Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of domain controller, in particular to a liquid-cooled domain controller. BACKGROUND

[0002] With the rapid development of vehicle intelligence and networking, the computing power requirement of domain controllers is rapidly increasing, and the demand for liquid-cooled domain controllers is also increasing. The liquid-cooled domain controller mainly cools the electronic control unit in it through the cooling liquid to prevent the generated large heat from being dissipated, causing damage to the electronic control unit device.

[0003] The existing liquid-cooled domain controller often has the phenomenon of cooling liquid overflow due to plug aging and other problems. Generally, a hole is opened on the vehicle chassis sheet metal, and a nozzle is arranged on the liquid-cooled domain controller to communicate with the hole, and the overflow cooling liquid is discharged through the nozzle. However, the traditional nozzle is not reasonably arranged and the sealing is not in place, and the cooling liquid often leaks back, causing short circuit of each electronic control unit in the domain controller and affecting user experience. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a liquid-cooled domain controller with reasonable structure and complete sealing, which can prevent the overflow cooling liquid from leaking back.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A liquid-cooled domain controller for mounting on a mounting plate of an automobile chassis, the liquid-cooled domain controller comprising:

[0007] a housing having a mounting surface arranged horizontally towards the mounting plate, and the housing having a liquid cooling flow channel inside;

[0008] a circuit board mounted in the housing and capable of dissipating heat through the liquid cooling flow channel;

[0009] an inlet and outlet pipe mounted on the mounting surface and communicating with the liquid cooling flow channel, and the axis of the inlet and outlet pipe being arranged vertically to the mounting surface; wherein one end of the inlet and outlet pipe away from the housing penetrates the mounting plate;

[0010] a sealing member sleeved around the circumference of the inlet and outlet pipe and capable of abutting against the mounting plate to seal the gap between the inlet and outlet pipe and the mounting plate.

[0011] It can be understood that the application can effectively prevent the backflow of the cooling liquid by arranging the inlet and outlet pipes on the mounting surface and in communication with the liquid cooling flow channel, and arranging the axis of the inlet and outlet pipes perpendicular to the mounting surface, so that the discharged cooling liquid can directly flow in the vertical direction of the mounting surface. At the same time, the gap between the inlet and outlet pipes and the mounting plate is sealed by the sealing member arranged around the inlet and outlet pipes, so that part of the backflow of the cooling liquid can be prevented from entering the gap, and the short circuit of each electronic control unit in the liquid cooling domain controller caused by contacting the cooling liquid can be further prevented.

[0012] In one of the embodiments, the mounting surface is provided with a mounting seat, and the inlet and outlet pipes are arranged on the mounting seat.

[0013] The mounting seat is provided with a first clamping groove in the circumferential direction, the sealing member is provided with a sleeving hole, and the wall surface of the sleeving hole is provided with a first protrusion. The sealing member is sleeved on the mounting seat through the sleeving hole, and the first protrusion is clamped into the first clamping groove.

[0014] It can be understood that the first protrusion arranged on the sealing member is the first sealing barrier of the gap between the inlet and outlet pipes and the mounting plate. The first protrusion can change the direction of part of the backflow of the cooling liquid, so as to prevent it from entering the mounting plate. By clamping the first protrusion into the first clamping groove, the connection between the sealing member and the mounting seat is more firm, so as to prevent the sealing member from falling off and failing to play a sealing role.

[0015] In one of the embodiments, the inlet and outlet pipes include an inlet pipe and an outlet pipe, and the inlet pipe and the outlet pipe are arranged at intervals.

[0016] The mounting seat is provided with a second clamping groove between the inlet pipe and the outlet pipe, and the sleeving hole is provided with a clamping arm. The clamping arm can be clamped and connected with the second clamping groove.

