Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment
Shown in reference Fig. 1, the noise insulation device that the embodiment of the present invention provides, including: shell 10, opposite sides opening, wherein the first side opening 101 seals with the air outlet of rack and coordinates, and the second side opening 102 communicates with the external world; Multiple hush pipes 11 being arranged side by side, hush pipe 11 is placed in shell 10, and its length direction is all arranged along the direction of the first side opening 101 to the second side opening 102; Sound-proof material 12, is filled between hush pipe 11 and between hush pipe 11 and shell 10.
The noise insulation device that the embodiment of the present invention provides, the air outlet of the first side opening 101 and rack is tightly connected, specifically, the connection of the first side opening 101 and the air outlet of rack can by the mode such as adsorbing, screw be fixed, engages, the sealing of junction can be passed through to arrange sealing ring 13 in junction (as the first side opening 101 is peripheral) and realize, and the present embodiment does not limit. Preferably, above-mentioned first side opening 101 and the size of air outlet, mating shapes, easy for installation and can ensure that noise does not leak preferably.
The multiple hush pipe 11 of the present embodiment is arranged side by side and is placed in shell 10, and its length direction is all arranged along the direction of the first side opening 101 to the second side opening 102, Sound-proof material 12 is filled between hush pipe 11 and between hush pipe 11 and shell 10, effect due to Sound-proof material 12, vertical enclosure 10 outward direction is absent from noise, and the air outlet of rack along hush pipe 11 transmit time noise can weaken gradually, meeting design requirement until being reduced to, discharging from the second side opening 102. Wherein, the length of hush pipe 11, sectional area and quantity can be determined according to the noise content size of rack, and general uniform intervals lays.
Above-mentioned hush pipe 11 also known as the deafener (Muffler) of tubulose, is a kind of tubular device stoping sound transmission and allowing air-flow to pass through, is the important measures eliminating air power noise. Hush pipe is mounted in the device reducing noise on the gas channel of air powered equipment (equipment as bigger in air vent noises such as aerator, air compressor machine, boiler exhaust mouth, electromotor, water pumps) or in inlet and exhaust system. The kind of hush pipe is a lot, but studies carefully its noise elimination mechanism, they can be divided into type six kinds main again, i.e. resistive noise reduction, resistant noise-reducing, impedance complex formula noise reduction, microperforated panel noise reduction, aperture noise reduction and active noise reduction. Resistive noise reduction reduces noise mainly by sound-absorbing porous material; Resistant noise-reducing is filtered gradually eliminating the noise by the cell with pipe; Impedance complex formula noise reduction is combined according to certain mode by resistive structures and resistance structure, the above-mentioned noise reduction mode of compound use; Microperforated panel noise reduction is usually and utilizes microperforated panel soundabsorbing construction, selects the chamber that different punching rates is different with thickness of slab deep, it is possible to control the spectral performance of noise reduction so that it is obtain good erasure effect in the frequency range needed; Active noise reduction ultimate principle is in original sound field, and one equal in magnitude with original acoustic pressure, the sound wave of opposite in phase to utilize electronic equipment to produce again so that it is offsets with original sound field within the specific limits. Concrete structure and the noise reduction principle of hush pipe 11 are not limited by the present embodiment, have no effect on radiating effect as long as noise elimination can be realized or affect less.
Exemplarily, as in figure 2 it is shown, hush pipe 11 can be made up of following structure: tubing 111, alternatively, resistant to elevated temperatures plastic material or metal material is adopted to make; It is overlying on the silencing cotton 112 of tubing 111 inwall, silencing cotton is also referred to as acoustical cotton, being usually a kind of by single or web-like/flaky material of processing through kinds of processes of multiple different fiber, widely used is bi-component silencing cotton at present, and polyester acoustical cotton is one therein.
Preferably, above-mentioned noise insulation device may also include that magnetic absorption device, for the first side opening 101 is adsorbed on the air outlet of rack. Adopting suction type, existing rack can dock with above-mentioned noise insulation device without changing, highly versatile, and conveniently installs and dismounting.
Preferably, the air outlet of the first side opening 101 and rack seals and fits through sealing ring 13 and realize. Further, sealing ring 13 is internal arranges Magnet, and sealing ring 13 becomes ferromagnetism sealing ring, when docking with the air outlet of rack, realizes the encapsulation process of the fixing of noise insulation device and joint simultaneously.
The noise insulation device that the present embodiment provides, it is adaptable to be assemblied in the air outlet of rack, solves the problem that existing rack noise is excessive, does not affect the heat radiation of rack simultaneously, and realizes dust-proof process.
