[0025] Data of users, acquisition and / or use of data, etc. can be involved in embodiments of the disclosure. These aspects all comply with corresponding laws and regulations and relevant provisions. In embodiments of the disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user is aware of and confirms. Accordingly, when implementing embodiments of the disclosure, the type of data or information that can be involved, the use range, the use scenario, etc. should be notified to the user and the authorization of the user should be obtained through appropriate means according to relevant laws and regulations. The specific notification and / or authorization mode can vary according to the actual situation and application scenario, and the scope of the disclosure is not limited in this aspect.

[0026] The principles of the present disclosure will be described below with reference to several example embodiments shown in the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the description of these embodiments is only to enable those skilled in the art to better understand and implement the present disclosure, and not to limit the scope of the present disclosure in any way.

[0027] As mentioned earlier, the high vibration environment of the vehicle during driving has a significant impact on the domain controller. During driving, especially on uneven roads, the vehicle will produce intense vibrations. These vibrations will be transmitted through the vehicle structure to the domain controller, causing mechanical fatigue, loosening and even damage to internal electronic components. In addition, high-frequency vibrations can also cause solder joints on the circuit board to break, further exacerbating the risk of domain controller failure.

[0028] High temperature environment is also an important challenge for the domain controller, especially the higher requirements for the computing power of the domain controller by the automatic driving level of the vehicle. The improvement of computing power means the continuous high temperature of electronic components. High temperature can accelerate the aging of electronic components and reduce their service life. At the same time, high temperature can also cause the performance of electronic components to be unstable, resulting in drift and error, affecting the normal work of the domain controller. In addition, excessively high temperature can also cause thermal failure, causing the circuit board and components inside the domain controller to burn out.

[0029] In addition, the influence of high humidity environment on the domain controller cannot be ignored. When the vehicle drives in a humid environment, the moisture in the air will gradually penetrate into the interior of the domain controller, causing corrosion and short circuit of the circuit board. Especially in the humid and rainy areas in the south, the domain controller is more susceptible to moisture erosion, resulting in a significant reduction in its reliability and stability.

[0030] Embodiments of the present disclosure provide a housing assembly for a domain controller to solve or at least partially solve the above-mentioned problems or other potential problems existing in conventional domain controllers. The domain controller according to the embodiments of the present disclosure effectively dissipates heat for the heat-generating components of the domain controller by adopting a pair of water-cooled plates connected in series, thereby improving the system integration while ensuring the stability and reliability of the domain controller. Other benefits will be described in detail below in conjunction with the corresponding embodiments.

[0031] As will be mentioned hereinafter, the domain referred to herein, i.e., the "domain" of a vehicle, refers to the division of the electronic systems of the vehicle into different control areas according to functions, and each domain is responsible for managing a group of related subsystems and components. This division helps to simplify the complexity of the vehicle electronic electrical architecture (EEA) and improve the overall efficiency and maintainability of the system.

[0032] In the vehicle architecture, each electronic control unit (ECU) is usually responsible for a specific function, such as engine management, braking system, or infotainment system. As the functions of the vehicle increase, this distributed ECU method can result in a large number of individual control units in the system, which need complex communication and connection between them. In order to facilitate management and maintenance, automobile manufacturers have begun to adopt the concept of domain function modules referred to hereinafter. A domain function module is a more centralized control unit that integrates multiple related ECUs into a more powerful computing platform. For example, the domain function module 102 can include a power domain function module, a chassis domain function module, a safety domain function module, a cabin domain function module, an intelligent driving domain function module, a networked domain function module, and a multi-domain auxiliary function module, etc.

[0033] The domain controller according to the embodiments of the present disclosure is to fuse at least two of the above-mentioned domain function modules, thereby further simplifying the complexity of the vehicle electronic electrical architecture, improving the overall efficiency and maintainability of the system.

[0034] The concept according to the embodiments of the present disclosure will be described below in conjunction with FIGS. 1 to 3. FIG. 1 shows a perspective view of a domain controller according to an embodiment of the present disclosure, and FIGS. 2A and 2B show cross-sectional views of the domain controller along the planes of lines 2A and 2B in FIG. 1, respectively. As shown in FIGS. 1, 2A and 2B, in general, the domain controller according to the embodiments of the present disclosure includes a housing assembly 101, at least two domain function modules 102, and a water-cooling assembly 103.