[0017] It can be understood that the cooling liquid can enter the liquid cooling flow channel from the inlet pipe, take out the heat of the domain controller, and then flow out from the outlet pipe. The interval arrangement of the inlet pipe and the outlet pipe can make the cooling liquid enter or flow out in an orderly manner, and increase the heat dissipation efficiency of the liquid cooling controller. The clamping arm and the second clamping groove are clamped and connected, so that the connection structure of the inlet and outlet pipes and the sealing member is more stable, and the sealing of the gap between the inlet and outlet pipes and the mounting plate by the sealing member is further ensured.

[0018] In one of the embodiments, the mounting seat is provided with a third clamping groove in the circumferential direction, and the wall surface of the sleeving hole is provided with a second protrusion. The second protrusion can be clamped and connected with the third clamping groove.

[0019] The first clamping groove, the third clamping groove and the second clamping groove are not in the same plane.

[0020] It can be understood that the second protrusion is a second sealing barrier of the gap between the inlet and outlet pipe and the mounting plate, and when the part of the backflow cooling liquid enters the gap through the first protrusion, the second protrusion can act to avoid the seepage cooling liquid from entering again, further improving the sealing performance of the connection structure at this position, and the second protrusion is connected with the third clamping groove to limit the sealing member, so that the sealing member is not easy to fall off.

[0021] In one of the embodiments, the sealing member is provided with an annular protrusion on a surface facing the mounting plate, and the annular protrusion is arranged around the inlet and outlet pipe.

[0022] It can be understood that the annular protrusion can form a defense line in the radial direction of the inlet and outlet pipe to prevent the backflow of the cooling liquid into the gap, and the annular protrusion is arranged at this position, so that under the premise of the same thickness, the annular protrusion is equivalent to excavating part of the volume at the lower end, so that the volume of the sealing member is reduced relative to the sealing member with the same thickness. The side surface of the sealing member is laterally abutted by the mounting plate, so that the sealing member is deformed under extrusion and applies a reaction force to the mounting plate, thereby achieving a sealing effect. Since the annular protrusion reduces the volume of the sealing member, the deformation amount is also reduced, and the reaction force received by the mounting plate is also reduced, thereby avoiding damage to the mounting plate.

[0023] In one of the embodiments, the number of annular protrusions is at least two, and the at least two annular protrusions are arranged at intervals in the radial direction of the inlet and outlet pipe.

[0024] It can be understood that the at least two annular protrusions form at least two defense lines in the radial direction of the inlet and outlet pipe to further prevent the backflow of the cooling liquid from seeping into the gap between the sealing member and the mounting seat.

[0025] In one of the embodiments, the liquid cooling area controller further comprises a heat conduction table, which is arranged in the shell and located at the liquid cooling flow channel, and is in contact with the circuit board for heat conduction.

[0026] It can be understood that the heat on the circuit board can be completely transferred to the heat conduction table, and then the heat transferred to the heat conduction table can be dissipated in time through the cooling liquid in the liquid cooling flow channel, so as to ensure that the liquid cooling area controller has good heat dissipation function.

[0027] In one of the embodiments, the circuit board and the heat conduction table are connected by a heat conduction adhesive; and / or, the circuit board and the shell are in contact through the heat conduction adhesive.

[0028] It can be understood that the heat-conducting glue can quickly transfer the heat of the heating circuit board to the heat-conducting table and the shell, so as to improve the heat dissipation efficiency of the circuit board and avoid damage of the circuit due to untimely heat dissipation; and the heat-conducting glue can shield electromagnetic waves and form a circuit closed loop with other components of the liquid cooling domain controller, so as to ensure that the liquid cooling domain controller can work normally.

[0029] In one of the embodiments, a turbulence protrusion is arranged in the liquid cooling flow channel, and the position of the turbulence protrusion corresponds to the position of the heat-conducting table.

[0030] It can be understood that the turbulence protrusion can make the cooling liquid turbulent in the liquid cooling flow channel, so that the heat in the liquid cooling domain controller can fully contact with the cooling liquid and be quickly dissipated.

