Description

Technical Field

[0001] The present invention relates to the technical field of high-efficiency motors, and particularly to a high-efficiency motor based on the conversion of commercial vehicles from fuel to electricity. Background Art

[0002] As a type of high-efficiency motor, the flat wire motor uses flat coils instead of traditional round coils. This design can reduce the volume and weight of the motor, improve the heat dissipation performance, and thus improve the efficiency. At the same time, the flat wire motor can arrange the coils more closely to increase the coil filling rate, and has a higher power density compared to traditional motors, enabling the flat wire motor to provide a higher power output under the same volume.

[0003] According to the patent publication number CN115459494A, publication date: December 9, 2022, there is disclosed a high-efficiency oil-cooled motor, including a housing, a front cover plate, a rear cover plate, a stator, a rotating shaft, and a rotor core. The stator is arranged inside the housing. The front cover plate and the rear cover plate are respectively fixed at both ends of the housing. The rotor core is arranged on the rotating shaft, and both ends of the rotating shaft are respectively rotatably arranged on the front cover plate and the rear cover plate through bearings. An axial oil passage penetrating the rotating shaft is further provided on the rotating shaft. A plurality of middle radial oil passages are further provided on the rotating shaft, and the plurality of middle radial oil passages communicate with the axial oil passage. A plurality of rotor oil passages extending from the center of the rotor core to both ends and the outside are further provided on the rotor core, and the rotor oil passages communicate with the corresponding middle radial oil passages. A cooling oil inlet B is further provided on the front cover plate, and the cooling oil inlet B communicates with the axial oil passage. A water channel spirally arranged along the circumference is provided inside the side wall of the housing. A water channel inlet and a water channel outlet for connecting a heat management water pump are further provided on the side wall of the housing. A cooling oil pipe is further arranged inside the water channel. A cooling oil inlet A is further provided on the side wall of the housing. A ring groove oil passage is further provided on the outer wall of the stator. The cooling oil inlet A penetrates the housing between two adjacent water channels and then communicates with the ring groove oil passage. One end of the cooling oil pipe is inserted into the rear cover plate and then communicates with the inside of the housing. The other end of the cooling oil pipe communicates with the cooling oil inlet A and the cooling oil inlet B.

[0004] In the prior art including the above patents, for the heat dissipation of high-efficiency motors in commercial vehicles, there is natural heat dissipation through the housing, and there are also methods such as air cooling, water cooling, and oil cooling to achieve the effect of rapid heat dissipation. The relatively common and most frequently used cooling method is oil cooling. Through the circulating flow of the cooling oil in the high-efficiency motor, combined with external heat dissipation, the heat in the motor is taken out, so as to achieve the purpose of efficient heat dissipation. At present, the way of pumping the cooling oil into the high-efficiency motor adopts the axial oil passage and radial oil passage in the rotating shaft in the above patents, so as to pump the cooling oil along the rotating shaft into the motor to achieve the heat dissipation effect. Compared with the traditional air cooling or stator oil spraying, this method has a stronger heat dissipation effect. For the flat wire in the high-efficiency motor, a lot of heat will be generated during its use, and the two ends of the flat wire on the stator are usually the places with the highest heat. This is mainly because when the motor runs and the current passes through the flat wire, the connection points between the wiring end and the coil (i.e., the two ends of the flat wire) usually bear a large current. Therefore, higher resistance heat is easily generated at these positions. Although the cooling oil sprayed out along the rotating shaft and the rotor in the above patents fills the cavity between the housing, stator and rotor, the sprayed cooling oil does not directly act on the two ends of the flat wire, so its heat dissipation effect on the two ends of the flat wire is poor.

Detailed implementation manners

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0036] As Figures 1-13 shown, a high-efficiency motor based on the conversion of commercial vehicle fuel to electricity includes a stator component 3 and a rotor rod 2 rotating therein, and further includes a housing 1 wrapped around the stator component 3. A first oil chamber 12 is provided between one end of the housing 1 and the stator component 3.

