Provided is an expansion tank, including a tank body (100), where a first chamber (110), a second chamber (120), and a first through hole (131) through which the first chamber communicates with the second chamber are provided within the tank body; the tank body is provided with a pipe (200) communicating with an interior of the tank body, and a side wall of the pipe is provided with a mixed liquid inlet (210); a second partition (220) is provided within the pipe; one end of the second partition is connected to the side wall of the pipe and the other end of the second partition extends to the mixed liquid inlet so as to form a first channel (230) and a second channel (240) within the pipe; a first end of the first channel is connected to the first chamber, a second end of the first channel is closed, a first end of the second channel is connected to the second chamber, a second end of the second channel is configured to be connected to a water pump (20). The expansion tank has a function of gas-liquid separation, thus there is no need to provide a special liquid-gas separator in a cooling system, thereby facilitating the reduction of the number and the total weight of parts in the cooling system, the reduction of the costs, and facilitating the lightweight of a vehicle. Further provided is a cooling system and a vehicle.
