The invention provides an automobile cooling system, a control method and device and an automobile. The automobile cooling system comprises a radiator and a circular line for circulating a cooling liquid, wherein the circular line is connected to the radiator and sequentially connected with a water pump, a diverter valve and a cooling target unit in series through an output end of the radiator; the cooling target unit comprises at least two parallel branches; each parallel branch comprises a to-be-cooled device; the water pump is used for controlling the flow of the cooling liquid entering thediverter valve; and the diverter valve is used for controlling the flow of the cooling liquid, entering each parallel branch, on the circular line. According to the automobile cooling system, each to-be-cooled device is located on one parallel branch through arranging a plurality of parallel branches, so that the cooling efficiency is improved. Meanwhile, the diverter valve can control the flow of the cooling liquid entering each parallel branch, so that refined control on the cooling temperature is achieved, the condition that various cooling parts work within a lower temperature range is ensured and the cooling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile cooling system, a control method, a device and an automobile. Background technique [0002] In recent years, with the development of electric vehicle technology, electric vehicles have higher and higher requirements in terms of light weight, low energy consumption, and high efficiency. The electrical components targeted by the electric vehicle power cooling system are more significantly affected by temperature. , requiring more refinement of temperature control. [0003] The electric vehicle power cooling system mainly performs liquid cooling and heat dissipation on the drive motor, motor controller and DC / DC converter, and connects these heat dissipation components with water pipes to form a loop for cooling treatment, but the cooling efficiency is low and fine control cannot be achieved . Contents of the invention [0004] The technical problem to be solve...
