The exhaust pipe structure has small influences on a whole exhaust system of the automobile, heat transfer efficiency is high and the tail gas utilization rate is high.
Description
Technical field
The present invention relates to automobile manufacturing field, especially relate to a kind of exhaust pipe structure reclaiming automobile exhaust heat.
Background technique
After gas or liquid fuel mix with air by internal-combustion engine, in internal-combustion engine cavity, there is chemical reaction produce power and heat, after partial heat is converted to power, can directly be discharged in air by the outlet pipe of vehicle exhaust, tail gas heat quantity be wherein often very high.And along with automotive exhaust catalysis technology and turbine increase the continuous progress of technology, the tail gas heat quantity of discharging in car body can be more and more higher.The discharge of vehicle exhaust own will cause very large atmospheric pollution to air, and the heat of tail gas also can increase the temperature of air simultaneously, reduces the moisture index of air, the dust storm causing air to continue and drying.
In prior art, some technological schemes provide the technological means of the recovering device of automobile exhaust heat, but, there is the problems such as reuse efficiency is not high, heat transfer efficiency is not high.And the recovery of some technological schemes to heat just starts in the part of motor, add the assembly of vehicle structure undoubtedly, have influence on the performance of vent systems component function below, and reclaim the heat at motor place, collecting efficiency is low, utilization ratio is not high.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of exhaust pipe structure reclaiming automobile exhaust heat.
Object of the present invention will be achieved by the following technical programs: a kind of exhaust pipe structure reclaiming automobile exhaust heat, comprise catalyzer cylinder, described catalyzer cylinder inlet end is connected with intake manifold, described catalyzer cylinder outlet side is connected with downtake pipe, described downtake pipe is connected with tail gas recycle cylinder, described tail gas returns cylinder and comprises second exhaust pipe and flow duct, described flow duct is arranged in the inner chamber of described tail gas recycle cylinder, described flow duct is divided into double-layer sleeve structure, be respectively exhaust gas flow pipe and cold water flow pipe, described cold water flow pipe is connected with vehicle-mounted water tank.
Preferably, above-mentioned a kind of exhaust pipe structure reclaiming automobile exhaust heat: described flow duct is multiple tracks warp architecture.
Preferably, above-mentioned a kind of exhaust pipe structure reclaiming automobile exhaust heat: described tail gas recycle cylinder is positioned at the enclosure interior of car.
Preferably, above-mentioned a kind of exhaust pipe structure reclaiming automobile exhaust heat: described second exhaust pipe stretches out the outside of car.
