Folding vapor chamber

Abstract

A folding vapor chamber includes folding boards engaged and covered with one another, a folding edge formed between the adjacent folding boards and provided for connecting the folding boards integrally, and the adjacent folding boards being bent and folded by the corresponding folding edge and engaged with one another, and a capillary tissue installed at an internal surface between the folding boards. The casing is formed by the folding edge to reduce the length of the sealing edge of the vapor chamber, so as to achieve the effects of lowering the defective rate of the edge sealing operation, and preventing the sealing edge from being cracked easily.

1 . A folding vapor chamber, comprising:
 a plurality of folding boards;   a folding edge, formed between two adjacent folding boards, for integrally coupling the folding boards, and folding the adjacent folding boards with respect to the folding edge to cover one another; and   a capillary tissue, installed on an internal surface within the folding boards.   
     
     
         2 . The folding vapor chamber of  claim 1 , wherein the casing is comprised of the two corresponding folding boards, and the folding edge is formed at a corresponding position between the two folding boards. 
     
     
         3 . The folding vapor chamber of  claim 1 , wherein the casing is comprised of three folding boards, and one of the folding boards has an area substantially equal to the sum of areas of the other two folding boards, and the folding edge is formed at a corresponding position between the folding boards and provided for the other two folding boards to be folded and covered onto the folding boards with the larger area with respect to the folding edge. 
     
     
         4 . The folding vapor chamber of  claim 1 , wherein each of the folding boards has a sealing edge reserved at the external periphery of each folding board. 
     
     
         5 . The folding vapor chamber of  claim 4 , wherein the sealing edge of any one of the folding boards has an air removing tube. 
     
     
         6 . The folding vapor chamber of  claim 4 , wherein the sealing edge of the folding boards has opposite half-tube portions, and an air removing tube is formed after the half-tube portions are engaged and covered by the folding boards. 
     
     
         7 . The folding vapor chamber of  claim 1 , further comprising a support structure installed between the folding boards. 
     
     
         8 . The folding vapor chamber of  claim 1 , wherein the capillary tissue is comprised of grooves, meshes or sintered powders.
