Heat pipe type heat sink and method of manufacturing the same

Abstract

A heat pipe type heat sink ( 1 ) and method of manufacturing the same are disclosed. The heat pipe type heat sink ( 1 ) includes a plurality of heat pipes ( 11 ) and a base ( 12 ) supporting the heat pipes. Each of the heat pipes ( 11 ) has a heat absorption portion ( 111 ) and a heat dissipation portion ( 112 ) in connection with the heat absorption portion ( 111 ). One side of the base ( 12 ) is provided with a plurality of grooves ( 121 ). The heat absorption portion ( 111 ) of the heat pipe ( 12 ) is pressed and held in a respective one of the grooves ( 121 ).

1 . A heat pipe type heat sink comprising:
 a plurality of heat pipes each having a heat absorption portion and a heat dissipation portion in connection with the heat absorption portion; and   a base supporting the plurality of heat pipes,   wherein a side of the base is provided with a plurality of grooves, at least a portion of the heat absorption portion is disposed within a respective one of the plurality of grooves, and   the heat absorption portion is pressed so that the heat absorption portion is deformed and held in the respective one of the plurality of grooves.   
     
     
         2 . The heat pipe type heat sink of  claim 1 , wherein the plurality of grooves are disposed on a bottom surface of the base, the heat absorption portion has a pressed flat surface arranged flush with the bottom surface of the base and serving as a heat absorption surface. 
     
     
         3 . The heat pipe type heat sink of  claim 1 , wherein the base is a plate shaped block, and the plurality of grooves are longitudinally arranged on a side of the block, and extend transversely across the side of the block. 
     
     
         4 . The heat pipe type heat sink of  claim 1 , wherein each of the plurality of grooves has an opening of gradually narrowed shape, and a protruded portion of the heat absorption portion which protrudes from the groove is pressed so that the heat absorption portion is deformed and held in the groove. 
     
     
         5 . The heat pipe type heat sink of  claim 1 , wherein a heat-conducting medium is further arranged between the respective one of the plurality of grooves and the heat absorption portion. 
     
     
         6 . The heat pipe type heat sink of  claim 1 , wherein the plurality of heat pipes are of U shape or L shape. 
     
     
         7 . A method of manufacturing a heat pipe type heat sink, comprising:
 providing a heat pipe with a heat absorption portion and a heat dissipation portion in connection with the heat absorption portion, and a base with a groove defined on a side thereof,   pressing the heat absorption portion of the heat pipe to deform and hold the heat absorption portion in the groove.   
     
     
         8 . The method of  claim 7 , wherein in the step of pressing the heat absorption portion, a part of the heat absorption portion of the heat pipe is placed in the groove of the base, and a protruded portion of the heat absorption portion which protrudes from the groove is pressed so that the heat absorption portion is deformed and held in the groove. 
     
     
         9 . The method of  claim 8 , wherein in the step of pressing the heat absorption portion, the heat absorption portion is pressed to form a pressed flat surface serving as a heat absorption surface. 
     
     
         10 . The method of  claim 8 , wherein in the step of pressing the heat absorption portion, the heat absorption portion of the heat pipe is pressed to form a pressed flat surface arranged flush with a bottom surface of the base.
