Abstract
The invention discloses a modified axial flow fan. The modified axial flow fan comprises a support and a motor. The motor is of a structure that a rotor is arranged outside, a stator is arranged inside, wherein the stator is fixedly installed on the support, the rotor is arranged on the rotor in a rotating and sleeved mode, fan blades are installed on the outer surface of the rotor, a rotor winding is arranged on the rotor, a stator winding is arranged on the stator, the stator is hollow, the two ends of the stator are communicated with outside air, the rotor winding and the stator winding are both arranged between the rotor and the stator, a bearing is arranged between the rotor and the stator in a sleeved mode, a positioning snap spring is arranged on the inner side of the bearing, a seal ring is arranged on the outer side of the bearing, and the seal ring, the stator and the rotor are in interference fit. According to the modified axial flow fan, the stator is hollow, and the two ends of the stator are communicated with the outside air so that the air can flow inside the stator to take away heat generated by the motor, therefore, the overall weight of the modified axial flow fan is reduced, the heat dissipation performance of the modified axial flow fan is enhanced, and the service life is prolonged; the positioning snap spring not only prevents the rotor winding from moving but also limits the bearing; the seal ring, the stator and the rotor are in interference fit, so that dust and impurities are effectively prevented from entering the modified axial flow fan.
Description
Technical field
The present invention relates to a kind of blower fan, particularly a kind of improved axial-flow blower.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure.By the mechanical energy of rotation is converted to gas pressure energy and kinetic energy, and a kind of machinery that gas is transferred out.And the focus that the height of the size of the power consumption of blower fan, efficient is not to use the person to pay close attention to always.Traditional blower fan has generally that weight is big, poor radiation, sealing are poor, the shortcoming that working life is short.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, provide after a kind of improve in light weight, thermal diffusivity good, sealing is strong, the axial-flow blower of long service life.
Technological scheme of the present invention is achieved in that
A kind of improved axial-flow blower, comprise bearing, motor, described motor is external rotor inner stator structure, stator is fixedly mounted on the bearing, the rotor rotating sleeve is located on the stator, at rotor outer surface fan blade is installed, at rotor, be respectively equipped with the rotor winding on the stator, staor winding, stator hollow and two ends communicate with ambient air, the rotor winding, staor winding all is arranged in the space between rotor and the stator, is arranged with two bearings between rotor and stator, is provided with the location jump ring in the bearing inboard, be provided with seal ring, described seal ring and stator in the bearing outside, the rotor interference fit.
Adopted working principle of the present invention and the beneficial effect of technique scheme to be:
Axial-flow blower of the present invention adopts external rotor inner stator structure, and the bearing next door between stator rotor is provided with the location jump ring, both can prevent that the rotor winding from moving, and can carry out spacing to bearing again; In the bearing arranged outside seal ring, seal ring and stator, rotor interference fit can prevent effectively that dust impurity from entering; The most important thing is that two ends and ambient air that the present invention's stator is set to hollow and hollow keep connecting, and air can be flowed in stator, the heat that motor produces is taken away, both reduce the overall weight of blower fan, strengthened its thermal diffusivity again, prolonged working life.
Description of drawings
Fig. 1 is the cross sectional representation of blower fan of the present invention;
Embodiment