[0035] The housing assembly 101 comprises a pair of housing units and a pair of inner circulation pipeline avoiding holes 1030. The pair of housing units are stacked and coupled to each other to form a pair of accommodation spaces, as shown in FIG. 2A and FIG. 2B. The pair of accommodation spaces are used to accommodate the domain function modules 102 and the water cooling assembly 103, respectively. Hereinafter, the pair of accommodation spaces will be referred to as a first accommodation space 1061 and a second accommodation space 1062, respectively.

[0036] The at least two domain function modules 102 are arranged in the at least one layer of accommodation spaces and are used to respectively implement the domain functions of at least two domains of the vehicle. For example, in some embodiments, the at least two domain function modules 102 can be at least two of the domain function modules mentioned above, i.e., the at least two domain function modules 102 include at least two of the power domain function module, the chassis domain function module, the safety domain function module, the cabin domain function module, the intelligent driving domain function module, the connected domain function module, and the multi-domain auxiliary function module.

[0037] In order to cope with the high heat brought by the fusion of multi-domain function modules, the water cooling assembly 103 according to the embodiments of the present disclosure is arranged in the at least one layer of accommodation spaces. The water cooling assembly 103 comprises a pair of water cooling plates 1031 and a heat conduction component 1033. Each water cooling plate 1031 in the pair of water cooling plates 1031 comprises a meandering flow channel 1032, a liquid inlet for allowing the cooling liquid to enter the meandering flow channel 1032, and a liquid outlet for allowing the cooling liquid to flow out of the meandering flow channel 1032.

[0038] The pair of inner circulation pipeline avoiding holes 1030 of the housing assembly of the embodiments of the present disclosure are respectively arranged on the side walls of the pair of housing units and are arranged to respectively correspond to the liquid inlet of the first water cooling plate and the liquid outlet of the second water cooling plate in the pair of water cooling plates. In this way, the inner circulation pipeline 105 can be coupled to the liquid inlet of the first water cooling plate and the liquid outlet of the second water cooling plate to allow the cooling liquid in the pair of water cooling plates to be in series communication.

[0039] In some embodiments, the liquid outlet of the first water cooling plate and the liquid inlet of the second water cooling plate can also be in communication with a pumping element. In this way, the cooling liquid in the meandering flow channel 1032 can be circulated in the meandering flow channel 1032 in the two water cooling plates 1031 by the pumping element. In addition, the meandering flow channels 1032 between the pair of water cooling plates 1031 are in series communication through the pipeline, so that the cooling liquid can be circulated in the meandering flow channels 1032 of the two water cooling plates by a set of pumping elements, reducing the number of components and control difficulty, and thereby improving the assembly efficiency.

[0040] In some embodiments, the first water-cooling plate can be a water-cooling plate in the first accommodating space 1061, and the second water-cooling plate can be a water-cooling plate in the second accommodating space 1062. In such embodiments, the cooling liquid can enter the water-cooling assembly 103 from the liquid inlet of the second water-cooling plate, and then enter the first water-cooling plate from the liquid outlet of the second water-cooling plate, and finally flow into the pumping system from the liquid outlet of the first water-cooling plate to complete the circulation of the cooling liquid. Of course, it should be understood that this is only illustrative, and the positions of the two water-cooling plates can also be interchanged. That is, for the entire water-cooling assembly 103, the liquid inlet and the liquid outlet can be exchanged according to actual conditions, and the present disclosure does not limit this.

[0041] The heat generating components 1021 of the at least two domain function modules 102 according to the embodiments of the present disclosure are respectively arranged on at least one side of the pair of water-cooling plates 1031, and the heat conduction components 1033 are located between the water-cooling plates 1031 and the heat generating components 1021 (for example, processors). In this way, the water-cooling plates 1031 can effectively dissipate heat for the plurality of domain control modules, thereby improving the stability and reliability of the domain controller 100.

