散热片的制造方法及其结构 Manufacturing method and structure of the fins

技术领域 Technical Field

本发明有关于一种散热片的制造方法及其结构,尤指一种将远红外线粉体披覆于基板上以形成具有热辐射功能的散热片的制造方法及其结构。 The present invention relates to a method of manufacturing a heat sink and structure, especially a far-infrared powder coated on the substrate to form a manufacturing method and structure having heat radiating fins.

背景技术 Background

冷却电子组件或将其运作产生的热量的移除始终为电子产业发展的一大障碍,为了解决散热问题,各种不同用途与形式的散热片也随之开发。 Cooling electronic components or to remove the heat generated by its operations is always a major obstacle to the development of the electronics industry, in order to solve the heat problem, a variety of different uses and forms of fins also will be developed. 因应高效能的要求、整合度的提高以及多功能的应用,对于散热的要求也面临极大挑战。 In response to high-performance requirements, improve and versatility of application integration, for the cooling requirements are also facing great challenges. 故对于热量移转效率的研发就成为电子工业的主要课题。 So for the heat transfer efficiency of research and development has become the main subject of the electronics industry.

散热片普遍被使用在将组件或系统的热量散逸在大气之中;而通常可以用热阻较低的条件说明该散热片具有较高的散热效率。 Fins commonly used in heat dissipation of components or systems in the atmosphere; and can usually be explained by the lower thermal resistance of the heat sink conditions with high thermal efficiency. 一般来说, 热阻是由散热片内部的扩散热阻以及该散热片表面与大气环境之间的对流热阻所构成;在应用上,高传导性的材料如铜、铝等常被用以制作散热片以降低扩散热阻;然而,对流热阻则限制了散热片的效能,使其无法达成新一代电子组件的散热要求。 In general, the thermal resistance is constituted by the fins inside the thermal diffusion and convection thermal resistance of the heat sink surface and atmospheric environment; in the application, a highly conductive material such as copper, aluminum and other commonly used Country fins to reduce diffusion resistance; however, limits the effectiveness of the thermal convection heat sink, making it impossible to reach a new generation of cooling requirements of electronic components. 据此,目前市场均着眼于更有效率的散热机制。 Accordingly, the current market are focused on more efficient cooling mechanism.

传统上是利用压铸成型、挤型、锻造或机械加工的方式将单一材料制作成散热片结构。 Traditionally, the use of die casting, extrusion, forging or machining manner making material into a single fin structure. 在外型上,必须提高散热片的表面积以利散热的效果,且结构之间的空隙可以引进空气对流而提高散热效率,故散热片结构常利用直立设置于基座上的鳍片结构,该结构可大幅提高散热片的表面积,更可以利用相邻鳍片之间的空气进行热对流。 In appearance, the need to improve the surface area of the heat sink to facilitate heat dissipation effect, and the gap between the structures can be introduced into the air flow and improve thermal efficiency, so often used fin structure erected on the base of the fin structure that can significantly increase the surface area of the fins, but also the use of air between the adjacent fin heat convection. 另一方面,散热片常选用铝或铜等材料,以高传导性的热传导方式将热量有效率地导出于系统之外。 On the other hand, the fins are often used materials such as aluminum or copper with high conductivity thermal conduction heat efficient export outside the system.

而在复合材料应用的思维之下,常使用多种材料的组合以提高散热片的工作效率,例如将铜、铝材料接合以同时应用铜的高传导性及铝的低密度特性来达成效率高且质轻的散热片,然而上述方法却必须解决不同材料之间的接口热阻的问题。 And under the thinking composites, often using a combination of a variety of materials to improve the efficiency of the heat sink, such as copper, aluminum copper bonding applications simultaneously high conductivity and low density properties of aluminum to achieve high efficiency and lightweight heat sink, however, must address the above-described method has the interface thermal resistance between different materials problem.

另外,也有习知的散热结构是利用有机黏结剂黏结远红外线材料于金属散热片上,但因为有机黏结剂本身的热阻大,导致热传途径的热阻增加,故散热效果并不会有明显的增加。 In addition, there are conventional cooling structure is the use of an organic adhesive bonding the far-infrared material to a metal heat sink, but because the thermal resistance of the organic binder itself, leading to increased heat transfer resistance pathways, so the cooling effect does not vary significantly It increases.

