Description

Technical Field

[0001] This invention relates to the field of high-speed motors, and more particularly to a high-speed motor with efficient cooling. Background Technology

[0002] An existing Chinese patent, CN219394559U, describes a high-speed motorcycle motor that achieves rapid heat dissipation through the combined use of insulating oil, fan blades, cooling pipes, and a delivery pump. However, in this device, the end of the cooling pipe furthest from the delivery pump is fixedly connected to a cavity, and the inlet of the delivery pump is also connected to the cavity. The delivery pump keeps the insulating oil circulating, maintaining good heat dissipation. However, during delivery, because the inlet and outlet of the cavity are close together and there is no baffle within the cavity, the insulating oil is immediately drawn away by the delivery pump connected to the cavity outlet as soon as it enters the cavity from the cooling pipe and the cavity inlet. This causes the insulating oil to flow directly from the cavity inlet to the cavity outlet, rather than circulating throughout the entire cavity. Therefore, only the insulating oil near the cavity inlet and outlet can circulate and be cooled, while the insulating oil in other areas cannot circulate and be cooled, resulting in low motor heat dissipation efficiency, which needs improvement. Summary of the Invention

[0003] To overcome the shortcomings of the problems mentioned in the background, the present invention provides a high-speed motor with efficient cooling.

[0004] The technical solution is as follows: A high-speed motor with high-efficiency cooling includes a housing, mounting blocks, discs, a motor, and an output shaft; the housing is fixedly connected to several mounting blocks; the housing is connected to two symmetrically arranged discs via the mounting blocks; the two discs share a motor, and the discs are in close contact with the motor; the motor has an output shaft that passes through and is rotatably connected to the adjacent disc; it also includes a cover plate, partitions, hollow rings, spacers, connecting pipes, tee pipes, injection pipes, return pipes, and a pump; the discs have three annular cavities (inner, middle, and outer) from the inside out; each annular cavity has a cover plate; each inner annular cavity cover plate has an injection hole; each annular cavity has a partition plate, and all partitions on the same disc are arranged in a row; all discs share several tightly connected hollow rings, and all the middle... The hollow rings are all fitted to the outer annular surface of the motor, and the discs are in close contact with one side of their adjacent hollow rings; each hollow ring has a partition; each disc has one through hole 1, one through hole 2, and one through hole 3; each hollow ring has one through hole 4 and one through hole 5; the inner annular cavity is connected to the middle annular cavity through through hole 1; the middle annular cavity is connected to the outer annular cavity through through hole 2; each through hole 5 is connected to a connecting pipe; the outer annular cavity is connected to its adjacent connecting pipe through through hole 3; except for the two connecting pipes connected to through hole 3, the remaining connecting pipes are connected to through hole 4 on their adjacent hollow rings; the injection hole near the output shaft is connected to a tee pipe; the tee pipe is connected to an injection pipe, and the injection pipe passes through the housing and is connected to the outside; the tee pipe and the injection hole away from the output shaft are connected to a return pipe; a pump is installed in the return pipe.

[0005] Furthermore, it also includes a secondary shaft and a fan; the motor is provided with a secondary shaft, and the secondary shaft is fixedly connected to the output shaft; a fan is installed on the side of the housing away from the output shaft, and the rotating part of the fan is connected to the secondary shaft, the secondary shaft passes through the adjacent disk, and is rotatably connected to the adjacent disk.

[0006] Furthermore, the connecting tube is arranged in a ring around the outside of the hollow ring.

[0007] Furthermore, each connecting pipe has several fins evenly distributed along its curved curve.

[0008] Furthermore, the fins on each pair of adjacent connecting tubes are staggered.

[0009] Furthermore, it also includes a support and a filter screen; two symmetrically arranged supports are fixed to the housing, the two supports are located at two openings of the housing respectively, the output shaft and the secondary shaft pass through the adjacent supports and are rotatably connected to the adjacent supports; several filters are arranged between each support and the housing.

[0010] Furthermore, a connecting bar is fixed to both the output shaft and the secondary shaft; each connecting bar has several soft bristles on the side facing the motor, and the soft bristles on each connecting bar contact the filter screen on the corresponding side.

