Abstract
The utility model discloses a thermal insulation shroud for a three-way catalytic converter. The thermal insulation shroud comprises a shroud body (1) which is in the shape of a tile. The shroud body (1) has a single-layered structure and is made of a hot aluminizing steel plate. The shroud body (1) is 1mm to 1.5mm thick. On the premise that the thermal insulation effect is guaranteed, a conventional shroud body with a three-layered structure is changed to the shroud body with the single-layered structure, so that the structure of the thermal insulation shroud is simplified, the production technology is simplified, the production processes are reduced, the production efficiency is improved, material consumption is reduced, and production cost is reduced. The thermal insulation shroud is smart in design, easy to carry out, and suitable for large-scale production and manufacture.
Description
Technical field
The utility model relates to a kind of automobile component, specifically, relates in particular to the ternary catalyzing unit thermal shield.
Background technique
Ternary catalyzing unit is one of vitals of automobile exhaust system, and its function is that the harmful gases such as CO that vehicle exhaust is discharged are transformed into harmless water, nitrogen and carbon dioxide.Because the exhaust temperature that automobile is discharged is higher, the temperature that will cause ternary catalyzing unit so again because ternary catalyzing unit is good heat conductor, so just causes ternary catalyzing unit rubber parts on every side to wear out, lost efficacy because of high temperature than higher easily.For fear of the generation of above-mentioned situation, just need carry out heat insulation processing to ternary catalyzing unit, the general now way that adopts is at thermal shield of ternary catalyzing unit outer mask.
Like Fig. 1,2 and 3, existing ternary catalyzing unit thermal shield comprises cover body 1, and this cover body 1 is a watt shape structure.Simultaneously; Above-mentioned cover body 1 is three shape structures layer by layer; And constitute by outside hot aluminizing steel plate 1a, inboard hot aluminizing steel plate 1c and middle graphite cake 1b; Wherein the thickness of outside hot aluminizing steel plate 1a and inboard hot aluminizing steel plate 1c is 0.5mm, and the thickness of graphite cake is 1mm, so just can effectively realize heat insulation.For the ease of thermal shield is installed on the ternary catalyzing unit, the lower end of said cover body 1 dual-side is arranged with two journal stirrups 2 is installed, and this installations journal stirrup 2 is to turning up, and has a mounting hole 3 on each installation journal stirrup 2.For reinforced structure intensity, special end face at above-mentioned cover body 1 is formed with stiffening rib 4 through punching press, and this stiffening rib 4 is a fenestral fabric.
Because the cover body 1 of ternary catalyzing unit thermal shield is three shape structures layer by layer, the structure more complicated need just can obtain the cover body 1 of thermal shield through three stacks, punching presses during manufacturing; Manufacturing process is complicated, operation is many; Manufacturing efficiency is low, and cost of production is high, is badly in need of solving the problems of the technologies described above for this reason.
The model utility content
The utility model technical problem to be solved is to provide a kind of ternary catalyzing unit thermal shield, desires guaranteeing under the prerequisite of effect of heat insulation, simplified structure, reduces production costs.
The technological scheme of the utility model is following: a kind of ternary catalyzing unit thermal shield; Comprise cover body (1), this cover body (1) be shaped as a watt shape, it is characterized in that: said cover body (1) is a single layer structure; And processed by the hot aluminizing steel plate, and the thickness (t) of cover body (1) is 1～1.5mm.
The utility model is on the basis of existing structure; Is present single layer structure with cover body (1) by three original shape structural adjustments layer by layer; And process by the hot aluminizing steel plate; And the thickness (t) of cover body (1) is 1～1.5mm, learns through overtesting, and the heat-shielding performance and the existing structure of the utility model are identical.Owing to the single layer structure of this thermal shield, only need just can obtain the cover body of thermal shield during production through a punching press, compare the production technology of existing thermal shield cover body; Simplify production technology greatly, reduced operation, improved manufacturing efficiency; And reduced materials consumption, reduce production costs.
In sum, the utility model is present single layer structure with cover body by three original shape structural adjustments layer by layer under the prerequisite that guarantees effect of heat insulation; Both simplify the structure, simplified production technology like this, reduced production process, improved manufacturing efficiency, can reduce materials consumption again; Reduce production costs; Be skillfully constructed, easy to implement, be suitable for the mass production manufacturing.
The thickness (t) of said cover body (1) is 1mm, and this one-tenth-value thickness 1/10 is of moderate size, and can avoid influences effect of heat insulation because thickness is too small, can prevent meaninglessly with thickness waste material again.
For the ease of this thermal shield is fixed on the ternary catalyzing unit; A side lower end of said cover body (1) is provided with two installation journal stirrups (2) that turn up; Another side lower end of this cover body (1) is arranged with two journal stirrup (2) is installed, and all has a mounting hole (3) on each installation journal stirrup (2).
For reinforced structure intensity, the end face of said cover body (1) is formed with stiffening rib (4) through punching press, and this stiffening rib (4) is a fenestral fabric.
Beneficial effect: the utility model is present single layer structure with cover body by three original shape structural adjustments layer by layer under the prerequisite that guarantees effect of heat insulation, both simplifies the structure, has simplified production technology like this, reduced production process; Improved manufacturing efficiency; Can reduce materials consumption again, reduce production costs, be skillfully constructed; Easy to implement, be suitable for the mass production manufacturing.
