Description

Technical Field

[0001] The present invention belongs to the technical field of motor heat dissipation, and more specifically, relates to a motor with multi-structure coordinated heat dissipation. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. Its working principle is based on electromagnetic induction and electromagnetic force. By passing current through the stator winding, a rotating magnetic field is generated. This magnetic field interacts with the current in the rotor, thereby generating a torque that causes the rotor to rotate. There are many types of electric motors, the most common ones are DC motors and AC motors. The power supply of DC motors is usually DC power, and their speed regulation performance is good, but the structure is relatively complex. AC motors include asynchronous motors and synchronous motors. Asynchronous motors have a simple structure, reliable operation, and low cost, and are widely used in various industrial and civil occasions; synchronous motors have the characteristics of constant speed and adjustable power factor, and are often used in large-scale mechanical equipment and power systems.

[0003] When existing motors are cooled, a guide fan is usually added to the output to blow the air from the filter cover toward the motor housing for heat exchange. However, since the heat inside the motor is indirectly dissipated by conducting it to the housing, rather than directly dissipating the heat inside the motor, the heat dissipation efficiency is low, the practicality is insufficient, and needs to be improved.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an electric motor with multiple structures and coordinated heat dissipation is provided, in order to achieve a purpose with greater practical value. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an electric motor with multiple structures for coordinated heat dissipation to solve the above problems.

[0007] A plurality of heat dissipation mechanisms are installed on the inner side wall of the heat-conducting inner shell;

[0008] The heat dissipation mechanism includes a rotating shaft, each of the rotating shafts is partially exposed outside the first through slot, each of the rotating shafts is partially exposed inside the first through slot, a gear is fixedly mounted on the circumferential surface of each rotating shaft, each of the gears is located outside the first through slot, a fan blade assembly is fixedly mounted on the circumferential surface of each rotating shaft, each of the fan blade assembly is located inside the heat conduction inner shell, a drainage fan blade is fixedly mounted on the circumferential surface of the output shaft body, and an annular rack is fixedly mounted on the side wall of the drainage fan blade.

[0009] Preferably, a first through slot is provided inside the heat dissipation outer shell and the heat conduction inner shell, a plurality of second through slots are provided on the side wall of the motor body, a pipe is fixedly installed between two of the first through slots, a filter core is provided inside the pipe, and a one-way flow ventilation valve is provided inside each of the second through slots.

[0010] Preferably, each of the one-way flow ventilation valves can blow the air inside the heat conduction inner shell out of the heat conduction inner shell, a filter air cover is provided on the side wall of the motor body, the filter air cover is fixedly installed with the heat conduction inner shell, each of the gears is located between the filter air cover and the heat conduction inner shell, and the drainage fan blades are located between the filter air cover and the heat conduction inner shell.

[0011] Preferably, the annular rack is installed in meshing engagement with the gear, a slide groove is provided inside the filter air cover, the end portion of the output shaft body close to the annular rack extends out of the filter air cover, the output shaft body is rotatably installed with the filter air cover, and a scraper is fixedly installed on the circumferential surface of the output shaft body.

[0012] Preferably, the scraper is located outside the filter air cover, the scraper is in contact with the surface of the filter air cover, and a slider is slidably installed inside the slide groove.

[0013] Preferably, the scraper strip is fixedly mounted to the slider, an electromagnetic induction unit assembly is provided inside the heat conduction inner shell, the electromagnetic induction unit assembly is adapted to the output shaft body, and a gap is left inside the electromagnetic induction unit assembly.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, an annular rack is provided on the drainage fan blade to generate a radial force on the gear to indirectly drive the rotation of the rotating shaft, so that multiple fan blade assemblies can be rotated synchronously. Compared with directly installing the fan blades inside the output shaft body, the provision of multiple fan blade assemblies can make the heat dissipation more uniform and avoid the occurrence of local overheating. At the same time, the use of the annular rack to drive the gear to rotate can increase the speed and wind pressure of the fan blade assembly, thereby improving the heat dissipation effect. The higher wind pressure can help the air better penetrate the heat dissipation channel inside the motor, take the heat away from the inside of the motor body, and further improve the heat dissipation rate.

[0016] In the present invention, by providing a heat dissipation mechanism, when the output shaft body rotates, the activation of the output shaft body will drive the guide blades to rotate, and then drive the annular rack to rotate, so that the annular rack and the gear on the rotating shaft produce meshing transmission, so that the gear generates a radial force synchronized with the rotation of the annular rack and rotates together, and then each gear drives the rotating shaft to rotate, so that the fan blade assembly inside the heat conduction inner shell is blown toward one side of the one-way flow ventilation valve, so that the heat can be blown out through the one-way flow ventilation valve in the second through groove, and then the heat dissipation inside the motor body can be completed, and the heat dissipation rate can be further improved;

[0017] In the present invention, a scraper is provided on the output shaft body, so that when the output shaft body rotates, the movement of the output shaft body will generate a radial force on the scraper. This radial force causes the scraper to scrape the surface of the filter cover, thereby effectively cleaning the impurities remaining on the surface of the filter cover, preventing the impurities from clogging the air inlet of the filter cover, resulting in a reduction in the air volume taken in by the drainage fan blades, and further affecting the heat dissipation rate of the entire heat dissipation system.

