In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0038] During the actual vehicle testing and verification of the intelligent driving domain controller, since the domain controller is an early R&D product and needs to be installed on a logistics vehicle for actual vehicle testing and verification, the installation environment cannot meet the heat dissipation requirements of the controller.

[0039] During the project testing and verification process, the controller often freezes / crashes due to overheating, the perception camera and the domain controller screen do not match, the screen image is always stuck at a previous moment, and the domain controller is in a frozen / crashed state, resulting in the loss of test and verification data, affecting the overall testing and verification progress of the domain controller.

[0040] Combination Figure 1 As shown, according to a specific embodiment of the present application, a heat dissipation system for testing a domain controller is provided.

[0041] Specifically, Figure 1 As shown, the heat dissipation system for domain controller testing includes: a shell 10, a cooling device 20, and an installation component 30, the shell 10 has a accommodating cavity 11; the cooling device 20 is connected to the shell 10, and the cooling device 20 is used to construct at least one cooling channel in the accommodating cavity 11; the installation component 30 is connected to the shell 10, and the installation component 30 has a connecting portion for connecting to the domain controller 40 to be tested, and the installation component 30 is movably arranged in the accommodating cavity 11 along a first direction, so that when the domain controller 40 to be tested is connected to the installation component 30, the domain controller 40 to be tested and the at least one cooling channel can be arranged heat exchangeably.

[0042] By applying the technical solution of the present invention, the shell 10 has a accommodating cavity 11, the cooling device 20 is connected to the shell 10, the cooling device 20 is located in the accommodating cavity 11, the cooling device 20 is configured as at least one cooling channel, the mounting component 30 is connected to the shell 10, the mounting component 30 is connected to the domain controller 40 to be tested, when the mounting component 30 is movable in a first direction in the accommodating cavity 11, the domain controller 40 to be tested is also movable in the first direction in the accommodating cavity 11, at this time, heat exchange can be performed between the domain controller 40 to be tested and the cooling channel, thereby solving the technical problem of heat dissipation difficulty in the domain controller testing and verification process in the prior art.

[0043] Specifically, the cooling channel includes an air-cooling channel, the cooling device 20 includes an air-cooling component, the air-cooling component includes an intake fan group 21 and an exhaust fan group 22, the intake fan group 21 and the exhaust fan group 22 are respectively arranged on two opposite side walls 12 of the housing 10, and an air-cooling channel is formed between the intake fan group 21 and the exhaust fan group 22. In this embodiment, the intake fan group 21 and the exhaust fan group 22 are designed as a combination of dual variable-speed intake fans and dual variable-speed exhaust fans, which is more conducive to air circulation and improves air-cooling heat dissipation efficiency, and both sides of the domain controller 40 to be tested can effectively dissipate heat.

[0044] Specifically, the suction fan group 21 includes a plurality of suction fans 211, which are arranged at intervals along the second direction on the side wall 12 where the suction fan group 21 is located. The plurality of suction fans 211 inhale air through the rotational movement of the fans. The intervals between the plurality of suction fans 211 can more effectively cover the entire space and improve the ventilation effect; the interval setting can ensure that the air flows more evenly and avoid the occurrence of local dead corners or poor ventilation; the intervals between the plurality of suction fans 211 can reduce mutual interference between the suction fans, reduce noise and vibration, and the interval setting can facilitate the maintenance and cleaning of the suction fans 211. The exhaust fan group 22 includes a plurality of exhaust fans 221, which are arranged at intervals along the second direction on the side wall 12 where the exhaust fan group 22 is located, which can increase the circulation speed of the air and improve the ventilation effect. The plurality of suction fans 211 are arranged one-to-one with the plurality of exhaust fans 221, and each suction fan 211 is arranged at a height level with the corresponding exhaust fan 221.

[0045] Optionally, each suction fan 211 is arranged flush with the corresponding exhaust fan 221 in order to ensure that the suction fan 211 inhales air through the rotation of the fan, and then exhausts the indoor air to the outside through the rotation of the exhaust fan 221. The flush arrangement of the height can make the suction fan 211 and the exhaust fan 221 work together more effectively to form a more stable ventilation system, which can ensure the balance of exhaust and suction, thereby improving the efficiency of the entire ventilation system. If the heights of the multiple exhaust fans 221 and the suction fan 211 are not arranged flush, the ventilation system may work unevenly, the ventilation effect in some areas may be affected, and even the ventilation effect in some areas may be poor.

[0046] Specifically, the cooling channel includes a liquid cooling channel, the cooling device 20 includes a liquid cooling component, the liquid cooling component includes a liquid cooling pipe, a cooling liquid medium is arranged inside the liquid cooling pipe, and the cooling liquid medium is usually water or a mixture of water and a coolant. The outer surface of the domain controller 40 to be tested has heat dissipation fins, and adjacent heat dissipation fins form heat dissipation grooves. When the heat dissipation fins contact each other to form grooves, heat can be more effectively conducted to the surrounding environment, thereby reducing the device temperature and improving the heat dissipation effect. When the domain controller 40 to be tested is connected to the installation component 30, the liquid cooling pipe is located in the heat dissipation groove, and the size of the liquid cooling pipe needs to match the heat dissipation groove.

