         2 . The method of  claim 1 , wherein sections of the support members are circular or polygonal and sections of the first engaging recesses and the second engaging recesses are circular or polygonal corresponding to the sections of the support members. 
     
     
         3 . The method of  claim 1 , wherein the support members are connected to each other by a connecting structure. 
     
     
         4 . The method of  claim 1 , wherein the first metal cover plate and the second metal cover plate are made of copper or aluminum. 
     
     
         5 . The method of  claim 1 , further comprising:
 forming a capillary structure between 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.   
     
     
         6 . The method of  claim 5 , 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. 
     
     
         7 . A vapor chamber comprising:
 a first metal cover plate having a plurality of first engaging recesses;   a second metal cover plate having a plurality of second engaging recesses;   a plurality of support members, a first end of each support member being riveted into one of the first engaging recesses in a tight-fitting manner and a second end being riveted into one of the second engaging recesses in a tight-fitting manner;   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.   
     
     
         8 . The vapor chamber of  claim 7 , wherein sections of the support member are circular or polygonal and sections of the first engaging recesses and the second engaging recesses are circular or polygonal corresponding to the sections of the support members. 
     
     
         9 . The vapor chamber of  claim 7 , wherein the support members are connected to each other by a connecting structure. 
     
     
         10 . The vapor chamber of  claim 7 , wherein the first metal cover plate and the second metal cover plate are made of copper or aluminum. 
     
     
         11 . The vapor chamber of  claim 10 , 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. 
     
     
         12 . A method of manufacturing a vapor chamber comprising:
 providing a first metal cover plate and a second metal cover plate, wherein the first metal cover plate has a plurality of support members, the first metal cover plate and the support members are formed integrally, the second metal cover plate has a plurality of engaging recesses, a width of a free end of each support member is larger than a width of each engaging recess;   making the free ends of the support members abut against the engaging recesses; and   punching the first metal cover plate and the second metal cover plate so as to rivet the free ends of the support members into the engaging recesses in a tight-fitting manner.   
     
     
         13 . The method of  claim 12 , wherein sections of the support members are circular or polygonal and sections of the engaging recesses are circular or polygonal corresponding to the sections of the support members. 
     
     
         14 . The method of  claim 12 , wherein the first metal cover plate and the second metal cover plate are made of copper or aluminum. 
     
     
         15 . The method of  claim 12 , further comprising:
 forming a capillary structure between 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.   
     
     
         16 . The method of  claim 15 , 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. 
     
     
         17 . A vapor chamber comprising:
