Description
Technical field
The utility model relates to refrigerating field, more specifically, relates to a kind of cross flow fan and has its air conditioner.
Background technique
Cross flow fan is at industrial cross-flow fan, the linear flow formula blower fan of often being called again.Referring to Fig. 1 and Fig. 2, cross flow fan comprises: the air channel of tubular wine wheel 3 and cross flow fan, and the air channel of cross flow fan is formed by the turnover wind passage that back wind-guiding spiral case 2 and snail tongue disjunctor spiral case 1 are surrounded, and the indicated scope of A is the air intake scope of cross flow fan among the figure.In conjunction with reference to figure 1 described air conditioner structure, as can be seen, cross flow fan is arranged in the air-conditioner shell, and air enters air-conditioner shell inside from the air-inlet grille 5 of air conditioner, discharges from the ducting system of cross flow fan after being arranged on vaporizer 4 heat exchange between through-flow fan blade and the air-inlet grille.This cross flow fan structure is simple relatively, has thin and elongated outlet, does not change the characteristics such as flow direction of air-flow substantially.The dynamic pressure of this cross flow fan is higher, air-flow not disorderly, can produce flat and at a high speed air-flow, and air-flow is laterally even, the time of arrival is long, noise is lower.Along with the raising of people's living standard, the noise requirements in work and the life is also improved constantly, the aerodynamic characteristic of cross flow fan and the reduction of noise are proposed higher requirement.
The cross flow fan noise figure depends primarily on aerodynamic noise, is caused by inhomogeneous the flowing of air in cross flow fan.Aerodynamic noise generally includes two parts, i.e. rotational noise and turbulence noise.The characteristics of rotational noise are frequency-distributed, so claim the discrete frequency noise again; Turbulence noise claims eddy current crack again, its feature is the frequency broad, be the continuous frequency spectrum noise, so also claim broadband noise, it is because during the airflow passes blade, produce turbulent boundary layer and vortex and vortex division lift-off, and cause what the pulsation of blade upward pressure caused, it is another main noise source of cross flow fan.Rotational noise concentrate on usually noise spectrum in, low-frequency range, people's ear is comparatively responsive; Turbulence noise then is a continuous spectrum, does not influence tonequality usually.
Cross flow fan inner air mobile (abbreviating the Nei Liu district as) depends on two aspects, the position and the size of the Nei Liu district eccentric vortex that first snail tongue disjunctor spiral case 1 is determined; It two is that the tubular wine wheel exit flow speed of the form decision of back wind-guiding spiral case 2 is converted into static pressure.Because back wind-guiding spiral case 2 is that the concentric circle in the center of circle is revised with cross flow fan eccentric vortex center of vorticity position, so the whole air current flow of cross flow fan is subjected to having the greatest impact of snail tongue disjunctor spiral case 1.Snail tongue disjunctor spiral case 1 is again by snail tongue 10 and installation matrix thereof---and preceding wind-guiding spiral case 12 constitutes, and the molded lines of preceding wind-guiding spiral case 12 is generally camber line or the straight line with the airflow direction basically identical.The position of Nei Liu district eccentric vortex and size depend on the gap (abbreviating the snail tongue room as) of tubular wine wheel and snail tongue disjunctor spiral case 1, the snail tongue room here mainly by the determining positions of snail tongue 10 with tubular wine wheel 3, therefore determines that the key factor of cross flow fan performance and noise is the structural design of snail tongue 10.Change snail tongue 10 shape and and tubular wine wheel 3 between the gap, also just changed the size and the position of snail tongue room.The sectional shape of snail tongue 10 can be isocentric circular arc or non-isocentric circular arc with tubular wine wheel 3.Can sum up from basic flow mechanism and some test result of cross flow fan: when the snail tongue room was big, flow regions such as the eccentric vortex core district in Nei Liu district, circulating reflux district, interior recirculating zone increased.Because eccentric vortex increases, the circulating air flow of tubular wine wheel inside increases, and the through-flow zone reduces, and has reduced the aerodynamic noise of cross flow fan, but noise when reducing the through-flow air quantity of cross flow fan reduce.Suitably reduce the whirlpool tongue room, the circulating air flow of tubular wine wheel inside is reduced, the main flow area flow increases, thereby increase the flow and the pressure head of cross flow fan, but too small snail tongue room will increase the resistance of system, and cross flow fan efficient is reduced, thereby reduce the performance of whole cross flow fan, as air quantity, blast etc., and the aerodynamic noise of cross flow fan is improved.
