Abstract
The utility model discloses an electric motor liquid cooling structure, which is characterized in that the outer side of the stator core of an electric motor is wound with a winding, the stator core wound with the winding is fixedly arranged on a motor shaft, two ends of a casing of the electric motor are axially and fixedly provided with end covers in a sealing way, the whole motive seal formed by the end cover and the casing is sleeved on the outer side of the stator core wound with the winding, and the casing, the end cover, the motor shaft and the stator core wound with the winding form a sealed annular space in which cooling liquid is arranged; when the electric motor works, under the combined action of the rotation of the casing and the end cover, and the agitation and centrifugal force of the convex rib on the inner side of the end cover, the cooling liquid moves in the sealed annular space, the cooling liquid brings away the heat of the winding and the stator core when flowing through the surfaces of the winding and the stator core so as to make the heat be quickly conducted to the casing of the motor and the end cover, thereby, the fast cooling is realized, the motor can not be burn out due to the high temperature under the condition of high speed revolution or high power, and the service life of the motor is effectively prolonged.
Description
Technical field
The utility model relates to a kind of motor cooling structure, particularly a kind of motor liquid cooling structure.
Background technology
The heat of motor windings generation at present passes to the housing and the end cap of motor by radiation mode, absorbed the diffusing motor outside of arriving, back by housing and end cap, pass through wind-cooling heat dissipating, this radiating mode heat radiation is slow, the heat that motor produces when work 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 utility model provides a kind of motor liquid cooling structure, and this motor liquid cooling is simple in structure, heat transferred fast, cooling is abundant.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of motor liquid cooling structure, the stator core outer felt of motor is wound with winding, the stator core that is tied with winding is fixedly arranged on the motor shaft by support, the housing shaft of motor is to the sealed at both ends end cap that is installed with, the whole movable sealing sleeve that end cap and housing form is located at the outside of the stator core that is tied with winding, described housing, end cap, motor shaft and be tied with the annulus that forms a sealing between the stator core of winding, cooling fluid is placed in this annulus, during machine operation, because the rotation of housing and end cap, cooling fluid annulus in sealing under the acting in conjunction of the stirring of the inboard convex tendon of end cap and centrifugal force produces motion, when cooling fluid is flowed through winding and stator core surface, heat on winding and the stator core is taken away, and heat is distributed fast by housing and end cap, guarantee that winding can effectively not prolong the useful life of motor because of high temperature ageing.
As further improvement of the utility model, described end cap madial wall is provided with the some convex tendons from the radiation of middle mind-set periphery, cooling fluid is produced flowed, and can increase radiating surface again, further accelerates the motor cooling.
As further improvement of the utility model, described convex tendon is a linear pattern.
As further improvement of the utility model, described convex tendon is and end cap cylindrical tangent line off plumb angled straight lines type.
As further improvement of the utility model, described convex tendon is an arc line type.
As further improvement of the utility model, the convex tendon of the end cap inboard at described housing two ends is the identical convex tendon of incline direction.
As further improvement of the utility model, the convex tendon of the end cap inboard at described housing two ends is the opposite convex tendon of incline direction, be between rightabout convex tendon at the two ends end cap when this of convex tendon kind of distribution mode is thrown away cooling fluid and form eddy current, mobile cooling pendular ring is further accelerated the cooling of motor.
As further improvement of the utility model, described end cap lateral wall is provided with the heat radiation wing of convex rib structure, further accelerates motor radiating.
As further improvement of the utility model, described cooling fluid is a cold oil, and other any cooling fluids can play cooling effect and also can certainly.
Useful technique effect of the present utility model is: the utility model passes through at electric machine casing, end cap and motor shaft and be tied with the annulus that forms sealing between the stator core of winding, in this annulus, add cooling fluid, during machine operation, because the rotation of housing and end cap, under the stirring of the inboard convex tendon of end cap and the acting in conjunction of centrifugal force, cooling fluid produces motion at the annulus of sealing, when cooling fluid is flowed through winding and stator core surface, heat on winding and the stator core is taken away, heat is transmitted on the housing and end cap of motor fast, realize quick heat radiating, even motor also can not burnt by Yin Gaowen under the situation of high speed rotating or high power work, has effectively prolonged the useful life of motor.
