Vapor chamber and supporting structure of the same

Abstract

A vapor chamber includes a casing, the working fluid, a wick structure and a supporting structure. The casing has a hollow room for allowing the working fluid to be filled therein. The wick structure is distributed in the hollow room. The supporting structure abuts against an inside surface of the wick structure. The supporting structure includes side plates and a plurality of wavelike pieces connected between the side plates. Each of the wavelike pieces is constituted of a plurality of crests and troughs. The crests of any two neighboring wavelike pieces are arranged in an alternating manner. A penetrating hole is provided at the crests and the troughs respectively. The working fluid flows through the separated passages and the penetrating holes. Via the above arrangement, the heat-conducting efficiency of the vapor chamber can be enhanced.

1 . A vapor chamber, comprising:
 a casing having a hollow room;   a working fluid filled in the hollow room;   a wick structure distributed in the hollow room; and   a supporting structure abutting against an inside surface of the wick structure, the supporting structure comprising at least two side plates and a plurality of wavelike pieces between the two side plates, each of the wavelike pieces being constituted of a plurality of crests and troughs, the crests of any two neighboring wavelike pieces being arranged in an alternating manner, and a penetrating hole being provided at the crests and the troughs respectively.   
     
     
         2 . The vapor chamber according to  claim 1 , wherein the casing comprises a lower shell and an upper shell for sealing the lower shell, the hollow room is formed between the upper shell and the lower shell. 
     
     
         3 . The vapor chamber according to  claim 2 , wherein the lower shell is constituted of a bottom plate and a plurality of surrounding plates for surrounding the circumference of the bottom plate. 
     
     
         4 . The vapor chamber according to  claim 2 , wherein the wick structure comprises a lower layer and an upper layer connected to the lower layer, the upper layer is adhered to the surface of the upper shell while the lower layer is adhered to the surface of the lower shell. 
     
     
         5 . The vapor chamber according to  claim 1 , wherein the wick structure is a metallic woven mesh. 
     
     
         6 . The vapor chamber according to  claim 1 , wherein any two neighboring wavelike pieces are separated from each other to form a separated passage therebetween. 
     
     
         7 . The vapor chamber according to  claim 1 , wherein the crests are located at positions higher than a top surface of the side plate. 
     
     
         8 . The vapor chamber according to  claim 1 , wherein the troughs are located at positions lower than a bottom surface of the side plate. 
     
     
         9 . The vapor chamber according to  claim 1 , wherein the troughs of any two neighboring wavelike pieces are arranged in an alternating manner. 
     
     
         10 . A supporting structure of a vapor chamber, comprising;
 at least two side plates; and   a plurality of wavelike pieces connected between the two side plates, each of the wavelike pieces being constituted of a plurality of crests and troughs, the crests of any two neighboring wavelike pieces being arranged in an alternating manner, and a penetrating hole being provided at the crests and the troughs respectively.   
     
     
         11 . The supporting structure of a vapor chamber according to  claim 10 , wherein any two neighboring wavelike pieces are separated from each other to form a separated passage therebetween. 
     
     
         12 . The supporting structure of a vapor chamber according to  claim 10 , wherein the crests are located at positions higher than a top surface of the side plate. 
     
     
         13 . The supporting structure of a vapor chamber according to  claim 10 , wherein the troughs are located at positions lower than a bottom surface of the side plate. 
     
     
         14 . The supporting structure of a vapor chamber according to  claim 10 , wherein the troughs of any two neighboring wavelike pieces are arranged in an alternating manner.
