FIELD OF THE INVENTION [0001] The present invention relates to a dissipation heat pipe structure and corresponding manufacturing method and, more particularly, to the manufacturing method for manufacturing a heat conduction material combining a metal with a bracket structure of carbon element. BACKGROUND OF THE INVENTION [0002] In recent years, the pace of high technology industry development is extremely fast, the development of electronic components is toward small volumes and high densities. The efficiency requirements for the aforesaid components also increase that generates much waste heat. The efficiency of the electronic components will be decreased and destroyed if the waste heat is unable to eliminate appropriately. Therefore, various heat conduction materials are provided to improve the efficiency of heat dissipation. [0003] In the prior art, the material applying in the heat dissipation structure usually includes copper or aluminum to be the tendency of current heat dissipation technology. Traditionally, aluminum applying in the heat dissipation material is restricted to cause a bottleneck because of high temperature conduction is produced by the efficiency upgrade of central processors. Copper applying in the heat dissipation technology is then provided. However, copper has a higher specific gravity that has disadvantage to shape and the application is restricted. Although both copper and aluminum are used for air cooling to implement heat dissipation, the air cooling incorporating the aforesaid copper and aluminum will be unable to satisfy the demand for heat dissipating when the heat release of chips achieves 50 W/cm.sup.2. Therefore, the high efficiency of heat dissipation materials needs to improve. [0004] In addition, to satisfy the demand for the heat dissipation and the space restriction, a dissipation heat pipe is in widespread use for conducting heat. The dissipation heat pipe can be used in a small and narrow space by using a fluid within the dissipation heat pipe to absorb and release heat to generate a phase change for conducting heat. A greater heat transfer can be generated by the dissipation heat pipe at a slight temperature difference and there is a reputation of "heat superconductor" for the dissipation heat pipe. Therefore, a conventional heat dissipation module is developed and comprises at least one dissipation heat pipe, at least one heat dissipation slip, and a plurality of heat sink fins. [0005] Referring to FIG. 1, a schematic diagram illustrates a conventional heat dissipation module and a heat conduction process. The heat dissipation module as shown in FIG. 1 comprises a heat dissipation slip 11, a dissipation heat pipe 12 and a plurality of heat sink fins 13. The heat dissipation slip 11 includes a lower surface 111 and an upper surface 112 which is corresponded to the lower surface 111. The heat conduction process is that the lower surface 111 of the heat dissipation slip 11 is contacted to a waste heat generated by a heat source first of all. The waste heat is then conducted to the upper surface 112 of the heat dissipation slip 11. The dissipation heat pipe 12 comprises a heat source end 121 and a heat dissipation end 122. The heat source end 121 is coupled to the upper surface 112 of the heat dissipation slip 11. The waste heat is conducted to the heat dissipation end 122 of the dissipation heat pipe 12 from the heat source end 121 of the dissipation heat pipe 12. A bottom 131 is formed by the plurality of heat sink fins 13. Specifically the bottom 131 is composed of each edge of each fin. The heat dissipation end 122 of the dissipation heat pipe 12 is contacted to the bottom 131 to conduct the waste heat to the plurality of heat sink fins 13. Lastly, the waste heat is discharged through the convection and the radiating. [0006] Besides, diamonds are well known and have characteristics with the highest hardness, the fastest heat conduction, and the widest refraction range in current materials. Diamonds, therefore, are always one of more important materials in engineering due to the excellent characteristics. The thermal conductivity of diamonds at the normal atmospheric temperature is five times more than copper. Moreover, the thermal expansion factor of diamonds at high temperature is very small that shows the excellent efficiency for heat dissipating. The feature may help people to differentiate the adulteration of diamonds. In the prior art, many technologies and manufacture procedures have been developed to make diamonds. The direct decomposition for hydrocarbons is the most familiar method like Microwave Plasma Enhance Chemical Vapor Deposition (MPCVD) and Hot Filament CVD (HFCVD). By the aforesaid methods, polycrystalline diamond films can be deposited. The characteristic of