Abstract
The invention discloses a special vehicle tail exhaust pipe with a rapid cooling function. The special vehicle tail exhaust pipe with the rapid cooling function comprises an exhaust steel pipe body and is characterized in that the exhaust steel pipe body comprises three steel pipe bodies comprising the intake steel pipe body, the buffering pipe body and the exhaust steel pipe body which are fixedly connected in sequence, the intake steel pipe body is communicated with the buffering pipe body, and the buffering pipe body is communicated with the exhaust steel pipe body. According to the special vehicle tail exhaust pipe with the rapid cooling function, because the communicating buffering pipe body is additionally arranged in the middle of the tail exhaust pipe, exhaust is more rapid, cooling is effective, and cold air and hot gas which are inside and outside the tail exhaust pipe can be exchanged; besides, when the special vehicle tail exhaust pipe is used, high-temperature gas passing through the inner portion of the pipe can be rapidly cooled.
Description
Technical field
The present invention relates to a kind of automobile specified can the tailpipe of fast cooling, belongs to vehicle exhaust fast cooling device field.
Background technique
growing along with automotive industry, also more and more higher to the performance requirement of automobile exhaust pipe tubing used, the existing tubing being used as automobile exhaust pipe mostly is common stainless steel pipe, heat dispersion is not strong, outlet pipe inwall is subject to deteriorate under the effect of long term high temperature pressurized gas, causes shorten working life.Such as Chinese patent CN 203809879 U discloses the effective high-cooling property seamless steel pipe of a kind of automobile exhaust, comprise seamless steel pipe body (1), it is characterized in that: seamless steel pipe body (1) inwall circumferentially uniform intervals be welded with the heat absorption fins slip (1-1) that some parallel to an axiss along seamless steel pipe body (1) extend, seamless steel pipe body (1) outer wall circumferentially uniform intervals be welded with some the axially extended radiating fin slips (1-2) along seamless steel pipe body (1).Its advantage is: this automobile exhaust effective high-cooling property seamless steel pipe has good heat dispersion compared with existing like product, fast cooling can be carried out to the high temperature and high pressure gas passed through in pipe when using as automobile exhaust pipe, thus reduce intraductal atmospheric pressure and alleviate the erodibility of gas to inner tube wall, reach the object extending outlet pipe working life.Its shortcoming is that the number by increasing fin reaches the effect improving heat dispersion, and therefore its cost of using costly, and the effect depending merely on fin is dispelled the heat, and heat dissipation rate is still and has much room for improvement.
Summary of the invention
The object of this invention is to provide a kind of automobile specified can the tailpipe of fast cooling, obviously can be exchanged by inside and outside cold and hot gas, can to the high temperature and high pressure gas that pipe in pass through carry out fast cooling when automobile exhaust pipe uses simultaneously.
The technical solution used in the present invention is: a kind of automobile specified can the tailpipe of fast cooling, comprise exhaust steel pipe main body, its innovative point is: described exhaust steel pipe body comprises three sections of steel pipes, be respectively air inlet steel pipe, separator tube and steel pipe of giving vent to anger, this air inlet steel pipe, separator tube and steel pipe of giving vent to anger are fixedly connected sequentially, and air inlet steel pipe and separator tube are interconnected, separator tube and steel pipe of giving vent to anger are interconnected.
Further, described separator tube comprises the identical tubule of several diameters, and the diameter of this tubule is all less than the diameter of air inlet steel pipe and steel pipe of giving vent to anger; Several tubules described be arranged in parallel up and down, and are fixedly communicated in air inlet steel pipe respectively and give vent to anger between steel pipe.
Further, described tubule is evenly provided with several cellular apertures, the density of aperture arrangement is 3 ~ 5/cm
3.
Further, the diameter of steel pipe and air inlet steel pipe of giving vent to anger described in is identical or different.
Beneficial effect of the present invention is as follows:
(1) automobile specified of the present invention can the tailpipe of fast cooling, exhaust steel pipe body comprises three sections of steel pipes, be respectively air inlet steel pipe, separator tube and steel pipe of giving vent to anger, this air inlet steel pipe, separator tube and steel pipe of giving vent to anger are fixedly connected sequentially, and air inlet steel pipe and separator tube are interconnected, separator tube and steel pipe of giving vent to anger are interconnected, and increase the separator tube be communicated with in the middle of tailpipe, exhaust is more quick, effective temperature-reducing.
(2) automobile specified of the present invention can the tailpipe of fast cooling, and separator tube comprises the identical tubule of several diameters, and the diameter of this tubule is all less than the diameter of air inlet steel pipe and steel pipe of giving vent to anger; Several tubules be arranged in parallel up and down, and are fixedly communicated in air inlet steel pipe respectively and give vent to anger between steel pipe, can obviously be exchanged by inside and outside cold and hot gas, can carry out fast cooling when automobile exhaust pipe uses simultaneously to the high temperature and high pressure gas passed through in pipe.
(3) automobile specified of the present invention can the tailpipe of fast cooling, and tubule is evenly provided with several cellular apertures, the density of aperture arrangement is 3 ~ 5/cm
3, reduce intraductal atmospheric pressure, extend outlet pipe working life.