[0047] Optionally, when the installation component 30 moves, the domain controller 40 to be tested moves accordingly. At this time, the cooling liquid medium flowing in the liquid cooling pipe located in the heat dissipation groove can effectively absorb the heat on the surface of the domain controller 40 to be tested, and then flow out through the pipe to achieve the heat dissipation effect. The outer surface of the domain controller 40 to be tested has heat dissipation fins. The heat dissipation fins are a device for heat dissipation. The heat dissipation principle is mainly to accelerate the conduction and dissipation of heat by increasing the surface area. When the domain controller 40 to be tested generates heat, the heat dissipation fins conduct the heat to its surface, and then transfer the heat to the surrounding air or other media by radiation, convection and conduction, thereby achieving the heat dissipation effect. This system uses the heat dissipation fins on the outer surface of the liquid cooling component and the domain controller 40 to be tested to jointly dissipate heat, which can better reduce the temperature of the domain controller 40 to be tested during testing, and the heat dissipation effect is better.

[0048] Specifically, the first central axis of the suction fan group 21 and the second central axis of the exhaust fan group 22 are arranged to overlap, and the liquid cooling pipe has a third central axis, and the first central axis is arranged perpendicular to the third central axis. The first central axis of the suction fan group 21 and the second central axis of the exhaust fan group 22 are arranged to overlap to ensure that there are no obstacles between them and the air can flow smoothly. This ensures that the air can be effectively sucked in and discharged, thereby achieving a better ventilation effect. In addition, the axis overlap setting can also reduce the resistance of the system and improve the efficiency of the entire ventilation system. The third central axis of the liquid cooling pipe is arranged perpendicular to the first central axis of the suction fan group 21 so that the liquid cooling pipe and the suction fan group 21 can cover more heat dissipation surfaces during the heat dissipation process, thereby increasing the heat dissipation efficiency. In addition, the vertical setting can also improve the efficiency of air circulation, so that heat is taken away more quickly, and the heat dissipation effect is further improved.

[0049] Specifically, the first direction is a height direction of the shell 10 , and / or, the first direction is a length direction of the shell 10 , and / or, the first direction is a width direction of the shell 10 .

[0050] Figure 1 The wire hole 101 is also shown.

[0051] Specifically, the mounting assembly 30 includes a support arm 31, at least one of the support arms 31 is arranged, the first end of the support arm 31 is connected to the housing 10 through a suction cup 32, the second end of the support arm 31 forms a connecting portion, the connecting portion formed by the second end of the support arm 31 is connected to the domain controller 40 to be tested through a fixing bolt, and the second end of the support arm 31 is movably arranged along a first direction. The support arm 31 can provide a stable supporting force to prevent the domain controller 40 to be tested from tilting or collapsing during the test, and the support arm 31 can withstand a load of a certain weight to ensure the stability and safety of the domain controller 40 to be tested. The support arm 31 in this embodiment has an adjustable function, and the support height or angle can be adjusted as needed to adjust the domain controller 40 to be tested to a suitable heat dissipation height.

[0052] Specifically, the support arm 31 includes a sleeve and a swivel, wherein an internal thread is provided inside the sleeve, and an external thread is provided on the outer surface of the swivel, wherein at least a portion of the swivel is located inside the sleeve, and the swivel can be rotated so that the swivel can be movably arranged along a first direction. The internal thread inside the sleeve is meshed with the external thread provided on the outer surface of the swivel, and the support height of the support arm 31 can be adjusted by rotating the swivel so that the swivel can be moved along the first direction.

[0053] Specifically, a slide rail is provided on the housing 10, and the suction cup 32 is connected to the slider, which is slidably provided on the slide rail so that the installation component 30 can be movably provided along the extension direction of the slide rail. The slider is usually used to support and guide the load object, and the suction cup 32 is connected to the slider, and the suction cup 32 can effectively fix the domain controller 40 to be tested. In this embodiment, four suction cups are used to fix the controller in the cooling system box. The installation component 30 moves along the extension direction of the slide rail through the slider, thereby driving the domain controller 40 to be tested to move along the extension direction of the slide rail.

[0054] Specifically, the heat dissipation system for testing the domain controller further includes a temperature detection device 50 . At least one temperature detection device 50 is provided. The temperature detection device 50 is used to detect the temperature of the domain controller 40 to be tested.

[0055] Specifically, the temperature detection device includes a surface-mounted temperature probe. The removable surface-mounted dual temperature probe can select the best probe arrangement position according to the different temperature distribution fields of different controllers. At the same time, the dual probes can realize redundant design to ensure system reliability. The dual probe setting will not affect the operation of the entire domain controller test cooling system in the event of a probe failure. In this embodiment, the optimal arrangement positions of the two temperature probes are determined according to the temperature field distribution of the domain controller 40 product to be tested, and the two removable surface-mounted temperature probes are pasted to the determined optimal arrangement positions.

