Abstract
The utility model discloses an aluminum alloy noise-reducing shutter and relates to the technical field of shutters. The aluminum alloy noise-reducing shutter comprises a window frame (1) and a shutter blade (2), wherein the shutter blade is fixed on the window frame (1). The aluminum alloy noise-reducing shutter is characterized in that the shutter blade (2) comprises an inner blade (2a), an outer blade (2b) and a noise-reducing material (3); the inner blade (2a) and the outer bade (2b) are fixed together and form a cavity; and the cavity is filled with the noise-reducing material (3). The aluminum alloy noise-reducing shutter has novel, reasonable and practical structural design, is made of aluminum alloy material, and is convenient for manufacture and flexible for combination and installation; and the surface is coated with fluorocarbon resin, so that the aluminum alloy noise-reducing shutter has favorable wear resistance and cannot fade after used for over 15 years. When an air current flows through the aluminum alloy noise-reducing shutter, the aluminum alloy noise-reducing shutter has low resistance, not only can reduce noise, but also can absorb sound, completely reflect and absorb the medium and low frequency noise, and meet the lower pressure drop requirement and effective noise prevention requirement when the air smoothly flows.
Description
Technical field
The utility model relates to the shutter technical field, particularly the aluminium alloys sound-deadening louver.
Background technology
Building for commercial use and industrial premises all need the air of big flow to be used for ventilation and air conditioning system, in many ventilation systems, equipment sends strong noise when producing air-flow, the problem that designer and engineer face is, should allow the smooth and easy circulation of air, prevent noise transmission simultaneously again to greatest extent.
Summary of the invention
At the problem of above-mentioned practical application, the purpose of this utility model is: a kind of aluminium alloys sound-deadening louver is provided, and it can either allow the smooth and easy circulation of air, plays sunshade, rainproof, draught effect, can prevent noise transmission to greatest extent again.
The technical solution adopted in the utility model is: a kind of aluminium alloys sound-deadening louver, comprise window frame and louvre blade, described louvre blade is fixed on the window frame, it is characterized in that, described louvre blade comprises intra vane, outer leafs and quieter material, described intra vane and outer leafs are fixed together, and form cavity, filling quieter material among the described cavity.
Described aluminium alloys sound-deadening louver is characterized in that, has small through hole on the described intra vane.
Described aluminium alloys sound-deadening louver is characterized in that, described outer leafs is or/and intra vane, and external surface is a streamiline surface.
Described aluminium alloys sound-deadening louver is characterized in that, the intra vane of described louvre blade and outer leafs adopt the aluminium alloy plate material to make.
Described aluminium alloys sound-deadening louver is characterized in that, described louvre surface spraying fluorocarbon resin or powdex.
Described aluminium alloys sound-deadening louver is characterized in that, described quieter material is fire prevention noise reduction cotton.
The utility model aluminium alloys sound-deadening louver, project organization novelty, reasonable, practical adopts aluminum alloy materials to make, and easy to make, aggregate erection is flexible, surface spraying fluorocarbon resin, good weatherability can be used more than 15 years colour-fast.The utility model air communication is out-of-date, and resistance is low, but can noise reduction also sound-absorbing, can reflect, absorb the low and medium frequency noise fully, lower pressure drop requires and effectively noise control requirement in the time of satisfying the smooth and easy circulation of air.
Below in conjunction with accompanying drawing, the utility model is further described, the following stated only is as the concrete example of implementing of the utility model, and is not the restriction that the utility model is done.
Description of drawings
Accompanying drawing is the utility model structural representation;
In the accompanying drawing: the 1-window frame; The 2-louvre blade; The 2a-intra vane; The 2b-outer leafs; The 2c-through hole; The 3-quieter material.
The specific embodiment
Shown in accompanying drawing, the utility model aluminium alloys sound-deadening louver comprises aluminium alloys window frame 1 and is fixedly mounted on louvre blade 2 on the aluminium alloys window frame 1, dress quieter materials 3 in the louvre blade 2.2 of each louvre blades of shutter leave ventilation gap, and aperture area is through well-designed, to reach maximum air mass flow and best acoustic characteristics.Present embodiment louvre blade 2 adopts 1.5 millimeters aluminium alloy plates to make, it comprises intra vane 2a and the outer leafs 2b that is fixed together, wherein intra vane 2a has through hole 2c punching aluminium alloy plate for dashing, intra vane 2a and outer leafs 2b form cavity, needs according to different occasions, filling quieter material 3 in cavity, as fire prevention noise reduction cotton, and egg drags shape noise reduction cotton etc.Intra vane 2a is provided with a lot of small through hole 2c, makes shutter can produce erasure effect preferably.Present embodiment aluminium closes noise reduction gold shutter surface spraying fluorocarbon resin, also can the dusty spray resin.
Except that the above embodiment, the utility model can also have other embodiments, this not superfluous one by one stating.Every employing is equal to the technical scheme of replacement or equivalent transformation formation, all belongs to the protection domain of the utility model requirement.
