Description
Technical field
The present invention relates to engine and motor field, and cooling fan is drained more particularly to a kind of motor.
Background technology
In existing engine structure, inverter, motor majority are positioned over engine start side, after machine start, drive cold
But fan air draught cools down, and machine engine, the motor feels hot is the pyrotoxin of machine maximum, it is desirable to which engine, motor are sufficiently cool, draw
Hold up, motor by handle tray suck cooling wind, cooling wind by fan blade rotation throws away, cool down motor, engine again by air passage, increase
The flow of cooling wind is added, the cooling wind in air passage usually first passes through inverter, and cooling wind cools down electricity again after being heated by inverter
Machine and engine, such motor cannot cool down comprehensively, and the cooling effect of engine can be deteriorated, and influence machine efficiency.
In addition, when motor is mounted in engine output terminal, cooling wind is largely thrown away and blows to silencer by cooling fan fan blade, right
Motor cooling deficiency, motor and engine efficiency cannot be exported fully, influence overall performance, it is necessary to improve.
The content of the invention
The invention mainly solves the technical problem of providing a kind of motor to drain cooling fan so that cooling wind directly blows to
Motor, the cooling effect of lifting motor, engine and inverter.
In order to solve the above technical problems, one aspect of the present invention is：A kind of motor drainage cooling wind is provided
Fan, including：Bottom plate, fan blade and guide sleeve, the bottom plate are installed on the rotor of motor and positioned at the front of motor, the inversion
Device is located at the front of bottom plate, and the motor is located at engine side, and annular array is distributed in the surrounding of bottom plate, institute to the fan blade successively
The outside that guide sleeve is arranged concentrically on bottom plate is stated, and the end of fan blade is connected with the inner wall of guide sleeve respectively, the bottom plate
Middle part is provided with axis hole, and the mounting hole that annular array is distributed in axis hole surrounding is provided with the bottom plate.
In a preferred embodiment of the present invention, annular array is distributed in the front edge of bottom plate simultaneously the fan blade successively
Stretch out.
In a preferred embodiment of the present invention, the fan blade respectively to the front of bottom plate be inclined such that cooling wind to
The inner wall of guide sleeve and rear.
In a preferred embodiment of the present invention, the front end of the guide sleeve is provided with a circular cowling.
In a preferred embodiment of the present invention, the circular cowling is integrated with guide sleeve.
In a preferred embodiment of the present invention, the medial surface of the circular cowling is connected with fan blade.
In a preferred embodiment of the present invention, annular array is provided with several ventilation lightening holes on the bottom plate.
The beneficial effects of the invention are as follows：A kind of motor drainage cooling fan that the present invention points out, bottom plate follow motor to carry out
Rotation, during fan air draught, air-flow preferentially by and cool down inverter, ensure that machine uses in hot environment, fan suction is cold
But wind is rotated by fan blade, and centrifugation to periphery guides to motor by guide sleeve by wind is cooled down, the cooling through passing through fan centrifugation pressurization
Wind, sufficiently cool rotor and stator have cooled down the cooling wind after motor and continue through motor front end cover and blow to engine, cooled down
Engine, it is ensured that the cooling effect and work efficiency of cooling inverter, motor and engine, use are more stablized.
