The invention relates to an integrated ventilation cooling system of a locomotive, which comprises a side wall filter and a variable flow water-cooling radiator which are respectively arranged on the outer side and the inner side of an opening in the side wall of the locomotive; the ventilator is mounted on the chassis of the locomotive and is connected and sealed with the variable-flow water-cooling radiator through a transition air duct, and an air outlet of the ventilator is connected and sealed with an air duct of the chassis; an air inlet of the traction motor is connected with an air outlet of the underframe air duct, and an air outlet of the traction motor exhausts cooled air into external air; and an air inlet of the main generator motor is connected with an air outlet of the underframe air duct, and an air outlet of the main generator motor exhausts cooled air into external air. Converter system cooling, main motor cooling and traction motor cooling are systematically fused, ventilation cooling of multiple systems is completed through one ventilator, the space of the whole vehicle is saved, and the weight of the whole vehicle is reduced.
本发明涉及一种机车集成式通风冷却系统,包括:侧墙过滤器和变流水冷散热器,其分别设置在机车侧墙上开口的外侧和内侧;通风机,其安装在机车的底架上并与变流水冷散热器之间通过过渡风道连接密封,通风机的出风口与底架风道连接密封;牵引电动机,其进风口与底架风道的出风口连接,牵引电动机的出风口将冷却后的空气排出至外界空气中;主发电动机,其进风口与底架风道的出风口连接,主发电动机的出风口将冷却后的空气排出至外界空气中。本发明将变流系统冷却、主发电动机冷却及牵引电动机冷却进行系统融合,实现了一台通风机完成多系统的通风冷却,节省了整车空间,降低了整车重量。