[0018] In the present invention, by providing a sliding groove on the outside of the filter cover, when the output shaft body drives the scraper to rotate, the scraper will simultaneously generate a radial force to drive the slider to slide inside the sliding groove of the filter cover, thereby providing additional support and guidance, and improving stability;

[0019] In the present invention, by arranging a pipe between the heat dissipation outer shell and the heat conduction inner shell, and arranging a filter inner core inside the pipe, it is possible to prevent impurities in the air taken in from the pipe from entering the heat conduction inner shell and affecting the operation of the electromagnetic induction unit assembly. At the same time, by providing a plurality of second through grooves on the side wall of the heat conduction inner shell away from the annular rack, and providing a one-way flow ventilation valve inside each second through groove, air convection can be carried out inside the heat conduction inner shell when the fan blade assembly is in operation, which is beneficial to heat dissipation. At the same time, since the hot air is discharged through the one-way flow ventilation valve, the reduction in heat dissipation efficiency caused by the backflow of hot air is avoided, thereby further improving reliability.

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] See also Figure 1-Figure 7 The present invention provides a motor with multiple structures for heat dissipation, including a motor body 11. The motor body 11 is provided with a heat dissipation outer shell 12 and a heat conduction inner shell 13 on its surface. The heat conduction inner shell 13 is located inside the heat dissipation outer shell 12. The motor body 11 and the heat dissipation outer shell 12 are fixedly installed. The heat conduction inner shell 13 is provided with an output shaft body 15 inside.

[0030] A plurality of heat dissipation mechanisms are installed on the inner side wall of the heat-conducting inner shell 13;

[0031] The heat dissipation mechanism includes a rotating shaft 22, each rotating shaft 22 is partially exposed outside the first through slot 16, each rotating shaft 22 is partially exposed inside the first through slot 16, a gear 23 is fixedly installed on the circumferential surface of each rotating shaft 22, each gear 23 is located outside the first through slot 16, a fan blade assembly 24 is fixedly installed on the circumferential surface of each rotating shaft 22, each fan blade assembly 24 is located inside the heat conduction inner shell 13, and a drainage fan blade 25 is fixedly installed on the circumferential surface of the output shaft body 15. An annular rack 26 is fixedly installed on the side wall of the drainage fan blade 25. By setting the heat dissipation mechanism, when the output shaft body 15 starts to rotate, the radial force generated will be transmitted to the drainage fan blade 25, causing it to start rotating synchronously. Such rotation further drives the rotation of the annular rack 26, so that the annular The rack 26 begins to interact with the gear 23 on the rotating shaft 22, forming an engaged transmission. During this process, the gear 23 will generate a radial force consistent with the direction of the annular rack 26, and under the action of this force, the gear 23 and the annular rack 26 rotate together, so that each gear 23 can effectively drive the rotating shaft 22 to rotate, thereby causing the fan blade assembly 24 inside the heat conduction inner shell 13 to generate a flow of air blowing toward the side of the one-way flow ventilation valve 21. This flow of air passes through the one-way flow ventilation valve 21 in the second through groove 17, effectively blowing out the heat, thereby realizing the heat dissipation inside the motor body 11. This design not only improves the heat dissipation efficiency, but also greatly improves the heat dissipation rate, providing a strong guarantee for the stable operation of the motor body 11.

[0032] A first through slot 16 is provided inside the heat dissipation shell 12 and the heat conduction inner shell 13, and a plurality of second through slots 17 are provided on the side wall of the motor body 11. A pipe 18 is fixedly installed between the two first through slots 16, and a filter core 19 is provided inside the pipe 18. A one-way flow ventilation valve 21 is provided inside each second through slot 17. Each one-way flow ventilation valve 21 can blow the air inside the heat conduction inner shell 13 out of the heat conduction inner shell 13. A filter cover 14 is provided on the side wall of the motor body 11. The filter cover 14 is fixedly installed with the heat conduction inner shell 13. Each gear 23 is located between the filter cover 14 and the heat conduction inner shell 13, and the guide fan blades 25 are located between the filter cover 14 and the heat conduction inner shell 13. In order to improve the heat exchange efficiency and optimize the performance of the heat conduction system, a plurality of second through slots 17 are provided on the side wall of the heat conduction inner shell 13 away from the annular rack 26. These second through slots 17 The setting not only increases the air flow path, but also enables the fan blade assembly 24 to promote effective air convection inside the heat conduction inner shell 13 when rotating. This convection greatly promotes the dispersion and transfer of heat, thereby significantly improving the heat dissipation performance. At the same time, by installing a one-way flow ventilation valve 21 inside each second through groove 17, these one-way flow ventilation valves 21 ensure that the hot air can only flow in one direction when discharged, and no reverse reflux will occur, effectively avoiding the problem of reduced heat dissipation efficiency caused by hot air reflux. During the heat exchange process, the hot air can be smoothly discharged from the heat source area, ensuring the efficiency and continuity of the heat dissipation process, thereby not only improving the heat exchange reliability of the system, but also optimizing the overall thermal management, so that the equipment can maintain a stable operating temperature during long-term operation, thereby extending the service life of the equipment and improving the overall performance of the equipment.

