Abstract
本发明涉及一种带有一个电路路径缩窄结构的扁平电导体(2),其中,一个附加导体(6)沿导体(2)的纵向跨接所述缩窄结构(4)。以这种方式避免在缩窄结构的区域中的过热点。
Description
技术领域
本发明设计一种扁平电导体,例如一种加热元件,并且特别是一种由金属化(敷金属)的织物、或一种具有碳纤维的织物制成的导体,也包括金属化的箔。
在这种导体中,由于设计原因经常需要在导体横截面导电部分上设置缩窄结构,这样在这些部位上由于电流密度提高会导致不希望的过热,即所谓的过热点(Hot-Spots)。
发明内容
因此,本发明的目的在于,避免扁平电导体中出现这种过热点。
按照本发明,该目的通过一个附加导体达到,该附加导体在所述导体的纵向方向上跨接所述缩窄结构。
该附加导体最好同样是扁平导体,它以平面、最好是以整个平面安置在所述导体上,例如锡(钎)焊上,熔焊上,借助于导电的胶粘剂粘接或缝上,如果导体或附加导体是由织物材料组成的。
附加导体的外轮廓最好被这样选择,使得在所述导体或附加导体中获得尽可能均匀的电流密度。
最好是,该附加导体的外轮廓在一侧是圆形或抛物线形的。
在由设置在扁平导体两侧上的凹槽造成的电流路径的缩窄结构中,两个沿导体纵向伸展的外轮廓可以是圆形或抛物线形的。
最好是,所述附加导体特别是在电流路径的缩窄结构区域中至少与所述导体的一个边缘以一个间距安置。
所述导体本身可以由加热元件组成。
附图说明
以下描述本发明电导体的两个实施例。其中,
图1是一个带有附加导体的扁平电导体的俯视图,一侧示出了缩窄结构,
图2是一个带有附加导体的扁平电导体的俯视图,其中导体两侧有缩窄结构。
具体实施方式
在附图1中示出的扁平电导体2中,在导体2正常宽度的区域5与5’之间有一个电流路径-缩窄结构4,它导致导体2缩窄区域中的电流密度被提高。沿纵向覆盖该区域地在导体2上安置上一个附加导体6,它接收流过导体2的电流的一部分并且这样阻止形成过热点。附加导体6的伸展到所述导体中的外轮廓是圆形或抛物线形的,并且使得在导体2以及附加导体的横截面上产生尽可能均匀的电流分配。
图2示出了一个导体2,它具有在两侧的缩窄结构。这里,附加导体6具有一种两侧为圆形或抛物线形的外轮廓,这样获得大致为小船的轮廓。
通过本发明的附加导体,该附加导体本身不置放在过热点上,例如通过在该部位选择具有低电阻的材料实现,则可以可靠地避免这种电导体中的过热点。
