Upper surface is connected, and the endoporus of the corresponding noise reducing plate 30 of the fan assembly 50 is set.The noise reducing plate 30 is generally metal material
Material or plastics are made, for example, the materials such as aluminium, stainless steel or vinyon can be used to be made, here, the noise reducing plate 30
It can play a part of strengthening shell.The shape of noise reducing plate 30 can have a lot, can be configured according to the shape of heat exchanger 20 with
With being that heat exchanger 20 preferably coordinates.Some perforation 31 are offered on noise reducing plate 30, when sound wave hits the noise reducing plate 30, are made
Obtain noise reducing plate 30 and produce resonance, substantial amounts of acoustic energy is absorbed under violent vibration, to realize the purpose of noise reduction sound-absorbing.
Perforation 31 can by punch forming, perforate 31 shape can have it is a variety of, for example, it may be circular hole, square hole, rib
Shape hole, the combination of tri-angle-holed, coniform hole any one or its.The attraction effect of noise reducing plate 30 also with perforation 31 size and
Percent opening is relevant, can be configured according to the actual requirements.Preferably, the perforation 31 is circular hole, its aperture be 1mm~
5mm, percent opening are 30%~60%.
In technical solutions of the utility model, by the way that the noise reducing plate 30 is located in into the heat exchanger 20 and the top plate
Some perforation 31 are offered between 11, and on the noise reducing plate 30, according to resonance sound-absorbing principle, when the fan assembly 50 works
Caused sound wave, and the fan assembly 50 work caused by air-flow hit sound wave caused by the heat exchanger 20, hit
The noise reducing plate 30, and resonance is produced, so as to sound energy consumption, to reach the purpose of noise reduction sound-absorbing.Meanwhile the noise reducing plate 30 is also
It can play a part of strengthening shell.
In order to further improve noise reduction sound-absorbing effect, the upper surface of the noise reducing plate 30 can be provided with sound-absorbing material layer
40, the sound-absorbing material layer 40 is made up of porous acoutic fibre board material or sound-absorbing foam material, such as can be sound-absorbing sea
Silk floss, rock wool, mineral wool or opening polyurethane foam etc..There are the hole of a large amount of small connections, sound inside above-mentioned sound-absorbing material
Ripple can go deep into material internal along these holes, and rubbing action occurs with material is converted into heat energy by acoustic energy.Pass through sound absorber
Noise reduction sound absorption twice, first sound wave and noise reducing plate occur in transmitting procedure for the cooperation of the bed of material 40 and noise reducing plate 30, noise
Resonance acoustical absorption effect is produced between 30, can effectively reduce low frequency noise, is occurred when then sound wave passes through sound-absorbing material layer 40 more
Hole sound absorption, high frequency noise can be effectively reduced, so as to greatly reduce the noise of ceiling machine, it is possible to increase the use of user
Comfortableness.
