[0002] The in-vehicle domain controller has a high integration level and a large heat density, and usually adopts a water-cooling scheme for heat dissipation. The cooling structure mainly consists of a water-cooling top cover, a main board, and a bottom cover. The water-cooling top cover is composed of a water nozzle, a water-cooling cavity, and a cover plate. The water-cooling cavity is the main structure of the water-cooling scheme. On the one hand, a heat dissipation boss is designed on the side close to the main board to exchange heat with the heat dissipation chips on the main board. On the other hand, a flow channel structure is designed on the side far from the main board to take away heat through water flow. When the layouts and package sizes of the heat dissipation chips are inconsistent, it will lead to inconsistent corresponding heat dissipation boss structures, and due to the difference in thermal power consumption, the design of the turbulator columns inside the flow channel will also be different.

[0028] The following refers to Figure 1 - Figure 2 Describe the domain controller structure 100 according to an embodiment of the present utility model. By arranging a flow channel cover plate 5 in the cooling cavity 2, and making the flow channel cover plate 5 form a heat exchange convex portion 51 to exchange heat with the control main board 4, and making the flow channel cover plate 5 form a flow disturbance convex portion 52 to guide the flow of the coolant in the cooling flow channel 21, the reliability of cooling the control main board 4 is improved. Thus, only by designing a flow channel cover plate 5 that matches different control main boards 4 can the domain controller structure 100 achieve the cooling function for different control main boards 4, increasing the versatility of the domain controller structure 100, and without the need to re-open the mold for the cooling cavity 2, which can effectively shorten the development review cycle, reduce the development and manufacturing costs, and is beneficial to improving user satisfaction.

[0029] As Figure 1 shown, the domain controller structure 100 according to an embodiment of the present utility model includes: a base 1, a cooling cavity 2, and a flow channel cover plate 5.

[0030] The cooling cavity 2 is connected to the base 1 and together defines an installation cavity 3 for installing the control main board 4, and a cooling flow channel 21 is formed in the cooling cavity 2.

[0031] Specifically, the base 1 is disposed at the bottom of the domain controller structure 100 and is used to support other components within the domain controller structure 100. Meanwhile, a control main board 4 is also disposed between the cooling cavity 2 and the base 1. The control main board 4 is an important component for the domain controller to function. Setting the cooling cavity 2 above the base 1 and connecting it to the base 1 can make the domain controller structure 100 an integral whole, thereby enhancing the overall structural strength of the domain controller structure 100, and enabling the cooling cavity 2 and the base 1 to jointly form an installation cavity 3 for installing the control main board 4, that is, the installation cavity 3 can provide an installation position for the control main board 4 to achieve the installation of the control main board 4.

[0032] In addition, the cooling cavity 2 is used to allow the coolant to flow inside it to exchange heat with the control main board 4, thereby realizing the cooling function of the control main board 4. And a cooling flow channel 21 is formed in the cooling cavity 2. The cooling flow channel 21 is used to allow the coolant to flow inside it, that is, the heat dissipated by the control main board 4 can be taken away by the flow of the coolant in the cooling flow channel 21 to achieve the cooling function of the control main board 4. Among them, the coolant can be cooling water.

[0033] The flow channel cover plate 5 is installed on the side wall of the cooling cavity 2 close to the installation cavity 3 and is distributed opposite to the control main board 4, and the flow channel cover plate 5 is formed with a heat exchange convex part 51 extending towards the control main board 4 and / or a flow disturbing convex part 52 extending into the cooling flow channel 21.

[0034] Specifically, the flow channel cover plate 5 is used to further realize the cooling function of the control main board 4. Setting the flow channel cover plate 5 inside the cooling cavity 2 can achieve the installation of the flow channel cover plate 5, and setting the flow channel cover plate 5 on the side wall close to the installation cavity 3 can set the flow channel cover plate 5 at a position close to the control main board 4, so as to facilitate the cooling function of the control main board 4 through the flow channel cover plate 5, and making the flow channel cover plate 5 and the control main board 4 distributed opposite to each other can make the flow channel cover plate 5 face the control main board 4 directly, so as to increase the facing area between the flow channel cover plate 5 and the control main board 4 and enhance the cooling effect of the control main board 4 through the flow channel cover plate 5.

