Description

Technical Field

[0001] The utility model relates to the technical field of motor equipment, in particular to a water cooling structure of a motor and a motor stator. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils to generate a rotating magnetic field, which acts on the rotor to generate magneto-electrodynamic torque. The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, stator windings, and the frame. The stator's primary function is to generate a rotating magnetic field, while the rotor's primary function is to be cut by magnetic lines of force in the rotating magnetic field, generating current.

[0003] Upon investigation, the publication (announcement) number: CN202221085356.6 discloses a stator core with a cooling structure. This technology discloses "including a stator core body, the stator core body including a tooth portion and a yoke portion, the stator core body is provided with a water cooling structure on the outer periphery of its yoke portion, the water cooling structure includes an inner layer, an outer layer and a water channel provided between the inner layer and the outer layer, the inner layer is provided with a positioning stop for fixing the water cooling structure to the stator core body, and the outer layer is used to connect to the outer shell; the stator core body is provided with ventilation holes on its teeth and / or yoke portion, and the ventilation holes are through holes that pass through the upper and lower ends of the teeth or yoke portion. The cooling structure of this motor of the utility model, which is composed of two parts: ventilation cooling of the stator core and water channel cooling of the stator core outer shell, can improve the operating performance of the motor and has the advantages of high reliability, strong versatility, and compact structure."

[0004] When the existing water-cooling structure of the motor and motor stator is in use, the cooling water can dissipate heat inside the motor through continuous circulation. However, when the motor is operated for a long time, the internal temperature of the motor transfers heat with the cooling water, and the circulating cooling water cannot discharge the heat out of the water-cooling pipe in time, which can easily cause the water-cooling effect of the stator to deteriorate and affect the service life of the motor.

[0005] In order to solve the above problems, the present application proposes a water cooling structure for a motor and a motor stator. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1-Figure 5 As shown;

[0029] A water-cooling structure for a motor and a motor stator comprises a base 1.

[0030] In this embodiment: after investigation, the public (announcement) number: CN202221085356.6 discloses a stator core with a cooling structure. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "the existing water-cooling structure of the motor and the motor stator can dissipate heat inside the motor by circulating the cooling water continuously when in use. However, after the motor has been operating for a long time, the internal temperature thereof realizes heat transfer with the cooling water, and the circulating cooling water cannot discharge the heat out of the water-cooling pipe in time, which easily causes the water-cooling effect of the stator to deteriorate, affecting the service life of the motor". In terms of combined use, this problem is obviously a problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a water-cooling component 5 and a dust removal component 6 are added to this application document;

[0031] Specifically: a motor body 2 is fixedly provided on the top of the base 1, a plurality of equidistantly arranged heat dissipating fins 3 are fixedly provided on the surface of the motor body 2, a stator body 4 is fixedly provided in the middle of the interior of the motor body 2, a water cooling component 5 is provided on the surface of the stator body 4, and a dust removal component 6 is provided on one side of the top of the base 1.

[0032] like Figures 1 to 5 As shown:

[0033] In combination with the above content: the water cooling assembly 5 includes a plurality of heat conducting rods 51, a water cooling pipe 52, a heat conducting frame 53, a dustproof net 54 and a plurality of heat dissipation fans 55. The plurality of heat conducting rods 51 are fixedly arranged on the inner wall of the stator body 4 at equal distances. The water cooling pipe 52 is fixedly arranged between the plurality of heat conducting rods 51. The heat conducting frame 53 is fixedly arranged at the middle part of the top of the stator body 4. The dustproof net 54 is fixedly arranged at the top of the heat conducting frame 53. The top of the heat conducting frame 53 is fixedly provided with a plurality of heat dissipation fans 55.

[0034] A circulation pump 9 is fixedly provided on one side of the front of the base 1 . The liquid suction pipe and liquid discharge pipe of the circulation pump 9 are respectively connected to the base 1 and the water cooling pipe 52 . A cooling fin 10 is fixedly provided on the bottom end of the base 1 .

