Abstract

The utility model discloses a silencing case, comprising a case body 1, silencing channels 4 and a closed separator plate 5, wherein the case body 1 is provided with an air inlet and an air outlet, two corresponding sides of the case body 1 are provided with the silencing channels 4, the inner walls of the silencing channel 4 are equipped with a sound absorption material, and the closed separator plate 5 is connected with one end of the silencing channel 4. The silencing case enables the air input and output path of an electronic device to be prolonged, and enables the sound absorption material to be mounted on the air input and output path for sound absorption, and enables a seal structure to be arranged on an air input and output channel to play an effect of sound separation, thereby playing an effect of noise reduction.

Description

Quiet case

Technical field

The utility model relates to a kind of noise-abatement equipment, relates in particular to a kind of quiet case that is applicable to electronic equipment.

Background technology

The electronic equipment of forced air cooling is owing to adopt fan as refrigerating plant; Itself has noise source; And increasing at present residential building, office, stair-corridor, hotel guest-room, the hospital ward etc. of being penetrated into of this kind equipment have people's activity and recreating facility; And this type place is higher to noise requirements, especially at night.The noise of electronic equipment also need satisfy noise of social activities emission limit standard except that satisfying the industry standard, and at present simple slave unit itself carries out noise reduction and has been difficult to meet the demands.

Summary of the invention

The utility model embodiment provides a kind of quiet case, mainly is applicable to electronic equipment, is used to reduce the noise of the electronic equipment that has forced air cooling now.

A kind of quiet case comprises casing, noise elimination passage, airtight baffle; Said casing is provided with air inlet and air outlet; The corresponding both sides of said casing are provided with the noise elimination passage, and the inwall of said noise elimination passage is equipped with acoustical material; Said airtight baffle links to each other with an end of said noise elimination passage.

Said acoustic absorbant is cotton for sound absorption.

Said quiet case also comprises Air Filter, and wherein, said Air Filter is arranged on the air inlet place of casing.

Said airtight baffle is two.

Said seal diaphragm is made up of metal or plastics.

The utility model adopts this " S " type air channel structure; Prolonged electronic equipment turnover wind path footpath; And on turnover wind path footpath, paste the acoustic absorbant sound absorption; The hermetically-sealed construction that passes in and out the wind air channel simultaneously plays the effect of sound insulation, is equivalent to inlet and outlet and has all installed a sound suppressor additional, thereby play the effect of noise reduction.

Embodiment

The quiet case that adopts the utility model embodiment to provide can effectively reduce the noise of electronic equipment, and noise reduction is 8～10dB.To combine accompanying drawing and specific embodiment that the technical scheme of the utility model is further set forth in detail below.

Shown in Fig. 1～3, the utility model embodiment provides a kind of quiet case, comprising casing 1, noise elimination passage 4 and airtight baffle 5; Introduce for ease, the casing 1 here be a rectangular shape, and both sides are provided with noise elimination passage 4 respectively about casing 1 corresponding, and air inlet is positioned at casing 1 left side, and air outlet is positioned at casing 1 right side; The concrete structure of said quiet case is following: the inwall of noise elimination passage (4) is equipped with acoustical material, and preferably, this acoustical material is sound absorption cotton 3; Airtight baffle (5) links to each other with an end of said noise elimination passage (4), and wherein, this airtight baffle 5 is made up of metal or plastics.

Preferably, at the air inlet place Air Filter 2 is set, in practical application; Said Air Filter 2 can be installed in the leftmost side, also can be installed in the rightmost side, according to the air channel structure decision installation site of equipment; If the internal unit air channel is the right side advance that a left side goes out or under go out on advancing, Air Filter is installed in the left side; If the internal unit heat dissipation wind channel is a left side advance that the right side goes out or enterprising under go out, then Air Filter is installed in the right side.

As shown in Figure 4, the utility model provides the quiet case of placing electronic equipment in a kind of casing, introduces for ease, and the inside wind direction of electronic equipment 6 is that the right side is entered a left side and gone out here, and air inlet is positioned at casing 1 left side simultaneously, and air outlet is positioned at casing 1 right side; The principle of work of said quiet case is following: wind gets into from the air inlet in casing 1 left side, and wind gets in the noise elimination passage 4 through Air Filter 2, and the inwall of noise elimination passage 4 is equipped with cotton 3 sound absorptions of sound absorption; Noise elimination passage 4 tail ends link to each other with airtight baffle 5, and air is under the effect of electronic equipment internal fan suction, and change of the wind left; Air intake vent enters into electronic equipment internal from the right side, goes out from the electronic equipment left side, and the left side air outlet links to each other with casing 1 inner airtight baffle 5; To pass in and out wind and isolate, seal diaphragm 5 links to each other with air outlet noise elimination passage 4, cotton 3 sound absorptions of noise elimination passage 4 inner installation sound absorptions; Noise further reduces; The space is left in the bottom, and air-flow flows through from noise elimination passage 4 lower space, discharges from quiet casing right side.

The above; Be merely the preferred embodiment of the utility model; Be not the protection domain that is used to limit the utility model, any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
