Embodiment Construction

[0021] see Figure 4 ~ Figure 6 , the appearance structure of the present invention is as Figure 4 As shown, it is composed of an S-shaped inner core 1 and an outer shell 3. The S-shaped inner core 1 is made of overlapping flat sheets 4 and corrugated sheets 5 by the S-shaped rolling method, and the S-shaped inner core 1 is pressed into the The inner side of the cylindrical casing 3 coated with a brazing material is brazed.

[0022] For the diameter of the inner core 1 metal carrier, the flat sheet 4 and the corrugated sheet 5 that are not coated with solder 2 are alternately overlapped (see Figure 5 ) is placed in the S-shaped rolling machine (seeing the application number 200710148010.X patent application), and the S-shaped metal carrier inner core that has been rolled is pressed into the pre-coated brazing material (the brazing material and the described The solder 2 is the same) in the shell 3. Then put the completed metal carrier into a vacuum brazing furnace for b...

Abstract

The invention discloses a high temperature-resistant metal carrier. The high temperature-resistant metal carrier is made by an S-shaped rolling method and is characterized by only coating nickel-based welding powder and a binder on the inner wall of a shell, wherein brazing filler metal is not placed on the inner core of a metal carrier of which the inner core diameter is less than or equal to Phi 40; and the brazing filler metal is placed on an inner core chip of an exceeding part of the inner core of the metal carrier of which the inner core diameter is greater than Phi 40. Due to the adoption of the technical scheme, the inner core can be prevented from being burnt through at a high temperature; a using temperature of the metal carrier is improved; and the manufacturing cost of the metal carrier can be reduced.

Description

technical field [0001] The invention relates to a metal carrier used for an engine exhaust aftertreatment device, in particular to a metal carrier in which brazing material is not placed in the center of the inner core or only placed in a part of the edge of the inner core. Background technique [0002] In order to cope with the upcoming national three emission standards for motorcycles, it is necessary to install an exhaust after-treatment device, that is, a three-way catalytic converter, behind the engine. The three-way catalytic converter is to coat a pre-coating such as alumina on a metal carrier, and add precious metals such as rhodium, palladium, and platinum to the pre-coating to make the harmful gases emitted by the engine carbon monoxide (CO) hydrocarbons (HC) and Nitrogen oxides (NOx) are oxidized and reduced to harmless carbon dioxide (CO2), nitrogen (N2) and water (H2O) by the three-way catalytic converter. [0003] The metal carrier is mainly composed of three ...
