Abstract
The invention relates to a motor stator using liquid cooling. The motor stator includes a stator core and a cooling pipeline. The stator core has an outer peripheral face which is provided with a groove which is intended for mounting the cooling pipeline. The cooling pipeline is mounted with the groove. According to the invention, the pipeline is directly mounted on the outer peripheral face of the stator core, which obviates the need for additionally arranging an engine base and cooling pipelines on the engine base, and heat of the stator can be directly conducted to the cooling pipeline, and the heat is taken away along the flow of a cooling medium within the cooling pipeline, thus completing cooling and increasing effects of heat radiation. At the same time the engine base is eliminated, which saves materials. According to the invention, the stator is genius in design, simple and novel in structure, can rapidly and effectively enable the stator to conduct heat radiation, which improves motor performances and eventually increases efficiency and service life of the motor.
Description
Technical field
The present invention relates to technical field of motors, a kind of liquid cooling motor stator.
Background technology
It is known that the heat dissipating method of common electric machine stator and device, use stator liquid cooling means, fixed
Sub-heat is that support is built with cooling pipe, by cooling pipe to support by stator core conduction of heat
Heat is taken away and is cooled down by the flowing of coolant.Whole chiller includes out frame and cooling pipe.
Common electric machine stator core needs by support due to heat radiation, then is transmitted to cooling pipe by support, and centre has
Repeatedly heat transfer process, so radiating effect need to promote.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the technical problem to be solved is to provide a kind of knot
Structure is simple, the liquid of good heat dissipation effect cooling motor stator.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
A kind of liquid cooling motor stator, including stator core and cooling pipe, the periphery of described stator core
Offering the groove for installing cooling pipe on face, described cooling pipe is arranged in described groove.
The beneficial effects of the present invention is: be different from prior art, the liquid cooling motor stator of the present invention,
Cooling pipe is directly installed on the outer peripheral face of stator core, it is not necessary to additionally arrange the cooling on support and support
Pipeline, the heat of stator can directly be conducted to cooling pipe, by the flowing of cooling medium in cooling pipe
Heat is taken away and cools down, improve radiating effect.Eliminate support simultaneously, save material.The present invention
Designing ingenious, simple in construction is novel, can the most effectively make motor radiating, thus improve motor performance, finally
Improve electric efficiency and life-span.
Accompanying drawing explanation
Fig. 1 show the structural representation of the liquid cooling motor stator of the embodiment of the present invention.

1-stator core；2-cooling pipe.
Detailed description of the invention
By describing the technology contents of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment also
Accompanying drawing is coordinated to be explained.
The design of most critical of the present invention is: be directly installed on the outer peripheral face of stator core by cooling pipe.
Refer to Fig. 1 and Fig. 2, the liquid cooling motor stator that the present invention provides, including stator core 1 He
Cooling pipe 2, the outer peripheral face of described stator core 1 offers the groove for installing cooling pipe 2, institute
State cooling pipe 2 to be arranged in described groove.
Knowable to foregoing description, the beneficial effects of the present invention is: be different from prior art, the liquid of the present invention
Body cooling motor stator, cooling pipe is directly installed on the outer peripheral face of stator core, it is not necessary to additionally arrange machine
Cooling pipe on seat and support, the heat of stator can directly be conducted to cooling pipe, pass through cooling pipe
Heat is taken away and is cooled down by the flowing of interior cooling medium, improves radiating effect.Eliminate support, joint simultaneously
About material.The present invention designs ingenious, and simple in construction is novel, can the most effectively make motor radiating, thus change
Kind motor performance, final raising electric efficiency and life-span.
As a specific embodiment of technique scheme, as depicted in figs. 1 and 2, described groove has multiple,
Multiple grooves are uniformly distributed along the circumference of stator core 1, axial by stator along stator core 1 of described groove
One end of iron core 1 extends to the other end.So, cooling pipe 2 extends to separately from one end of stator core 1
Return from the other end of stator core 1 again behind one end, first in multiple S types after being in turn mounted in each groove
The form that tail connects is arranged on the outer peripheral face of stator core 1, extends cooling path and expands cooling range,
Make motor be dispelled the heat more fully, improve electric efficiency and life-span.
As another specific embodiment of technique scheme, described groove around stator core 1 circumference by
One end of stator core 1 is arranged to the other end helically formula.So, cooling pipe 2 the most helically formula peace
It is contained on the outer peripheral face of stator core 1, extends cooling path and expand cooling range, making motor more be filled
The heat radiation divided, improves electric efficiency and life-span.
Further, described stator core 1 is overrided to form by multiple stator punchings.
Knowable to foregoing description, the beneficial effects of the present invention is: use multiple stator punching to be stacked fixed
Sub-iron core, it is simple to processing.
In sum, the liquid cooling motor stator that the present invention provides, determine owing to cooling pipe is directly installed on
On the outer peripheral face of sub-iron core, therefore without additionally arranging the cooling pipe on support and support, the heat of stator
Can directly be conducted to cooling pipe, by the flowing of cooling medium in cooling pipe heat taken away carry out cold
But, radiating effect is improved.Eliminate support simultaneously, save material.The present invention designs ingenious, structure letter
Single novel, can the most effectively make motor radiating, thus improve motor performance, final raising electric efficiency and longevity
Life.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every profit
