[0044] As mentioned in the background technology: the heat exchange in the motor directly affects the performance of the motor. In order to prevent the heat inside the motor from being dissipated in time, it is usually necessary to add a cooling water jacket on the outside of the motor to cool the motor.

[0045] There are currently four main types of common cooling water jackets, namely spiral water jacket, axial water jacket, circumferential water jacket and semi-spiral water jacket. The cooling water jacket includes a shell, a water inlet and a water outlet. There is a cooling channel in the shell, and the water inlet and water outlet are respectively connected to the two ends of the cooling channel.

[0046] However, the water inlet and outlet are usually located at both ends of the cooling water jacket or on the same side of the cooling water jacket, which limits the layout of the cooling water jacket.

[0047] In order to solve the technical problems raised above, the present application provides a cooling water jacket, a motor and a vehicle, wherein the cooling water jacket is used to be installed on the motor, the cooling water jacket includes a shell, a water inlet and a water outlet, the shell is arranged on the outside of the motor, and a cooling channel is provided in the shell, the cooling channel includes a plurality of first channels and a plurality of second channels, the first channels are arranged along the axial direction of the shell, the plurality of first channels are connected in sequence to form an axial channel, the second channels are arranged along the circumference of the shell, the plurality of second channels are connected in sequence to form a circumferential channel, and the axial channel is connected to the circumferential channel; the water inlet and the water outlet are arranged on the shell, the water inlet is connected to the axial channel, and the water outlet is connected to the circumferential channel; the axial channel and the circumferential channel are spliced ​​to form a cooling channel that completely surrounds the shell, the starting position of the axial channel and the end position of the circumferential channel can be located at any two different positions of the shell, so that the layout positions of the water inlet and the water outlet can be located at any two different positions of the shell, thereby diversifying the layout methods of the water inlet and the water outlet in the cooling water jacket and increasing the scope of application of the cooling water jacket.

[0048] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0049] refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application discloses a cooling water jacket for installation on a motor, the cooling water jacket comprising a shell 100 , a water inlet 300 and a water outlet 400 .

[0050] The housing 100 is sleeved on the outside of the motor.

[0051] A cooling channel 200 is provided in the shell 100, and the cooling channel 200 includes a plurality of first channels 210 and a plurality of second channels 220. The first channels 210 are arranged along the axial direction of the shell 100, and the plurality of first channels 210 are connected in sequence to form an axial channel. The second channels 220 are arranged along the circumference of the shell 100, and the plurality of second channels 220 are connected in sequence to form a circumferential channel. The axial channels are connected to the circumferential channels.

[0052] The water inlet 300 and the water outlet 400 are provided on the housing 100 . The water inlet 300 is communicated with the axial channel, and the water outlet 400 is communicated with the circumferential channel.

[0053] The axial direction of the shell 100 refers to the direction of the shell 100 along its axial direction, which may be the direction of the shell 100 along its length; the circumferential direction of the shell 100 refers to the direction around the shell 100.

[0054] For example, the first channel 210 and the second channel 220 may be pipeline structures.

[0055] Exemplarily, the axial channel and the circumferential channel are connected to completely cover the interior of the shell 100. Since the axial channel is arranged along the axial direction of the shell 100 and the circumferential channel is arranged along the circumference of the shell 100, the arrangement of the axial channel and the circumferential channel can be various, which means that the starting position of the axial channel and the end position of the circumferential channel can be located at any two different positions of the shell 100. For example, the starting position of the axial channel is located on one side of the shell 100, and the end position of the axial channel is located in the middle of the shell 100.

[0056] By adopting the above technical solution, the axial channel and the circumferential channel are spliced ​​together to form a cooling channel 200 that completely surrounds the shell 100. The starting position of the axial channel and the end position of the circumferential channel can be located at any two different positions of the shell 100, so that the layout positions of the water inlet 300 and the water outlet 400 can be located at any two different positions of the shell 100, thereby diversifying the layout of the water inlet 300 and the water outlet 400 in the cooling water jacket, thereby increasing the scope of application of the cooling water jacket.

[0057] In some embodiments, the housing 100 includes an outer shell 110 and an inner shell 120 . The outer shell 110 is sleeved on the outside of the inner shell 120 , and there is a gap between the outer shell 110 and the inner shell 120 . The water inlet 300 and the water outlet 400 are both provided on the outer shell 110 .

[0058] Exemplarily, the outer shell 110 is cylindrical, and the inner shell 120 is also cylindrical. The inner diameter of the outer shell 110 is larger than the inner diameter of the inner shell 120, so that when the outer shell 110 is sleeved on the inner shell 120, there is a gap between the outer shell 110 and the inner shell 120.