[0037] The stator component 3 is provided with an inner layer flat wire winding. The inner layer flat wire winding includes a first end group arranged in a circular array. The first end group includes a first adapter end 54 and a second adapter end 55. An inner probe rod 4 arranged in a circular array and located between the first adapter end 54 and the second adapter end 55 respectively is fixedly installed at the end of the stator component 3. A plurality of drip holes 42 opened on the inner probe rod 4 face the rotor component 26 fixedly installed on the outer wall of the rotor rod 2, and an interface 41 communicating with the plurality of drip holes 42 is opened on the inner probe rod 4.

[0038] The spray plate 22 fixedly installed on the outer wall of the rotor rod 2 moves in the first oil chamber 12. The first adapter end 54, the second adapter end 55 and the interface 41 are respectively located on the oil spraying paths of a plurality of oblique spray orifices 23 opened on the side of the spray plate 22.

[0039] Specifically, an oil inlet passage 21 communicating with the plurality of oblique spray orifices 23 is opened in the rotor rod 2. A clearance chamber 27 communicating with the first oil chamber 12 is provided between the outer wall of the rotor component 26 and the inner wall of the stator component 3. The inner probe rod 4 is fixedly installed on the inner wall of the stator component 3, and the drip holes 42 are located in the clearance chamber 27. The stator component 3 is provided with winding slots 31 arranged in a circular array, and the inner layer flat wire winding is arranged in the winding slots 31. The stator component 3 is fixedly installed in the housing 1.

[0040] Furthermore, cooling oil is pumped into the oil inlet 21 by an oil pump, and then the cooling oil is sprayed out from multiple oblique nozzles 23 along the oil inlet 21, and then as the rotor rod 2 rotates in the stator component 3, the rotor rod 2 drives the spray plate 22 to rotate, and at the same time, the multiple oblique nozzles 23 successively pass over the first adapter end 54, the second adapter end 55 and the interface 41, and the multiple oblique nozzles 23 are directly sprayed on the first adapter end 54 and the second adapter end 55, so that the rapidly sprayed cooling oil dissipates the heat of the first adapter end 54 and the second adapter end 55. Compared with traditional immersion cooling, directly spraying on the first adapter end 54 and the second adapter end 55 can improve the heat dissipation effect of the first adapter end 54 and the second adapter end 55, and at the same time, the cooling oil passing along the oil inlet 21 can dissipate a certain amount of heat to the rotor component 26 on the rotor rod 2.

[0041] Furthermore, when the inclined nozzle 23 is rotatingly sprayed and the inclined nozzle 23 is directly opposite to the interface 41, the cooling oil sprayed at high speed is poured into the inner probe rod 4, and then the cooling oil poured into the inner probe rod 4 flows out to the gap cavity 27 along the multiple drip holes 42. At this time, the heat of the stator component 3 is absorbed by the inner probe rod 4, and then the cooling oil flowing in the inner probe rod 4 takes away the heat on the inner probe rod 4, thereby achieving a certain heat dissipation effect on the stator component 3. Furthermore, the cooling oil flowing into the gap cavity 27 can dissipate heat for the rotor component 26 and the inner wall of the stator component 3. Under the continuous oil discharge of the multiple drip holes 42, the oil in the gap cavity 27 is discharged into the first oil cavity 12.

[0042] In the above technical solution, cooling oil is sprayed directly to the first adapter end 54 and the second adapter end 55 through multiple inclined nozzles 23, so that the heat dissipation efficiency of the first adapter end 54 and the second adapter end 55 is increased under the action of the high-speed flowing cooling oil, and then the multiple inclined nozzles 23 are connected with the interface 41 in sequence, so that the multiple drip holes 42 spray out cooling oil and dissipate heat to the stator part 3 and the rotor part 26 at the same time, and the cooling oil flowing in the inner probe rod 4 can absorb and dissipate the heat of the stator part 3, and then improve the heat dissipation effect of the motor through multi-directional heat dissipation, thereby improving the motor efficiency.

[0043] As an embodiment further provided by the present invention, a second oil chamber 13 is provided between the casing 1 and the other end of the stator component 3, and a plurality of oil passages 32 are provided on the stator component 3 to connect the first oil chamber 12 and the second oil chamber 13 to each other.

[0044] Specifically, the housing 1 is provided with an oil outlet 11 , and a part of the structure of the inner flat wire winding is located in the second oil chamber 13 .

