Abstract: A 3D vapor chamber includes a vapor chamber and at least one pipe body. The vapor chamber has an upper plate and a lower plate mated with each other. The upper plate is formed with at least one perforation. An open end of the pipe body is outward expanded to form a lip section in connection with the upper plate. A closed end of the pipe body passes through the perforation of the upper plate. The closed end and the open end together define a tubular chamber in communication with the open end and the vapor chamber. Multiple channels formed on an inner side of the tubular chamber and an inner side of the lip section are in contact and connect with a capillary structure of the inner side of the upper plate so as to increase back flowing speed of a working fluid and enhance heat dissipation performance.
