Abstract: A liquid cooling system and a control method thereof are disclosed. The liquid cooling system includes at least two second-level liquid circulation loops and a cooling control apparatus. One second-level liquid circulation loop is provided with a circulating pump configured to control a liquid flow and a sensing apparatus configured to acquire liquid sample data. The control method includes acquiring liquid sample data using sensing apparatuses of a liquid cooling system; implementing sharing of the liquid sample data of the sensing apparatuses using a cooling control apparatus, performing analytical processing on the liquid sample data, and calculating a circulation regulation value of circulating pumps; and sending the circulation regulation value to the circulating pumps using the cooling control apparatus, such that the circulating pumps run according to the circulation regulation value.

Abstract: A heat dissipation controller is connected to a sensor and a water pump such that the controller correspondingly adjusts the water pump according to the current pressure difference and a preset pressure difference, to control a flow capacity of coolant flowing into a branch water pipe, until an absolute value of a difference between the current pressure difference and the preset pressure difference is less than or equal to a preset error amount. The controller can adjust the flow capacity of the coolant flowing into the branch water pipe to effectively ensure that flow capacities of coolant in all branch water pipes are distributed evenly, and to effectively improve stability of the heat dissipation apparatus.

Abstract: A lens control method is applied to a camera module with an OIS motor. The module includes a lens, an OIS motor, an OIS motor driver module, and an imaging sensor. The method includes: obtaining a first speed and a first direction of a to-be-photographed object in a moving process, an object distance between the to-be-photographed object and the lens, and an image distance between the lens and the imaging sensor; calculating a second speed and a second direction based on the first speed, the first direction, the object distance, and the image distance; and sending a control signal to the OIS motor driver module, so that the OIS motor driver module drives the OIS motor to control the lens to move at the second speed and in the second direction.
