Description of the invention: [Technical street field to which the invention belongs] The present invention relates to a method for manufacturing a heat dissipation plate, and more particularly to a heat dissipation plate manufacturing method which can save the cost of the metallurgical tool and at the same time effectively achieve the sintering of the uniformity of the copper powder. [Prior Art] According to the advancement of the technology era, the operating efficiency of electronic components is getting higher and higher, so that the functional requirements for the heat sink are also increased. The conventional heat sink has been widely used in order to increase the heat dissipation effect. The heat sink fin group is continuously developed and improved on the heat sink fins, so the high-efficiency heat sink is one of the most important research and development priorities in the industry today. Take the computer mainframe as an example, the heat generated by the internal central processing unit (cpu) is mostly, and in addition, the central processing unit will cause a decrease in performance when the heat is gradually increased, and when the heat accumulation is higher than its allowable limit, #Forcing the computer to crash is more likely to cause destruction of the image; and, in order to solve the problem of electromagnetic radiation, usually the chassis is used to close the computer host' so that the central processing unit and other heating components (or The rapid release of the thermal energy of the component is an important issue. In the heat conduction of heat-generating components such as processors, wafers, and lighting fixtures, the manufacturer uses the high heat transfer capacity of the heat sink, (4) heat transfer, high thermal conductivity, and no power consumption for large-area contact. Features, but suitable for heat conduction and heat dissipation requirements of heating elements. At present, the main structure of the heat-dissipating plate is _ piece mutually joined, 3 201016343 = ί is provided with copper powder, and its two copper _ is placed in a plurality of gift pieces, and the coffee piece « is tightly bonded to the closed one, and its layout The copper powder is evenly wound around the side of the spacer, which is complicated by the manufacturing process. Referring to Figure 1, the manufacturing method of the conventional heat sink is as follows: 'Step S11' combines the center mold with the copper sheet; Step S12' fills the center mold oil sheet with metal powder; Step S13 'Vibrating the copper piece and the center mold; Step S14', the center mold filled with the metal powder is sintered simultaneously with the copper piece; in step S15, the center mold is removed after sintering. In the prior art, a metal mold or a metal under cover sheet is used, and a central mold is combined with a copper sheet, and a metal powder is filled between the center mold and the copper sheet, and then the copper sheet and the center mold are vibrated to make the metal powder. The distribution is uniform, and the above-mentioned uniform sentence is filled into the center mold of the metal powder. The metal cover is placed in a sintering furnace for high-temperature sintering, and after the temperature is sintered, the metal powder forms a layer of capillary structure covering the copper sheet. The inner surface of the inner layer is then removed from the copper sheet. When the sintering furnace is sintered, a plurality of copper sheets are simultaneously sintered in the sintering furnace, and a central mold is disposed on each of the copper sheets, so that it is required to be used. Simultaneous sintering of a plurality of central molds results in the cost of requiring a large amount of filling fixtures, and the metal powder on the copper sheet must have more 201016343 & grooves in the metal powder after sintering. The central mold cannot be removed from the steel sheet before the copper sheet is sintered before the sintering is completed by the extension column of the towel mold. Avoid causing movement of the copper metal powder to move the last one groove recess and the destruction of the space, so the more necessary with a single central molding with a single sintered copper. Therefore, the prior art has the following disadvantages: 1. The cost of filling the tooling; 2. The construction is inconvenient; • 3. The cost is high.疋 ’ How to solve the above problems and lack of use, that is, the inventor of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

A plurality of grooves 31 are formed at the position of the spacer 121, and then the metal powder 3 of the heat sink 2 is sprayed with an organic liquid 4 such as alcohol or acetone so that the metal powder 3 can be shaped on the heat sink 2. At the same time, the shape of the groove 31 can be maintained, and the heat sink 2 can be taken out from the lower die 11 and the two heat sinks 2 can be assembled and moved to a graphite disk (not shown) for sintering to complete. The purpose of the heat dissipation plate is to achieve the effect of saving the cost of the tool and the convenience of construction, and also effectively preventing the displacement of the metal powder 3 caused by the movement of the heat sink 2, and when the two heat sinks 2 are assembled, The support member 32 can be assembled at the position of the groove 31 of the metal powder 3. The 201032343 cow 32 series of the two fins 2 can produce complete flatness when sintered. In addition, the above-mentioned scattered prescription _ can be changed according to the requirement, and the manufacturing method is as follows: Step S31' removes the squeezing device u under the left and right displacement of the squeegee u through the sliding mechanism 13; Step S32 scatters the heat sink 2 The powder filling device 1 is removed from the metallurgical tool 11; step S33 'the working tool 12 on the powder filling device 1 and the lower metallurgy tool u are closely engaged with each other' and the upper metallurgical tool 12 and the lower metallurgy tool are displaced via the sliding mechanism 13 At the position of the backfilling device 1; step S34' is filled with the metal powder 3 on the heat sink 2 in a positive pressure manner while vibrating the heat dissipation 2' so that the metal powder 3 is hooked on the diffuser 2; ',, step S35 , the upper smelting tool 12 and the lower smelting tool u are moved out through the sliding mechanism U' and the upper smelting tool 12 is opened and the metal powder 3 of the heat sink 2 is sprayed with the organic liquid 4; the step S36' takes the heat sink 2 from the lower smelting tool The crucible is taken out and the fins 2 are sintered.
