Abstract
公开了使用具有被不同材料处理的多个部分的编织或者机织织物片制造的、用于电气或者电子元件的外壳以及用于制造上述外壳的工艺和材料。
Description
技术领域
本发明涉及一种用于电子元件的外壳。
背景技术
[001]用于电气和电子元件的外壳,除了具有足以支撑内部元件并抵抗外部作用力的机械性能外,在某些情况下还必须提供对电磁辐射的屏蔽,以便保证电子元件的适当功能。在很多情况下,还需要电子外壳易于移除电子装置产生的热量。因为这些原因,外壳常常由金属制成,以提供必要的强度、电磁辐射屏蔽和热量移除能力。然而,金属外壳具有相对较重的缺点,并且如果考虑到加工的话,制造比较昂贵。
[002]因此,需要一种用于电气或电子元件的轻重量外壳,它能够提供对电磁辐射的屏蔽、易于移除热量、并且具有足够的强度来安全地容纳电气或电子元件,还需要有适合的材料和工艺来生产上述外壳。

具体实施方式
[0021]现在参考附图1A和B,示出并描述了根据本发明实施例的制造多材料预浸片10的设备以及方法,其中该多材料预浸片10用于构造电气和电子元件用的外壳。首先使用传输装置12来提供未处理的具有预定长度和宽度的编织或者机织织物片。然后,未处理编织或者机织织物片的预定长度被第一材料、第二材料和可选的第三材料来处理,以制造具有用第一材料处理的第一部分20、用第二材料处理的第二部分30以及如所描述的用可选的第三材料处理的可选的第三部分40的多材料预浸片10。然后,多材料或者织物预浸片10在热辊50之间加固,并被收集到滚轴60以用于进一步的加工。在附图1A和B示出的实施例中,材料作为化合聚合物或者涂覆有聚合物金属膜而被施加,这些聚合物或金属膜随后被熔融并浸入到片中。在附图1C中所示的备选实施例70中,相邻的宽缝模90按顺序分配三种不同材料的热熔体到移动中的未处理的编织或者机织织物片的三个不同部分上,以形成多材料预浸片10的第一部分20、第二部分30和第三部分40。不同材料可以通过所示的齿轮泵80、挤出机或者用于定量泵送的其它手段来加压。
[0022]应该理解的是,为了制造具有所需特性的多材料预浸片10,可使用各种各样的材料来处理该未处理编织或者机织织物片。例如,在一个实施例中,使用能提供电磁辐射屏蔽的材料来处理第一部分20,使用能提供结构完整性的材料来处理第二部分30,以及使用能提供保护性外表面的材料来处理第三部份40。如下面要详细表述的那样,使用具有低粘性以便于混合的环氧树脂来将所需的基质材料施加到未处理的编织或者机织织物片上。
[0023]现在参考附图2,其示出了两个截面图,描述了通过用多材料预浸片来缠绕心轴160而制得的电子机架100的实施例。电子机架100包括设置在可绕轴170旋转的分段心轴160周围的多个层110、120、130、140和150。心轴160被分段成多个部分以方便移除。盖板180设置在心轴160的末端,来为电子机架100的前盖和后盖提供安装表面,并为多材料预浸片提供边界表面。用于锚固线路可移除单元或者电路板的支架190可以插入心轴160。支架190可选地包括延伸穿过电子机架100的第一层110的锚192。
[0024]在附图2所示的实施例中,层110是一个冷壁板。该冷壁板可以由铝或者覆盖有金属的高传导性石墨碳制成。用于冷壁的优选材料例如包括石墨板,如从Momentive Performance Materials公司(美国俄亥俄州Strongsville市)获得的TC1050。考虑到热量管理的需要,电子机架100的其它表面也可以是冷壁。层120是可选的传导性开口泡沫层,例如为可从ERG公司(美国加利福尼亚州奥克兰市)获得的铝泡沫,或者从Poco Graphite公司(美国得克萨斯州Decatur市,)获得的碳泡沫。可选择地,热传导间隙可以包括一系列连接在冷壁层110上的翅片。热传导介质如空气或液体从外部歧管流出,穿过泡沫或者翅片,以移除在电子机架100内的电子器件所产生的热量。
