Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] As described in the background section, motors generate heat during operation. Currently, liquid cooling is commonly used for heat dissipation. This involves the liquid circulating through coolant channels within the motor housing. The heat generated during motor operation is first transferred to the housing, and then carried away by the circulating coolant. However, existing coolant channels are generally folded labyrinth-shaped, with many twists and turns, resulting in high manufacturing costs. Furthermore, they lead to long coolant flow paths, significant pressure loss, and slow flow rates, resulting in low heat dissipation efficiency.

[0040] Based on this, please refer to Figures 1-4 The present invention provides a motor base 100 and a motor, which can effectively improve the aforementioned technical problems. Specifically, it can shorten the coolant flow path, reduce liquid flow pressure loss, improve coolant flow rate and heat dissipation efficiency, and reduce processing costs. The motor base 100 and the motor will be described in detail below.

[0041] This embodiment provides an electric motor, which includes a motor frame 100 and a motor body. The motor body generates heat during operation, and the motor frame 100 can dissipate heat from the motor body.

[0042] For details, please refer to Figures 1-4 , Figure 1 This is a first-view structural schematic diagram of the motor base 100 provided in this embodiment. Figure 2 This is a second-view structural schematic diagram of the motor base 100 provided in this embodiment. Figure 3 This is a first sectional view of the motor base 100 provided in this embodiment. Figure 4 This is a second sectional view of the motor base 100 provided in this embodiment, combined with... Figures 1-4 The motor base 100 includes a base housing 10 and an annular sealing plate 20. The base housing 10 has a liquid inlet 11, a liquid outlet 12 and an annular groove 13. The liquid inlet 11 and the liquid outlet 12 are spaced apart and are connected to the annular groove 13. The annular sealing plate 20 is connected to the base housing 10 and seals the annular groove 13 to form a coolant channel 30 together with the annular groove 13. The coolant channel 30 is connected to both the liquid inlet 11 and the liquid outlet 12.

[0043] As is easily understood, the coolant channel 30 formed by the base housing 10 and the annular sealing plate 20 is a complete and interconnected chamber with unobstructed internal channels and no tortuous or bent structures. Compared with the existing folded labyrinth-type channels, it can shorten the coolant flow path, reduce the loss of liquid flow pressure, thereby improving the coolant flow rate and heat dissipation efficiency, and reducing processing costs.

[0044] It should be noted that the annular sealing plate 20 and the base housing 10 can be welded together to seal the annular groove 13. During the welding process, the annular sealing plate 20 can first be positioned on the base housing 10 through the stop, and then welded on the outside. Finally, when machining the connecting stops at both ends, no weld is machined, so as not to affect the sealing performance of the coolant passage 30.

[0045] In this embodiment, the inlet 11 and outlet 12 are arranged opposite to each other, and the centerline of the inlet 11 coincides with the centerline of the outlet 12. That is, the inlet 11 and outlet 12 are coaxially arranged. When the base housing 10 is circular, it can also be understood that the center of the inlet 11, the center of the base housing 10, and the center of the outlet 12 are on the same straight line. In this way, the circulation path of the coolant in and out of the coolant channel 30 can be increased, thereby improving the cooling and heat dissipation effect.

[0046] Furthermore, the motor base 100 also includes a temperature sensor 40, which is disposed in the base housing 10 and located between the liquid inlet 11 and the liquid outlet 12. By setting up the temperature sensor 40, it can come into contact with the coolant and monitor the coolant temperature in real time through the temperature probe. This allows for real-time adjustment of the coolant flow rate and temperature according to actual conditions, thereby better dissipating heat from the motor body and improving the heat dissipation effect.

[0047] In order to improve the accuracy of temperature monitoring and further improve the heat dissipation effect, in this embodiment, the distance between the liquid inlet 11 and the thermometer 40 is the same as the distance between the liquid outlet 12 and the thermometer 40. That is, the thermometer 40 is specifically located in the middle of the liquid inlet 11 and the liquid outlet 12.

