Abstract
The vapor chamber includes a casing, wick structure, working fluid and filling/degassing tube. The casing is composed of two plates and has a chamber therein. The wick structure and working fluid are disposed in the chamber. The filling/degassing tube is connected with the casing to form a passage communicating with the chamber. A portion of the plates which overlaps the filling/degassing tube is pressed to deform for making the passage closed. And the outer end of the filling/degassing tube is flush with the side of the casing.
