Description

散熱裝置Heat sink

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的散熱裝置。The invention relates to a heat dissipating device, in particular to a heat dissipating device suitable for heating electronic components.

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，而散熱器的散熱片間等間距設置，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, and the fins of the radiator are equally spaced, so that the dust is concentrated by the cooling airflow. The strong area begins to be blown toward the heat sink by the cooling fan, causing the heat sink to be deposited on the side close to the cooling fan to affect its 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具有一出風口，該散熱風扇於出風口處具有至少一強風區及弱風區，所述散熱器包括對應所述強風區的第一散熱鰭片組及對應所述弱風區的第二散熱鰭片組，所述第一散熱鰭片組由複數第一散熱片排列而成，每相鄰的兩第一散熱片間形成第一氣流通道，所述第二散熱鰭片組由複數第二散熱片排列而成，每相鄰的兩第二散熱片間形成第二氣流通道，每相鄰兩第一散熱片之間的距離大於每相鄰兩第二散熱片之間的距離。A heat dissipating device includes a heat sink and a heat dissipating fan disposed on a side of the heat sink. The heat dissipating fan has 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 radiator The first heat dissipation fin group corresponding to the strong wind region and the second heat dissipation fin group corresponding to the weak wind region, the first heat dissipation fin group is formed by a plurality of first heat dissipation fins, each adjacent A first air flow channel is formed between the two first heat sinks, and the second heat sink fin group is formed by a plurality of second heat sinks, and a second air flow channel is formed between each adjacent two second heat sinks. The distance between the first fins is greater than the distance between each adjacent two fins.

與習知技術相比，該散熱裝置中的第一散熱鰭片組及第二散熱鰭片組分別與強風區級弱風區對應，且每相鄰兩第一散熱片之間的距離大於每相鄰兩第二散熱片之間的距離，從而使散熱風扇由外界吸入的氣流中所帶有的粉塵由第一氣流通道的一側進入到散熱器內，再通過第一氣流通道的導引由第一氣流通道的另一側吹出，進而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 first heat dissipation fin group and the second heat dissipation fin group in the heat dissipation device respectively correspond to the strong wind zone level weak wind zone, and the distance between each adjacent two first heat sinks is greater than each The distance between the adjacent two second fins, so that the dust carried in the airflow sucked by the external fan from the outside enters into the radiator from one side of the first airflow passage, and then passes through the guiding of the first airflow passage It is blown out from the other side of the first air flow passage, thereby preventing the accumulation of dust on the heat sink and affecting the heat dissipation performance.

Each of the flanges 422 includes a first flange 423 adjacent to the wind inlet surface 32 and a second flange 425 adjacent the wind outlet surface 33. The width of the first flange 423 is greater than the width of the second flange 425. In this embodiment, the width of the first flange 423 is twice the width of the second flange 425. Each of the first fins 40 further includes a plurality of third fins 44. Each of the third fins 44 and the first fins 42 are alternately disposed, and are respectively located at one end of each of the first airflow passages 43 near the windward surface 33 and do not extend to the wind inlet surface 32. In this embodiment, each of the third heat dissipation fins 44 is located in the middle of the first air flow passage 43 near the end of the air outlet surface 33, so that the distance between each adjacent two first heat sinks 42 is the first heat dissipation. The distance between the sheet 42 and its adjacent third fin 44 is twice. Each of the third fins 44 includes a body 440 and a flange 442 formed by bending and extending from opposite sides of the body 440. The length of the body 440 extending from the air outlet surface 33 toward the air inlet surface 32 is the same as the length of the body 420 corresponding to the second flange 425. The length and width of the flange 442 of the third heat sink 44 are respectively related to the first heat dissipation. The second flange 425 of the sheet 42 has the same length and width.

該第二散熱鰭片組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。本實施例中，該散熱器30的最外側還分別設有一第二散熱片52，具體實施時，亦可於散熱器30的最外側不設置第二散熱片52。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的相對兩側延伸形成的折邊522，所述折邊522包括第一折邊523及第二折邊525。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：第二散熱片52的第二折邊525的寬度與第一折邊523的寬度相同，且均小於第一散熱片42的第一折邊423的寬度，從而使每相鄰兩第一散熱片42之間的距離大於每相鄰兩第二散熱片52之間的距離。本實施例中，每一第二散熱片52的第一折邊523及第二折邊525的寬度均與第一散熱片42的第二折邊425的寬度相同，從而使每相鄰兩第二散熱片52之間的距離與每一第一散熱片42與其相鄰的第三散熱片44之間的距離相等。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. In this embodiment, a second heat sink 52 is further disposed on the outermost side of the heat sink 30. In the specific implementation, the second heat sink 52 may not be disposed on the outermost side of the heat sink 30. Each of the second heat sinks 52 has substantially the same structure as the first heat sink 42 and includes a body 520 and a flange 522 extending from opposite sides of the body 520. The flange 522 includes a first flange. 523 and second hem 525. The structure of each second heat sink 52 is different from that of the first heat sink 42 in that the width of the second flange 525 of the second heat sink 52 is the same as the width of the first flange 523, and is smaller than the first one. The width of the first flange 423 of the heat sink 42 is such that the distance between each adjacent two first fins 42 is greater than the distance between each adjacent two second fins 52. In this embodiment, the widths of the first flange 523 and the second flange 525 of each second heat sink 52 are the same as the width of the second flange 425 of the first heat sink 42 so that each adjacent two The distance between the two fins 52 is equal to the distance between each of the first fins 42 and the third fin 44 adjacent thereto.

