Embodiment
As Fig. 1～shown in Figure 4, the utility model silencing means comprises the cover body 1 with lower concave space, and the Door of communication apparatus cabinet 2 of cover body 1 removably is installed by jockey, and the cavity with air inlet duct and exhaust passage 3 that is surrounded by cover body 1 and Door of communication apparatus cabinet 2.
Particularly, the dividing plate 4 that this cavity 3 is divided into air inlet duct and exhaust passage of the interior arrangement of cavity 3 that surrounds at cover body 1 and Door of communication apparatus cabinet 2, be respectively equipped with the first air inlet 6a and the first air outlet 6b of diagonal angle distribution each other on a pair of opposing sidewalls 12 of cover body 1, the first air inlet 6a is communicated with respectively with the second air inlet 7a that is located at Door of communication apparatus cabinet 2 and the second air outlet 7b by air inlet duct and exhaust passage with the first air outlet 6b.Be provided with suspension member 10 on Door of communication apparatus cabinet 2, be provided with the through hole 8 corresponding with suspension member 10 positions on cover body 1, cover body 1 can be articulated on Door of communication apparatus cabinet 2 by through hole 8 and suspension member 10; Arbitrary sidewall of cover body 1 is provided with a plurality of the first bolt hole 9a, also be provided with on Door of communication apparatus cabinet 2 and a plurality of the first bolt hole 9a positions corresponding a plurality of the second bolt hole 9b respectively, during installation, use is passed the first bolt hole 9a and is connected the bolt of bolt hole 9b cover body 1 is connected with Door of communication apparatus cabinet 2.
During concrete the use, above-mentioned suspension member 10 can be elected clothes-hook, screw or projection etc. as, and through hole 8 can be made as hardy hole, Eight characters hole or groove etc.As a kind of optimal way, through hole 8 on cover body 1 and the quantity of the suspension member 10 on Door of communication apparatus cabinet 2 are respectively 4, the first bolt hole 9a on arbitrary sidewall of cover body 1 and the quantity of the second bolt hole 9b on Door of communication apparatus cabinet 2 are respectively 2, correspondingly, the bolt quantity that passes the first bolt hole 9a and the second bolt hole 9b is 2.
The working mechanism of the utility model silencing means is: when rack was worked, under the rotarily driving of blower fan, air was sucked into from the air inlet 7a of Door of communication apparatus cabinet 2, discharged from air outlet 7b after cold cycling, realized radiating and cooling (as Fig. 2).after cover body 1 is installed on Door of communication apparatus cabinet 2, the cavity 3 that surrounds between itself and Door of communication apparatus cabinet 2 is divided into air inlet duct and exhaust passage by dividing plate 4, make the second air inlet 7a of Door of communication apparatus cabinet 2 and the second air outlet 7b through air inlet duct and exhaust passage are communicated with the first air inlet 6a and the first air outlet 6b of cover body 1 respectively thus, realize long ventilating path and advance independently respectively, the air-out circulation, be that air first enters cavity 3 from the first air inlet 6a, enter in rack from the second air inlet 7a through air inlet duct, being converted into hot blast after cold cycling discharges from the second air outlet 7b, finally discharge from the first air outlet 6b through the exhaust passage.Cover body 1 has formed a mazy noise elimination wind conduit with Door of communication apparatus cabinet 2, and the introducing of dividing plate 4 makes air inlet system and outlet system of air fully independent, and air inlet duct and exhaust passage have been elongated in mutually noninterfere simultaneously, the sound-deadening and noise-reducing successful.
Further, silencing means of the present utility model is mounted with dismountable acoustical cotton 5 in cavity 3, for example with gum, acoustical cotton 5 is sticked on inwall 11, sidewall 12 and the dividing plate 4 of cover body 1, and fix with securing member, acoustical cotton 5 comes off when preventing that gum effect lost efficacy.During rack work, sound wave is through contacting with silencing cotton 5, friction from the space of silencing cotton 5 self hole material and change into heat loss and dissipate, noise is obviously weakened, the sound wave that weakens enters in rack through air inlet duct, the second air inlet 6b, spread out of from the second air outlet 6a, the further noise reduction of silencing cotton 5 spreads out of from the first air outlet 6a in the exhaust passage.By increase acoustical cotton 5 in labyrinth type air duct, can play better the effect of sound-deadening and noise-reducing.
For the ease of the installation of engineering, the cover body 1 of the utility model silencing means adopts the lighter aluminium sheet material of weight to make.
In addition, the utility model also provides a kind of outdoor cabinet that comprises above-mentioned silencing means, and other structures are same as the prior art.
Silencing means of the present utility model is by at cover body 1 and the interior arrangement dividing plate 4 of 2 cavitys that surround 3 of Door of communication apparatus cabinet, cavity 3 is divided into air inlet duct and exhaust passage, elongated as far as possible into and out of the air channel in limited space, thereby form a kind of labyrinth type air duct, make into and out of the air port position transfer, can effectively abate the noise; By increasing acoustical cotton 5 at positions such as the inwall 11 of dividing plate 4, cover body 1 and sidewalls 12, make the sound-deadening and noise-reducing effect more obvious.In addition, cover body 1 has adopted the aluminium sheet material, and weight is lighter, is convenient to project installation, installs by articulating with the fixing mode of bolt between cover body 1 and Door of communication apparatus cabinet 2, and is convenient, firm, quick, save time and be convenient to and safeguard, improved the engineering competitiveness of whole set equipment.
Although above the utility model has been done detailed description; but the utility model is not limited to this; those skilled in the art can modify according to the interior perhaps principle of the utility model record; therefore, all various modifications of carrying out according to the interior perhaps principle of the utility model record all should be understood to fall into protection range of the present utility model.
