Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
Main inventive concept of the present utility model is: in the door body framework of existing rack, the sound-absorbing section bar is set, the noise that utilizes the sound-absorbing section bar to stop the rack fan to rotate to produce or air channel produce noise outwards propagate; Reduce the rack overall noise.
Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is cabinet door structure schematic diagram in the present embodiment; Fig. 2 is cabinet door assembling schematic diagram in the present embodiment; Described cabinet door comprises a body framework 1 and sound-absorbing section bar 2; Described sound-absorbing section bar 2 is arranged at the inboard of described door body framework 1, and described door body framework 1 forms the air channel, and the hot blast that produces in the rack enters described cabinet door by the air inlet in described air channel, outwards propagates from described air outlet.When the noise of cabinet fan and air channel generation is outwards propagated from described cabinet door with air-flow, sound-absorbing section bar 2 in the described door body framework 1 can adsorb the noise sound wave, reduce the noise of outwards propagating, thereby reduce the whole noise that produces of rack, improve the overall performance of rack.
Further, described cabinet door can also comprise a backplate 3, and described backplate 3 is arranged at the air inlet end of described door body framework 1, and described backplate 3 is for the protection of the interior of equipment cabinet device; Further, on described backplate 3, can arrange and make things convenient for the ventilation hole that hot blast passes through in the rack, can make things convenient for the heat and the noise sound wave that produce in the rack to enter in the described door body framework 1 by described ventilation hole.
In the utility model one embodiment, as shown in Figure 3, described sound-absorbing section bar is extended in the middle of the air channel by both sides, and the sound ripple is contacted better with described sound-absorbing section bar 21.
Further, the sound-absorbing section bar 21 of both sides and the inlet and outlet Formation cross-section in air channel are trapezoidal shape, and wherein, described air outlet one end is less than air inlet one end; When the noise sound wave that described rack produces entered the air channel by air inlet, because the air channel narrows down, the noise sound wave contacted with sound-absorbing section bar 21 on the hypotenuse easily, thereby reached the purpose of absorption noise sound wave.
Further, in described air channel, baffle plate 15 can also be set, described baffle plate 15 is divided into the right and left with described door body framework 1, and is provided with sound-absorbing section bar 22 at the windward side of described baffle plate 15, two air channels about described baffle plate 15 and described sound-absorbing section bar 22 are divided into the air channel; Run into the sound-absorbing section bar on the middle baffle plate 15 in the noise Acoustic Wave Propagation that rack produces, acoustic wave segment will be absorbed, and remaining Acoustic Wave Propagation will be obstructed, and be forced to change direction and propagate to both sides and absorbed by the sound-absorbing section bar 21 of both sides.
A kind of preferred mode, the sound-absorbing section bar 22 of described baffle plate 15 windward sides can be set to the shape that the cross section is taper, and wherein, the bottom is fixedly connected with described baffle plate 15, and the top is towards the air inlet in air channel.Like this, sound wave can be better propagated and the sound-absorbing section bar 21 that be absorbed and be directed to both sides along hypotenuse along taper sound-absorbing section bar 22 hypotenuses.
