Abstract
The invention discloses a motor cooling structure; a stator iron core of a motor which is wound with a winding is fixedly arranged on a motor shaft through a support; a shell body is rotationally sleeved on the stator iron core wound with the winding and the outer side of the motor shaft; the inside of the support is a closed hollow cavity; cooling liquid is arranged in the hollow cavity; a pipeline, a pump and a radiator are arranged; the pump and the radiator are arranged on the outer side of the shell body; the pump and the radiator are communicated with the hollow cavity of the support through the pipeline to form a circulating loop; the pump supplies power so that the cooling liquid keeps flowing in the circulating loop in a circulating way, the heat brought by the cooling liquid in the support is kept radiated externally through the radiator, the support is quickly cooled to further cool the winding on the outer side of the stator iron core, the motor is not burned down at high temperature even when rotating at high speed, and the service life of the motor is effectively prolonged.
Description
Technical field
The present invention relates to a kind of cooling structure, particularly a kind of motor cooling structure.
Background technology
Motor mainly leans on wind-cooling heat dissipating at present; Heat is loose to the motor outside by the housing absorption back of motor, and this radiating mode dispels the heat slowly, and the high temperature that motor produces in high speed rotating is difficult to distribute fast; Cause motor aging easily, influence the useful life of motor.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of motor cooling structure, this motor cooling structure is simple in structure, cooling is abundant.
The present invention for the technical scheme that solves its technical problem and adopt is: the stator core that a kind of motor cooling structure, motor are tied with winding is fixedly arranged on the motor shaft through support, and the housing rotary seal is sheathed on the stator core that is tied with winding and the outside of motor shaft; For the hollow cavity of sealing, cooling fluid is housed in this hollow cavity in the said support, is provided with pipeline, pump and radiator; Pump and radiator are positioned at hull outside, and pump and radiator are communicated with the hollow cavity of support through pipeline and form a circulation circuit, the heat that produces during machine operation; Pass to cooling fluid, when cooling fluid reached uniform temperature, pump was started working; Cooling fluid flows out in the radiator in the hollow cavity of support through pipeline under the effect of pump, when flowing through radiator heat is distributed; The cooling fluid of heat of loosing is back to the hollow cavity of support again, and so circulation reduces electric machine temperature rise; Motor is worked in a suitable temperature range; Solve the difficult problem of external rotor temperature rise effectively, significantly improved the reliability of motor, made the possibility that creates of high-power wheel hub motor.
As further improvement of the present invention, said pump is an electronic pump, and it takes up room little, and the cooling fluid transmission precisely, and is easy to use.
As further improvement of the present invention; Said pipeline is communicated with the hollow cavity of support and the structure that forms a circulation circuit is: rotating shaft is provided with the water-in and water-out passage; This water-in and water-out passage is positioned at the inboard part of housing and is communicated with the hollow cavity of support respectively, the part that this water-in and water-out passage is positioned at hull outside respectively with pipeline connection.
As further improvement of the present invention, the water-in and water-out passage in the said rotating shaft lays respectively at the hollow cavity two symmetrical sides radially of support, and cooling fluid is fully mobile in the support hollow cavity, makes its cooling fully.
As further improvement of the present invention, said cooling fluid is a kind of in cooling water and the cold oil, can certainly other any coolant, just can as long as play cooling effect.
Useful technique effect of the present invention is: the support of stator core of the present invention is the hollow form structure; Through pipeline it is communicated with the radiator of hull outside; Pump provides power to make circulating that cooling fluid do not stop in circulation circuit; Also just do not stop with the cooling fluid in the support with heat go out through heat sink radiates; Fast stent cools has further been cooled off the winding in the stator core outside,, effectively prolonged the useful life of motor under the situation of high speed rotating even motor also can not burnt by Yin Gaowen.
