Description

The computer quiet case

Technical field:

The utility model relates to noise reduction, the sound insulation technical field of computer, specifically, is a kind of computer quiet case of carrying out the noise reduction sound insulation for running host computer.

Background technology:

As everyone knows, it is very bored that the noise that host computer sends makes us, especially to the present age, along with the popularization and application of computer and people improving constantly and deeply to health requirements, people continually develop the product of the noise pollution that reduces CPU, video card and power supply fan etc., its prior art mode of combining has six kinds substantially: 1, strengthen fan diameter to reduce rotating speed, the collateral security air mass flow is started with and is reduced the noise source; 2, the lubricated form of improvement or change fan spindle bearing and bearing arrangement mode are to reduce vibrations; 3, replace fan straight blow type radiating sheet cooling (the outer cooling tower of its cabinet still needs heavy caliber, the heat radiation of slow-speed of revolution fan) with water cooling plant; 4, heater as: CPU, video card, north and south bridge etc. install heat conductivility better material such as copper, silver, heat pipe, semiconductor etc. additional, increasing radiating rate, and then reduce the number of revolution per unit of time of fan; 5, the steel plate and the supporting structure of thickening or reinforcement cabinet install the damping cushion additional, to reduce resonance; 6, on the cabinet inwall, mount noise reduction cotton, noise reduction film.

More than the main points and the principle of several technology, all be strengthening area of dissipation, to accelerate heat-transfer rate and attach most importance to, be that the characteristics at center are carried out to reduce rotation speed of the fan.And in this type of technology, confirm through market, the technology of tool actual effect, only " water-cooled " be best, but nonetheless, this technology also has maximum " in straitened circumstances ": 1, biography, heat pipe complexity and numerous; 2, there is leaked liquid machine to be caused the worry of crushing blow; 3, the peripheral hardware heating radiator is huge and take up room; 4, the external heating radiator needs fan for cooling and still has noise; 5, still need keep fan in the cabinet; 6, with former traditional actual comparing, noise reduction only is " having clear improvement "; 7, cost height is installed complicated.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of computer quiet case is provided, and mainly solves existing computer noise reduction, sound arrester complex structure, effect is undesirable, cost is high and problem such as complexity is installed.

In order to achieve the above object, the utility model is to realize like this, the computer quiet case, it comprises casing, its special character is that casing is by outer metal housing, pugging and sound absorbing layer are formed, in outer metal housing, establish pugging, in pugging, establish sound absorbing layer, the three is fixed together, in casing, establish the cabinet inner casing, the cabinet inner casing is made of interior betal can and sound-absorbing template, on the betal can, forms the air channel that connects between casing and cabinet inner casing in the sound-absorbing template is fixed on, set position blob of viscose and inner support between casing and the cabinet inner casing, on the interior betal can of cabinet inner casing, establish bigbore case fan, on the fore shell of casing, establish the CD-ROM drive position, the imprinting seat in the plane, control template and interface are established power knob on control template, Reast button and case fan speed governing button; Afterbody at the cabinet inner casing is established connector, chassis power supply is established on top at cabinet inner casing afterbody, on the outer wall of cabinet inner casing, establish the sound insulation exhaust box, the back plate of sound insulation exhaust box and the back plate of casing are one, form the cabinet of a sealing, the sound insulation exhaust box fan on the sound insulation exhaust box is corresponding with chassis power supply, and the outer wall of sound insulation exhaust box is made by abatvoix, in the sound insulation exhaust box, establish perpendicular put sound-absorbing bent plate and horizontal sound-absorbing bent plate, establish the air draft orifice plate in the lower end, rear of sound insulation exhaust box.

Computer quiet case of the present utility model, its described sound absorbing layer, sound-absorbing template and abatvoix are by acoustical material and sheet metal is compound makes, adopt individual layer or double-deck acoustical material with metal level single or double parcel, or directly make with wire netting, fibrous material mixing once formed type by acoustic absorbant; The described perpendicular sound-absorbing bent plate of putting is wrapped up metal level by individual layer or double-deck acoustical material with horizontal sound-absorbing bent plate or is directly mixed once with metal material by acoustic absorbant and make; Described perpendicular S type or the V-type bent plate that sound-absorbing bent plate and horizontal sound-absorbing bent plate can be multilayer of putting.

Computer quiet case described in the utility model is compared with existing technology has following good effect: 1, adopt the mode of isolated noise to reach the noise reduction purpose; 2, adopt the sound insulation exhaust box, under the prerequisite that does not influence heat extraction, cut sound, noise reduction sound insulation; 3, can be close to " completely cutting off " hard disk and read dish sound; 4, by market mainstream computer configuration at the beginning of 08, use PocketRTA software at night, A weighting test at night down, the sound vibrations frequency stabilization, noise significantly weakens, and almost can't hear main frame noise and host work at one meter of case of disembarking and stablizes.
