Embodiment
In order to make those skilled in the art better understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, an embodiment's of the thermal baffle that Fig. 1 is automotive muffler of the present utility model axonometric drawing.For semi-surrounding structure, (thermal baffle of semi-surrounding structure is the curved plate that thermal baffle forms along the circumferential extension of silencing apparatus to the thermal baffle 1 of automotive muffler of the present utility model, two ends are near silencing apparatus and do not connect), this technological scheme is compared compared with prior art, increase the encirclement area of thermal baffle to silencing apparatus, make it stop that thermal-radiating ability increases, and has improved the effect of heat insulation of thermal baffle 1.
With reference to Fig. 2, the utility model does not limit the concrete structure of thermal baffle.In the present embodiment, preferably thermal baffle 1 comprise the first thermal baffle 11, middle thermal baffle 12 and the second thermal baffle 13, the first thermal baffles 11 and the second thermal baffle 13 be positioned in the middle of the both sides of thermal baffle 12, and to the lopsidedness at silencing apparatus place.By increasing the first thermal baffle 11, the second thermal baffle 13, improve the thermal-radiating ability that thermal baffle 1 stops silencing apparatus, improve the effect of heat insulation of thermal baffle 1.And preferably thermal baffle 1 is integrated impact briquetting, and processing technology is simple, easily manufactured.
Further, the preferred aluminium paint metal heat-insulated plate of thermal baffle, compared with the aluminium foil thermal baffle of applying in prior art, structural strength and fixed effect are better, can effectively avoid the distortion of thermal baffle 1 in Vehicle Driving Cycle process; While aluminium paint can improve thermal baffle 1 and distribute thermal-radiating ability, and dispersing thermal-radiating while absorption portion thermal radiation, dissipates by the air-flow at the bottom of car, thereby effectively reduces the heat injury of silencing apparatus to periphery part.The thickness of aluminium paint is preferably near 60 microns or 60 microns within the scope of less positive and negative deviation.
Further, thermal baffle 1 is provided with groove, groove can increase the area of thermal baffle 1 reflection and absorptive thermal radiation, further improve the ability of its transmitting and absorptive thermal radiation, the part of simultaneously protruding between groove has the effect of stiffening rib, also can increase the rigidity of thermal baffle 1 self, to keep the stable of thermal baffle self structure.With reference to Fig. 3, the preferred plan of establishment of groove is: groove comprises multiple groove groupings and multiple square groove 7, multiple groove groupings are along the axial arranging of silencing apparatus, groove grouping comprises the second rectangular slot 3 of the first rectangular slot 2 and perforation vertical with the first rectangular slot 2, and multiple square groove are distributed in described the first rectangular slot 2 and described the second rectangular slot 3 around.This technological scheme is by the setting of multiple groove groupings and square indentations 7, further increase the thermal radiation area of thermal baffle 1, further improve thermal baffle 1 transmitting and the thermal-radiating ability of absorbing silencer, and the result through computer simulation analysis is learnt, the distribution form of this groove can make ability >=85% of thermal baffle 1 transmitting and absorptive thermal radiation, meets heat insulation requirement.
