Motor-fan is encapsulated in the housing, this housing is topped motor, topped fan on the other hand on the one hand, with the pipeline guiding air that fan blowed, this can reduce the pressure wave of bump shell wall, therefore reduces the sound wave of propagating by these walls of shell simultaneously.And, by for example motor-fan part and shell being isolated by the vibrationproof fixture of ethylene-propylene-diene monomers (EPDM) trimer manufacturing, thereby this has eliminated all firm bridge joints that motor-fan part are connected in shell, and makes decay significantly propagate into the noise of the outside of described shell.
In addition, rely on the fixture between its fixing ceiling to absorb of the residual vibration of shell bump shell by being arranged on shell and shell, and reduced the noise that so can produce its fixing building.Therefore the effect of isolation motor-fan part has been augmented in the effect of these fixtures.Because their base plate that contact with ceiling is the bell of loudspeaker, so obtained the effective especially deadening of fixture.This is bell to have formed the diaphragm that relies on its strain to absorb a deflection of the vibration of propagating from shell.
Select as one, the link position place between housing and shell inserts a vibrationproof convex surface formula piston ring (bellows), so that any residual vibration of this housing that for example may be transmitted by the air-flow that leaves this housing can not propagate into shell.
As a selection, this housing is made by a kind of accrete molded thermoplastic of sound insulation that is filled with.
Select as one, shell is fixed in ceiling by all screws of the hollow pin that is positioned at the sound insulation fixture.
In addition, as a selection, fixture is made by ethylene-propylene-diene monomers (EPDM) trimer.Because its good absorbing performance, so for example this trimeric material can be used for this application scenario.Yet also can use with the neoprene latex is the copolymer of base.
Equally, shell is preferably made by being filled with the accrete molded thermoplastic of sound insulation.
And at least one vertical wall and roof in all vertical walls of shell are crooked.When by pressure wave impinges, all planomurals of a chamber play the effect of picture barrier film usually.This pressure wave converts sound wave to then.In this case, the curved shape of wall is restricted the barrier film phenomenon, therefore limits the outside that sound wave propagates into shell.
According to a preferred embodiment of the present invention, on all upright arms of shell ribs is arranged.In this case, rib is understood that to mean a local additional amount of wall thickness, and it is straight that rib is preferably.As in having the situation of curved wall, ribbing helps to improve the deadening of wall to wall.This is because rib has strengthened wall, therefore when by pressure wave impinges and the motion of barrier film relatively limited its motion.
Can make up many ventilation unit sound insulation parts as previously discussed fully.