[0035] At the same time, the flow channel cover plate 5 is formed with a heat exchange convex part 51. The heat exchange convex part 51 is used to exchange heat with the control main board 4, that is, the flow channel cover plate 5 can realize the heat exchange with the control main board 4 through the heat exchange convex part 51, and further can realize the cooling function of the control main board 4. And extending the heat exchange convex part 51 towards the control main board 4 can make the heat exchange convex part 51 extend downward from the flow channel cover plate 5 to approach the control main board 4, facilitating the heat exchange between the heat exchange convex part 51 and the control main board 4.

[0036] In addition, the flow channel cover plate 5 can be formed with flow disturbance convex portions 52 for guiding the flow of the coolant. That is, the flow channel cover plate 5 can control the flow direction of the coolant in the cooling flow channel 21 through the flow disturbance convex portions 52, thereby improving the reliability of cooling the control main board 4 with the coolant. And by extending the flow disturbance convex portions 52 into the cooling flow channel 21, the flow disturbance convex portions 52 can extend upward from the flow channel cover plate 5 to approach the coolant, facilitating the flow disturbance convex portions 52 to guide the flow of the coolant and improving the reliability of cooling the control main board 4 with the coolant. Also, the coolant can be separated from the control main board 4 by the flow channel cover plate 5 to prevent the control main board 4 from being damaged and failing under the action of the coolant. Thus, only by designing the flow channel cover plate 5 matching different control main boards 4 can the domain controller structure 100 realize the cooling function for different control main boards 4, increasing the versatility of the domain controller structure 100, without the need to re-open the mold for the cooling cavity 2, effectively shortening the development review cycle, reducing the development and manufacturing costs, and being beneficial to improving user satisfaction.

[0037] It should be noted that by respectively arranging the heat exchange convex portion 51 and the flow disturbance convex portion 52 on both sides of the flow channel cover plate 5, interference between them can be avoided, and the reliability of heat exchange between the heat exchange convex portion 51 and the control main board 4 and the reliability of the flow disturbance convex portion 52 for guiding the coolant can be ensured.

[0038] Thus, by providing the base 1, other components within the domain controller structure 100 can be supported. By jointly defining an installation cavity 3 with the cooling cavity 2 for installing the control main board 4, and forming a cooling flow channel 21 in the cooling cavity 2 to realize the cooling function for the control main board 4 through the flow of the coolant in the cooling flow channel 21. In addition, a flow channel cover plate 5 is arranged in the cooling cavity 2, and the flow channel cover plate 5 is formed with a heat exchange convex portion 51 and a flow disturbance convex portion 52. The heat exchange convex portion 51 is used for heat exchange with the control main board 4, and the flow disturbance convex portion 52 is used for guiding the flow of the coolant in the cooling flow channel 21.

[0039] According to the domain controller structure 100 of the embodiment of the present invention, by arranging the flow channel cover plate 5 in the cooling cavity 2, and forming the heat exchange convex portion 51 on the flow channel cover plate 5 to realize heat exchange with the control main board 4, and forming the flow disturbance convex portion 52 on the flow channel cover plate 5 to guide the flow of the coolant in the cooling flow channel 21, the reliability of cooling the control main board 4 is improved. Thus, only by designing the flow channel cover plate 5 matching different control main boards 4 can the domain controller structure 100 realize the cooling function for different control main boards 4, increasing the versatility of the domain controller structure 100, without the need to re-open the mold for the cooling cavity 2, effectively shortening the development review cycle, reducing the development and manufacturing costs, and being beneficial to improving user satisfaction.

[0040] In some embodiments, the domain controller structure 100 further includes an outer cover plate 6, which is installed on the side wall of the cooling channel 21 away from the control main board 4, and the outer cover plate 6 and the channel cover plate 5 are spaced apart and oppositely distributed on both sides of the cooling channel 21.

[0041] Specifically, the outer cover plate 6 is used to enclose the cooling cavity 2 from the outside to improve the reliability of the coolant flowing in the cooling channel 21, prevent the coolant from flowing out, resulting in the inability to cool the control main board 4 or reduce the cooling effect of the control main board 4. By setting the outer cover plate 6 on the side wall of the cooling channel 21, the outer cover plate 6 can be attached to the side wall of the cooling channel 21 to effectively prevent the coolant from flowing out. And by setting the outer cover plate 6 on the side of the cooling channel 21 away from the control main board 4, the outer cover plate 6 and the control main board 4 can be spaced apart on both sides of the cooling channel 21 to avoid interference between the two, resulting in the inability to install the control main board 4 or the outer cover plate 6, and further resulting in the inability to cool the control main board 4.

