Heat-conducting module and method for manufacturing the same

Abstract

The present invention relates to a heat-conducting module and a method for manufacturing the same. A hollow aluminum tube ( 110 ) is put on a corresponding heat pipe ( 111 ) to form an aluminum-skinned heat pipe ( 11 ). Then, one or more aluminum-skinned heat pipes ( 11 ) are disposed in a casting space ( 22 ) of a die casting mold ( 2 ). Molten aluminum materials are filled in the die casting space ( 11 ) of the die casting mold ( 2 ) to form a heat-conducting module ( 1 ). By using a die casting process, molten aluminum materials are used to cover at least one aluminum-skinned heat pipe ( 11 ), thereby finishing the heat-conducting module ( 1 ).

What is claimed is: 
     
         1 . A method for manufacturing a heat-conducting module, including steps of:
 a) putting a hollow aluminum tube ( 110 ) on a corresponding heat pipe ( 111 ) to form an aluminum-skinned heat pipe ( 11 );   b) disposing the at least one aluminum-skinned heat pipe ( 11 ) into a casting space ( 22 ) of a die casting mold ( 2 ); and   c) filling aluminum materials into the casting space ( 22 ) of the die casting mold ( 2 ) to form a heat-conducting module ( 1 ), wherein the heat-conducting module ( 1 ) comprises an aluminum base ( 10 ) and the at least one aluminum-skinned heat pipe ( 11 ), and the aluminum base ( 10 ) covers the at least one aluminum-skinned heat pipe ( 11 );   wherein molten aluminum materials cover the at least one aluminum-skinned heat pipe ( 11 ) by a die casting process to thereby form the heat-conducting module ( 1 ).   
     
     
         2 . The method according to  claim 1 , wherein the aluminum-skinned heat pipe ( 11 ) in the step a) is made by drawing the hollow aluminum tube ( 110 ) to cover the heat pipe ( 111 ). 
     
     
         3 . The method according to  claim 2 , further including a step of sealing both ends of the hollow aluminum tube ( 110 ) with two aluminum sealing heads ( 112 ). 
     
     
         4 . The method according to  claim 1 , wherein the die casting mold ( 2 ) in the step b) comprises a first mold part ( 20 ) and a second mold part ( 21 ), and the first mold part ( 20 ) and the second mold part ( 21 ) are brought into tight contact with each other to form the casting space ( 22 ), thereby forming the aluminum base ( 10 ). 
     
     
         5 . A heat-conducting module, including:
 an aluminum base ( 10 ); and   at least one aluminum-skinned heat pipe ( 11 ) disposed in the aluminum base ( 10 );   wherein the aluminum-skinned heat pipe ( 11 ) comprises a heat pipe ( 111 ) and an aluminum tube ( 110 ) covering the heat pipe ( 111 ).   
     
     
         6 . The heat-conducting module according to  claim 5 , wherein the aluminum base ( 10 ) is made of aluminum-based metals or alloys thereof. 
     
     
         7 . The heat-conducting module according to  claim 5 , wherein a plurality of aluminum-skinned heat pipes ( 11 ) are disposed in the aluminum base ( 10 ) at intervals. 
     
     
         8 . The heat-conducting module according to  claim 5 , wherein the aluminum-skinned heat pipe ( 11 ) is sealed by aluminum sealing heads ( 112 ) at both ends ( 113 ) of the aluminum tube ( 110 ). 
     
     
         9 . The heat-conducting module according to  claim 8 , wherein the aluminum sealing heads ( 112 ) are made of aluminum-based metals or alloys. 
     
     
         10 . The heat-conducting module according to  claim 5 , wherein the aluminum tube ( 110 ) is made of aluminum-based metals or alloys. 
     
     
         11 . The heat-conducting module according to  claim 5 , wherein the aluminum pipe ( 110 ) is a hollow tube to be put on the heat pipe ( 111 ).
