Heat dissipating assembly with heat pipes

Abstract

A heat dissipation assembly includes a base, plural of fins and two heat pipes. The base includes a body and two heat-conducting portions extending slantwise from two sides of the body. A void is defined in the base surrounded by the body and the heat-conducting portions. Two grooves are defined in an upper surface of the body. The fins are attached on the heat-conducting portions. A through hole is defined in each of two sides of each fin. One end of each heat pipe is securely received in the groove of the body and the other end of each heat pipe is extended through the holes of the fins, for transferring heat from the body to the fins effectively.

1 . A heat dissipating assembly comprising: 
 plural of fins cooperatively defining a space;    a base located in the space, a void defined in the base; and    at least a heat pipe, one end of the at least a heat pipe received in the base, an opposite end of the at least a heat pipe extending through the fins.    
   
   
       2 . The heat dissipating assembly as described in  claim 1 , wherein each fin defines a cutout in a bottom thereof to cooperatively define the space.  
   
   
       3 . The heat dissipating assembly as described in  claim 1 , wherein the base defines at least a groove communicating with the void, said one end of the at least a heat pipe being received in the at least a groove.  
   
   
       4 . The heat dissipating assembly as described in  claim 3 , wherein the base comprises a body and two heat-conducting portions extending from the body, said void being defined between the body and the heat-conducting portions.  
   
   
       5 . The heat dissipating assembly as described in  claim 4 , wherein the two heat-conducting portions extend slantwise from two sides of the body.  
   
   
       6 . The heat dissipating assembly as described in  claim 5 , wherein the fins comprise a plurality of hems formed on opposite side of the space and attached on the heat-conducting portions.  
   
   
       7 . The heat dissipating assembly as described in  claim 4 , wherein an airflow channel is defined between top ends of the two heat-conducting portions to allow cooling air to enter into the void.  
   
   
       8 . The heat dissipating assembly as described in  claim 1 , wherein each fin defines at least a through hole for extension of the at least a heat pipe.  
   
   
       9 . A heat dissipating assembly, comprising: 
 a base defining a void therein and at least a groove communicating with the void;    plural of fins arranged on the base; and    at least a heat pipe, one end of the at least a heat pipe received in the groove of the base, an opposite end of the at least a heat pipe extending through the fins.    
   
   
       10 . The heat dissipating assembly as described in  claim 9 , wherein the base comprises a body and two heat-conducting portions extending from the body, said void being defined between the body and the heat-conducting portions.  
   
   
       11 . The heat dissipating assembly as described in  claim 10 , wherein the groove is defined in an upper surface of the body.  
   
   
       12 . The heat dissipating assembly as described in  claim 10 , wherein the fins are attached on the heat-conducting portions.  
   
   
       13 . The heat dissipating assembly as described in  claim 10 , wherein the two heat-conducting portions extend slantwise from two sides of the body.  
   
   
       14 . The heat dissipating assembly as described in  claim 10 , wherein an airflow channel is defined between top ends of the two heat-conducting portions.  
   
   
       15 . The heat dissipating assembly as described in  claim 9 , wherein each fin defines at least a through hole for extension of the at least a heat pipe.  
   
   
       16 . A heat dissipation assembly comprising: 
 a fin assembly including a plurality of spaced parallel fins cooperatively defining a space in one side face of said fin assembly;    a base configured to be snugly received in the space;    a void defined in said base with an opening for ventilating communication with a fan which is located on another side face of the fin assembly; and    a heat pipe defining a section which is attached to said base and exposed to said void.    
   
   
       17 . The heat dissipation assembly as described in  claim 16 , wherein an opposite section of the heat pipe extends through said fin assembly in a perpendicular manner.  
   
   
       18 . The heat dissipation assembly as described in  claim 16 , wherein said base is of a triangular configuration with said opening at the uppermost apex.
