         3 . The vapor chamber of  claim 2 , wherein the side wall extends vertically from periphery edge of the condensation surface away from the condensation board. 
     
     
         4 . The vapor chamber of  claim 3 , wherein each isolation board extends from the condensation surface of the condensation board away from the condensation board. 
     
     
         5 . The vapor chamber of  claim 4 , wherein a height of the isolation boards is equal to a depth of the groove. 
     
     
         6 . The vapor chamber of  claim 2 , wherein the vapor chamber comprises two isolation boards, the two isolation boards are perpendicular to each other. 
     
     
         7 . The vapor chamber of  claim 6 , wherein the isolation boards have the same extending direction with the side wall of the condensation board. 
     
     
         8 . The vapor chamber of  claim 7 , wherein each isolation board is contacted with and perpendicular to the side wall of the condensation board. 
     
     
         9 . The vapor chamber of  claim 8 , wherein each cavity is enclosed by the isolation boards and the side wall, at least one side surface of the cavity is the side wall of the condensation board. 
     
     
         10 . The vapor chamber of  claim 9 , wherein two adjacent sides of each cavity are part of the two isolation boards and the other two adjacent sides of the cavity are the side wall of the condensation board. 
     
     
         11 . The vapor chamber of  claim 9 , wherein a filling hole is defined on the side wall of a corresponding cavity. 
     
     
         12 . The vapor chamber of  claim 11 , wherein the filling holes are symmetrically defined on the two opposite ends of the side wall of the condensation board.
