Description
本創作係有關一種散熱器,尤指一種用最小體積而達到最大化散熱效能的散熱技術。 This creation is about a heat sink, especially a heat sink that uses the smallest volume to maximize heat dissipation.
按目前所知許多的電子或機械元件或組件,在其運轉過程中都會產生熱,為了避免它們在運轉過程中因熱而降低其效能或是遭致損壞,在製造或設計上都會加裝散熱器或散熱元件,藉由散熱器或散熱元件先將熱傳導而散離電子元件或機械元件,再利用流通的流體做熱交換而將電子元件或機械元件所生的熱自工作環境中移除,進而達到降溫以提高元件的工作效率及避免損壞的目的。目前最常見用於電子元件的散熱器是一種鋁擠型散熱器,其廣泛地應用在各式的電子元件或熱導元件上,例如應用在傳統熱導管、中央處理器(CPU)晶片、個人電腦之基板的散熱器、IC晶片之散熱片或是LED燈座散熱鰭片,或是應用於外殼兼散熱裝置(如音響擴大機外殼)等導熱件上。一般常見之鋁擠型散熱器的結構,如圖9所示,於板片狀的散熱器本體50一正面形成複數個並行的長凸條51,而背面為平整面52,平整面52經導熱膠而密貼在電子元件上以有吸收電子元件所生之熱,經本體50將熱傳導至複數長凸條51,而由複數長凸條51的表面將熱散離至外界,進而達到散熱之目的。然而,前述習知散熱器在利用上,因 其須藉由複數長凸條51來增加散熱面積,加上了為保有足夠散熱體積(本體50加長凸條51的總體積要足夠),須以擠型加工技術來成型,因而會產生后述的諸多缺失:1.只能成型出長條並行的長凸條51散熱結構,無法依需要成型各種不同形狀,例如密佈的圓凸柱,或放射分別的凸條等,因而有適用性不足的缺失;2.擠型加工材料受限於軟質金屬,主要是鋁材,對於一些質地較硬的金屬或是合金,便無法適用,因此有材料選用受限的缺失;3.擠型加工成型後,會產生毛邊,必須做去毛邊的處理,因而有增加加工成本的缺失;4.散熱器本體50一面為平整面52,藉由導熱膠與元件密貼,無空氣熱傳導的作用,僅靠長凸條51的表面來散熱,散熱效能不彰,因而習知產品為了提高散熱而須將體積做大,而體積大不僅大幅增加成本,而且對於現今電子產品逐漸講究縮小尺寸的要求上,實已有不符合需求的缺失。 Many of the electronic or mechanical components or components known to date generate heat during their operation. In order to prevent them from degrading their performance or causing damage due to heat during operation, heat is added to the manufacturing or design. The heat sink or the heat dissipating component is dissipated from the electronic component or the mechanical component by heat conduction or the heat dissipating component, and then the heat generated by the electronic component or the mechanical component is removed from the working environment by using the circulating fluid for heat exchange. In turn, the temperature is lowered to improve the working efficiency of the component and avoid damage. The most common heat sink for electronic components is an aluminum extruded heat sink, which is widely used in various electronic components or thermal conductive components, such as conventional heat pipes, central processing unit (CPU) chips, and individuals. The heat sink of the substrate of the computer, the heat sink of the IC chip or the heat sink fin of the LED lamp holder, or the heat conductive member such as the outer casing and the heat sink (such as the sound amplifier casing). Generally, the structure of the aluminum extruded heat sink is as shown in FIG. 9. A plurality of parallel long ribs 51 are formed on the front surface of the plate-shaped heat sink body 50, and the back surface is a flat surface 52, and the flat surface 52 is thermally conductive. The glue is closely attached to the electronic component to absorb the heat generated by the electronic component, and the heat is transmitted to the plurality of long ribs 51 via the body 50, and the surface of the plurality of long ribs 51 dissipates heat to the outside, thereby achieving heat dissipation. purpose. However, the aforementioned conventional radiator is utilized, because It is necessary to increase the heat dissipation area by the plurality of long ribs 51, and in order to maintain a sufficient heat dissipation volume (the total volume of the body 50 to lengthen the ridges 51 is sufficient), it must be formed by extrusion processing technology, and thus will be described later. Many of the missing: 1. Only the long parallel strip 51 heat dissipation structure can be formed, and various shapes can not be formed as needed, such as densely protruding round pillars or radiating separate ridges, etc., thus having insufficient applicability. Missing; 2. Extrusion processing materials are limited by soft metals, mainly aluminum, for some hard metal or alloy, it is not applicable, so there is a limited lack of material selection; 3. After extrusion molding The burr is generated, and the burr must be processed, so that the processing cost is increased. 4. The heat sink body 50 has a flat surface 52. The heat conductive adhesive and the component are closely attached, and the air heat conduction function is not long. The surface of the ridge 51 is used for heat dissipation, and the heat dissipation performance is not good. Therefore, the conventional product has to be bulky in order to improve heat dissipation, and the large volume not only greatly increases the cost, but also gradually reduces the size of the current electronic products. On request, there does not meet the real needs of the missing.
