Heat sink equipped with a vapor chamber

Abstract

A heat sink equipped with a vapor chamber includes a heat conduction plate and a vapor chamber. The heat conduction plate has one side formed integrally a plurality of radiation fins and another side with two lateral edges formed respectively and integrally a fastening portion. The two fastening portions are interposed by a recess to bond the vapor chamber. Each fastening portion is fastened to a printed circuit board through at least one screw to allow the vapor chamber to contact a heat generation element. The fastening portion is integrally formed at a desired thickness, thus has sufficient strength to withstand the fastening force of the screw to prevent tight sealing between the vapor chamber and heat generation element affected by deformation of the heat conduction plate. Thereby the vapor chamber can smoothly contact the heat generation element to rapidly transfer heat outside.

1 . A heat sink equipped with a vapor chamber, comprising:
 a heat conduction plate which includes one side formed integrally a plurality of radiation fins and another side with two lateral edges formed respectively and integrally a fastening portion, the two fastening portions being interposed by a recess; and   a vapor chamber being bonded to the recess.   
     
     
         2 . The heat sink of  claim 1 , wherein the heat conduction plate includes a latch flange respectively on a front side and a rear side of the recess and an airtight compartment dug downwards, such that the vapor chamber is positioned and surrounded by the two latch flanges and the two fastening portions to cover and seal the airtight compartment. 
     
     
         3 . The heat sink of  claim 2 , wherein the vapor chamber includes a plurality of heat conduction fins extended into the airtight compartment. 
     
     
         4 . The heat sink of  claim 2 , wherein the heat conduction plate includes an air extraction vent communicating with the airtight compartment. 
     
     
         5 . The heat sink of  claim 1 , wherein each fastening portion includes at least one aperture run through by at least one screw. 
     
     
         6 . The heat sink of  claim 5 , wherein the screw is coupled with a spring.
