Title: Thin, planar heat spreader

Abstract: A heat spreading apparatus includes a first planar body for attachment to a heat generating surface which results in a hot region and a cool region on the first planar body. A second planar body connected to the first planar body is used to define a void between the first planar body and the second planar body. The void includes a planar capillary path and a non-capillary region. A fluid positioned within the void distributes heat by vaporizing the fluid from the planar capillary path in the hot region, condensing the fluid in the non-capillary region in the cool region, and moving from the non-capillary region to the planar capillary path in the hot region through capillarity.
