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.

[ What is claimed is:] [1.] A heat spreading apparatus, comprising:a first planar body for attachment to a heat generating surface which produces a hot region and a cool region on said first planar body;a second planar body connected to said first planar body to define a void between said first planar body and said second planar body, said void including a non-capillary region with a first vertical height to facilitate vapor transport and a planar capillary region with a second vertical height, less than said first vertical height to facilitate capillary fluid motion, said planar capillary region having a substantially rectangular cross-section; anda fluid positioned within said void for distributing heat by vaporizing said fluid from said planar capillary region in said hot region, condensing said fluid in said non-capillary region in said cool region, and moving from said non-capillary region to said planar capillary region in said hot region through capillarity.
