Abstract Scope |
Laser Powder Bed Fusion of copper paves the way for innovation in thermal systems and heat transfer devices. Recent simulations have shown that by interchanging typical fin designs with more complex structures an overall improvement in pressure drop and weight can be obtained while offering the same thermal performance. Small-scale lattice structures are especially of interest for AM as they form a reliable, periodic infill. However, until now, their study has been mainly theoretical. To analyse these structures, an in-house built LPBF machine at KU Leuven has been successfully used to manufacture pure copper parts. Measurements showed a conductivity exceeding 100%IACS, which is the result of low contamination and low porosity in the as-built material. In this work, the parameter optimisation for thin-walled lattices is discussed in combination with an in-depth review of the thermal properties of the resulting structures. |
