Abstract

A three-dimensional vapor chamber device includes an upper cover, a bottom cover and a porous wick structure. The upper cover includes a tube and a base plate having a base cavity, an opening hole and an upper outer surface. The tube has a top end having a sealed structure and a tubular cavity, and is configured on the upper outer surface, located above the opening hole and extended outwardly. An airtight cavity is formed from the base cavity and the tubular cavity when the bottom cover is sealed to the upper cover. The porous wick structure is continuously disposed on a tubular internal surface, an upper internal surface and a bottom internal surface. Wherein, the sealed structure is formed by pre-setting a liquid injection port at the top end, injecting the working fluid into the airtight cavity through the liquid injection port, and then sealing the liquid injection port.
