商用车驾驶室除霜分析

The Deicing Research of Commercial Vehicle Cab

随着汽车法规的进一步健全,国家对商用车风窗玻璃除霜系统的性能要求及试验方法做了明确的规定。所以,建立一个良好的除霜系统是非常重要的。运用Fluent软件,采用k-!的RNG数学模型对商用车某车型进行了流场和温度场的模拟,找出了风道设计上的某些不足,给出相关的改进意见和方案。改进后的暖风风管成功地通过了除霜的国家标准。分析出的结果与实际环境模拟试验结果有良好的吻合。此方法的应用将在很大程度上缩短HVAC的设计周期。

In further healthy along with the automobile laws and regulations,our country made a definitely rule about commercial vehicle cab deicing system.Therefore,establishing a good deicing system is very important.This article used k-ε,RNG mathematical model to carry on the flow field and the temperature field simulation to the commercial vehicle cab,discovered in the air duct design insufficiencies, and produced the correlation the improvement opinion and the plan.After the improvement, air duct succeeded passing the national standard which deicing. Analyzing result and the actual environment simulation test resuit has good tallying,this method apUcation will reduce the design cycle of HVAC in the very great degree.
