Enhancement of heat exchanger performance using additive manufacturing of gyroid lattice structures

The main objective of this research is to investigate the capability of laser powder bed fusion (LPBF) to manufacture complex heat exchangers with gyroid-shaped channels. First, the gyroid’s geometric features are investigated including the network type, thickness, unit cell size, and aspect ratio. Computational fluid dynamics (CFD) were used to screen these designs based on their thermal and fluid dynamics performance. Then, the …
