Thermal module

Abstract

A thermal module includes at least one heat pipe and a heat sink. The heat pipe has a heat absorption end and a heat-spreading end extending in a direction away from the heat absorption end. The heat sink has a heat-spreading face on which multiple radiating fins are disposed and a heat conduction face opposite to the heat-spreading face. The heat conduction face is formed with a reception channel. The heat-spreading end of the heat pipe is press-fitted in the reception channel to integrally connect the heat pipe and the heat sink with each other. The heat-spreading end is flush with the heat conduction face. The heat pipe and the heat sink are connected by means of press fit connection. Therefore, the thermal module can be easily assembled to save working time and lower manufacturing cost. Moreover, the thermal module is able to provide excellent heat dissipation effect.

1 . A thermal module comprising:
 at least one heat pipe having a heat absorption end and a heat-spreading end extending in a direction away from the heat absorption end; and   a heat sink having a heat-spreading face and a heat conduction face opposite to the heat-spreading face, multiple radiating fins being disposed on the heat-spreading face, the heat conduction face being recessed to form a reception channel, whereby the heat-spreading end of the heat pipe is press-fitted in the reception channel of the heat sink to integrally connect the heat pipe and the heat sink with each other, the heat-spreading end being flush with the heat conduction face.   
     
     
         2 . The thermal module as claimed in  claim 1 , wherein the heat sink has a heat-spreading base, the heat-spreading face being formed on a first face of the heat-spreading base, the heat conduction face being formed on a second face of the heat-spreading base. 
     
     
         3 . The thermal module as claimed in  claim 1 , further comprising a heat conduction base, the heat conduction base having a groove formed on a third face of the heat conduction base, whereby the heat absorption end of the heat pipe is press-fitted in the groove to integrally connect with the heat conduction base, a fourth face of the heat conduction base attaching to a heat-generating component. 
     
     
         4 . The thermal module as claimed in  claim 1 , wherein the reception channel has a closed side and an open side opposite to the closed side, the closed side and the open side together defining the reception channel. 
     
     
         5 . The thermal module as claimed in  claim 4 , wherein the heat-spreading end has a plane face and a non-planar face axially extending along the plane face, the plane face being flush with the open side and the heat conduction face, the non-planar face being tightly and snugly attached to the closed side of the reception channel.
