Heat dissipation apparatus with heat pipe

Abstract

A heat dissipation apparatus includes an evaporator receiving heat from a heat source, a condenser releasing the heat of the heat source, and a pipeline inter connecting the evaporator and the condenser. The condenser defines a flat rectangular chamber therein. A working fluid is contained in the evaporator. The working fluid vaporizes upon receiving the heat of the heat source. The pipeline conducts the vaporized working fluid from the evaporator to the condenser. The vaporized working fluid condenses upon releasing the heat in the chamber.

1 . A heat dissipation apparatus, comprising:
 an evaporator receiving heat from a heat source;   a working fluid contained in the evaporator and vaporizing upon receiving heat from the heat source;   a condenser releasing the heat of the heat source, and defining a flat rectangular chamber therein; and   a pipeline interconnecting the evaporator and the condenser, and conducting the vaporized working fluid from the evaporator to the condenser, the vaporized working fluid condensing upon releasing the heat in the chamber.   
     
     
         2 . The heat dissipation apparatus of  claim 1 , wherein the condenser comprises a first cap and a second cap connected with each other to form the condenser. 
     
     
         3 . The heat dissipation apparatus of  claim 1 , wherein a plurality of supporting posts are provided in the condenser, the supporting posts providing support between the first cap and the second cap to maintain the chamber therebetween. 
     
     
         4 . The heat dissipation apparatus of  claim 1 , wherein the evaporator, the pipeline and the condenser are each provided with a wick structure on an inner wall thereof. 
     
     
         5 . The heat dissipation apparatus of  claim 4 , wherein the pipeline defines a vapor passage therein along an axial direction thereof, communicating a chamber of the evaporator with the chamber of the condenser. 
     
     
         6 . The heat dissipation apparatus of  claim 5 , further comprising another pipeline communicating the chamber of the evaporator with the chamber of the condenser to form a loop in cooperation with the pipeline. 
     
     
         7 . The heat dissipation apparatus of  claim 1 , wherein the condenser has an elongated profile. 
     
     
         8 . The heat dissipation apparatus of  claim 1 , wherein the evaporator comprises a flat rectangular casing, and the chamber of the evaporator is a flat rectangular chamber receiving the working fluid. 
     
     
         9 . The heat dissipation apparatus of  claim 1 , further comprising at least one heat sink attached on the condenser. 
     
     
         10 . The heat dissipation apparatus of  claim 9 , wherein the at least one heat sink comprises two heat sinks respectively attached to top and bottom sides of the condenser. 
     
     
         11 . The heat dissipation apparatus of  claim 9 , wherein the at least one heat sink comprises a base plate attached to the condenser and a plurality of fins extending from the base plate.
