DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise specified, the directional words used, such as "inside" and "outside", generally refer to the "inside" and "outside" relative to the corresponding component's own outline, and the terms "first" and "second" are used to distinguish one element from another element, and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0028] According to the specific implementation of the present disclosure, Figures 1 to 5 As shown in , a cooling water jacket 100 is provided, which includes a main body 110 and a cooling channel 120 formed on the main body 110, and the cooling channel 120 includes an inlet channel 121 and an outlet channel 122, which are arranged at intervals and connected.

[0029] Typically, as the cooling medium enters the cooling channel 120 from the beginning of the water inlet channel 121 and flows toward the end of the water outlet channel 122 , as the cooling medium further exchanges heat, the temperature of the cooling medium at the water inlet channel 121 is typically lower than the temperature of the cooling medium at the water outlet channel 122 .

[0030] However, through the above technical solution, in the cooling water jacket provided in the present invention, a cooling channel 120 including a water inlet channel 121 and a water outlet channel 122 is formed on the main body 110, wherein the water inlet channel 121 and the water outlet channel 122 are arranged at intervals and interconnected, thereby enabling the cooling medium in the water outlet channel 122 to exchange heat with the cooling medium in the water inlet channel 121, so as to avoid uneven heat dissipation caused by uneven temperature of the cooling medium, thereby improving the uniformity of heat dissipation of the motor by the cooling water jacket 100.

[0031] In the cooling water jacket provided in the present disclosure, the water inlet channel 121 and the water outlet channel 122 can be constructed in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 1 or Figure 2 As shown in the figure, the water inlet channel 121 and the water outlet channel 122 can both extend in a circumferential spiral along the main body 110, that is, the water inlet channel 121 and the water outlet channel 122 can be set as double spiral channels 210 parallel to each other, and the cooling channel 120 has a first end and a second end relative to each other, and the water inlet channel 121 and the water outlet channel 122 both extend from the first end of the cooling water jacket 100 toward the second end, and are connected at the second end. At this time, the first end of the cooling water jacket 100 is formed with the starting end of the water inlet channel 121 and the end of the water outlet channel 122, and the second end of the cooling water jacket 100 is formed with the end of the water inlet channel 121 and the starting end of the water outlet channel 122, and the end of the water inlet channel 121 is connected with the starting end of the water outlet channel 122 at the second end, so that the requirements that the water inlet channel 121 and the water outlet channel 122 are spaced apart and connected with each other can be met.

[0032] In the cooling water jacket provided in the present disclosure, the water inlet channel 121 and the water outlet channel 122 can be connected in any suitable manner, and the present disclosure does not impose any specific limitation on this. Figure 1 or Figure 2 As shown in the figure, the cooling channel 120 may include a reversing channel 123, which is arranged between the end of the water inlet channel 121 and the beginning of the water outlet channel 122, and connects the water inlet channel 121 and the water outlet channel 122. In this way, when the cooling medium flows through the water inlet channel 121, it enters the reversing channel 123 from the end of the water inlet channel 121, and enters the beginning of the water outlet channel 122 after flowing through the reversing channel 123. That is to say, the reversing channel 123 is used to convert the flow direction of the cooling medium to divide the cooling channel 120 into a continuous water inlet channel 121 and a water outlet channel 122.

[0033] As an exemplary embodiment, reference is made to Figure 1 and Figure 2As shown in, a guide plate 130 can be provided in the reversing flow channel 123, and the guide plate 130 can be constructed as a U-shaped plate, and divides the reversing flow channel 123 into a first branch flow channel and a second branch flow channel, the second branch flow channel is arranged around the first branch flow channel, and the first branch flow channel and the second branch flow channel are both connected to the water inlet flow channel 121 and the water outlet flow channel 122. In this way, when the cooling medium flows along the water inlet flow channel 121 to the reversing flow channel 123 and contacts the guide plate 130, it is divided into two parts by the guide plate 130, enters the first branch flow channel and the second branch flow channel respectively, and merges at the beginning of the water outlet flow channel 122 after flowing through the first branch flow channel and the second branch flow channel. That is to say, the guide plate 130 is used to separate the cooling medium flowing into the reversing flow channel 123, so as to avoid the vortex phenomenon caused by the cooling medium at the reversing flow channel 123 due to the change of flow direction, reduce the flow resistance of the cooling medium at the reversing flow channel 123, and improve the service life of the cooling water jacket 100.

[0034] In the cooling water jacket provided in the present disclosure, the cooling medium can enter the cooling channel 120 in any suitable manner, and the present disclosure does not impose any specific limitation on this. Figure 1 As shown in, the cooling water jacket 100 may include an inlet pipe 140 and an outlet pipe 150 arranged on the main body 110, one end of the inlet channel 121 can be connected to the reversing channel 123, and the other end can be connected to the inlet pipe 140, one end of the outlet channel 122 can be connected to the reversing channel 123, and the other end can be connected to the outlet pipe 150, so that the cooling medium flows from the inlet pipe 140 into the inlet channel 121, flows through the inlet channel 121 and the outlet channel 122, and then enters the outlet pipe 150, and flows out from the outlet pipe 150. When the cooling water jacket 100 provided by the present disclosure is applied to the technical field of motor heat dissipation, the inlet pipe 140 and the outlet pipe 150 can be connected to the cooling water system of the motor to achieve the heat dissipation purpose of the cooling water jacket 100 for the motor.