[0011] Furthermore, a number of transversely arrayed flow guide rings are provided on the inner side of the shell, and the flow guide rings are located between every two adjacent connecting pipes, and the cross-section of the flow guide rings is an inverted flat-topped cone shape.

[0013] 1. This invention utilizes the circulating flow of insulating oil to ensure that the insulating oil flows evenly across every area of ​​the outer surface of the motor, thereby achieving a good cooling and heat dissipation effect on every area of ​​the outer surface of the motor under the action of the insulating oil.

[0014] 2. In this invention, since the connecting pipe is annularly arranged around the outside of the hollow ring, the insulating oil absorbs heat from the area it flows through each time it passes through a hollow ring. Subsequently, the heat-absorbing insulating oil flows around the outside of the hollow ring within the connecting pipe before entering the next hollow ring. At this time, the airflow passing through the shell from back to front cools and dissipates heat on the insulating oil flowing within the connecting pipe, ensuring that it receives good cooling before entering the next hollow ring. When it flows through the next hollow ring, it also provides good cooling and heat dissipation to the motor area where the next hollow ring is located. Furthermore, since the connecting pipe is annularly arranged around the outside of the hollow ring, the flow distance of the insulating oil within the connecting pipe is extended, thereby extending the contact time between the insulating oil and the airflow, thus improving the cooling and heat dissipation effect on the insulating oil.

[0015] 3. The present invention increases the heat dissipation area of ​​the connecting pipe by using fins on the connecting pipe, thereby improving the heat dissipation effect of the airflow on the connecting pipe. Attached Figure Description

Detailed Implementation

[0028] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0029] Example 1

[0030] A high-speed motor with efficient cooling, such as Figures 1-10 As shown, it includes a housing 1, mounting blocks 2, discs 3, a motor 4, and an output shaft 5; the housing 1 is fixedly connected to several mounting blocks 2; the housing 1 is connected to two symmetrically arranged discs 3 through several mounting blocks 2; a motor 4 is arranged between the two discs 3, and the discs 3 are in contact with the motor 4; the motor 4 is provided with an output shaft 5, which passes through the adjacent disc 3 and is rotatably connected to the adjacent disc 3;

[0031] It also includes a cover plate 6, a partition plate 7, a hollow ring 8, a partition 9, a connecting pipe 10, a tee pipe 11, an injection pipe 12, a return pipe 13, and a pump 14; the disc 3 has three annular cavities from the inside to the outside: an inner, a middle, and an outer one; each annular cavity is provided with a cover plate 6; each inner annular cavity has an injection hole 6001 on its cover plate 6; each annular cavity has a partition plate 7, and all the partition plates 7 on the same disc 3 are arranged in a row; at least eight closely connected hollow rings 8 are provided between all the discs 3, and all the hollow rings 8 are attached to the annular outer side of the motor 4, and the disc 3 is closely connected to one side of its adjacent hollow ring 8; each hollow ring 8 has a partition 9; each disc 3 has a through hole 3001, a through hole 3002, and a through hole 3003. Each hollow ring 8 has a through hole 4 8001 and a through hole 5 8002; the inner annular cavity is connected to the middle annular cavity through through hole 1 3001; the middle annular cavity is connected to the outer annular cavity through through hole 2 3002; each through hole 5 8002 is connected to a connecting pipe 10; the outer annular cavity is connected to its adjacent connecting pipe 10 through through hole 3 3003; except for the two connecting pipes 10 connected to through hole 3 3003, the other connecting pipes 10 are connected to through holes 4 8001 on their adjacent hollow rings 8; the injection hole 6001 near the output shaft 5 is connected to a three-way pipe 11; the three-way pipe 11 is connected to an injection pipe 12, and the injection pipe 12 passes through the housing 1 and is connected to the outside; the three-way pipe 11 and the injection hole 6001 away from the output shaft 5 are connected to a return pipe 13; a pump 14 is installed in the return pipe 13.

[0032] It also includes a secondary shaft 20 and a fan 21; the motor 4 is provided with a secondary shaft 20, and the secondary shaft 20 is fixedly connected to the output shaft 5; the fan 21 is installed on the side of the housing 1 away from the output shaft 5, and the rotating part of the fan 21 is connected to the secondary shaft 20, the secondary shaft 20 passes through the adjacent disk 3, and is rotatably connected to the adjacent disk 3.

