Description
Technical field
The utility model is related to electric motors, and in particular to a kind of motor fan cover that thermal diffusivity is strong.
Background technology
Motor (Motor) is a kind of equipment for converting electrical current into mechanical energy.It is that use the power on coil (namely fixed
Sub- winding) it generates rotating excitation field and acts on rotor (such as squirrel-cage is closed aluminium frame) formation electro-magnetic motor force rotation torque.Motor
By using power supply difference to be divided into dc motor and ac motor, the motor in electric system is largely alternating current generator,
It can be synchronous motor either asynchronous machine (motor stator rotational speed of magnetic field does not keep synchronous speed with rotor rotary rpm).It is electronic
Owner will be made of stator and rotor, and the direction of electrified wire movement under force in magnetic field is with current direction and magnetic induction line (magnetic field
Direction) direction is related.Electric motor operation principle is effect of the magnetic field to electric current stress, makes motor rotation.
When in use, motor will produce larger heat, and heat cannot be discharged the damage that can lead to motor, make in time
Stop at production.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of motor wind that thermal diffusivity is strong
Cover.
To achieve the above object, the utility model provides following technical solution：Including rotor and end cap, also set in rotor
There are shaft, shaft to be equipped with active flabellum, be additionally provided with pressurized hole on end cap, the blocking for blocks dust is additionally provided on pressurized hole
Cap is additionally provided with driven flabellum and radiating groove on end cap, and radiating groove is gradually reduced from active flabellum to the direction of driven flabellum, actively
The concave arc direction of flabellum and the concave arc direction of driven flabellum are opposite.
Further, it is additionally provided with guide plate on radiating groove, the angle of guide plate and vertical plane is acute angle.
Further, end cap is equipped with dust-proof cavity, and one end is covered with dust-proof grid in dust-proof cavity, is also set on dust-proof grid
It is useful for that the mounting rod of driven flabellum is installed, driven flabellum is mounted on by bearing on mounting rod.
Further, water conservancy diversion raised line is additionally provided on dust-proof cavity inner wall, water conservancy diversion raised line is in the shape of a spiral.
The deficiencies in the prior art are compared, advantageous effect caused by technical solution provided by the utility model：When in use,
The rotation of active flabellum drives the rotation of driven flabellum because the concave arc direction of active flabellum and the concave arc direction of driven flabellum on the contrary,
Therefore make that air-flow is in whirlwind shape when driven flabellum rotation so that air-flow brushes farther, the heat that can effectively generate motor
Amount is taken away, simultaneously because the rotation of active flabellum, therefore the air pressure in end cap is less than extraneous air pressure, therefore the presence of pressurized hole
Extraneous air is enable to enter cover internal so that more preferable to the heat dissipation effect of motor, blocking cap, therefore can be in coniform
Avoiding dust from entering cover internal out of pressurized hole causes the bad problem of heat dissipation effect to occur, radiating groove from active flabellum to from
The direction of dynamic flabellum is gradually reduced, therefore thermal current can be pressurized during discharge so that thermal current is sprayed more
Far, heating of the thermal current to surrounding motors environment is avoided so that the heat dissipation effect of motor is more preferable.

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
- Fig. 4 is described further the utility model referring to Fig.1.
A kind of motor fan cover that thermal diffusivity is strong, including rotor and end cap 1 are additionally provided with shaft 3 in rotor, are set in shaft 3
There is active flabellum 31, pressurized hole 4 is additionally provided on end cap 1, the blocking cap 41 for blocks dust, end cap 1 are additionally provided on pressurized hole 4
On be additionally provided with driven flabellum 24 and radiating groove 11, radiating groove 11 is gradually reduced from active flabellum 31 to the direction of driven flabellum 24,
The concave arc direction of active flabellum 31 and the concave arc direction of driven flabellum 24 are opposite；When in use, active flabellum 31 rotation drive from
Dynamic flabellum 24 rotates, because the concave arc direction of active flabellum 31 and the concave arc direction of driven flabellum 24 are on the contrary, therefore driven flabellum
Make that air-flow is in whirlwind shape when 24 rotation so that air-flow brushes farther, can effectively take away the heat that motor generates, simultaneously
Due to the rotation of active flabellum 31, the air pressure in end cap 1 is less than extraneous air pressure, therefore the presence of pressurized hole 4 makes outside
Portion's air can enter inside end cap 1 so that more preferable to the heat dissipation effect of motor, blocking cap 41 is in coniform, therefore can be kept away
Exempt from dust and enter cover internal out of pressurized hole the bad problem of heat dissipation effect is caused to occur, radiating groove 11 from active flabellum 31 to
The direction of driven flabellum 24 is gradually reduced, therefore thermal current can be pressurized during discharge so that thermal current was sprayed
It is farther, avoid heating of the thermal current to surrounding motors environment so that the heat dissipation effect of motor is more preferable.
Further, it is additionally provided with guide plate 12 on radiating groove 11, the angle of guide plate 12 and vertical plane is acute angle；Therefore it is oriented to
The presence of plate 12 so that thermal current will not directly parallel blowout, avoid thermal current from blowing to operating personnel, cause operating personnel
Discomfort, while be also avoided that liquid from radiating groove 11 enter end cap 1 in caused by motor damage thing occur.
Further, end cap 1 is equipped with dust-proof cavity 2, and one end is covered with dust-proof grid 23, dust-proof grid in dust-proof cavity 2
The mounting rod 21 for installing driven flabellum 24 is additionally provided on 23, driven flabellum 24 is mounted on by bearing 22 on mounting rod 21,
Therefore when in use, the presence of dust-proof grid 23 allows to blocks dust, and dust is avoided to fall caused by 2 inside of dust-proof cavity
The bad problem of heat dissipation effect occurs.
Further, 2 inner wall of dust-proof cavity is additionally provided with water conservancy diversion raised line, and water conservancy diversion raised line in the shape of a spiral, therefore can make spiral
The air-flow of shape is further reinforced so that wind pressure bigger, it is more preferable to the heat dissipation effect of motor.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
