Abstract Scope |
An integral component in two-phase thermal management systems, namely heat pipes (HP) and vapor chambers (VC), is a porous wicking structure. Traditional methods for manufacturing wicking structures for HPs and VCs involve secondary manufacturing processes and are generally limited to simple geometries. More complex geometries and part consolidation may, however, be possible with laser powder bed fusion (LPBF) additive manufacturing (AM). This work aims to leverage the unprecedented level of customization and design freedom of LPBF AM to produce HPs and VCs with integrated wicking structures. Several copper wicking structures were successfully fabricated with capillary performance, K/reff, ranging from 0.186 μm to 1.74 μm. Several VCs, with integrated wicking structures, were then fabricated and tested to validate the printability of complete and functional assemblies of copper HPs and VCs |