缘是,本发明人有感上述缺失的可改善,提出一种设计合理且有效改善上述缺失的本发明。 Edge, the present inventors have felt the lack of the above can be improved, proposes a well-designed and effective improvement of the present invention described above missing.

6可将远红外线材料直接披覆结合(或称披镀)于一基板ll的表面而形成一散热层12,且该基板11与该散热层12则建构成一高散热效率的散热片l,其制造方法包括如下步骤: 6 can be combined with far infrared material is directly coated (or Phi plating) on the surface of a substrate to form a heat ll layer 12 and the substrate 11 and the heat dissipation layer 12 constitute a build thermally efficient heat sink l, which method comprises the steps of:

步骤(一):以远红外线材料为基础,并制备上述远红外线材料的粉体单元。 Step (a): beyond the infrared-based materials, and the preparation of the far-infrared material powder unit. 一般来说,远红外线材料常选自矿石,且化学组成复杂不易控制,大部分含有放射性稀土族元素或重金属,稀土族元素可剌激材料的远红外线释放;具远红外线功能无机物很多,粉体颜色不一定,除电气石、火山岩或将孟宗竹、椰壳经摄氏100(TC以上高温,也具远红外线功能。故本发明中必须先针对远红外线材料进行相关分析及实验,例如, 本发明先就各种远红外线材料进行成分分析及晶相观察,并藉由上述分析结果,制备远红外线材料的粉体,而该粉体具有一预定红外线放射率, 该预定的红外线放射率会等同于所选择的远红外线材料的红外线放射率。在本具体实施例中,该粉体是由具有远红外线放射能力的陶瓷材料 Generally, the material is often selected from far infrared ore and the chemical composition is complex and difficult to control, most containing radioactive rare earth elements or metals, rare earth elements can stimulate the release of far-infrared materials; with far infrared function many inorganic powder the color is not necessarily, in addition to tourmaline, volcanic or Moso bamboo, coconut shell by Celsius 100 (TC temperature above, but also with far infrared function. Therefore, the present invention must be far-infrared materials for correlation analysis and experiments, for example, the present invention first on a variety of far infrared material composition analysis and observation of crystalline phase, and by the results of the above analysis, the preparation of the far-infrared material powder, and the powder has a predetermined rate of infrared radiation, infrared radiation the predetermined rate will be equal to the infrared emissivity far-infrared selected material. In this particular embodiment, the powder is made of a ceramic material having a far-infrared radiation capacity

所制成,例如该陶瓷材料为黏土混合而成,它由重量百分比10至15的黏土、重量百分比10至20的千枚岩、重量百分比40至50的电气石、 重量百分比5至10的钾长石、重量百分比5至10的钠长石、重量百分比5至10的钒钛矿石、重量百分比5至10的氧化铜以及重量百分比10 的DK2001有机物所组成,经过粉碎、过筛、混合、搅拌、造粒、烘干、 烧结、粉碎,调和而成,但上述组成比例仅为举例之用,并非用以限制本发明。 Made, for example, the ceramic material is a mixture of clay, which consists of 10 to 15 weight percent of clay, phyllite weight percent of 10 to 20, 40 to 50 wt% of tourmaline, 5-10 weight percent of potassium feldspar, albite weight percent of 5 to 10, weight percent vanadium and titanium ore 5-10, and 5-10% by weight of copper oxide and 10 weight percent organic DK2001 consisting, after crushing, sieving, mixing, stirring , granulation, drying, sintering, crushing, reconcile, but the proportion of the above composition of example only, and are not intended to limit the invention. 上述组成成分所形成的粉体,即可用以披覆且结合于该基板11 的表面上;该基板ll最佳为一金属材料所制成的板状工件,其对热具有良好的传导性,能有效的将热导出于系统之外。 Powder composition formed above can be used to drape and bonded to the upper surface of the substrate 11; the substrate plate-like workpieces ll most preferably made of a metallic material, which has good thermal conductivity, can effectively heat exported to outside the system.