再者,台灣新型第M292731號『散熱結構』,其係以網狀散熱鰭片設在散熱基座上,雖然可藉由增加散熱面積而提升散熱效果,惟,網狀散熱鰭片並非與散熱基座的平面平行,況且各個網狀散熱鰭片之間非以間隔排列的方式設置,而是以特定角度相互連結,以致會有體積大、佔用空間以及應用範圍受到限制等缺失產生。 Furthermore, Taiwan's new M292731 "heat dissipation structure" is based on a mesh-shaped heat sink fin on the heat sink base. Although the heat dissipation area can be increased by increasing the heat dissipation area, the mesh fins are not cooled. The planes of the pedestals are parallel, and the respective mesh fins are not arranged in a spaced manner, but are connected to each other at a specific angle, so that there is a large volume, a large space, and a limited application range.
台灣新型第M352636號『散熱裝置』,其係以網狀散熱裝置罩設在LED發光元件的正面,雖然網狀散熱裝置除了可以傳導LED發光元件的熱能外,並能讓光源由網狀區域穿射出去,惟,網狀區域多少仍會阻擋光源的穿透率,以致影響LED發光元件的發光效能,此外,網狀散熱裝置為單片式構造,散熱面積仍有所不足,從而影響整體的散熱效能。 Taiwan's new M352636 "heat sink", which is covered by a mesh heat sink on the front side of the LED light-emitting component, although the mesh heat sink can not only conduct the thermal energy of the LED light-emitting component, but also allow the light source to be worn by the mesh region. Shooting out, but the mesh area still blocks the transmittance of the light source, which affects the luminous efficacy of the LED light-emitting element. In addition, the mesh heat-dissipating device has a monolithic structure, and the heat-dissipating area is still insufficient, thereby affecting the overall Cooling performance.
台灣發明第I310298號『散熱器及其製造方法』,其係於薄片狀之金屬板上滾壓出微型凹凸結構,然後透過沖壓加工技術形成凹凸結構的散熱鰭片,再利用散熱鰭片與基板之結合,以得到所需的散熱器。該專利雖然具備導熱的散熱效果,但是其金屬板係屬薄片的結構形態,以致會因體積不足而影響到散熱的比表面積;此外,該專利沖壓加工製成的散熱器必須做除毛邊的工序,以致增加製造工序的複雜程度;不僅如此,該專利散熱鰭片上的凸部體積與凹部容積之間的誤差率大於10%,且凸部外徑與凹部內徑之間的誤差率大於10%;亦即,凸部的體積大於凹部的容積約10%以上,凸部的外徑大於凹部的內徑約10%以上;相較於本新型各凸部的體積幾乎等於各凹部的容積,各凸部的外徑幾乎等於各凹部的內徑,故而二者有著明顯的技術差異。當然,發明第I310298號專利會因體積過小的因素而限制了散熱的比表面積,從而影響到整體的散熱效率。 Taiwan Invention No. I310298 "Radiator and its manufacturing method", which is formed by rolling a micro-concave structure on a sheet metal plate, and then forming a heat-dissipating fin of a concave-convex structure by a press working technique, and then using a heat-dissipating fin and a substrate The combination is to get the desired heat sink. Although the patent has the heat-dissipating heat-dissipating effect, the metal plate belongs to the structural form of the sheet, so that the specific surface area of the heat-dissipation is affected by the insufficient volume; in addition, the heat-dissipating heat sink of the patent must be subjected to the process of removing the burrs. Therefore, the complexity of the manufacturing process is increased; not only that, the error rate between the volume of the convex portion and the volume of the recess on the heat-dissipating fin of the patent is greater than 10%, and the error rate between the outer diameter of the convex portion and the inner diameter of the concave portion is greater than 10%. That is, the volume of the convex portion is greater than about 10% of the volume of the concave portion, and the outer diameter of the convex portion is greater than about 10% of the inner diameter of the concave portion; compared with the volume of each convex portion of the present invention, the volume of each concave portion is almost equal to the volume of each concave portion, The outer diameter of the convex portion is almost equal to the inner diameter of each concave portion, so that there are significant technical differences between the two. Of course, the invention No. I310298 limits the specific surface area of heat dissipation due to the small volume factor, thereby affecting the overall heat dissipation efficiency.