[0045] Furthermore, by utilizing multiple oil passages 32, when the inclined injection port 23 rotates and injects, the inclined injection port 23 directly injects cooling oil to dissipate heat from the first adapter end 54 and the second adapter end 55, thereby accelerating the heat dissipation efficiency of the first adapter end 54 and the second adapter end 55. When multiple inclined injection ports 23 are sequentially docked with the interface 41, the cooling oil is sprayed from multiple drip holes 42 to dissipate heat from the inner wall of the stator member 3 and the rotor member 26 simultaneously. Then, the cooling oil accumulates in the first oil chamber 12, and when the cooling oil accumulates in the first oil chamber 12, the oil pressure gradually increases. At this time, under the action of the oil pressure, the cooling oil begins to flow along multiple oil passages 32 into the second oil chamber 13. Then, the cooling oil accumulates in the second oil chamber 13, and the flowing cooling oil dissipates heat from the inner layer of flat wire windings in the second oil chamber 13. Then, the cooling oil in the second oil chamber 13 is discharged along the oil outlet 11 and circulates for heat dissipation after passing through the oil pump.

[0046] Furthermore, when the cooling oil passes through multiple oil passages 32 on the stator member 3, the cooling oil in the oil passages 32 can absorb the heat on the stator member 3, thereby further dissipating heat from the stator member 3.

[0047] As another embodiment provided by the present invention, a notch portion 43 is provided on the outer wall of one side of the inner probe rod 4, and the notch portion 43 is located on the oil injection path of the inclined injection port 23.

[0048] Specifically, in order to enable the inclined injection port 23 to spray and dissipate heat from the first adapter end 54 and the second adapter end 55 more comprehensively, as Figure 9 shown by the arrow direction, there is a certain angle between the injection direction of the inclined injection port 23 and the first adapter end 54 and the second adapter end 55. When the spray plate 22 rotates, at this time, the inclined injection port 23 sequentially sprays on the front surfaces of the first adapter end 54 and the second adapter end 55. Then, as the spray plate 22 continues to rotate, the inclined injection port 23 sequentially sprays on the notch portion 43 on the inner probe rod 4. At this time, under the shielding of the notch portion 43, the cooling oil sprayed by the inclined injection port 23 splashes on the back surfaces of the first adapter end 54 and the second adapter end 55. Thus, through the direct injection of the inclined injection port 23 and the shielding and splashing of the cooling oil by the notch portion 43, the first adapter end 54 and the second adapter end 55 are cooled more comprehensively. Compared with the impact cooling on one side of the first adapter end 54 and the second adapter end 55, by cooling the side walls of both sides of the first adapter end 54 and the second adapter end 55, the heat dissipation effect can be improved.

[0049] As yet another embodiment provided by the present invention, it further includes a middle-layer flat wire winding. The middle-layer flat wire winding includes a second end group arranged in a circular array. The second end group includes a third connection end 52 and a fourth connection end 53. The third connection end 52 is attached to the first connection end 54, and the fourth connection end 53 is attached to the second connection end 55. The third connection end 52 and the fourth connection end 53 are respectively located on the oil injection paths of a plurality of inclined nozzles 23.

[0050] Specifically, the middle-layer flat wire winding is arranged in the winding slot 31 and is adjacent to the inner-layer flat wire winding. As an additional flat wire winding layer, the middle-layer flat wire winding improves the power density and efficiency of the motor. As the number of winding layers increases, the copper wire filling rate of the motor increases, and the cross-sectional area of the wire increases, thereby reducing the resistance of the wire. During the rotation of the spray plate 22, the inclined nozzles 23 not only dissipate heat from the first connection end 54 and the second connection end 55. Since the third connection end 52 and the fourth connection end 53 are respectively located on the oil injection paths of a plurality of inclined nozzles 23, the inclined nozzles 23 will sequentially spray the third connection end 52, the first connection end 54, the fourth connection end 53, and the second connection end 55. The cooling oil sprayed through the inclined nozzles 23 directly acts on the connection ends of the flat wire winding, so that all the connection ends can be cooled by the rapidly sprayed cooling oil, enabling both the middle-layer flat wire winding and the inner-layer flat wire winding to directly receive the cooling effect of the direct spray from the inclined nozzles 23, reducing the shielding of the third connection end 52 and the fourth connection end 53 by the first connection end 54 and the second connection end 55 during the spraying process, and thus making full use of the cooling oil sprayed by the inclined nozzles 23.

