Heat sink structure embedded with heat pipes

Abstract

A heat sink structure embedded with a heat pipe includes a heat dissipation seat, at least one heat pipe, a metal-filling adhesive and at least one covering sheet. The heat dissipation seat has a heat absorption surface and a heat dissipation surface. The heat absorption surface has at least one groove to hold the heat pipe and a bonding medium. The groove is covered by the covering sheet. The metal-filling adhesive is filled with the groove to bond the heat pipe and covering sheet through the bonding medium that can increase adhesion force. The covering sheet covers the heat pipe from being damaged during polishing the heat absorption surface to maintain sealing characteristic of the heat pipe. Therefore, the heat pipe can provide rapid heat conduction effect to meet use requirement.

What is claimed is: 
     
         1 . A heat sink structure embedded with a heat pipe, comprising:
 a heat dissipation seat which includes a heat absorption surface and a heat dissipation surface, the heat absorption surface being caved to form at least one groove to hold a bonding medium;   at least one heat pipe held in the groove;   at least one covering sheet to cover the corresponding groove; and   a metal-filling adhesive filled with the groove to bond the heat pipe and the covering sheet through the bonding medium which increases adhesion force.   
     
     
         2 . The heat sink structure of  claim 1 , wherein the heat dissipation surface includes a plurality of radiation fins located thereon. 
     
     
         3 . The heat sink structure of  claim 2 , wherein the radiation fins are spaced from each other with a gap and positioned upright on the heat dissipation surface in a juxtaposed fashion. 
     
     
         4 . The heat sink structure of  claim 3 , wherein the radiation fins are caved to form at least one notch. 
     
     
         5 . The heat sink structure of  claim 1 , wherein the heat pipe is formed in a semicircular shape and includes a circular surface and a flat surface on two opposite sides, the circular surface facing downwards to contact with the groove and the flat surface facing upwards. 
     
     
         6 . The heat sink structure of  claim 1 , wherein the groove includes two sets formed in a crossed fashion, each of the grooves being formed in a curved shape. 
     
     
         7 . The heat sink structure of  claim 1 , wherein the groove includes three sets formed on the heat absorption surface in a juxtaposed fashion. 
     
     
         8 . The heat sink structure of  claim 7 , wherein two of the three sets of the grooves on outer sides are respectively formed in a curved fashion concaved outwards.