An effective means that reduces the cross flow fan rotational noise is that the blade that prevents tubular wine wheel 3 is circumferentially evenly arranged, for example Chinese patent application number is to announce in 99106786,95100629,00123848, and mode can reduce rotational noise to adopt the blade of more piece combination tubular wine wheel segmentation arranged in dislocation, irregular pitch circumferentially to distribute, blade lean is installed, every group of blade evenly increases angle etc.Wherein adopt the blade of irregular pitch circumferentially to distribute, can improve cross flow fan internal flow state, make mobile more even.
At snail tongue design aspect, people have also designed the spiral case molded lines (comprising back wind-guiding spiral case 2 and snail tongue disjunctor spiral case 1) of two-dimensional characteristics by the duality that flows according to the cross flow fan inner air, suppress the generation of turbulent flow and the noise that causes thereof by optimizing the spiral case molded lines.In addition, the patent No. is ZL200520063602.8, application number is that 200810199001.8 patent is respectively from the angle of discrete rotational noise frequency spectrum, proposed in the axial direction the spiral case molded lines to be designed again, the snail tongue is axially being transformed, make the snail tongue have the three dimensional design feature, with the snail tongue be parallel on the axial direction of running shaft and the tubular wine wheel outer rim of tubular wine wheel between distance be changing value, make dentation, corrugated or oblique twisted shape in the axial integral body of snail tongue, to suppress the higher harmonics of tubular wine wheel, reduce noise.
But, because tubular wine wheel 3 does work to gas when high speed rotating, tubular wine wheel itself can also be subjected to the effect of the anti-force of air-flow, the position of the eccentric vortex of cross flow fan internal flow also is in a kind of motion state, the active force that blade pass is said stream and snail tongue 10 also is a kind of pulsating force, so tubular wine wheel 3 also is in radial and axial swing state when rotated; With the turning axle system of tubular wine wheel 3 as a two ends freely-supported, because tubular wine wheel 3 inevitably has certain flexibility, and the dynamic balance performance of tubular wine wheel 3 is in certain scope, and the radial displacement meeting of tubular wine wheel 3 intermediate portions is greater than the displacement at two ends.Aforementioned two kinds of factors, make tubular wine wheel 3 produce radial and axial vibration when rotated, can make more piece combined type tubular wine wheel inside not only produce the axial motion air-flow, also make center of vorticity be in a kind of state of beating, obviously, this vibration mode is very disadvantageous for the performance and the noise of cross flow fan, makes the inhomogeneous air-flow of cross flow fan intermediate portion become the main noise source of tubular wine wheel.
And in above-described a plurality of patent, all vibration factors such as reaction force that tubular wine wheel 3 is not produced because of rotation and centrifugal force take in, so cross flow fan is not had specific aim because of the uneven noise that produces of air current flow that above-mentioned vibration factor causes.The perseverance of using is all not ideal enough apart from the effect that snail tongue (general designation straight line snail tongue) cross flow fan reduces the overall noise and the thorn power of hearing at present; Dentation and oblique twisted shape impermanent in snail tongue cross flow fan need all be made dentation on the whole length of snail tongue, complex-shaped, the big cost of preparation process difficulty is also high.Therefore, design snail tongue of transforming a kind of main noise source position that is produced at tubular wine wheel whirling vibration state and the cross flow fan of using this snail tongue, very big meaning is arranged improving total noise of centrifuge.