[0025]其他的层130、140和150包括缠绕的编织或者机织织物片,其可以是具有浸渍有不同的基质化合物的多个部分的长的连续的编织或者机织织物片,或者每个都浸渍有不同的基质化合物的两个或多个较短的编织或者机织织物片。适合的未处理纤维组织和织物例如包括平织碳纤维,例如可从Zoltec公司(美国密苏里州Bridgeton市)获得的Panex 30,或者可从A&P Technology公司(美国俄亥俄州西西纳提市)得到的二轴或三轴编织的碳纤维。一种适合的用环氧树脂预浸的商用编织物是可从Entropreg公司(美国俄亥俄州哥伦布市)获得的Entropreg 916。其它合适的机织材料包括玻璃纤维、石墨纤维、陶瓷纤维、矿物纤维(例如,Basaltex,Basaltex-Flocart,Wevelgem,Belgium)和芳香尼龙纤维(美国特拉华州Wilmington市的Dupont公司的Kevlar以及Nomex)。
[0026]为了将需要的基质材料施加到未处理的编织或机织织物片上,使用具有低粘性以方便混合的环氧树脂。适合的环氧树脂例如包括Epon 862树脂和Hexion Specialty Materials制造的Epi-Kure W。可获得许多其它的环氧树脂配方,包括许多用于特殊应用的,这对本领域来说是公知的。用于所需基质材料的应用的其它合适的热固性材料例如包括双马来酰亚胺、酚醛塑料、聚酰亚胺、乙烯基酯以及氰酸酯。
[0027]在附图2所示的实施例中,层130具有高电传导性和/或磁性,目的是为机架内的电子元件提供电磁屏蔽,并且防止内部产生的电磁辐射从机架渗漏出。用于层130的基质成分包括具有高电传导性和/或磁性的薄膜或者添加剂。将要在加固的织物预浸料上放置的合适导体膜是铝箔、纳米纸或者镍纳米链纱,它们中的任何都可以连接到相邻的预浸料层。合适的微粒材料包括:例如,碳纳米纤维,例如Applied Sciences,Inc.(Cedarville,俄亥俄)的PYROGRAFF III纤维;碳纳米管,例如Nanocyl(Sambreville,比利时)的 7000;MetalMatrix Composites(Magma,犹他)的镍纳米链;石墨烯片晶,例如Asbury Carbons(Asbury,新泽西)的Asbury Carbon 4827;Honeywell Aerospace(South Bend,印地安纳)的中空碳微球体;以及E&L Enterprises(Oakdale,田纳西)的短(磨碎的或者1/8英寸)碳纤维,包括镍涂层的这些材料,例如Sulzer Metco(FortSaskatchewan,加拿大)的EF 2901。
[0028]可以获得直径约100nm并且高宽比约150:1到约1500:1的PYROGRAFIII纤维。这些纳米纤维能够以多种方式被加热处理,以产生具有期望特性的纳米纤维,包括使纳米纤维在期望的基质材料中易于分散的氧化。如果需要的话,纳米纤维可以被纺成高度取向的微纤维,正如美国专利6,764,628中所描述的,该专利通过引用整体地结合于本文中。纳米纤维也能够被加工形成致密层,其公知为纳米纸,它具有低电阻(即0.3欧姆-厘米)。
