散热片的制造方法及其结构 The method of manufacturing a heat sink and structure

技术领域 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 invention concerns a manufacturing method and structure of a heat sink, particularly to a far-infrared powder coated on the substrate to form a heat sink manufacturing method and structure having the heat radiation function.

背景技术 Background technique

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 remove 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 heat sinks 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, as well as to improve the integration of multi-functional applications 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。 Therefore, for the heat transfer efficiency of research and development has become the main topic 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 the heat dissipation components or systems in the atmosphere; and a lower thermal resistance can be generally described conditions the fins having high heat dissipation 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。 Generally, the thermal resistance is composed of diffusion resistance inside the convective thermal resistance between the heat sink and the heat sink surface and the atmosphere; in the application, high conductivity material such as copper, aluminum and the like are often used to making fins to reduce diffusion resistance; however, limits the effectiveness of the convective thermal resistance of the heat sink, it can not reach the new generation of the electronic component cooling requirements. 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 material into a single manner 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 surface area of ​​the fins must be increased to facilitate heat dissipation effect, and the gap between the structure can be introduced to improve air convection heat dissipation efficiency, so the use of the fin structure often erected on the base of the fin structure, which can significantly increase the surface area of ​​the fins, but also between adjacent fins by air convection heat. 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, often used fin materials such as aluminum or copper, with high thermal conductivity efficiency of the heat conduction to the outside of the system derive.

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。 In composite applications under thinking, often using a combination of materials to improve the efficiency of the fins, for example, copper, aluminum and low density bonded high conductivity properties of aluminum to copper is applied simultaneously to achieve high efficiency and lightweight heat sink, however, must address the above method has the interface thermal resistance between different materials.

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。 Further, there is a conventional heat dissipation structure bonding with an organic binder material on the far-infrared radiating sheet metal, but because of the large thermal organic binder itself, resulting in increased thermal resistance of heat transfer route, so not have significant cooling effect increase.

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。 Edges, the absence of the present invention can improve the above-described felt, one design, the present invention proposes a reasonable and effective to improve the above-described deletion.

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, far-infrared material normally selected ores, complex and difficult to control chemical composition, containing most of the radioactive heavy metal or rare earth element, rare earth element stimulates the release of far-infrared material; with many far-infrared function inorganic powder body colors may not, in addition to tourmaline, volcanic or moso bamboo, coconut shell was 100 (Celsius temperature TC above, but also with far infrared function. therefore, the present invention must be related to the far-infrared analysis and experiments on materials, e.g., according to the present invention first far infrared materials on various compositional analysis and observed crystal phase, and by the above analysis result, far-infrared material powder was prepared, and the powder having a predetermined infrared emissivity, infrared emissivity of the predetermined will be equivalent to infrared emissivity of the far-infrared material chosen. in this particular embodiment, the powder is a ceramic having a far-infrared emitting material ability

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 clay is 10 to 15 percentage of the weight, the weight percent phyllite 10 to 20, the tourmaline 40 to 50 weight percent, and 5 to 10 weight percent of potassium feldspar, albite weight percent of 5 to 10, weight percent vanadium ores having 5 to 10, weight percent copper oxide and 5 to 10 percentage by weight of organic DK2001 10 composed, crushed, sieved, mixed, stirred , granulation, drying, sintering, crushing, blended, the above composition ratio is only an example only and is not intended to limit the present 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, to coated and bonded to the upper surface of the substrate 11; the plate-shaped workpiece is a preferred substrate ll made of a metal material having good heat conductivity, can effectively heat away 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 step. 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 called a surface treatment or surface processing, and its object is further adjusted into a ho physical or chemical properties of the powder surfaces.

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 wherein a powder coated with the above-described far-infrared emitting capability is formed on the substrate 11, it is necessary for the surface modification of the plurality of jobs for powder to adjust the particle size of the powder, the appearance of the parameter to make it more easily coated on the substrate 11 and having a preferred binding force; on the other hand, by a modification of this step, the powder can be adjusted while the crystalline 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 During the heat treatment, the powder formed crystalline phase most beneficial to the following process, or to the heat dissipation layer 12 having a more

高的散热效率的功效。 Effect of high heat dissipation efficiency. 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 Further, this surface modification step may further include a cladding process, the surface coating of the powder to a shell (not shown), the shell may provide better flow characteristics of the powder (also said lubrication), thereby improving the subsequent cladding step, for example, it may be by plating, electroless plating or chemical conversion treatment, etc. coated shell a lower melting point, the low melting point of the shell layer can be draped over the following coating process than the first powder is melted and forms a fluid-filled gap between the powder, and by increasing the flowability of this powder, the heat dissipation layer to strengthen

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, ll to the upper surface of the substrate

