A Shuttle-Type Disc Muffler

Abstract

The present invention relates to a shuttle-type chip muffler, which is characterized in that the muffler comprises a rectangular shell, and several mufflers are arranged at equal intervals inside the shell, and the cross-section of each muffler along the airflow direction is Fusiform with pointed ends and wide middle. In the present invention, a series of narrow and long ventilation paths similar to Venturi tubes are manufactured by changing the traditional muffler with a rectangular cross-section into a shuttle-shaped muffler, so that without changing the flow area, The resistance loss of the air inlet / exhaust port of the muffler is greatly reduced; at the same time, the invention can obtain a noise reduction effect similar to that of the traditional muffler, and solves the problem that the noise reduction effect and the ventilation effect of the traditional sheet type muffler cannot be combined to a certain extent.

Description

technical field [0001] The invention relates to a sound-absorbing structure, in particular to a shuttle-type sheet-type muffler which takes into account both sound-absorbing performance and aerodynamic performance. Background technique [0002] A muffler is a device that allows airflow to pass through smoothly and can effectively reduce noise. In other words, a muffler is an airflow channel with a sound-absorbing lining or a special structure that can effectively reduce noise. It can be seen that, as a series of mufflers, it is necessary to provide two indicators of noise reduction performance and ventilation performance at the same time. Usually, ventilation performance, also called aerodynamic performance, is one of the important indicators for evaluating the performance of mufflers, and it is also a factor that should be fully considered in muffler design. The noise reduction performance of the traditional muffler is poorly compatible with the aerodynamic performance, th...

AI Technical Summary

Problems solved by technology

The noise reduction performance of the traditional muffler is poorly compatible with the aerodynamic performance, that is, if you want to obtain a large amount of noise reduction, you must lose more resistance to achieve it; if you want to obtain a smaller resistance loss, you must sacrifice greater sound dampening performance

And if a muffler with high noise reduction is installed in the ventilation system, due to poor aerodynamic performance and high resistance, the entire ventilation system cannot operate normally, then this muffler cannot be used.