[0051] As yet another embodiment provided by the present invention, the outer walls on the front side of the fourth connection end 53 and the second connection end 55 are arc-connected, and the outer walls on the front side of the third connection end 52 and the first connection end 54 are arc-connected.

[0052] Specifically, as Figure 8 shown, the outer walls of the third connection end 52 and the first connection end 54 on the side opposite to the fourth connection end 53 and the second connection end 55 are the front sides, and the outer walls of the fourth connection end 53 and the second connection end 55 on the side adjacent to the third connection end 52 and the first connection end 54 are the front sides.

[0053] When the spray plate 22 rotates as the rotor rod 2 rotates, at this time, the inclined nozzles 23 on the spray plate 22 first impact Figure 8The cooling oil sprayed from the oblique nozzle 23 passes over the first adapter end 54, and then the spray plate 22 rotates and the cooling oil sprayed from the oblique nozzle 23 passes over the first adapter end 54. Then, the cooling oil sprayed from the oblique nozzle 23 begins to spray the fourth adapter end 53 and the second adapter end 55. When the cooling oil sprayed from the oblique nozzle 23 sweeps along the arc-shaped outer wall connected to the fourth adapter end 53 and the second adapter end 55 and the fourth adapter end 53 and the second adapter end 55, the sprayed cooling oil sequentially sweeps along the back of the third adapter end 52. The sweeping sputtering is performed, so that the front and back sides of the third adapter end 52 are sprayed and cooled. Similarly, when the cooling oil sprayed by the oblique nozzle 23 passes over the second adapter end 55, the oblique nozzle 23 starts to spray the first end group and the second end group of the next group, and when the oblique nozzle 23 sprays the first end group and the second end group in the next group, the cooling oil sprayed by the third adapter end 52 and the first adapter end 54 in the next group will be splashed on the back side of the fourth adapter end 53 in the previous group. Therefore, during the process of the oblique nozzle 23 rotating and spraying, the front and back sides of the third adapter end 52 and the front and back sides of the fourth adapter end 53 in all the first end groups and the second end groups can be sprayed. The inclined nozzle 23 begins to spray onto the notch 43 on the inner probe rod 4. At this time, under the shielding of the notch 43, the cooling oil sprayed from the inclined nozzle 23 splashes onto the back sides of the first adapter end 54 and the second adapter end 55. Thus, the cooling oil is splashed by the direct spraying of the inclined nozzle 23 and the shielding of the notch 43, thereby dissipating the heat of the first adapter end 54 and the second adapter end 55 more comprehensively.

[0054] Therefore, the cooling oil sprayed through the oblique nozzle 23 fully impacts the adapter end, thereby avoiding the problem of poor heat dissipation caused by the limited impact surface of the adapter end due to the shielding between the adapter ends.

[0055] As the optimal embodiment provided by the present invention, it also includes an outer flat wire winding, which includes a third end group arranged in a circular array, and the third end group includes a fifth transfer terminal 5 and a sixth transfer terminal 51, and the fifth transfer terminal 5 and the sixth transfer terminal 51 are alternately distributed with the third transfer terminal 52 and the fourth transfer terminal 53.

[0056] Specifically, the outer flat wire winding is arranged in the winding slot 31, and the outer flat wire winding is adjacent to the middle flat wire winding. The outer flat wire winding is a further added flat wire winding layer, which further improves the power density and efficiency of the motor. The inner flat wire winding, the middle flat wire winding and the outer flat wire winding are sequentially distributed from inside to outside along the radial direction, such as Figure 6 shown.