緣是,雖然以沖壓加工技術成型為散熱鰭片的技術特徵已被揭露;惟,直至目前為止,尚未發現有關凸部體積幾乎等於凹部容積且凸部外徑幾乎等於凹部內徑之散熱器的專利或論文被提出,因此,本新型創作人乃積極努力研究,經潛心開發,終於研發出一種實用且功效更為增進的本新型。 The reason is that although the technical features of forming the heat dissipating fins by the press working technique have been disclosed; however, until now, it has not been found that the heat sink of the convex portion volume is almost equal to the concave portion volume and the outer diameter of the convex portion is almost equal to the inner diameter of the concave portion. The patent or the thesis was put forward. Therefore, the creator of this novel is actively researching and researching, and after diligent development, finally developed a new type of utility that is more practical and more effective.

The error rate between the two approaches is zero, that is, the volume T1 of each convex portion 120 is almost equal to the volume T2 of each concave portion 110; and the error ratio between the outer diameter of each convex portion 120 and the inner diameter of each concave portion 110 ( The inner diameter of the concave portion 110 minus the outer diameter of the convex portion 120 is divided by the inner diameter of the concave portion 110 is less than 5%, and preferably the error ratio between the outer diameter of each convex portion 120 and the inner diameter of each concave portion 110 approaches zero. That is, the outer diameter of each convex portion 120 is almost equal to the inner diameter of each concave portion 110. Moreover, the thickness of the heat-generating sheet-like body 100 is greater than the height of the convex portion 120. Preferably, the thickness of the heat-dissipating sheet-like body 100 is reduced by the height of the convex portion 120, and then the thickness of the heat-dissipating sheet-like body 100 is between 10 and 50. %, this can ensure that the convex portion 120 is formed by the displacement of the material of the heat-generating sheet-like body 100 originally located at the concave portion 110, and can ensure that the heat-generating sheet-like body 100 still retains its desired thickness volume.
請配合參看圖1~3及圖7所示為實現本新型第二目的之第二實施例,係對金屬板材10進行沖壓加工成型散熱器片狀本體100,金 屬板材10包含相反的第一面11及第二面12。散熱器片狀本體100具有相同於金屬板材10的第一面11及第二面12,使第一面11上具有複數做為熱導散熱之用的凹部110,第二面12相對於各凹部110的位置處具有複數做為熱導散熱之用的凸部120。各凸部120的體積T1與各凹部110的容積T2之間的誤差率小於5%,且各凸部120的外徑與各凹部110的內徑之間的誤差率小於5%較佳為各凸部120的體積T1與各凹部110的容積T2之間的誤差率趨近於0,亦即,各凸部120的體積T1與各凹部110的容積T2幾乎相等;且各凸部120的外徑與各凹部110的內徑之間的誤差率(小於5%,較佳為各凸部120的外徑與各凹部110的內徑之間的誤差率趨近於0,亦即,各凸部120的外徑與各凹部110的內徑幾乎相等。請再參看圖7所示,各凸部120及各凹部110分別呈階梯狀結構,即凹部110的底部再凹陷出小凹部111,相對該凹部110的凸部120頂部再相對小凹部111的位置處突小凸部121,於此,可以再增加整體的散熱表面積。此外,如圖3所示,係於金屬板材10的表面塗佈至少一層散熱材料20。 Please refer to FIG. 1 to FIG. 3 and FIG. 7 for the second embodiment of the second object of the present invention. The metal sheet 10 is stamped and formed into a heat sink sheet body 100, gold. The slab 10 includes opposing first and second faces 11 and 12. The heat sink sheet body 100 has the same first surface 11 and second surface 12 of the metal sheet 10, so that the first surface 11 has a plurality of recesses 110 for heat conduction, and the second surface 12 is opposite to each recess. The position of 110 has a plurality of convex portions 120 for heat conduction. The error rate between the volume T1 of each convex portion 120 and the volume T2 of each concave portion 110 is less than 5%, and the error rate between the outer diameter of each convex portion 120 and the inner diameter of each concave portion 110 is less than 5%. The error rate between the volume T1 of the convex portion 120 and the volume T2 of each concave portion 110 