THERMAL MANAGEMENT SYSTEM AND CONTROL METHOD THEREOF

A thermal management system includes a first liquid pipeline, a second liquid pipeline and a switching valve group, and the switching valve group is connected between the first liquid pipeline and the second liquid pipeline. The switching valve group can be switched between a first working position and a second working position; when the switching valve group is at the first working position, a circulation loop having the first liquid pipeline and a circulation loop having the second liquid pipeline are two circulation loops in which liquid flow circulations do not interfere with each other; and, when the switching valve group is at the second working position, the first liquid pipeline and the second liquid pipeline form a series circulation loop. The thermal management system can meet the working requirements of a device corresponding to a first heat exchanger and a device corresponding to a second heat exchanger.
