Portable heat sink

Abstract

A heat sink comprises a food-safe structure having an inner surface and an outer surface defining a cavity in which there is a material with a high enthalpy of fusion. A cap sanitarily encloses the material within the cavity.

I claim: 
     
         1 . A heat sink device, comprising:
 a food-safe structure having an inner surface and an outer surface defining a cavity in which there is a material with a high enthalpy of fusion; and   a cap sanitarily enclosing the material within the cavity.   
     
     
         2 . The heat sink of  claim 1 , where in the structure comprises a conical shape. 
     
     
         3 . The heat sink of  claim 1 , where in the structure comprises a ovular shape. 
     
     
         4 . The heat sink of  claim 1 , where in the structure comprises a spherical shape. 
     
     
         5 . The heat sink of  claim 1 , further comprising at least one fin about the outer surface. 
     
     
         6 . The heat sink of  claim 5 , wherein the at least one fin goes about the circumference of the outer surface of the structure. 
     
     
         7 . The heat sink of  claim 6 , wherein the at least one fin spirals about the outer surface of the structure. 
     
     
         8 . The heat sink of  claim 5 , comprising one fin about the outer surface. 
     
     
         9 . The heat sink of  claim 1 , wherein the structure is made from stainless steel. 
     
     
         10 . The heat sink of  claim 1 , wherein the material comprises water.
