  "textContent": "An expansion tank for a vehicle cooling system and a vehicle cooling system. The expansion tank includes a tank body and a chamber provided inside the tank body, a liquid inlet and a liquid outlet are provided on the tank body, a diversion channel matched with a bottom of the tank body is provided inside the tank body, both ends of the diversion channel are respectively connected with the liquid inlet and the liquid outlet, a vent hole and a liquid refill hole are sequentially provided on a side of the diversion channel in a flow direction of a coolant liquid, and the vent hole and the liquid refill hole are both communicated with the chamber. The automatic separation of the air from the coolant liquid and the automatic refill of the coolant liquid can be realized by providing the diversion channel connecting the liquid inlet and the liquid outlet inside the tank body, and sequentially providing the vent hole and the liquid refill hole on the side of the diversion channel in the flow direction of the coolant liquid. Since the expansion tank is directly connected in series to the main cooling circuit of the motor, the cost input and arrangement space of pipelines, pipe clamps, and liquid-gas separators are reduced, and the weight of the cooling system is also reduced.",
