Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of novel cooling asynchronous machine stator.
Background technique
The performance of motor can intuitively be analyzed by the temperature rise of motor each section, and most significantly motor component deformation is serious,
So that the reliability and efficiency of motor have much the reason of substantially reducing, cause motor local pyrexia, such as motor overload etc., this
Great challenge is brought to the cooling performance of motor.The temperature rise of motor not only determines the safety of motor operation, and right
All have a great impact in service life, the efficiency of motor.Common asynchronous moter stator heat is by stator core heat transfer
To base, base is provided with metal cooling-pipe road, takes away heat by the flowing of coolant liquid in cooling pipe and cools down.It is whole
A cooling device includes out frame and cooling pipe.Ordinary motor stator core is needed due to radiating through base, then by machine
Seat is transmitted to cooling pipe, and there is multiple heat transfer process in centre, and the cooling efficiency of metallic conduit reduces, therefore its heat dissipation effect has
It is to be hoisted.
Summary of the invention
The present invention in order to overcome the deficiencies of the prior art, provides that a kind of design is simple, motor stator of good heat dissipation, makes motor
Heat-dissipating pipe of the heat of generation rapidly and in stator groove carries out heat exchange, and the thermal coefficient of graphite is equivalent to 2 to the 3 of copper
Times, 3 to 5 times of aluminium, heat dissipation effect is apparently higher than aluminum material, improves the rate of heat dissipation of motor, while also eliminating base, saves
Material.
Novel cooling asynchronous machine stator provided by the invention, including stator core, graphite radiating pipe, the technical side of use
Case is: the outer peripheral surface of the stator core is equipped with the groove for installing graphite radiating pipe, the graphite radiating pipe installation
In the groove, the heat dissipation effect of the graphite-pipe is apparently higher than aluminum material.The air intake vent and air outlet of the stator groove
Place is respectively equipped with turbofan, can further improve the cooling efficiency of stator groove.
The beneficial effects of the present invention are: being different from the prior art, graphite radiating pipe is directly installed on the periphery of stator core
On face, without the cooling pipe being in addition arranged on base and base, the heat of stator can directly be conducted to graphite radiating pipe, lead to
It crosses the flowing of graphite radiating tube fluid to take away heat and cool down, while the heat dissipation effect of graphite-pipe is apparently higher than aluminum material
Effect, at the same the heat generated from motor operation by the gap of stator groove quickly to external diffusion, and then increase hot-air
Flow, substantially increase radiating efficiency.
The present invention uses graphite radiating pipe, and such heat dissipation effect is apparently higher than the cooling pipe of metal material, while by electricity
The heat that machine operation generates passes through the gap of stator slot quickly to external diffusion, and then increases the flow of hot-air, imitates heat dissipation
Rate greatly improves.On this basis, stator groove is arranged to helical structure, its heat dissipation area, Jin Erzeng can be further increased
It is powered on the radiating efficiency of machine stator groove, while increasing vortex flow fan at the air intake vent of stator groove, air outlet, is vortexed wind
Fan can blow while gathering all directions hot-air to graphite radiating pipe again, increase air velocity, it is recessed to improve stator
The radiating efficiency of slot can greatly improve the service life of motor by such transformation.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of cooling asynchronous machine stator；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is graphite radiating pipe partial schematic diagram.
Specific embodiment:
Referring to FIG. 1 and FIG. 2, novel cooling asynchronous machine stator provided by the invention, including stator core 2 and graphite radiating pipe 1,
The outer peripheral surface of the stator core 2 is equipped with the groove for installing graphite radiating pipe 1, and the graphite radiating pipe 1 is mounted on institute
It states in groove.The groove has multiple, and multiple grooves are uniformly distributed along the circumferential direction of stator core 2, and the groove is along stator core 2
Axial the other end is extended to by one end of stator core 2.In this way, graphite radiating pipe 1 extends to separately from one end of stator core 2
It is returned again from the other end of stator core 2 behind one end, after being in turn mounted in each groove in the form of multiple S types are end to end
It is arranged on the outer peripheral surface of stator core 2, extends cooling path and expands cooling range, motor is made more fully to be radiated,
Improve electric efficiency and service life.The stator groove surround the circumferential of stator core 2
Spiral setting.In this way, equally helically formula is mounted on the outer peripheral surface of stator core 2 graphite radiating pipe 1, extend cooling path
With expansion cooling range, so that motor is more fully radiated, be respectively equipped at the air intake vent and air outlet of the stator groove
Turbofan improves electric efficiency and service life.
