Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
In description of the present utility model, it is to be understood that term " on ", " under ", " " center ", " interior ", " outer ",
The orientation or position relationship of the instructions such as " top ", " bottom " are based on orientation shown in the drawings or position relationship, are for only for ease of and retouch
State the utility model and simplify and describe, rather than instruction or imply signified device or element must have specific orientation, with
Specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
As Figure 1-Figure 4, the utility model provides a kind of spindle cylinder staggered array type silencer, including fixed frame
1 and multiple sound absorbers 2, arranged into staggered array type between the sound absorber 2, the both ends of sound absorber 2 are fixedly installed on described
On fixed frame 1, the sound absorber 2 is arranged in parallel with air current flow direction, and the sound absorber 2 is spindle cylinder.So, take
Spindle cylinder is staggered, the silencing apparatus of cylinder and airflow direction parallel arrangement, sound deadening capacity and sky that can be as needed
Atmidometer calculates the volume for determining spindle cylinder and staggered arrangement, is ensuring to reach outside design noise reduction, is not changing
Silencer air channel gas flowfield and increase air channel flow area, the corresponding air through-flow pressure loss is smaller, energy consumption is lower；And
And as the spindle cylinder of sound absorption main body mould standard, mass can be used to manufacture, it can be ensured that the acoustic mass of sound absorber 2,
Structure and outward appearance.This have the advantage that in terms of existing technologies：Sound deadening capacity is big, the pressure loss is small, reproduced air-flow noise is low,
The comprehensive advantages such as in light weight and service life length.
Spindle cylinder staggered array type silencer of the present utility model, as Figure 1-Figure 4, in previously described technical side
It can also be on the basis of case：
The sound absorber 2 includes shell and sound absorption filler, and the shell is spindle cylinder, and the sound absorption filler is filled with
