Description
本發明係關於一種散熱裝置及其固定元件，特別是一種以固定元件直接與散熱鰭片緊密結合的散熱裝置。The present invention relates to a heat dissipating device and a fixing member thereof, and more particularly to a heat dissipating device in which a fixing member is directly coupled with a heat dissipating fin.
就目前常見的散熱裝置而言，基本的形態多為使用金屬板為吸熱底座，並在吸熱底座上豎立複數個金屬片，以做為散熱鰭片。此種形態的散熱裝置，通常是藉由吸熱底座接觸於欲散熱之電子元件上，例如中央處理器(central processing unit，CPU)和圖形處理器(graphic processing unit，GPU)等電子元件，使電子元件於運作時所散發的廢熱可經由吸熱底座經由熱傳導作用傳遞至複數個散熱鰭片，而後並藉由複數個散熱鰭片與外界空氣交換廢熱，並配合散熱風扇的吹拂將廢熱帶走，以強制熱對流的方式達到使電子元件降溫的目的。As far as the current common heat sinks are concerned, the basic form is mostly to use a metal plate as the heat absorbing base, and a plurality of metal pieces are erected on the heat absorbing base to serve as heat sink fins. The heat dissipating device of this type usually contacts the electronic component to be dissipated by the heat absorbing base, such as a central processing unit (CPU) and a graphic processing unit (GPU). The waste heat emitted by the component during operation can be transmitted to the plurality of heat dissipation fins via the heat transfer base, and then the waste heat is exchanged with the outside air through a plurality of heat dissipation fins, and the waste heat is blown by the cooling fan to The method of forcing thermal convection achieves the purpose of cooling the electronic components.
此外，在習知散熱裝置的製造上，為固定散熱裝置的散熱鰭片，是以螺栓或插銷固定元件串接複數個散熱金屬片上的孔洞，使該等金屬片受到固定元件的推抵及鎖固而結合為無底座的散熱裝置。然而，這種散熱裝置僅單純地以固定元件將複數個金屬片鎖固及推抵的結合方式，容易因散熱鰭片及固定元件間材料的熱脹冷縮或是尺寸公差等因素，而導致在散熱鰭片與固定元件之間存在有空氣間隙，如此將減少金屬片與固定元件之間的接觸面積，而嚴重影響金屬片與固定元件彼此之間的熱傳導作用，進而大幅降低散熱裝置的散熱效率。In addition, in the manufacture of the conventional heat dissipating device, in order to fix the heat dissipating fins of the heat dissipating device, the holes in the plurality of heat dissipating metal sheets are connected in series by bolts or bolt fixing elements, so that the metal sheets are pushed and locked by the fixing elements. Solidly combined as a heat sink without a base. However, such a heat dissipating device simply locks and pushes a plurality of metal pieces by a fixing member, and is easily caused by thermal expansion and contraction of materials between the fins and the fixing elements or dimensional tolerances. There is an air gap between the heat dissipating fin and the fixing element, which will reduce the contact area between the metal piece and the fixing element, and seriously affect the heat conduction between the metal piece and the fixing element, thereby greatly reducing the heat dissipation of the heat sink. effectiveness.
因此，如何改善散熱裝置製造時，於金屬片與固定元件之間的接觸面容易產生隙縫及空氣層而無法緊密接觸，所導致散熱裝置的散熱效果不佳的問題，實為目前相關業者所欲解決的課題之一。Therefore, how to improve the manufacturing of the heat dissipating device, the contact surface between the metal piece and the fixing member is prone to gaps and air layers and cannot be in close contact, which causes the problem of poor heat dissipation of the heat dissipating device, which is currently desired by the relevant industry. One of the problems solved.

