Heat sink assembly

Abstract

A heat sink assembly includes a fan and two sets of fin modules. The fan generates airflow along a first direction. The two sets of fin modules are fixed on opposite sides of the fan. Each set of fin module has a plurality of parallel fins. The fins extend parallel to the first direction.

1 . A heat sink assembly comprising:
 a fan generating airflow along a first direction;   two sets of fin modules fixed on opposite sides of the fan, each set of fin module having a plurality of parallel fins, wherein the fins extend parallel to the first direction.   
     
     
         2 . The heat sink assembly of  claim 1 , wherein an exposed surface of each set of fin module is approximately equal to an area of the face of the fan. 
     
     
         3 . The heat sink assembly of  claim 1 , wherein a through hole is defined in each fin module to accommodate a fastener. 
     
     
         4 . The heat sink assembly of  claim 1 , wherein at least one heat pipe is located in each fin module. 
     
     
         5 . The heat sink assembly of  claim 1 , wherein a bracket is located on a bottom portion of the fin modules to support the fin modules. 
     
     
         6 . The heat sink assembly of  claim 5 , wherein each fin is parallel to a top portion of the bracket. 
     
     
         7 . A heat dissipater comprising:
 two fin modules, each fin module having a plurality of parallel fins;   a fan sandwiched between the two fin modules, the fan having an inlet toward one fin module and an outlet toward the other fin module, each fin is perpendicular to a face of the fan.   
     
     
         8 . The heat dissipater of  claim 7 , wherein an exposed surface of each fin module is approximately equal to an area of the face of the fan. 
     
     
         9 . The heat dissipater of  claim 7 , wherein each fin is rectangle-shaped. 
     
     
         10 . The heat dissipater of  claim 7 , wherein a hole is defined in each fin module to accommodate a fastener. 
     
     
         11 . The heat dissipater of  claim 10 , wherein a diameter of the hole is larger than a diameter of the fastener. 
     
     
         12 . The heat dissipater of  claim 7 , wherein the fin modules further comprise of heat pipes. 
     
     
         13 . The heat dissipater of  claim 7 , wherein a bracket is located on a bottom portion of the fin modules to support the fin modules. 
     
     
         14 . The heat dissipater of  claim 7 , wherein each fin is parallel to a top portion of the bracket.