[0059] For example, the outer shell 110 and the inner shell 120 can be bent and formed integrally into the housing 100 .

[0060] By adopting the above technical solution, the housing 100 is formed by providing the outer shell 110 and the inner shell 120 , thereby reducing the production cost of the housing 100 .

[0061] In some embodiments, the housing 100 further includes a plurality of first ribs 130 and a plurality of second ribs 140 , and both the first ribs 130 and the second ribs 140 are disposed between the outer shell 110 and the inner shell 120 .

[0062] The first ribs 130 are arranged along the axial direction of the housing 110 , and there is a gap between two adjacent first ribs 130 to form a first channel 210 .

[0063] The second ribs 140 are arranged along the circumference of the housing 110 , with a gap between two adjacent second ribs 140 to form a second channel 220 .

[0064] Illustratively, the first rib 130 and the second rib 140 abut against the inner circumferential wall of the outer shell 110 and the outer circumferential wall of the inner shell 120 , respectively.

[0065] Exemplarily, the first rib 130 and the second rib 140 are glued or welded to one of the outer shell 110 and the inner shell 120 .

[0066] By adopting the above technical solution and providing the first ribs 130 and the second ribs 140 , the first channel 210 and the second channel 220 are formed in the housing 100 , thereby reducing the production cost of the cooling water jacket.

[0067] In some embodiments, the first rib 130 and the second rib 140 are integrally formed with one of the outer shell 110 and the inner shell 120 .

[0068] Exemplarily, the first rib 130 and the second rib 140 are both integrally formed with the outer peripheral wall of the inner shell 120 .

[0069] By adopting the above technical solution, the production cost of the cooling water jacket is reduced.

[0070] In some embodiments, the outer shell 110 and the inner shell 120 are connected by friction welding.

[0071] By adopting the above technical solution, the outer shell 110 and the inner shell 120 are connected by friction welding, which not only ensures the stability of the outer shell 110 and the inner shell 120 after being connected, but also ensures the sealing of the outer shell 110 and the inner shell 120 after being connected, thereby avoiding leakage of the cooling medium in the shell 100.

[0072] In some embodiments, the cooling water jacket further includes a water inlet connector 500 , which is connected to the water inlet 300 and extends to the outside of the housing 110 .

[0073] Illustratively, one end of the water inlet connector 500 facing away from the housing 110 has an internal thread, so that the water inlet connector 500 can be connected to a water inlet pipe of the cooling medium.

[0074] By adopting the above technical solution and providing the water inlet joint 500, it is convenient to connect the cooling water jacket with the water inlet end of the cooling medium.

[0075] In some embodiments, the cooling water jacket further includes a water outlet connector 600 , which is connected to the water outlet 400 and extends to the outside of the housing 110 .

[0076] Illustratively, one end of the water outlet connector 600 facing away from the housing 110 has an internal thread, so that the water outlet connector 600 can be connected to a return pipe of the cooling medium.

[0077] By adopting the above technical solution and providing the water outlet joint 600, it is convenient to connect the cooling water jacket with the return water end of the cooling medium.

[0078] In some embodiments, the housing 100 further includes a plurality of heat dissipation bosses 700 , which are disposed on the outer peripheral wall of the inner housing 120 .

[0079] By adopting the above technical solution and providing the heat dissipation boss 700, the contact area between the cooling water jacket and the cooling medium is increased, the heat transfer efficiency between the cooling water jacket and the cooling medium is improved, and thus the heat dissipation efficiency of the cooling water jacket to the motor is improved.

[0080] In some embodiments, the heat dissipation boss 700 is an arc-shaped protrusion.

[0081] Exemplarily, the heat dissipation boss 700 is a hemispherical protrusion.

[0082] By adopting the above technical solution, the heat dissipation boss 700 is set as an arc-shaped protrusion, which minimizes the resistance of the arc-shaped boss to the flow of cooling medium, thereby ensuring the heat dissipation efficiency of the cooling water jacket to the motor.

[0083] An embodiment of the present application further discloses a motor, comprising a motor body and a cooling water jacket according to any one of the above embodiments, which is sleeved on the outside of the motor body.

[0084] The structure and principle of the cooling water jacket have been clearly explained in the above embodiments and will not be elaborated here one by one.

[0085] An embodiment of the present application further discloses a vehicle, comprising a vehicle body and the motor according to the above embodiment mounted on the vehicle body.