[0042] Moreover, by spacing the outer cover plate 6 and the channel cover plate 5 apart on both sides of the cooling channel 21, the channel cover plate 5 and the control main board 4 can be arranged on the same side of the cooling channel 21, so that the channel cover plate 5 can approach the control main board 4, facilitating the cooling of the control main board 4 through the channel cover plate 5, and avoiding interference between the outer cover plate 6 and the channel cover plate 5, resulting in the inability to cool the control main board 4. And by arranging the outer cover plate 6 and the channel cover plate 5 oppositely distributed on both sides of the cooling channel 21, the outer cover plate 6 and the channel cover plate 5 can be respectively arranged on two opposite side walls of the cooling channel 21 to ensure the reliability of the coolant flowing in the cooling channel 21.

[0043] In some embodiments, the cooling cavity 2 is formed with a first installation opening 22 and a second installation opening 23. The outer cover plate 6 is installed at the first installation opening 22, and the channel cover plate 5 is installed at the second installation opening 23. The opening area of the first installation opening 22 is larger than that of the second installation opening 23.

[0044] Specifically, both the first installation opening 22 and the second installation opening 23 can be used to install components inside the domain controller structure 100. By installing the outer cover plate 6 at the first installation opening 22, the first installation opening 22 can provide an installation position for the outer cover plate 6, and thus the outer cover plate 6 can be installed inside the cooling cavity 2 through the first installation opening 22. By installing the channel cover plate 5 at the second installation opening 23, the second installation opening 23 can provide an installation position for the channel cover plate 5, and thus the channel cover plate 5 can be installed inside the cooling cavity 2 through the second installation opening 23. Moreover, by making the opening area of the first installation opening 22 larger than that of the second installation opening 23, the area of the outer cover plate 6 can be made larger than that of the channel cover plate 5, so that the outer cover plate 6 can be directly opposite to channel cover plates 5 of different sizes to cool different control main boards 4.

[0045] In some embodiments, there are multiple heat exchange protrusions 51, and the multiple heat exchange protrusions 51 are spaced apart and distributed on the side of the flow channel cover plate 5 facing the control main board 4.

[0046] Specifically, the heat exchange protrusions 51 are used to achieve heat exchange with the control main board 4. By setting the heat exchange protrusions 51 to be multiple, heat exchange can be carried out with the control main board 4 simultaneously through the multiple heat exchange protrusions 51, so as to improve the heat exchange efficiency, and further improve the efficiency of cooling the control main board 4. At the same time, by spacing the multiple heat exchange protrusions 51 apart, there will be a certain gap between the multiple heat exchange protrusions 51, which is beneficial to the heat dissipation of the heat exchange protrusions 51 and improves the reliability of heat exchange with the control main board 4. Moreover, by arranging the multiple heat exchange protrusions 51 on the side facing the control main board 4, the multiple heat exchange protrusions 51 can all approach the control main board 4, so as to facilitate the simultaneous heat exchange of the multiple heat exchange protrusions 51 with the control main board 4 and effectively improve the efficiency of cooling the control main board 4.

[0047] In some embodiments, there are multiple flow disturbance protrusions 52, and the multiple flow disturbance protrusions 52 are spaced apart and distributed on the side of the flow channel cover plate 5 facing the inside of the cooling flow channel 21.

[0048] Specifically, the flow disturbance protrusions 52 are used to guide the flow of the coolant in the cooling flow channel 21. By setting the flow disturbance protrusions 52 to be multiple, the flow of the coolant can be guided jointly by the multiple flow disturbance protrusions 52, so as to improve the reliability of guiding the flow of the coolant. At the same time, by spacing the multiple flow disturbance protrusions 52 apart, there will be a certain gap between the multiple flow disturbance protrusions 52, which is convenient for the flow of the coolant and improves the reliability of using the coolant to cool the control main board 4. Moreover, by arranging the multiple flow disturbance protrusions 52 on the side facing the inside of the cooling flow channel 21, the multiple flow disturbance protrusions 52 can all approach the coolant, so as to facilitate the joint guiding of the flow of the coolant by the multiple flow disturbance protrusions 52 and effectively improve the reliability of using the coolant to cool the control main board 4.

