Abstract
The invention provides a low-noise case, which comprises an air inlet channel, an air outlet channel and a muffling channel, wherein the air inlet channel is formed on one side of the case, and a radiating air inlet fan is arranged in the air inlet channel; the air outlet channel is formed in the case and on the side opposite to the air inlet channel, and a radiating outlet fan is arranged in the air outlet channel; and the muffling channel is connected and arranged between the air inlet channel and the air outlet channel, a heating part needing radiation is arranged in the muffling channel, and the radial area of the muffling channel is greater than the radial area of the air inlet channel and the air outlet channel. In the invention, the radial area of the muffling channel is greater than those of the air inlet channel and the air outlet channel, a wide muffling cavity is formed in the muffling channel, so that a sound wave channel has a sudden change in cross section to stop sound wave transmission and eliminate noises.
Description
Technical field
The present invention relates to a kind of low noise cabinet.
Background technology
At present, along with the upgrading of computer function, high power consumption parts increase in the computing machine, and the computing machine internal heat generation is more and more, and this just requires computing machine that higher heat dispersion is arranged.The main heat dissipating method of computing machine is air-cooled, adopts the method for blowing to make that the heat of heat generating components generation is taken away rapidly.Air cooling way is simple, cost-effectively is low, and irreplaceable advantage is arranged.But along with computing machine is more and more higher to the requirement of heat radiation, air-cooled middle fan power improves thereupon, to reach corresponding heat radiation requirement.The raising of fan power has brought new problem, and that produces exactly than high noisy, influences operator's use, when serious the people can't be stood.In addition, the modern humans more and more payes attention to environmental protection, and noise pollution also is that people institute is insupportable.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of have high heat dispersion and the low air-cooled cabinet of environmental protection of noise.
In order to address the above problem, the invention provides a kind of low noise cabinet, comprising:
Air inlet duct, described air inlet duct are arranged on a side in the cabinet, are provided with the air intake fan that is used to dispel the heat in the described air inlet duct;
Exhaust passage, described exhaust passage are arranged on a side relative with described air inlet duct in the described cabinet, are provided with the air-out fan that is used to dispel the heat in the described exhaust passage;
Silencers channel, described silencers channel connect and are arranged between described air inlet duct and the exhaust passage, are provided with the heat generating components that needs heat radiation in the described silencers channel, described silencers channel radially area greater than described air inlet duct and exhaust passage area radially.
Further, described silencers channel madial wall is provided with the sound absorption lining.
Further, the described air inlet duct air inlet that the connects described cabinet air outlet that is connected described cabinet with described exhaust passage is provided with the porous metals silk screen.
Further, described sound absorption lining is sound-absorbing porous material.
Further, the radially area of described silencers channel be described air inlet duct and exhaust passage radially area 5-50 doubly.
The present invention has following advantage:
1, among the present invention silencers channel radially area is greater than air inlet duct and exhaust passage area radially, silencers channel forms roomy noise reduction inner chamber, makes the sound wave conduction pathway area of section sudden change occur, thereby stops the sound wave conduction, reaches the purpose that abates the noise.
2, the sound absorption lining is set on the silencers channel madial wall of the present invention, can further abates the noise, make that noise of the present invention is littler.
3, the present invention is provided with the porous metals silk screen on air outlet and air inlet, also can further abate the noise under the situation that guarantees safety, promotes performance of the present invention.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the present invention are described further:
Fig. 1 shows a kind of low noise cabinet of the present invention noise reduction principle schematic;
Fig. 2 shows a kind of low noise casing structure of the present invention synoptic diagram.
Embodiment
As shown in Figure 1, A is an incident acoustic wave, and B is the emission sound wave.Noise reduction principle of the present invention is to be provided with the noise reduction cavity, makes the sound conduction passage area of section sudden change occur, influences sonic propagation, thereby effectively abates the noise.This noise reduction cavity utilizes pipeline section to expand (or shrink) suddenly and causes acoustic impedance sudden change in the passage, make along some frequency of pipe transmmision sound wave can't the reflected back sound source be gone by the noise reduction cavity.Because sound wave can't pass through this noise reduction cavity, just biography is not gone out yet, thereby reaches the purpose of noise reduction.
As shown in Figure 2, the present invention includes air inlet duct 1, exhaust passage 2 and silencers channel 3, C is a wind direction.Air inlet duct 1 is convenient to ventilate with exhaust passage 2, can abate the noise in the silencers channel 3.
The air inlet 12 that air inlet duct 1 connects cabinet 4 is connected cabinet 4 with exhaust passage 2 air outlet 22 is provided with porous metals silk screen 5.The present invention is provided with porous metals silk screen 5 on air outlet 22 and air inlet 12, also can further abate the noise under the situation that guarantees safety, promotes performance of the present invention.
Radially area is greater than air inlet duct 1 and exhaust passage 2 area radially for silencers channel 3 among the present invention, and silencers channel 3 forms roomy noise reduction inner chamber, makes the sound wave conduction pathway area of section sudden change occur, thereby stops the sound wave conduction, reaches the purpose that abates the noise.
The present invention also can be arranged on the electronic unit that does not need to dispel the heat according to actual needs and be positioned at air inlet duct 1, exhaust passage 2 and silencers channel 3 zone in addition in the cabinet 4, to improve usability of the present invention.
The present invention realizes reducing the purpose of noise by cabinet 4 structural designs, can not increase fringe cost, also can not reduce cabinet 4 space availability ratio, and is economical and practical, has excellent popularization to be worth.
In sum; being preferred embodiment of the present invention only below, is not to be used to limit protection scope of the present invention, therefore; all any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
