Description

Technical Field

[0001] This application relates to the field of drive technology, and more specifically, to a cooling housing and a motor. Background Technology

[0002] In related technologies, cooling channels are formed inside the motor housing. By circulating coolant within these channels, the motor can be cooled. Typically, the cooling channels have inlets and multiple outlets along their length, allowing for the selection of which outlets to be connected or blocked depending on the actual usage of the motor.

[0003] In actual use, connecting different outlets on the cooling channel can easily cause coolant to stagnate in some parts of the cooling channel, which in turn can cause excessive local temperature rise in the motor. Summary of the Invention

[0004] The main objective of this application is to provide a cooling housing and motor to solve the problem in the related art where coolant tends to stagnate in the motor cooling channel, resulting in excessive local temperature rise of the motor.

[0005] According to one aspect of this application, a cooling housing is provided, comprising: The housing has a main flow channel, a first branch flow channel and a second branch flow channel inside. The main flow channel has a liquid inlet section. The first branch flow channel is connected to the main flow channel. Multiple liquid outlet sections are arranged at intervals along the length of the first branch flow channel. The liquid outlet sections can be selectively opened. The first end of the second branch flow channel is connected to the end of the main flow channel near the liquid outlet section. The second end of the second branch flow channel is connected to the liquid outlet section farthest from the main flow channel. A first barrier component is disposed in the housing to at least connect or disconnect the main flow channel from the liquid outlet section closest to the main flow channel.

[0006] In some embodiments, the first blocking member is disposed in the outlet section closest to the main flow channel, and the first blocking member has a first position that connects the main flow channel with the outlet section and a second position that disconnects the main flow channel from the outlet section.

[0007] In some embodiments, a first limiting groove is provided in the liquid outlet section, and the first blocking component includes a first partition plate, which is detachably disposed in the first limiting groove to switch between the first position and the second position.

[0008] In some embodiments, the first limiting groove is formed on the inner wall of the liquid outlet section and located on the side close to the main flow channel, and the first baffle has: The first limiting segment is embedded in the first limiting groove; The first blocking section is connected to the first limiting section. The first blocking section extends along the axial direction of the liquid outlet section and closes the main flow channel, thus being in the second position.

[0009] In some embodiments, the maximum depth A of the first limiting groove along the radial direction of the liquid outlet section satisfies the relationship: 1.5mm≤A≤2.5mm.

[0010] In some embodiments, a second limiting groove communicating with the first limiting groove is provided in the liquid outlet section, and the cooling housing further includes a first limiting member, which is detachably disposed in the second limiting groove to limit the first partition plate in the first limiting groove.

[0011] In some embodiments, the cooling housing further includes a plurality of sealing elements, which are detachable and selectively disposed in the liquid outlet section.

[0012] In some embodiments, the liquid inlet section includes multiple liquid inlet sections, which can be selectively opened. A third branch flow channel is also provided in the housing. Along the length direction of the main flow channel, the liquid inlet sections are spaced apart. The first end of the third branch flow channel is connected to the main flow channel and is located at the liquid inlet section closest to the liquid outlet section. The second end of the third branch flow channel is connected to the liquid inlet section farthest from the liquid outlet section. The cooling housing also includes a second barrier component disposed on the housing to at least connect or disconnect the main flow channel between the inlet section and the outlet section from the inlet section closest to the outlet section.

[0013] In some embodiments, the second blocking member is disposed in the inlet section closest to the outlet section, and the second blocking member has a third position that connects the main flow channel between the inlet section and the outlet section to the inlet section and a fourth position that disconnects the main flow channel between the inlet section and the outlet section from the inlet section.

[0014] In other embodiments, this application also includes an electric motor that includes the aforementioned cooling housing.

