摘要：

This study presents a comprehensive quality assessment of additively manufactured (AM) heat exchanger (HX) components using robotic X-ray computed tomography (CT). Three complex geometries, namely WAVY, OSF, and TPMS, were fabricated using Laser Powder Bed Fusion (LPBF) and analyzed at both specimen and prototype scales. CT enabled non-destructive evaluation of internal features, focusing on depowderability, thin-wall dimensional accuracy, and porosity detection. The results demonstrate the effectiveness of robotic CT in identifying internal defects and verifying geometric fidelity, thereby supporting its integration into qualification protocols for AM heat exchangers. Future work will involve in-situ pressurization tests to assess leak-tightness and correlate CT findings with functional performance. © 2025 The Authors.
