Abstract
A muffling board belongs to technical field of central air conditioners. The muffling board is of a multi-layer composite structure. A muffling layer is arranged between a muffling outer board and a muffling inner board, muffling holes are evenly arranged on the muffling inner board, and a muffling material is filled in the muffling layer. The muffling board has the advantages of being applicable to any occasion, good in muffling effect, long in service life and the like.
Description
Technical field
The utility model belongs to the central air-conditioning technical field, is specifically related to a kind of central air-conditioning airduct muffling device.
Background technology
At present, be used for the acoustical panel of central air-conditioning airduct, be generally the cotton formula acoustical panel of veneer noise reduction, the erasure effect of this kind structure is bad, and service life is short; Another is the microperforated panel muffler, and this muffler is subjected to be not suitable for installing the microperforated panel muffler in the airduct of the restriction of occasion, particularly central air-conditioning.
Summary of the invention
The purpose of this utility model provides a kind of acoustical panel, and to solve the cotton formula acoustical panel of prior art veneer noise reduction, erasure effect is bad, and service life is short; Another is the microperforated panel muffler, and this muffler is subjected to be not suitable for installing problems such as microperforated panel muffler in the airduct of the restriction of occasion, particularly central air-conditioning.
The utility model mainly is made up of the noise reduction outside plate, solving the technical scheme that its problem adopts is that this acoustical panel is multi-layer compound structure, between noise reduction outside plate and the noise reduction inner panel noise reduction layer is set, the noise reduction outside plate is imperforate plate, the noise reduction inner panel is porous plate, bloop evenly is set on the noise reduction inner panel, fills quieter material in the noise reduction layer.
Adopting good effect of the present utility model is to be applicable to any occasion, and erasure effect is good, advantages such as long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model B-B view;
1 noise reduction outside plate, 2 noise reduction layers, 3 noise reduction inner panels, 4 bloops among the figure.
The specific embodiment
Bloop is that circular configuration is example:
As shown in Figure 1: this acoustical panel is multi-layer compound structure, between noise reduction outside plate 1 and the noise reduction inner panel 3 noise reduction layer 2 is set, noise reduction outside plate 1 is imperforate plate, noise reduction inner panel 3 is porous plate, bloop 4 evenly is set on the noise reduction inner panel 3, bloop 4 is circular configuration, fills quieter material in the noise reduction layer 2, and quieter material is the noise reduction cotton.
