Problems solved by technology
[0004] At present, most post-installed domain controllers generally use fans for heat dissipation or passive heat dissipation. The reliability of fan heat dissipation is not high, and the fans are easy to be damaged; dust is easy to accumulate, and it is difficult to clean; it also makes it difficult for domain controllers to meet high protection levels ( waterproof and dustproof level)
[0005] Most of the pre-installed domain controllers of mass-produced models are water-cooled and share a cooling system with the vehicle, such as Tesla, Xiaopeng Motors, etc.; but for most autonomous driving test vehicles, especially most autonomous driving technology companies, the domain There is a certain risk that the cooling pipeline of the controller is connected to the vehicle cooling system, which will affect the heat dissipation effect of other equipment in the vehicle

The embodiment of the invention provides a vehicle domain controller water-cooling heat dissipation device and system and a using method of the vehicle domain controller water-cooling heat dissipationdevice, and the vehicle domain controller water-cooling heat dissipation device comprises an inlet switching device, an outlet switching device and a water-cooling heat dissipation device. The inletswitching device is connected into the domain controller through the water inlet and used for controlling the inflow direction of cooling liquid before the cooling liquid passes through the water inlet. The outlet switching device is connected to the domain controller through a water outlet and is used for controlling the outflow direction of the cooling liquid after passing through the water outlet; one end of the water-cooling radiator is connected with the switching device so as to cool cooling liquid flowing out of the domain controller, and the other end of the water-cooling radiator is connected with the inlet switching device so as to convey the cooled cooling liquid to the domain controller. By means of the processing scheme, the heat dissipation performance of the vehicle domain controller is improved, and reliable and stable operation of the domain controller is guaranteed.
Description
technical field [0001] The present application relates to the technical field of vehicle domain controllers, in particular to a vehicle domain controller water cooling device, system and usage method thereof. Background technique [0002] The development of new energy vehicles is the only way for my country to move from a big automobile country to a powerful automobile country, and it is a strategic measure to deal with climate change and promote green development. my country's automobiles will continue to develop in the direction of electrification, networking, and intelligence, and the electrical architecture of automobiles will gradually evolve from a distributed ECU architecture to a central domain controller architecture. [0003] The automotive domain controller divides the functions of various parts of the automotive electronics into several domains, such as the power transmission domain, the body electronics domain, and the assisted driving domain, etc., and then use...
