Heat-dissipation structure and manufacturing method thereof

Abstract

A heat-dissipation structure and a manufacturing method thereof are disclosed. The heat-dissipation structure includes a base having a main body and a tube. The tube has an inlet, an outlet, and a tube body; and the tube body is correspondingly embedded in the main body to serve as a flow passage while the inlet and the outlet are exposed from the main body. The heat-dissipation structure can be manufactured by pour molding or insert molding to embed the tube in the base for serving as a flow passage. With the manufacturing method, the heat-dissipation structure can be formed at reduced material, labor and time costs without the risk of water leakage.

1 . A heat-dissipation structure, comprising:
 a base including a main body and at least one tube; the tube having an inlet, an outlet, and a tube body; the tube body being correspondingly embedded in the main body while the inlet and the outlet of the tube being exposed from the main body.   
     
     
         2 . The heat-dissipation structure as claimed in  claim 1 , wherein the main body includes a first part and a second part; the first and the second part being in contact with and connected to each other; and the tube body of the tube being correspondingly sandwiched between the first and the second part. 
     
     
         3 . The heat-dissipation structure as claimed in  claim 1 , wherein the base and the tube are made of a material selected from the group consisting of a copper material, an aluminum material, and a stainless steel material. 
     
     
         4 . The heat-dissipation structure as claimed in  claim 2 , wherein the second part of the main body is made of a material selected from the group consisting of a non-metal material and a material with relatively good heat-dissipation efficiency; and wherein the non-metal material is a plastic material, and the material with relatively good heat-dissipation efficiency is an aluminum material. 
     
     
         5 . The heat-dissipation structure as claimed in  claim 2 , wherein the first part and the second part of the main body as well as the tube are formed into an integral body by insert molding. 
     
     
         6 . The heat-dissipation structure as claimed in  claim 2 , wherein the first part further includes at least one first groove, and the second part further includes at least one second groove corresponding to the first groove; such that the first and the second groove can be correspondingly closed to one another to enclose the tube body of the tube therein. 
     
     
         7 . A method of manufacturing heat-dissipation structure, comprising the following steps:
 providing a mold having a mold cavity and a tube; and   positioning the tube in the mold cavity of the mold, and forming a main body in the mold by pour molding to embed the tube in the main body.   
     
     
         8 . The manufacturing method as claimed in  claim 7 , wherein the main body is formed in a manner selected from the group consisting of injection molding and casting. 
     
     
         9 . A method of manufacturing heat-dissipation structure, comprising the following steps:
 providing a mold having a mold cavity, a first body, and a tube; and   positioning the tube on a top of the first body; placing the first body having the tube positioned thereon in the mold cavity of the mold; and forming a second body on the top of the first body to cover the first body and the tube, so that the second body, the first body, and the tube form an integral body.   
     
     
         10 . The manufacturing method as claimed in  claim 9 , wherein the second body is formed on the top of the first body in a manner selected from the group consisting of injection molding and casting. 
     
     
         11 . A method of manufacturing heat-dissipation structure, comprising the following steps:
 providing a mold having a mold cavity, a first body having a groove provided on a top thereof, and a tube; and   setting the tube in the groove provided on the top of the first body, placing the first body having the tube set in the groove in the mold cavity of the mold, and forming a second body on the top of the first body to cover the first body and the tube, so that the second body, the first body and the tube form an integral body.   
     
     
         12 . The manufacturing method as claimed in  claim 11 , wherein the second body is formed on the top of the first body in a manner selected from the group consisting of injection molding and casting.
