本發明涉及一種散熱裝置,特別涉及一種適用於發熱電子元件散熱的散熱裝置。 The invention relates to a heat dissipating device, in particular to a heat dissipating device suitable for dissipating heat of a heat-generating electronic component.
隨著電子產業的飛速發展,電子元件(如中央處理器)運行速度的不斷提升,運行時產生大量的熱量,使其本身及系統溫度升高,繼而影響其系統的穩定性。為確保電子元件能正常運行,通常在其上安裝一散熱裝置,排出其所產生的熱量。 With the rapid development of the electronics industry, electronic components (such as central processing units) continue to increase in speed, generate a large amount of heat during operation, and increase the temperature of the system itself, which in turn affects the stability of the system. In order to ensure the normal operation of the electronic components, a heat sink is usually mounted thereon to discharge the heat generated by the components.
習知的散熱裝置通常包括一散熱器,並於該散熱器的一側設置一散熱風扇,通過該散熱風扇由外界吸入氣流並吹向散熱器以將其熱量帶走。然而,散熱風扇由外界吸入的氣流中往往會帶有大量的粉塵,且由於散熱風扇吹出的冷卻氣流的強度不等,從而使粉塵集中於由冷卻氣流強的區域開始被散熱風扇吹向散熱器,導致散熱器於靠近散熱風扇的一側被粉塵堆積而影響其散熱性能。 Conventional heat sinks generally include a heat sink, and a heat dissipating fan is disposed on one side of the heat sink, through which the airflow is drawn from the outside and blown toward the heat sink to carry away the heat. However, the airflow from the outside of the cooling fan tends to carry a large amount of dust, and the intensity of the cooling airflow blown by the cooling fan is not equal, so that the dust is concentrated in the area where the cooling airflow is strong and is blown to the radiator by the cooling fan. As a result, the heat sink is accumulated on the side close to the heat dissipation fan to affect the heat dissipation performance.
有鑒於此,有必要提供一種可防止粉塵堆積的散熱裝置。 In view of this, it is necessary to provide a heat sink that prevents dust from accumulating.
一種散熱裝置,包括散熱器及設於該散熱器一側的散熱風扇,該散熱風扇對應散熱器設有一出風口,該散熱風扇於出風口處具有至少一強風區及弱風區,所述散熱器包括靠近散熱風扇的入風面及遠離散熱風扇的出風面,所述散熱器由複數散熱片排列而成, 每相鄰兩散熱片間形成氣流通道,所述散熱器設有對應強風區的切口,所述切口由散熱器最外側的散熱片向內側開設,所述切口由入風面向出風面的方向延伸,所述散熱風扇由出風口吹出的氣流中帶有的粉塵通過所述切口流至散熱器的外部。 A heat dissipating device includes a heat sink and a heat dissipating fan disposed on a side of the heat dissipating fan, wherein the heat dissipating fan is provided with an air outlet corresponding to the heat sink, and the heat dissipating fan has at least one strong wind zone and a weak wind zone at the air outlet, the heat dissipating The device includes an air inlet surface adjacent to the cooling fan and an air outlet surface away from the heat dissipation fan, wherein the heat sink is formed by a plurality of heat sinks. An air flow passage is formed between each adjacent two heat sinks, and the heat sink is provided with a slit corresponding to the strong wind region, wherein the slit is opened to the inner side by the outermost fin of the heat sink, and the slit is directed by the wind entering the wind surface. Extendingly, the dust carried in the airflow blown by the air outlet fan flows through the slit to the outside of the heat sink.

Below the receiving groove, the slit extends in a direction in which the wind inlet faces the wind surface, and the dust contained in the airflow blown by the air outlet through the air outlet flows through the slit to the outside of the heat sink.
