Abstract
The invention is an axial-flow fan. The fan of the prior art mainly adopts the PBT material or ionic materials that are heavy and have large friction coefficient and loud noise. The invention adopts the magnesium-alloys materials that have fine heat conduction, which reduces the weight by 75% and lowers the cost. And meanwhile it increases the fan delivery and electric machine power, and reduces the noises of the machine.
Description
Technical field:
The present invention relates to axial-flow blower, refer 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.Thus, usually cause 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 present invention is for solving the foregoing more powerful axial-flow blower that uses in the high temperature occasion especially, generally can not adopt the die casting mode to process, so its fan blade generally adopts PBT material or steel material to make and has a disadvantages.
The fan blade of axial-flow blower of the present invention 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, thereby the cost of transportation of product also obviously descends.The air quantity of blower fan is increased, and power of motor, electric machine temperature rise and noise reduce, and blower fan prolongation in working life etc. are effect actively.Meanwhile solve preferably, on the wheel rim of fan blade, be provided with two kinds of (increasing the weight of or loss of weight) corrective measures because of more carrying out the consideration that dynamic balancing is regulated behind the conversion materials.
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 present invention structural representation.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing:
A kind of axial-flow blower is made up of fan blade 1, rotor 2 and stator 3 and housing 4, 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 6.
One embodiment of the present of invention, its described axial-flow blower, its dynamic balancing point of adjustment 6 is positioned at wheel rim 5 aperture 7 on axially.
An alternative embodiment of the invention, described axial-flow blower, its dynamic balancing point of adjustment 6 is positioned at 8 of wheel rim 5 inwalls.
In sum, the fan blade of axial-flow blower of the present invention adopts the splendid magnesium alloy materials of thermal conductivity that is shaped through die-casting process to make, because having adopted magnesium alloy materials, its significant effect is to make this a part of weight descend 75% especially, thereby the cost of transportation of product also obviously descends.The air quantity of blower fan is increased, and power of motor, electric machine temperature rise and noise reduce, and blower fan prolongation in working life etc. are effect actively.Meanwhile solve preferably, on the wheel rim of fan blade, be provided with two kinds of (increasing the weight of or loss of weight) corrective measures because of more carrying out the consideration that dynamic balancing is regulated behind the conversion materials.
