Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
See shown in Fig. 1 to Fig. 4, according to embodiment of the present utility model, the spiral case 2 that air channel structure comprises shell 1 and is arranged in shell 1, spiral case 2 has volute outlet 3, shell 1 also comprises the plenum chamber 4 be communicated with volute outlet 3, the first end being provided with the first deflector 5, first deflector 5 in plenum chamber 4 is connected on the sidewall of volute outlet 3, and the second end of the first deflector 5 is connected on the sidewall of plenum chamber 4.Between the volute outlet 3 that first deflector 5 is arranged on the dead angle area position, right angle of plenum chamber 4 and the sidewall of plenum chamber 4, other spaces of right angle dead angle area and plenum chamber 4 can be kept apart, thus fluid can be stoped after volute outlet 3 flows out to enter into right angle dead angle area.
First deflector 5 makes the flowing of fluid be transitioned into the sidewall of shell 1 gradually from volute outlet 3, and the right angle dead angle area that can not flow in plenum chamber 4, guide functions can be played to the fluid flowed out from volute outlet 3, fluid is moved along the water conservancy diversion direction of the first deflector 5, thus fluid can be avoided after volute outlet 3 flows to plenum chamber 4 to enter right angle dead angle area by the first deflector 5, reduce the whirlpool formed around the corner simultaneously, reduce the eddy-current loss of fluid, reduce noise and energy loss, improve fluid issuing speed and flow.
First deflector 5 is arc, and the sidewall of arc and volute outlet 3 is tangent, can make to seamlessly transit between the sidewall of arc and volute outlet 3, makes fluid enter in plenum chamber 4 more smoothly, reduces the noise in process fluid flow and energy loss.
The sidewall of arc and plenum chamber 4 is tangent, after fluid flows to the sidewall of plenum chamber 4 along the first deflector 5, can reduce the resistance in the sidewall fluid flow process of plenum chamber 4 further, reduce the noise in process fluid flow and energy loss.
The edge, direction that first deflector 5 flows out along fluid to air outlet is set to the first laciniation 6, first laciniation 6 and comprises multiple equally distributed sawtooth, and the addendum angle of each sawtooth is less than 90 degree.Fluid, flowing in the process of air outlet in plenum chamber 4, through the sawtooth of the first laciniation 6, can eliminate the afterbody eddy current of fluid by sawtooth, reduce fluid and to flow the noise caused.
Further, the first end being also provided with the second deflector 7, second deflector 7 in plenum chamber 4 is connected to the middle part of volute outlet 3, and the second end of the second deflector 7 is connected on shell 1 wall relative with volute outlet 3.First deflector 5 and the second deflector 7 match, and fluid flowing can be divided into two passages, and fluid, along two passages, can flow to air outlet at a high speed swimmingly.
Second deflector 7 comprises arc plate section 8 and straight plate section 9, and arc plate section 8 is arranged on the middle part of volute outlet 3, and tangent with the pelvic outlet plane of volute outlet 3, and the two ends of straight plate section 9 are connected on arc plate section 8 and shell 1 respectively.Arc plate section 8 can play guide functions to the fluid flowed out from volute outlet 3, reduce the energy loss in process fluid flow, and the flow direction of alter, make fluid to the direction flowing being more convenient to flow out air outlet, straight plate section 9 can play the effect of rectification and isolation, make the circulation passage forming two isolation in plenum chamber 4 better on the one hand, can not have an impact each other, rectification can be carried out on the other hand to fluid, the flow efficiency of further raising fluid, increases exit velocity and the rate of discharge of fluid.
The edge, direction that second deflector 7 flows out along fluid to air outlet is set to the second laciniation 10.Second laciniation 10 comprises multiple equally distributed sawtooth, and the addendum angle of each sawtooth is less than 90 degree.Fluid, flowing in the process of air outlet in plenum chamber 4, through the sawtooth of the second laciniation 10, can eliminate the afterbody eddy current of fluid by sawtooth, reduce fluid and to flow the noise caused.
Be illustrated for the course of work of gas flowing to air channel structure below.
Shell 1 and spiral case 2 are all airtight metal shells, ensure that the sealing of whole gas passage.Wind wheel starts High Rotation Speed under the drive of motor, and ambient atmos enters in air channel structure from air inlet.Enter the air of air channel structure inside, flow out along the tangential direction of the inwall of the volute outlet 3 of spiral case 2 under the drive of wind wheel.After gas is thrown out of along the tangential direction of the inwall of volute outlet 3, at volute outlet 3 place, gas be divide into two passage aisles by the first deflector 5 and the second deflector 7, and gas, along two passages, can flow to air outlet at a high speed swimmingly.
Second deflector 7 is in the centre position of volute outlet 3, and it is tangent with the pelvic outlet plane of volute outlet 3, first deflector 5 is tangent with the inwall of volute outlet 3, and it is tangent with the inwall of shell 1, so just can eliminate the flow blind angle region that gas is formed in right angle corner when volute outlet 3 flows out and enters plenum chamber 4, reduce the whirlpool formed around the corner simultaneously, reduce the eddy-current loss of gas.Flow out because gas is divided into two passages, which improves the exit velocity of gas, ensure that the rate of discharge of gas.
When gas flows out along band the first deflector 5 of sawtooth and the second deflector 7 to air outlet, due to the effect of sawtooth, can eliminate the afterbody eddy current of gas, reduction gas flows the noise caused.
According to embodiment of the present utility model, air-conditioner comprises air channel structure and is arranged on the wind wheel 11 in air channel structure, and this air channel structure is above-mentioned air channel structure.
Air channel structure is preferably centrifugal air duct, and wind wheel 11 is preferably centrifugal wind wheel.
Certainly, be more than preferred embodiment of the present utility model.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model general principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
