摘　　要：针对矿用汽车冷却系统中设计过程,以发动机处于恶劣运行工况作为研究对象,采用无因次系数法对风扇及散热器参数进行优化设计。以首钢重汽正在设计中的大型电动轮自卸车为例,对所设计的风扇及散热器进行试验,根据实验数据绘制特性曲线,并对风扇和散热器进行匹配,结果表明该方法可行性较强。Focused on the design process of cooling system for mining truck,author tried to optimize the main parameters of cooling fan by using dimensionless coefficient method,during the engine operating in bad conditions.The large mining dump-truck during manufacturing process as example,this work in-cluded drawing characteristic curves of actual fan according the test data,matching the fan and the radiator which was designed and get the desired results.It was showed that the method is simple and practicable.