[0029]用于结合到层140的合适的中空碳微球体例如包括使用高温工艺由酚制备的、具有体密度或者振实密度约为0.155g/cc并且尺寸介于约40到55微米的中空碳微球体(Honeywell Aerospace,South Bend,Indiana)。可以使用具有约0.35g/cc的体密度以及约85微米的平均尺寸的玻璃微球(3M,明尼阿波利斯,明尼苏达)。适合的镍纳米链金属基质合成物包括具有约50nm到约2000nm的直径、高宽比约50:1到约500:1的未聚合材料。这些镍纳米链金属基质合成物可在面密度约100g/m2、200g/cm2(0.1欧姆-厘米电阻)以及300g/cm2(0.003欧姆-厘米电阻)的纱中获得。合适的涂镍纤维、包括轴向嵌入到小球中的所述纤维,可以从例如Sulzer Metco(Fort Saskatchewan,加拿大)的卖家出售的多种热塑性树脂中商业获取。这些材料提供约60-80dB的电磁干扰屏蔽,并且具有约1.2-1.4g/cc的密度。适当的金属涂覆的纳米纤维包括涂有银和镍的纳米纤维,可从NanoSperse(Akron,俄亥俄)的热塑性母料中商业获得。磁性金属涂层,例如镍,提供了增强的磁性屏蔽。
[0030]在附图2中示出的实施例中,层140包括用于优化机械性能和/或降低电子机架100的重量的基质成分,其较少考虑或者不考虑增强电磁屏蔽。用于实现上面目的的基质成分不同于在层130和150所使用的成分。这个实施例的层140优选连续地连接到层130和层150。能用来赋于电子机架100所期望的机械性能的合适材料例如包括作为添加剂引入到树脂中的短(磨碎到1/8英寸)碳纤维。中空碳或者玻璃微球体降低了密度,因此降低了重量。在一些情况下,中空微球体能作为能量散逸缺陷来增加韧性。碳微球体有助于电磁屏蔽。如果球体是涂有镍的,那么它们也能够提供增强的电磁屏蔽。
[0031]在附图2中所示的实施例中,层150设计为提供耐用外表面,并且可能由于装饰的原因被染色。这层可以包括基质和设计成提供韧性或者耐磨性的添加剂材料。合适的基质和用于这些目的的添加剂材料例如包括橡胶添加剂如羧基封端丁二烯丙烯腈共聚物以增强环氧树脂的韧性,以及用于环氧树脂的大选择范围的颜色内可获得的色素。加入到环氧树脂中达10体积百分比的铝和石墨粉提供了强度和抗磨性,并且能抵抗阳光照射。上述材料可以从WestSystems(Bay City,密歇根)获得。同样可期望的是,在最直接暴露在火中的层中提供阻燃剂,这在本领域是公知的。对于外部的火,该层就是电子机架的外层,和/或如果火可能来自内部,该层就是最内层。
[0032]现在参考附图3,在其上部显示了心轴160和相对于心轴160预定位的多个元件层。如上文所列,示出了冷壁板110、泡沫层120、心轴160以及旋转轴170。在缠绕多材料预浸片之前,冷壁板110、泡沫层120和具有旋转轴170的心轴160被预放置到框架200内(在附图3的下部示出)。框架200包括空气导管开口210和导管220,其中空气导管开口210易于移除在电子机架100内由电子装置产生的热量,而导管220易于连接被所述实施例中的心轴160所占据的门。所示实施例中的框架200也包括用于锚固线路可移除单元(LRUs)或者电路板的支架190。依赖于框架的深度,支架190或者连接到框架200,或者连接到冷壁板110。框架能用多种材料制备,例如包括压制成型的铝或者复合板,或者注塑成型的化合物。
[0033]现在参考附图4,其示出了框架200,它具有心轴160以及在框架200中相对于心轴160预定位的多个元件层。如上所述,示出了冷壁板110、泡沫层120、心轴160、旋转轴170、框架200、空气导管开口210和导管220。具有心轴160和多个预置的元件层的框架200被多材料预浸片缠绕,以完成电子外壳100的准备。
