Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The terms "first," "second," and the like in the description and in the claims, are not used for any order, quantity, or importance, but are used for distinguishing between different elements. Likewise, the terms "a," "an," or "the" and similar terms do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items.
Fig. 1 is a disassembled view of an electric machine 1 provided in accordance with at least one embodiment of the present disclosure.
As shown in fig. 1, the motor 1 includes a housing 2, a stator 3 accommodated in the housing 2, the stator 3 having a first end and a second end in a motor axis direction, and a cooling ring 4 provided at the first end and the second end of the stator 3, and the cooling ring 4 surrounding stator coils 32 at both ends of the stator 3. The cooling ring is an annular structure, typically made of a metallic material, with spray holes, for example, provided thereon, which are constantly rotating when the motor is in operation, while the spray holes constantly spray out a cooling medium (e.g., oil) which is applied to the stator packages at the first and second ends. Thus, the temperature of the motor is effectively reduced, and the normal operation of the motor is ensured. The stator 3 is provided with a first flow path rib 31, the first flow path rib 31 is a strip-shaped protrusion which is axially provided along an outer surface of the stator 3 and is configured to extend uninterrupted in an axial direction to be in contact with at least a portion of the flow blocking rib 41, and the first flow path rib 31 is integrally formed with the stator 3. In this embodiment, the first flow path ribs 31 are unchanged in shape in the axial direction, so that only one type of stator lamination is required, whereby the model cost can be saved. A circumferentially extending flow blocking rib 41 is provided at a position of the cooling ring 4 close to the stator end and a circumferentially extending baffle 42 is provided at a position of the cooling ring 4 remote from the stator end, the flow blocking rib 41 having an opening 5. The spray holes, which are outlets 12 for the cooling medium, are circumferentially spaced on the cooling ring 4 between the flow ribs 41 and the baffle plate 42. The housing 2 is provided with an inlet 23 for receiving an external cooling medium. The assembled structure of the motor shown in fig. 1 is shown in fig. 5.
The above-described motor 1 includes a cooling system provided according to at least one embodiment of the present disclosure, and the cooling system provided by the embodiment of the present disclosure is specifically described below with reference to fig. 2 to 6.
As shown in fig. 2 and 6, the cooling system includes an axial flow passage 10 and a cooling ring flow passage 20. The axial flow channel 10 comprises an inlet 11 for receiving an external cooling medium, the inlet 11 being in fluid communication with an inlet 23 on the housing 2, the axial flow channel 10 being located between the first and second end portions of the stator 3 and being formed by the inner wall of the housing and the outer wall of the stator. The cooling ring flow passage 20 is located on the outer surface of the cooling ring 4 and is formed by the inner wall of the housing and the outer surface of the cooling ring. The cooling ring flow channels 20 are in fluid communication with the axial flow channels 10 such that the cooling medium alternately flows through the axial flow channels 10 and the cooling ring flow channels 20 at either end, and then flows out of the axial flow channels 10 to the outlets 12 on the cooling ring flow channels 20 at both ends.
Specifically, the cooling ring flow passage 20 includes a first circumferential flow passage 21 near the stator end portion and a second circumferential flow passage 22 far from the stator end portion, the first circumferential flow passage 21 is formed by a flow blocking rib 41, the second circumferential flow passage 22 is formed by the flow blocking rib 41 and a baffle 42, and the outlet 12 of the cooling ring flow passage 20 is provided on the second circumferential flow passage 22. The first circumferential flow channel 21 is in fluid communication with the axial flow channel 10 such that the cooling medium alternately flows through the axial flow channel 10 and the first circumferential flow channel 21 at either end, and then flows out of the axial flow channel 10 into the second circumferential flow channel 22 via the opening portion 5 of the flow blocking rib 41.
