The manufacturing process is such that the present invention is based on the heat dissipation according to the present invention. Referring to the manufacturing flow chart of the sheets shown in Figs. 4 to 6 . First, as shown in FIG. 4, a plate 4 is first fed into a machine tool (not shown), wherein the machine tool can be implemented as a two-punch machine and can be used when the plate 40 is fed. The sheet 4 is stamped and formed by a corresponding mold of the type of the fins 3 as shown in Fig. 3. In particular, it is noted that the pole material 4 is formed by a plurality of notches 41 when the stamping is taken at an appropriate distance, wherein the appropriate distance here may be equal or unequal length, According to the production cost requirement, for example, when the appropriate distance is taken, the notches 41 may be formed at intervals of seven centimeters, or the gaps may be formed in the order of seven centimeters, five centimeters apart, and seven centimeters apart. The notch 41 can be V-shaped, semi-elliptical, concave-shaped, U-shaped, semi-circular or trapezoidal, etc., wherein the notches 41 are V-shaped, and any two longitudinally oppositely disposed notches 41 are in abutment One of the imaginary cutting lines 42 is formed, and any one of the two transverse lines 200847909 is formed with a imaginary one-fold line 37 向 between the valleys of the oppositely disposed notches 41. Referring to FIG. 5, the plate has been stamped. 4〇, the folding line 37 can be used to fold the folded portion 3丨 relative to the sheet 30 by 90 degrees, and the first joint portion 32 is extended in a direction different from the direction in which the portion 31 is turned. And out, and then by the cutting tool along the cutting line 42 After cutting, it is made of the first as shown in FIG. 6 may be the heat sink 3. Referring to FIG. 7, when a plurality of heat sinks 3 as shown in FIG. 6 are stacked together, each of the heat sinks 3 can be coupled to the other heat sink 3 by the first joint portion 32 thereof. The second bonding portion 34 is combined, wherein the bonding manner is combined, for example, but not limited to, by laser welding, dispensing or bonding. It is worth noting here that the spacing between each of the heat sinks 3 is controlled by the distance D2 between the first reference edge 35 and the second reference edge %, wherein the spacing between the heat sinks 3 can be Because the producer changes for specific production needs, for example, the distance 〇2 plus or minus one millimeter (±lmm) is the control range of the distance, and the distance D2 is set at the time of mold design, so the stamping is performed. In the rear heat sink 3, the distance (10) between the two reference sides 35, 36 is also fixed, and the dimensional accuracy is not affected; furthermore, the use of the positioning pin can be omitted by the above method, thereby The plate 4 does not have to reserve an area in which the positioning pin is inserted, and in the process of the manufacturing method of the present invention, there is no waste generated, which is quite economical. Finally, please refer to FIG. 8 , which is a plan view of a heat sink of another preferred embodiment of the present invention. In the embodiment, the heat sink 5 has a body 5〇, a folded portion 5, a first joint portion 52 and a notch 53, wherein the structure is substantially the same as the heat sink 3 shown in FIG. The main difference is that the design of the second joint portion 34 (see FIG. 3) is omitted on the folded portion 51 of the heat sink 5 in the embodiment; thus, the heat sink 5 is When the other heat sink 5 is to be combined, the portion of the first joint portion 52 of the secondary heat sink 5 will be superimposed on the folded portion 51 of the front heat sink 5 (such as the dotted line on the folded portion 51). Partially, and thus formed with a third reference edge 55, in which the spacing between the two heat sinks 5 is the first reference of the third reference edge 55 and the first coupling portion 52. The distance D3 between the edges 54 controls 'of course' here also because of the manufacturer's demand = the distance D3 plus or minus one millimeter (±lmm) is the control cost of the pitch. In addition, the method for manufacturing the heat sink 5 shown in this embodiment is the same as the method for manufacturing the heat sink 3 of the foregoing embodiment. The difference is only in the design of the mold type, so the manufacturing method is not otherwise Declare. In summary, the heat sink of the present invention and the manufacturing method thereof have an innovative design of the heat sink which predefines the distance between the plurality of heat sink combinations in the future, which omits the scrap which must be provided by the positioning pin, and also ensures the assembly. The precision of the finished product is very accurate, and the manufacturing method is very economical and the precise size that can be achieved makes the several heat sinks have a δ _ not easy to make mistakes, and can greatly reduce the unnecessary consumption during production.
