Description
Technical field
The present invention relates to a kind of air cooling-down humidifying technology field, particularly relate to a kind of spray axial fan.
Background technique
Spray axial fan is used for textile air-conditioner and carries out the visual plant that temperature and humidity is regulated.Present existing spray axial fan all adopts the secondary splitting principle to giving water atomization, even water inlet film forming and cut apart atomizing through draught fan impeller, the drop diameter that this secondary splitting produced is tiny inadequately, thereby influence wet exchange of heat between air and the water droplet; Dynamic balancing has a significant effect the residuary waters in axial fan hub water cover of intaking on the other hand to blower fan, and the not only total confluent of this blower fan is little, and the residuary waters in the wheel hub increases the additional load of motor, and the life-span is also lower.
Former mist-spraying cooling fan efficient is low, and main cause is that the blower fan injection flow rate is not enough, and the water droplet atomizing is tiny inadequately, thereby causes the mist-spraying cooling fan refrigerating capacity low.Former mist-spraying cooling fan comprises aqueduct, wheel hub, blade, fan casing, motor; The blade face type is the straight plate of steel, can't satisfy textile air-conditioner temperature and humidity needs.
In view of above shortcoming, be necessary to design change again to draught fan impeller structure and blade, promote the mist-spraying cooling fan refrigerating capacity, improve fan efficiency.Satisfy the textile air-conditioner temperature and humidity and regulate needs.
Summary of the invention
The objective of the invention is:
The invention provides a kind of water that makes and carry out the repeated segmentation atomizing, form ultra-fine diameter droplet, realize air-supply and the wing blade spray axial fan of spraying synchronously, having stronger overload capacity.
Technological scheme of the present invention is:
A kind of wing blade spray axial fan, this wing blade mist-spraying cooling fan comprise diversion cover, wheel hub, wing blades, preparatory atomizing wheel, Blower Housing, turn one's coat dish, motor; Wherein, the diversion cover is prepended to axial fan hub, and the wheel hub center is installed on the preparatory atomizing wheel of feedwater; Atomizing wheel is processed four blade profile turbine shrouds in advance; The rotation of atomizing wheel and wheel hub is synchronous in advance, and the axial and osculum that radially evenly distributes of wheel hub, horizontal preceding blade face of airfoil blade and end face are distributed with folding water raised line.
Advantage of the present invention is:
Compare with original blower fan, unit air volume of the present invention improves 36%, and efficient improves 35%, carries unitary current near under the identical situation at (feedwater) band, and maximum confluent improves nearly 100%.

Embodiment
This wing blade mist-spraying cooling fan is made up of diversion cover 1, wheel hub 2, preparatory atomizing wheel 3, wing blades 4, Blower Housing 5, turn one's coat dish 6, motor 7 etc.; With preparatory atomizing wheel 3 is main member, and atomizing wheel is processed four blade profile turbine shroud structures in advance, at wheel hub 2 inner chambers preparatory atomizing wheel 3 is installed; Atomizing wheel 3 is an one with wheel hub 2 assembly weldings in advance, and is coaxial with motor 7, and wheel hub 2 circumferentially reaches preparatory atomizing wheel 3 chassis and radially is uniformly distributed with brill 10-Φ 8mm hole respectively; Wheel hub 2 peripheral apertures are positioned at wing blades 4 preceding blade faces, and the dish 6 of turning one's coat is installed in wheel hub 2 outsides, with wheel hub spacing 8-10mm; Dish 6 square with the axis of the exterior rim bending inclination angles of turning one's coat are 30 °, so that annular moisture film refraction imports fan blade cutting atomizing, wing blades 4 is single blade profile; Material is a cast aluminium alloy, and blade middle part, preceding blade face and end are designed to the 3mm height respectively, the folding water raised line that 5mm is wide; Be used for the water that penetrates from wheel hub 2 circumferential osculums is reflected the bump atomizing; Diversion cover 1 is processed the porous spray structure, and water inlet aperture and hole count all are less than or equal to total water outlet aperture and hole count in the wheel hub 2, to avoid in the wheel hub 2 residuary waters to dynamically balanced influence.
Because this wing type fan wheel hub inside is provided with preparatory atomizing wheel; When the preparatory atomizing wheel of preposition diversion cover feedwater process, produce the first cutting and separating of feedwater; Under the action of centrifugal force of preparatory atomizing wheel, penetrate to reaching the axial bore pressure through the precut water trailing wheel hub diameter that separates, make wheel hub inside not produce remaining ponding; Thereby obviously reduced the additional load of blower fan, the stability of blower fan is obviously improved; By hub spindle to and the water that penetrates of radial hole under the blower fan action of negative pressure; Preparatory atomized water cutting apart once more through rotation blade; Form average drop diameter less than the fine liquid particles below the 0.14mm, when blade was to preparatory atomized water cutting, the folding water raised line on the wing blades formed the refraction bump to water once more; Form three times cutting and separating, obtain the ultra-fine particle water that average drop diameter is not more than 0.1mm.
With the approximate power-performance contrast of the similar blower fan of present application, through test, performance advantage is following:
Table 1 fan performance parameter comparison table
Test shows: after the improvement, the blower fan unit air volume improves 36%, and efficient improves 35%, carries unitary current near under the identical situation at (feedwater) band, and maximum confluent improves nearly 100%.
