In the utility model, mutually isolatedly between catalyst construction section inwall and the first catalyst be formed with insulated space, the inlet hole arranged and exhaust port, make in vehicle travel process, ambient air can be communicated with catalyst construction section internal partition heat space, and then is taken out of from exhaust port by heat and dissipate, and then raising radiating effect, reduce catalyst and high-temperature gas redox reflect after heat accumulation, slow down high temperature lacquer ablation phenomenon, extend working life.Meanwhile, inlet hole and exhaust port conveniently carry out spray high temperature lacquer to catalyst construction section inside, to slow down high temperature lacquer ablation phenomenon further.
As optimization, described outlet pipe comprises coaxially sheathed and mutually stays spaced outer tube and interior pipe, lining ring is provided with between outer tube and interior pipe, lining ring inner ring is connected to inner tube outer surface, lining ring outer ring is connected on outer tube wall, lining ring is provided with via hole, and interior tube cavity is exhaust gas channel, and the interior pipe in described catalyst construction section ruptures and described first catalyst two ends are fixedly connected on the interior pipe of breaking part.
Like this, easy to exhaust pipe outside heat insulation, its can make to be vented heat that outer wall of inner tube distributes by pipe in exhaust be vented gap between outer tube and be delivered to catalyst construction section position and discharge.Meanwhile, the installation of the first catalyst is facilitated to fix.
As optimization, described lining ring at least has three, and one is positioned at comb inlet, and another two lay respectively at catalyst construction section end positions.Like this, facilitate the setting of lining ring and product structure intensity can be improved.
As optimization, leave space between the cylindrical shell of silencing apparatus and second catalyst of Qi Nei, muffler outlet place is provided with the tail-hood of annular, and tail-hood offers uropore.Like this, the distributing of heat in convenient suppressor case, simultaneously convenient spraying paint to silencing apparatus enclosure interior.
As optimization, suppressor case outer surface is provided with mounting plate along its length, and the housing outer surface of mounting plate side, to being outside equipped with installation journal stirrup, mounting plate and installation journal stirrup is provided with mounting hole.So convenient installation is fixed, and improves and installs fixing reliability.
As optimization, the outer pipe internal surface of catalyst construction section and inner tube outer surface all spray and are provided with one deck high temperature lacquer.Described suppressor case internal surface also can set up one deck high temperature lacquer.Like this, high temperature lacquer ablation phenomenon is slowed down further.
In sum, it is simple that the utility model has structure, and good heat dissipation effect, can slow down high temperature lacquer ablation phenomenon, the advantages such as long service life.
