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 development and innovation of new energy vehicle technology, related technologies are also undergoing rapid updates and iterations, significantly improving the overall performance of vehicles. While performance has improved, the power of core components has also increased substantially. However, this increased power has also led to increased heat generation, posing a challenge to the stable operation of the controller.

[0003] The controller contains various electronic devices to operate the vehicle's electrical system. To dissipate heat, cooling channels are typically incorporated into the controller housing. Currently, the integration of the controller housing is poor, resulting in a low level of integration and requiring a significant amount of installation space. Utility Model Content

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

[0005] The first aspect of this application provides a controller housing, including a housing body; the housing body protrudes to both sides to form a first mounting portion and a second mounting portion; the first mounting portion is provided with a first heat dissipation channel, and the second mounting portion is provided with a second heat dissipation channel; the first heat dissipation channel and the second heat dissipation channel are connected; the housing body is provided with a water inlet and a water outlet, the water inlet being connected to the first heat dissipation channel and the water outlet being connected to the second heat dissipation channel.

[0006] By providing a first mounting part and a second mounting part on both sides of the controller housing, electronic devices can be mounted on both sides of the controller housing, which improves the installation and integration effect of the controller housing while ensuring heat dissipation.

[0007] Furthermore, the projections of the first mounting portion and the second mounting portion onto the shell body along the protrusion direction have an overlapping area, and the shell body is provided with a connecting port in the overlapping area, the connecting port connecting the first heat dissipation channel and the second heat dissipation channel.

[0008] Since the connection port is located in the overlapping area of ​​the projections of the first mounting part and the second mounting part, the distance between the first mounting part and the second mounting part is reduced, which makes the arrangement of electronic devices more compact and further improves the installation and integration effect of the controller housing.

[0009] Furthermore, the first mounting part includes a basic mounting part and an extended mounting part, and the first heat dissipation channel includes a basic channel disposed in the basic mounting part and an extended channel disposed in the extended mounting part; the basic channel and the extended channel are separately disposed; the basic channel connects the water inlet and the first heat dissipation channel; the extended channel connects the water outlet and the second heat dissipation channel.

[0010] By combining the first mounting section with the base mounting section and the extension mounting section, the applicability of the controller housing is improved. Users can selectively utilize the base flow channel or the extension flow channel, or both, to dissipate heat from the electronic device, depending on its size.

[0011] Furthermore, the basic mounting portion includes a first segment and a second segment extending from one end of the first segment, the extension directions of the first segment and the second segment intersecting each other.

[0012] Because the extension directions of the first and second segments intersect, the length occupied by the base mounting part in a single direction is reduced, thus improving the structural compactness of the controller housing.

[0013] Furthermore, an angled region is formed between the first segment and the second segment, and the extended mounting portion is disposed within the angled region to further improve the structural compactness of the controller housing.

[0014] Furthermore, the second mounting portion has a mounting opening at one end opposite to the main housing body, and this mounting opening is connected to the second heat dissipation channel. The open design of the second heat dissipation channel allows electronic devices mounted to the mounting opening to directly contact the coolant, thereby improving the heat dissipation effect of the controller housing.

[0015] Furthermore, the second mounting portion is provided with a mounting groove for mounting a seal, the mounting groove surrounding the mounting opening. By providing a mounting groove for mounting the seal, the sealing performance is improved, preventing coolant leakage.

[0016] Furthermore, the first mounting part has an abutment plate on the side opposite to the main body of the housing for heat exchange. The first heat dissipation channel is enclosed and exchanges heat with the electronic device through this abutment. With the first heat dissipation channel enclosed, the electronic device is simply placed against the abutment plate during installation. When installing the electronic device, thermally conductive adhesive needs to be applied between the abutment plate and the electronic device to reduce thermal resistance and improve heat dissipation. Without thermally conductive adhesive, the space between them is considered air-filled, and air has lower thermal conductivity than thermally conductive adhesive. This design places fewer structural restrictions on the electronic device and expands the applicability of the controller housing.

[0017] Furthermore, a guide plate is provided inside the first heat dissipation channel, and the guide plate is arranged along the extension direction of the first heat dissipation channel. By providing the guide plate, the coolant is guided so that it can flow in the direction of the first heat dissipation channel, avoiding the formation of local eddies in the channel and enabling it to smoothly carry away heat, thereby improving the heat exchange effect of the controller housing.

