Abstract

A heat sink includes a main body, a base formed on a bottom of the main body, and a conducting member attached to a bottom of the base. The heat exchange coefficient of the conducting member is higher than the heat exchange coefficient of the base.

Claims

exact text as granted — not AI-modified
1 . A heat sink, comprising:
 a base; and   a main body extending up from the base; and   a conducting member attached to a bottom of the base opposite to the main body;   wherein the heat exchange coefficient of the conducting member is larger than the heat exchange coefficient of the base.   
     
     
         2 . The heat sink of  claim 1 , wherein the main body is made of copper. 
     
     
         3 . The heat sink of  claim 1 , wherein the main body is made of aluminum. 
     
     
         4 . The heat sink of  claim 1 , wherein the conducting member is made of copper. 
     
     
         5 . The heat sink of  claim 1 , wherein the conducting member is made of graphite. 
     
     
         6 . The heat sink of  claim 1 , wherein a protrusion extends down from the bottom of the base, and the conducting member defines an opening, the protrusion extends through the opening of the conducting member.
