Vapor chamber and method of manufacturing the same

Abstract

A method of manufacturing a vapor chamber includes steps of: attaching a first edge of a first metal cover plate to a second edge of a second metal cover plate; placing the first metal cover plate and the second metal cover plate on a die after attachment; and using a punch head to punch the first edge and the second edge in a direction toward the die so as to seal the first edge and the second edge.

What is claimed is: 
     
         1 . A method of manufacturing a vapor chamber comprising:
 attaching a first edge of a first metal cover plate to a second edge of a second metal cover plate;   placing the first metal cover plate and the second metal cover plate on a die after attachment; and   using a punch head to punch the first edge and the second edge in a direction toward the die so as to seal the first edge and the second edge.   
     
     
         2 . The method of  claim 1 , further comprising:
 cutting a material form an end of the first edge and the second edge while the punch head punches the first edge and the second edge.   
     
     
         3 . The method of  claim 1 , wherein at least one of the first edge and the second edge has a rough surface structure before being punched. 
     
     
         4 . The method of  claim 1 , further comprising:
 using a fastener to clamp the first edge and the second edge, which have been sealed.   
     
     
         5 . The method of  claim 1 , wherein the first metal cover plate and the second metal cover plate are made of copper or aluminum. 
     
     
         6 . The method of  claim 1 , further comprising:
 forming a capillary structure between the first metal cover plate and the second metal cover plate;   disposing a plurality of support members between the first metal cover plate and the second metal cover plate so as to support the first metal cover plate and the second metal cover plate; and   filling a working fluid in between the first metal cover plate and the second metal cover plate.   
     
     
         7 . The method of  claim 6 , wherein the capillary structure is a groove-type capillary structure, a porous capillary structure, a mesh capillary structure, a sintered capillary structure or a compound capillary structure. 
     
     
         8 . A vapor chamber comprising:
 a first metal cover plate;   a second metal cover plate, a first edge of the first metal cover plate and a second edge of the second metal cover plate being sealed by the method of  claim 1  through a punch process;   a capillary structure formed between the first metal cover plate and the second metal cover plate; and   a working fluid filled in between the first metal cover plate and the second metal cover plate.   
     
     
         9 . The vapor chamber of  claim 8 , further comprising a plurality of support members disposed between the first metal cover plate and the second metal cover plate so as to support the first metal cover plate and the second metal cover plate. 
     
     
         10 . The vapor chamber of  claim 8 , further comprising a fastener for clamping the first edge and the second edge, which have been sealed. 
     
     
         11 . The vapor chamber of  claim 8 , wherein the first metal cover plate and the second metal cover plate are made of copper or aluminum. 
     
     
         12 . The vapor chamber of  claim 8 , wherein the capillary structure is a groove-type capillary structure, a porous capillary structure, a mesh capillary structure, a sintered capillary structure or a compound capillary structure.
