Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor that dissipates heat by thermal radiation. Background Art

[0002] Motor heat dissipation is an important factor that must be considered during motor design and operation, because the motor will generate a lot of heat during operation. If it is not dissipated in time, it will have a serious impact on the performance and life of the motor. The conventional heat dissipation technology used by the motor is generally self-ventilation, forced ventilation, and natural convection, so that air or coolant flows through the heat dissipation surface of the motor to take away the heat, thereby reducing the temperature of the motor.

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

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

The air flow at the heat sink is low, resulting in weak heat dissipation effect and small heat dissipation area. Summary of the invention

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] See also Figure 1-Figure 9 As shown, the present invention provides a motor that dissipates heat by heat radiation, including a motor winding 1 and a rotor 11, wherein two ends of the rotor 11 are respectively connected to an output shaft 1101 and a connecting shaft 1102, a first heat conducting plate 2 is arranged on the motor winding 1, and a second heat conducting plate 3 is arranged on the output shaft 1101, and when the rotor 11 rotates, the first heat conducting plate 2 and the second heat conducting plate 3 can rotate relative to each other;

[0040] See the instruction manual Figure 6 and Figure 7As shown, a plurality of first heat-conducting rings 201 and a plurality of second heat-conducting rings 302 are respectively arranged on the opposite sides of the first heat-conducting plate 2 and the second heat-conducting plate 3, and the first heat-conducting rings 201 and the second heat-conducting rings 302 are arranged alternately and concentrically. An air flow gap is formed between the adjacent first heat-conducting rings 201 and the second heat-conducting rings 302, and the radial dimension of the air flow gap is 0.08mm-0.12mm. Specifically, the radial dimension of the air flow gap is 0.1mm. Through the above-mentioned specific structural design, the first heat-conducting ring 201 extends between the two second heat-conducting rings 302, and the second heat-conducting ring 302 extends between the two first heat-conducting 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 instruction manual Figure 1 , Figure 2 and Fig. 9 As shown, a fan 7 is provided on the connecting shaft 1102, and a plurality of evenly distributed fan blades 8 are provided on the outer side of the second heat conducting plate 3 along its circumferential direction, and the flow direction of the air blown by the fan 7 is consistent with the flow direction of the air 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 at the same time, and the fan 7 and the fan blades 8 have the same rotation speed, and the blowing flow directions of the air are consistent with each other, thereby achieving full coverage and circulation of the air near the motor winding 1.

[0042] See the instruction manual Figure 7 and Figure 8As shown, an annular channel 204 is provided at the position of the innermost first heat-conducting ring 201, and a plurality of spray holes 203 evenly distributed along the circumferential direction are provided on one side of the annular channel 204, the spray holes 203 are communicated with the air flow gap, a pipe joint 202 is connected to the outer side of the first heat-conducting plate 2, the pipe joint 202 and the annular channel 204 are communicated with each other, a water collecting groove 206 is provided in the outermost first heat-conducting ring 201, and a drain pipe 207 for discharging water in the water collecting groove 206 is connected to the bottom side of the first heat-conducting plate 2. Through the above-mentioned specific structural design, the spray hole 203 is arranged at the center position of the first heat-conducting plate 2, so that after the gas is sprayed out through the spray hole 203, the gas dissipates from the air flow gap from the inside to the outside, thereby dissipating the heat from the inside to the outside, accelerating the air flow in the air flow gap, and improving the heat dissipation efficiency of the first heat-conducting plate 2 and the second heat-conducting plate 3. The gas circulates in the air flow gap, which inevitably leads to the gas passing through it being introduced into the position of the motor winding 1 and the rotor 11. In order to avoid rust and other effects caused by the contact between the motor winding 1 and the rotor 11 in the case of humid air, the moisture condenses on the first heat-conducting plate 2 and the second heat-conducting plate 3 or is blocked and thrown outward. When it flows downward under its own gravity, it flows into the water collecting groove 206 for collection and is discharged through the drain pipe 207. Furthermore, for emergency cooling under high temperature conditions, an air flow with water mist can be directly introduced through the pipe joint 202, so that the first heat-conducting plate 2 and the second heat-conducting plate 3 can be quickly cooled. At this time, the water droplets generated condense and flow into the water collecting groove 206 for collection.

[0043] See the instruction manual Figure 3 , Figure 6 , Figure 8 and Fig. 9 As shown, a plurality of heat sinks 9 evenly distributed around the output shaft 1101 are provided on the outside of the motor winding 1, and thermal grease 10 is provided between the heat sink 9 and the outside of the motor winding 1. The heat sink 9 is inclined to the axis of the output shaft 1101, and a plurality of evenly distributed air outlet channels 303 are provided on the outer side wall of the second heat conducting plate 3 along its circumferential direction, one end of the air outlet channel 303 is connected to the air flow gap, and the air outlet direction of the other end of the air outlet channel 303 points to the heat sink 9.