在第二實施例中，請參照第6圖至第8圖，並請同時對照第1圖至第4B圖，本實施例的散熱裝置10與第一實施例大致相類似，發明人不在此贅述，惟其不同之處在於，本實施例中各散熱鰭片101、102、103、...、104之穿孔1011、...、1041的孔徑實質上相等，然而固定元件20中本體201第一端2011之截面積實質上小於第二端2012之截面積，亦即本體201呈現梯度的型態， 但第一端2011與第二端2012之截面積仍然與穿孔1011、...、1041之孔徑相匹配，仍以能夠穿設過各穿孔1011、...、1041的截面積為限。此本體201呈梯度的型態主要在避免各散熱鰭片101、102、103、...、104之穿孔1011、...、1041的孔徑因為被固定元件20旋入並擠壓孔壁的時間不同，導致穿孔1011、...、1041的孔徑大小有所差異而無法與固定元件20之本體201達到緊配合的情況，也就是說，如第7圖和第8圖所示，固定元件20中本體201第二端2012較大之截面積係為配合被旋入並擠壓時間最長，以致穿孔1041孔徑較大的散熱鰭片104，相對地，固定元件20中本體201第一端2011較小之截面積係為配合被旋入並擠壓時間最短，以致穿孔1011孔徑較小的散熱鰭片101，此外並配合各彈性部202抵靠於各散熱鰭片104、...、103、102、101之穿孔1041、...、1011的孔壁的反作用力，促使固定元件20之本體201與各散熱鰭片101、102、103、...、104完全貼合並達到緊配合的結合狀態而不會留有空隙。此外，也由於本體201第一端2011與第二端2012的截面積不同，因此，當使用者欲以固定元件20與散熱裝置10的散熱鰭片104、...、103、102、101緊配合時，必須以本體201中截面積較小的第一端2011沿一第一方向W1優先地依序穿設過各散熱鰭片104、...、103、102、101之穿孔1041、...、1011，並透過彈性部202抵靠於各散熱鰭片104、...、103、102、101之穿孔1041、...、1011以及鎖固件204的鎖固，達成如第一實施例所述相同的散熱功效。In the second embodiment, please refer to FIG. 6 to FIG. 8 , and please refer to FIG. 1 to FIG. 4B simultaneously. The heat dissipating device 10 of the present embodiment is substantially similar to the first embodiment, and the inventors do not repeat the above description. The difference is that the apertures 1011, ..., 1041 of the heat dissipation fins 101, 102, 103, ..., 104 are substantially equal in this embodiment, but the body 201 in the fixing component 20 is first. The cross-sectional area of the end 2011 is substantially smaller than the cross-sectional area of the second end 2012, that is, the body 201 exhibits a gradient type. However, the cross-sectional area of the first end 2011 and the second end 2012 still match the apertures of the through holes 1011, ..., 1041, and is still limited to the cross-sectional area through which the perforations 1011, ..., 1041 can be passed. The shape of the body 201 in a gradient is mainly to prevent the apertures of the perforations 1011, ..., 1041 of the heat dissipation fins 101, 102, 103, ..., 104 from being screwed into the wall of the hole by the fixing member 20. Different times, the apertures of the perforations 1011, ..., 1041 are different in size and cannot be tightly fitted with the body 201 of the fixing member 20, that is, as shown in Figs. 7 and 8, the fixing member The larger cross-sectional area of the second end 2012 of the main body 201 is to match the heat-dissipating fin 104 which is screwed in and has the longest extrusion time, so that the hole 10441 has a larger aperture, and the first end of the body 201 of the fixing component 20 is relatively The smaller cross-sectional area is to match the heat-dissipating fins 101 which are screwed in and the extrusion time is the shortest, so that the perforation 1011 has a small aperture, and the elastic portions 202 are matched with the heat-dissipating fins 104, ..., 103. The reaction force of the hole walls of the perforations 1041, ..., 1011 of 102, 101 causes the body 201 of the fixing component 20 to completely fit together with the heat dissipation fins 101, 102, 103, ..., 104 to achieve a tight fit. Bonding status without leaving gaps. In addition, since the cross-sectional area of the first end 2011 and the second end 2012 of the main body 201 is different, when the user wants to fix the heat dissipating fins 104, ..., 103, 102, and 101 of the heat dissipating device 10 with the fixing member 20, When the first end 2011 with a small cross-sectional area of the main body 201 is used, the perforations 1041 of the heat dissipation fins 104, ..., 103, 102, and 101 are preferentially disposed in a first direction W1. . . , 1011 , and through the elastic portion 202 against the perforations 1041 , . . . , 1011 of the heat dissipation fins 104 , . . . , 103 , 102 , 101 and the locking of the locking member 204 , achieving the first implementation The same heat dissipation effect as described in the example.
在第三實施例中，請參照第9圖及第10圖，並請同時對照第 1圖至第4B圖，本實施例的散熱裝置10與第二實施例大致相類似，發明人不在此贅述，惟其不同之處在於，本實施例中各散熱鰭片104、...、103、102、101之穿孔1041、...、1011的孔徑係朝第一方向W1逐漸遞減，亦即穿孔1011的孔徑小於穿孔1041，而本實施例固定元件20之本體201之第一端2011之截面積，仍與第二實施例相同，實質上是小於第二端2012之截面積並與穿孔1011、...、1041的孔徑相配合。In the third embodiment, please refer to Figure 9 and Figure 10, and please refer to the same 1 to 4B, the heat dissipating device 10 of the present embodiment is substantially similar to the second embodiment, and the inventors will not repeat them here, but the difference is that the heat dissipating fins 104, ..., 103 in this embodiment The apertures of the through holes 1041, ..., 1011 of the 102, 101 are gradually decreased toward the first direction W1, that is, the aperture of the through hole 1011 is smaller than the through hole 1041, and the first end of the body 201 of the fixing component 20 of the present embodiment is 2011. The cross-sectional area, still the same as the second embodiment, is substantially smaller than the cross-sectional area of the second end 2012 and cooperates with the apertures of the perforations 1011, ..., 1041.
