Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a controller housing, a controller, and a vehicle. Background Technology

[0002] With the continuous advancement of vehicle technology, new energy vehicles are becoming increasingly popular. As the core driving component of new energy vehicles, the electric drive system faces increasingly stringent performance requirements. Consequently, the controller, as a key control unit of the electric drive system, also faces higher demands in terms of integration, operating efficiency, and reliability.

[0003] To effectively regulate the controller's operating temperature, the inner side of the controller housing is typically designed with cooling channels, and a pump drives the coolant for heat exchange. Currently, in some vehicles, the controller is installed at an angle, with the coolant flowing from bottom to top. Because there are multiple heat-generating components inside the controller, the coolant flow path often needs to be extended to achieve effective heat dissipation in different areas. This design increases pumping resistance, leading to increased pump power consumption and consequently, increased overall energy consumption. Utility Model Content

[0004] This application provides a controller housing, a controller, and a vehicle to solve related technical problems.

[0005] This application provides a controller housing for installation on an electric drive device, comprising: a housing body and a partition; the housing body has a first mounting position and a second mounting position on both sides in a first direction; in a second direction perpendicular to the first direction, the housing body includes a first end and a second end disposed opposite to each other; when the controller housing is installed on the electric drive device, in the height direction, the first end is higher than the second end; a flow channel space is provided on the inner side of the housing body; the partition connects the first end and the second end and divides the flow channel space into a first flow channel and a second flow channel; the first flow channel is aligned with the first mounting position; the second flow channel is aligned with the second mounting position; the partition has a connecting port near the first end, the connecting port connecting the first flow channel and the second flow channel; the second end has an inlet connected to the first flow channel and an outlet connected to the second flow channel.

[0006] By designing a connecting port and positioning it near the higher first end, the coolant enters the second flow channel through the connecting port and reaches the outlet under the assistance of gravity. This reduces the active pumping distance of the coolant, thereby decreasing overall energy consumption.

[0007] Furthermore, the first flow channel is provided with a first guide rib near the first end and a second guide rib near the second end. The first guide rib extends along the second direction, and the extension direction of the second guide rib intersects the second direction. The coolant pressure is lower near the first end and higher near the second end. By providing the first guide rib, the coolant with lower pressure can be guided, ensuring that the coolant can flow normally. By providing the second guide rib, the coolant flow rate can be reduced, thereby improving the heat dissipation effect.

[0008] Furthermore, the second mounting position includes a first sub-mounting position and a second sub-mounting position, and the second flow channel includes a first sub-flow channel aligned with the first sub-mounting position and a second sub-flow channel aligned with the second sub-mounting position. By providing multiple sub-mounting positions and sub-flow channels, the controller housing can mount multiple electrical modules and provide heat dissipation, thereby improving the integration of the controller.

[0009] Furthermore, the first mounting position includes a third sub-mounting position and a fourth sub-mounting position, and the first flow channel includes a third sub-flow channel aligned with the third sub-mounting position and a fourth sub-flow channel aligned with the fourth sub-mounting position. The third sub-flow channel connects the first sub-flow channel and the second sub-flow channel. By providing the third and fourth sub-mounting positions, the number of electrical modules that can be installed in the controller housing is further increased, thereby improving the integration of the controller. At the same time, by using the third sub-flow channel to connect the first and second sub-flow channels, additional flow channels are not required when adding electrical modules, further improving the integration of the controller.

[0010] Furthermore, the first sub-mounting position and the second sub-mounting position are spaced apart along the second direction; the third sub-mounting position is located between the first sub-mounting position and the second sub-mounting position. By placing the third sub-mounting position between the first sub-mounting position and the second sub-mounting position, the compactness of the mounting position distribution is improved, and the integration of the controller is enhanced.

[0011] Furthermore, the fourth sub-mounting position is provided with a clearance space, and the third sub-mounting position is located within the clearance space. This arrangement further improves the compactness of the mounting position distribution, thereby further enhancing the integration of the controller.

[0012] Furthermore, the first flow channel includes a first expansion section disposed near the second end, and the inner diameter of the first flow channel gradually increases in the direction from the second end to the first end. By providing the first expansion section, the coolant flow rate can be reduced, thereby improving the cooling effect.

[0013] Furthermore, the first flow channel also includes a narrowing section; the narrowing section extends from the end of the first expansion section toward the first end; the average inner diameter of the narrowing section is smaller than the average inner diameter of the first expansion section. By setting the narrowing section, the water pressure can be increased, ensuring normal cooling flow.

