Vapor chamber with integrally formed wick structure and method of manufacturing same

Abstract

A vapor chamber includes a main body and a wick structure. The main body includes a first and a second plate, which are closed to each other to define a chamber therein between. A working fluid is filled in the chamber. The wick structure is integrally formed on two facing inner surfaces of the first and the second plate by way of mechanical processing, and is projected from the first and second plates toward a central space in the chamber. By integrally forming the wick structure on the first and second plates, the vapor chamber can be manufactured at reduced time and labor to obtain increased yield. A method of manufacturing vapor chamber with integrally formed wick structure is also disclosed.

What is claimed is: 
     
         1 . A vapor chamber with integrally formed wick structure, comprising:
 a main body including a first plate and a second plate; the first plate and the second plate being closed to each other, so as to define a chamber therein between; and the chamber being filled with a working fluid; and   a wick structure being formed on two facing inner surfaces of the first and the second plate to project from the first and the second plate toward a central space in the chamber.   
     
     
         2 . The vapor chamber with integrally formed wick structure as claimed in  claim 1 , further comprising at least one supporting structure; the supporting structure being formed on the inner surface of one of the first and the second plate having the wick structure formed thereon. 
     
     
         3 . The vapor chamber with integrally formed wick structure as claimed in  claim 1 , further comprising a plurality of supporting structures; the supporting structures being formed on the two facing inner surfaces of the first and the second plate having the wick structure formed thereon. 
     
     
         4 . The vapor chamber with integrally formed wick structure as claimed in  claim 1 , wherein the first plate is provided on an outer surface with a    
     
     
         5 . The vapor chamber with integrally formed wick structure as claimed in  claim 2 , wherein the first plate is provided on an outer surface with a radiating fin unit; and the radiating fin unit including a plurality of radiating fins outward extended from the outer surface of the first plate. 
     
     
         6 . The vapor chamber with integrally formed wick structure as claimed in  claim 3 , wherein the first plate is provided on an outer surface with a radiating fin unit; and the radiating fin unit including a plurality of radiating fins outward extended from the outer surface of the first plate. 
     
     
         7 . The vapor chamber with integrally formed wick structure as claimed in  claim 1 , wherein the wick structure is integrally formed on the two facing inner surfaces of the first and the second plate. 
     
     
         8 . The vapor chamber with integrally formed wick structure as claimed in  claim 1 , wherein the wick structure is selected from the group consisting of grooves, roughened surfaces, and grids. 
     
     
         9 . A method of manufacturing vapor chamber with integrally formed wick structure, comprising the following steps:
 providing a first and a second plate;   forming a wick structure on two facing inner surfaces of the first and the second plate by way of mechanical processing; and   closing the first and the second plate to each other to thereby define a chamber therein between; evacuating the chamber, filling the chamber with a working fluid, and sealing the chamber.   
     
     
         10 . The method of manufacturing vapor chamber with integrally formed wick structure as claimed in  claim 9 , further comprising a step after the step of providing the first and the second plate to mechanically process an inner surface of one of the first and the second plate, so as to form at least one supporting structure on the inner surface. 
     
     
         11 . The method of manufacturing vapor chamber with integrally formed wick structure as claimed in  claim 9 , further comprising a step after the step of providing the first and the second plate to mechanically process two facing inner surfaces of the first and the second plate, so as to form a plurality of supporting structures on the two facing inner surfaces. 
     
     
         12 . The method of manufacturing vapor chamber with integrally formed wick structure as claimed in  claim 9 , wherein the wick structure is selected from the group consisting of grooves, roughened surfaces, and grids. 
     
     
         13 . The method of manufacturing vapor chamber with integrally formed wick structure as claimed in  claim 9 , wherein the mechanical processing is selected from the group consisting of stamping, rolling, slotting and milling.