[0057] When the spraying plate 22 rotates with the rotation of the rotor rod 2, the inclined spraying orifices 23 on the spraying plate 22 rotate and spray at this time. Then, the inclined spraying orifices 23 spray and cool the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55 in sequence. When the inclined spraying orifices 23 spray on the front outer walls of the fourth adapter end 53 and the second adapter end 55 adjacent to the first adapter end 54, the inclined spraying orifices 23 spray and cool the fourth adapter end 53 and the second adapter end 55 at this time. The cooling oil after spraying flows between the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55 under the limit and block of the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55, as Figure 8 shown. At this time, the flowing cooling oil flows to the fifth adapter end 5 respectively, and then the limit and guidance of the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55 are used to make the cooling oil after the inclined spraying orifices 23 spray act on the fifth adapter end 5, so as to achieve the cooling effect on the fifth adapter end 5. Similarly, when the inclined spraying orifices 23 cross the second adapter end 55 and spray on the first end group and the second end group of the next group, the cooling oil flowing between the fourth adapter end 53 and the second adapter end 55 in the first group and the third adapter end 52 and the first adapter end 54 in the second group will act on the sixth adapter end 51 at this time. Thus, the first end group and the second end group of multiple groups are used to guide the cooling oil, so that multiple third end groups are all subjected to the impact cooling of the cooling oil. Compared with the traditional stacking arrangement of adapter ends, through the staggered arrangement and splicing between the first end group, the second end group, and the third end group, the cooling oil sprayed by the inclined spraying orifices 23 can absorb the heat of the adapter ends more comprehensively, thereby improving the heat dissipation efficiency.

[0058] As another embodiment provided by the present invention, a partition member 33 arranged in a circular array is fixedly installed on the stator member 3, and the partition members 33 are respectively located on one side of the fifth adapter end 5 and the sixth adapter end 51 in the third end group, and the oil passage 32 is located between every two partition members 33.

[0059] Specifically, when the inclined nozzle 23 rotates and sprays, and sequentially sprays and cools the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55 in multiple first end groups and second end groups, the cooling oil splashed by the spraying flows again along between the third adapter end 52, the first adapter end 54, the fourth adapter end 53, and the second adapter end 55. At this time, the flowing cooling oil flows to the fifth adapter end 5 and the sixth adapter end 51 respectively, so as to cool the third end group. The cooling oil flowing along the fifth adapter end 5 and the sixth adapter end 51 flows into the oil passage 32 under the limiting and guiding of multiple partition members 33 at this time. Furthermore, the effect of guiding the cooling oil is achieved by using multiple partition members 33, avoiding the problem that the oil body flowing in the first oil chamber 12 is too disordered, resulting in turbulent flow before the oil body flows into the oil passage 32 and causing a reduction in the loss in the oil passage 32.

[0060] As another embodiment provided by the present invention, the partition members 33 are respectively attached to the fifth adapter end 5 and the sixth adapter end 51 in the third end group, and the partition members 33 are located on the oil spraying paths of multiple inclined nozzles 23.

[0061] Specifically, as Figure 8 shown, multiple partition members 33 are respectively attached to the fifth adapter end 5 and the sixth adapter end 51. Therefore, the heat dissipated by the fifth adapter end 5 and the sixth adapter end 51 can be transferred to the partition members 33 for heat dissipation. When the inclined nozzle 23 rotates and sprays, because the partition members 33 are located on the oil spraying paths of multiple inclined nozzles 23, as Figure 6 shown, at this time, the inclined nozzle 23 directly sprays on the partition members 33 to cool the partition members 33. At the same time, due to the high-speed cooling oil sprayed by the inclined nozzle 23 acting on the partition members 33, and in cooperation with the guiding of the partition members 33 for the cooling oil, the cooling oil can flow into the oil passage 32 more quickly. At this time, the flow rate in the oil passage 32 increases, and part of the cooling oil in the first oil chamber 12 is rectified and quickly flows into the oil passage 32 due to the increase in the flow rate at one end of the oil passage 32 where the partition members 33 are located, so as to achieve the rectifying effect on the cooling oil in the first oil chamber 12.

[0062] By using multiple partition members 33, the interference between the ports of multiple oil passages 32 in the first oil chamber 12 can be reduced, so that the flow of the cooling oil is more stable.

[0063] As another embodiment further provided by the present invention, a first blade 24 arranged in a circular array is fixedly installed on the outer wall of the spray plate 22 on the side opposite to the rotor member 26, and a curved surface portion is provided at one end of the fourth adapter end 53 located at the fifth adapter end 5.

