[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Reference Appendix Figure 1 As shown in Figure 4, this utility model proposes a novel water-cooled motor device, which includes a housing 10, a first end cover 11, a second end cover 12, a liquid inlet 21, a liquid outlet 22, and a motor component 13.

[0019] The inside of the shell 10 forms a space for accommodating the motor components 13, the first end cover 11 and the second end cover 12 are fixedly arranged on both sides of the shell 10 respectively, the liquid inlet 21 is arranged on the first end cover 11, and the liquid outlet 22 is arranged on the second end cover 12. In the vertical direction of the shell 10, the liquid inlet 21 is located above the liquid outlet 22. The first end cover 11 and the second end cover 12 are connected to the outer wall of the shell 10 by fastening bolts respectively.

[0020] The inside of the first end cover 11 is provided with a first flow guide cavity 111. A plurality of flow guide cavities are arranged in the circumferential direction of the first end cover 11. The plurality of first flow guide cavities 111 are independently arranged. The inside of the second end cover 12 is provided with a second flow guide cavity 121. A plurality of flow guide cavities are arranged in the circumferential direction of the second end cover 12. The plurality of second flow guide cavities 121 are independently arranged. The first flow guide cavity 111 and the second flow guide cavity 121 are both hollow. The partition column 14 is formed between adjacent first flow guide cavities 111 and between adjacent second flow guide cavities 121.

[0021] The shell 10 is provided with a heat exchange flow channel 101. A plurality of heat exchange flow channels 101 are arranged in the circumferential direction of the shell 10. The heat exchange flow channel 101 extends along the axis direction of the shell 10. One end of the heat exchange flow channel 101 along the axis direction corresponds to the first flow guide cavity 111 and is connected thereto. The other end of the heat exchange flow channel 101 along the axis direction corresponds to the second flow guide cavity 121 and is connected thereto. The first flow guide cavity 111, the heat exchange flow channel 101 and the second flow guide cavity 121 connected by the first flow guide cavity 111, the heat exchange flow channel 101 and the second flow guide cavity 121 form a liquid flow channel. The liquid flows into the liquid flow channel through the liquid inlet 21 and is transported outward from the liquid outlet 22 through the liquid flow channel.

[0022] The first flow guide cavity 111 is located in the first end cover 11. The purpose of arranging a larger flow area is to effectively reduce the flow rate when the water cooling liquid flows from the liquid inlet 21, so as to avoid the sudden drop in pressure and flow state disorder caused by too fast flow rate at the inlet. In this way, the water cooling liquid can be uniformly dispersed into the subsequent flow channel, reducing the generation of local turbulent flow and vortex flow, and ensuring the stability and uniformity of the cooling process.

[0023] The second flow guide cavity 121 is located in the second end cover 12, and the flow area is smaller than that of the first flow guide cavity 111. In the process of transporting the water cooling liquid, it mainly plays a role in converging and regularizing the water flow. After passing through the heat exchange flow channel 101, the flow rate and flow state of the water cooling liquid change. The second flow guide cavity 121 can converge and adjust the flow rate to adapt to the drainage requirements of the liquid outlet 22, so as to prevent impact and noise caused by uneven or too fast flow rate when discharging.

[0024] The first flow guide cavity 111, the heat exchange flow channel 101 and the second flow guide cavity 121 are sequentially communicated to form a complete liquid flow channel. The large flow area of the first flow guide cavity 111 provides guarantee for initial smooth conveying, the heat exchange flow channel 101 realizes heat exchange with the motor component 13, and the second flow guide cavity 121 is used for flow state arrangement before flowing out. The design that the flow areas of the three are sequentially decreased changes the flow speed of the water cooling liquid in the whole flow channel, which not only ensures sufficient residence time for heat exchange in the heat exchange flow channel 101, but also enables the water cooling liquid to be smoothly discharged at the outlet, thereby improving the conveying efficiency and cooling efficiency of the water cooling liquid in the flow channel and optimizing the operation performance of the water cooling system.

[0025] The flow area of the first flow guide cavity 111 is larger than that of the second flow guide cavity 121, and the flow area of the second flow guide cavity 121 is larger than that of the heat exchange flow channel 101.

[0026] Specifically, the flow area refers to the effective cross-sectional area through which the liquid can pass in the flow channel. For the first flow guide cavity 111, the second flow guide cavity 121 and the heat exchange flow channel 101, the flow area determines the flow rate and flow speed of the liquid. It is usually measured perpendicular to the direction of liquid flow, such as the circular cross section of the flow guide cavity or the heat exchange flow channel 101, and the area is the cross-sectional area of the circle. This definition facilitates the understanding of the flow of the liquid in each part of the flow channel by the technical personnel, and through reasonable design of the flow area, such as the size difference in the present scheme, the flow characteristics of the liquid are controlled to achieve the ideal water cooling effect.

[0027] The first flow guide cavity 111 and the second flow guide cavity 121 play an important role in improving the water cooling performance. The first flow guide cavity 111 is arranged in the first end cover 11, and the flow area thereof is relatively large, which aims to make the cooling liquid enter the liquid flow channel system in a relatively stable and uniform state. The large flow area can reduce the flow speed of the cooling liquid, reduce the local pressure loss caused by the too fast flow speed, and enable the cooling liquid to more fully exchange and diffuse heat in the end cover area, thereby laying a good foundation for subsequent cooling circulation in the whole motor equipment.

[0028] The second flow guide cavity 121 is located in the second end cover 12, and the flow area thereof is smaller than that of the first flow guide cavity 111 but larger than that of the heat exchange flow channel 101. It plays a role of buffering and transition, and when the cooling liquid flows out from the heat exchange flow channel 101, it can be gathered and arranged to a certain extent, so that the flow speed of the cooling liquid is further adjusted to flow to the liquid outlet 22 for smooth discharge. At the same time, the second flow guide cavity 121 can also continue to absorb the heat transferred from the motor component 13 to the end cover after the cooling liquid flows out from the heat exchange flow channel 101, thereby enhancing the cooling effect.

[0029] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still be modified to the technical solutions recorded in the foregoing examples, or part of the technical features are replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
