Abstract: A thin vapor chamber includes a heat conducting plate having an upper surface, a metal cover sealed and covering on the heat conducting plate, and a wick structure disposed between the heat conducting plate and the metal cover. A plurality of hollow supports are formed on the metal cover by pressing and face the heat conducting plate. The wick structure is provided with plural throughholes. The hollow supports are individually disposed through the corresponding throughholes and attached to the upper surface. Thus, the heat of the heat conducting plate is transferred to the metal cover through the hollow supports. Besides, the metal cover is pressed to have an uneven shape to increase heat-dissipating area and structural strength, which achieves excellent heat transfer efficiency and heat diffusion of the thin vapor chamber.

Trenches are formed on one side surface of the metal plate. The upper board and the lower board overlap each other to make the corresponding side surfaces of the two metal plates contact each other. The trenches of the two metal plates are correspondingly disposed to form passages. The trenches of one of the metal plates are staggered from the trenches of the other metal plate by an offset distance to form staggered passages. Therefore, the capillary force during reverse flow of a working fluid is enhanced, the contact area between the vapor and the passage is increased, and the heat transfer efficiency of the vapor chamber is improved.
