Abstract

The invention discloses an automobile turbocharger air pressing pipe muffler. The automobile turbocharger air pressing pipe muffler includes an air pressing pipe body, a first muffling tube, a secondmuffling tube and a third muffling tube are welded to the air pressing pipe in a thermoplastic mode, and the good noise reduction effect on broadband noise of a certain rage can be achieved; a secondconnection port is threadedly connected with an air outlet to facilitate mounting on the air pressing ends of various types of compressors; according to the structure, the pipe diameter is rationallydesigned, and the flow field amount requirement of an air inlet system is unaffected; according to the structure, PP, PE, and other materials can be adopted, and manufacturing and assembly are simple;a first sealing rib, a second sealing rib, and a third sealing rib sleeve on an air inlet port, the first sealing rib, the second sealing rib, and the third sealing rib sleeve on an air outlet, according to the structure, a sealing structure is fully considered, the safe and reliable effects are achieved, and the structure is low in cost and good for marketization.

Description

technical field [0001] The invention belongs to the technical field of compressed air pipe muffler equipment, and in particular relates to a compressed air pipe muffler for an automobile turbocharger. Background technique [0002] The compressor side noise of automobile turbocharger has become the main noise source of indoor noise, and the noise mainly comes from the noise radiation inside the compressor side pipe. The invention can effectively suppress the noise on the compressed air side of the turbocharger. [0003] The muffler of the turbocharger is mainly used to solve the noise caused by the imbalance of the turbocharger rotor, such as CN201720495107.7, CN201620616579.9, CN201520345009.6, CN201320340651.6 and CN201520344857.5. Among them, CN201720495107.7 is a kind of elbow muffler with small holes in the inner tube, which is large in volume and is not conducive to the arrangement and installation in the engine compartment; CN201620616579.9 proposes a muffler with mul...