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 exit) of these techniques the powder coated on the substrate 11, and a heat dissipation layer 12 formed 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 process for thermal spraying a powder coated on the substrate 11, coating layer can have a uniform thickness, and the coating layer of infrared radiation (heat dissipation layer 12) to maintain the same in the predetermined infrared powder emissivity; Further, the heat dissipation layer 12 and the substrate using the thermal spraying process can have good adhesion between 11 the 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 the heating source, the coated material is heated to be melted, and the cladding material may be in the form of a wire, rod or powder, and then by the thrust gas spraying molten or semi-molten material technical cladding layer to the surface of the workpiece. 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, the flame may be utilized, such as flame spraying (Fkmespray), high-velocity flame spraying (High velocity oxy-fUel, HVOF) method or the like provided in the power mode, such as plasma spraying (Plasmaspmy) arc spraying (arc spray) process and the like, a step of the far infrared radiation powder material heated to a molten or semi-molten state, and then to a high pressure gas atomization and transporting the molten or semi-molten particles on the surface of the substrate ll , far infrared powder molten or semi-molten particles strike the surface of the substrate ll via a high pressure gas stream to form a flat particles, and the plurality of flat particles of the far-infrared rays through layers of the stack, is further formed by a cooling step thermal spraying heat dissipation layer 12 formed. 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。 Notably, the far-infrared although far infrared materials capable of absorbing thermal energy is converted to more radiation by radiation achieve enhance heat dissipation effect, but the thermal conductivity of the heat dissipation layer 12 is 11 lower than the metal substrate, so that the thickness of the substrate 11, must be within a certain range, resulting in too thick a solid structure (i.e., fins integrally l) reduced thermal conductivity, while increasing the heat radiating effect, but not necessarily a whole has improved cooling capacity. 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 rays in nature, as long as the coated thin layer can be obtained radiating effect, so far infrared coated on the heat dissipating fins should be thinned as much as possible, but the mechanism of far-infrared radiation material from the crystalline structure, too thin the coated film is difficult to obtain excellent crystalline structure, resulting in reduced rates of far infrared radiation, far-infrared rays heat dissipation 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 smaller than the predetermined thickness 100 pM, in order to avoid a too thick coating layer resulting in reduced efficiency of heat transmission, and in this condition the thickness of the crystal structure of up to good 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。 Thermal spraying and prior to the present step, most preferably comprising a pre-treatment procedure, for a main operation and a cleaning step for roughening the surface of the substrate 11. 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 pretreatment process can clean the surface of the substrate 11 and the substrate 11 to increase the contact area of ​​the surface of the particles of molten or semi-molten powder of the far infrared, thus improving the quality of construction of the heat dissipation layer 12 is sprayed. 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 oil, dirt, grease removal using a solvent to remove non-soluble oil, grease, and some of the adhesion of dirt or the like debris, degreasing solvent and the resulting cleaning action can remove the impurity and a substantial increase in adhesion Phi covered with the drape of the workpiece; in order to achieve the wrap film coated with the physical association between the workpiece must be increased roughness of the surface of the substrate 11, when the surface area i.e. improve the surface irregularities of the surface of the substrate 11, so that the state of the molten or semi-molten particles strike the far-infrared powder with the air flow to the surface of the substrate ll, may be higher by the 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 features) to give better bite while improving the surface 11 of the substrate and the heat dissipation layer 12

的键合强度。 Bond 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 Further, conditions of the thermal spraying process mainly pressure and temperature, and can be adjusted according to the parameters far infrared thermal spray powder manufacturing process different melting temperatures, such as changing different angular powder-feeding

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。 Regions of different adjusting the powder into the flame temperature; also, or adjusting the current or a combination of gases, such as the flow ratio of helium, argon, in order to provide better powder melting effect different melting characteristics and the effects 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 built fins constituting a high heat dissipation efficiency is 1, can be tested for the cooling function of the heat dissipation sheet 1, for example, at a fixed heat source for the a heat sink 1 with a conventional functional test of fins; relative the other hand, the bonding strength of the film thickness, and with a far-infrared emissivity of the substrate 11 to make a comprehensive test for the crystal of the heat dissipation layer 12 to to ensure the function and application of a heat sink.

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, to the above-described far-infrared emitting powder having a continuously coated on the substrate 11 to form the heat dissipation layer 12 having a function of far-infrared 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 thermal spraying manner to the workpiece surface dimensions and shape are less restricted, and the thermal spraying layer deposited fast, uniform thickness of the heat dissipation layer 12, so ideally suited to automated manner continuous thermal spraying operation.

本发明从上述步骤后,则可以得到一散热片l,该散热片l包括:一基板11及一藉由热喷涂制程披覆于该基板11表面的散热层12,该散热层12是由具有远红外线放射的粉体所形成,且该散热层12同样具有远红外线放射功能。 The present invention from the above step, a heat sink can be obtained l, l the fin comprising: a substrate 11 and a thermal spray process by a cladding layer 11 on the heat dissipation surface of the substrate 12, the heat dissipation layer 12 is composed of a far infrared radiation powder is formed, and the heat dissipation layer 12 has the same far-infrared emitting function. 请参考图3,故当该散热片1应用于一发热单元(如图 Please refer to FIG. 3, so that when the heat sink is applied to a heat-generating unit 1 (FIG.

综上所述,本发明具有下列诸项优点: In summary, the present invention has the various items of the following advantages:
