Abstract
The utility model relates to an axial fan, in particular to an improvement to the high power axial fan for high-temperature operation. The utility model comprises a fan impeller 1, a rotor, a stator and an outer housing, and is characterized in that the impeller 1 is made from magnesium alloy material with a good thermal conductivity by die casting processing, two improvements (weighting or lightening) are provided on the wheel flange 5 of the impeller 1 due to the adoption of magnesium material and for better solving the problem of dynamic balancing after the change of material, the two improvements provide an axial hole 7 on the wheel flange and a groove 8 on the inside wall of the wheel flange. The obvious effect is that the weight of the part is reduced by 75 percent, the air-quantity of the fan is increased, the power of the motor, the temperature rising and the noise are reduced, thus the service life of the fan is prolonged.
Description
Technical field
The utility model relates to axial-flow blower, refers to the structure of the more powerful axial-flow fan blade that a kind of high temperature occasion is used especially.
Background technique
The special more powerful axial-flow blower that uses in the high temperature occasion, as BI-SONIC5E230B type blower fan, generally can not adopt the die casting mode to process, therefore, its fan blade generally adopts PBT material or steel material to make, its relative weight is heavy, so motor load is also big, and owing to its friction factor is relatively large noise is also big.Usually cause thus and cause that motor windings is overheated and burn because of aeration-cooling condition is not good.
Summary of the invention
A kind of axial-flow blower of the utility model, be for solving the more powerful axial-flow blower that uses in the high temperature occasion especially as previously mentioned, as BI-SONIC5E230B type blower fan, generally can not adopt the die casting mode to process, therefore, its fan blade generally adopts PBT material or steel material to make and the disadvantages of existence.
The fan blade of the utility model axial-flow blower adopts the splendid magnesium alloy materials of thermal conductivity that is shaped through die-casting process to make, owing to adopted magnesium alloy materials, its significant effect is: make this a part of weight descend 75% especially, the air quantity of blower fan is increased, power of motor, electric machine temperature rise and noise reduce, and blower fan prolongation in working life etc. are effect actively.Meanwhile solve preferably because of more carrying out the consideration that dynamic balancing is regulated behind the conversion materials, on the wheel rim of fan blade, be provided with two kinds of (increasing the weight of or loss of weight) corrective measures, promptly on wheel rim 5 is axial, aperture 7 is set and wheel rim 5 inwalls are provided with groove 8.
Description of drawings
Fig. 1 is the blade structure schematic representation of prior art;
Fig. 2,3 is two kinds of dynamic balancing point of adjustment of the utility model structural representation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
A kind of axial-flow blower is made up of fan blade 1, rotor and stator and housing, and it adopts fan blade 1 wheel rim of making through the magnesium alloy of die casting 5 to be provided with a dynamic balancing point of adjustment.
An embodiment of the present utility model, its described axial-flow blower, its dynamic balancing point of adjustment is positioned at wheel rim 5 aperture 7 on axially.
Another embodiment of the present utility model, described axial-flow blower, its dynamic balancing point of adjustment is positioned at the groove 8 of wheel rim 5 inwalls.
In sum, the fan blade of the utility model axial flow blower adopts the thermal conductivity utmost point that is shaped through die-casting process Good magnesium alloy materials is made, owing to adopted magnesium alloy materials, its significant effect is to make especially this The weight of part has descended 75%, and the air quantity of blower fan is increased, power of motor, electric machine temperature rise and make an uproar Sound reduces, and service life of fan prolongation etc. are effect actively. Meanwhile solve preferably because of behind the conversion materials more Need carry out the consideration that dynamic balancing is regulated, be provided with two kinds (increasing the weight of or loss of weight) at the wheel rim of fan blade and improve Measure.
