Heat dissipating apparatus

Abstract

A heat dissipating apparatus includes a heat-generating electronic component, a heat pipe, a heat sink. The heat sink includes a bottom panel, a top panel, and a plurality of fins. An air intake is defined between the bottom panel and the top panel. The plurality of fins defines a first air outlet and a second air outlet. An air guiding wall extends through the plurality of fins. The air intake, the air guiding wall, and the first air outlet together define a first air passage for air extending through the heat sink, and the air intake, the air guiding wall, and the second air outlet together define a second air passage for air extending through the heat sink. The invention further provides an assembly with the heat dissipating apparatus.

         2 . The heat dissipating apparatus of  claim 1 , wherein an air guiding piece perpendicularly extends from each of the plurality of fins, and the air guiding wall is defined by the air guiding piece of each of the plurality of fins. 
     
     
         3 . The heat dissipating apparatus of  claim 2 , wherein the air guiding piece is slanted relative to the bottom panel. 
     
     
         4 . The heat dissipating apparatus of  claim 2 , wherein each of the plurality of fins defines an opening, and the air guiding piece extends from an edge of the opening. 
     
     
         5 . The heat dissipating apparatus of  claim 2 , wherein a width of the air guiding piece is substantially equal to a distance between every two adjacent fins of the plurality of fins. 
     
     
         6 . The heat dissipating apparatus of  claim 1 , wherein a distal end of each of the plurality of fins is substantially arcuate. 
     
     
         7 . An assembly comprising:
 an electronic component;   a heat sink comprising a bottom panel, a top panel, and a plurality of fins located between the bottom panel and the top panel; an air intake defined between the bottom panel and the top panel; the plurality of fins defining a first air outlet and a second air outlet substantially perpendicular to the first air outlet; the first air outlet opposite to the air intake; an air guiding wall extending through the plurality of fins;   a heat pipe connected to the electronic component and the heat sink; and   a fan, attached to the heat sink, comprising a fan air intake and a fan air outlet;   wherein air outside of the fan flows into the fan via the fan air intake, through the fan air outlet and into the heat sink via the air intake, a first part of the air flows out of the heat sink via the first air outlet, and a second part of the air flows out of the heat sink via the second air outlet by the air guiding wall.   
     
     
         8 . The assembly of  claim 7 , wherein an air guiding piece perpendicularly extends from each of the plurality of fins, and the air guiding wall is defined by the air guiding piece of each of the plurality of fins. 
     
     
         9 . The assembly of  claim 8 , wherein the air guiding piece is slanted relative to the bottom panel. 
     
     
         10 . The assembly of  claim 8 , wherein each of the plurality of fins defines an opening, and the air guiding piece extends from an edge of the opening. 
     
     
         11 . The assembly of  claim 8 , wherein a width of the air guiding piece is substantially equal to a distance between every adjacent two of the plurality of fins. 
     
     
         12 . The assembly of  claim 7 , wherein a distal end of each of the plurality of fins is substantially arcuate.
