Refrigerator having heat conduction sheet

Abstract

A refrigerator having one or more heat conduction sheets is provided. The refrigerator may include main body having a cooling chamber formed therein, and a door that opens and closes the cooling chamber. One or more heat conduction sheets may be disposed on the main body, the door, or a combination of various portions thereof so as to substantially eliminate an occurrence of a temperature variation on a corresponding planar surface and reduce an insulation thickness.

         8 . The refrigerator of  claim 7 , wherein the main body comprises an inner case positioned within an outer case, with a space formed therebetween, and wherein the at least one heat conduction sheet is positioned on an inner surface of the outer case. 
     
     
         9 . The refrigerator of  claim 7 , wherein the at least one heat conduction sheet is attached to an outer surface of the at least one side wall duct. 
     
     
         10 . The refrigerator of  claim 1 , further comprising at least one side wall duct provided at a side wall of the cooling chamber, wherein the at least one heat conduction sheet is provided is attached to an inner surface of the at least one side wall duct. 
     
     
         11 . The refrigerator of  claim 1 , wherein the at least one heat conduction sheet conducts heat in a planar direction thereof such that a surface temperature of the at least one of the main body or the door on which the at least one heat conduction sheet is provided is substantially uniform. 
     
     
         12 . The refrigerator of  claim 1 , wherein the at least one heat conduction sheet is formed of graphite, a metallic member or a heat conductive plastic. 
     
     
         13 . The refrigerator of  claim 1 , further comprising a partition wall that separates the cooling chamber from a compartment formed within the main body that houses an evaporator, wherein the at least one heat conduction sheet comprises a first heat conduction sheet provided on the partition wall. 
     
     
         14 . The refrigerator of  claim 13 , wherein the first heat conduction sheet is formed of graphite, a metallic material or a heat conductive plastic. 
     
     
         15 . The refrigerator of  claim 13 , wherein the at least one heat conduction sheet further comprises a second heat conduction sheet installed on the ice making chamber door. 
     
     
         16 . The refrigerator of  claim 15 , further comprising at least one side wall duct provided at a side wall of the cooling chamber, and wherein the at least one heat conduction sheet further comprises a third heat conduction sheet installed at an outside of the at least one side wall duct. 
     
     
         17 . The refrigerator of  claim 16 , wherein the third heat conduction sheet is installed on an inner surface of an outer case of the main body, spaced apart from the at least one side wall duct. 
     
     
         18 . The refrigerator of  claim 16 , wherein the third heat conduction sheet is positioned on an outer wall surface of the at least one side wall duct.