[0031] In one of the embodiments, the inlet and outlet pipe and the shell are integrally formed by injection molding.

[0032] It can be understood that the injection molding of the inlet and outlet pipe and the shell can reduce the weight of the liquid cooling domain controller, optimize the structural configuration, and the integrated structure ensures the stability of the connection structure of the inlet and outlet pipe and the shell, and reduces the gap between the inlet and outlet pipe and the shell, so as to further prevent the backflow of the cooling liquid into the liquid cooling domain controller and increase the sealing property of the structure.

[0033] Compared with the prior art, the liquid cooling domain controller sets the inlet and outlet pipe and the sealing element, installs the inlet and outlet pipe on the mounting surface and communicates with the liquid cooling flow channel, so that the cooling liquid in the liquid cooling flow channel can be discharged through the inlet and outlet pipe, and the axis of the inlet and outlet pipe is arranged vertically to the mounting surface, so that the discharged cooling liquid can directly flow to the vertical direction of the mounting surface, which can effectively prevent the backflow of the cooling liquid; at the same time, the sealing element is arranged around the inlet and outlet pipe, so as to seal the gap between the inlet and outlet pipe and the mounting plate, which can avoid that part of the backflow of the cooling liquid enters the gap, and further prevent the short circuit of each electric control unit in the liquid cooling domain controller due to contact with the cooling liquid.

[0047] Please refer to Figures 1 to 6 The present application provides a liquid cooling domain controller 100, which is applied to the field of intelligent vehicles, mainly used for heat dissipation of electric control unit devices inside the vehicle, and through reasonable structure setting and sealing, the phenomenon of backflow of cooling liquid is avoided, and the cooling liquid is prevented from leaking back into the electric control unit devices, so as to avoid damage and improve user experience.

[0048] As shown in Figure 1 and Figure 6 The liquid cooling domain controller 100 is used for being installed on the mounting plate 101 of the automobile chassis, comprising a shell 10, a circuit board 20, an inlet and outlet pipe 30 and a sealing member 40; the shell 10 has a mounting surface 11 arranged horizontally towards the mounting plate 101, and the interior of the shell 10 has a liquid cooling flow channel 12; the circuit board 20 is installed in the shell 10 and can dissipate heat through the liquid cooling flow channel 12; the inlet and outlet pipe 30 is installed on the mounting surface 11 and communicates with the liquid cooling flow channel 12, and the axis of the inlet and outlet pipe 30 is arranged vertically to the mounting surface 11; wherein, the end of the inlet and outlet pipe 30 away from the shell 10 penetrates the mounting plate 101; the sealing member 40 is sleeved on the circumference of the inlet and outlet pipe 30 and can abut against the mounting plate 101 to seal the gap between the inlet and outlet pipe 30 and the mounting plate 101, and the mounting plate 101 is the body panel of the vehicle.

[0049] It needs to be explained that the existing related technology is usually to set the axis of the inlet and outlet pipe 30 parallel to the mounting surface 11, so that the flow direction of the cooling liquid when discharged is also parallel to the mounting surface 11, which causes the discharged cooling liquid to be more prone to backflow and enter the liquid cooling area controller 100 from the gap between the inlet and outlet pipe 30 and the mounting plate 101, thereby causing the circuit board 20 inside to be in contact with the cooling liquid and short-circuit, affecting the user experience. Therefore, in the present application, the inlet and outlet pipe 30 with the axis perpendicular to the mounting surface 11 is set, so that the cooling liquid discharged from the liquid cooling channel 12 can directly flow in the vertical direction of the mounting surface 11, thereby effectively preventing the cooling liquid from flowing back into the gap between the inlet and outlet pipe 30 and the mounting plate 101; at the same time, the sealing member 40 is provided, and the sealing member 40 is sleeved on the circumference of the inlet and outlet pipe 30, so that the gap between the inlet and outlet pipe 30 and the mounting plate 101 can be directly sealed by the sealing member 40, thereby avoiding the cooling liquid from flowing back to the gap and contacting the circuit board 20, causing the circuit board 20 to short-circuit. The setting mode, through the improvement and perfection of the structure, makes the cooling liquid flowing out of the liquid cooling area controller 100 not to seep in and damage its normal operation, thereby improving the user's experience.

