Supporting structure with height difference and vapor chamber having the supporting structure

Abstract

A vapor chamber having supporting structure with height difference, includes a shell, tissue wick structure, working fluid filled into the shell and supporting structure with height difference, disposed over inner walls of the shell, accommodated in the shell, abutted against the wick structure, and including first corrugated piece and second corrugated piece, both of which are connected to each other. The longitudinal distance between top and bottom of the first corrugated piece is a first amplitude. The longitudinal distance between top and bottom of the second corrugated piece is a second amplitude larger than the first amplitude. Since the second amplitude provides the shell with greater supporting force, when the shell is pressed to make heating element and the shell contact closely, a recessing phenomenon won't occur to the shell, thereby, increasing the contact tightness and promoting the thermally conductive efficiency.

1 . A vapor chamber having supporting structure with height difference, including:
 a shell;   a wick structure disposed over inner walls of the shell;   a working fluid filled into the shell; and   a supporting structure with height difference, which is accommodated in the shell and is abutted against the wick structure, and which includes:
 a first corrugated piece, a longitudinal distance between a top and a bottom of which is a first amplitude; and 
 a second corrugated piece, which is connected to the first corrugated piece, and a longitudinal distance between a top and a bottom of which is a second amplitude, which is larger than the first amplitude. 
   
     
     
         2 . The vapor chamber having supporting structure with height difference according to  claim 1 , wherein the first corrugated piece is arranged a through opening, in which the second corrugated piece is accommodated. 
     
     
         3 . The vapor chamber having supporting structure with height difference according to  claim 2 , wherein wave forms of the first corrugated piece and the second corrugated piece are both a sine wave. 
     
     
         4 . The vapor chamber having supporting structure with height difference according to  claim 3 , wherein the first corrugated piece has a hole, into which a pin formed at one end of the second corrugated piece is inset. 
     
     
         5 . A supporting structure with height difference, including:
 a first corrugated piece, a longitudinal distance between a top and a bottom of which is a first amplitude; and   a second corrugated piece connected to the first corrugated piece, and a longitudinal distance between a top and a bottom of which is a second amplitude larger than the first amplitude.   
     
     
         6 . The vapor chamber having supporting structure with height difference according to  claim 5 , wherein the first corrugated piece is arranged a through opening, in which the second corrugated piece is accommodated. 
     
     
         7 . The vapor chamber having supporting structure with height difference according to  claim 6 , wherein wave forms of the first corrugated piece and the second corrugated piece are both a sine wave. 
     
     
         8 . The vapor chamber having supporting structure with height difference according to  claim 7 , wherein the first corrugated piece has a hole, into which a pin formed at one end of the second corrugated piece is inset.