[0015] In this application, because the cooling housing is provided with a first branch flow channel and a second branch flow channel, when one outlet section is opened while the others are blocked, the main flow channel can be connected to or disconnected from the outlet section closest to the main flow channel. This allows the cooling material to pass through the main flow channel, the first branch flow channel, and the second branch flow channel, preventing the stagnation of cooling material in the main flow channel, the first branch flow channel, or the second branch flow channel, or preventing the flow rate of the cooling material from being too low, which could lead to excessive local temperature rise of the motor. For example, when the outlet section closest to the main flow channel is opened, while the outlets of the other outlet sections are blocked, the main flow channel is disconnected from the outlet section closest to the main flow channel by the first blocking component. The cooling material in the main flow channel will flow through the second branch flow channel into the outlet section farthest from the main flow channel, then flow through the first branch flow channel through the other outlet sections, and finally flow into the outlet section closest to the main flow channel, from which it will flow out, thus completing the circulation of the cooling material. When the outlet of the liquid outlet section closest to the main flow channel is closed and another liquid outlet section is opened, the first blocking component connects the main flow channel with the liquid outlet section closest to the main flow channel. Part of the cooling material in the main flow channel flows through the second branch flow channel to the liquid outlet section furthest from the main flow channel, and finally flows through the first branch flow channel to the opened liquid outlet section. The other part of the cooling material in the main flow channel enters the liquid outlet section closest to the main flow channel, and finally flows through the first branch flow channel to the opened liquid outlet section. It can be understood that the cooling housing of this application can connect or disconnect the main flow channel from the liquid outlet section closest to the main flow channel through the first blocking component, so that after the outlet of a specific liquid outlet section is opened, the cooling material can flow through the main flow channel, the first branch flow channel, and the second branch flow channel, preventing the retention of cooling material in the main flow channel, the first branch flow channel, or the second branch flow channel, and avoiding excessive local temperature rise of the motor.

[0021] To address the issues in the relevant technologies, see [link / reference]. Figures 1 to 5As shown in the figure, this application embodiment provides a motor, which includes a cooling housing, the cooling housing including a shell 10 and a first blocking component 21. The shell 10 has a main flow channel 11, a first branch flow channel 12, and a second branch flow channel 13. The main flow channel 11 has a liquid inlet section 111. The first branch flow channel 12 communicates with the main flow channel 11. Multiple liquid outlet sections 112 are spaced apart along the length of the first branch flow channel 12, and the liquid outlet sections 112 can be selectively opened. The first end of the second branch flow channel 13 is connected to the end of the main flow channel 11 near the liquid outlet section 112, and the second end of the second branch flow channel 13 is connected to the liquid outlet section 112 furthest from the main flow channel 11. The first blocking component 21 is disposed on the shell 10 to at least connect or disconnect the main flow channel 11 from the liquid outlet section 112 closest to the main flow channel 11.

[0022] In this application, since the cooling housing is provided with a first branch flow channel 12 and a second branch flow channel 13, when one outlet section 112 is opened while the other outlet sections 112 are blocked, the main flow channel 11 can be connected to or disconnected from the outlet section 112 closest to the main flow channel 11. This allows the cooling material to pass through the main flow channel 11, the first branch flow channel 12, and the second branch flow channel 13, preventing the cooling material from stagnating in the main flow channel 11, the first branch flow channel 12, or the second branch flow channel 13, or preventing the flow rate of the cooling material from being too low, which would lead to excessive local temperature rise of the motor. For example, when the outlet section 112 closest to the main flow channel 11 is opened while the outlets of the other outlet sections 112 are blocked, the main flow channel 11 and the outlet section 112 closest to the main flow channel 11 are disconnected by the first blocking component 21. The cooling material in the main flow channel 11 flows through the second branch flow channel 13 into the liquid outlet section 112, which is furthest from the main flow channel 11. Then it flows through the first branch flow channel 12 through the remaining liquid outlet sections 112, and finally flows into the liquid outlet section 112 closest to the main flow channel 11, from which it flows out, thus completing the circulation of the cooling material. When the outlet of the liquid outlet section 112 closest to the main flow channel 11 is closed and the other liquid outlet section 112 is opened, the first blocking component 21 connects the main flow channel 11 with the liquid outlet section 112 closest to the main flow channel 11. Part of the cooling material in the main flow channel 11 flows through the second branch flow channel 13 to the liquid outlet section 112 furthest from the main flow channel 11, and finally flows through the first branch flow channel 12 to the opened liquid outlet section 112. The other part of the cooling material in the main flow channel 11 enters the liquid outlet section 112 closest to the main flow channel 11, and finally the cooling material flows through the first branch flow channel 12 into the opened liquid outlet section 112. It is understood that the cooling housing of this application can connect or disconnect the main flow channel 11 and the liquid outlet section 112 closest to the main flow channel 11 through the first blocking component 21, so that after the outlet of a specific liquid outlet section 112 is opened, the cooling material can flow through the main flow channel 11, the first branch flow channel 12 and the second branch flow channel 13, preventing the cooling material from being retained in the main flow channel 11, the first branch flow channel 12 or the second branch flow channel 13, and avoiding excessive local temperature rise of the motor.