[0018] Furthermore, the side surface of the first mounting portion is recessed towards the first heat dissipation channel to form a clearance space. By providing the clearance space, the assembly of electronic devices can be avoided, further improving the installation and integration effect of the controller housing and enhancing the structural compactness.

[0019] A second aspect of this application provides a controller, including a first device, a second device, and the aforementioned controller housing. The first device is assembled to a first mounting portion, and the second device is assembled to a second mounting portion. By mounting the first device and the second device on opposite sides of the controller housing, the integration level and structural compactness of the controller are improved.

[0020] A third aspect of this application provides a vehicle including the aforementioned controller. Due to the improved compactness of the controller, the vehicle's spatial layout is optimized. The vehicle can provide more space for goods and customers, improving its comfort and convenience.

Detailed Implementation

[0030] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings.

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.

[0032] Currently, the integration of controller housings is poor, resulting in a low level of controller integration and a large overall installation space required. This application provides a controller housing, a controller, and a vehicle to solve these technical problems.

[0033] like Figure 1 and Figure 2As shown, a first aspect of this application provides a controller housing, including a housing body 10. The housing body 10 protrudes to both sides to form a first mounting portion 20 and a second mounting portion 30. The first mounting portion 20 is provided with a first heat dissipation channel 200. The second mounting portion 30 is provided with a second heat dissipation channel 300.

[0034] The first heat dissipation channel 200 is connected to the second heat dissipation channel 300. The shell body 10 is provided with a water inlet 15 and a water outlet 16. The water inlet 15 is connected to the first heat dissipation channel 200. The water outlet 16 is connected to the second heat dissipation channel 300.

[0035] By providing a first mounting portion 20 and a second mounting portion 30 on both sides of the controller housing, electronic devices can be mounted on both sides of the controller housing, improving the installation and integration effect of the controller housing. At the same time, a first heat dissipation channel 200 is provided in the first mounting portion 20 and a second heat dissipation channel 300 is provided in the second mounting portion 300, ensuring the heat dissipation effect of the controller housing.

[0036] like Figure 1 and Figure 2 As shown, the shell body 10 includes a first side 11, a second side 12, a third side 13, and a fourth side 14. The first side 11 and the second side 12 are arranged opposite to each other. Figure 1 and Figure 2 In the indicated viewpoint, the third side 13 connects the top of the first side 11 and the second side 12, and the fourth side 14 connects the bottom of the first side 11 and the second side 12.

[0037] A first mounting portion 20 protrudes from a first side surface 11. A first heat dissipation channel 200 is recessed from the end face of the first mounting portion 20. A second mounting portion 30 protrudes from a second side surface 12. A second heat dissipation channel 300 is recessed from the end face of the second mounting portion 30. A water inlet 15 and a water outlet 16 are located on a third side surface 13. A first connector 41 is press-fitted onto the water inlet 15. A second connector 42 is press-fitted onto the water outlet 16.

[0038] The first mounting portion 20 and the second mounting portion 30 overlap in the projection of their parts onto the shell body 10 along the projection direction. The shell body 10 has a connecting port 17 in the overlapping area 100. The connecting port 17 connects the first heat dissipation channel 200 and the second heat dissipation channel 300.

[0039] Because the projections of the first mounting portion 20 and the second mounting portion 30 overlap, the distance between the first mounting portion 20 and the second mounting portion 30 is shortened. By providing a connection port 17 in the overlapping area 100, the arrangement of electronic devices can be more compact, further improving the installation and integration effect of the controller housing.

[0040] Please refer to the following: Figure 3As shown, the overlapping area 100 includes a first overlapping area 101 and a second overlapping area 102. The connecting port 17 includes a first connecting port 171 and a second connecting port 172. The first connecting port 171 is located in the first overlapping area 101. The second connecting port 172 is located in the second overlapping area 102. The housing body 10 is provided with mounting lugs 18 for mounting and fixing the controller housing itself.