[0050] Here, the liquid cooling channel 12 in the liquid cooling area controller 100 is provided with a cover plate 102 to close the liquid cooling channel 12, so that the cooling liquid can flow through the liquid cooling channel 12 and carry away the heat generated by the circuit board 20 during operation.

[0051] As shown in Figure 1 and Figure 2 , the liquid cooling channel 12 is provided with a turbulence protrusion 121 to cause the cooling liquid to flow turbulently on the liquid cooling channel and fully contact the heat generated by the circuit board 20 to achieve better heat dissipation effect.

[0052] Further, the liquid cooling area controller 100 further comprises a heat-conducting table (not shown in the figure), which is integrally formed in the housing 10 and located at the back of the liquid cooling channel 12, and is in contact with the chip on the circuit board 20 for heat conduction; at the same time, the position of the turbulence protrusion 121 corresponds to the position of the heat-conducting table, and the chip between the circuit board 20 and the heat-conducting table, and the circuit board 20 and the housing 10 can be in soft contact through the heat-conducting adhesive. In this way, the heat-conducting table can conduct the heat generated by the chip on the circuit board 20 to the liquid cooling channel 12, and the cooling liquid enters the liquid cooling channel 12 from the inlet and outlet pipe 30 and fully contacts it, carrying out the heat to achieve rapid cooling.

[0053] As preferred, the inlet and outlet pipe 30 is integrally formed with the shell 10 by injection molding. It can be understood that the injection molding arrangement can reduce the overall weight of the liquid cooling area controller 100, optimize the structural configuration, and the integrated structure ensures the stability of the connection structure of the inlet and outlet pipe 30 and the shell 10, and reduces the gap between the inlet and outlet pipe 30 and the shell 10, to increase the sealing of the structure, and further prevent the cooling liquid from flowing back into the liquid cooling area controller 100.

[0054] As shown in Figures 3 to 6 , the mounting surface 11 is provided with a mounting seat 31, the inlet and outlet pipe 30 is mounted on the mounting seat 31, and the mounting seat 31 is provided with a first clamping groove 311 in the circumferential direction, the first clamping groove 311 can be connected with the sealing element 40 to form the first sealing barrier of the gap between the inlet and outlet pipe 30 and the mounting plate 101, to prevent the cooling liquid from flowing back and entering the inside of the liquid cooling area controller 100 through the gap, causing short circuit of each electric control unit in the circuit board 20.

[0055] For example, the inlet and outlet pipe 30 includes an inlet pipe 32 and an outlet pipe 33, and the inlet pipe 32 and the outlet pipe 33 are spaced apart; the mounting seat 31 is provided with a second clamping groove 312 between the inlet pipe 32 and the outlet pipe 33, for clamping and fixing the sealing element 40, to avoid the sealing element 40 from shaking in the horizontal direction of the liquid cooling area controller 100.

[0056] Further, the mounting seat 31 is further provided with a third clamping groove 313 in the circumferential direction, the third clamping groove 313 can be connected with the sealing element 40 to form the second sealing barrier of the gap between the inlet and outlet pipe 30 and the mounting plate 101, to further prevent the cooling liquid from flowing back and entering the inside of the liquid cooling area controller 100 through the gap, and protect each electric control unit in the circuit board 20.

