Then, through the two fixtures Then, through (four) copies, the office is suspended. ~, the part of the aluminum piece is suspended, causing the aluminum piece to be clamped in the τ word diagram 322. 2, 'the other part of the name The lack of sheet formation = 0 = the base Γ guide 3 〇 2 through the Korean piece % 之 之 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 并且 并且 并且 并且 并且 并且 并且 并且 并且 并且The 2nd extension of 3°2 is not shown). As shown in Figure 5, the first B of the clip is parallel to the top plane 3024 of the guide 302. The dissipating portion 324 > extends in the extending direction E2, and the second extending direction E2 is perpendicular to the top plane 3024 of the mouth 4 and the first extending direction m. (4) 3〇2 As shown in Fig. 3, Fig. 4 and Fig. 5, due to the size of the cross section of one of the guide rails 3〇2 of the notch 32〇, the notch 32 of the piece 32 and the base 30, and the mouth 4' of the Korean piece 32〇 The guide 3〇2 with the base 3 does not matter 9 201007438 The contact is also tight, that is, the notch 32〇 and the guide rail 3〇2 are loosely matched and = worn, shaped, attached to the block 32 and the fifth, the notch 320 The width D3 is greater than the visibility D5' of the top 3〇2〇 of the rail 3〇2 and thus the rail 3〇2 can pass through the notch 32 of the fin 32 and the notch 320 is in close contact. ^,

Since there is not much contact between the fins #32 and the base 30, the friction does not occur when combined. Therefore, when the fins 32 are combined with the base Deng, the pieces 32 are assembled on the base without the need for a piece-to-piece combination: the fins 32 can be combined with the base 3〇. In addition, as shown in FIG. 4 and FIG. 5, the width D4 of the groove formed by the sandwiched portion 322 of the fin 32 is smaller than the width D5 of the top portion 3020 of the guide rail 302, but larger than the width D6d of the waist portion 3022 of the guide rail 302. Thus, the combination of the fins 32 of the base 32 and the base 30, the movement of the fins 32 along the second direction of extension £2 is limited by the top 3020 of the rails 302. In other words, when the fin 32 is loosely engaged with the base 30, the fin 32 does not disengage from the base 30 in the second extending direction E2. First, in step S36, the guide rail 302 of the base 30 is pressed and deformed to fix the sandwiched portion 322. That is, the main body 3 of the base 30 and the deformed detachable clamping portion 322 of the Korean piece are shown in Fig. H & Fig. Figure 6 is a cross-sectional view showing the portion 322 of the fin 32 before being pressed by the jig 4. FIG. 6B is a cross-sectional view showing the clamped portion 322 of the fin 32 pressed by the jig 4. Fig. 6A and Fig. 6B are shown along the section ρι in Fig. 5. After the fins 32 are combined with the base 30, as shown in FIG. 5, the portion 3020 of the guide rail 3〇2 is positioned above the clamped portion 322 of the fin 32. As shown in Fig. 6a and Fig. 4B, the jig 4 is pressed downward to guide the guide 302, causing the guide rail 302 to be deformed. Since the cross section of the guide rail 302 is T-shaped, the top portion 3020 extends to both sides, and the top portion 3020 is suspended on both sides of the clamped portion 322 of the fin 32, and has no longitudinal support force of 201007438. Therefore, when the side is as shown in Figure 6B

. Therefore, when the top of the top 3020 of the guide rail 302 is shown as two B of the pressing guide 302, the two sides of the top 3020 of the guide rail 302 are forced to clamp the fins 32 up and down with the main body 300 of the base 30 to achieve the effect of stabilizing the fins 32. . Seizure ★, through the above manufacturing process, can quickly and easily manufacture the heat sink 3, the heat sink 3 of the present invention comprises a base 30 and fins. The seat 30 includes a main body 3〇〇 and a guide rail 3〇2, and the guide rail 3〇2 is located at the main body. The fin 32 includes a notch 320 and a sandwiched portion 322, the size of the notch 320 being φ $ j in the cross section of the guide rail 3G2, and the guide rail 3〇2 passing through the notch 320 of the piece. The guide 302 of the base 30 is pressed and deformed, so that the clamped portion 322 of the cymbal 32 is clamped by the main body 3 of the base 30 and the deformed guide rail 302. In addition, depending on the purpose and needs, the material of the base 3 can be aluminum or copper: § However, the material of the fin 32 can also be aluminum or copper. In general, it is most common at present that the base 30 and the fins 32 are made of aluminum. Alternatively, the base 30 is made of copper and the fins 32 are made of aluminum. the complexity. Compared with the prior art, the present invention can easily and quickly manufacture the filaments by the combination of loose fitting of the elements plus the manner of extrusion deformation. Since the notch size of the fin is larger than the cross-sectional dimension of the guide, the heat dissipation fins do not need to be piece-to-piece with the base, but the plurality of heat dissipation fins can be slidably coupled together with the guide rail of the base. Finally, the guide of the base is pressed through the jig, so that the guide is deformed to firmly hold the clamped portion of the fin together with the main body of the base to enhance the bonding force between the fin and the base. Therefore, the manufacturing method of the present invention is simple, and the heat dissipation device is manufactured in a large amount and quickly, thereby saving production cost and reducing assembly.
