[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Refer to Figure 1 And Figure 2 As shown in, a cooling device for an autopilot control device includes a compression refrigerating machine 1 and a sealed bladder 6. The compression refrigerating machine 1 is connected to the heat exchanger 2. The heat exchanger 2 is communicated with the sealed bladder 6 through the exhaust pipe 8. The heat exchanger 2 is communicated with the pressurizing pump 3 through the diversion pipe 9. The pressurizing pump 3 is communicated with the sealed bladder 6 through the intake pipe 5. The compression refrigerating machine 1 and the pressurizing pump 3 are both electrically connected to the autopilot chip body 14 disposed inside the sealed bladder 6. The inside of the sealed bladder 6 is filled with an insulating cooling gas 13 that soaks outside the autopilot chip body 14. The autopilot chip body 14 is electrically connected to various electronic components of the vehicle through a composite cable 12 laid in a cable integrated sleeve 11. A temperature sensor 15 electrically connected to the autopilot chip body 14 is disposed on the inner wall of the sealed bladder 6.

[0021] Refer toFigure 1 and Figure 2 The sealed bladder 6 is hermetically connected to the intake pipe 5 and the exhaust pipe 8 through bellows 7. Such a setting facilitates the bellows 7 to protect the interfaces where the intake pipe 5 and the exhaust pipe 8 are connected to the sealed bladder 6, improving the flexibility during the installation of the device.

[0022] Refer to Figure 1 A gas flow velocity sensor 4 is installed on the diversion pipe 9. The gas flow velocity sensor 4 is electrically connected to the main body 14 of the autonomous driving chip. Such a setting facilitates the main body 14 of the autonomous driving chip to monitor the velocity of the cooling gas flow in real time and regulate the cooling efficiency.

[0023] Refer to Figure 1 and Figure 2 An air replenishing valve 10 is hermetically installed on the sealed bladder 6. The air replenishing valve 10 is a one-way valve. Such a setting facilitates replenishing the insulating cooling gas 13 into the sealed bladder 6 through the air replenishing valve 10 when needed, ensuring the cooling efficiency and the insulating protection effect.

[0024] Refer to Figure 2 The insulating cooling gas 13 is sulfur hexafluoride gas. Sulfur hexafluoride gas is a commonly used inert insulating gas, widely used in power equipment and electronic equipment, with excellent insulating performance and arc extinguishing ability, being a stable gas that is colorless, odorless, non-toxic, and non-flammable, having good safety, and acting as an excellent insulating and cooling medium in this device.

[0025] Refer to Figure 3 The cable integrated sleeve 11 includes a rubber tube sleeve 1101. A composite cable 12 is laid inside the rubber tube sleeve 1101. The composite cables 12 are fixed and sealed by an insulating adhesive 1102. Such a setting can fix the composite cables 12 by using the insulating adhesive 1102 and seal the rubber tube sleeve 1101, reducing gas leakage.

[0026] Refer to Figure 2 The number of temperature sensors 15 is not less than two. The temperature sensors 15 are arranged at the corners inside the sealed bladder 6. Such a setting facilitates using multiple temperature sensors 15 to monitor the temperatures of all dead corners inside the sealed bladder 6 simultaneously, and improving the accuracy of temperature monitoring through cross-comparison.

[0027] Working principle: When using this device, the main body 14 of the autonomous driving chip is electrically connected to various electronic components of the vehicle through the composite cable 12, so as to facilitate the main body 14 of the autonomous driving chip to control the vehicle's actions. During the process of the main body 14 of the autonomous driving chip controlling the vehicle to drive autonomously, the main body 14 of the autonomous driving chip generates heat. The temperature sensor 15 monitors the temperature inside the sealed capsule 6 in real time and feeds it back to the main body 14 of the autonomous driving chip. When it is detected that the temperature inside the sealed capsule 6 is higher than the set value, the main body 14 of the autonomous driving chip controls the compression refrigerator 1 and the pressure pump 3 to start. The compression refrigerator 1 cools the insulating cooling gas 13 flowing in the diversion pipe 9 through the heat exchanger 2, and the pressure pump 3 pushes the low-temperature insulating cooling gas 13 to take away the heat inside the sealed capsule 6. Since the insulating cooling gas 13 completely immersively wraps around the outside of the main body 14 of the autonomous driving chip, the contact area of heat exchange between the insulating cooling gas 13 and the main body 14 of the autonomous driving chip is increased, so that the main body 14 of the autonomous driving chip can be cooled efficiently and quickly. At the same time, the insulating cooling gas 13 can also provide an arc extinguishing and insulation protection function for the main body 14 of the autonomous driving chip, further improving the safety of autonomous driving.
