Cooling cup

Abstract

A cooling cup includes a cup body, a plurality of heat pipes and a heat sink. The cup body includes a bottom board and a surrounding wall. The surrounding wall is a tubular structure and defines an upper opening and a lower opening. The bottom board envelops the lower opening. Each heat pipe includes an evaporating section and a condensing section. The evaporating section thermally contacts the cup body. The heat sink thermally contacts the condensing section of the heat pipe.

What is claimed is: 
     
         1 . A cooling cup comprising:
 a cup body;   a plurality of heat pipes, each heat pipe comprising an evaporating section and a condensing section, the evaporating section thermally contacting the cup body, and the condensing section thermally contacting a heat sink.   
     
     
         2 . The cooling cup of  claim 1 , wherein the cup body comprises a bottom board and a surrounding wall, the surrounding wall is a tubular structure and defines an upper opening and a lower opening, and the bottom board envelops the lower opening. 
     
     
         3 . The cooling cup of  claim 2 , wherein the bottom board is a curved structure. 
     
     
         4 . The cooling cup of  claim 3 , wherein the bottom board protrudes downwardly from the lower opening of the surrounding wall. 
     
     
         5 . The cooling cup of  claim 1 , wherein the cup body comprises an inner surface, and a corrosion protecting layer is formed on the inner surface. 
     
     
         6 . The cooling cup of  claim 2 , wherein the evaporating section extends from the upper opening of the cup body downwards toward the lower opening perpendicularly, and extends from the lower opening to the bottom board. 
     
     
         7 . The cooling cup of  claim 1 , wherein the cup body comprises an outer surface, the evaporating section is attached on the outer surface. 
     
     
         8 . The cooling cup of  claim 7 , wherein the evaporating is buried in the outer surface of the cup body. 
     
     
         9 . The cooling cup of  claim 7 , wherein the evaporating section is a flat shaped structure. 
     
     
         10 . The cooling cup of  claim 1 , further comprising a thermal conductivity material sandwiched between the cup body and the evaporating section. 
     
     
         11 . The cooling cup of  claim 1 , wherein the condensing section extends from an end of the evaporating section along a direction away from the cup body. 
     
     
         12 . The cooling cup of  claim 1 , wherein the condensing section is a cylinder-shaped structure. 
     
     
         13 . The cooling cup of  claim 2 , wherein the heat sink comprises a cooling body, a plurality of contacting portions are defined on the cooling body, the condensing section of the heat pipe thermally contacts the contacting portion. 
     
     
         14 . The cooling cup of  claim 13 , wherein the number of the contacting portions is equal to the number of the heat pipes. 
     
     
         15 . The cooling cup of  claim 13 , wherein the heat sink further comprises a plurality of fins, the fins are formed around the cooling body, and the fins are spaced from each other. 
     
     
         16 . The cooling cup of  claim 15  further comprises a shell, wherein the shell covers the cup body and the heat pipe. 
     
     
         17 . The cooling cup of  claim 15 , wherein a plurality of through holes are formed around the shell, and the holes are adjacent to the lower opening to expose the fins therethrough.
