The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A flat-plate heat spreader for a heat generating device, comprising: an enclosed metal chamber, to be in contact with said heat generating device; a two-phase vaporizable coolant recycled in said chamber to remove heat from said heat generating device; a flow path comprising an upper section and a lower section, said upper section being in contact with the inner top wail of said chamber for vapor condensation and heat dissipation, said upper section having a set of grooves as vapor passage, with groove walls made of non-porous metal, in contact with said lower section, said lower section functioning as part of a recycling passage for the condensed coolant; and a wick in said lower section, a portion of said wick functioning as an evaporator and the other portion of said wick functioning as a liquid passage to draw said condensed coolant from said upper section through the walls of said grooves by capillary attraction force, said coolant collected within said evaporator waiting to be vaporized by the heat from said heat generating device; and a plurality of cut-off openings on said groove walls located over said wick covering at least the area in contact with said heat generating device to allow said coolant vapor to diffuse into said grooves to be condensed therein on said groove walls and in groove corners, said condensed coolant can flow along said groove corners by capillary force therein.
2. The heat spreader as described in claim 1, wherein said grooves have a cross-section selected from the group consisting of: V-shaped, triangular, rectangular, trapezoidal, and arc-shaped.
3. The heat spreader as described in claim 1, wherein said set of grooves are parallel grooves.
4. The heat spreader as described in claim 1, wherein said set of grooves are of a branching pattern.
5. The heat spreader as described in claim 1, wherein said groove walls are made of a metal material.
6. The heat spreader as described in claim 1, wherein said groove walls are made of a non-metal material.
7. The heat spreader as described in claim 5, wherein said groove walls are integrated with the top of said chamber as a unitary cover.