[0014] Furthermore, the first flow channel also includes a second expansion section, which extends from the end of the narrowing section toward the first end; the average inner diameter of the second expansion section is larger than the average inner diameter of the narrowing section. By providing a second expansion section at the end of the narrowing section, the water pressure can be reduced to a certain extent, reducing the impact between the coolant and the first flow channel, allowing the coolant to normally enter the second flow channel through the connecting port, thus ensuring cooling efficiency.

[0015] A second aspect of this application provides a controller, comprising: a first electrical module, a second electrical module, and the aforementioned controller housing, wherein the first electrical module is mounted to a first mounting position, and the second electrical module is mounted to a second mounting position. The controller of this application can reduce the energy consumption of the pump body, thereby reducing the overall power consumption of the vehicle.

[0016] A third aspect of this application provides a vehicle including a pump body and the aforementioned controller; the pump body is connected to the water inlet. The vehicle of this application has low power consumption.

[0024] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0026] Currently, in some vehicles, the controller is installed at an angle, with the coolant flowing from bottom to top. Because the controller contains multiple heat-generating components, the coolant flow path often needs to be extended to effectively dissipate heat from different areas. This design increases pumping resistance, leading to higher pump power consumption and consequently higher overall energy consumption. This application provides a controller housing, a controller, and a vehicle to address these technical problems.

[0027] like Figure 1 and Figure 2 As shown, a first aspect of this application provides a controller housing for mounting to an electric drive device. The controller housing includes a housing body 10 and a partition 20. The housing body 10 has a first mounting position 11 and a second mounting position 12 on both sides in a first direction X. The first direction X may be the length direction of the housing body 10. The second direction Y may be the thickness direction of the housing body 10. The first mounting position 11 and the second mounting position 12 may be mounting openings.

[0028] In a second direction Y perpendicular to the first direction X, the housing body 10 includes a first end 13 and a second end 14 disposed opposite to each other. When the controller housing is installed on the electric drive device, the first end 13 is higher than the second end 14 in the height direction.

[0029] A flow channel space 100 is provided on the inner side of the shell body 10. A separator 20 connects the first end 13 and the second end 14 and divides the flow channel space 100 into a first flow channel 101 and a second flow channel 102. The first flow channel 101 is aligned with the first mounting position 11. The second flow channel 102 is aligned with the second mounting position 12.

[0030] The separator 20 has a connecting port 21 near the first end 13. The connecting port 21 connects the first flow channel 101 and the second flow channel 102. The second end 14 has an inlet 15 and an outlet 16. The first end 13 may have an inlet connector 151 and an outlet connector 161. The inlet 15 has an inlet connector 151. The outlet 16 is located at the outlet connector 161. The inlet 15 connects to the first flow channel 101. The outlet 16 connects to the second flow channel 102.

[0031] By setting the connecting port 21 and positioning it close to the higher first end 13, the coolant can enter the second flow channel 102 through the connecting port 21 and reach the outlet 16 under the assistance of gravity. Therefore, the active pumping distance of the coolant is reduced, thereby reducing the overall energy consumption.

[0032] The housing body 10 is provided with multiple mounting lugs 17 and multiple mounting protrusions 18. The mounting lugs 17 are used to fix the housing body 10 to the electric drive assembly. The mounting protrusions 18 are used to fix electrical components such as power modules.

[0033] Please refer to the following: Figure 3 As shown, the first flow channel 101 includes a first expansion section 103, a narrowing section 104, and a second expansion section 105. The first expansion section 103 may be trapezoidal and is located near the second end 14. The inner diameter of the first flow channel 101 gradually increases from the second end 14 to the first end 13. Since the area near the second end 14 has a relatively high water pressure, by providing the first expansion section 103, the coolant flow rate can be reduced while ensuring normal coolant flow, allowing for sufficient heat exchange and improving the cooling effect.

[0034] The narrowing section 104 can be straight, extending from the end of the first expansion section 103 toward the first end 13. The average inner diameter of the narrowing section 104 is smaller than the average inner diameter of the first expansion section 103. By providing the narrowing section 104, the water pressure can be increased, ensuring normal flow of coolant.

[0035] The second expansion section 105 may be rectangular, extending from the end of the narrowing section 104 toward the first end 13. The average inner diameter of the second expansion section 105 is larger than the average inner diameter of the narrowing section 104. By providing the second expansion section 105 at the end of the narrowing section 104, the water pressure can be reduced to a certain extent, reducing the impact between the coolant and the first flow channel 101, allowing the coolant to normally enter the second flow channel 102 through the connecting port 21, thus ensuring cooling efficiency.

