Abstract:
A vapor chamber heat spreader includes a condenser arranged at a top end of the vapor chamber heat spreader, an evaporator arranged at an opposite end to the condenser; and multi-level wick structures. The multi-level structures include a first planar wick arranged adjacent to the condenser, a second planar wick arranged adjacent to the evaporator, a plurality of condenser posts for supplying liquid condensed by the condenser, a plurality of evaporator posts for supply the liquid towards the evaporator, and a mesh layer. The mesh layer is arranged between the condenser posts and the evaporator posts and configured to separate the condenser posts from the evaporator posts. The mesh layer includes a plurality of vent holes. The mesh layer is a porous layer having high permeability.

Claim (Index 8):
A multi-level wick structure for a vapor chamber heat spreader having a condenser and an evaporator, comprising:\n a first porous layer arranged on a condenser side; a second porous layer arranged on an evaporator side; a first set of porous posts arranged adjacent to the first porous layer; and a second set of porous posts arranged adjacent to the second porous layer; a mesh layer having predetermined permeability and separating the first set of porous posts from the second set of porous posts and configured as a manifold to distribute the condensed liquid to the second set of porous posts, where the mesh layer further comprises a plurality of vent holes that permit vapor to rise towards the condenser side; wherein the first set of porous posts and the second set of porous posts are configured to supply liquid condensed by the condenser from the condenser side to the evaporator side; and wherein the vent holes and the first set of porous posts and the second set of porous posts do not overlap such that:\n the second set of porous posts are spaced apart from each other; \n the vent holes are arranged between two neighboring second set of porous posts; and \n each of the first set of porous posts is arranged between the two neighboring second set of porous posts and between two neighboring vent holes present in the mesh layer.
