[0002] The high-power semi-direct-drive permanent magnet motor used in the oil pumping unit has the characteristics of low speed and high power operation. Due to space limitations, the internal space of the motor is extremely compact.

[0003] The permanent magnet excitation used in the rotor of a semi-direct-drive permanent magnet motor lacks inherent cooling capabilities. In practical applications, this prevents the high heat energy generated during motor operation from being dissipated. This directly results in aging of the electromagnetic coil insulation and demagnetization of the magnets, significantly reducing the motor's output torque and even causing coil burnout. This restricts the efficiency of high-power semi-direct-drive permanent magnet motors and urgently requires solutions to extend their service life.

The vortex fan rotor frame 15 is sleeved on the transmission shaft 17, and a plurality of vortex fan blades 16 are provided on the circumference of the vortex fan rotor frame 15.

[0022] In actual application, the output shaft drives the transmission shaft 17 to rotate, and the air from the multiple vortex fan blades 16 is squeezed toward the edge of the vortex fan rotor frame 15 by centrifugal force, and the vortex fan rotor frame 15 generates air flow by rotating.

The turbulence in the form of auxiliary airflow is utilized to enhance the rotation speed of the air flow, thereby improving the cooling effect of the vortex refrigerator 04. The interior of the vortex tube 20 is a cold air channel 24.

[0026] In actual application, air enters through the wire 25, rotates at high speed through the open groove 26, and enters the vortex cavity 21 through the vortex tube 20. The vortex tube 20 introduces auxiliary airflow through the circular hole 27, and the auxiliary airflow enters the vortex cavity 21. The vortex cavity 21 expands the gas volume and absorbs heat. A vortex is formed inside the vortex tube 20, and the vortex is separated into hot air flow and cold air flow through high-speed rotation. Further, the vortex is separated into two flow directions with opposite temperatures during the high-speed rotation. The vortex is separated into hot air flow and cold air flow through high-speed rotation. The air in the outer circle is concentrated to the hot end of the vortex tube 04 to become a hot air flow, which is discharged from the hot air outlet 18. The air flow in the center part is the cold air flow, which is discharged through the cold air channel 24 at the cold end of the vortex tube.

[0027] This invention, as a key node technology for supporting high-power semi-direct-drive permanent magnet motors for oil pumping units, represents a significant technological breakthrough. Based on eddy current refrigeration technology, it provides an auxiliary cooling device for semi-direct-drive permanent magnet motors, overcoming the insufficient cooling problem of semi-direct-drive permanent magnet motors in existing technology systems. The following describes in detail the working principle of this eddy current heat dissipation device for semi-direct-drive motors: In this embodiment, the semi-direct drive motor, referred to as the electric motor, starts running. In addition to providing power output to the inner reduction gearbox, the motor output shaft also provides power to the outer transmission shaft 17. The transmission shaft 17 drives the first vortex fan 01 to rotate, driving the vortex fan rotor frame 15 and the vortex fan blades 16 to rotate. The air between the vortex fan blades 16 is subjected to the centrifugal force, and the air is sucked in from the inlet filter 14 on the vortex fan side plate 11, and squeezed and moved toward the edge of the vortex fan rotor frame 15. The air flow generated by its rotation enters the channel of the tee pipe 05, and enters the vortex cooler 04 along the air inlet pipe 06; after encountering the multiple groups of inclined opening grooves 26 on the edge of the vortex tube 20, it enters the vortex cavity 21. The open slot 26 causes the main airflow to rotate at high speed, and the auxiliary airflow introduced by the vortex tube 20 through the circular hole 27 further enhances the rotation of the main airflow. After the rotating air flow enters the vortex chamber 21, the gas volume will expand and absorb heat, and then a vortex will be formed in the vortex tube 04. The vortex is separated into two flow directions with opposite temperatures during the high-speed rotation process. The air in the outer circle is concentrated to the hot end of the vortex tube 04 to become a hot air flow, which is discharged out of the motor through the hot air outlet 18. In addition, the cold air flow in the center part is discharged through the cold air outlet 24 at the cold end of the vortex tube and enters the refrigeration pipe 07. The coils of the refrigeration pipe 07 are arranged along the lateral area inside the motor, and after fully absorbing the heat inside the motor, it is discharged out of the motor through the exhaust port 19.

[0028] In practical applications, a closed-loop eddy current cooling device solves the problem of high-density heat dissipation inside narrow semi-direct-drive permanent magnet motors, avoiding the problem of temperature difference inside the motor that exists in other peripheral heat dissipation methods; the hot and cold air circulated in the eddy current cooling device pipelines does not enter the interior of the motor, and will not cause dust accumulation to affect equipment safety; due to the relative closedness and high temperature inside the motor, the cooling pipes of the eddy current cooling device cannot condense moisture, and will not affect the insulation level inside the motor; the circulating air of the eddy current cooling device is not affected by dust, rain or snow in the air, and does not require maintenance; the heat dissipation requirements brought about by different seasons and different power loads can be solved by replacing the headless screws with different apertures in the current limiting screw.

[0029] In addition, since the speed of the semi-direct-drive permanent magnet motor is generally low, if the load or heat generation of the motor is too large, the air volume and air pressure of the first vortex fan 01 will not meet the heat dissipation requirements of the motor. In principle, the capacity of the first vortex fan 01 can be increased or the power of the vortex fan can be increased by changing the speed, but in most cases the outer space of the motor is limited, so a double vortex fan heat dissipation device can be used to flexibly solve the problem.

[0030] Figure 9 This is a structural diagram of a dual-eddy current heat dissipation device for a semi-direct drive motor according to an embodiment of the present invention. Figure 9As shown, a second turbine fan 28 with the same specifications as the first vortex fan 01 is newly added. The second turbine fan 28 includes a plurality of second vortex fan blades 29. In addition to being fixed by conventional mechanical means, it runs in parallel with the drive shaft 17 of the first vortex fan 01 through a coupling. The inlet filter 14 on the side panel 11 of the first vortex fan is removed and reinstalled at the corresponding position of the second turbine fan 28. The left and right air outlets of the second turbine fan 28 are connected to an additional three-way pipe 30. The additional three-way pipe 30 is connected to the three-way pipe plug 12 interface through a connecting pipe 31. The three-way pipe plug 12 is reinstalled to the corresponding position of the additional three-way pipe 30. By running the vortex fans in parallel, the dual vortex fan combination can greatly increase the air flow and wind pressure entering the vortex cooler 04, further improving the heat dissipation capacity of the motor.

[0031] In practical applications, the parallel combination of twin-vortex fans is an extended application of the present invention. Based on common sense, professional and technical personnel can realize the methods of split-series booster combination of fans, integrated multi-combination of fans, split-parallel multi-combination of fans, etc. to increase the air flow and pressure, but they all fall within the protection scope listed in the present invention.

[0032] The disc-type semi-direct-drive motor provided by the present invention is equipped with a vortex tube heat dissipation device. Compressed air is provided by a vortex fan on the outer shaft of the motor, which is connected to the vortex refrigeration device through a pipeline. Heat exchange pipelines are arranged on the side walls inside the motor to absorb heat inside the motor, thereby reducing the ambient temperature and further overcoming the defect of insufficient cooling of the motor. It can not only improve the problem of the motor being unable to dissipate heat when running at high temperature, but also effectively realize synchronous vortex refrigeration auxiliary cooling.

[0033] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
