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).

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat-conducting module and a method for manufacturing the same. Particularly, the present invention relates to a heat-conducting module which is made by using molten metallic materials to cover aluminum-skinned heat pipes via a die casting process and a method for manufacturing the same.[0003]2. Description of Prior Art[0004]Heat-conducting elements such as heat pipes are used to dissipate heat or transfer heat. The interior of the heat pipe is made to be vacuumed. A working fluid is filled into the heat pipe to generate a phase change therein. When the working fluid is heated, it evaporates to become vapors, thereby carrying away the heat. Then, the vapor phase of the working fluid condenses to return its liquid phase and to circulate in the heat pipe. In order to manufacture a plate-type heat pipe, conventionally, a plurality of heat pipes is disposed in a solid or hollow metallic pl...

AI Technical Summary

Benefits of technology

The present invention provides a heat-conducting module that uses molten metallic materials to cover at least one aluminum-skinned heat pipe. This heat-conducting module is made through a die casting process, and aluminum material is used as the heat-conducting medium in view of its good heat-dissipating and heat transfer effects. Additionally, this heat-conducting module is chemically stable and has better corrosion resistance.

Problems solved by technology

However, the strength of the conventional plate-type heat pipe is insufficient.

Further, it is difficult for heat-dissipating elements such as fins to be provided on the conventional plate-type heat pipe.

As for the plate-type heat pipe formed by covering heat pipes by a solid or hollow metallic plate, it is an important issue to consider the thermal resistance generated by the gap between the heat pipe and the metallic plate.

As for the plate-type heat pipe made by heat pipes penetrating into a solid metallic plate, it is difficult to control the tolerance between the penetrating heat pipe and the metallic plate.

If the tolerance is smaller, the penetration of the heat pipe into the metallic plate becomes more difficult.

As for the plate-type heat pipe made by embedding heat pipes in a metallic plate, the heat transfer effect between the heat pipe and the metallic plate will be deteriorated because the metallic plate is made of a material (aluminum) different from the material (copper) of the heat pipe.