In some embodiments of the present disclosure, the axial flow channel includes a second flow channel rib and a third flow channel rib in addition to the first flow channel rib. As shown in fig. 3, the second flow path rib 201 and the third flow path rib 202 are provided on the inner wall of the housing, and the third flow path rib 202 is adjacent to the inlet 11. Grooves 203 are formed between the second flow channel ribs 201, and the grooves 203 are used for being clamped with the first flow channel ribs 31. The third flow path rib 202 is configured to extend in the axial direction and has an opening 6 so that the cooling medium flows out from the axial flow path 10 to the cooling ring flow paths 20 at both ends. The use of the third flow path rib 202 having the opening portions 6 can avoid the use of different types of stator laminations because if the opening portions are provided on the first flow path rib 31, different types of stator laminations need to be used, thereby increasing costs. For example, in the present embodiment, the opening 6 is provided at the intermediate position of the third flow path rib 202. Providing the opening 6 at the intermediate position of the third flow path rib 202 makes it possible to make the cooling medium flow evenly to both ends of the stator, so that the cooling effect is uniform. The opening 6 may be provided at another position, and the present disclosure is not limited thereto.
In some embodiments of the present disclosure, the cooling ring is provided with protrusions including first protrusions provided on the flow blocking ribs and/or second protrusions provided on the baffles. For example, as shown in fig. 4, a first protrusion 411 is provided on the flow blocking rib 41, a second protrusion 421 is provided on the baffle 41, and the first protrusion 411 and the second protrusion 421 are used for being in snap fit with the groove 203, thereby fixing the cooling ring 4. Other specific structures of the cooling ring 4 have been described above and will not be described here again. It should be noted that the nozzle holes on the cooling ring 4 are only an example, and other structures for passing the cooling medium are also possible, which is not limited in this disclosure.
In some embodiments of the present disclosure, the second and third flow channel ribs 201, 202 are interference fit with the outer surface of the stator 3, and the sides of the first flow channel rib 31 are interference fit with the sides of the slot 203, thereby preventing the stator 3 from axially moving within the housing 2. Further, the first flow path rib 31 engages with the groove 203, and the stator 3 is prevented from rotating circumferentially in the housing 2.
Fig. 6 is a schematic diagram of a flow path of a cooling system provided in accordance with at least one embodiment of the present disclosure.
For example, in the assembled state of the motor, the cooling system includes N axial flow passages 10 (1 st axial flow passage, 2 nd axial flow passage,..the nth axial flow passage), N being a positive integer greater than 1. The outer surface of the electronic core is divided into the 1 st to nth axial flow passages in order by the first, second and third flow passage ribs 31, 201 and 202. The cooling medium first enters the 1 st axial flow passage through the inlet 11. The flow blocking rib 41 cooperates with the structure of the first flow path rib 31 to make the cooling medium flow in a serpentine shape and prevent the cooling medium from flowing toward the outlet 12 when flowing in the 1 st to N-1 st axial flow paths.
As shown in fig. 6, the cooling medium first flows into the 1 st axial flow passage 10 on the outer surface of the stator core through the inlet 11, and then flows axially toward one end of the stator. The first circumferential flow channel 21 is in fluid communication with the axial flow channel 10, and the cooling medium can alternately flow through the axial flow channel 10 and the first circumferential flow channel 21 at any end, flow in a serpentine shape on the surface of the stator core until flowing into the N-1 th axial flow channel, then flow from the N-1 th axial flow channel into the N-th axial flow channel through the opening part 6 of the third flow channel rib 202, flow out to the two ends of the stator respectively in the N-th axial flow channel, flow into the second circumferential flow channel 22 through the opening part 5 of the flow blocking rib 41, and finally flow out from the outlet 12 of the second circumferential flow channel 22 to cool the stator coil 32 at the first end and the second end.
The flow blocking rib 41 can prevent the cooling medium from flowing to the second circumferential flow passage 22 so that the entire cooling medium first cools the surface of the stator 3. After approximately one revolution of the cooling medium around the stator surface, it enters the second circumferential flow channel 22. Such a flow path allows the cooling medium to be used to cool the stator surface first, and then cool the stator coil 32 through the outlet 12, thereby improving the cooling effect.
At least one embodiment of the present disclosure provides a cooling system formed by the specific structure of the motor provided by the embodiments of the present disclosure, which has the advantages of the motor as described above.
