This dissertation describes in detail about the operation principle of cooling system , the hardware circuit design and software design of the single chip control system . being different to the structure collation method of traditional cooling system , this system divided the whole system into two parts : cooling system for engine and cooling system for hydraulic oil system , and both of them are controlled by one singlechip
这种电液混合驱动冷却方式可以使风扇离开发动机而灵活布置,克服了传统驱动方式的各种弊端,减小了风扇的径向间隙,提高了容积效率,降低了能耗,并有效解决了发动机和液压传动系统的过热问题。论文对该系统的工作原理、硬件组成、软件设计作了详细论述。