[0023] In some embodiments, the first blocking member 21 is disposed in the liquid outlet section 112 closest to the main flow channel 11, and the first blocking member 21 has a first position that connects the main flow channel 11 with the liquid outlet section 112 and a second position that disconnects the main flow channel 11 from the liquid outlet section 112.

[0024] Specifically, the liquid outlet section 112 is provided with a liquid outlet hole 1121, which is connected to the main flow channel 11 and the first branch flow channel 12. When the opening of the liquid outlet section 112, which is closest to the main flow channel 11, needs to be opened, the first blocking component 21 switches to the second position, so that the main flow channel 11 is disconnected from the liquid outlet section 112. In this embodiment, the second position of the first blocking component 21 can be inside or outside the liquid outlet hole 1121. When one of the other liquid outlet sections 112 is opened, the first blocking component 21 switches to the first position, so that the main flow channel 11 is connected to the liquid outlet section 112. In this embodiment, the first position of the first blocking component 21 is located at the connection between the liquid outlet hole 1121 and the first branch flow channel 12.

[0025] In some embodiments, a first limiting groove 1112 is provided in the liquid outlet section 112, and the first blocking component 21 includes a first partition plate. The first partition plate is detachably disposed in the first limiting groove 1112 to switch between a first position and a second position. In this embodiment, when the liquid outlet section 112 closest to the main flow channel 11 is closed, the first partition plate is removed from the liquid outlet section 112, and the main flow channel 11 communicates with the liquid outlet section 112. When the outlet section 112 closest to the main flow channel 11 is opened, the cooling material needs to flow in the main flow channel 11, the first branch flow channel 12, and the second branch flow channel 13. Therefore, the main flow channel 11 needs to be disconnected from the outlet section 112 closest to the main flow channel 11 to prevent the cooling material in the main flow channel 11 from flowing out of the outlet section 112. This would cause the flow rate of the cooling material in the main flow channel 11 into the second branch flow channel 13 to be too low or not to enter the second branch flow channel 13, resulting in the problem of the cooling material in the second branch flow channel 13 or the first branch flow channel 12 being stuck and not flowing.

[0026] In other embodiments, the cooling housing also includes a controller, and the first blocking component 21 includes a solenoid valve electrically connected to the controller. When the opening of the outlet section 112 closest to the main flow channel 11 is open, the controller controls the solenoid valve to switch to a second position to disconnect the main flow channel 11 from the outlet section 112; and when the opening of the outlet section 112 closest to the main flow channel 11 is closed, the controller controls the solenoid valve to switch to a first position to connect the main flow channel 11 with the outlet section 112. Compared to the design where the first blocking component 21 is a first partition, the scheme using a solenoid valve in conjunction with the controller is more convenient to operate, eliminating the need for manual disassembly and assembly of the first partition.

[0027] In some embodiments, a first limiting groove 1112 is formed on the inner wall of the liquid outlet section 112 and located on the side close to the main flow channel 11. The first baffle has a first limiting section 211 and a first blocking section 212. The first limiting section 211 is embedded in the first limiting groove 1112, and the first blocking section 212 is connected to the first limiting section 211. The first blocking section 212 extends along the axial direction of the liquid outlet section 112 and closes the main flow channel 11, thus being in a second position.

[0028] In one specific embodiment, the first limiting groove 1112 is a semi-circular limiting groove, and the first limiting segment 211 is a semi-circular bent segment. When the first partition plate needs to be assembled, the end of the first blocking segment 212 facing away from the first limiting segment 211 is abutted against the bottom wall of the liquid outlet segment 112, and then the first limiting segment 211 is embedded in the first limiting groove 1112. At this time, the first blocking segment 212 blocks the connection between the main flow channel 11 and the liquid outlet segment 112. In this embodiment, the cooperation of the first limiting groove 1112 and the first limiting segment 211 is used to apply a radial limiting effect to the first blocking segment 212 along the liquid outlet hole 1121, preventing the first blocking segment 212 from being impacted open by the pressure exerted by the cooling material in the main flow channel 11, thus preventing the main flow channel 11 from accidentally connecting with the liquid outlet hole 1121.

