(3) model utility content:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and the weight of motor can be evenly distributed on the blower drum, and structure is firm not yielding, the blower fan structure that noise is less.
The utility model is to realize by following technological scheme: a kind of blower fan structure, comprise motor, support, blower drum, wind wheel and heat radiation fan blade, motor is installed on the blower drum by support, the top external part of machine shaft extend into the cavity of blower drum the inside and couples together with the wind wheel installation, between motor and blower drum, the heat radiation fan blade is installed on the machine shaft, pore is set on the electric machine casing, wherein: described support forms annular sidewall, the annular sidewall the inside forms cavity, annular sidewall is left air outlet hole, air outlet hole is communicated with cavity, and described heat radiation fan blade places the cavity the inside.
The bottom surface is extended on above-mentioned annular sidewall top toward in, support couples together by the end face of bottom surface and electric machine casing, and the annular sidewall bottom is extended flange outward, and support couples together by flange and blower drum.
Above-mentioned flange is a surface plate.Above-mentioned support is bowl-shape.
The vibration damping thermal insulating pad is installed between above-mentioned flange and the blower drum.
Above-mentioned machine shaft afterbody stretches out electric machine casing and the top fan blade is installed.
Above-mentioned motor is rack-mount by rivet, and support is installed on the blower drum by rivet.
The utility model compared with prior art, following advantage is arranged: 1) support forms annular sidewall, the bottom surface is extended on the annular sidewall top toward in, support couples together by the end face of bottom surface and electric machine casing, and the annular sidewall bottom is extended flange outward, support couples together by flange and blower drum, the junction surface of support is big, and stressed even, it is firm to connect, vibration and noise are little, not yielding; 2) the top fan blade is installed at the electric machine casing top, the annular sidewall the inside forms cavity the heat radiation fan blade is installed, and annular sidewall on leave air outlet hole, form stable air-flow path, cool air is entered by the pore at electric machine casing top, pore from the electric machine casing sidewall after the part air heat exchange comes out, all the other cool airs are drawn onto the cavity of annular sidewall by the fan blade that dispels the heat, cool air fully contacts the absorption heat with the rotor of motor, leaving air outlet hole by annular sidewall at last discharges, rapid heat dissipation, good heat dissipation effect; 3) the vibration damping thermal insulating pad is installed between flange and the blower drum, the heat that can reduce vibration and blower is difficult to be delivered to support and motor, guarantees motor proper functioning at a certain temperature.
