Abstract: A vapor chamber having a first plate, a second plate and a brazing structure is provided. The first plate has an outer surface and an inner surface. A periphery of the first plate has a sealing edge extending outwardly; a level difference exists between the first plate and the sealing edge. Multiple supporting portions are formed on the inner surface of the first plate. The second plate also has an outer surface and an inner surface spaced apart from the inner surface of the first plate, and the second plate covers the first plate to enclose a chamber. The brazing structure has a sealing portion and a plurality of connecting portions, the sealing portion is fixed between the second plate and the sealing edges of the first plate, and the connecting portions are respectively disposed between the corresponding supporting portions of the first plate and of the second plate.

Abstract: A metal mesh includes a plurality of metal wires, a plurality of protrusions, and a plurality of concave portions. The metal wires, which are interlaced with each other to form a mesh, have an outer peripheral reference surface. Each protrusion is protruded from the outer peripheral reference surface of the metal wire. Each concave portion is concaved from the outer peripheral reference surface of the metal wire. Each protrusion is adjacent to at least one recess. Wherein bottom surfaces of the concave portion are non-planar.
