Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model is entered inside device in air-flow by air inlet by the first liner of setting and the second liner
When, the weakening of wind-force is carried out by wind deflector, air-flow is effectively reduced to bloop) shock, the generation of noise is reduced, by the
Centrifugally glass-wool, glass fabric and liner orifice plate in one liner make air-flow effectively reduce friction in flow process, lead to
Cross bloop) in orifice plate, glass fabric and centrifugally glass-wool in the second liner reduce air-flow propagation rate, orifice plate makes air
Enter the weakening for carrying out sound in the hole of multiple noise eliminations in the circulation process, is discharged, effectively reduces finally by exhaust outlet
The propagation of sound.
