Thermal module and method of manufacturing same

Abstract

A thermal module includes a base and at least one heat pipe. The base has at least one groove formed on one face thereof and a recess formed on another opposite face thereof, and the recess is communicable with the at least one groove. The at least one heat pipe is correspondingly fitted in the at least one groove with one surface of the heat pipe flushing with a bottom of the groove to direct contact with a heat source, so as to avoid thermal resistance and more securely locate the heat pipe in the groove, allowing the thermal module to provide largely increased heat dissipation performance. A method of manufacturing the above thermal module is also disclosed.

1 . A thermal module, comprising:
 a base having a first face and an opposite second face; the first face being provided with at least one groove, and the second face being provided with a recess; and the at least one groove being communicable with the recess; and   at least one heat pipe being correspondingly fitted in the at least one groove.   
     
     
         2 . The thermal module as claimed in  claim 1 , wherein the groove each has an open side and a closed side; and the open side has a width smaller than that of the closed side. 
     
     
         3 . The thermal module as claimed in  claim 1 , further comprising a plate being correspondingly covered onto the at least one groove formed on the first face of the base. 
     
     
         4 . The thermal module as claimed in  claim 3 , wherein the plate is provided at each of four corners with at least one mounting hole. 
     
     
         5 . The thermal module as claimed in  claim 3 , further comprising at least one coupling unit; the coupling unit each including a female connector arranged on the first face of the base and a male connector correspondingly arranged on one 
     
     
         6 . The thermal module as claimed in  claim 3 , further comprising at least one coupling unit; the coupling unit each including a female connector arranged on one side of the plate facing toward the first face of the base and a male connector correspondingly arranged the first face of the base, such that the female and the male connector are correspondingly engaged with each other. 
     
     
         7 . The thermal module as claimed in  claim 1 , wherein the heat pipe each includes a first surface and an opposite second surface that are directly connected at respective two lateral edges with one another. 
     
     
         8 . The thermal module as claimed in  claim 1 , wherein the base further includes a first, a second, a third and a fourth extended section, on each of which at least one mounting hole is provided. 
     
     
         9 . A method of manufacturing thermal module, comprising the following steps:
 providing at least one heat pipe and a base having at least one groove formed one face thereof and a recess formed on an opposite face thereof; and   correspondingly fitting the at least heat pipe in the at least one groove on the base.   
     
     
         10 . The method of manufacturing a thermal module as claimed in  claim 9 , further comprising the following steps: providing a plate; and correspondingly covering the plate onto the at least one groove to confine the at least heat pipe in the groove.