[0064] Specifically, as Figure 7As shown, when the inclined nozzle 23 finishes spraying on the partition member 33 and starts spraying on the fourth adapter end 53, at this time, the inclined nozzle 23 starts spraying on the curved surface portion provided at one end of the fourth adapter end 53 located at the fifth adapter end 5. The sprayed cooling oil splashes on the curved surface portion and impacts on the outer wall of the fifth adapter end 5 adjacent to the sixth adapter end 51, thereby improving the heat dissipation effect of the fifth adapter end 5. As the inclined nozzle 23 rotates and sprays, when the cooling oil sprayed by the inclined nozzle 23 sweeps along the arc-shaped outer walls connecting the fourth adapter end 53 and the second adapter end 55 and the fourth adapter end 53 and the second adapter end 55, the sprayed cooling oil sequentially sweeps and splashes along the back surface of the third adapter end 52, as Figure 8 shown. At this time, part of the cooling oil will flow through the gap between the third adapter end 52 and the fifth adapter end 5, so that the fifth adapter end 5 can be in more comprehensive contact with the flowing cooling oil for heat dissipation.

[0065] Then, as the inclined nozzle 23 continues to rotate and spray, at this time, the inclined nozzle 23 starts spraying on the notch portion 43 on the inner probe rod 4. Under the shielding of the notch portion 43, the cooling oil sprayed by the inclined nozzle 23 splashes on the back surface of the first adapter end 54. Further, as the inclined nozzle 23 continues to rotate and spray, at this time, the inclined nozzle 23 starts to dock with the interface 41, so that the cooling oil is sprayed out from the plurality of drip holes 42 to dissipate heat from the stator member 3 and the rotor member 26 at the same time. The cooling oil flowing in the inner probe rod 4 can absorb and dissipate the heat of the stator member 3, and the cooling oil flowing in the oil passage 32 further dissipates the heat of the stator member 3, thereby improving the motor efficiency.

[0066] Further, during the process of the rotor rod 2 driving the spray plate 22 to rotate so that the plurality of inclined nozzles 23 rotate and spray, at this time, the first blade 24 rotates with the spray plate 22, thereby agitating the cooling oil in the first oil chamber 12, so that the cooling oil is deflected towards the oil passage 32, thereby accelerating the flow of the cooling oil. At the same time, the deflected cooling oil can contact the top surfaces of the fifth adapter end 5, the sixth adapter end 51, the third adapter end 52, the fourth adapter end 53, the first adapter end 54, and the second adapter end 55, thereby guiding the flow direction of the cooling oil and further accelerating the heat dissipation effect of the adapter end.

[0067] As the optimal embodiment further provided by the present invention, the spray plate 22 is fixedly installed on the outer wall on one side of the rotor member 26 with second blades 25 arranged in a circular array, and the stator member 3 is provided with winding grooves 31 arranged in a circular array. A gap oil passage 34 is provided between every two adjacent winding grooves 31 at the end of the stator member 3.

[0068] Specifically, as Figure 12As shown, when the inner flat wire winding, the middle flat wire winding, and the outer flat wire winding are respectively arranged in the winding slots 31, at this time, gap oil channels 34 are formed at the end of the stator member 3 between the inner flat wire winding, the middle flat wire winding, and the outer flat wire winding in every two adjacent winding slots 31, that is, gap oil channels 34 are formed at the end of the stator member 3 by the inner flat wire winding, the middle flat wire winding, and the outer flat wire winding in every two adjacent winding slots 31, and the gap oil channels 34 communicate with each other between every two partition members 33.

[0069] Therefore, when the oil pump pumps cooling oil into the oil inlet channel 21, and then the cooling oil is respectively ejected from a plurality of inclined nozzles 23 along the oil inlet channel 21, and then as the rotor rod 2 rotates in the stator member 3, at this time, the rotor rod 2 drives the spray plate 22 to rotate, and at this time, a plurality of inclined nozzles 23 sequentially pass over the first adapter end 54, the second adapter end 55, and the interface 41.