[0035] In this embodiment: the cooling water in the base 1 is injected into the water-cooling pipe 52 through the liquid outlet pipe through the liquid suction pipe of the circulation pump 9. Since the water-cooling pipe 52 is arranged between the plurality of heat-conducting rods 51 and can flow back and forth through the inner walls of the plurality of heat-conducting rods 51, the heat can be absorbed by the plurality of heat-conducting rods 51, and then absorbed by the circulating cooling water, and finally flows back into the base 1 for circulation and cooling. When the heat inside the motor body 2 is too high, the plurality of cooling fans 55 blow the hot air inside the motor body 2 to the outside through the dustproof net 54, further improving the heat dissipation efficiency inside the motor body 2. At the same time, the heat absorption surface of the refrigeration plate 10 absorbs the heat of the cooling water in the base 1, thereby enabling the motor body 2 to maintain a good heat dissipation effect.

[0036] In an optional embodiment, the dust removal assembly 6 includes a support plate 61, an electric push rod 62, a movable rod 63, and two cleaning rings 64. The support plate 61 is fixedly arranged on one side of the top of the base 1. The electric push rod 62 is fixedly arranged on one side of the top of the support plate 61. The push rod of the electric push rod 62 is fixedly connected to the movable rod 63. The two cleaning rings 64 are respectively sleeved on the surfaces of the plurality of heat dissipating fins 3. One end of the movable rod 63 is fixedly connected to one of the cleaning rings 64.

[0037] A connecting rod 7 is fixed between the two cleaning rings 64 . A plurality of guide grooves 8 are formed on the surfaces of the two cleaning rings 64 . The plurality of guide grooves 8 are slidably connected to the plurality of heat dissipation fins 3 .

[0038] In this embodiment, the two cleaning rings 64 are moved horizontally by the push rod of the electric push rod 62 , and at the same time, the guide grooves 8 facilitate sliding along the surfaces of the plurality of heat dissipation fins 3 , thereby cleaning the plurality of heat dissipation fins 3 .

[0039] In an optional embodiment, a noise reduction plate 11 is fixedly provided on one side of the interior of the motor body 2, a plurality of noise reduction holes 12 are opened on the surface of the noise reduction plate 11, and the inner walls of the plurality of noise reduction holes 12 are filled with sound-absorbing cotton 13;

[0040] A bottom cover 14 is fixedly provided on one side of the motor body 2 , and a sound insulation sponge layer 15 is fixedly provided on the inner wall of the bottom cover 14 .

[0041] In this embodiment, the noise generated by the motor body 2 during operation can be effectively reduced by a plurality of sound-absorbing cottons 13 and sound-insulating sponge layers 15 .

[0042] In an optional embodiment: a temperature controller 16 is fixedly provided on one side of the front of the base 1, a detection probe of the temperature controller 16 is fixedly set inside the base 1, and several cooling fans 55 and cooling fins 10 are electrically connected to the power supply through the temperature controller 16.

[0043] The working principle and use process of the present invention are as follows: first, the temperature detection range of the temperature controller 16 is set according to the appropriate temperature environment of the motor body 2. When the cooling water temperature in the base 1 is within the detection range of the temperature controller 16, the cooling water in the base 1 is injected into the water-cooling pipe 52 through the liquid outlet pipe via the liquid suction pipe of the circulation pump 9. Since the water-cooling pipe 52 is arranged between a plurality of heat-conducting rods 51 and can flow back and forth through the inner walls of a plurality of heat-conducting rods 51, the heat can be absorbed by the plurality of heat-conducting rods 51, and then absorbed by the circulating cooling water, and finally re-flowed into the base 1 for circulation and cooling. When the cooling water temperature in the base 1 exceeds the detection range of the temperature controller 16, the temperature controller 16 controls the operation of a plurality of cooling fans 55 and refrigeration plates 10, and a plurality of cooling fans 55 and refrigeration plates 10 are operated. The thermal fan 55 blows the hot air inside the motor body 2 to the outside through the dustproof net 54, further improving the heat dissipation efficiency inside the motor body 2. At the same time, the heat absorption surface of the refrigeration plate 10 absorbs the heat of the cooling water in the base 1, and then discharges the heat through its heat dissipation surface, so that the cooling water after absorbing the heat can be quickly cooled, so that the motor body 2 can maintain a good heat dissipation effect. When there is excessive dust on the surface of several cooling fins 3, the two cleaning rings 64 are moved horizontally by the push rod of the electric push rod 62. At the same time, several guide grooves 8 facilitate sliding along the surface of several cooling fins 3, so that several cooling fins 3 can be cleaned. At the same time, during the operation of the motor body 2, the noise generated by it can be effectively reduced by several silencer cottons 13 and sound insulation sponge layers 15.
