LIQUID COOLING SYSTEM, CONTROL METHOD AND CONTROL DEVICE APPLIED THERETO

This application provides a liquid cooling system, a control method applied to the liquid cooling system, and a vehicle, and relates to the field of artificial intelligence, autonomous driving, or intelligent driving, and may be applied to an intelligent vehicle, a networked vehicle, and an autonomous driving vehicle. The liquid cooling system includes a pump, a heat exchanger, a vehicle-mounted control module, and a plurality of vehicle-mounted components, where the plurality of vehicle-mounted components include an intelligent driving control component. The pump is configured to deliver liquid to the plurality of vehicle-mounted components, to dissipate heat for the plurality of vehicle-mounted components. The vehicle-mounted control module is configured to determine a rotation speed of the pump based on pump rotation speed requirements of the plurality of vehicle-mounted components. The liquid cooling system provided in this application can meet both a heat dissipation requirement of the intelligent driving control component and an energy saving requirement of an entire vehicle.
