The invention relates to the technical field of vehicle exhaust, in particular to a silencer, an exhaust cooling system and a vehicle. The silencer is internally provided with at least one cavity, a waste gas inlet, a waste gas outlet and a cold gas inlet are formed in the silencer, and the waste gas inlet is suitable for being connected with an exhaust pipe of an engine; the cold air inlet is suitable for being connected with a cold air supplier, and the waste gas outlet is used for discharging mixed waste gas and cold air in the silencer. The cold air and the waste gas are mixed in the cavity of the fixed silencer, so that the cooling effect on the waste gas is guaranteed, the temperature at the exhaust outlet is reduced, and the rime fog phenomenon at the exhaust outlet when the temperature is low is reduced.

    本发明涉及车辆排气技术领域,特别是涉及一种消声器、排气降温系统及车辆。一种消声器,该消声器内具有至少一个腔室,消声器上设置有废气入口、废气出口及冷气入口,废气入口适于连接发动机的排气管;冷气入口适于连接冷气供应器,废气出口供消声器内混合后的废气和冷气排出。冷气与废气在固定的消声器的腔室中混合,以有利于保证对废气的降温效果,降低排气出口处的温度,淡化温度较低时排气出口的白雾现象。
