Description

具有提高柔性的由陶瓷和/或金属 材料挤压制成的蜂窝体
本发明涉及一种由陶瓷和/或金属材料挤压制成的蜂窝体，该蜂窝体具有许多由隔壁相互隔开、基本上平行延伸的通道。例如，在美国专利US—PS3,853 485中已对这种蜂窝体，尤其是用于内燃机的催化器中的蜂窝体进行过描述。
通常，通过对粉末或颗粒状的陶瓷材料进行挤压、干燥，然后再进行焙烧来制成这种蜂窝体。
近年来，这种制造方法也用于制造可以电加热的导电的蜂窝体，在这种方法中也使用了金属材料或金属和陶瓷材料的混合物。欧洲专利EP—A1—0465184对这种蜂窝体作了描述。为了对这种蜂窝体中的电阻和电流的路径形成影响，还附设有一些槽缝，这些槽缝通常与挤压成型的结构平行延伸。
典型的挤压蜂窝体的通道的横截面形状或者是正方形、矩形，或者是其它的多边形。尤其是在美国专利US—PS3853485中，描述了以各种折线作为横截面的形状，其中，在不同的横截面区域中于每横截面积内设有不同数量的通道。
所有至今已知的挤压蜂窝体都是一样的，即具有通道壁的最佳定向，而这种通道壁的最佳定向使得蜂窝体在此最佳定向方向上的弹性减小。就正方形通道而言，蜂窝体实际上在隔板方向上根本没有弹性，并且典型的六角形蜂窝体的弹性也很小。如US—PS3853485中所示的那样，在不同方向上设置附加壁也不能改善弹性。
除去多年来公知的挤压蜂窝体之外，由片状金属制成的蜂窝体的应用也在日益增加，即利用片状金属的适宜结构和分层布置的方式来制成适宜的蜂窝体。除去暂时利用的、由片状金属螺旋形盘绕的蜂窝体之外，在此期间还公开了许多种弹性明显提高的结构。EP—B—0245736中公开了一种对弹性很重要的原理结构，其中各片状金属层基本上是从中心向外渐开线状地延伸。WO90/03220中公开了一种根据这种原理生产的蜂窝体，在WO90/0717中描述了一种稍有不同的形式。如WO89/07488中所述的那样，由片状金属S形盘绕制成的蜂窝体具有类似的特性，其弹性特性和振动特性均受附加加固层的影响。如WO92/0714所述，这种和类似的结构形式以其弹性表明非常适用于可电加热的蜂窝体。
本发明的目的在于提高挤压蜂窝体的弹性，尤其是其弹性特性在各个方向上应该是没有区别的。这种蜂窝体提高的弹性延长了其在各种热交换负荷下的使用寿命并可使结构，尤其是可加热的蜂窝体具有较高的柔性。
本发明的上述目的由下述措施得以实现，即提供一种由陶瓷和/或金属材料挤压制成的蜂窝体，它具有许多由隔墙相互隔开基本上平行延伸的通道，其中至少在一个外部区域中如此布置并构置所述隔壁，即在穿过蜂窝体的横截面中在径向方向上没有刚性结构和/或在圆周方向没有刚性延伸的支撑结构。在径向方向上的刚性结构使蜂窝体在该方向上是刚性的且会由于在拐角处发生的力而产生断裂的危险。在圆周方向上延伸的刚性结构，即圆形结构同样会增加整个蜂窝体的刚性。因此，避免使用这种结构对于这种蜂窝体的柔性而言是很重要的。尽管如此，至今为止在挤压制成的蜂窝体中还是采用了规则的、对称的结构，这种结构总是存在隔壁的最佳方向。这种结构在这种蜂窝体的内部区域中是无关紧要的，但至少应该在半径的最少为30％，最好大于50％的外部区域中选用一种柔性结构。由于目前挤压机的模具主要是由电腐蚀制成，所以即使在专业界出现各种偏见的原因没有试图实现多边形横截面的其他通道形式的情况下，实际挤压任意模具的通道壁在技术上也是没有问题的。由于挤压制成的蜂窝体一开始相对来说较软，所以至少在重力作用方向上要求一定的刚度还是必要的。尽管如此，在这一点上，现代制造技术几乎可以制造任意形状的通道壁。隔壁的一部分至少是在一个外部区域中于横截面内从内向外弯曲延伸是有利的。此时，隔壁最好是螺旋形或者说尤其是基本呈渐开线形地从内向外延伸。这种形式特别有弹性，而且可以在横截面中均匀地布满隔壁。
有许多种可能的方案可用于通过其它隔壁将在弯曲的隔壁之间的间隔分成通道。但重要的是不要使在弯曲的隔壁之间的隔壁在径向方向上相互形成刚性的板。在弯曲隔壁之间的横板的方向应该适应隔壁的路径。
本发明尤其适用于由金属材料挤压制成的蜂窝体，这种蜂窝体是烧结而成的。本发明对于由金属和陶瓷粉末的混合物经挤压制成的蜂窝体特别重要，在这种蜂窝体中应设置用于电绝缘划分的缝。由于这些缝通常将蜂窝体划分成使流体呈曲折形状地从中流过，所以缝附近的区域是处于特殊的机械受力的，这样弹性的结构形状便带来很大的好处。在本发明的蜂窝体中，缝的路径也可以与弯曲的隔壁相平行，尤其是与螺旋形或渐开线延伸的隔壁相平行。
为了减少这种蜂窝体趋于自激振动的倾向或将对准的力引至确定的位置，还可以利用挤压机的相应造型使隔壁的一部分比要挤压的其它隔壁厚。
由于直着延伸的壁段总是在不同的方向上表现出不同的柔性，所以在挤压的蜂窝体中隔壁基本上仅由弯曲的段构成是特别有利的。对于由各种不同的波浪状片状金属层料卷成的蜂窝体而言，这种形状会自动产生，然而至今未有人考虑以其做为挤压制成的蜂窝体。
在通道本身并未沿着直线布置，而是沿着从内向外的弯线设置时，最好是基本上沿着渐开线状延伸的线设置时，也可以由多边形横截面来增加弹性。如此构成的蜂窝体的弹性与具有沿直线布置的通道的蜂窝体相比明显增加。
在附图中，根据示意表示的蜂窝体表示了本发明的不同的、可能的实施例。图中总体地表示了一个蜂窝体1，它没有在径向方向上延伸的结构且没有约为圆形的刚性结构。通道是沿着从中心2向外延伸呈渐开线状的线3设置的，这些线本身可以构成隔壁3。在这种情况下可以仅用弯曲表面，例如可以用波浪形设置的附加隔壁8构成流通通道4。在另一种实施例中，在渐开线形延伸的隔壁3之间的横板也可是直板9，这样即可构成矩形或菱形横截面的流通通道5。如由板11所示的那样，这种横板的方向应与弯曲隔壁3的走向相适应，由此基本上保证如此构成的通道7的横截面是恒定的。在本发明的蜂窝体中当然也可以采用多边形通道6，但要将壁10设置成使通道不在直线上而是跟随着曲线3。最后还有一种可能，如图所示的那样，在这种蜂窝体中使缝12与弯曲的线3相平行，尤其是为了蜂窝体的电划分。为了导向引入力或影响蜂窝体的振动特性，还可设置加强的隔壁13。
与WO92/02717相应的是，当然可以使弯曲线不是精确的渐开线形，而例如可以在外部区域或内部区域中进一步敞开，这样可以在外部或内部区域中提供不同的通道横截面。
本发明尤其适用于挤压制成的导电的蜂窝体和其中有很高的热交换负荷并由此产生很大的机械应力的场合中。
