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 explores the manufacturability of Inconel 718 wicking structures for implementation into high-temperature Inconel HP/VC. Several Inconel 718 wicking structures were successfully fabricated with promising capillary performance. An anticipated future outcome is fabrication of a complete assembly of an Inconel 718 HP/VC with sodium metal as a working fluid. |