[0049] In some embodiments, the cooling cavity 2 is provided with a water inlet pipe 24 and a water outlet pipe 25 communicating with the cooling flow channel 21, and at least part of the coolant at the water inlet pipe 24 is adapted to flow towards the water outlet pipe 25 through the gap between two adjacent flow disturbance protrusions 52.

[0050] Specifically, the cooling channel 21 is used to allow the coolant to flow inside it, so as to take away the heat dissipated by the control main board 4 during the flowing process. A water inlet pipe 24 is provided on the cooling cavity 2, and the water inlet pipe 24 is communicated with the cooling channel 21, that is, the coolant can enter the cooling channel 21 from the water inlet pipe 24 and flow in the cooling channel 21 to exchange heat with the control main board 4. At the same time, a water outlet pipe 25 is also provided on the cooling cavity 2, and the water outlet pipe 25 is also communicated with the cooling channel 21, that is, the coolant in the cooling channel 21 can flow out from the water outlet pipe 25 to take away the heat on the control main board 4, so that the water inlet pipe 24, the cooling channel 21 and the water outlet pipe 25 can form a one-way circulation of the coolant, and the cooling efficiency of the control main board 4 can be improved.

[0051] Moreover, at least part of the coolant at the water inlet pipe 24 can flow from the gap between two adjacent flow disturbance convex parts 52 to the water outlet pipe 25, that is, the flow of the coolant in the cooling channel 21 can be guided by the flow disturbance convex parts 52, and it can be ensured that at least part of the coolant is used to cool the control main board 4, and the reliability of using the coolant to cool the control main board 4 can be improved.

[0052] Among them, it should be noted that, as Figure 1 - Figure 2 shown, the water inlet pipe 24 and the water outlet pipe 25 can be arranged on the same side of the cooling cavity 2, so that the distance between the water inlet pipe 24 and the water outlet pipe 25 is relatively close, which is convenient for maintaining the water inlet and outlet on the same side, and the space utilization rate can be improved.

[0053] In some embodiments, there are multiple control main boards 4, and the multiple control main boards 4 are distributed at intervals in the installation cavity 3.

[0054] Specifically, the control main board 4 is used to collect, process and analyze the data from vehicle sensors and actuators to achieve precise control of various vehicle functions. The control main board 4 can be set to be multiple, so as to process the data simultaneously through multiple control main boards 4, and the processing speed of the data can be improved. Moreover, by arranging the multiple control main boards 4 in the installation cavity 3, the installation of the multiple control main boards 4 can be realized, and the multiple control main boards 4 are spaced apart to avoid interference between the multiple control main boards 4, resulting in the control main board 4 being unable to work properly or the control main board 4 being unable to be installed.

[0055] Among them, there are multiple flow channel covers 5, and the multiple flow channel covers 5 are distributed in one-to-one correspondence with the multiple control main boards 4.

[0056] Specifically, the flow channel cover plate 5 is used to cool the control main board 4. Multiple flow channel cover plates 5 can be provided to cool the control main board 4 simultaneously through the multiple flow channel cover plates 5, and the multiple flow channel cover plates 5 are distributed in one-to-one correspondence with the multiple control main boards 4. That is, for each control main board 4, a flow channel cover plate 5 is provided correspondingly to cool it, which can improve the reliability of cooling the control main board 4 through the flow channel cover plate 5.

[0057] In some embodiments, the flow channel cover plate 5 and the cooling cavity 2 are connected by friction stir welding, brazing or bonding.

[0058] Specifically, connecting the flow channel cover plate 5 and the cooling cavity 2 can facilitate the spoiler protrusion 52 on the flow channel cover plate 5 to extend into the cooling flow channel 21 to guide the flow of the coolant, improving the reliability of cooling the control main board 4. The flow channel cover plate 5 and the cooling cavity 2 can be connected by friction stir welding, brazing or gluing to enhance the connection strength and reliability between the two, which can further improve the reliability of using the flow channel cover plate 5 to cool the control main board 4.

[0059] And it should be noted that, as Figure 1 - Figure 2 shown, a connecting seat 7 is respectively connected to the four corners of the base 1. The connecting seat 7 is used to connect to the vehicle, so that the domain controller structure 100 can be installed on the vehicle by connecting the connecting seat 7 to the vehicle, and the connection reliability and stability between the domain controller structure 100 and the vehicle can be improved.
