The substrate and the fin are integrally molded by aluminum extrusion. However, such a heat sink is limited by the aluminum extrusion process, and it is generally impossible to make the size larger, resulting in a limited heat dissipation area.
有鑒於此,有必要提供一種尺寸較大的散熱裝置。In view of this, it is necessary to provide a heat sink having a large size.

An elongated rib 122 protrudes outwardly from one side 120 of the first substrate 12 . The ribs 122 extend along the longitudinal direction of the side edges 120. The width of the rib 122 gradually increases in a direction away from the side 120. The cross section of the rib 122 is in a diverging pattern in a direction away from the first substrate 12 (see FIG. 4). In this embodiment, the rib 122 has a trapezoidal cross section, and it is understood that the cross section may also be triangular, semi-circular, fan-shaped or other shapes.

Sheet 24. Preferably, in the embodiment, the second heat sink 20 is integrally formed by a process of aluminum extrusion to reduce the manufacturing cost. The second substrate 22 is a rectangular plate body. The second heat dissipation fins 24 are disposed perpendicular to the top surface of the second substrate 22 . These second heat radiation fins 24 are arranged in parallel and spaced apart from each other. An air flow passage 240 is formed between the adjacent two second heat dissipation fins 24. The one side of the second substrate 22 facing the first substrate 12 is recessed inwardly to form an elongated slot 222. The card slot 222 extends along the longitudinal direction of the side edge 220. The card slot 222 is correspondingly complementary to the rib 122. The cross section of the slot 222 is corresponding in shape to the cross section of the rib 122 (see FIG. 4), so that the rib 122 can be The card is inserted into the card slot 222, and the first substrate 12 of the first heat sink 10 and the second substrate 22 of the second heat sink 20 are buckled.
請再次參見圖1至圖4,組裝本發明的散熱裝置時,先將所述第一散熱器10的第一基板12的側邊120面向第二散熱器20的第二基板22的側邊220設置,將第一基板12與第二基板22相錯開,使得所述凸肋122的一端對準卡槽222的一端開口處,再將第一基板12與第二基板22相對滑動,使得凸肋122沿卡槽222滑動並卡置入該卡槽222內,直至第一基板12與第二基板22對齊。此時,第一基板12的側邊120與第二基板22的側邊220相貼合,第一基板12的頂面與第二基板22的頂面對應齊平,第一基板12的底面與第二基板22的底面對應齊平,這樣所述第一散熱器10與第二散熱器20通過凸肋122與卡槽222之間的卡合實現連接。所述第一散熱器10與第二散熱器20連接後,可以通過焊接進一步加固連接及密封二者之間的縫隙。優選地,本實施例中採用氬弧進行焊接,以密封第一散熱器10與第二散熱器20的結合處,防止液體滲入。Referring to FIG. 1 to FIG. 4 again, when assembling the heat dissipating device of the present invention, the side 120 of the first substrate 12 of the first heat sink 10 faces the side 220 of the second substrate 22 of the second heat sink 20 first. The first substrate 12 and the second substrate 22 are offset from each other such that one end of the rib 122 is aligned with the opening of one end of the card slot 222, and the first substrate 12 and the second substrate 22 are relatively slid so that the rib is ribbed. 122 slides along the card slot 222 and is inserted into the card slot 222 until the first substrate 12 and the second substrate 22 are aligned. At this time, the side 120 of the first substrate 12 and the side 220 of the second substrate 22 are in contact with each other, and the top surface of the first substrate 12 is flush with the top surface of the second substrate 22, and the bottom surface of the first substrate 12 is The bottom surface of the second substrate 22 is flush, so that the first heat sink 10 and the second heat sink 20 are connected by the engagement between the ribs 122 and the card slot 222. After the first heat sink 10 is connected to the second heat sink 20, the gap between the joint and the seal can be further strengthened by welding. Preferably, in the embodiment, welding is performed by using an argon arc to seal the joint of the first heat sink 10 and the second heat sink 20 to prevent liquid from penetrating.
綜上所述,本發明的散熱裝置中,所述第一散熱器10與第二散熱器20通過凸肋122與卡槽222之間的卡合實現連接,從而增加整體的散熱面積。並且,第一散熱器10與第二散熱器20是通過卡扣的方式進行固定的,過程較為簡便,從而簡化制程。可以理解地,所述第一散熱器10上可以設置有多個凸肋122(分別形成於第一基板12的各個側邊120處),而與多個第二散熱器20相配合而組合在一起。同理,所述第一散熱器10上也可以同時形成有卡槽222,所述第二散熱器20上也可以同時形成有凸肋122,從而實現第一散熱器10與第二散熱器20的多種組合。而且,該散熱裝置的第一散熱器10與第二散熱器20之間配合牢固,進而確保散熱裝置穩定工作。In summary, in the heat dissipation device of the present invention, the first heat sink 10 and the second heat sink 20 are connected by the engagement between the rib 122 and the card slot 222, thereby increasing the overall heat dissipation area. Moreover, the first heat sink 10 and the second heat sink 20 are fixed by means of snapping, and the process is relatively simple, thereby simplifying the process. It can be understood that the first heat sink 10 can be provided with a plurality of ribs 122 (formed at respective side edges 120 of the first substrate 12), and combined with the plurality of second heat sinks 20 together. Similarly, the first heat sink 10 can also be formed with a card slot 222 at the same time. The second heat sink 20 can also be formed with the ribs 122 at the same time, thereby implementing the first heat sink 10 and the second heat sink 20 . Multiple combinations.