[0033] The connecting pipe 10 is arranged in a ring around the outside of the hollow ring 8.

[0034] The specific workings of this invention are as follows:

[0035] When the motor 4 is working, the output shaft 5 rotates, driving the secondary shaft 20 and the fan 21 to rotate together. The rotating fan 21 outputs airflow from back to front into the housing 1, and the airflow provides ventilation and heat dissipation for the motor 4 inside the housing 1.

[0036] Simultaneously, the oil supply equipment controlling the external device sequentially injects insulating oil into the inner annular cavity of the front disc 3 through the injection pipe 12, the three-way pipe 11, and the injection hole 6001. This causes the insulating oil to flow in a ring around the inner annular cavity of the front disc 3, and after filling the inner annular cavity, it flows through the through hole 3001 on the front disc 3 into the middle annular cavity. The insulating oil then flows around the middle annular cavity of the front disc 3, and after filling the middle annular cavity, it flows from the front... The through hole 3002 on the square disk 3 flows into the outer annular cavity of the front disk 3. The insulating oil flows around the outer annular cavity of the front disk 3 and, after filling the outer annular cavity of the front disk 3, flows from the through hole 3003 on the front disk 3 to the foremost connecting pipe 10. During this process, the insulating oil flows in multiple annular trajectories from the inside to the outside in the front disk 3, thereby flowing evenly through every area of ​​the front disk 3 and achieving a good cooling and heat dissipation effect on every area of ​​the front disk 3.

[0037] Next, the insulating oil enters the frontmost hollow ring 8 through the through hole 8001 on the frontmost hollow ring 8 from the frontmost connecting pipe 10. After flowing in a ring around the internal cavity of the frontmost hollow ring 8, it enters the next connecting pipe 10 through the through hole 8002 on the frontmost hollow ring 8. Then, it enters the next hollow ring 8 through the next connecting pipe 10 and the through hole 8001. After flowing in a ring around the internal cavity of the next hollow ring 8, it enters the next connecting pipe 10 behind it through the through hole 8002 on the next hollow ring 8. This process is repeated many times. The insulating oil flows evenly through each hollow ring 8. Since all the hollow rings 8 are attached to the annular outer surface of the motor 4, during this flow process, the insulating oil will flow evenly from front to back through every area of ​​the outer surface of the motor 4, which will have a good cooling and heat dissipation effect on every area of ​​the outer surface of the motor 4.

[0038] Finally, the insulating oil enters the outer annular cavity of the rear disk 3 through the third through-hole 3003 from the rear connecting pipe 10. The insulating oil flows around the outer annular cavity of the rear disk 3 and, after filling it, flows through the second through-hole 3002 into the middle annular cavity of the rear disk 3. The insulating oil then flows around the middle annular cavity of the rear disk 3 and, after filling it, flows through the first through-hole 3001 into the inner annular cavity of the rear disk 3. Finally, it flows around the inner annular cavity of the rear disk 3 and fills it. After passing through the inner annular cavity, the insulating oil enters the return pipe 13 through the injection hole 6001. During this process, the insulating oil flows in multiple annular trajectories from the outside to the inside in the rear disc 3, thus flowing evenly through every area of ​​the rear disc 3 and providing good cooling and heat dissipation for every area of ​​the rear disc 3. At the same time, the pump 14 is controlled to operate, transporting the insulating oil entering the return pipe 13 into the three-way pipe 11, so that the insulating oil can circulate and flow evenly through every area of ​​the outer side of the motor 4, so that every area of ​​the outer side of the motor 4 can achieve good cooling and heat dissipation under the action of the insulating oil.

