Sheet-shaped heat pipe

Abstract

A sheet-shaped heat pipe includes a sheet-shaped container, a wick sealed in the container, and a working fluid sealed in the container, wherein the sheet-shaped container includes a first metal sheet and a second metal sheet, the first metal sheet and the second metal sheet are superposed and at least partially bonded to provide a closed internal space therebetween, and a thickness of the sheet-shaped container is about 0.5 mm or less.

What is claimed is: 
     
         1 . A thin heat dissipating plate comprising:
 a metal plate; and   a sheet-shaped heat pipe disposed on the metal plate; wherein   the metal plate includes a recess;   the sheet-shaped heat pipe includes:
 a sheet-shaped container; 
 a wick sealed in the container; and 
 a working fluid sealed in the container; 
   the sheet-shaped container includes a first metal sheet and a second metal sheet;   the first metal sheet and the second metal sheet have different thicknesses from each other;   the first metal sheet and the second metal sheet are superposed and at least partially bonded to provide a closed internal space therebetween; and   the sheet-shaped heat pipe is disposed in the recess.   
     
     
         2 . The thin heat dissipating plate according to  claim 1 , wherein a thickness of the first metal sheet is larger than a thickness of the second metal sheet. 
     
     
         3 . The thin heat dissipating plate according to  claim 1 , wherein a thickness of the second metal sheet is larger than a thickness of the first metal sheet. 
     
     
         4 . The thin heat dissipating plate according to  claim 1 , wherein the metal sheet and the sheet-shaped heat pipe are bonded. 
     
     
         5 . The thin heat dissipating plate according to  claim 1 , wherein the metal sheet and the sheet-shaped heat pipe are bonded with at least one of solder, a conductive adhesive, and a thermal conductive tape. 
     
     
         6 . The thin heat dissipating plate according to  claim 1 , wherein the metal sheet and the sheet-shaped heat pipe are mechanically fixed. 
     
     
         7 . The thin heat dissipating plate according to  claim 1 , wherein the metal sheet and the sheet-shaped heat pipe are mechanically fixed by at least one of screw holes and claws. 
     
     
         8 . The thin heat dissipating plate according to  claim 1 , wherein a thickness of the sheet-shaped container is about 0.5 mm or less. 
     
     
         9 . The thin heat dissipating plate according to  claim 1 , wherein at least one of the first metal sheet and the second metal sheet includes a thick portion. 
     
     
         10 . The thin heat dissipating plate according to  claim 1 , wherein each of the first metal sheet and the second metal sheet includes a thick portion.
