摘　　要：为了提高汽车发动机冷却系统的散热效果,该文介绍了发动机冷却系统风扇的基本选型设计方法。首先根据发动机冷却系统散热器性能的计算方法及冷却系统试验结果,给出冷却风量和系统风阻的估算方法,再根据冷却系统各部件间的性能匹配和优化,对冷却风扇进行设计选型及校核计算,从而选出工作效率高且功耗低的风扇。该性能计算及匹配方法对发动机冷却系统热平衡分析具有一定的工程应用价值。An approach is introduced for selecting fan type for engine cooling system to improve the heat dissipation of engine cooling system. Firstly, It is presented the calculation method of cooling air flow and resistance of engine cooling system according to the calculation of engine cooling system heat exchanger dissipation performance and the test results of cooling system, it is discussed the calculation of designing, selecting and verifying for cooling fan, based on the performance of matching and optimization of each component. Therefore, cooling fan should possess higher efficiency and lower power consumption. This method shows a certain value in the application of cooling system heat balance analysis.