[0041] The first installation section 20 includes a basic installation section 21 and an expansion installation section 22. Please refer to both. Figure 4 As shown, the first heat dissipation channel 200 includes a basic channel 201 and an extended channel 202. The basic channel 201 is disposed within the basic mounting portion 21. The extended channel 202 is disposed within the extended mounting portion 22. The basic channel 201 and the extended channel 202 are separately disposed. The basic channel 201 connects the inlet 15 and the second heat dissipation channel 300. The extended channel 202 connects the outlet 16 and the second heat dissipation channel 300.

[0042] By dividing the first mounting portion 20 into a basic mounting portion 21 and an extended mounting portion 22, the applicability of the controller housing is expanded. Users can selectively utilize the basic flow channel 201 or the extended flow channel 202, or both, to dissipate heat from the electronic device, depending on its size. The first mounting portion 20 is provided with a plurality of first mounting holes 26, allowing the electronic device to be assembled to the first mounting portion 20 by means of screws or other methods.

[0043] Due to its expanded application scope, the controller housing of this application is compatible with a variety of electronic devices. During vehicle charging, the controller can adjust the charging strategy according to the different installed electronic devices, thereby improving the energy conversion efficiency during the charging process.

[0044] In their respective projection directions, the projections of the base mounting portion 21 and the second mounting portion 30 form a first overlapping region 101, and the projections of the extension mounting portion 22 and the second mounting portion 30 form a second overlapping region 102. A first connecting port 171 is provided in the first overlapping region 101 to connect the base flow channel 201 and the second heat dissipation flow channel 300. A second connecting port 172 is provided in the second overlapping region 102 to connect the second heat dissipation flow channel 300 and the extension flow channel 202.

[0045] During heat dissipation, the coolant first enters the base channel 201 through the inlet 15. Then, the coolant in the base channel 201 enters the second heat dissipation channel 300 through the first connecting port 171. Afterward, the coolant in the second heat dissipation channel 300 enters the extension channel 202 through the second connecting port 172. Finally, the coolant in the extension channel 202 returns to the vehicle's thermal management system through the outlet 16.

[0046] The base mounting section 21 includes a first segment 211 and a second segment 212. The second segment 212 extends from one end of the first segment 211. The extension directions of the first segment 211 and the second segment 212 intersect. Because the extension directions of the first segment 211 and the second segment 212 intersect, the length occupied by the base mounting section 21 in a single direction is reduced, further improving the structural compactness of the controller housing.

[0047] exist Figure 3 In the shown viewpoint, the first segment 211 extends downwards, and the second segment 212 extends to the left from the bottom of the first segment 211. The end of the second segment 212 extends upwards to connect to the first connecting port 171.

[0048] An angled region 213 is formed between the first segment 211 and the second segment 212. An extended mounting portion 22 is disposed within the angled region 213 to further improve the structural compactness of the controller housing. Figure 3 In the shown view, the extended mounting part 22 is inverted L-shaped and extends from the position of the second connecting port 172 toward the position of the water outlet 16.

[0049] The side surface 23 of the first mounting part 20 is recessed towards the first heat dissipation channel 200 to form a clearance space 231. By providing the clearance space 231, the assembly of electronic devices can be avoided, further improving the installation and integration effect of the controller housing and increasing the compactness of the controller structure.

[0050] like Figure 1 As shown, the first mounting portion 20 has an abutment plate 24 on the side opposite to the main body 10 for heat exchange. The abutment plate 24 can be fixed to the first mounting portion 20 by friction stir welding. Except for the abutment plate 24, the controller housing can be integrally die-cast to improve structural strength. The first heat dissipation channel 200 is enclosed, and when installing electronic devices, the electronic devices simply abut against the abutment plate 24. This design imposes fewer structural restrictions on the electronic devices and expands the applicability of the controller housing.

[0051] Specifically, when installing electronic devices, thermally conductive adhesive needs to be applied between the contact plate 24 and the electronic device to reduce thermal resistance and improve heat dissipation. If no thermally conductive adhesive is added, the space between them is considered an air gap, and air has lower thermal conductivity than thermally conductive adhesive.

[0052] Specifically, please refer to the following: Figure 3 and Figure 4As shown, the abutment plate 24 may include a first abutment plate 241 and a second abutment plate 242. The first abutment plate 241 is fixed to the base mounting portion 21 and covers the base flow channel 201. The second abutment plate 242 is fixed to the extension mounting portion 22 and covers the extension flow channel 202. High thermal conductivity grease may be applied between the contact surfaces of the electronic device and the abutment plate 24 to accelerate heat exchange efficiency.

