ELECTRICALLY HEATED CATALYST DEVICE AND ITS MANUFACTURING METHOD |
摘要 |
An electrically heated catalyst device includes a catalyst support, a surface electrode disposed on an outer surface of the catalyst support and extending in an axis direction of the catalyst support, a wiring line member including a root section extending in the axis direction of the catalyst support and comb teeth-like wiring lines extending from the root section in a circumference direction of the catalyst support and fixed to the surface electrode, an outer cylinder covering an outer surface of the catalyst support, and a holding member holding the catalyst support and packed between the catalyst support and the outer cylinder, in which the catalyst support is heated by feeding a current through the surface electrode and the wiring line member. A slit extending from an outer edge in the circumferential direction of the catalyst support is formed in the root section of the wiring line member. |

1. An electrically heated catalyst device comprising:
a catalyst support supporting a catalyst; a surface electrode disposed on an outer surface of the catalyst support, the surface electrode extending in an axis direction of the catalyst support; a wiring line member comprising a root section extending in the axis direction of the catalyst support and comb teeth-like wiring lines extending from the root section in a circumferential direction of the catalyst support, the comb teeth-like wiring lines being fixed to the surface electrode; an outer cylinder covering the outer surface of the catalyst support; and a holding member holding the catalyst support, the holding member being packed between the catalyst support and the outer cylinder, wherein the catalyst support is heated by feeding a current through the surface electrode and the wiring line member, and a slit extending from an outer edge in the circumferential direction of the catalyst support is formed in the root section of the wiring line member. |
