Water absorption device of noise silencing ladle for automotive air exhaustion, noise silencing ladle and automobiles

Abstract

The invention discloses a water absorption device of a noise silencing ladle for automotive air exhaustion, a noise silencing ladle and automobiles, and relates to the technical field of water absorption device of the noise silencing ladle. The water absorption device comprises a shell, a window shutter, water absorption filler and a heater, wherein an accommodating chamber is arranged in the shell; the top of the accommodating chamber is opened and is used for communicating with the bottom of the noise silencing ladle; the window shutter is arranged on the side wall of the shell; the water absorption filler is arranged in the accommodating chamber; and the heater is arranged in the shell and is used for heating the water absorption filler. According to the water absorption device, accumulated water in the noise silencing ladle can be absorbed by using the water absorption filler, and the water absorption filler can be heated through the heater during driving, and the absorbed water is drained out; and through arrangement of sound absorbing cotton, noise can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust muffler packs, and more specifically relates to a water absorbing device for automobile exhaust muffler packs, a muffler pack and an automobile. Background technique [0002] After a vehicle with an exhaust system noise reduction package is idle for a certain period of time, water will accumulate in the noise reduction package, which is prone to corrosion problems. In areas with low temperature, when the vehicle is parked, the condensed water in the exhaust system flows into the muffler package along with the pipeline, and the condensed water contains acidic substances, which are corrosive to the inner surface of the muffler package. At present, drainage holes are usually drilled at the bottom of the muffler to solve the problems of water accumulation and corrosion. The existing problems are: the internal structure of the muffler is complex, the drainage effect is poor, and the residual...

Problems solved by technology

At present, drainage holes are usually drilled at the bottom of the muffler to solve the problems of water accumulation and corrosion. The existing problems are: the internal structure of the muffler is complex, the drainage effect is poor, and the residual acidic substances still have a corrosive effect on the shell of the muffler; The drain holes have noise problems under high-speed airflow when driving
