Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to a motor that utilizes thermal radiation for heat dissipation. Background Art

[0002] Motor heat dissipation is an important factor that must be considered during the design and operation of motors. Because a large amount of heat is generated during the operation of the motor, if it is not dissipated in time, it will have a serious impact on the performance and lifespan of the motor. The conventional heat dissipation technologies used in motors generally include self-ventilation, forced ventilation, and natural convection, which allow air or coolant to flow through the heat dissipation surface of the motor to carry away the heat, thereby reducing the motor temperature.

[0003] A motor enhanced heat dissipation structure with the publication number CN114337098A includes at least one longitudinal eddy current generator. The longitudinal eddy current generator includes a triangular plate, and the triangular plate is arranged on the heat dissipation surface of the motor, and there is a certain included angle between the plate body of the triangular plate and the fluid flow direction of the heat dissipation surface of the motor.

[0004] A rotor heat dissipation structure of a sealed motor with the publication number CN113965019B. This heat dissipation structure includes two parts. The part located on the driving side of the rotor assembly structure includes a driving end cover, a radiator, and a rotor fan. The driving end cover is located on the outermost side, the radiator is matched and installed inside the driving end cover, the rotor fan is installed inside the radiator, and the rotor fan is snap-fitted on the driving end surface of the rotor assembly structure. The part located on the non-driving side of the rotor assembly structure includes a non-driving end cover and an end ring fairing.

[0005] Currently, most heat dissipation methods are achieved by setting a fan at the end of the rotor to dissipate heat inside it. However, due to the obstruction of the rotor and motor windings, etc., the overall heat dissipation effect is weak. Or heat sinks are set on the motor to achieve heat dissipation, but the air flow at the heat sink is low, resulting in a weak heat dissipation effect and a small heat dissipation area. Summary of the Invention

[0006] (1) Technical Problems to be Solved

[0007] The purpose of the present invention is to provide a motor that utilizes thermal radiation for heat dissipation to solve the above problems.

[0008] (2) Technical Solutions

[0009] To achieve the above purpose, the present invention provides the following technical solutions:

[0010] A motor that utilizes thermal radiation for heat dissipation provided by the present invention includes a motor winding and a rotor. Output shafts and connecting shafts are respectively connected to both ends of the rotor. A first heat conducting disc is arranged on the motor winding, and a second heat conducting disc is arranged on the output shaft. When the rotor rotates, the first heat conducting disc and the second heat conducting disc can rotate relative to each other.

[0012] Furthermore, a fan is arranged on the connecting shaft, and a number of evenly distributed fan blades are arranged on the outer side of the second heat-conducting disk along its circumferential direction. The air flow direction blown by the fan is consistent with the air flow direction blown by the fan blades.

[0013] Furthermore, an air flow gap is formed between adjacent first heat-conducting rings and second heat-conducting rings, and the radial dimension of the air flow gap is 0.08 mm - 0.12 mm.

[0014] Furthermore, an annular channel is opened at the position of the innermost first heat-conducting ring. A number of spray holes are opened on one side of the annular channel along the circumferential direction. The spray holes are communicated with the air flow gap. A pipe joint is connected to the outer side of the first heat-conducting disk, and the pipe joint is communicated with the annular channel. A water collecting groove is opened in the outermost first heat-conducting ring, and a drain pipe for discharging the water liquid inside the water collecting groove is connected to the bottom side of the first heat-conducting disk.

[0015] Furthermore, a number of heat sinks evenly distributed around the output shaft are arranged on the outer side of the motor winding. Thermal grease is arranged between each heat sink and the outer side of the motor winding. The heat sinks are arranged obliquely with respect to the axis of the output shaft. A number of air outlet channels evenly distributed along the circumferential direction are opened on the outer side wall of the second heat-conducting disk. One end of the air outlet channel is communicated with the air flow gap, and the other end of the air outlet channel blows air towards the heat sinks.

[0016] Furthermore, a rotary support assembly is arranged on the outer side of the motor winding. A brush assembly for cleaning the heat sinks and a locking structure for locking and connecting with the second heat-conducting disk are respectively arranged on the rotary support assembly. The rotary support assembly includes two support rings on the outer sides of the two axial ends of the motor winding. The inner side of each support ring is rotatably connected with an inner sleeve ring through a bearing. The two inner sleeve rings are fixedly connected with each other through a number of connecting plates. A number of opening grooves are opened on each support ring along its circumferential direction, and mounting holes are opened on the support ring at the opening grooves.