[0029] In some embodiments, the maximum depth A of the first limiting groove 1112 along the radial direction of the liquid outlet section 112 satisfies the relationship: 1.5mm ≤ A ≤ 2.5mm. Specifically, if A is less than 1.5mm, the embedding depth of the first limiting segment 211 into the first limiting groove 1112 is insufficient. When the cooling material in the main flow channel 11 exerts a large impact force on the first blocking segment 212, the first limiting segment 211 will detach from the first limiting groove 1112, ultimately causing the first blocking segment 212 to fail to seal the connection between the main flow channel 11 and the liquid outlet 1121. If A is greater than 2.5mm, this will reduce the structural strength of the liquid outlet section 112, and the resistance experienced by the first limiting segment 211 will be greater when embedding the first limiting segment 211 into the first limiting groove 1112 or removing the first limiting segment 211 from the first limiting groove 1112. When A satisfies the above relationship, it ensures that the first barrier section 212 has sufficient impact resistance, and avoids problems such as excessively low structural strength of the liquid outlet section 112 or difficulty in assembling the first limiting section 211. In this embodiment, the value of A can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm.

[0030] In some embodiments, a second limiting groove 1113 communicating with the first limiting groove 1112 is provided in the liquid outlet section 112, and the cooling housing also includes a first limiting member 41, which is detachably disposed in the second limiting groove 1113 to limit the first partition plate in the first limiting groove 1112.

[0031] In this embodiment, the first limiting member 41 includes a retaining ring. After the first partition is assembled into the first limiting groove 1112, the retaining ring is then installed. The retaining ring applies pressure to the first limiting segment 211, thereby limiting the first limiting segment 211 within the first limiting groove 1112. Specifically, the pressure applied by the first limiting member 41 to the first limiting segment 211 increases the friction between the first limiting segment 211 and the inner wall surfaces of the first limiting member 41 and the first limiting groove 1112, preventing the first limiting segment 211 from disengaging from the first limiting groove 1112 under external force. Simultaneously, the downward pressure applied by the first limiting member 41 to the first limiting segment 211 can be transmitted to the first blocking segment 212 to prevent the first blocking segment 212 from moving along the axial direction of the liquid outlet 1121 under external force.

[0032] In some embodiments, a groove 1114 is formed on the inner bottom wall of the liquid outlet 1121, and one end of the first blocking section 212 facing away from the first limiting section 211 is located in the groove 1114. That is, when the first blocking section 212 is in the second position, the end of the first blocking section 212 facing away from the first limiting section 211 abuts against the bottom surface of the groove 1114, thereby preventing the cooling material from flowing out through the gap between the first blocking section 212 and the inner bottom wall of the liquid outlet 1121.

[0033] In some embodiments, a sealing layer is provided on the side of the first barrier section 212 near the main flow channel 11. When the first barrier section 212 is in the second position, the sealing layer is in contact with the inner wall surface of the liquid outlet hole 1121, thereby sealing the connection between the main flow channel 11 and the liquid outlet hole 1121 and preventing the cooling medium in the main flow channel 11 from leaking through the gap between the first barrier section 212 and the inner wall surface of the liquid outlet hole 1121.

[0034] In some embodiments, the cooling housing further includes a plurality of sealing members 30, which are detachably and selectively disposed on the liquid outlet sections 112. Specifically, typically only one liquid outlet section 112 is opened, while the remaining liquid outlet sections 112 are sealed with the sealing members 30. Of course, the number of liquid outlet sections 112 that are opened can also be flexibly selected according to the actual needs of the motor, such as the spatial layout of the motor.