[0036] The second mounting position 12 includes a first sub-mounting position 121 and a second sub-mounting position 122. The second flow channel 102 includes a first sub-flow channel 1021 and a second sub-flow channel 1022. The first sub-mounting position 121 is aligned with the first sub-flow channel 1021. The second sub-mounting position 122 is aligned with the second sub-flow channel 1022. By setting multiple sub-mounting positions and aligned sub-flow channels, the controller housing can install multiple electrical modules and provide heat dissipation, improving the integration of the controller. The first sub-mounting position 121 and the second sub-mounting position 122 can be used for the installation of power modules.

[0037] The first mounting position 11 includes a third sub-mounting position 111 and a fourth sub-mounting position 112. The third sub-mounting position 111 can be used to mount a relay module. The fourth sub-mounting position 112 can be used to mount a bus capacitor. The first flow channel 101 may include the third sub-flow channel 1011 and the fourth sub-flow channel 1012. In an embodiment where the first flow channel 101 includes a first expansion section 103, a narrowing section 104, and a second expansion section 105, the fourth sub-flow channel 1012 may include the first expansion section 103, the narrowing section 104, and the second expansion section 105.

[0038] The third sub-mounting position 111 is aligned with the third sub-flow channel 1011. The fourth sub-mounting position 112 is aligned with the fourth sub-flow channel 1012. The third sub-flow channel 1011 connects the first sub-flow channel 1021 and the second sub-flow channel 1022.

[0039] By setting the third sub-mounting position 111 and the fourth sub-mounting position 112, the number of electrical modules that can be installed in the controller housing is increased, further improving the integration of the controller. At the same time, by using the third sub-flow channel 1011 to connect the first sub-flow channel 1021 and the second sub-flow channel 1022, the addition of electrical modules does not require the separate setting of additional flow channels, further improving the integration of the controller.

[0040] The first sub-mounting position 121 and the second sub-mounting position 122 are spaced apart along the second direction Y. The third sub-mounting position 111 is located between the first sub-mounting position 121 and the second sub-mounting position 122. By placing the third sub-mounting position 111 between the first sub-mounting position 121 and the second sub-mounting position 122, the compactness of the mounting position distribution is improved, thereby increasing the integration of the controller.

[0041] The fourth sub-mounting position 112 is provided with a clearance space 113, and the third sub-mounting position 111 is located within the clearance space 113. The fourth sub-mounting position 112 can be U-shaped. The third sub-mounting position 111 can be square. This arrangement further improves the compactness of the distribution of multiple mounting positions, thereby further improving the integration of the controller.

[0042] A first guide rib 22 and a second guide rib 23 are provided within the first flow channel 101. The first guide rib 22 and the second guide rib 23 are formed by protrusions from the separator 20. The first guide rib 22 is located near the first end 13. The second guide rib 23 is located near the second end 14. The first guide rib 22 extends along the second direction Y, and the extension direction of the second guide rib 23 intersects the second direction Y.

[0043] The coolant pressure is lower near the first end 13 and higher near the second end 14. The first guide rib 22 guides the coolant at lower pressure, ensuring its proper flow. The second guide rib 23 reduces the coolant flow rate, improving heat dissipation.

[0044] The following is a detailed description of the coolant's movement within the controller housing:

[0045] like Figure 3 As shown, firstly, the coolant enters the fourth sub-channel 1012 through the inlet 15. Then, the coolant enters the first expansion section 103 and collides with the second guide rib 23. The flow velocity in the first expansion section 103 is low, ensuring sufficient heat exchange for the electrical modules installed in the fourth sub-mounting position 112. Afterward, the coolant passes through the narrowing section 104 and enters the second expansion section 105. Due to its higher position, the coolant pressure in the second expansion section 105 is lower. The first guide rib 22 guides the coolant flow, ensuring it reaches the connecting port 21 normally.

[0046] Please refer to the following: Figure 4 As shown, coolant enters the first sub-channel 1021 through the connecting port 21 to dissipate heat from the electrical module installed in the first sub-mounting position 121. Under the influence of gravity, the coolant enters the third sub-channel 1011 to dissipate heat from the electrical module installed in the third sub-mounting position 111. Under the continued influence of gravity, the coolant flows from the third sub-channel 1011 into the second sub-channel 1022 to dissipate heat from the electrical module installed in the second sub-mounting position 122, and finally exits through the outlet 16.

[0047] A second aspect of this application provides a controller including a first electrical module (not shown), a second electrical module (not shown), and the aforementioned controller housing. The first electrical module is mounted to a first mounting position, and the second electrical module is mounted to a second mounting position. The controller of this application can reduce the energy consumption of the pump body, thereby reducing the overall power consumption of the vehicle.

[0048] A third aspect of this application provides a vehicle including a pump body (not shown) and the aforementioned controller. The pump body is connected to the water inlet 15. The vehicle of this application has low power consumption. The vehicle of this application can be an electric vehicle or a hybrid vehicle, and the specific type is not limited.

[0049] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
