摘　　要：为寻求汽车前风挡玻璃除霜方式,提升除霜效率,文章主要分析了某款车型的除霜风道结构。在稳态计算结果的基础上预测其除霜效果,通过在风道内部添加导叶片对气流进行梳理,除霜效果有了较大提高,并通过瞬态计算得到A,A′,B区霜层全部除干净用时分别为876,996,1314s,并与试验结果进行了比对,满足国家标准的要求。In order to enhance the effect of demisting through seeking the optimization and improve demisting efficiency, this paper describes vehicle demist vent. It detects demisting effect by the result of steady state calculation. An internal guide blade is added into the air duet to lead the airflow, the demisting effect is improved greatly. Time for demisting A, A＇ and B area is 876, 996, 1314 s respectively based on Iransient calculation, which meet the national standards with the comparison to the experiment resuhs.
