Highly Compact Metallic Heat Exchangers for Extreme Environments
Project Innovation + Advantages:
The Boeing Company will develop a compact, extreme environment heat exchanger (EEHX) for application in supercritical carbon dioxide electric power generation cycles for hypersonic aircraft and land-based distributed power generation. Their metallic heat exchanger will be capable of operation at temperatures and pressures in excess of 1000°C (1832°F) and 80 bar (1160 psi), respectively. The team will design topologically optimized geometries and develop multifunctional, complex concentrated alloys that are expected to offer superior high temperature durability and thermal conductivity, as well as lower thermal expansion compared with state-of-the-art systems. The team will use advanced manufacturing approaches, including combinations of additive and subtractive manufacturing, powder metallurgy, superplastic forming, and solid-state bonding to fabricate the EEHX.
HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.