與習知技術相比,該散熱裝置中的散熱風扇由出風口吹出的氣流中帶有的粉塵通過所述切口流至散熱器的外部,從而使防止粉塵於散熱器上的堆積而影響散熱性能。 Compared with the prior art, the heat radiating fan in the heat dissipating fan flows the dust in the airflow blown out by the air outlet through the slit to the outside of the heat sink, thereby preventing the accumulation of dust on the heat sink and affecting the heat dissipation performance. .

Each of the first fins 42 includes a body 420 and a flange 422 formed by bending and extending from opposite sides of the body 420.
所述第二散熱鰭片組50由複數第二散熱片52排列而成,每相鄰的兩第二散熱片52間形成一第二氣流通道53。每一第二散熱片52的 結構與第一散熱片42的結構大體相同,其包括一本體520及由本體520的相對兩側彎折延伸形成的折邊522。每一第二散熱片52的結構與第一散熱片42的結構不同之處在於:每一第二散熱片52的本體520於入風面32的一側短於第一散熱片42,且所述本體520的頂端於靠近入風面32的一側向入風面32的方向延伸形成一延伸部523,所述延伸部523於入風面32的一端與第一散熱片42於入風面32的一端相平齊。組裝時,各第一散熱片42的折邊422及第二散熱片52的折邊522與其相鄰的本體420、520相抵靠,並通過折邊422、522上設有相互配合的卡扣結構(圖未示)而固定連接。由於第二散熱片52的本體520於入風面32的一側短於第一散熱片42的本體420,且本體520延伸有延伸部523,從而於各第二散熱鰭片組的底端形成一切口54,所述切口54由本體520與延伸部523圍成。所述切口54大致為方塊狀,所述切口54由第二散熱鰭片組50最外側的第二散熱片52向內側開設,並貫穿所有第二散熱片52。所述切口54開設於收容槽31的下方並與收容槽31相連通。所述切口54由散熱器30的入風面32向出風面33的方向延伸,所述第二氣流通道53連接設於切口54與出風面33之間。 The second heat dissipation fin group 50 is formed by a plurality of second heat dissipation fins 52 , and a second air flow passage 53 is formed between each adjacent two second heat dissipation fins 52 . Each of the second fins 52 The structure is substantially the same as that of the first heat sink 42 and includes a body 520 and a flange 522 formed by bending and extending from opposite sides of the body 520. The structure of each second heat sink 52 is different from that of the first heat sink 42 in that the body 520 of each second heat sink 52 is shorter than the first heat sink 42 on one side of the air inlet surface 32, and The top end of the main body 520 extends toward the air inlet surface 32 to form an extending portion 523 at one end of the air inlet surface 32 and the first heat sink 42 on the air inlet surface. One end of 32 is flush. During assembly, the folded edge 422 of each first heat sink 42 and the folded edge 522 of the second heat sink 52 abut against the adjacent bodies 420, 520, and are provided with interlocking snap structures on the flanges 422, 522. (not shown) and fixedly connected. The body 520 of the second heat sink 52 is shorter than the body 420 of the first heat sink 42 on the side of the air inlet surface 32, and the body 520 extends with an extension portion 523 to form a bottom end of each of the second heat dissipation fin sets. A slit 54 is defined by the body 520 and the extension 523. The slits 54 are substantially in the shape of a square, and the slits 54 are opened inwardly by the second fins 52 on the outermost side of the second fin group 50 and penetrate through all the second fins 52. The slit 54 is opened below the receiving groove 31 and communicates with the receiving groove 31. The slit 54 extends from the air inlet surface 32 of the heat sink 30 toward the wind surface 33, and the second air flow passage 53 is connected between the slit 54 and the wind surface 33.
