[0033] The following is a preferred embodiment of a motor with high efficiency in heat dissipation provided by the present invention that can solve the above technical problems.

[0034] Please refer to Figure 1 and Figure 2 ,in Figure 1 It is a schematic structural diagram of a preferred embodiment of a motor with high efficiency heat dissipation of the present invention. Figure 2 It is a schematic structural diagram of the cooling channel and spoiler assembly of the motor with high efficiency heat dissipation of the present invention.

[0035] In the figures, structurally similar elements are denoted by the same reference numerals.

[0036] The present invention provides a motor with high efficiency in heat dissipation, which comprises a housing 11, a stator assembly, a rotor assembly, and a spoiler assembly 13. The stator assembly is arranged in the housing 11, and the rotor assembly is arranged in the stator assembly.

[0037] Please refer to Figure 2 In this embodiment, a cooling channel is provided on the housing 11, and the cooling channel includes an axial channel 112 extending in the axial direction of the rotor assembly, and a circumferential channel 113 extending in the circumferential direction of the rotor assembly. Both ends of an axial channel 112 are connected to two adjacent axial channels 112 on both sides through a circumferential channel 113, that is, a Z-shaped extension is performed along the circumferential direction.

[0038] The axial channels 112 at both ends are connected to an adjacent axial channel 112 via a circumferential channel 113 at only one end, so that water inlets and outlets 111 can be provided on the axial channels 112 at both ends to facilitate water inflow and outflow for circulation and heat dissipation.

[0039] The axial end surface of the axial channel 112 is provided with an installation opening 114 for connecting the internal space and the external space, and the spoiler assembly 13 is connected to the axial channel 112 through the installation opening 114. In this way, the spoiler assembly can be processed separately, and the spoiler assembly can be assembled and adjusted according to needs, which has strong applicability. Compared with directly making the spoiler into the cooling channel, its manufacturing process is relatively simpler and the manufacturing cost is lower.

[0040] Please refer to Figure 3 In this embodiment, the spoiler assembly 13 includes an end portion 131, a connecting rod 132, and a spoiler 133. The end portion 131 is used to block the installation port 114. The connecting rod 132 is connected to the side of the end portion 131 close to the cooling channel. The two connecting rods 132 are arranged in parallel. A plurality of spoilers 133 are detachably connected between the two connecting rods 132. The connecting rod 132 and the spoiler 133 extend to the axial channel 112. The spoiler assembly allows the water flow layers to be well mixed with each other, thereby improving the heat dissipation and cooling effect of the motor.

[0041] Specifically, the spoiler 133 in this embodiment is connected to the card plate 1332 through the connecting block 1331. The card plate 1332 and the spoiler 133 are separated by a set distance to form a card slot. The set distance is less than or equal to the thickness of the connecting rod 132, so that the card slot can form a card connection with the connecting rod 132 with a certain interference force, and the connection is stable. The width of the card plate 1332 is less than or equal to the distance between the inner sides of the two connecting rods 132. The card plate 1332 is inserted into the distance interval between the inner sides of the two connecting rods 132, and then the card slot is connected to the connecting rod 132 by rotation.

[0042] The length of the clamping plate 1332 is greater than the distance between the outer side surfaces of the two connecting rods 132. A plurality of positioning recesses 1321 are provided on the outer side surface of the connecting rod 132. The plurality of positioning recesses 1321 are distributed along the axial direction of the connecting rod 132. Both ends of the clamping plate 1332 are provided with positioning convex bumps 1334 for positioning and cooperating with the positioning recesses 1321. Through the cooperation between the positioning convex bumps 1334 and the positioning recesses 1321, the spoiler 133 is stably connected to the connecting rod 132.

[0043] Among them, when the clamping plate 1332 and the connecting rod 132 form a certain connection and the positioning convex bump 1334 does not form a match with the positioning concave portion 1321, the clamping plate 1332 can be moved on the connecting rod 132 to adjust the position of the final spoiler 133 connected to the connecting rod 132.

[0044] Please refer to Figure 4 In this embodiment, the connecting rod 132 includes a fixed rod segment 21 and a plurality of movable rod segments 22 , and the fixed rod segment 21 is fixedly connected to the end portion 131 .