approaches zero, that is, the volume T1 of each convex portion 120 is almost equal to the volume T2 of each concave portion 110; and the outer portions of the convex portions 120 are The error rate between the diameter and the inner diameter of each recess 110 (less than 5%, preferably the error ratio between the outer diameter of each convex portion 120 and the inner diameter of each concave portion 110 approaches zero, that is, each convex The outer diameter of the portion 120 is almost equal to the inner diameter of each recess 110. Referring to FIG. 7 again, each convex portion 120 and each concave portion 110 have a stepped structure, that is, the bottom portion of the concave portion 110 is further recessed with the small concave portion 111, and The top of the convex portion 120 of the concave portion 110 protrudes from the top portion of the concave portion 111 with respect to the small concave portion 111. Here, the overall heat dissipation surface area can be increased. Further, as shown in FIG. 3, the surface of the metal plate material 10 is coated. At least one layer of heat dissipating material 20.
具體來說,請配合參看圖1~3所示的實施例中,本新型全部凹部110與第一面11投影在一平面上的面積比為1:10~9:10。相對地本新型全部凸部120與第一面11投影在一平面上的面積比為1:10~9:10。前述的設計,可依各個需要散熱的元件之效熱效能需求來做該比例的設計,而無論如何這樣的比例範圍都能確保具有足夠的散熱效能。 Specifically, in the embodiment shown in FIGS. 1 to 3, the area ratio of all the concave portions 110 and the first surface 11 projected on a plane is 1:10 to 9:10. In contrast, the area ratio of all the convex portions 120 and the first surface 11 projected on a plane is 1:10 to 9:10. The foregoing design can be designed according to the thermal efficiency requirements of each component that needs to be dissipated, and in any case such a range of ratios can ensure sufficient heat dissipation performance.
再請配合參看圖1~3所示的實施例中,上述各個凹部110及凸部120可以是圓柱形;或是長條柱形或是多邊柱形;或是如4~6圖所示係呈多個左右上下對稱的L型。凹部110及凸部120的形狀或是分佈的狀態,可依實際需求來設計沖壓模具進行沖壓。 Referring to the embodiment shown in FIG. 1 to FIG. 3, each of the recesses 110 and the protrusions 120 may be cylindrical; or a long column or a polygonal column; or as shown in FIG. It is a plurality of L-shaped symmetrical left and right. The shape of the concave portion 110 and the convex portion 120 or the state of the distribution can be designed by stamping a die according to actual needs.
請配合參看圖1~3所示的實施例中,上述金屬板材10呈厚度較前揭發明第I310298號專利為厚的片狀金屬板材10,此片狀金屬板材10可以是由鋁、銅或是金屬合金所製成。 Referring to the embodiment shown in FIG. 1 to FIG. 3, the metal sheet 10 is thicker than the first invention No. I310298, and the sheet metal sheet 10 may be made of aluminum, copper or It is made of metal alloy.
請配合參看圖8所示的實施例中,金屬板材10係捲繞呈帶狀,此捲繞之帶狀金屬板材10係透過沖壓模具30而可由沖壓加工成型為包含多個連續相接的散熱器,再由裁剪裝置40將連續相接的多個散熱器分別裁剪為多個單體散熱器。於另一種實施例中,可以透過裁剪裝置40將捲繞之帶狀金屬板材10預先裁剪為預定尺寸之單片的金屬板材10,然後透過沖壓模具30對單片的金屬板材10進行沖壓加工,於此,即可將單片的金屬板材10沖壓加工為具有複數個凸部120與複數個凹部110的散熱器。 Referring to the embodiment shown in FIG. 8 , the metal sheet 10 is wound in a strip shape, and the wound strip metal sheet 10 is formed by punching through the stamping die 30 to form a plurality of continuous heat sinks. Then, the plurality of heat sinks that are continuously connected are respectively cut into a plurality of single radiators by the cutting device 40. In another embodiment, the wound strip metal sheet 10 can be pre-cut into a single piece of sheet metal 10 of a predetermined size through the cutting device 40, and then the single sheet metal sheet 10 is stamped through the stamping die 30. Here, the single piece of metal sheet 10 can be stamped into a heat sink having a plurality of convex portions 120 and a plurality of concave portions 110.