[0035] In practice, multiple liquid inlet sections 111 need to be provided on the housing 10. Since the motor is placed in different positions in different devices, if only one liquid inlet section 111 is provided, it may be blocked in some devices, making it difficult to connect to the liquid supply line that provides the cooling material. Therefore, multiple liquid inlet sections 111 are required so that the liquid supply line can be connected to one of the liquid inlet sections 111 according to actual needs. Therefore, in some embodiments, multiple liquid inlet sections 111 are provided, and multiple liquid inlet sections 111 can be selectively opened. A third branch flow channel 14 is also provided in the housing 10. Along the length direction of the main flow channel 11, the liquid inlet sections 111 are arranged at intervals. The first end of the third branch flow channel 14 is connected to the main flow channel 11 and is located at the liquid inlet section 111 closest to the liquid outlet section 112. The second end of the third branch flow channel 14 is connected to the liquid inlet section 111 farthest from the liquid outlet section 112. The cooling housing also includes a second barrier component 22, which is disposed in the housing 10 to at least connect or disconnect the main flow channel 11 between the inlet section 111 and the outlet section 112 from the inlet section 111 closest to the outlet section 112.

[0036] Specifically, similar to the design of multiple outlet sections 112, when the inlet section 111 closest to the outlet section 112 is open while the other inlet sections 111 are closed, the cooling material needs to flow through the main flow channel 11 and the third branch flow channel 14. Therefore, the second blocking component 22 disconnects the main flow channel 11 between the inlet section 111 and the outlet section 112 from the inlet section 111. At this time, the cooling material flows from the inlet section 111 into the third branch flow channel 14, and then from the third branch flow channel 14 into the main flow channel 11. When the inlet section 111 closest to the outlet section 112 is closed, and one of the other inlet sections 111 is open, the cooling material flows in two parts within the main flow channel 11 between the outlet section 112 and the nearest inlet section 111. One part flows into the main flow channel 11 through the inlet section 111 closest to the outlet section 112, and the other part flows into the main flow channel 11 through the third branch flow channel 14. The configuration of this embodiment ensures that regardless of which liquid inlet section 111 is open and the other liquid inlet sections 111 are closed, the cooling material can flow through the main flow channel 11 and the third branch flow channel 14, preventing the cooling material from being retained in the third branch flow channel 14.

[0037] In some embodiments, the second blocking member 22 is disposed in the inlet section 111 closest to the outlet section 112. The second blocking member 22 has a third position that connects the main flow channel 11 between the inlet section 111 and the outlet section 112 with the inlet section 111 and a fourth position that disconnects the main flow channel 11 between the inlet section 111 and the outlet section 112 from the inlet section 111.

[0038] Specifically, the inlet section 111 has an inlet hole 1111, and the sealing member 30 is detachably used to seal the inlet hole 1111. The second blocking member 22 can be a second baffle or a solenoid valve. When the inlet section 111 closest to the outlet section 112 is open, the second blocking member 22 is in the fourth position; and when the inlet section 111 closest to the outlet section 112 is closed, and one of the other inlet sections 111 is open, the second blocking member 22 is in the third position.

[0039] In some embodiments, a third limiting groove 1122 is formed in the liquid inlet section 111, and the second blocking member 22 includes a second partition plate. The second partition plate is detachably disposed in the third limiting groove 1122 to switch between a third position and a fourth position. Furthermore, the third limiting groove 1122 is formed on the inner wall of the liquid inlet section 111. The second partition plate includes a second limiting section and a second blocking section. The second limiting section is embedded in the third limiting groove 1122, and the second blocking section is connected to the second limiting section. It extends along the axial direction of the liquid inlet section 111 and closes the main flow channel 11, thus being in the fourth position. A fourth limiting groove 1123 communicating with the third limiting groove 1122 is formed in the liquid inlet section 111. The cooling housing also includes a second limiting member 42, which is detachably disposed in the fourth limiting groove 1123 to limit the second partition plate within the third limiting groove 1122. Similarly, the second partition is also provided with a second limiting section 221 and a second blocking section 222.

[0040] Similar to the arrangement of the liquid outlet section 112, the third limiting groove 1122, the fourth limiting groove 1123 and the second limiting member 42 are used to fix the second partition in the liquid inlet section 111, and prevent the second partition from being opened by the main flow channel 11 or from moving in the axial direction of the liquid inlet hole 1111 due to external force.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0043] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