因此，當使用者以固定元件20沿第一方向W1依序穿設過各散熱鰭片104、...、103、102、101時，係由固定元件20之本體201截面積較小的第一端2011由穿孔孔徑最大的散熱鰭片104開始，依序穿設過散熱鰭片104、...、103、102、101的穿孔1041、...、1011，由於固定元件20之本體201的截面積分別與各散熱鰭片104、...、103、102、101之穿孔1041、...、1011孔徑相配合而有所不同，因此當固定元件20之本體201穿設過上述散熱鰭片104、...、103、102、101後，固定元件20之彈性部202會更加確實地抵靠於各散熱鰭片101、102、103、104...之穿孔1011、...、1041的孔壁，因此有助於使本體201與各穿孔1011、...、1041之間更密合，並透過鎖固件204的鎖合，如第10圖所示，更進一步增加固定元件20與各散熱鰭片101、102、103、...、104的接觸面積，使本實施例中散熱裝置10的散熱功效較前二實施例尤為顯著。Therefore, when the user sequentially passes through the heat dissipation fins 104, ..., 103, 102, and 101 in the first direction W1 with the fixing member 20, the body 201 of the fixing member 20 has a smaller cross-sectional area. The one end 2011 is started by the heat dissipation fins 104 having the largest apertures, and the through holes 1041, . . . , 1011 of the heat dissipation fins 104, . . . , 103, 102, and 101 are sequentially passed through the body 201 of the fixing component 20 . The cross-sectional areas of the heat-dissipating fins 104, ..., 103, 102, 101 are respectively matched with the apertures of the heat-dissipating fins 104, ..., 103, 102, 101, so that the body 201 of the fixing component 20 passes through the heat dissipation. After the fins 104, ..., 103, 102, 101, the elastic portion 202 of the fixing member 20 will more reliably abut against the perforations 1011 of the heat dissipating fins 101, 102, 103, 104... The wall of the hole of the 1041, thus helping to make the body 201 and the perforations 1011, ..., 1041 more closely fit and through the locking of the locking member 204, as shown in Fig. 10, further adding the fixing element The contact area of each of the heat dissipating fins 101, 102, 103, ..., 104 is particularly significant in the heat dissipation device 10 of the present embodiment.
值得注意的是，在上述三實施例所揭露的散熱裝置10中，散熱鰭片101、102、103、...、104及固定元件20的材質皆以包含 但不限於銅、鋁等導熱係數較高的材料所製成，同時散熱鰭片101、102、103、...、104及固定元件20的數目亦不以本發明所揭露的內容為限，本領域具有通常技藝者能夠依據散熱需求和空間考量，自行增減散熱鰭片101、102、103、...、104及固定元件20的數目。此外，為增加固定元件20的導熱效果及提昇穩固性，固定元件20中本體201及各彈性部202可選擇採用一體成型的結構，以避免各彈性部202在藉由穿設、鎖固或銲接等方式結合於散熱鰭片101、102、103、...、104時發生脫落或斷裂的情形。It should be noted that in the heat dissipating device 10 disclosed in the above three embodiments, the materials of the heat dissipating fins 101, 102, 103, ..., 104 and the fixing member 20 are included. However, it is not limited to a material having a high thermal conductivity such as copper or aluminum, and the number of the heat dissipating fins 101, 102, 103, ..., 104 and the fixing member 20 is not limited to the contents disclosed in the present invention. Those skilled in the art will be able to increase or decrease the number of heat dissipating fins 101, 102, 103, ..., 104 and fixing elements 20, depending on the heat dissipation requirements and space considerations. In addition, in order to increase the heat conduction effect of the fixing component 20 and improve the stability, the body 201 and the elastic portions 202 of the fixing component 20 may be selected to adopt an integrally formed structure to prevent the elastic portions 202 from being worn, locked or welded. The manner in which the heat sink fins 101, 102, 103, ..., 104 are combined to fall off or break.
上述本發明之散熱裝置，透過固定元件之彈性部在穿設過各散熱鰭片時，因受壓而對應產生反作用力來緊密地抵靠於各穿孔的孔壁，使得固定元件能夠確實貼合於各散熱鰭片，並透過鎖固件的鎖固，使固定元件與各散熱鰭片達到緊配合的效果，使得散熱鰭片與固定元件間不具有空隙，增加接觸面積，以提昇散熱裝置的散熱效果。In the heat dissipating device of the present invention, when the elastic fins of the fixing member pass through the heat dissipating fins, a reaction force is generated to closely abut against the perforated hole wall due to the pressure, so that the fixing member can be surely fitted. The fixing fins are fixed by the locking fins, so that the fixing component and the heat dissipating fins have a tight fit effect, so that there is no gap between the heat dissipating fins and the fixing component, and the contact area is increased to improve the heat dissipation of the heat dissipating device. effect.
同時，由於彈性部的彈性回復力能夠確實抵靠於穿孔的孔壁，因此亦能夠有效地填補空隙，避免任何因散熱鰭片及固定元件間材料的熱脹冷縮而存在有空氣間隙，使得散熱裝置的散熱效果因此受到影響，進而確實保持散熱裝置在任何環境或溫度中的散熱效果。At the same time, since the elastic restoring force of the elastic portion can surely abut against the hole wall of the perforation, it is also possible to effectively fill the gap and avoid any air gap due to thermal expansion and contraction of the material between the heat dissipation fin and the fixing member. The heat dissipation effect of the heat sink is thus affected, thereby ensuring the heat dissipation of the heat sink in any environment or temperature.
