Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The air-conditioner outdoor unit denoising device of the utility model embodiment comprises front panel 10, be opened in the air-ducting ring 20 that air outlet 11 on described front panel 10 and correspondence are arranged at described air outlet 11 place, air-flow passes described air-ducting ring 20 and is discharged by described air outlet 11, and the windward side periphery of described air-ducting ring 20 is outwards formed with flange 21.
Described air-conditioner outdoor unit denoising device also comprises the noise reduction part 30 be arranged at inside described front panel 10, described noise reduction part 30 comprises the plate windward 31 be connected mutually with the described flange 21 of described air-ducting ring 20, described plate windward 31 offers some holes 32 that air feed flows through, be provided with cavity 33 between described plate windward 31 and described front panel 10, described cavity 33 is connected with described hole 32.
The utility model relative to the technique effect of prior art is: the windward side of noise reduction part 30 is designed with hole 32 (i.e. micropore).When off-premises station works, by the most of space outerpace blowing to air-conditioner outdoor unit by air-ducting ring 20 of the air-flow of heat exchanger, but because the flange 21 of air-ducting ring 20 affects, part air-flow has deflected away from air-ducting ring 20 and has blown to and front panel 10 internal face defines backflow and vortex flow, thus the level of noise increased with rear side side on the left of the noise of off-premises station inner chamber and the level of noise, particularly off-premises station at air outlet 11 place.By increasing the noise reduction part 30 of a band micropore at off-premises station air-ducting ring 20 place, flee from the airflow opening hole 32 of air-ducting ring 20, stream pressure, air velocity absorb by hole 32, weaken, effectively reduce backflow and the vortex flow of the formation of air-ducting ring 20 place, greatly reduce the noise of off-premises station inner chamber, the particularly level of noise of each point from all directions, reaches the object reducing off-premises station noise and improve off-premises station tonequality and sense of hearing comfortableness.
In order to make the better effects if of reduction noise, in the present embodiment, the described plate windward 31 of described noise reduction part 30 is concordant with the outer rim of described flange 21, makes the air-flow of being fled from by flange 21 pass plate 31 windward and more easily enters in cavity 33.
In the present embodiment, described noise reduction part 30 also comprises the baffle plate 34 extended towards described front panel 10 by the outer rim of described plate windward 31, and the periphery of described plate windward 31, described baffle plate 34, described front panel 10 and described air-ducting ring 20 forms described cavity 33 jointly.
In other embodiments, described noise reduction part 30 also comprises the baffle plate 34 that extended towards described front panel 10 by the outer rim of described plate windward 31 and is connected to the coaming plate (not shown) extended on described baffle plate 34 and towards the periphery of described air-ducting ring 20, the periphery of described baffle plate 34, described plate windward 31, described coaming plate and described air-ducting ring 20 forms described cavity 33 jointly, jointly forms described cavity 33 by the structure of noise reduction part 30 itself and the periphery of air-ducting ring 20.The sidewall that front panel 10 is used as cavity 33 replaced by coaming plate.
Above-mentioned noise reduction part 30 can be working of plastics, also can be sheet metal component or foam element.Foam element plays better effect to reduction noise.
Above-mentioned hole 32 can arbitrarily be distributed in windward on plate 31 and the pitch-row H of adjacent described hole 32 within 10mm, preferably, described in described some holes 32 are distributed in windward on plate 31 and the pitch-row H of adjacent described hole 32 within 10mm.
Further, the cross section of each described hole 32 is become large trend gradually on the flow direction of air-flow.Air-flow progresses in open space when being flow through by hole 32, and make the flow velocity of air-flow, stream pressure clearly reduces, the design of the cross section of hole 32 like this, noise reduction is better.Preferably, the cross-sectional diameter of each described hole 32 is minimum is 5mm.
In the present embodiment, described noise reduction part 30 is spliced by multiple splice (not shown), and multiple described splice is located in described air-ducting ring 20 around.The operability of assembling is increased by the splicing of each splice.
The quantity of splice can be two or more than two, particularly for two, two splices are positioned at the left and right sides of air-ducting ring 20, and so latter two fitting combination assembling is stuck in the groove of air-ducting ring 20, and then is fixed on front panel about 10 both sides.
The utility model embodiment also provides a kind of air-conditioner outdoor unit ducting system applying above-mentioned air-conditioner outdoor unit denoising device, and it comprises shell, the heat exchanger be installed in described shell, be positioned at the blower fan of described heat exchanger side.Not shown shell, heat exchanger and blower fan here, but shell, heat exchanger and blower fan are common structure, do not add repeat at this.Described shell comprises described front panel 10, and the exhaust outlet of described blower fan is corresponding with described air-ducting ring 20.Air-flow through over-heat-exchanger, blower fan and noise reduction part 30, is finally discharged by air outlet 11 successively.
The air-flow departing from air-ducting ring 20 part cannot form backflow and vortex flow after micropore (i.e. hole 32), thus significantly reduces the noise with left side on rear side of off-premises station, optimizes inside cavity noise, reduces the level of noise at air outlet 11 place.The utility model, by adopting micropore noise reduction sound technology, optimizes the air-flow of off-premises station inner chamber, significantly reduces off-premises station level of noise from all directions, significantly improve the tonequality of off-premises station noise and the comfortableness of the sense of hearing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
