摘　　要：小型液压挖掘机在高温环境下因出现发动机过热现象而无法正常工作。通过从理论上对水箱温度过高原因的分析,对冷却系统的结构布置提出了几种改进方案,并进行了热平衡试验,所选定的方案使冷却系统的各部件得到合理匹配,提高了冷却效果。测试表明,结构布置的改进有效地解决了发动机过热的问题。Due to over-heat phenomenon under high temperature work conditions, small-sized hydraulic excavators can't properly operate. Through a theoretical analysis on the causes of excessive radiator temperature, structural arrangement of the cooling system is improved so that every parts in the system can be rationally matched. Test shown that improvement on structural arrangement can settle engine over-heat problem effectively.