[0017] Further, there are more than three brush assemblies evenly distributed around the output shaft. The brush assembly includes a brush seat rod. A notch for passing through the end of the brush seat rod is formed on one side of the inner collar. Both ends of the brush seat rod are provided with first electric telescopic rods for driving its movement. The first electric telescopic rods are fixedly arranged on the inner collar through first brackets. The moving direction of the first electric telescopic rods driving the brush seat rod is consistent with the radial direction of the inner collar.

[0018] Further, the clamping structure includes a second bracket. One end of the second bracket is fixedly connected to the inner collar. The other end of the second bracket is fixedly provided with a mounting sleeve. A second electric telescopic rod is fixedly arranged in the mounting sleeve. The push rod head of the second electric telescopic rod faces the second heat conducting plate and is fixedly connected with a clamping plate. An anti-slip pad for abutting against the second heat conducting plate is arranged on the clamping plate.

[0019] Further, an oil storage structure is arranged at the center position of the first heat conducting plate. A shaft passing hole for passing through the output shaft is formed on the oil storage structure. The inner diameter of the shaft passing hole is larger than the outer diameter of the output shaft. The oil storage structure is made of fiberglass wool material.

[0020] Further, a connecting sleeve is fixedly arranged at the center position of the second heat conducting plate. The connecting sleeve is sleeved on the outside of the output shaft. The connecting sleeve and the output shaft are connected to each other by a key connection method.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By the relatively arranged first heat conducting plate and second heat conducting plate, the overall heat dissipation area can be increased and the heat dissipation effect can be improved. In addition, the first heat conducting plate is fixedly arranged on the motor winding, and the second heat conducting plate is arranged on the output shaft. When the second heat conducting plate rotates, it can drive the fan blade to rotate and blow the gas to flow for heat dissipation;

[0024] 2. The pipe joint is connected to the external gas supply device. The external gas supply device blows gas into the air flow gap through the pipe joint, the annular hole channel and the spray holes in sequence, diffuses from the center positions of the first heat conducting plate and the second heat conducting plate, and discharges the gas through the air outlet channel to blow towards the heat sink, thereby accelerating the air flow at the air flow gap and also accelerating the air flow at the heat sink position;

[0025] 3. When the second heat conducting plate rotates, the gas is ejected from the air outlet channel. Thus, the direction of the gas discharge is inclined. In order to avoid the heat sink blocking the air outlet direction, the heat sink is inclined, which can conform to the ejection direction of the air outlet channel, reduce the wind resistance and improve the heat dissipation efficiency;

[0026] 4. The rotation support assembly, the brush assembly, and the locking structure cooperate with each other. When the second heat conduction disk rotates with the output shaft, the bristles can clean the impurities and dust on the heat sink, and then cooperate with the air flow to blow out the cleaned dust, ensuring the heat dissipation effect of the heat sink.

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope protected by the present invention.

[0039] See Figures 1 - 9 As shown, the present invention provides a motor that uses thermal radiation for heat dissipation, including a motor winding 1 and a rotor 11. Output shafts 1101 and connecting shafts 1102 are respectively connected to both ends of the rotor 11. A first heat-conducting disk 2 is provided on the motor winding 1, and a second heat-conducting disk 3 is provided on the output shaft 1101. When the rotor 11 rotates, the first heat-conducting disk 2 and the second heat-conducting disk 3 can rotate relative to each other.

[0040] See the attached drawings of the specification Figure 6 and Figure 7As shown, a plurality of first heat conduction rings 201 and a plurality of second heat conduction rings 302 are respectively arranged on one side of the first heat conduction plate 2 and the second heat conduction plate 3 facing each other. The first heat conduction rings 201 and the second heat conduction rings 302 are arranged at intervals in a concentric circle and staggered with each other. An air flow gap is formed between the adjacent first heat conduction ring 201 and the second heat conduction ring 302. The radial dimension of the air flow gap is 0.08 mm - 0.12 mm. Specifically, the radial dimension of the air flow gap is 0.1 mm. Through the above specific structural design, the first heat conduction ring 201 extends between two second heat conduction rings 302, and the second heat conduction ring 302 extends between two first heat conduction rings 201, thereby realizing an air flow gap with a continuous S-shaped cross-sectional shape, greatly increasing the heat radiation conduction area and improving the heat radiation conduction efficiency.

[0041] See the attached drawings in the specification Figure 1 、 Figure 2 and Figure 9 As shown, a fan 7 is arranged on the connecting shaft 1102, and a plurality of fan blades 8 evenly distributed along the circumferential direction are arranged on the outer side of the second heat conduction plate 3. The air flow direction blown by the fan 7 is the same as the air flow direction blown by the fan blades 8. In practical applications, when the rotor 11 rotates, the fan 7 and the fan blades 8 can be driven to rotate simultaneously. The fan 7 and the fan blades 8 have the same rotational speed, and the air flow directions blown to the air are the same as each other, thereby realizing the full-range coverage and circulation of the air near the motor winding 1.

