Noise-eliminating and heating device of vehicle exhaust

Abstract

The invention discloses a noise-eliminating and heating device of vehicle exhaust, comprising a heat-exchanging machine core. The heat-exchanging machine core comprises an air inlet end and an air outlet end, wherein the air inlet end is connected with a vehicle exhaust pipe and provided with an exhaust smoke door, the air outlet end is provided with a noise-eliminating device in the heat-exchanging machine core, another noise-eliminating device is also arranged at the joint of the vehicle exhaust pipe and the heat-exchanging machine core which is internally provided with a coil heat exchanger pipe, the coil heat exchanger pipe comprises an influent pipe and an effluent pipe which both adopt separate metal hoses, and the effluent pipe is provided with an exhaust valve. The noise-eliminating and heating device of the vehicle exhaust is provided with the noise-eliminating device on the heat-exchanging machine core, supplies heat by the vehicle high-temperature exhaust, not only can satisfy the noise-eliminating effect, but also has the advantages of favorable high heating effect, simple structure, convenient operation and maintenance and convenient and dismountable whole structure without oil consumption or secondary pollution.

Description

technical field [0001] The invention relates to a heating device, in particular to an automobile exhaust noise-silencing heating heating device which utilizes the high-temperature exhaust gas of the automobile itself to heat the interior of the vehicle. Background technique [0002] With the development of the economy, automobiles have become a tool that people use daily. Due to the continuous increase of automobile fuel consumption and the aggravation of automobile emission problems, the problems of automobile fuel saving and environmental protection have become increasingly prominent. Facing the limited oil resources and the national energy strategy. The threats and challenges of automobile energy saving and environmental protection technology have become the research and development hotspots in the field of automobile technology. At present, the fuels of buses, large and medium-sized passenger cars are generally diesel and natural gas, and a large amount of high-temperatur...

[0002] With the development of the economy, automobiles have become a tool that people use daily. Due to the continuous increase of automobile fuel consumption and the aggravation of automobile emission problems, the problems of automobile fuel saving and environmental protection have become increasingly prominent. Facing the limited oil resources and the national energy strategy. The threats and challenges of automobile energy saving and environmental protection technology have become the research and development hotspots in the field of automobile technology. At present, the fuels of buses, large and medium-sized passenger cars are generally diesel and natural gas, and a large amount of high-temperature exhaust gas is discharged into the atmosphere, which is not conducive to environmental protection. , and wasting a lot of precious heat energy in vain