[0048] It should be noted that the thermometer 40 and the base housing 10 can be connected by threads, which can facilitate installation and disassembly. In order to improve the sealing, the connection between the thermometer 40 and the base housing 10 can also be glued.

[0049] It is understandable that an external coolant supply device is required for cooling the motor. This device is connected to the motor housing 10 and simultaneously communicates with both the inlet 11 and the outlet 12 to allow the coolant to circulate within the coolant channel 30. Therefore, to facilitate the connection of the external coolant supply device, in this embodiment, the motor housing 100 also includes an inlet connector and an outlet connector (not shown in the figure). The inlet connector is located at the inlet 11, and the outlet connector is located at the outlet 12.

[0050] Of course, for ease of installation and disassembly, the inlet connector and inlet port 11 can also be connected by threads, as can the outlet connector and outlet port 12. Furthermore, to ensure a tight seal after connection, the connection between the inlet connector and inlet port 11, and the connection between the outlet connector and outlet port 12, can also be glued together.

[0051] To further facilitate the connection between the coolant supply device and the base housing 10, or to facilitate the connection between the inlet connector and the inlet port 11, and the outlet connector and the outlet port 12, in this embodiment, the motor base 100 further includes an inlet protrusion 61, which is disposed on the base housing 10 and has an inlet port 11; similarly, the motor base 100 also includes an outlet protrusion 62, which is disposed on the base housing 10 and has an outlet port 12.

[0052] It is easy to understand that by setting the liquid inlet protrusion 61 and the liquid outlet protrusion 62, the overall structural strength of the motor base 100 can be improved to a certain extent, ensuring the stability of the motor during operation.

[0053] Please continue to combine Figures 1-3 In order to facilitate the connection and fixation of the motor base 100 with other components, in this embodiment, the motor base 100 also includes a plurality of mounting protrusions 50, which are arranged around the base housing 10, and each mounting protrusion 50 is provided with a mounting hole 51.

[0054] Similarly, by setting multiple mounting protrusions 50, the overall structural strength of the motor housing 100 can be improved to a certain extent. In addition, the multiple mounting protrusions 50 are arranged around the outer peripheral wall of the housing 10, and the mounting holes 51 will not interfere with the coolant passage 30, thereby ensuring that the normal flow of coolant is not obstructed and improving the heat dissipation effect.

[0055] It should be noted that the specific distribution of the liquid inlet protrusion 61, the liquid outlet protrusion 62, and the multiple mounting protrusions 50 needs to be adjusted according to the actual situation. For example, in this embodiment, the liquid inlet protrusion 61, the liquid outlet protrusion 62, and the multiple mounting protrusions 50 are spaced apart and arranged around the outer peripheral wall of the base housing 10, and the spacing between the liquid inlet protrusion 61, the liquid outlet protrusion 62, and the multiple mounting protrusions 50 is equal, thereby further improving the overall structural strength of the motor base 100 and ensuring the stability of the motor during operation.

[0056] In summary, the embodiments of this utility model provide a motor base 100 and a motor. The motor base 100 includes a base housing 10 and an annular sealing plate 20. The base housing 10 has a liquid inlet 11, a liquid outlet 12, and an annular groove 13. The liquid inlet 11 and the liquid outlet 12 are spaced apart, and both the liquid inlet 11 and the liquid outlet 12 are connected to the annular groove 13. The annular sealing plate 20 is connected to the base housing 10 and seals the annular groove 13, forming a coolant channel 30 together with the annular groove 13. The coolant channel 30 is simultaneously connected to both the liquid inlet 11 and the liquid outlet 12. It is easy to understand that the coolant channel 30 formed by the base housing 10 and the annular sealing plate 20 is a complete and connected chamber with unobstructed internal channels and no tortuous or bent structures. Compared with the existing folded labyrinth-type channels, it can shorten the coolant flow path, reduce the loss of liquid flow pressure, thereby improving the coolant flow rate and heat dissipation efficiency, and reducing processing costs.

[0057] The motor includes a motor housing 100, which has all the functions and benefits of the motor housing 100.