[0042] See the attached drawings in the specification Figure 7 and Figure 8As shown in the figure, a circular hole 204 is provided at the position of the innermost first heat conduction ring 201. A plurality of spray holes 203 evenly distributed along the circumferential direction are provided on one side of the circular hole 204. The spray holes 203 are communicated with the air flow gap. A pipe joint 202 is connected to the outside of the first heat conduction disk 2, and the pipe joint 202 is communicated with the circular hole 204. A water collecting groove 206 is provided in the outermost first heat conduction ring 201. A drain pipe 207 for discharging the water liquid inside the water collecting groove 206 is connected to the bottom side of the first heat conduction disk 2. Through the above specific structural design, the spray holes 203 are arranged at the central position of the first heat conduction disk 2. After the gas is ejected through the spray holes 203, the gas escapes from the air flow gap from the inside to the outside, so as to dissipate the heat from the inside to the outside, accelerate the air flow in the air flow gap, improve the heat dissipation efficiency of the first heat conduction disk 2 and the second heat conduction disk 3, and the gas flows through the air flow gap, inevitably causing the gas passing through it to be introduced to the positions of the motor winding 1 and the rotor 11. In order to avoid the influence of rust and the like on the contact between the motor winding 1 and the rotor 11 in the case of humid air, when the moisture condenses on the first heat conduction disk 2 and the second heat conduction disk 3 or is blocked and flung outward, and flows downward under its own gravity, it flows into the water collecting groove 206 for collection and is discharged through the drain pipe 207. Further, for emergency cooling in high-temperature situations, an air flow with water mist can be directly introduced through the pipe joint 202, so as to realize the rapid cooling of the first heat conduction disk 2 and the second heat conduction disk 3. At this time, the generated water droplets gather and flow into the water collecting groove 206 for collection.

[0043] See the attached drawings in the specification Figure 3 、 Figure 6 、 Figure 8 and Figure 9 As shown in the figure, a plurality of heat sinks 9 evenly distributed around the output shaft 1101 are provided on the outside of the motor winding 1. Thermal grease 10 is provided between each heat sink 9 and the outside of the motor winding 1. The heat sinks 9 are inclined with respect to the axis of the output shaft 1101. A plurality of air outlet channels 303 evenly distributed along the circumferential direction are provided on the outer side wall of the second heat conduction disk 3. One end of the air outlet channels 303 is communicated with the air flow gap, and the air outlet direction of the other end of the air outlet channels 303 points to the heat sinks 9.

[0044] See the attached drawings in the specification Figure 3 、 Figure 4 and Figure 5As shown in the figure, a rotating support assembly 4 is arranged on the outer side of the motor winding 1. A brush assembly 5 for cleaning the heat sink 9 and a locking structure 6 for engaging and connecting with the second heat conducting plate 3 are respectively arranged on the rotating support assembly 4. The rotating support assembly 4 includes two support rings 401 on the outer sides of both axial ends of the motor winding 1. The inner side of each support ring 401 is rotatably connected with an inner sleeve ring 402 through a bearing 403. The two inner sleeve rings 402 are fixedly connected to each other through a plurality of connecting plates 406. A plurality of opening grooves 404 are formed in each support ring 401 along its circumferential direction, and a mounting hole 405 is formed in the support ring 401 at the position of the opening groove 404. More than three brush assemblies 5 are arranged evenly centered on the output shaft 1101. The brush assembly 5 includes a brush seat rod 502. A notch 407 for passing through the end of the brush seat rod 502 is formed on one side of the inner sleeve ring 402. Both ends of the brush seat rod 502 are provided with a first electric telescopic rod 501 for driving its movement. The first electric telescopic rod 501 is fixedly arranged on the inner sleeve ring 402 through a first bracket 504. The moving direction of the first electric telescopic rod 501 driving the brush seat rod 502 is the same as the radial direction of the inner sleeve ring 402. The locking structure 6 includes a second bracket 601. One end of the second bracket 601 is fixedly connected to the inner sleeve ring 402. The other end of the second bracket 601 is fixedly provided with a mounting sleeve 602. A second electric telescopic rod 603 is fixedly arranged in the mounting sleeve 602. The push rod head end of the second electric telescopic rod 603 faces the second heat conducting plate 3 and is fixedly connected with a locking plate 604. An anti-slip pad 605 for abutting against the second heat conducting plate 3 is arranged on the locking plate 604. Through the above specific structural design, when it is necessary to clean dust and other impurities on the heat sink 9, the anti-slip pad 605 of the locking structure 6 contacts the second heat conducting plate 3 under the drive of the second electric telescopic rod 603. Thus, during the rotation of the second heat conducting plate 3 driven by the output shaft 1101, the inner sleeve ring 402 is driven to rotate. During the rotation of the inner sleeve ring 402, the push rod of the first electric telescopic rod 501 of the brush assembly 5 extends, so as to drive the brush bristles 503 to approach the heat sink 9 and contact the heat sink 9. And the brush seat rod 502 and the heat sink 9 are always in a separated state to avoid mutual interference. The brush bristles 503 are used to clean the heat sink 9, and cooperate with the rotating support assembly 4 to realize 360-degree cleaning of the heat sink 9. Moreover, the heat sink 9 is inclined, which can also achieve a better contact cleaning effect on the heat sink 9. Then, combined with the air flow, the cleaned dust is blown out. After the dust and impurities on the heat sink 9 are cleaned off, the heat dissipation effect of the heat sink 9 is better.

