摘　　要：针对某型大功率轮式拖拉机散热系统过热的情况,分析热平衡试验结果,发现在机罩内部存在热空气再循环现象,并对散热系统提出了改进措施。试验结果表明,改进后的散热系统满足使用要求。Based on overheating phenomena of heat dissipation system in certain high-power wheeled tractor, the paper analyzes the result of heat balance experimentation. It is discovered that there is heat air recycle in the interior of the engine cover, so improvement measures on heat dissipation system are put forward. The experiment shows that improved heat dissipation system can meet the usage requirement.