[0035] In the cooling water jacket provided in the present disclosure, the cooling channel 120 can be formed on the main body 110 of the cooling water jacket 100 in any suitable form, and the present disclosure does not impose any specific limitation on this. Figure 1 and Figure 2As shown in , a plurality of dividing ribs 160 may be provided on the main body 110, and the plurality of dividing ribs 160 are formed on the outer surface of the main body 110 at intervals from each other and extend in a spiral direction along the circumference of the main body 110 to form a cooling channel 120 on the surface of the main body 110. That is, the plurality of dividing ribs 160 protrude from the surface of the main body 110 of the cooling water jacket 100, and divide the surface of the main body 110 into cooling channels 120 for the flow of cooling medium. In this way, when the cooling water jacket 100 provided by the present disclosure is applied to the technical field of motor heat dissipation, the motor housing 200 is sleeved on the outside of the cooling water jacket 100, and the dividing ribs 160 can abut against the inner wall of the motor housing 200, that is, the motor housing 200 can cover the cooling channel 120 formed by the dividing ribs 160 to deform the cooling channel 120 into a channel 210 with a sealed upper portion for the flow of cooling medium.

[0036] In some other embodiments, a cooling channel 120 for the cooling medium to flow can also be formed by digging grooves on the surface of the main body 110 of the cooling water jacket 100. In this embodiment, when the cooling water jacket 100 and the motor housing 200 are installed, the surface of the main body 110 of the cooling water jacket 100 abuts against the motor housing 200, and the cooling channel 120 can also be deformed into a channel 210 with an upper sealed portion for the cooling medium to flow. The present disclosure does not impose specific restrictions on this.

[0037] Based on the above technical solution, the present disclosure also provides a motor, referring to Figure 3 As shown in , the motor includes a motor housing 200 and the above-mentioned cooling water jacket 100, and the motor housing 200 is sleeved on the cooling water jacket 100, so that the cooling water jacket 100 can form a channel 210 for the circulation of the cooling medium together with the motor housing 200, and the cooling medium can contact the motor housing 200 to exchange heat during the flow in the channel 210, thereby achieving heat dissipation of the motor. In addition, the cooling water jacket 100 has all the technical features of the above-mentioned cooling water jacket 100, so they are not described here.

[0038] The channel 210 may be constructed in any suitable manner, and the present disclosure does not impose any specific limitation on this. Figure 3As shown in the figure, the cooling water jacket 100 includes a main body 110 and a plurality of dividing ribs 160, and the plurality of dividing ribs 160 are formed on the outer surface of the main body 110 at intervals, and the dividing ribs 160 can abut against the inner wall of the motor housing 200, so that a channel 210 for the circulation of cooling medium is formed between the main body 110 and the motor housing 200. In this way, a channel 210 for the circulation of cooling medium is formed between the cooling water jacket 100 and the motor housing 200, and the channel 210 is formed by the motor housing 200 covering the cooling channel 120. On the basis of the water inlet channel 121, the reversing channel 123 and the water outlet channel 122, a water inlet channel 210, an annular channel 210 and a water outlet channel 210 are formed, and the cooling medium circulates in the channel 210 to exchange heat with the motor housing 200, thereby realizing heat dissipation of the motor.

[0039] In the motor provided by the present disclosure, the cooling medium can enter the channel 210 in any suitable manner, and the present disclosure does not impose any specific limitation on this. Figure 4 As shown in the figure, the motor housing 200 can be provided with a first through hole 220 and a second through hole 230, and the cooling water jacket 100 includes a water inlet pipe 140 and a water outlet pipe 150, and the water inlet pipe 140 and the water outlet pipe 150 can pass through the first through hole 220 and the second through hole 230 respectively and communicate with the channel 210. In this way, when installing the cooling water jacket 100, the cooling water jacket 100 is firstly inserted into the interior of the motor housing 200, and the cooling water jacket 100 is rotated until the starting end of the water inlet channel 121 and the end of the water outlet channel 122 of the cooling water jacket 100 correspond to the first through hole 220 and the second through hole 230 respectively, and the water inlet pipe 140 and the water outlet pipe 150 pass through the first through hole 220 and the second through hole 230 respectively and communicate with the channel 210.

[0040] In the motor provided by the present disclosure, the cooling water jacket 100 can be connected to the motor housing 200 in any suitable manner, and the present disclosure does not impose any specific restrictions on this. As an exemplary embodiment, the two opposite ends of the cooling water jacket 100 can be respectively welded to the motor housing 200, so that the cooling water jacket 100 can be reliably connected to the motor housing 200, avoiding the cooling water jacket 100 and the motor housing 200 from being poorly sealed and displaced during long-term use; it can also ensure that the separation ribs 160 on the surface of the cooling water jacket 100 are reliably in contact with the motor housing 200, thereby ensuring the sealing of the cooling medium flowing in the channel 210.

[0041] On the basis of the above technical solution, the present disclosure further provides a vehicle, which includes the above motor. The motor includes all the technical features of the above motor, so they are not elaborated here.

[0042] In the vehicle provided by the present disclosure, as an exemplary embodiment, reference is made to Figure 5 As shown in, the vehicle includes a controller, and the controller may include a controller housing 300. The controller housing 300 may be formed with a cooling flow path and provided with a water inlet 310 and a water outlet 320. A channel 210 is formed between the motor and the cooling water jacket 100. The water inlet 310 is used to supply cooling medium to flow into the cooling flow path, and the water outlet 320 is connected with the cooling flow path and the channel 210. The cooling flow path may be connected with the cooling water system of the vehicle. The cooling medium may flow out from the cooling water system through the water inlet 310 and flow into the cooling flow path. After flowing through the cooling flow path, it flows from the water outlet 320 into the channel 210, exchanges heat with the motor housing, and then flows out through the water outlet pipe 150, and finally flows back into the cooling water system. In this way, an integrated cooling structure of the controller and the motor can be formed, and the overall volume of the motor and the controller can be effectively reduced, thereby improving product integration.
