Heat radiating noise reduction exhaust pipe

Abstract

The invention discloses a heat radiating noise reduction exhaust pipe. One end of a connecting portion of the exhaust pipe can be inserted into an air inlet pipe through an opening on one end of the air inlet pipe, the end being far away from an annular bending portion. A connecting position is in an annular clamping groove. An annular lining member structure is abutted against the inner wall of the annular clamping groove. A silencer is formed by a throttle pipe and a sound absorption device. The throttle pipe is connected with the sound absorption device. A turning position on the middle part of the sound absorption device is a noise eliminating portion. The sound absorption device is internally provided with an arc surface. The middle position of two adjacent arc surfaces on the internal upper part of the sound absorption device is provided with noise reduction cotton. The middle position of two adjacent arc surfaces on the internal lower part of the sound absorption device is provided with a radiator. An annular ring of the radiator is provided with radiating holes. The exhaust pipe prevents operation conditions of an engine from being influenced by different return pressure. The silencer is used to absorb and eliminate noise, and can improve sound eliminating effect of the device. The arc surface is added, so as to increase contact area of the arc surface with noise, to perform offset processing. The radiator improves heat radiation effect.

Description

technical field [0001] The invention belongs to the technical field of exhaust pipe equipment, and in particular relates to a heat-dissipating sound-absorbing exhaust pipe. Background technique [0002] The exhaust pipe is a very common exhaust component on the car. Its air inlet is connected with the gas exhausted from the engine and discharged from the outlet of the exhaust pipe. Existing automobile exhaust pipes usually include a left exhaust pipe and a right exhaust pipe, both of which are independent and usually each have four air inlets for respectively receiving gases discharged from the engine. The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The air pressure imbalance caused by the back pressure will in turn affect the exhaust condition and power performance o...

Problems solved by technology

The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The back pressure causes the air pressure to be unbalanced, which will in turn affect the exhaust condition and power performance of the engine, and even affect the running performance of the entire car.
