装载机冷却系统若设计不合理,将导致其发动机、液压系统、变矩器过热,造成装载机性能下降,甚至引起故障。我们对某5吨装载机散热不良问题进行研究,先对其冷却系统热平衡进行试验,再对其冷却系统、发动机、整机结构及布置空间进行分析,然后通过加装防热风回流装置、改善散热器布置、改进冷却风扇和导风罩,提升了冷却系统的性能,从而解
If the design of the loader cooling system is not reasonable, it will lead to overheating of the engine, hydraulic system and torque converter, causing the performance of the loader to decline or even cause malfunction. We study the problem of poor cooling of a 5-ton loader. First we test the thermal balance of its cooling system, then analyze its cooling system, engine, machine structure and layout space, and then through the installation of anti-hot air return device to improve heat dissipation The arrangement of the device, the improved cooling fan and the draft shield improve the performance of the cooling system and thus the solution
