| 摘 要： | 本文采用CFD数值计算方法辅助风冷发动机冷却系统设计。设计时，首先采用经验方式确定发动机需求的冷却风量及散热功率，并初步确定散热肋片的设计方案；然后，依据CFD计算，考察肋片设计是否合理并根据认定合理的肋片结构确定冷却风道的阻力流量关系，依据这个关系选取风扇；最后在完整设计方案满足CFD计算的前提下，对设计方案进行台架试验。结果表明，理论计算及数值模拟相结合的方式能很好的应用到风冷发动机冷却系统设计中去。

| Abstract: | The paper designs the cooling system for air -cooled engine with CFD. First, it de- termines the cooling air flow and the radiating power required by the engine with the traditional way and sets the preliminary design plan for radiating fins, secondly, analyzes the design reliability of ra- diating fins using CFD, determines the relationship between the resistance and flow rate according to the structure of radiating fins, selects the fan on the basis of the relationship, finally, carries out the bench test for the design plan under the conditions that the plan meets the CFD calculation. The re- sults show that the combination the theoretical calculation and numerical simulation can be used well in design of the air- cooled engine. |