[0042] The specific structure of the pair of housing units will be described below in conjunction with FIGS. 1, 2A and 2B. For ease of description, the pair of housing units will be referred to as a first housing unit 1063 and a second housing unit 1064 hereinafter. In some embodiments, the first housing unit 1063 can include a first housing assembly 1011 and a first cover 1012. The first housing assembly 1011 includes a first bottom shell 1066 and a pair of first side walls 1065 extending from the first bottom shell 1066 toward a first side. The first cover 1012 is arranged to be coupled to the pair of first side walls 1065 of the first housing assembly 1011 from the first side to form a first accommodating space 1061 in the at least one layer of accommodating spaces. The first accommodating space 1061 is used to accommodate a first water-cooling plate in the pair of water-cooling plates 1031. Meanwhile, the first accommodating space 1061 also accommodates part of the domain function modules in the at least two domain control modules 102.

[0043] For example, in some embodiments, the plurality of domain function modules can be arranged on both sides of the first water-cooling plate, and the corresponding heat generating components 1021 are coupled to the water-cooling plates 1031 through the heat conduction components 1033 to effectively dissipate heat and cool down.

[0044] In some embodiments, the second housing unit 1064 includes a second housing assembly 1013 and a second cover 1014. The second housing assembly 1013 includes a second bottom shell 1019 and a pair of second side walls 1010 extending from the second bottom shell 1019 toward a second side. The second bottom shell 1019 is coupled to the second side of the first bottom shell 1066.

[0045] As shown in FIG. 3, the second housing assembly 1013 can be formed with a support portion 1020. The support portion 1020 can be supported at a predetermined position when the domain controller 100 is horizontally placed, thereby facilitating installation and fixation of the domain controller. In this context, when the domain controller 100 is horizontally placed, the first side can represent the upper side and the second side can represent the lower side. Of course, it should be understood that when the domain controller is installed or fixed in other orientations, the first side and the second side respectively represent the corresponding orientations, which will not be described again in the following.

[0046] The second cover 1014 is arranged to be coupled to the pair of second side walls 1010 of the second housing assembly 1013 from the second side, to form a second accommodation space 1062 for accommodating a second water-cooling plate of the pair of water-cooling plates 1031. Meanwhile, similar to the first accommodation space 1061, the second accommodation space 1062 can also accommodate part of the domain function modules of the at least two domain control modules 102. For example, in some embodiments, a plurality of domain function modules 102 can be arranged on both sides of the second water-cooling plate, and the corresponding heat generating components 1021 are coupled to the water-cooling plate 1031 through the heat conduction components 1033 for effective heat dissipation and cooling.

[0047] As can be seen from the above description, the at least two domain function modules 102 can include a plurality of domain function modules arranged in the first accommodation space 1061 and respectively located on the first side and the second side of the first water-cooling plate, and another plurality of domain function modules arranged in the second accommodation space 1062 and respectively located on the first side and the second side of the second water-cooling plate.

[0048] In some embodiments, the first housing unit 1063 further includes a pair of first auxiliary cover plates 1015. The pair of first auxiliary cover plates 1015 are arranged between the first cover 1012 and the first bottom shell 1066, and respectively located between the end portions of the pair of first side walls 1065. The pair of first auxiliary cover plates 1015 include a plurality of first accommodation holes 1017 through which part of the connection ports of the at least two domain function modules 102 pass. These connection ports can include, but are not limited to, peripheral component interconnect express (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power supply ports, controller area network bus (CAN) ports, etc. These ports can be connected with corresponding data lines or power supply lines, thereby being connected with external devices or other domain function modules within the domain controller.

[0049] In some embodiments, the second housing unit 1064 further includes a second auxiliary cover plate 1016. The second auxiliary cover plate 1016 is arranged between the second cover 1014 and the second bottom shell 1019, and between the ends of the pair of second side walls 1010, thereby sealing the opening between the ends of the pair of second side walls 1010. The second auxiliary cover plate 1016 includes a plurality of second relief holes 1018 through which a portion of the connection ports of the at least two domain function modules pass. Similar to the first relief holes 1017, these ports can include, but are not limited to, Peripheral Component Interconnect Express (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power supply ports, Controller Area Network bus (CAN) ports, etc.
