Abstract

The invention relates to a muffler and a maintenance method thereof. The muffler includes: a hollow shell, which is connected to the noise generating part; and a sound absorbing device, which is arranged inside the shell and extended toward the length direction of the shell, and the sound absorbing device includes a plurality of sound-absorbing units, and the plurality of sound-absorbing units are connected to each other toward the length direction of the housing.

Description

technical field [0001] The invention relates to a muffler and a maintenance method thereof. Background technique [0002] HVAC (Heating, Ventilation, Air Conditioning, air conditioning system) pipes are suitable for fluid delivery for heating, ventilation and cooling. The fluid is transported through the pipeline, and the fluid can be introduced into a specific space or exported from a corresponding space. [0003] The pipeline is provided with a blower for fluid delivery, and the noise generated from the blower will be transmitted through the fluid in the pipeline. Therefore, various noise reduction tools can be provided on the pipeline. Like pipes, the crackle of a diesel engine as its engine fires is carried through the fluid in the exhaust pipe. [0004] figure 1 Exhaust pipe noise is illustrated for a normal engine. refer to figure 1 , the exhaust pipe noise is mainly generated in the low frequency region compared to the high frequency region. [0005] The muffle...