此外,必須說明的是,每一凹部110內部空氣有輔助熱傳導的效果,除了散熱器片狀本體100保有足夠的散熱體積及其第二面12與電子元件間有足夠接觸面積之外,由於凹部120具有空氣的輔助熱導功能,故可確實提升散熱的效能。 In addition, it must be noted that the air inside each recess 110 has the effect of assisting heat conduction, except that the heat sink sheet body 100 retains a sufficient heat dissipating volume and a sufficient contact area between the second surface 12 and the electronic component, due to the recess 120 has the auxiliary heat conduction function of air, so it can really improve the heat dissipation performance.
本創作的優點:1、沖壓錯位一體成型,使具足夠厚度體積的散熱器片狀本體100本身具較佳熱傳導效能之外,藉由一體沖壓錯位所形成的凸部120散熱結構,再度增加散熱表面積,使其在最佳小化的體積原則下,能達到最佳的散熱效能;2、凸部120由散熱器片狀本體100位於凹部110位置的原材料沖壓錯位成型,凹部110內壁具熱導面積,內部的空氣具輔助熱導效能,也能使本創作散熱器更增加散熱效能;3、凸部120及凹部110分別形成對應的階梯狀結構,又更能輕易地再大幅增加散熱表面積,尤其凹部110階梯狀結構,讓所需散熱的元件,藉由空氣輔助傳導,而快速地將熱傳遞至凸部120,再由凸部120表面散除至外界;4、縮小化體積具最佳散 熱,可應用於現今強調縮小化的電子產品上,符合時代趨勢潮流;5、一次沖壓成型,無需去除毛邊,簡化製程,降低成本;6、可依所需散熱的產品之形狀需求,沖製成不同形狀的凸部形狀,例如圓柱形分佈,長條狀放射分佈或L型分佈,大幅增進產品的適用性;7、可供帶狀的金屬板材搭配多組散熱器形狀的模具,一次沖壓成型多組散熱,快速輸送、沖壓成型及裁切即可製造出大量的本創作散熱器,可大幅降低成本。 The advantages of the creation: 1. The stamping dislocation is integrally formed, so that the heat sink sheet body 100 having a sufficient thickness and volume has a better heat conduction performance, and the heat dissipation structure of the convex portion 120 formed by the integral stamping dislocation increases the heat dissipation again. The surface area is such that the optimal heat dissipation performance can be achieved under the principle of optimally miniaturized volume; 2. The convex portion 120 is formed by the stamping of the raw material of the heat sink sheet body 100 at the position of the concave portion 110, and the inner wall of the concave portion 110 is heated. The conductive area and the internal air have auxiliary thermal conductivity, which can also increase the heat dissipation performance of the created heat sink. 3. The convex portion 120 and the concave portion 110 respectively form a corresponding stepped structure, and the heat dissipation surface area can be greatly increased. In particular, the recessed portion 110 has a stepped structure, so that the heat-dissipating component is quickly transferred to the convex portion 120 by air-assisted conduction, and then dispersed to the outside by the surface of the convex portion 120; Jia San Heat can be applied to today's electronic products that emphasize downsizing, in line with the trend of the times; 5, one-time stamping, no need to remove the burrs, simplify the process, reduce costs; 6, according to the shape requirements of the product to be cooled, Shapes of protrusions of different shapes, such as cylindrical distribution, strip-shaped radiation distribution or L-shaped distribution, greatly improve the applicability of the product; 7. Available for strip-shaped metal sheets with multiple sets of heat sink-shaped molds, one-time stamping Forming multiple sets of heat dissipation, rapid transfer, stamping and cutting can produce a large number of original heat sinks, which can greatly reduce the cost.
