Cooling device with finned muffler

Abstract

The invention discloses a silencer heat radiating device with fins. The silencer heat radiating device with fins comprises a silencer barrel body, wherein the silencer barrel body is a casing of a resistive silencer in the prior art, a sound-absorbent material of a silencer is arranged at the inner wall position close to the side wall of the silencer barrel body, the side wall of the silencer barrel body is provided with at least one cooling fin chute, and the cooling fin chute is composed of a first groove cavity and a second groove cavity. The silencer heat radiating device with fins further comprises cooling fins identical to the cooling fin chutes in number and a circular-ring-shaped cooling fin end cover matched with the side wall of the silencer barrel body. The cooling fins are installed in the side wall of the silencer through the chutes, enough stable contact between the cooling fins and the side wall of the silencer is ensured through the chutes, the fins of the cooling fins extend out of the chutes, the whole heat radiating area is increased, accordingly heat absorbed by the resistive sound-absorbent material arranged on the inner wall of the silencer during running is led out, and the temperature stabilizing and sound absorption effects of the resistive material are reduced.

Description

technical field [0001] The invention relates to a cooling device for a muffler with fins. Background technique [0002] At present, there is a kind of resistive muffler. The resistive muffler material is arranged close to the inner wall of the muffler. After the motor vehicle has been driving for a long time, the heat brought by the hot air flow of the exhaust gas and the sound wave energy absorbed by the resistive muffler material are transformed into inner muffler. It may cause the temperature of the resistive material to increase, resulting in a decrease in the sound attenuation performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cooling device for a muffler with fins, which can effectively lead out the heat absorbed in the resistive sound-absorbing material provided on the inner wall of the muffler during driving, thereby reducing the resistance The material temperature stabilizes the sound-absorb...

After the motor vehicle has been driving for a long time, the heat brought by the hot air flow of the exhaust gas and the sound wave energy absorbed by the resistive muffler material are transformed into inner muffler. It may cause the temperature of the resistive material to rise, resulting in a decrease in the sound attenuation performance
