A noise reduction cooling structure for an engine

Abstract

The invention discloses a silencing and cooling structure of an engine. The silencing and cooling structure of the engine comprises a silencing tube shell. The surface of the silencing tube shell communicates with a gas inlet tube and a gas outlet tube. The inner wall of the silencing tube shell is fixedly connected with a silencing plate. The surface of the silencing tube shell is fixedly connected with a cooling tube. The surface of the gas inlet tube is fixedly connected with a heat insulation ring. The surface of the heat insulation ring is fixedly connected with a connecting ring. The outer wall of the connecting ring is fixedly connected with an annular water tank. The surface of the annular water tank communicates with the two ends of the cooling tube. The surface of the cooling tube is provided with a micro water pump. The surface of the silencing tube shell communicates with a noise reduction contact tube. The surface of the noise reduction contact tube is fixedly connected with the surface of the cooling tube. According to the silencing and cooling structure of the engine, the annular water tank and the noise reduction contact tube can be used for limiting the flowing speed of gas in the silencing tube shell during device operation, so that noise generated by the flowing speed of the gas in the noise reduction contact tube is reduced, and better heat dissipation and sound insulation effects of a noise reduction device are achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an engine noise reduction cooling structure. Background technique [0002] The engine is the core component of the car. When the engine is working, external air enters the engine, and the piston of the engine compresses the air and oil vapor and ignites it through an electric spark, so that the combustion pushes the piston to rotate and do work, so that the output shaft of the engine keeps rotating. The exhaust gas produced by the combustion of air and oil and gas needs to be discharged to the outside through the exhaust pipe, but because the exhaust pipe will generate huge noise when exhausting, it is necessary to install a muffler to reduce the large amount of noise generated by the automobile exhaust pipe to an appropriate level To ensure that the car will not affect the normal life of the residents around the road during driving. [0003] When the existing engine noise re...
