摘要： The electrically heated catalytic converter of the present invention has a substrate, for a catalyst, which is formed as a scroll-like cylindrical laminated assembly. The scroll-like cylindrical laminated assembly is formed by laminating a thin corrugated metal sheet and a thin plain metal sheet and winding the laminated metal sheets together around a center electrode. The outermost layer of the laminated assembly is connected to an outer electrode. The corrugated metal sheet has an insulating coating made of an alumina Al₂O₃, and the plain metal sheet has no insulating coating. Local conductive connections are formed between the thin metal sheets by soldering the thin metal sheets using strips of zirconium solder foils interposed between the layers of the thin metal sheets. Since zirconium has larger reducing capability than aluminum, the alumina in the insulating coating is reduced by zirconium and precipitates at the local conductive connections. Therefore, the plain metal sheet and the corrugated metal sheet are electrically connected at the local conductive connections. The solder foils in the respective layers are arranged in such a manner that a strip of solder foil in one layer overlaps with strips of solder foils in adjoining layers only at its ends, and does not overlap with strips of solder foils in the layers next to the adjoining layers when viewed from the radial direction. Since the solder foils in two adjoining layers overlap only by a small area, electric current flows between the local conductive connections concentrates in the overlapped area when electricity is fed to the electrodes. Therefore, hot spots are formed. The resistances of overall electric paths can be easily adjusted by changing the lengths of the solder strips, i.e., distances between the hot spots. Therefore, the amount of electric current flowing through electric paths can be kept at appropriate level.
摘要翻译：本发明的电加热式催化转换器具有用于催化剂的基板，该基板形成为涡旋状的圆柱形层压组件。涡旋状圆筒层叠组件是通过层压薄的波纹状金属片和薄的普通金属片并将层压的金属片卷绕在中心电极周围而形成的。层压组件的最外层连接到外部电极。波纹状金属片具有由氧化铝Al 2 O 3制成的绝缘涂层，并且该普通金属片没有绝缘涂层。通过使用介于薄金属片层之间的锆焊料箔条焊接薄金属片，在薄金属片之间形成局部导电连接。由于锆具有比铝更大的还原能力，绝缘涂层中的氧化铝被锆还原并在局部导电连接处析出。因此，普通金属片和波纹金属片在局部导电连接处电连接。各层中的焊料箔以这样的方式排列，使得一层中的焊料箔条仅在其端部处与相邻层中的焊料箔条重叠，并且不与邻近层中的焊料箔条重叠从径向观察时邻接的层。由于两个邻接层中的焊料箔仅以小面积重叠，因此当电流馈送到电极时，电流在重叠区域中的局部导电连接集中部之间流动。因此形成热点。通过改变焊料条的长度，即热点之间的距离，可以容易地调整整个电路的电阻。因此，流过电路的电流量可以保持在适当的水平。

摘要： An electrically conductive honeycomb body, in particular a catalyst support, can be directly heated electrically and comprises a temperature-dependent resistor for functional control and adjustment. To obtain a suitable electrical resistance between 0.03 and 2 ohms, preferably between 0.1 and 1 ohm, the honeycomb body (12) is subdivided electrically, cross-sectionally and/or axially, by gaps and/or electrically insulating intermediate layers (128) or coatings so that at least one electrical current path having the desired resistance is obtained. A honeycomb body (120) of this type can be used as a catalyst support in motor vehicles and heated before and/or after starting. It can therefore reach the operating temperature required for a catalytic reaction more rapidly, which reduces the exhaust gas emission as early as the starting phase of a motor vehicle. The overall performance of the catalyst can be monitored by continuous or periodic measurement of the electrical resistance of the honeycomb body, and the heating can be suitably adjusted if necessary.