[0034]现在参考附图5,其为本发明实施例的透视图,描述了用多材料预浸片来缠绕心轴160和多个预置的元件层,以形成电子机架100。如上所述,示出了用第一材料处理的第一部分20、用第二材料处理的第二部分30、用可选的第三材料处理的可选的第三部分40、滚轴60、冷壁板110、泡沫层120、心轴160以及旋转轴170。为了更好地描述内部的缠绕,图中没有示出框架。缠绕方法可以包括如图所示的旋转心轴160。可替代的,心轴可以保持固定,而送料辊组件在一个围绕着心轴的轨道内旋转。在另一个替代方案中,预浸片能够在单一的连续工艺中连续地形成并立即在旋转心轴的周围缠绕。如果编织物被用作片材,被缠绕的编织物的宽度应当能够在缠绕工艺过程中通过送料辊的制动力矩而被控制。增加制动力矩,则增加编织物中的张力并降低编织物的宽度(增加了长度),反之亦然。
[0035]现在参考附图6,示出了根据本发明的电子机架100的一个实施例的分解视图,该电子机架100通过用多材料预浸片来缠绕框架200制得,该框架200具有心轴160以及多个预置的元件层。如上所述,已组装的电子机架包括冷壁板110、泡沫层120、心轴160、支架190、框架200、空气导管开口210和导管220。如前所述,完成制造的电子机架还包括具有高的电传导性和/或磁性的层130、含有用于优化电子机架100的机械性能的基质成分的层140,以及设计用于为电子机架100提供耐用的外部表面的层150。
[0036]现在参考如图7,该图是本发明的电子机架100的一个实施例的分解视图,该电子机架包括用于为电子机架提供加固和避雷电保护的金属带230。如上所述,完成的电子机架100包括冷壁板110、泡沫层120、框架200和导管220。如上所述,该完成的电子机架还包括具有高的导电性和/或磁性的层130(未示出)、含有用于优化电子机架的机械性能的基质成分的层140(未示出),以及设计用于为电子机架提供耐用、装饰的外部表面的层150。如前所述,心轴160从完成的电子机架100上移除,从而使电子部件能够在已完成的电子机架100的空心内部安装。金属带230被固定到电子机架100的外部表面上。金属带230能够用多种材料制成,例如包括铝带。支架可用于将电子机架100连接到任何期望的结构。例如,在航空电子领域中,支架可用于将电子机架100连接到飞行器的机身上,从而为包括在电子机架100内的电子元件提供避雷电保护。金属带230进一步给电子机架100提供了结构支撑和加固。
[0037]附图8示出了具有热量传导的可选实施例的截面图,附图9示出了其的剖视图,所述热量传导由在机架的顶部的和底部的内表面上的高传导性板125实现。在该实施例中,用于EMI屏蔽的铝箔层135设置在外部保护层150和结构层140之间。如截面图中所示的,由电子元件300产生的热量如箭头所示地沿着板310传导,并且通过传导板125而穿过机架的后面或者前面。热量穿过机架壁内的高传导入口320流动,并且被外部支撑框架400带走,外部支撑框架自身可以通过流动的流体129或者通过翅片127的自由对流或者辐射而被冷却,这在太空环境中是有效的。
[0038]应当理解的是,可以改变层的数量和顺序,它们的组成以及它们的功能,以满足特定产品的需求。
[0039]还应当理解的是,心轴缠绕工艺可以用于生产中空结构,该中空结构具有用于任何数量的应用的功能层,包括运动设备,例如撑杆或者高尔夫球棒,并且用于机械和电子元件的外壳,例如航空电子设备的机架。
[0040]下面的例子描述了本发明的特定实施例,并且不作为对目前所公开内容的限制。
示例
