Description
Technical field
The utility model relates to a kind of Heating,Ventilating and Air Conditioning components, more specifically, it relates to which a kind of divulge information for Heating,Ventilating and Air Conditioning
The silencer of system.
Background technique
The research of Heating,Ventilating and Air Conditioning ventilating system noise control is more than and considers to reduce noise, while to be created safe, easypro
Suitable acoustic environment, the sound-absorbing material using health, safety is to obtain a kind of indispensable measure of ideal acoustic environment institute, wide at present
The general sound-absorbing material used is mostly mineral fibres material, is mainly characterized by that at low cost, acoustic absorptivity is high, production is simple,
With social development, mineral fibres sound-absorbing material be Heating,Ventilating and Air Conditioning, ventilating system green safe aspect a big hidden danger,
In the reason is that mineral fibres sound-absorbing material easily forms harmful floating dust and pellet, certain damage is caused to human body
Evil is unfavorable for the permanent development of society.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind to be used for Heating,Ventilating and Air Conditioning ventage
The silencer of system.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of for Heating,Ventilating and Air Conditioning ventilating system
Silencer, including inlet section, thermal-arrest portion and noise elimination part, the noise elimination part include level-one noise elimination part and second level noise elimination part, and described one
Grade noise elimination part is close to the setting of thermal-arrest portion, and foaming noise reduction centrum is intensively provided on the level-one noise elimination part inner wall, and the foaming disappears
It is coated with high temperature resistant on sound centrum and reflects glue-line, the processing of V-type line, the second level noise reduction are done in the surface of the high temperature resistant reflection glue-line
Portion is coated on outside level-one noise elimination part, and the second level noise elimination part is honeycomb framework, is filled with silencing cotton in the honeycomb framework.
Preferably, being equipped with conical hollow supporting element between the level-one noise elimination part and second level noise elimination part.
Preferably, filled with the noise reduction metal plate folded inside the conical hollow supporting element.
The utility model is compared compared with the prior art to be had the advantage that the utility model has the advantage of features simple structure,
Noise reduction component in level-one noise elimination part and second level noise elimination part can easy replacement, and had both good performance muffler and heat preservation
Performance.

Specific embodiment
The silencer embodiment of the utility model Heating,Ventilating and Air Conditioning ventilating system is described further with reference to the accompanying drawing.
A kind of silencer for Heating,Ventilating and Air Conditioning ventilating system, including inlet section 1, thermal-arrest portion 2 and noise elimination part, noise elimination part packet
Level-one noise elimination part 3 and second level noise elimination part 4 are included, level-one noise elimination part 3 is close to thermal-arrest portion 2 and is arranged, intensively sets on 3 inner wall of level-one noise elimination part
It is equipped with foaming noise reduction centrum 31, high temperature resistant is coated on noise reduction centrum 31 of foaming and reflects glue-line, high temperature resistant reflects the surface of glue-line
The processing of V-type line is done, second level noise elimination part 4 is coated on outside level-one noise elimination part 3, and second level noise elimination part 4 is honeycomb framework 41, honeycomb frame
Silencing cotton is filled in body 41.The utility model has the advantage of features simple structure, in level-one noise elimination part 3 and second level noise elimination part 4
Noise reduction component can easy replacement, and had both good performance muffler and thermal insulation property.
Conical hollow supporting element 42 is equipped between level-one noise elimination part 3 and second level noise elimination part 4.Conical hollow supporting element 42 can
Enough that good supporting role is played between level-one noise elimination part 3 and second level noise elimination part 4, there are also disappear hollow pyramidal structure well
Remove the effect of sound wave.
Filled with the noise reduction metal plate folded inside conical hollow supporting element 42.Noise reduction metal plate plays reinforcement and supplement
The effect of noise reduction.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model, should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
