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 13):
A vapor chamber heat spreader, comprising:\n a condenser arranged at a first end of the vapor chamber heat spreader; an evaporator arranged at a second end of the vapor chamber heat spreader, wherein the second end is opposite to the first end; and multi-level wick structures comprising a first liquid flow channel including a plurality of condenser posts, a second liquid flow channel including a plurality of evaporator posts, and a vapor flow channel including a plurality of vent holes; wherein the first liquid flow channel includes a lateral movement of liquid condensed by the condenser from the condenser to the evaporator, and the second liquid flow channel includes a downward movement of the liquid from the condenser to the evaporator in a hot spot area, where the second liquid flow channel provides a shorter liquid flow path than a liquid flow path provided by the first liquid flow path; wherein the vapor flow channel includes an upward movement of vapor from the evaporator to the condenser and the vapor flow path does not overlap with the second liquid flow path in the hot spot area; wherein the vent holes and the condenser posts and the evaporator posts do not overlap such that:\n the evaporating posts are spaced apart from each other; \n the vent holes are arranged between two neighboring evaporator posts; and \n each condenser post is arranged between the two neighboring evaporator posts and between two neighboring vent holes present in the mesh layer.