[0041]为了描述制造工艺,使用可用的材料制造近似四分之一比例的电子机架。已加工过的机架与附图7中所示的设计相对应,并且在附图10中以透视图示出。心轴(未示出)是由木头制成的4"x4"x4"立方体,被切成两个大约相等的近似矩形的部分。在固化后,切割一个轻微的角度以便于滑动式移除心轴部分;所述两个部分由两块板保持在一起,所述两块板均由四个螺钉来固定。铝框架200由0.0625英寸厚的L型材部分制得,并且沿着心轴延伸0.5英寸,具有薄(0.25英寸)的顶部和底部部分202,它用作缠绕层150的边界。选择框架表面的尺寸以刚好覆盖厚度约为0.15-0.19英寸的缠绕物150。框架的两侧延伸0.75英寸,并且包括用于引入冷却流体的开口210。两块厚度为0.0625英寸的铝板被放置在心轴的侧面,用作冷板110。框架结构使用环氧树脂固定。接着,相邻于冷板地放置两块0.5英寸厚的铝泡沫120,用来为热传导流体提供通道。心轴上的前框架和后框架200是相同的。为了给缠绕预浸料提供均匀的平的表面,在底部表面和顶部表面上的的介于前框架和后框架板之间的0.0625英寸的间隙115由0.0625英寸的厚木板(未示出)填充。在该木板上放置Kapton板117以防止与环氧树脂预浸料粘连。
[0042]预浸料的前4层由Nomex编织物制备,当放平时,它测量约为0.012英寸厚(2层)以及6英寸宽。编织物被拉长以为缠绕物提供所需的4英寸的宽度。单个缠绕物约为17英寸长。环氧树脂基质材料是具有按重量比例100:26混有Epikure W固化剂的Hexcel Epon 862树脂。第一层被浸渍有包括6.1体积百分比PYROGRAF III碳纳米纤维的环氧树脂化合物。接下来的三层由具有19体积百分比的中空碳微球体的环氧树脂构成。包括添加剂的环氧树脂化合物以大约54体积百分数施加到Nomex编织物中。通过分散液体流到编织物上、且随后使用橡胶滚轴来散布和浸渍化合物以覆盖编织物的表面而施加化合物。编织物的被浸渍部分被放置在保持约65℃的热板上。在编织物的每个部分都用化合物浸渍后,它放置在两条Kapton膜带之间并且在辊上被卷紧。
[0043]然后将已浸渍的编织物施加到心轴组件,该心轴组件由框架200(示出表面板)、泡沫层120(此处是铝泡沫板)面板、冷壁板110(此处是铝)、木隔块115以及位于木隔块和缠绕编织物之间的Kapton盖子117组成。心轴缓慢旋转,并且调节编织物上的张力从而获得所需的适合面板间的宽度。首先施加纳米纤维层以提供EMI屏蔽。接下来施加三个微球体层以提供坚固的低密度层。最后的缠绕物105是市售的预浸编织物Entrotech 916,其由40%环氧树脂和12K/tow碳纤维组成。所施加的预浸料厚0.085英寸(两层),宽2.15英寸。通过横向拉伸编织物,使编织物的宽度增加到4英寸,而长度相应地减小。施加一层外部保护层150(此处为Entrotech编织物),以提供结构耐久性。
[0044]为了在固化过程中在缠绕的心轴上施加压力,将硅树脂橡胶条紧紧缠绕在外部的Entrotech编织物周围,并且被旋紧的薄塑料带而保持在位置上。然后,被缠绕的结构在121℃的热空气炉中固化四小时。冷却后,固化的机架很容易从心轴上移开。它具有所期望的轻重量和硬度性能。
[0045]虽然已经介绍和描述了本发明的优选实施例,但是如上所述,在不脱离本发明的精神和范围的情况下能够作出多种变化。例如,可以在装置的缠绕部分中切出开口,以允许进入到机架的内部。因此,本发明的范围不受限于优选实施例所公开的内容。相反,本发明应当参考随后的权利要求而被完全确定。
[0046]本发明实施例的独占性或者所要求保护的权利要求在权利要求书中限定。
