GE研究，美国集团的研发翼GE,利用3 d打印技术来设计一个ultra-efficient, low-emission heat exchanger for power generation equipment. Called UPHEAT (Ultra Performance Heat Exchanger enabled by Additive Technology), the heat exchanger is part of a $2.5 M project led by GE Research.
该项目是通过高级研究计划局’S（ARPA-E）通过材料和制造工艺计划（hitemMP）的高强度热交换。在里面，GE研究与University of Maryland(UMD) and橡树岭国家实验室(ORNL).
在两年的过程中，合作者旨在“开发高温，高压和超压缩热交换器，该热交换器将在现有和下一代发电厂平台中使用3D打印在现有和下一代发电厂平台中产生更清洁，更有效的发电”。
“We’re taking our deep knowledge in metals and thermal management and applying it in ways we couldn’t have before through the power of 3D printing,” commented Peter deBock, a Principal Thermal Engineer for GE Research and project leader on the ARPA-E award.
“With 3D printing, we can now achieve new design architectures previously not possible. And this will allow us to create an ‘UPHEAT’ device that can operate cost effectively at temperatures 250°C (450°F) degrees higher than today’s heat exchangers.”
屏住呼吸的热交换器
Heat exchangers are widely used in a multitude of applications like space heating, refrigeration, and air conditioning. Specifically, GE Research is focusing on application in power generation equipment like gas turbines. Comparing its purpose to functions inside the human body, deBock says, “Lungs are the ultimate heat exchanger, circulating the air you breathe to keep the body functioning at peak performance while also regulating your body’s temperature. Heat exchangers in power generation equipment like a gas turbine essentially perform the same function, but at much higher temperatures and pressures.”
Eup -The The The The Heifeanger由GE Research专门用于添加剂制造的GE研究设计的镍超合金制成。该材料能够承受高温并具有抗裂纹。ORNL是腐蚀科学专家，将测试和验证所使用材料的长期性能。
Upon completion, the heat exchanger is expected to provide increased thermal efficiency of indirect heated power cycles, with reduced energy consumption and emissions. It will be capable of operating at temperatures up to 1,652 °F (900°C) and pressures up to 3626 psi (250 bar). With these properties, the UPHEAT could enable advanced applications in power and aerospace towards more energy efficient processes.
Debock补充说：“通过增材制造，GE和马里兰大学将探索更复杂的生物形状和设计，以使热交换器性能的逐步变化，从而提供更高的效率和较低的排放。”
高级金属添加剂制造与GE研究
GE Research，以前称为GE Global Research，目前是由国家3D印刷开发合作伙伴资助的项目的一部分America Makes要开发商业级，金属添加剂制造系统in collaboration with劳伦斯·利弗莫尔国家实验室（llnl）。由美国资助Air Force Research Laboratory（AFRL），该项目是Acceleration of Large-Scale Additive Manufacturing（ALSAM）来自美国制造的计划。
研发部门还开发了创建1：1量表的过程金属3D打印零件的双数字模型为了U.S. Navy。通过数字孪生process, the Navy will depend on GE to accelerate the production of mission-critical equipment.
“使用GE的数字双技术，我们的目标是快速加快使用3D打印过程重新设计或新创建的零件的时间，” GE Global Research Addive Technologies的主要工程师Ade Makinde说。
