Sound absorption window

Technical Field

Background

Many places or workshops have high requirements on ventilation effects of the shutter doors and windows, such as a singing hall, a machining workshop, a chemical workshop, stone machining and the like, and in general, the workshop temperature can reach more than 40 degrees, and some of the workshops can reach 80 degrees, so that the shutter doors and windows cannot work normally in the environment, and heat dissipation becomes a primary problem. The existing heat dissipation modes are all natural ventilation, namely heat exchange is carried out between the louver and outdoor air, and although the heat can be effectively dissipated through the louver, a large amount of noise is also transmitted to the outdoor through the louver, so that noise pollution is caused. Therefore, the device which can prevent dust and noise and is breathable becomes the first choice of people.

In the prior patent application, the publication number is CN1584976A, which discloses a silencing laminated material and a shutter made of the same, wherein the silencing laminated material comprises a metal plate and centrifugal glass wool, and also discloses a silencing shutter blade made of the silencing laminated material by bending into a bridge shape, and the silencing shutter blade comprises a flat part and a bent part; however, the blade length must be shortened to change the air permeability, so that the noise preventing performance is not good. There is therefore a need for a sound absorbing window to eliminate noise and increase breathability that is not compatible.
