Abstract
The utility model discloses a heat radiating structure of an air blower, which comprises a motor, a bracket, a wind blade, an air blower shell and a wind wheel, wherein the motor is installed on the air blower shell through the bracket, the extension end of the rotating shaft of the motor extends into a cavity inside the air blower shell and is installed and connected with the wind wheel, the wind blade is installed between the motor and the air blower shell and on the rotating shaft, an air hole is drilled on the shell of the motor, a hole is drilled on the lower surface of the wind blade and on the air blower shell, negative pressure is formed inside the motor by utilizing the rotation of the wind blade and the wind wheel, and cold air penetrates through the air hole, a motor winding and the hole under the action of the negative pressure to take the heat of the motor winding into the cavity of the air blower to be discharged. The air has rapid flow and large flow quantity, and the heat radiating effect is quite good.
Description
Technical field:
The utility model relates to a kind of radiating structure of blower.
Background technique:
Present blower, its structure such as Fig. 1, shown in Figure 2, motor 1, support 2, top fan blade 3, blower drum 4, wind wheel 5 and bottom fan blade 7, motor 1 is installed on the blower drum 4 by support 2, the external part of the rotating shaft 6 of motor 1 extend into the cavity of blower drum 4 the insides and couples together with wind wheel 5 installations, between motor 1 and blower drum 4, bottom fan blade 7 is installed in the rotating shaft 6, top fan blade 3 is installed in the other end of rotating shaft 6, on the housing of motor, offer pore 8, around the support 2 radiation hole 9 is set also, but the cavity of blower drum 4 the insides and motor are disconnected.
The entire heat dissipation process is: the top fan blade is delivered to motor windings, bearing with cool air, by bottom fan blade 7 hot air is discharged in the air by around the support 2 radiation hole being set again.The rear and front end and the sidewall of the housing of motor are provided with pore.This radiating structure more complicated, manufacture cost height, and radiating effect is poor can not be effectively in time leads out the heat of motor quickly.
Summary of the invention:
The purpose of this utility model provides a kind of radiating structure of simple in structure, blower that radiating effect is fast.
The purpose of this utility model is achieved by following technical proposals.
A kind of radiating structure of blower, comprise motor, support, fan blade, blower drum and wind wheel, motor is installed on the blower drum by support, the 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, fan blade is installed in the rotating shaft, on the housing of motor, offer pore, wherein: below fan blade, have hole on the blower drum, utilize fan blade and wind wheel to rotate and make motor internal form negative pressure, cool air passes pore under suction function, motor windings and hole take the motor windings heat in the cavity of blower drains.
Seal around the above-mentioned support, the centre is hollow, and fan blade places the support the inside.
The both ends of the surface of the housing of above-mentioned motor all are provided with pore.
Heat radiation pore on the above-mentioned electric machine casing is located on the sidewall away from fan one end.
Between above-mentioned support and the blower drum thermal insulating pad is installed.
Above-mentioned motor is rack-mount by rivet, and support is installed on the blower drum by bolt and nut.
Above-mentioned fan blade is an axial-flow leaf.
The utility model compared with prior art, has following effect: owing to have hole on the blower drum, the cavity of blower is communicated with motor, cool air enters motor internal from the pore on the electric machine casing, utilizes fan blade that the air of motor internal is discharged in the cavity of blower, utilizes the powerful pump drainage gas ability of the wind wheel of blower in the generation of housing the inside again, promptly in the negative pressure of the generation of blower cavity the inside, hot air is drained, and air flows is quick and flow is big, and radiating effect is very good.