[0070] Furthermore, when the rotor rod 2 rotates, at this time as Figure 13 shown, the first blade 24 rotates with the spray plate 22, thereby agitating part of the cooling oil in the first oil chamber 12, so that the cooling oil is deflected towards the oil passage 32, thereby accelerating the flow of the cooling oil. At the same time, the deflected cooling oil can contact the top surfaces of the fifth adapter end 5, the sixth adapter end 51, the third adapter end 52, the fourth adapter end 53, the first adapter end 54, and the second adapter end 55, thereby guiding the flow direction of the cooling oil and further accelerating the heat dissipation effect of the adapter end.

[0071] Even further, the inclined nozzles 23 start to spray on the front surfaces of the third adapter end 52 and the first adapter end 54 to initially dissipate heat from the third adapter end 52 and the first adapter end 54. Then, as the inclined nozzles 23 continue to rotate and spray, the cooling oil sprayed by the inclined nozzles 23 detaches from the first adapter end 54 and starts to spray on the partition member 33. At this time, as Figure 6 shown, the partition member 33 absorbs part of the heat of the sixth adapter end 51 and dissipates heat under the spraying of the inclined nozzles 23. Then, under the continuous rotation and spraying of the inclined nozzles 23, the inclined nozzles 23 start to spray on the curved surface portion of the fourth adapter end 53 provided at one end of the fifth adapter end 5, and the sprayed cooling oil splashes on the curved surface portion and impacts on the outer wall of the fifth adapter end 5 adjacent to the sixth adapter end 51, thereby enhancing the heat dissipation effect of the fifth adapter end 5. As the inclined nozzles 23 rotate and spray, at this time, the cooling oil sprayed by the inclined nozzles 23 sweeps along the arc-shaped outer walls connecting the fourth adapter end 53 and the second adapter end 55 and the fourth adapter end 53 and the second adapter end 55 to impact and dissipate heat on the front surfaces of the fourth adapter end 53 and the second adapter end 55. After the sprayed cooling oil splashes on the fourth adapter end 53 and the second adapter end 55, it sequentially sweeps and impacts along the back surface of the third adapter end 52, as Figure 8As shown, at this time, part of the cooling oil will flow through the gap between the third adapter end 52 and the fifth adapter end 5, so that the fifth adapter end 5 can be in more comprehensive contact with the flowing cooling oil to dissipate heat.

[0072] Then, as the oblique nozzle 23 continues to rotate and spray, the oblique nozzle 23 begins to spray on the notch 43 on the inner probe rod 4, and the cooling oil sprayed by the oblique nozzle 23 splashes on the back of the first adapter end 54 under the shielding of the notch 43. Further, the oblique nozzle 23 continues to rotate and spray, and the oblique nozzle 23 begins to dock with the interface 41, so that the multiple drip holes 42 spray out cooling oil and dissipate heat to the stator part 3 and the rotor part 26 at the same time, and the cooling oil flowing in the inner probe rod 4 can absorb and dissipate the heat of the stator part 3, and the cooling oil flowing in the oil passage 32 further dissipates heat to the stator part 3, thereby improving the efficiency of the motor.

[0073] Furthermore, the oil sprayed into the gap cavity 27 along the multiple drip holes 42 is squeezed and discharged into the first oil cavity 12. At this time, the second blade 25 is driven to rotate under the rotation of the rotor rod 2. As the second blade 25 rotates, the cooling oil discharged from the gap cavity 27 is moved by the second blade 25 and quickly flows to the gap oil channel 34. The cooling oil flowing along the gap oil channel 34 absorbs part of the heat of the inner flat wire winding, the middle flat wire winding and the outer flat wire winding, thereby further dissipating the heat of the inner flat wire winding, the middle flat wire winding and the outer flat wire winding. Then, the cooling oil flowing along the gap oil channel 34 flows into the oil channel 32 under the guidance of the partition member 33. Then, the cooling oil in the oil passage 32 flows into the second oil chamber 13, and the flowing cooling oil dissipates heat for the inner layer flat wire winding, the middle layer flat wire winding and the outer layer flat wire winding in the second oil chamber 13. Then, the cooling oil in the second oil chamber 13 is discharged along the oil outlet 11 and circulated through the oil pump to dissipate heat.
