Heat sink for chips

Abstract

A heat sink includes a first heat dispensing unit including multiple heat dispensing plates between which chips are clamped. A base board is connected on a top of the first heat dispensing unit and a second heat dispensing unit is fixed on a top of the base board. The base board is connected to the first heat dispensing unit by two clamping members. The clamping members each have a first portion fixed to the base board and a second board which is removably connected to the first portion. The second portion is connected to the first heat dispensing unit. The second heat dispensing unit can be a fan, a water-cooling unit or an aluminum extruding member.

1 . A heat sink comprising:
 a first heat dispensing unit including multiple heat dispensing plates which are adapted to clamp chips therebetween;   a base board having a contact surface defined in an underside of the base board, the contact surface being shaped to directly match with a top of the first heat dispensing unit, a second heat dispensing unit fixed on a top of the base board, and   two clamping members connected to two ends of the base board and each of the clamping members including a first portion and a second portion which is removably connected to the first portion, the first portion having two extensions extending therefrom and the second portion including a handle and a frame which is connected to the handle, the extensions of the first portion removably connected to the second portion, the two respective frames connected to two ends of the first heat dispensing unit.   
   
   
       2 . The heat sink as claimed in  claim 1 , wherein each heat dispensing plate of the first heat dispensing unit includes protrusions on two ends thereof, the respective frames of the clamping members are hooked to the protrusions. 
   
   
       3 . The heat sink as claimed in  claim 1 , wherein the base board includes a hole defined therethrough and the second heat dispensing unit is located corresponding to the hole. 
   
   
       4 . The heat sink as claimed in  claim 1 , wherein the first portion of each of the clamping members includes a plate which is fixed on the base hoard and the two extensions extend from the plate, two L-shaped insertions extend from the two extensions respectively and each insertion includes a hook part, the handle of each of the clamping members is connected to the frame by a neck portion through which a slot is defined, the two insertions are inserted through the slot and the hook parts are engaged with a rear side of the neck portion. 
   
   
       5 . The heat sink as claimed in  claim 1 , the second heat dispensing unit is a fan. 
   
   
       6 . The heat sink as claimed in  claim 1 , the second heat dispensing units is a water-cooling unit. 
   
   
       7 . The heat sink as claimed in  claim 1 , the second heat dispensing unit is an aluminum extruding member. 
   
   
       8 . The heat sink as claimed in  claim 7 , wherein the aluminum extruding member includes multiple fins formed thereto.