the polycrystalline diamond films is same as the single crystal diamonds. SUMMARY OF THE INVENTION [0007] Briefly, to eliminate the waste heat generated by electronic components efficiently and to face the development tendency of electronic components with small volumes and high densities, the object of the present invention is to provide a heat conduction material which is applied for a dissipation heat pipe to improve the efficiency of heat dissipation for a chip. The waste heat caused by the high temperature, which is generated from the operation of the chip, can be reduced. In addition, the heat conduction material provided by the present invention is not only restricted for the heat dissipation of the chip, but is also applied for other heat conduction apparatuses. [0008] The heat conduction material provided by the present invention is applied for a dissipation heat pipe and the heat conduction material comprises combining a metal with a bracket structure of carbon element. The metal can be copper or aluminum or other metals with high thermal conductivity. The bracket structure of carbon element is diamonds and can also be used for coating on the metal surface or for encapsulating in materials. The bracket structure of carbon element can be further used in combining the metal with the materials. [0009] The heat conduction material can be made by chemical vapor deposition, physical vapor deposition, melting, electroplating or other manufacturing methods. Other features and advantages of the present invention and variations thereof will become apparent from the following description, drawings, and claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0017] Referring to FIG. 2, a schematic diagram illustrates a die for manufacturing a dissipation heat pipe which has an end without sealing according to an embodiment of the present invention. The die comprises a mold material supplier 21, a mold material injector 22 and a mold 23. A mold material is injected by the mold material injector 22 to a cavity 24 of the mold 23 for molding. The shape is a hollow closed pipe which has an end without sealing. The mold material can be a metal material or a melt material which combines a metal with a bracket structure of carbon element. The metal is copper or aluminum or silver or other metals with high thermal conductivity or other material combinations. The melting point of the bracket structure of carbon element is higher than any metal of the mentioned above. Therefore, the bracket structure of carbon element can be mixed with those metals to form a mold material. [0018] The hollow closed pipe of a dissipation heat pipe 31 has an end without sealing according to FIG. 2. A wick structure 314 is formed around an interior wall 313 of the hollow closed pipe as shown in FIG. 3. The wick structure 314 which possesses groove shapes is etched by microstructure manufacturing from the interior wall 313. As shown in FIG. 4, the wick structure 314 of the interior wall 313 can also be made by sintering via a metal mesh around the interior wall 313. [0019] Lastly, referring to FIG. 5, a perspective drawing illustrates the dissipation heat pipe 31 which has the end with sealing after filling a type of fluid 14 according to FIG. 3 or FIG. 4. The heat conduction process for the dissipation heat pipe 31 is that a heat source end 311 of the dissipation heat pipe 31 is connected to the upper surface 112 of the heat dissipation slip 11 as shown in FIG. 1. The waste heat which is distributed on the upper surface 112 is conducted to the liquid fluid 14 within the hollow closed pipe from the heat source end 311. The waste heat is then absorbed by the liquid fluid 14 to implement a phase change for vaporizing the liquid fluid 14 to be the gaseous fluid 14. The waste heat carried by the gaseous fluid 14 is conducted onto the bottom 131 of the plurality of heat sink fins 13 as shown in FIG. 1 through the heat dissipation end 312 when the gaseous fluid 14 is diffused to a heat dissipation end 312 of the dissipation heat pipe 31 and is then contacted to the interior wall 313 of the heat dissipation end 312. The gaseous fluid 14 is implemented via the phase change again and is then condensed to the liquid fluid 14. The liquid fluid 14 further returns to the heat source end 311 through the forcing of the wick structure 314 of the interior wall 313. The aforesaid circulation process may help to discharge much heat. The heat is absorbed or released by the dissipation heat pipe 31 via the vaporization and the condensation of the type of liquid. Therefore, the dissipation heat pipe 31 possesses the outstanding heat conduction efficiency. The type of fluid 14 within the dissipation heat pipe 31 can be composed of water or liquids having heat conduction capacity.