[0057] Here, the first clamping groove 311 and the third clamping groove 313 are not in the same plane as the second clamping groove 312, the first clamping groove 311 and the third clamping groove 313 can limit the sealing element 40 in the vertical direction of the liquid cooling area controller 100, to avoid the sealing element 40 from falling off, and the second clamping groove 312 limits the sealing element 40 in the horizontal direction of the liquid cooling area controller 100, to prevent the sealing element 40 from shaking horizontally, causing the sealing to be not tight. Through such a setting mode, the stability of the fixing structure of the sealing element 40 can be improved, so that the sealing element 40 can always be with the mounting seat 31, to ensure the sealing of the sealing element 40.

[0058] As shown in Figure 1 and Figure 6As shown, the sealing member 40 is provided with a sleeving hole 41, and a first protrusion 411 is arranged on the wall surface of the sleeving hole 41. The sealing member 40 is sleeved on the mounting seat 31 through the sleeving hole 41, and the first protrusion 411 is simultaneously clamped into the first clamping groove 311. The first protrusion 411 can change the direction of part of the backflowing cooling liquid, thereby preventing it from entering the mounting plate 101. By clamping the first protrusion 411 into the first clamping groove 311, the connection between the sealing member 40 and the mounting seat 31 is more secure, thereby preventing the sealing member 40 from being pulled out of the mounting seat 31 in the vertical direction, ensuring the stability of the structural connection, and enabling the sealing member 40 to function normally.

[0059] As shown in Figure 5 and Figure 6 , a clamping arm 412 is arranged in the sleeving hole 41, which can be clamped and connected with the second clamping groove 312, making the connection structure of the inlet and outlet pipe 30 and the sealing member 40 more stable, and further ensuring the sealing of the sealing member 40 on the gap between the inlet and outlet pipe 30 and the mounting plate 101.

[0060] Further, a second protrusion 413 is arranged on the wall surface of the sleeving hole 41, which can be clamped and connected with the third clamping groove 313, avoiding the backflow of cooling liquid leaked from outside the mounting plate 101 into the inside of the mounting plate 101, and further improving the sealing performance of the connection structure at this position.

[0061] As shown in Figures 4 to 6 , a ring-shaped protrusion 42 is arranged on the surface of the sealing member 40 facing the mounting plate 101, which surrounds the inlet and outlet pipe 30, forming a defense line in the radial direction of the inlet and outlet pipe 30 to prevent the backflow of cooling liquid into the gap. The ring-shaped protrusion 42 is arranged at this position, which means that under the premise of the same thickness, the ring-shaped protrusion 42 is equivalent to excavating part of the volume at the lower end, so that the volume of the sealing member 40 is reduced compared with the same thickness of the sealing member 40. The mounting plate 101 laterally abuts against the side surface of the sealing member 40, causing the sealing member 40 to be extruded and deformed and applying a counterforce to the mounting plate 101, thereby achieving a sealing effect. Since the ring-shaped protrusion 42 reduces the volume of the sealing member 40, the deformation amount is also reduced, and the counterforce applied to the mounting plate 101 is also reduced, thereby avoiding damage to the mounting plate 101.

[0062] As shown in Figures 4 to 6 , the liquid cooling field controller 100 is in a state before installation. When installed, the mounting plate 101 will be extruded and deformed from one side close to the inlet and outlet pipe 30 to the other side, and will be located on the side surface of the sealing member 40. At this time, the sealing member 40 will also be deformed to cooperate with each other to complete the installation.

[0063] As preferred, the number of the annular protrusions 42 is set to at least two, and at least two of the annular protrusions 42 are arranged in a radial direction of the inlet / outlet pipe 30. In this way, the seal 40 can form at least two lines of defense in the radial direction of the inlet / outlet pipe 30, further avoiding the coolant from flowing back into the gap between the seal 40 and the mounting seat 31.

[0064] Further, the number of the annular protrusions 42 can be set to two, three, five, or the like, and is not limited thereto. The number of the annular protrusions 42 can be determined according to actual conditions. In the present embodiment, the number of the annular protrusions 42 is set to two.

[0065] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features of the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to be within the scope of the present disclosure.

[0066] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