[0039] It should be noted that, since the connecting pipe 10 is annularly arranged around the outside of the hollow ring 8, the insulating oil absorbs heat from the area it flows through each time it passes through a hollow ring 8. Subsequently, the heat-absorbing insulating oil flows around the outside of the hollow ring 8 within the connecting pipe 10 before entering the next hollow ring 8. At this time, the airflow passing through the housing 1 from back to front cools and dissipates heat from the insulating oil flowing within the connecting pipe 10, ensuring that it receives good cooling before entering the next hollow ring 8. When it flows through the next hollow ring 8, it also provides good cooling and heat dissipation to the part of the motor 4 area where the next hollow ring 8 is located. Furthermore, since the connecting pipe 10 is annularly arranged around the outside of the hollow ring 8, the flow distance of the insulating oil within the connecting pipe 10 is extended, thereby extending the contact time between the insulating oil and the airflow, thus improving the cooling and heat dissipation effect on the insulating oil.

[0040] In addition, some existing technologies generally absorb the heat generated by the motor 4 by circulating insulating oil in the S-shaped or spiral circulation channel inside the heat sink, and then use the coiled cooling pipes to specifically cool the insulating oil flowing in the cooling pipes. Although this can also achieve the effect of circulating heat dissipation, the insulating oil will continuously absorb heat during each flow in the circulation channel, and the temperature of the insulating oil will gradually rise while the heat absorption effect will gradually decrease. The area of ​​the motor 4 at the end of its flow path receives poor cooling and heat dissipation.

[0041] The present invention utilizes the cooling effect of the fan 21 to directly act on the connecting pipe 10 through which insulating oil flows. Through the cooperation between the disc 3 and the connecting pipe 10 and the "one in, one out" flow pattern, the cooling effect of the fan 21 can not only act on the motor 4 covered by the disc 3, but also act on the insulating oil flowing in the connecting pipe 10 in a timely manner, so that the insulating oil always maintains a good cooling effect.

[0042] Example 2

[0043] Based on the above embodiment 1, as follows Figures 3-4 As shown, each connecting pipe 10 has several fins 30 evenly distributed along its curved curve. The fins 30 on the connecting pipe 10 increase the heat dissipation area of ​​the connecting pipe 10 and improve the heat dissipation effect of the airflow when it passes through the connecting pipe 10.

[0044] The fins 30 on each pair of adjacent connecting pipes 10 are staggered, so that the fins 30 are dispersed and the fins 30 are closely overlapping, which helps to ensure heat dissipation.

[0045] Example 3

[0046] Based on the above embodiment 2, such as Figure 1-Figure 2 As shown, it also includes a bracket 40 and a filter 41; two symmetrically arranged brackets 40 are fixedly connected to the housing 1, and the two brackets 40 are respectively located at two openings of the housing 1. The output shaft 5 and the sub-shaft 20 each pass through the adjacent bracket 40 and are rotatably connected to the adjacent bracket 40 to improve the operating stability of the output shaft 5 and the sub-shaft 20; several filters 41 are jointly arranged between each bracket 40 and the housing 1. The filter 41 located in front of the motor 4 and the filter 41 located behind the motor 4 respectively intercept and filter dust particles from the front opening and the rear opening of the housing 1, preventing dust particles from entering the interior of the housing 1 from the front opening and the rear opening, thus achieving dust prevention and extending the maintenance cycle.

[0047] like Figure 3 As shown, each of the output shaft 5 and the sub-shaft 20 is fixedly connected to a connecting bar 42; each connecting bar 42 has several soft bristles on the side facing the motor 4, and the soft bristles on each connecting bar 42 are in contact with the filter screen 41 on the corresponding side. When the output shaft 5 and the sub-shaft 20 rotate, they drive the connecting bar 42 and its soft bristles to rotate together. The soft bristles clean the dust particles intercepted on the filter screen 41, preventing the dust particles from clogging the mesh of the filter screen 41, affecting airflow and reducing heat dissipation efficiency.

[0048] like Figure 3 and Figure 11As shown, a number of transversely arrayed guide rings 50 are provided on the inner side of the housing 1, and the guide rings 50 are located between every two adjacent connecting pipes 10. The cross-section of the guide rings 50 is an inverted flat-topped cone. When the airflow passes through the housing 1 from back to front, the airflow near the inner side of the housing 1 will be deflected by the guide rings 50 and blown towards the area between two adjacent connecting pipes 10, thereby cooling the opposing surfaces of the two adjacent connecting pipes 10 and preventing the area between two adjacent connecting pipes 10 from being blocked by the adjacent connecting pipes 10 and thus not receiving a good airflow cooling effect.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
