The invention discloses a redundant cooling tower for rail transit vehicles, which belongs to the technical field of rail transit and comprises an air cooling system, a converter water cooling system and a transformer oil cooling system. The air cooling system comprises a bottom mounting base, a heat exchanger, a multifunctional cabinet body, a main air cooler and a top air inlet duct which are sequentially arranged from bottom to top. The redundant design scheme of double fans, double water pumps, double liquid level sensors and the like is adopted, and the risk that a railway vehicle breaks down and stops running due to faults of the cooling tower can be reduced. On one hand, the risk that the motor train unit is damaged due to water pump faults is reduced, and even if one water pump breaks down, full-speed operation of the motor train unit can be guaranteed; and on the other hand, the service life of the water pumps can be greatly prolonged and the maintenance cost of the cooling tower can be reduced due to the alternate operation mode of the two water pumps.
本发明公开了一种轨道交通车辆用冗余式冷却塔,属于轨道交通技术领域,包括风冷系统、变流器水冷系统和变压器油冷系统;所述风冷系统包括自下向上依次设置的底部安装座、换热器、多功能柜体、主冷风机和顶部进风道。采用双风机、双水泵、双液位传感器等冗余设计方案,可削减冷却塔故障导致轨道车辆机破停运的风险。本发明一方面削减了水泵故障导致动车组机破的风险,即使在一台水泵故障的情况下,也可保障动车组全速运营;另一方面,两台水泵交替运转模式可大大提高水泵的使用寿命,降低了冷却塔维护成本。
