The spacers are tightly joined to the copper on both sides, and the layout of the::::=clear side is completed, and A凊 refers to the first figure, which is a manufacturing method of the conventional heat sink. The steps are as follows: /, step S11, combining the center mold with the copper sheet; step S12' filling the metal powder between the center mold and the copper sheet; step S13, vibrating the copper sheet and the center mold; step S14, filling the metal powder with the powder The center mold is sintered simultaneously with the copper sheet; in step S15, the center mold is removed after sintering. In the conventional technology, the copper piece of the metal cover or the lower cover can be combined with the central mold and the copper piece, and the metal mold is filled between the center mold and the copper piece, and then the copper piece and the center mold are vibrated. The metal powder is divided into materials, and the metal mold is filled with the metal mold, and the metal upper cover is simultaneously placed in a sintering furnace for high-temperature sintering. After high-temperature sintering, the metal powder forms a capillary structure covering the copper. The inner surface of the sheet is then removed from the copper sheet; wherein 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. It is necessary to use a plurality of central molds for sintering at the same time, thereby causing a large cost of filling the jig, and after the metal powder on the copper sheet is sintered, the metal powder must have a plurality of grooves and the formation of the grooves thereof It needs to be separated by the extension column of the center mold. Therefore, before the copper sheet is sintered, the center mold cannot be removed from the steel sheet to avoid it. Caused by the movement of the copper metal powder to move the last one groove recess and the destruction of the space, so the mono - Center more necessary with a single mold copper sintered. 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. Therefore, how to solve the above problems and lack of use, that is, the inventor of this case and the direction of the research and improvement of the secrets of the industry.
