Claim Text:
1. A micro vapor chamber, configured to cooperate with at least one heat source and including: a first plate having a first side surface and a second side surface, the first side surface having at least one condensing region, the condensing region having a plurality of first protrusions; and a second plate having a third side surface and a fourth side surface, the third side surface being located to cover the first side surface, the third side surface having a plurality of liquid-collecting regions and at least one evaporating region, the liquid collecting regions being located outside of the evaporating region, the evaporating region and the liquid collecting regions having a plurality of unevenly spaced second protrusions having uniform flat surfaces, the fourth side surface being adhered to the heat source; wherein the condensing region further has a central first condensing portion flanked by sections of a second condensing portion, located on both sides of the central first condensing portion; wherein the central first condensing portion and the sections of the second condensing portion are constituted of said first protrusions; wherein said first protrusions are separated and have a spaced rounded surface giving them a height and the height of the first protrusions in the sections of the second condensing portion gradually increases from outer regions toward the central first condensing portion; wherein the height of the first protrusions in the central first condensing portion is uniform and higher than any of the protrusions in the second condensing portion; and wherein the liquid-collecting regions and the evaporating region have a plurality of channels which are defined by a plurality of second protrusions, wherein one end of each second protrusion is a free end and each second protrusion corresponds to two channels.
