Abstract
The utility model relates to an outdoor integrated cabinet, in particular to a noise reduction structure of an outdoor integrated cabinet. The noise reduction structure comprises a middle whistle box, wherein two sides of the middle whistle box are respectively and vertically provided with a left whistle box and a right whistle box; hollow structures among the middle whistle box, the left whistle box and the right whistle box are communicated with each other to form an air flue; the bottom of the middle whistle box is provided with an air inlet; two ends of the left whistle box and the right whistle box are provided with air outlets; and the inner walls of the middle whistle box, the left whistle box and the right whistle box are pasted with noise reduction cottons. The air flue structure of the noise reduction structure plays the role of a muffler and does not influence heat emission; is concealed in installation, and does not influence aesthetics due to installation between the roof and the cabinet, thus enabling the user to use the noise reduction structure more conveniently.
Description
Technical field
The utility model relates to outdoor integrated cabinet, especially a kind of noise reducing structure of outdoor integrated cabinet.
Background technology
Outdoor integrated cabinet is the outdoor cabinet that designs for access network equipment specially, possesses good windproof, sand prevention, function such as rainproof, sun-proof and antitheft; Good environmental adaptability can lower outdoor access network equipment to greatest extent to environment requirement.Progressively maturation along with product, the client also is not only to consider on its some basic functions to the requirement of outdoor cabinet, but require producer in the design concept that satisfies more under the basic function situation " hommization " " automation ", come the daily operation and maintenance of convenient client.
During the routine work of integrated cabinet, when in-cabinet temperature reached certain value, blower fan can start automatically out of doors, because the space in the cabinet is excessive, so the power of fan that requires is also higher, though radiating effect is quite good, had also brought high noisy simultaneously.Particularly outdoor integrated cabinet all is installed in the user sub-district, if structural design is unreasonable, the high noisy of generation can influence resident's normal rest.So the structural design of outdoor integrated cabinet must be outside satisfying basic heat radiation requirement, the noise that is produced when reducing blower fan work as far as possible.
Summary of the invention
In order effectively to reduce the noise that produces when blower fan is worked, the utility model provides a kind of noise reducing structure of outdoor integrated cabinet.
The purpose of this utility model is achieved through the following technical solutions: a kind of noise reducing structure of outdoor integrated cabinet, has middle Sound Attenuator, be vertically installed with left Sound Attenuator and right Sound Attenuator respectively in the both sides of middle Sound Attenuator, the mutual breakthrough form of hollow structure becomes the air channel between middle Sound Attenuator, left Sound Attenuator and the right Sound Attenuator, bottom at middle Sound Attenuator is provided with air inlet, is provided with air outlet at the two ends of left Sound Attenuator and right Sound Attenuator.
In order to strengthen noise reduction, further: the inwall of Sound Attenuator, left Sound Attenuator and right Sound Attenuator is pasted with the noise reduction cotton in the middle of described.
Air channel structure of the present utility model has played the effect of muffler, does not influence the discharge of heat.And install hiddenly, and be contained between machine top and the rack and do not affect the appearance, make the convenient use of user.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. Sound Attenuator 2. left Sound Attenuator 3. right Sound Attenuator 4. air inlets 5. air outlets 6. noise reduction cottons in the middle of
Embodiment
The noise reducing structure of a kind of outdoor integrated cabinet as shown in Figure 1, has middle Sound Attenuator 1, be vertically installed with left Sound Attenuator 2 and right Sound Attenuator 3 respectively in the both sides of middle Sound Attenuator 1, the mutual breakthrough form of hollow structure becomes the air channel between middle Sound Attenuator 1, left Sound Attenuator 2 and the right Sound Attenuator 3, this air channel is arranged between dismountable cabinet top and the casing, the air channel uses the hot-dip galvanizing sheet steel of 1.0 millimeters thickness to make, and the inboard is pasted with the rough noise reduction cotton 6 of porous.Be provided with air inlet 4 in the bottom of middle Sound Attenuator 1, be provided with air outlet 5 at the two ends of left Sound Attenuator 2 and right Sound Attenuator 3.
Temperature-controlled fan enters the air channel to the high noisy of the heat in the cabinet and oneself generation by air inlet 4 together, at first with middle Sound Attenuator 1 in noise reduction cotton contact 6, sound wave with the hole of the cotton hole of noise reduction material in friction and change into heat loss and dissipate, noise is obviously weakened, the sound wave that weakens begins respectively to propagate as the left Sound Attenuator 2 of both sides and right Sound Attenuator 3, left Sound Attenuator 2 and right Sound Attenuator 3 porch sound waves take place again branch to.And continue to contact counteracting with noise reduction face on it, through twice break-in with the contacting of noise reduction face, sound wave obviously weakens, and is outwards propagated by air outlet 5 places of left Sound Attenuator 2 and right Sound Attenuator 3, subtracts the sound process and finishes.
Claims (2)
1. the noise reducing structure of an outdoor integrated cabinet, it is characterized in that: have middle Sound Attenuator (1), be vertically installed with left Sound Attenuator (2) and right Sound Attenuator (3) respectively in the both sides of middle Sound Attenuator (1), the mutual breakthrough form of hollow structure becomes the air channel between middle Sound Attenuator (1), left Sound Attenuator (2) and the right Sound Attenuator (3), be provided with air inlet (4) in the bottom of middle Sound Attenuator (1), be provided with air outlet (5) at the two ends of left Sound Attenuator (2) and right Sound Attenuator (3).