步骤(二):将该粉体进行表面改质的步骤。 Step (b): the powder surface modification steps. 本步骤又称表面处理或表面加工,其目的在于更进一歩的调整该粉体表面的物理或化学特性。 This step is also known as surface treatment or surface machining, which aims more into a ho adjustment of the powder surface physical or chemical properties.

7由于本发明在于将上述的具有远红外线放射能力的粉体披覆成型于该基板11上,故必须针对该些粉体进行表面改质的作业,以调整该粉体的粒径、外观的参数以使其更容易地披覆于该基板11且具有较佳的结合力; 另一方面,藉由此一改质步骤,可同时调整该粉体的晶相,例如利用一 7 Since the present invention is that the powder coated with far infrared radiation capacity of the above-mentioned 11 formed on the substrate, it must be a job for surface modification that some powder, to adjust the particle size of the powder, the appearance of parameter to make it easier to drape to the base plate 11 and having a preferred binding force; on the other hand, by a modification of this step, the powder can be adjusted while the crystal phase, for example using a

热处理过程,使粉体晶相形成最利于后续制程,或使该散热层12具有更 Heat treatment process, so that the powder phase formation processes most conducive to follow-up, or so that the heat dissipation layer 12 has more

高的散热效率的功效。 High thermal efficiency effect. 再者,此一表面改质步骤更可包括一披覆制程, 以在该粉体的表面披覆一壳层(图未示),该壳层可以提供该粉体较佳的流动特性(亦称润滑性),进而提高后续披覆步骤的进行,举例来说,可利用电镀、无电镀或化成处理等方式披覆一熔点较低的壳层,该低熔点的壳层可以在以下的披覆过程中较该粉体为先熔化,并形成一流体充填于粉体之间的空隙,而藉由此一粉体流动性的增加,即可强化该散热层 Furthermore, such a surface modification step may further comprise a cladding process, the surface coating of the powder to a shell (not shown), the shell can provide a better flow properties of the powder (also said lubrication), thereby increasing the drape subsequent step, for example, can be used electroplating, electroless plating, or chemical treatment, etc. of a low melting point coated shell, the shell can be a low melting point below the draped The powder coating process than the first melt and form a fluid filled in the gap between the powder and the powder by this increased mobility, to strengthen the radiating layer

12的特性。 Characteristics 12.

步骤(三):披覆该粉体于一基板ll的表面,以在该基板ll表面上 Step (c): The powder coated on the surface of a substrate ll to ll on the substrate surface

形成一散热层12。 A heat dissipation layer 12 is formed. 本发明是利用热喷涂(thermal spmy,亦称热熔喷或热熔射)的技术将该些粉体披覆于该基板11上,并于该基板11上成型一散热层12。 The present invention is the use of thermal spraying (thermal spmy, also known as hot melt blown or melt shot) technology the some powder coated on the substrate 11, and forming a cooling layer 12 on the substrate 11. 该热喷涂制程进行粉体披覆于该基板11上,可使披覆层具有一均匀的厚度,且该披覆层(散热层12)保有的红外线放射率相同于该粉体的该预定红外线放射率;另外,利用上述的热喷涂制程可使该散热层12与基板11之间具有良好的附着性,使散热效果更佳。 The thermal spray process carried powder coated on the substrate 11, can cladding layer having a uniform thickness, and the cladding layer (thermal layer 12) to maintain the same rate of infrared radiation in the predetermined infrared of the powder emissivity; In addition, with the above-described thermal spray process allows the heat sink 12 and the substrate layer having a good adhesion between the 11, so that a better cooling effect.

