摘要
随着新能源汽车的发展,传统座舱向智能座舱转变,相应的电气功能件也越来越多。5G天线、HUD等占据了较大的仪表板内空间,对前除霜格栅的性能提出了较大的挑战。目前常规的前除霜格栅的Y向尺寸基本大于600 mm,但是一方面为了增强造型的可观性,另一方面由于智能化座舱的普及,前除霜格栅Y向尺寸受到很大限制。基于此,本文采用计算流体动力学(CFD)分析方法,研究在智能座舱极限空间下的仪表板前除霜性能,并提出优化方案以实现高性能除霜的效果。改进后的仪表板前除霜性能得到显著提升,超过了国际标准要求。
With the development of new energy vehicles,traditional cockpits are shifting to⁃wards intelligent cockpits,resulting in an increasing number of electrical components.5G antennas,HUDs,and other components occupy a large space inside the dashboard,posing significant chal⁃lenges to the performance of the front defrost grille.The Y-dimension of conventional front defrost grilles is generally greater than 600 mm.However,on one hand,in order to enhance the aesthetics of the design,and on the other hand,due to the popularization of intelligent cockpits,the Y-dimension of the front defrost grille is greatly restricted.Based on this,the computational fluid dynamics(CFD)analysis method is adopted to study the defrosting performance of the dashboard front defrost grille in the limited space of the intelligent cockpit,and an optimization scheme is proposed to achieve highperformance defrosting.The improved defrosting performance of the dashboard front defrost grille has been significantly improved,surpassing international standards requirements.
