在教育方面，它将为金属变形加工和金属结构性能实验室等本科课程带来创新理念。本科研究人员将通过UMR- oure计划参与，并得到UMR摩擦搅拌处理中心的支持。热交换器通常用于改变操作系统的温度或传热，总市场规模达数十亿美元。摩擦搅拌通道有可能在这个市场的几个子组件中产生影响，特别是压铸和永久模具行业，冷板热交换器和半导体加工设备。通用工具公司是搅拌摩擦焊接和加工设备的主要制造商之一，他们的参与将导致技术转移和成功实施。

This research program is directed towards a new innovation, Friction Stir Channeling (FSC). FSC produces a continuous hole in a monolithic plate. The objectives of this program are: (a) process development to produce an integral channel (also referred as conformal channel), (b) microstructure-property correlation of material around the channel, and (c) influence of channel shape, size and surface characteristics on performance of the heat exchanger. General Tool Company and NASA-Johnson Space Center are partners in this program. The process is capable of producing non-linear channels on a complex component with robotic friction stir welding machine. FSC offers several new opportunities as 'technology enabler.' Some examples are: integral channel(s) in a plate, cooling channels in tubular parts for semiconductor processing equipment, and conformal cooling channels. This program is likely to have several broader impacts. On the educational front, it will bring innovative ideas to undergraduate courses such as metal deformation processing and metals structure-property laboratories. Undergraduate researchers will be involved through the UMR-OURE program and the support from the Center for Friction Stir Processing at UMR. Heat exchangers are commonly used to alter the temperature of an operating system or heat transfer and total market is several billions of dollars. Friction stir channeling has the potential to create impact in several sub-components of this market, specifically, die casting and permanent mold industries, cold plate heat exchangers and semiconductor processing equipments. General Tool Company is one of the leading manufacturers of friction stir welding and processing machines and their involvement will result in technology transfer and successful implementation.
