Vapor chamber

Abstract

A vapor chamber includes a first board, a second board sealed with the first board, and a cavity formed between the first and second boards, and the cavity contains a first support arm and a second support arm corresponding to the first and second boards respectively, and the first support arm and the second support arm are engaged with each other along the first and second boards and arranged adjacent to each other. With the engagement of the first and second support arms, the first and second boards of the vapor chamber can be supported and pulled to achieve effect of preventing the first and second boards from being recessed or protruded.

1 . A vapor chamber, comprising:
 a first board; and   a second board, sealed with the first board to form a cavity, and the cavity containing an operating fluid therein;   wherein the cavity includes a first support arm and a second support arm installed on the first and second boards respectively, and the first support arm and the second support arm are engaged and arranged adjacent with each other along the first and second boards respectively.   
     
     
         2 . The vapor chamber of  claim 1 , wherein the first and second support arms come with a plurality. 
     
     
         3 . The vapor chamber of  claim 1 , wherein the first and second support arms are installed horizontally in opposite directions and adjacent to each other. 
     
     
         4 . The vapor chamber of  claim 1 , wherein the first and second support arms are installed vertically in alternate directions and adjacent to each other. 
     
     
         5 . The vapor chamber of  claim 1 , wherein the first and second support arms are coupled to bases of the first and second boards respectively, and press portions are transversally protruded from the bases of the first and second support arms respectively, and the press portions of the first and second support arms are disposed alternately and engaged with each other. 
     
     
         6 . The vapor chamber of  claim 5 , wherein the press portion of the first support arm includes a propping surface formed at a position opposite to the second board, and the press portion of the second support arm includes another propping surface formed at a position opposite to the first board. 
     
     
         7 . The vapor chamber of  claim 6 , wherein the press portion of the first support arm includes an embedding surface formed at a position opposite to the first board, and the press portion of the second support arm includes another embedding surface formed at a position opposite to the second board. 
     
     
         8 . The vapor chamber of  claim 7 , wherein the embedding surfaces of the first and second support arms are horizontally and transversally attached to each other. 
     
     
         9 . The vapor chamber of  claim 7 , wherein the embedding surfaces of the first and second support arms are slantingly attached to each other and inwardly tapered. 
     
     
         10 . The vapor chamber of  claim 7 , further comprising a first notch formed between the embedding surface of the first support arm and the first board, and a second notch formed between the embedding surface of the second support arm and the second board, and the press portion of the first support arm is embedded into the second notch, and the press portion of the second support arm is embedded into the first notch for a connection. 
     
     
         11 . The vapor chamber of  claim 10 , wherein the first notch of the first support arm is formed transversally on a side of the first support arm, and the press portion of the second support arm is embedded into the first notch of the first support arm directly for a connection. 
     
     
         12 . The vapor chamber of  claim 1 , further comprising a capillary tissue disposed on an internal wall of the cavity. 
     
     
         13 . The vapor chamber of  claim 12 , wherein the capillary tissue is comprised of a ditch, a mesh or a sintered powder.
