Backflow, affects engine work.Further, since the exhaust temperature that automobile is discharged is the highest, long working environment can make
Obtain catching device temperature too high, damage the device within catching device, and the solution explosive evaporation being easily caused in catching device, bring
Serious consequence.
Summary of the invention
The purpose of this utility model, it is simply that for solving the problem that prior art exists, and devise a kind of anti-return formula vapour
Tail gas exhaustor, improves radiating efficiency, it is possible to effectively prevent the solution explosive evaporation in catching device, have catching device good
Good defencive function.
The technical solution of the utility model is: a kind of anti-return formula vehicle-exhaust exhaust pipe, including exhaustor body and set
Putting the protection tube in body exterior, described body is hollow pipeline, and its left end is vehicle exhaust inlet end, and right-hand member is car tail
Gas outlet side；The right-hand member of body connects catching device, and the other end of catching device connects tail gas escape pipe；A left side in described chamber body
End is provided with several sideboards, and right-hand member is provided with several sections.
In order to be able to increase radiating effect, reducing tail gas noise, described sideboard is arranged on the cross section of body, is provided with multiple
Passage；The center of described sideboard is heat-conducting plate, and the outer rim of heat-conducting plate is fixing with protection tube to be connected.
In order to be able to increase radiating effect, the outer surface of described exhaustor body is also equipped with fin.
As preferably, described heat-conducting plate and fin are to be all provided with on disc-shaped structure, and the card of heat-conducting plate and fin
There is heat radiation circular hole.
As preferably, described heat-conducting plate and fin all use welding manner to be connected with exhaustor body.
In order to prevent the backflow of scavenging solution in catching device, described section is to be arranged in chamber body the anchor ring tilted,
Anchor ring is 10-90 degree with the tube wall angle of body outlet side.
The beneficial effects of the utility model can be drawn by such scheme: owing at exhaustor, this most internal is provided with section,
Can effectively prevent the scavenging solution in catching device from the phenomenon of backflow occurring.Thus avoid making to start because of the backflow of scavenging solution
Machine occurs abnormal, has good protective effect to automobile engine.It is provided with heat-conducting plate in exhaustor simultaneously, and in aerofluxus
The fin of tube body outer wall welding, it is possible to effectively reduce temperature when tail gas is discharged, it is possible in effectively preventing catching device
Solution explosive evaporation, catching device is had good defencive function.Exhaustor body can effectively be had by protection tube
Good defencive function, its sideboard arranged at the inner chamber of exhaustor body, and the passage arranged at sideboard inner chamber, it is possible to
Effectively reduce produced noise when tail gas is discharged, there is preliminary silencing function.Motor vehicle exhaust emission of the present utility model is prevented
Backflow cooling exhaust pipe structure, wherein heat-conducting plate and fin are circular configuration, and the inner chamber of heat-conducting plate and fin is all provided with
Having circular hole, the inner chamber of protection tube is evenly distributed with louvre, and such setting can effectively improve dissipating of exhaustor body
Hot merit energy.
As can be seen here, this utility model compared with prior art has substantive distinguishing features and progress, its useful effect implemented
Fruit is also apparent from.
Accompanying drawing illustrates:
Fig. 1 is this utility model overall structure cross-sectional schematic；
