It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig.1, hanging the machine of falling includes shell 300, and partition 320 is provided in shell 300, and partition 320 will be in shell 300
Portion space is separated into air-inlet cavity and air-out chamber.Air-inlet cavity side is provided with spiral case 100, and fan 200 is provided in spiral case 100, the wind
Fan 200 is centrifugal fan.Air-inlet cavity side is additionally provided with air inlet (not indicating), and air inlet is provided with air intake grid 400 and should be into
Air port is connected to spiral case air inlet (not indicating).The through-hole for being connected to spiral case air outlet 110 is provided on partition 320 (not mark
Show), spiral case air outlet 110 passes through the through-hole.Air-out chamber side is provided with air outlet 310.Air outlet 310 and spiral case air outlet 110
Between be tiltedly installed with heat exchanger 600, the lower section of heat exchanger 600 is provided with drip tray 700.Hang the airflow circulating route in the machine of falling
Are as follows: the air-flow entered from air inlet enters in spiral case 100 through spiral case air inlet, from spiral case outlet air under the action of fan 200
Mouthfuls 110 flow out, then after the heat exchange of heat exchanger 600 from air outlet 310 from flow out.
Disclosed by the utility model hang falls machine supply air system, mainly passes through and rationally designs 120 radius of volute tongue, spiral case 100
Throat width B, the exit width L of spiral case air outlet 110, the angle of flare α of spiral case air outlet 110, spiral case air inlet diameter, fan
The data such as the gap between 200 diameters, volute tongue 120 and fan 200, factor is set out to reduce the noise for hanging the machine of falling from many aspects.
Specifically, the coboundary extended line A of design spiral case air outlet 110 is overlapped with the upper limb for the air outlet 310 for hanging the machine of falling,
The lower boundary extended line B of spiral case air outlet 110 is overlapped with the lower edge for the air outlet 310 for hanging the machine of falling.In this way it is possible to prevente effectively from
Interference between boundary extended line A and the shell 300, lower boundary extended line B and drip tray 700 that hang the machine of falling, avoids the formation of reflux,
To which noise be effectively reduced and the outlet air efficiency of complete machine can be improved.Due to avoiding reflux, also just avoids and drawn by reflux simultaneously
The uneven distribution of wind speed on the heat exchanger 600 risen further facilitates to reduce noise.
Under the principle based on above-mentioned design, by multiple factors that will affect noise in spiral case 100, fan 200
Progress is repeatedly tested repeatedly, is finally determined under the premise of guarantee hangs and falls machine performance, can be maximally reduced noise
Each factor parameter.
Referring in particular to Fig. 2: the cross-section curve of spiral case 100 is log spiral, and the helical angle of the log spiral takes
Being worth range is 4.7 ~ 6 °, by increasing spiral case inlet pressure, the air-flow of rotation is made to have enough diffusion spaces.
Appropriate to reduce 200 diameter D0 of fan, i.e. the value range of design 200 diameter D0 of fan is 145 ~ 155mm, increases gas
The rotation efficiency of fan 200 is improved in the acting space of stream.
120 radius r of volute tongue has no significant effect the performance of blower, but very big to noise effect, rationally designs volute tongue 120
Gas can be effectively prevented in 100 internal circulation flow of spiral case in radius r, helps to reduce noise, 120 radius r of the present embodiment volute tongue
Value range be 8 ~ 12mm.
In order to guarantee that the air-flow blown out at volute tongue 120 does not occur refluence phenomenon, avoid in spiral case air inlet and spiral case
Occurs violent whirlpool in space between 100, to reduce the pneumatic noise of blower.The throat width B of the present embodiment spiral case 100
Value range be 75 ~ 92mm, the value range of the exit width L of spiral case air outlet 110 is 97 ~ 120mm.
In order to enable the air-flow entered from spiral case air inlet to be uniformly full of the entrance section of fan 200, and protect
Drag losses minimum when air-flow passes through spiral case air inlet is demonstrate,proved, facilitates decrease vortex, control is flow backwards, reduction noise, the present embodiment
The value range of spiral case air inlet diameter D2 is 123 ~ 138mm.
In order to reduce the leakage of the gas between the blade of fan 200 and spiral case 100, reinforce the fixation to blade, this implementation
It is provided with fan stiffening ring (not indicating) on example fan 200, the value range that fan reinforces loop diameter D1 is 150 ~ 160mm.
Due to the direction deflection that the outlet air air-flow of spiral case 100 is rotated to fan 200, in order to avoid flowing backwards, reducing noise, snail
The direction that the angle of flare α of shell air outlet 110 is also rotated towards fan 200, the exit width L and spiral case of comprehensive spiral case air outlet 110
The length of air outlet 110, the value range of the angle of flare α of the present embodiment spiral case air outlet 110 are 8 ~ 15 °.
Clearance t between volute tongue 120 and fan 200 will affect the aeroperformance of blower, have large effect to noise.Between
Gap t is too big, and the aeroperformance of blower reduces；Clearance t is too small, and the noise of blower increases.The present embodiment volute tongue 120 and fan 200
Between clearance t value range be 3 ~ 7mm.
In order to make the blade surface of fan 200 have suitable VELOCITY DISTRIBUTION, while guaranteeing higher pressure and efficiency,
Noise can be reduced again, and the present embodiment blade uses wing blades.Since the quantity of blade also has a certain impact to noise, with
The increase of blade quantity, whirlpool loss reduce, friction loss increases, so needing to select a kind of flow losses the smallest best
Blade quantity.The value range of the quantity of the present embodiment blade is 41 ~ 47.
The utility model solve the problems, such as to reduce hang the noise for the machine of falling while, to hanging electronic-control box 500 in the machine of falling
Maintenance convenience has also carried out structure improvement.The setting of electronic-control box 500 is connect in air-inlet cavity side, with partition 320, is located at air intake grid
400 top, spiral case air outlet 110 lower section.When maintenance, without disassembling entire electronic-control box 500, only by air intake grid
400 remove and can repair to electronic-control box 500.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
