The manufacturing method of the high-density heat sink of the present invention is divided into two steps. The first step is to provide a mold 30 having a specific shape. The front and back surfaces of the mold 30 have the same cross-sectional shape, and an arc-shaped hole 3 3 is formed on the front surface and a plurality of arc-shaped holes are passed through from the rear. 3 3 Square holes 3 1 extending radially upward, and the bottom end of the mold between two adjacent square holes 3 1 respectively protrudes downward by a convex portion 3 5 'Squeeze a block heated to an appropriate temperature into the mold and determine An intermediate 10 was obtained after long cutting. The intermediate body includes an arc-shaped base 12, a plurality of heat sinking fins 14 extending radially upward from the base 12 and a groove 16 between the heat-dissipating fins 14. The upper part and the lower part of the heat dissipation fin n have the same width, and a "V" -shaped notch 18 communicating with the groove 16 is formed on the top surface of the base 12. The density heat dissipation method of the present invention is a manufacturing method The second step is: flatten the arc-shaped base 12 of the middle door body 10 to obtain a heat sink 20, and at this time, the plurality of fins 14 are arranged parallel to each other, and the widths of the grooves 16 are the same from top to bottom. , ... The grooves 18 are densely stitched. In order to enhance the bottom surface of the loose seat 12 to be extruded to the end, the die 30 is extended to form a mold, so that the distance between the base 20 and the base 20 The whole degree is calculated by the top of the slot 16. The slot 16 is used when the heater 20 is of the pole-polishing type. Therefore, it is used in the middle of the heat source. The invention is separated from the heat source mold 30 and the body 1 is avoided. More recent
