Manufacturing method for vapor chamber without injection tube and apparatus thereof

Abstract

A manufacturing method for a vapor chamber without an injection tube and an apparatus thereof, includes the steps of preparing two plates for covering onto each other to form a vapor chamber housing, injecting a working fluid between the two plates, and further preparing a sealed space having a refrigeration device installed therein, and then placing the two plates having the working fluid injected therein onto the refrigeration device, thereby maintaining a temperature of the working fluid below a boiling point under a vacuum state; next, performing evacuation on the sealing space, and then sealing perimeters of the two plates. Consequently, a vapor chamber without any injection tube can be obtained through such manufacturing method.