热喷涂技术是藉由加热源的加热,将欲披覆的材料加热熔融后,而该披覆材料可以为线材、棒材或粉末的形式,再藉由气体的推力将熔融或半熔融材料喷涂至加工件表面形成披覆层的技术。 Thermal spraying technology is heated by a heating source, the desire coated material after heating and melting, and the cladding material may be in the form of wire, rod or powder, and then by the thrust gas spraying molten or semi-molten material to the workpiece surface technology cladding layer. 在本发明的实施例中,可利用火焰燃烧,如火焰熔射(Fkmespray)、高速火焰熔射(High velocity oxy-fUel, HVOF)等方式或电能提供的方式,如电浆熔射(Plasmaspmy)、电弧熔射(Arc spray)等制程,将步骤一的远红外线材料的粉体加热至熔融或半熔融状态,再以高压气流雾化并输送上述熔融态或半熔融颗粒于该基板ll的表面,熔融态或半熔融颗粒的远红外线粉体经由高压气流撞击该基板ll表面,以形成扁平的颗粒,而该些扁平的远红外线颗粒则经一层一层的堆栈,再经由冷却步骤形成一热喷涂成型的散热层12。 In an embodiment of the present invention may be utilized flame, such as flame spraying (Fkmespray), high velocity flame spraying (High velocity oxy-fUel, HVOF), etc. or the electric energy supplied, such as plasma spraying (Plasmaspmy) arc spraying (Arc spray) and other processes, will step far infrared material powder is heated to a molten or semi-molten state, and then to the high-pressure gas atomization and transporting the molten or semi-molten particles to the surface of the substrate ll far infrared powder molten or semi-molten particles strike ll surface of the substrate via high-pressure air to form a flat particles, and that these particles are flat far-infrared through layers of the stack, and then forming a via the cooling step Thermal spray-cooling layer 12. 值得注意的是,远红外线材料虽能吸收热能转换成更易辐射的远红外线,以辐射方式达到加强散热的作用,但该散热层12的热传导率比金属基板11为低,使该基板11的厚度必须在一定范围内,膜厚过厚造成固态结构(即整体散热片l)的热传导降低,虽然增加热的辐射效果,但整体的散热能力未必有所提升。 It is worth noting, though far-infrared material capable of absorbing more heat energy is converted into radiation of far infrared radiative cooling to achieve the strengthening of the role, but the thermal conductivity of the heat dissipation layer 12 is lower than the metal substrate 11, so that the thickness of the substrate 11 must be within a certain range, the film thickness is too thick resulting in a solid-state structure (i.e., integral fins l) of reduced thermal conductivity, although the increase in heat radiation effect, but the overall cooling capacity may not be improved. 远红外线本质为光线,只要披覆薄薄一层即可得到辐射效果,因此散热鳍片上的远红外线披覆应尽可能薄化, 但远红外线材料的辐射作用的机制来自于结晶结构,太薄的披覆膜层不易得到良好的结晶结构,造成远红外线放射率降低,因此远红外线材料的散热层12也有一下限厚度。 Far infrared nature of light, as long as you can get coated with a thin layer of radiation effects, so far infrared coated fins should be as thin as possible based on, but the mechanism of far infrared radiation material from the crystal structure, thin The coated film is not easy to obtain good crystalline structure, resulting in a far-infrared emissivity decreased, and therefore the far-infrared radiating material layer 12 also has a lower limit thickness. 在本实施例中,该散热层12具有一均匀的预定厚度H,该预定厚度H小于100pm,以避免太厚的披覆层造成热传导效率的降低,且在该厚度条件下,结晶结构可达良好的远红外线辐射效果。 In the present embodiment, the heat dissipation layer 12 having a predetermined uniform thickness H, H is less than the predetermined thickness 100pm, in order to avoid too thick cladding layer causes reduced heat transfer efficiency, and in this thickness condition, the crystalline structure of up to excellent far-infrared radiation effect.