[0044] See the instruction manual Figure 3 , Figure 4 and Figure 5As shown, a rotating support assembly 4 is provided on the outer side of the motor winding 1, and a brush assembly 5 for cleaning the heat sink 9 and a locking structure 6 for locking and connecting with the second heat conducting plate 3 are respectively provided on the rotating support assembly 4. The rotating support assembly 4 includes two support rings 401 along the outer sides of the axial ends of the motor winding 1, and the inner side of each support ring 401 is rotatably connected to an inner ring 402 through a bearing 403, and the two inner rings 402 are fixedly connected to each other through a plurality of connecting plates 406, and each support ring 401 is provided with a plurality of open grooves 404 along its circumferential direction, and a mounting hole 405 is provided on the support ring 401 located at the open groove 404. The brush assembly 5 is provided with more than three evenly distributed around the output shaft 1101, and the brush assembly 5 includes a brush seat rod 502. A notch 407 for passing the end of the brush seat rod 502 is opened on one side of the inner ring 402, and a first electric telescopic rod 501 for driving the brush seat rod 502 to move is provided at both ends of the brush seat rod 502. The first electric telescopic rod 501 is fixedly arranged on the inner ring 402 by a first bracket 504, and the movement direction of the brush seat rod 502 driven by the first electric telescopic rod 501 is consistent with the radial direction of the inner ring 402. The locking structure 6 includes a second bracket 601, one end of the second bracket 601 is fixedly connected to the inner 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 provided inside the mounting sleeve 602, a push rod head end of the second electric telescopic rod 603 faces the second heat conducting disk 3 and is fixedly connected to a locking plate 604, and a non-slip pad 605 for abutting against the second heat conducting disk 3 is provided on the locking plate 604. Through the above-mentioned specific structural design, when it is necessary to clean the heat sink 9 from dust and other impurities, the anti-slip pad 605 of the locking structure 6 contacts with the second heat conducting plate 3 under the drive of the second electric telescopic rod 603, so that the inner ring 402 is driven to rotate during the rotation of the second heat conducting plate 3 driven by the output shaft 1101. During the rotation of the inner ring 402, the push rod of the first electric telescopic rod 501 of the brush assembly 5 is extended, thereby driving the bristles 503 to approach the heat sink 9 and contact the heat sink 9, while the brush seat rod 502 and the heat sink 9 are always in a separated state to avoid mutual interference. The bristles 503 are used to clean the heat sink 9, and cooperate with the rotating support assembly 4 to clean the heat sink 9 at 360 degrees. The heat sink 9 is inclined, which can also achieve a better contact and cleaning effect on the heat sink 9, and then cooperate with the air flow to blow out the cleaned dust. After the dust and impurities on the heat sink 9 are cleaned, the heat sink 9 has a better heat dissipation effect.

[0045] An oil storage structure 12 is provided at the center of the first heat conducting plate 2. The oil storage structure 12 is provided with a through-shaft hole for passing the output shaft 1101. The inner diameter of the through-shaft hole is larger than the outer diameter of the output shaft 1101. The oil storage structure 12 is made of glass fiber wool. Through the above-mentioned specific structural design, the oil storage structure 12 can store lubricating oil.

[0046] A connecting sleeve 301 is fixedly provided at the center of the second heat conducting plate 3 . The connecting sleeve 301 is sleeved on the outside of the output shaft 1101 . The connecting sleeve 301 and the output shaft 1101 are connected to each other by a key connection.

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

[0048] When in use, the first heat-conducting disk 2 and the motor winding 1 are fixed to each other by connecting bolts 205, and the motor winding 1 conducts heat to the first heat-conducting disk 2 by direct contact, and the second heat-conducting disk 3 is fixed to the output shaft 1101 by key connection. During the rotation of the rotor 11, the rotor 11 drives the second heat-conducting disk 3 to rotate together through the output shaft 1101, and the first heat-conducting disk 2 transfers heat to the second heat-conducting disk 3 by thermal radiation. The outer side of the second heat-conducting disk 3 is fixedly provided with fan blades 8. When the second heat-conducting disk 3 rotates, the fan blades 8 are driven to rotate, and the fan blades 8 are directed toward the heat dissipation. The heat sheet 9 blows the gas to flow and dissipate heat; the pipe joint 202 is connected to the external air supply device, and the external air supply device blows gas into the air flow gap through the annular hole 204 and the nozzle 203 in sequence through the pipe joint 202, diffuses outward from the center position of the first heat conducting plate 2 and the second heat conducting plate 3, and discharges the gas from the air outlet channel 303 to the heat sink 9, thereby accelerating the air flow in the air flow gap and the air flow at the heat sink 9 position. In addition, since the second heat conducting plate 3 is rotating and sprays the gas from the air outlet channel 303, the gas is discharged from the second heat conducting plate 3 and blown to the heat sink 9. The direction of gas discharge is inclined. In order to avoid the heat sink 9 blocking the air outlet direction, the heat sink 9 is tilted to follow the ejection direction of the air outlet duct 303 to improve the heat dissipation efficiency. When the air is introduced into the air flow gap, in order to avoid the adverse effect of liquefaction of water in the air on the motor winding 1, water droplets accumulate and flow into the water collecting groove 206, and the water collecting groove 206 discharges the water through the drain pipe 207. When the heat sink 9 needs to be cleaned, the second electric telescopic rod 603 push rod of the locking structure 6 is extended, thereby driving the locking plate 604 to close the locking plate 604. The brush 605 is close to the second heat-conducting plate 3 and the anti-skid pad 605 is in contact with the second heat-conducting plate 3. During the rotation of the second heat-conducting plate 3, the inner ring 402 is driven to rotate by the friction force and the locking structure 6. During the rotation of the inner ring 402, the first electric telescopic rod 501 of the brush assembly 5 is extended, thereby driving the bristles 503 to approach the heat sink 9 and contact with the heat sink 9. The bristles 503 are used to clean the heat sink 9, thereby cooperating with the air flow to blow out the cleaned dust. After the dust and impurities on the heat sink 9 are cleaned, the heat dissipation effect of the heat sink 9 is better.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