組裝散熱器30時，各第一散熱片42、第二散熱片52及第三散熱片44通過折邊422、522、442與其相鄰的本體420、520、440相抵靠，並通過折邊422、522、442上設有相互配合的卡扣結構（圖未示）而固定連接。所述第一散熱片42的第一折邊423及第二散熱片52的第一折邊523的頂端形成該凹槽31的表面。When the heat sink 30 is assembled, the first heat sink 42, the second heat sink 52, and the third heat sink 44 abut against the adjacent bodies 420, 520, 440 by the flanges 422, 522, 442, and pass through the flange 422. 522, 442 are provided with a matching snap structure (not shown) and fixedly connected. The first flange 423 of the first heat sink 42 and the top end of the first flange 523 of the second heat sink 52 form a surface of the groove 31.

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，由於所述兩個第一散熱鰭片組40分別與各強風區89相對應，第二散熱鰭片組50與弱風區90對應，且每相鄰兩第一散熱片42之間的距離大於每相鄰兩第二散熱片52之間的距離，從而使散熱風扇80由外界吸入的氣流中所帶有的粉塵由第一氣流通道43的入風面32進入到第一氣流通道43內，再通過第一氣流通道43的導引由其出風面33吹出，進而防止粉塵於散熱器30上的堆積而影響散熱性能。另外，由於每相鄰兩第二散熱片52之間的距離與每一第一散熱片42與其相鄰的第三散熱片44之間的距離相等，即散熱器30於出風面33的一側仍保持習知散熱器的散熱片間的標準間距，從而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. The bottom plate 84 and the cover plate 83 are respectively provided with an air inlet 86. The side wall 85 is a scroll wall corresponding to the heat sink 30. An air outlet 87 is opened on one side. 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 90 is formed in the middle of the air outlet 87. Since the two first heat dissipation fin sets 40 respectively correspond to the strong wind zones 89, the second heat radiation fin group 50 corresponds to the weak wind zone 90, and each adjacent The distance between the two first fins 42 is greater than the distance between each adjacent two second fins 52, so that the dust carried in the airflow sucked by the external fan 80 from the outside is ventilated by the first airflow passage 43. The surface 32 enters the first air flow passage 43 and is guided by the first air flow passage 43 to be blown out by the air outlet surface 33, thereby preventing the accumulation of dust on the heat sink 30 and affecting the heat dissipation performance. In addition, since the distance between each adjacent two second heat sinks 52 is equal to the distance between each of the first heat sinks 42 and the third heat sink 44 adjacent thereto, that is, one of the heat sinks 30 on the wind surface 33 The side still maintains the standard spacing between the heat sinks of the conventional heat sink, thereby preventing external debris from entering the heat sink 30 from the air outlet surface 33 of the heat sink 30 and affecting 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，即只包含一個第一散熱鰭片組40對應該強風區89設置，弱風區90對應設有第二散熱鰭片組50。所述第一散熱鰭片組40的結構亦不限於本實施例的情況，其亦可為每相鄰兩第一散熱片42之間的距離大於每相鄰兩第二散熱片52之間的距離，且每一第一散熱片42與其相鄰的第三散熱片44之間的距離不大於每相鄰兩第二散熱片52之間的距離的其他結構。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 air-dissipating 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 first heat-dissipating fin group 40 is disposed corresponding to the strong wind zone 89, which is weak. The wind zone 90 is correspondingly provided with a second heat sink fin set 50. The structure of the first heat dissipation fin group 40 is not limited to the case of the embodiment, and the distance between each adjacent two first heat sinks 42 may be greater than between each adjacent two second heat sinks 52. The distance, and the distance between each of the first fins 42 and the adjacent third fins 44 is not greater than the other structure of the distance between each adjacent second fins 52.