[0045] At the central position of the first heat conduction disk 2, an oil storage structure 12 is provided. A shaft-passing hole for passing through the output shaft 1101 is formed in the oil storage structure 12. The inner diameter of the shaft-passing hole is larger than the outer diameter of the output shaft 1101. The oil storage structure 12 is made of fiberglass wool material. Through the above specific structural design, the oil storage structure 12 can store lubricating oil.

[0046] At the central position of the second heat conduction disk 3, a connecting sleeve 301 is fixedly provided. The connecting sleeve 301 is sleeved outside the output shaft 1101, and the connecting sleeve 301 and the output shaft 1101 are connected to each other by a key connection method.

[0047] Finally, the working principle and technical effects of the present invention are specifically as follows:

[0048] During use, the first heat-conducting disc 2 and the motor winding 1 are fixed to each other by connecting bolts 205. The motor winding 1 conducts heat to the first heat-conducting disc 2 through direct contact. The second heat-conducting disc 3 is fixed to the output shaft 1101 by a key connection. During the rotation of the rotor 11, the rotor 11 drives the second heat-conducting disc 3 to rotate together through the output shaft 1101. The first heat-conducting disc 2 transfers heat to the second heat-conducting disc 3 through heat radiation. A fan blade 8 is fixedly arranged on the outer side of the second heat-conducting disc 3. When the second heat-conducting disc 3 rotates, it drives the fan blade 8 to rotate, and the fan blade 8 blows air to flow towards the heat sink 9 for heat dissipation. The pipe joint 202 is connected to an external air supply device. The external air supply device blows gas into the air flow gap through the annular channel 204 and the spray holes 203 in sequence through the pipe joint 202, diffuses from the central positions of the first heat-conducting disc 2 and the second heat-conducting disc 3 to the outside, and discharges the gas through the air outlet channel 303 and blows it towards the heat sink 9, so as to accelerate the air flow in the air flow gap and also accelerate the air flow at the position of the heat sink 9. In addition, since the second heat-conducting disc 3 sprays the gas from the air outlet channel 303 while rotating, the discharging direction of the gas is inclined. In order to prevent the heat sink 9 from blocking the air outlet direction, the heat sink 9 is inclined to conform to the spraying direction of the air outlet channel 303 to improve the heat dissipation efficiency. When introducing air into the air flow gap, in order to prevent the liquefaction of moisture in the air from having an adverse effect on the motor winding 1, water droplets accumulate and flow into the water collecting groove 206, and the water collecting groove 206 discharges the liquid through the drain pipe 207. When it is necessary to clean the heat sink 9, the push rod of the second electric telescopic rod 603 of the clamping structure 6 extends, so as to drive the clamping plate 604 to approach the second heat-conducting disc 3 and realize the contact between the anti-slip pad 605 and the second heat-conducting disc 3. During the rotation of the second heat-conducting disc 3, the inner sleeve ring 402 is driven to rotate through the frictional force and the clamping structure 6. During the rotation of the inner sleeve ring 402, the push rod of the first electric telescopic rod 501 of the brush assembly 5 extends, so as to drive the brush bristles 503 to approach the heat sink 9 and contact with the heat sink 9. The heat sink 9 is cleaned by the brush bristles 503, and the dust cleaned is blown out in cooperation with the air flow. After the dust and impurities on the heat sink 9 are cleaned, the heat dissipation effect of the heat sink 9 is better.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
