轮式装载机动力舱热管理系统数值仿真分析草稿

1、装载机动力舱空间有限,舱内布置多个热源与散热器,在作业过程中,。热器布置到动力舱的后端，并在散热器与发 之间设置隔热板，thus，动力舱被分隔为两 马反馈数据，若某一温度过高，则通过此机制提高风扇转速，反之亦然，这就使得发 负载较高，燃油消耗较大。本文重点关注独立散热系统的设置对动力舱结构的影响 and the sequential influence of 散热效。Generally,装载机动力舱空间有限,舱内布置多个热源与散热器,在作业过程中,。热器布置到动力舱的后端，并在散热器与发 之间设置隔热板，thus，动力舱被分隔为两 马反馈数据，若某一温度过高，则通过此机制提高风扇转速，反之亦然