[0056] It should be noted that the working principle of the surface-mount temperature probe is mainly to use temperature-sensitive elements (such as thermistors, thermistors, etc.) to sense changes in ambient temperature and convert such changes into electrical signal outputs. When the temperature changes, the resistance or capacitance value of the temperature-sensitive element will also change accordingly, thereby changing the current or voltage in the circuit. By measuring the change in current or voltage, the temperature value of the environment can be obtained. Surface-mount temperature probes usually have the characteristics of fast response, accurate measurement and easy use. Using surface-mount temperature probes to measure the temperature of the domain controller 40 to be tested in this heat dissipation system can more quickly perform heat dissipation processing based on the temperature value.

[0057] Specifically, the heat dissipation system for testing the domain controller also includes a controller, which is electrically connected to the temperature detection device 50, and the controller is electrically connected to the cooling device 20, and the controller is used to control the working state of the cooling device 20 according to the detection signal of the temperature detection device 50. The heat dissipation system for testing the domain controller compares the detection signal of the temperature detection device 50 with the set temperature threshold, thereby controlling the working state of the cooling device 20 according to different temperature detection values. The specific steps are as follows:

[0058] S1, the system compares the temperature values ​​of temperature probe 1 and temperature probe 2, and takes the larger value of the two as the temperature detection value of the domain controller 40 to be tested;

[0059] S2, start the system, and set the system temperature threshold 1, temperature threshold 2 and temperature threshold 3 according to the characteristics of the domain controller 40 to be tested, where temperature threshold 1 is less than temperature threshold 2 and less than temperature threshold 3;

[0060] S3, comparing the temperature detection value of the domain controller 40 to be tested with the set temperature threshold. When the temperature detection value of the domain controller 40 to be tested is ≥ the set threshold 1, but < the temperature threshold 2, the suction fan group 21 and the exhaust fan group 22 are automatically started and run at a low speed, and cooperate with the liquid cooling pipe to dissipate heat for the domain controller 40 to be tested;

[0061] S4, when the temperature detection value of the domain controller 40 to be tested is greater than or equal to the set threshold value 2, but less than the temperature threshold value 3, the suction fan group 21 and the exhaust fan group 22 run at a high speed, and cooperate with the liquid cooling pipe to dissipate heat for the domain controller 40 to be tested with higher efficiency;

[0062] S5. When the temperature detection value of the domain controller 40 to be tested is ≥ the set threshold value 3, the suction fan group 21 and the exhaust fan group 22 maintain high speed operation, and the alarm device sends out an alarm message.

[0063] Specifically, the heat dissipation system for testing the domain controller also includes an alarm device, which is electrically connected to the controller. Through the electrical connection, the controller and the alarm device can realize real-time information transmission and response. The controller is used to control the alarm device to perform an alarm action when the temperature detection device 50 detects that the temperature of the domain controller 40 to be tested is greater than the threshold. In this embodiment, when the temperature detection value of the domain controller 40 to be tested is greater than or equal to the set threshold 3, the suction fan group 21 and the exhaust fan group 22 maintain high speed operation, and the alarm device sends an alarm message.

[0064] It should be noted that the heat dissipation system for testing the domain controller also includes that when the alarm device sends out an alarm message, the display screen of the recorder can view and monitor the temperature information of the domain controller 40 to be tested in real time, and automatically save the historical monitored temperature data of the domain controller 40 to be tested to the memory card, which can be copied to the computer through the memory card to provide reference data for the subsequent product thermal management design.

[0065] Specifically, at least one side wall 12 of the housing 10 is formed with a transparent observation window 60 , so as to facilitate observation of the internal operation process of the heat dissipation system for testing the domain controller through the transparent observation window 60 .

[0066] In an alternative embodiment, Figure 2 A control method for a heat dissipation system for testing a domain controller is shown.

[0067] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0068] 1. The present invention designs a heat dissipation system for domain controller testing. By using a dual variable speed suction fan group and a dual variable speed exhaust fan group, air circulation is more conducive to improving air cooling and heat dissipation efficiency. Both sides of the controller can effectively dissipate heat. Combining air cooling components with water cooling components makes the heat dissipation system for domain controller testing have good heat dissipation effect, which can effectively solve the heat dissipation problem in the early domain controller testing and verification process.

[0069] 2. By setting the temperature threshold, the cooling system for the domain controller test compares the temperature detection value measured by the temperature detection device with the set temperature threshold, thereby controlling the working state of the cooling device according to different temperature detection values, so that the suction fan group and the exhaust fan group run at different speeds to achieve the heat dissipation effect, which can intelligently and efficiently dissipate heat for the domain controller to be tested and save energy.
