Thermal module

Abstract

A thermal module includes a heat sink and a heat pipe. The heat sink has a heat absorption section and a heat dissipation section. The heat dissipation section has multiple radiating fins. The heat absorption section is formed with at least one receiving groove. The heat pipe is received in the receiving groove. The heat pipe has a first end, a second end, a middle section and at least one conduction section. The first and second ends and the middle section are arranged in adjacency to each other to together define a first section. The conduction section winds around the first section.

What is claimed is: 
     
         1 . A thermal module comprising:
 a heat sink having a heat absorption section and a heat dissipation section, the heat dissipation section having multiple radiating fins, the heat absorption section being formed with at least one receiving groove; and   a heat pipe received in the receiving groove, the heat pipe having a first end, a second end, a middle section and at least one conduction section, the first and second ends and the middle section being arranged in adjacency to each other to together define a first section, the conduction section winding around the first section.   
     
     
         2 . The thermal module as claimed in  claim 1 , wherein the receiving groove has a heat absorption section and a spreading section, the heat absorption section being disposed on inner side of the spreading section, the first section of the heat pipe being disposed in the heat absorption section, while the conduction section of the heat pipe being disposed in the spreading section. 
     
     
         3 . The thermal module as claimed in  claim 1 , wherein the first section of the heat pipe is adjacent to the conduction section and as a whole, the heat pipe has an asymmetrical form. 
     
     
         4 . The thermal module as claimed in  claim 1 , wherein the receiving groove has an open side and a closed side, the heat pipe having a first side and a second side, the first side of the heat pipe being correspondingly attached to the closed side, the second side of the heat pipe being correspondingly positioned in the open side. 
     
     
         5 . The thermal module as claimed in  claim 4 , wherein one of the first and second sides of the heat pipe has a flat form. 
     
     
         6 . The thermal module as claimed in  claim 4 , wherein both the first and second sides of the heat pipe have a flat form. 
     
     
         7 . The thermal module as claimed in  claim 1 , further comprising a substrate attached to the first section of the heat pipe. 
     
     
         8 . The thermal module as claimed in  claim 1 , further comprising a substrate attached to the heat pipe.