[0053] like Figure 3 As shown, a guide plate 25 is provided inside the first heat dissipation channel 200, and the guide plate 25 is arranged along the extension direction of the first heat dissipation channel 200. By setting the guide plate 25, the coolant is guided so that the coolant can flow in the direction of the first heat dissipation channel 200, avoiding the formation of local eddies in the coolant in the first heat dissipation channel 200, so that the heat can be smoothly carried away, thereby improving the heat exchange effect of the controller housing.

[0054] Specifically, please refer to the following: Figure 4 As shown, the guide vane 25 includes a first guide vane 251, a second guide vane 252, and a third guide vane 253. The first guide vane 251 is disposed within the first section 211. The second guide vane 252 is disposed within the second section 212. The third guide vane 253 is disposed within the extended flow channel 202.

[0055] The number of the first guide vane 251, the second guide vane 252, and the third guide vane 253 are all two. Figure 4 From this vantage point, the first guide plate 251 extends downwards as a whole. The end of the first guide plate 251 bends towards the second segment 212. The starting end of the first guide plate 251 on the left bends towards the inlet 15. The starting end of the first guide plate 251 on the right is located below the inlet 15.

[0056] The second guide plate 252 extends to the left. The ends of both second guide plates 252 bend towards the first connecting port 171. The third guide plate 253 extends upward. The end of the third guide plate 253 on the left bends towards the outlet 16.

[0057] like Figure 5 As shown, the second mounting part 30 has a mounting opening 31 at one end away from the main body 10, and the mounting opening 31 is connected to the second heat dissipation channel 300. The second heat dissipation channel 300 is open, and the electronic device mounted to the mounting opening 31 is in direct contact with the coolant, so that the coolant continuously exchanges heat with the electronic device, thereby improving the heat dissipation effect of the controller housing.

[0058] Please refer to the following: Figure 6As shown, the second mounting portion 30 is provided with a mounting groove 32 for mounting a seal, and the mounting groove 32 surrounds the mounting opening 31. By providing the mounting groove 32 to mount the seal, the sealing performance is improved, and coolant leakage is prevented. In other embodiments, the electronic device can also be sealed by applying adhesive.

[0059] The second mounting portion 30 is provided with a plurality of second mounting holes 33, which allow the electronic device to be assembled to the second mounting portion 30 by means of screwing or other methods. During the process of screwing the electronic device to the second mounting portion 30, the seal is located between the electronic device and the mounting groove 32 and is gradually pressed to achieve a seal and prevent the coolant in the second heat dissipation channel 300 from leaking.

[0060] A second aspect of this application provides a controller, including a first device (not shown), a second device (not shown), and the aforementioned controller housing. The first device is assembled to a first mounting portion 20, and the second device is assembled to a second mounting portion 30. By mounting the first device and the second device on opposite sides of the controller housing, the integration level and structural compactness of the controller are improved.

[0061] The first device can be a DC-DC (Direct Current to Direct Current Converter) module or an OC-DC (On-board Charger and Direct Current) integrated module. When the first device is a DC-DC module, due to its relatively small size, only the basic flow channel 201 exchanges heat with the DC-DC module. When the first device is an OCDC integrated module, due to its relatively large size, both the basic flow channel 201 and the extended flow channel 202 exchange heat with the OCDC integrated module.

[0062] The second device can be an MCU (Micro Controller Unit) module. The MCU module is used to control the drive motor. Due to the open design of the second heat dissipation channel 300, the MCU module can achieve better heat dissipation.

[0063] The controller described in this application may be a power domain controller. A power domain controller is an intelligent controller that integrates multiple functional modules and is primarily responsible for managing and controlling the vehicle's power system, ensuring its efficient and safe operation. The specific type of controller is not limited.

[0064] A third aspect of this application provides a vehicle including the aforementioned controller. Due to the improved compactness of the controller, the vehicle's spatial layout is optimized. The vehicle can provide more space for goods and customers, improving comfort and convenience. The vehicle of this application can be a pure electric vehicle or a hybrid vehicle, and the specific type is not limited.

[0065] 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.