[0045] The end of the fixed rod segment 21 away from the end portion 131 is provided with a first matching structure, the first matching structure includes a first concave step 231 provided at one end of the fixed rod segment 21, and a positioning groove 232 provided in the first concave step 231. Along the width direction of the fixed rod segment 21, one end of the first concave step 231 penetrates the fixed rod segment 21, and the other end is provided with a stopper 233, and the positioning groove 232 penetrates the stopper 233;

[0046] The two ends of the movable rod segment 22 are respectively provided with a first matching structure and a second matching structure. The second matching structure includes a second recessed step 241 arranged at one end of the movable rod segment 22, and a positioning block 242 arranged in the second recessed step 241. The positioning block 242 is used for positioning and matching with the positioning groove 232. One end of the second recessed step 241 is provided with a notch 243 that matches with the stop block 233. The positioning block 242 extends into the notch 243. The extended part of the positioning block 242 can verify that the positioning groove 232 is inserted into the stop block 233, so that the first matching structure and the second matching structure form a preliminary connection match.

[0047] One end of the fixed rod segment 21 is connected to the second matching structure of the movable rod segment 22 through the first matching structure, and multiple movable rod segments 22 can also be connected through the first matching structure and the second matching structure, so that the spoiler component 13 can adjust its size through assembly or disassembly, can be suitable for different motors, and has high compatibility.

[0048] Furthermore, when the first matching structure and the second matching structure are matched, the thickness is equal to the thickness of the fixed rod segment 21 and the thickness of the movable rod segment 22. The blocks 233 of the two connecting rods 132 are located at one end away from each other. The first matching structure and the second matching structure are clamped in the slot of the spoiler 133. The connecting block 1331 is located on the side of the first recessed step 231 away from the block 233. The connecting block 1331 blocks the disassembly and separation direction of the first matching structure and the second matching structure, thereby further enhancing the stability of the matching connection between the first matching structure and the second matching structure.

[0049] Please refer to Figure 3 In this embodiment, a plurality of through grooves 1333 are provided through one end of the spoiler 133 away from the connecting rod 132, and the through grooves 1333 of adjacent spoilers 133 on the connecting rod 132 are staggered, so that the water flow mixing at each level is better in heat conduction and heat dissipation effect is better.

[0050] Please refer to Figure 5 An optional implementation structure of the spoiler 133 can also be that the two spoilers 133 are respectively connected to the two ends of the connecting block 1331, the card plate 1332 is connected to the connecting block 1331, and the card plate 1332 is located between the two spoilers 133, and the two sides of the card plate 1332 correspond to each other and form a card groove at a set distance between the two spoilers 133.

[0051] Furthermore, the two spoilers 133 are both provided with a plurality of through slots 1333, and the through slots 1333 on the two spoilers 133 are staggered, and all spoilers have the same structure, which is convenient for manufacturing. The two adjacent spoiler structures on the connecting rod 132 can be reversely arranged so that the through slots 1333 of the two adjacent spoiler structures are staggered, thereby improving the mixed heat conduction effect of the water flow.

[0052] In this way, spoilers with through grooves 1333 are provided at both the upper and lower ends of the connecting rod, so that the water flow mixing and heat conduction are better and the heat dissipation effect is good.

[0053] Please refer to Figure 3 In this embodiment, the end portion 131 includes an end body and a flange plate 1312 arranged on the outer circumferential side of the end body. A sealing ring is arranged along the circumference of the end body, and the sealing ring is arranged in a ring groove 1311 of the end body. The end body is interference-fitted with the mounting port 114 through the sealing ring to achieve stable connection and sealing. The outer diameter of the flange plate 1312 is larger than the inner diameter of the mounting port 114. Grooves 1313 that are easy to disassemble are arranged on both sides of the flange plate 1312 to facilitate disassembly and assembly.

[0054] Please refer to Figure 2In this embodiment, a plurality of mounting openings 114 are provided on the same end surface of the housing 11, and the motor with high efficiency heat dissipation further comprises an end cover plate 12, which is fixedly connected to the housing 11 by screws, and the end cover plate 12 presses the spoiler assembly 13 into the mounting opening 114, so that the spoiler assembly 13 and the housing 11 are stably assembled. A receiving groove for accommodating the flange plate 1312 may be provided on the end cover plate 12, so that the end cover plate 12 and the housing 11 are tightly assembled, and the end cover plate 12 and the flange plate 1312 are stably matched.

And compared with directly placing the spoiler in the cooling channel, its manufacturing process is relatively simpler.

[0056] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
