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.

What is claimed is: 
     
         1 . A manufacturing method for a vapor chamber without an injection tube, the steps comprising:
 a) preparing two plates for covering onto each other to form a vapor chamber housing, and injecting a working fluid between the two plates;   b) preparing a sealed space having a refrigeration device installed therein, and 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; and   c) performing evacuation on the sealing space, and sealing perimeters of the two plates.   
     
     
         2 . The manufacturing method for a vapor chamber without an injection tube according to  claim 1 , wherein in step a), any one of the plates is placed on a processing platform flatly first, and an injector filled with the working fluid is used to inject the working fluid into such plate, followed by covering the other plate onto such plate. 
     
     
         3 . The manufacturing method for a vapor chamber without an injection tube according to  claim 2 , wherein the two plates include a supporting structure formed therein. 
     
     
         4 . The manufacturing method for a vapor chamber without an injection tube according to  claim 1 , wherein step a) further includes preparing a supporting structure for installing inside the two plates, and using an injector filled with the working fluid to inject the working fluid onto a surface of the supporting structure, followed by installing the supporting structure inside the two plates. 
     
     
         5 . The manufacturing method for a vapor chamber without an injection tube according to  claim 2 , wherein in step a), a pressing mold is used for pressing onto the other plate. 
     
     
         6 . The manufacturing method for a vapor chamber without an injection tube according to  claim 2 , wherein in step a), a latch is used for clamping and securing the two plates. 
     
     
         7 . The manufacturing method for a vapor chamber without an injection tube according to  claim 1 , wherein step b) is performed inside a vacuum box. 
     
     
         8 . The manufacturing method for a vapor chamber without an injection tube according to  claim 7 , wherein the refrigeration device is a refrigeration disk or freezer disk. 
     
     
         9 . The manufacturing method for a vapor chamber without an injection tube according to  claim 1 , wherein in step c), a welding gun is used to perform sealing of the two plates. 
     
     
         10 . A vapor chamber apparatus without an injection tube, comprising:
 a housing formed by two plates covering onto each other, and the two places both having a protruded accommodating portion and a sealing edge formed to extend along and continuously surround a circumference of the accommodating portion; and   a capillary structure arranged at an inner wall of the accommodating portion of the two plates;   wherein the sealing edge of the two plates are attached onto each other and is continuously surrounded by an outer edge of the two plates and is formed via an edge sealing in order to seal the working fluid inside the accommodating portion of the two plates.   
     
     
         11 . The vapor chamber apparatus without an injection tube according to  claim 10 , wherein the sealing edge of the two plates are completely flat and attached onto each other. 
     
     
         12 . The vapor chamber apparatus without an injection tube according to  claim 10 , wherein the two plates include two through holes respectively formed thereon and corresponding to each other, and an outer of the two through holes is respectively formed of a hole edge for attachment onto each other. 
     
     
         13 . The vapor chamber apparatus without an injection tube according to  claim 12 , wherein any one of the accommodating portions of the plate is indented inward to form an outer hole wall, and the outer hole wall is integrally connected to the hole edge thereof. 
     
     
         14 . The vapor chamber apparatus without an injection tube according to  claim 10 , wherein any one of the accommodating portions of the plate is indented inward to form a blind hole; the blind hole is formed by a bottom edge connected to a circumferential wall outside the bottom edge, and attached onto another plate via the bottom edge.
