| Abstract Scope |
As more stringent size, weight, and power (SWaP) constraints are imposed on thermal management solutions, the necessity for more efficient passive cooling systems becomes more urgent. Passive two-phase heat spreaders, such as vapor chambers, which utilize several thin geometries that act as wicking structures to create an overall phase-changing slug flow, are very effective at dissipating high heat fluxes; however, their geometries are often extremely difficult to manufacture due to their small and complex size within a hermetically sealed chamber. The use of additive manufacturing allows for the creation of vapor chambers with more complex internal geometries and space-efficient/conformal form factors. This study will provide the several design steps for additive manufacturing taken to ensure the successful fabrication and de-powdering of a state-of-the-art AlSi10Mg vapor chamber produced via laser powder bed fusion (L-PBF). The vapor chamber thermal performance as measured through controlled experiments will also be provided. |