而在本热喷涂步骤之前,最佳地包括一前处理程序,其主要针对该基板11的表面进行一清洁动作及一表面粗化的步骤。 And before the step of the thermal spraying, most preferably comprising a pre-processing program for the main surface of the substrate 11 is a cleaning operation and a surface roughening step. 该前处理制程可以清洁该基板11的表面并且提高基板11的表面与该熔融态或半熔融颗粒的远红外线粉体的接触面积,进而提高该散热层12的热喷涂施工质量。 The pre-treatment process to clean the surface of the substrate 11 and increases the contact area of the surface of the substrate 11 with the molten or semi-molten particles of far infrared powder, thereby improving the quality of the thermal spray layer 12 of heat dissipation. 该清洁步骤在于去除该基板11表面的水分、氧化膜或其它油脂、污垢等, 利用除脂溶剂去除非溶性的油污、油脂,及一些黏附的污垢或碎屑等, 而除脂溶剂所产生的洗涤作用可以清除上述杂质并大幅提高披覆膜与被披覆工件的结合力;另外,为了达成该披覆膜与被披覆工件之间的物理结合,必须提高该基板11表面的粗度,亦即提高基板11表面的表面积与表面的不规则形状,使上述的该熔融态或半熔融颗粒的远红外线粉体随着气流撞击至该基板ll表面时,可藉由较高粗度的表面(凹凸不平的 This cleaning step is to remove the water surface of the substrate 11, an oxide film, or other grease, dirt, etc., in addition to the use of lipid solvent to remove non-soluble oil, grease, dirt, and some adhesion or the like debris, grease removal solvent and the resulting cleaning action can remove the impurity and significantly improve the adhesion Phi covered with the drape; in addition, in order to achieve the Phi covered with the drape physical bond between the workpiece, the need to improve the surface roughness of the substrate 11, When that is increase the surface area of an irregular shape and surface of the substrate surface 11, so that the above-mentioned molten or semi-molten particles strike the far infrared powder with the airflow to ll surface of the substrate, it can be relatively high surface roughness (uneven

表面特征)而得到较佳的咬合性,同时提高该基板11表面与该散热层12 Surface characteristics) obtained by the preferred bite while improving the surface of the substrate 11 and the heat sink layer 12

的键合强度。 The bonding strength.

再者,该热喷涂制程的条件主要为压力和温度,且可根据不同熔融温度的远红外线粉体调整热喷涂制程的参数,例如改变不同的送粉角度 Furthermore, the thermal spray process conditions of pressure and temperature for the main and far infrared powder can be adjusted according to the thermal spraying process parameters different melting temperatures, e.g., change to a different angle of the powder feed

调整该粉体进入不同火焰温度的区域;亦或是调整电流或是气体的组合, 如氦气、氩气的流量比例,以提供不同熔点特性的粉体较佳的熔融效果及热喷涂效果。 Adjustment of the powder into the flame region different temperatures; also adjusting the current or gas, or combination of, such as the flow ratio of helium, argon, in order to provide better powder melting effect different melting characteristics and the effect of thermal spraying.

而在上述的步骤之后,该基板11与该散热层12则建构成一高散热效率的散热片1,可针对该散热片1的散热功能进行测试,例如在一固定热源的条件下,针对该散热片1与传统散热鳍片进行一功能测试;另一方面也可针对该散热层12的晶相、膜厚、远红外线放射率及与该基板11 的黏结强度做一全面性的测试,以确保该散热片1的功能与应用。 And after the above steps, the substrate 11 and the heat dissipation layer 12 constitute a build thermally efficient heat sink 1, can be tested against the heat sink cooling function 1, for example, under conditions of a constant heat source for the 1 and the conventional heat sink fins conduct a functional test; the other hand, relative, thickness of bond strength, far infrared radiation rate and the substrate 11 to make a comprehensive test against the grain of the heat dissipation layer 12 to Ensure that the heat sink function and application 1.

另一方面,本发明的制造方法也可应用于一连续的热喷涂制程,以将上述的具有远红外线放射的粉体连续披覆于该基板11上以形成具有远红外线功能的散热层12的散热片1。 On the other hand, the manufacturing method of the present invention can also be applied to a continuous thermal spray process, with the aforementioned powder having a far-infrared radiation continuously coated on the substrate 11 to form a layer having a far-infrared heat function 12 1 fin. 由于热喷涂的制程可以导入冷却空气,故制程温度可以有效降低,同时热喷涂施工方式对于工件表面尺寸形状的限制较小,且热喷涂的膜层堆积速度快、散热层12的厚度均匀, 故非常适合以自动化的方式进行连续性的热喷涂作业。 Since the thermal spraying process can be introduced into the cooling air, so that the process temperature can be effectively reduced, while the smaller thermal spray methods for size and shape of the workpiece surface to limit, and thermal spraying layer deposited fast heat dissipation layer 12 of uniform thickness, it is ideal for automated way continuity thermal spray operations.
