An expansion kettle for a vehicle cooling system and the vehicle cooling system.The expansion kettle comprises a kettle body and a cavity arranged in the kettle body, a liquid inlet and a liquid outlet are formed in the kettle body, a drainage channel matched with the bottom of the kettle body is arranged in the kettle body, and the two ends of the drainage channel are connected with the liquid inlet and the liquid outlet respectively; an exhaust hole and a liquid supplementing hole are sequentially formed in the side face of the drainage channel in the flowing direction of the cooling liquid and both communicate with the cavity. The drainage channel for connecting the liquid inlet with the liquid outlet is formed in the kettle body, and the exhaust hole and the liquid supplementing hole are sequentially formed in the side face of the drainage channel in the flowing direction of the cooling liquid, so that automatic separation of air in the cooling liquid and automatic supplementing of the cooling liquid can be achieved; as the expansion kettle is directly connected in series with the main cooling loop of the motor, the cost investment and the arrangement space of pipelines, pipe clamps and a liquid-gas separator are reduced, and the weight of the cooling system is also reduced.

    一种用于车辆冷却系统的膨胀水壶及车辆冷却系统,膨胀水壶包括壶体以及设置在壶体内部的腔室,壶体上设有进液口及出液口,壶体的内部设有与壶体底部相适配的引流通道,该引流通道的两端分别与进液口、出液口相连,引流通道的侧面沿冷却液流动方向依次设有排气孔、补液孔,排气孔及补液孔均与腔室相连通。通过在壶体的内部设置将进液口与出液口连接的引流通道,并在引流通道的侧面沿冷却液流动方向依次设置排气孔、补液孔,能够实现冷却液中空气的自动分离及冷却液的自动补充;由于直接将膨胀水壶串联连接在电机主冷却回路,减少了管路、管夹、液气分离器的成本投入及布置空间,也减轻了冷却系统的重量。
