摘　　要：某项目的汽车空调箱总成在全冷、吹面的模式下风量不满足设计要求,为了提高总风量,设计人员针对鼓风机叶轮和蜗壳进行了设计优化,选取不同的蜗壳型线渐开角和风扇叶轮半径,并使用某商业流体数值仿真软件进行了仿真模拟,选取了最优取值,并通过快速样件实验进行了最终验证,证明了优化方案的可行性,最终空调箱总成的风量和噪音均满足客户要求。To meet the requirements of the air conditioning box assembly in air volume and noise,the design-ers optimized the blower and volute module.They did some simulation work on different radials of the fan and different spiral angles of the scroll using a commercial simulation software and picked the best one of these results.They also did some experiments in a rapid prototype to prove the fea-sibility of the optimization.The air volume and noise of the air conditioning box assembly can meet the customer’s requirements.