該散熱風扇80為一離心風扇,其包括一底座81及收容於該底座81內的一葉輪82及蓋設於該底座81上的一蓋板83。該底座81包括一底板84及由底板84周緣向上延伸形成的一側壁85。該底板84及蓋板83上分別設有一入風口86,所述側壁85為一渦形壁,其對應散熱器30的一側開設一出風口87。該側壁85上還設有一向內突出的舌部88。請同時參閱圖4,使用時,所述葉輪82旋轉帶動外界氣流由入風口86進入後由出風口87吹出,該吹出的氣流於出風口87處的兩側分別形成一強風區89,於出風口87的中間形成一弱風區 90。所述散熱器30的第二散熱鰭片組50對應於強風區89,第一散熱鰭片組40對應於弱風區90,由於第二散熱鰭片組50上設有切口54,從而使散熱風扇80由外界吸入的氣流中所帶有的粉塵由切口54流出,防止粉塵於散熱器30的入風面32堆積而影響散熱裝置100的性能。由於切口54僅設於散熱器30的底端,從而既可以保證由入風口86吸入的粉塵由切口54處流出,又能保證散熱風扇80吹出的強氣流由切口54上方的第二氣流通道53的導引流過散熱器30。另外,由於切口54未延伸至散熱器30的出風面33,從而使散熱器30於出風面33仍保持習知的散熱器的結構,可防止外界的雜物由散熱器30的出風面33進入到散熱器30內而影響散熱裝置的性能。 The cooling fan 80 is a centrifugal fan, and includes a base 81 and an impeller 82 received in the base 81 and a cover 83 disposed on the base 81. The base 81 includes a bottom plate 84 and a side wall 85 extending upward from the periphery of the bottom plate 84. An air inlet 86 is defined in the bottom plate 84 and the cover plate 83. The side wall 85 is a scroll wall, and an air outlet 87 is defined on a side corresponding to the heat sink 30. The side wall 85 is also provided with an inwardly projecting tongue 88. Referring to FIG. 4 at the same time, in use, the impeller 82 rotates to drive the external airflow to enter the air inlet 86, and then is blown out by the air outlet 87. The blown airflow forms a strong wind zone 89 on both sides of the air outlet 87, respectively. A weak wind zone is formed in the middle of the tuyere 87 90. The second heat dissipation fin group 50 of the heat sink 30 corresponds to the strong wind region 89, and the first heat dissipation fin group 40 corresponds to the weak wind region 90. Since the second heat dissipation fin group 50 is provided with the slit 54 to dissipate heat. The dust contained in the airflow sucked by the outside of the fan 80 flows out of the slit 54 to prevent the dust from accumulating on the air inlet surface 32 of the radiator 30 to affect the performance of the heat sink 100. Since the slit 54 is provided only at the bottom end of the heat sink 30, it is ensured that the dust sucked by the air inlet 86 is discharged from the slit 54 and the strong air current blown by the heat radiating fan 80 is ensured by the second air flow passage 53 above the slit 54. The guide flows through the heat sink 30. In addition, since the slit 54 does not extend to the air outlet surface 33 of the heat sink 30, the heat sink 30 maintains the structure of the conventional heat sink on the air outlet surface 33, thereby preventing external air bubbles from being blown out by the heat sink 30. Face 33 enters heat sink 30 and affects the performance of the heat sink.
具體實施時,該散熱器30及散熱風扇80的結構不限於本實施例的情況,如散熱風扇80上可以不設有舌部88,從而散熱風扇80只有一個強風區89,即強風區89及弱風區90分別位於散熱風扇80於出風口87處的相對兩側,同時,散熱器30的結構亦對應的改變,即只包含一個第二散熱鰭片組50對應該強風區89設置,弱風區90對應設有第一散熱鰭片組40。 In the specific implementation, the structure of the heat sink 30 and the heat dissipation fan 80 is not limited to the case of the embodiment. For example, the heat dissipation fan 80 may not have the tongue 88, so that the heat dissipation fan 80 has only one strong wind zone 89, that is, the strong wind zone 89 and The weak wind zones 90 are respectively located on opposite sides of the heat dissipation fan 80 at the air outlet 87. At the same time, the structure of the heat sink 30 is correspondingly changed, that is, only one second heat sink fin group 50 is disposed corresponding to the strong wind zone 89, which is weak. The wind zone 90 is correspondingly provided with a first heat dissipation fin set 40.
