Abstract
A sandwich panel heat pipe with a three-dimensional ordered open-cellular micro-truss core and a method creating the same. In one embodiment, the sandwich panel heat pipe includes a first face sheet, a second face sheet, the three-dimensional ordered open-cellular micro-truss core between the first face sheet and the second face sheet, and a working fluid in the ordered open-cellular micro-truss core. Here, the three-dimensional ordered open-cellular micro-truss core includes a vapor region and a liquid region, the vapor region is for transporting a vapor phase portion of the working fluid to the liquid region, and the liquid region is for transporting a liquid phase portion of the working fluid to the vapor region.