[0033] The annular rack 26 is installed in meshing with the gear 23. By arranging the annular rack 26 on the drainage fan blade 25, a radial force can be generated on the gear 23, thereby indirectly driving the rotating shaft 22 to rotate, so that multiple fan blade assemblies 24 can rotate synchronously. Compared with directly installing a larger fan blade assembly 24 inside the output shaft body 15, the setting of multiple fan blade assemblies 24 can make the heat dissipation more uniform, effectively avoiding local overheating. At the same time, using the annular rack 26 to drive the gear 23 to rotate can increase the speed and wind pressure of the fan blade assembly 24, thereby improving the heat dissipation effect. The higher wind pressure helps the air to better penetrate the gap 28 inside the electromagnetic induction unit assembly 27, quickly taking away the heat, so that the temperature inside the motor body 11 remains low, further improving the heat dissipation rate. This design not only ensures the heat dissipation effect, but also helps to improve the operating efficiency and life of the motor.

[0034] A slide groove 29 is provided inside the filter air cover 14, and the end portion of the output shaft body 15 on the side close to the annular rack 26 extends out of the filter air cover 14. The output shaft body 15 is rotatably mounted with the filter air cover 14. A scraper 31 is fixedly mounted on the circumferential surface of the output shaft body 15. The scraper 31 is located on the outside of the filter air cover 14. The scraper 31 fits the surface of the filter air cover 14. A slider 32 is slidably mounted inside the slide groove 29. The scraper 31 and the slider 32 are fixedly mounted. An electromagnetic induction unit assembly 27 is provided inside the heat conduction inner shell 13. The electromagnetic induction unit assembly 27 is adapted to the output shaft body 15. The electromagnetic induction unit assembly 27 is left inside. There is a gap 28, and by providing a slide groove 29 on the outside of the filter air cover 14, when the output shaft body 15 drives the scraper 31 to rotate, the scraper 31 will simultaneously generate a radial force to drive the slider 32 to slide inside the slide groove 29 of the filter air cover 14, thereby providing additional support and guidance to improve stability, and by providing a slide groove 29 on the outside of the filter air cover 14, when the output shaft body 15 drives the scraper 31 to rotate, the scraper 31 will simultaneously generate a radial force to drive the slider 32 to slide inside the slide groove 29 of the filter air cover 14, thereby providing additional support and guidance to improve stability.

[0035] Working principle:

[0036] The first step is to power on the motor body 11. After the power is turned on, the staff can start the motor body 11. At this time, the start of the motor body 11 will cause the electromagnetic induction unit assembly 27 to generate electromagnetic induction and electromagnetic force. Therefore, the operation of the electromagnetic induction unit assembly 27 will drive the rotation of the output shaft body 15. At the same time, when the current passes through the winding of the electromagnetic induction unit assembly 27, Joule heat will be generated (the electrons in the current will collide and scatter with the atomic lattice when moving in the conductor. This collision process causes the kinetic energy of the electrons to be converted into The vibration energy of the conductor atoms, that is, heat energy, causes the winding of the electromagnetic induction unit assembly 27 to heat up. The winding is usually composed of a wire with a certain resistance. The existence of resistance hinders the free flow of current. In order to overcome the resistance, the current needs to consume energy, and this part of the consumed energy is expressed in the form of heat energy. At the same time, the output shaft body 15 will drive the drainage blades 25 to rotate, so that the drainage blades 25 inhale air through the filter cover 14 and blow it toward the surface of the heat dissipation housing 12 of the motor body 11, thereby completing the heat dissipation of the surface of the heat dissipation housing 12;

[0037] In the second step, when the output shaft body 15 rotates, the start of the output shaft body 15 will drive the guide blades 25 to rotate, and then drive the annular rack 26 to rotate, so that the annular rack 26 and the gear 23 on the rotating shaft 22 generate meshing transmission, so that the gear 23 generates a radial force synchronized with the rotation of the annular rack 26, and then rotates together, so that each gear 23 drives the rotating shaft 22 to rotate. At the same time, the filter core 19 inside the pipe 18 will provide the necessary air to the inside of the heat conduction inner shell 13, so that the fan blade assembly 24 inside the heat conduction inner shell 13 is blown toward the side of the one-way flow ventilation valve 21, so that the heat can be blown out through the one-way flow ventilation valve 21 in the second through groove 17, thereby completing the dual heat dissipation inside and outside the motor body 11;

[0038] In the third step, when the output shaft body 15 rotates, the rotation of the output shaft body 15 will generate a radial force on the scraper 31, so that the scraper 31 drives the slider 32 to slide inside the slide groove 29 of the filter cover 14. At the same time, the scraper 31 will clean the impurities remaining on the surface of the filter cover 14 to avoid the low air intake of the drainage fan blade 25 due to impurities clogging the air inlet of the filter cover 14.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
