摘要
通过STAR-CCM+软件对某重型车前挡风玻璃进行了除霜分析,以求出挡风玻璃附近气流的速度、车内流场的分布以及不同时间节点的霜层厚度,结果显示该车的除霜效果达不到设计要求,需对其除霜出风口进行优化设计。随后,对优化后的结构再次进行除霜分析计算,结果表明,优化除霜出风口后的除霜效果能很好地满足国家相关标准要求,分析方法及结果能够为重型车的空调除霜系统设计提供理论依据。
A defrosting analysis in a heavy truck windshield is CCM＋ software. The distributions of velocity and flow field in t the windshield are obtained, as so as the thick of the frost diffe The results show that the effect of the defrosting is not good, design on defrosting air outlet is taken. The defrosting of the opt analyzed. The results show that, the standard well after the air outlet is op results could offer the theory reasons conducted by STAR- he internal truck near rent and time is acquired. the optimization imlzatlon structure is effect of defrosting is satisfied the national timized, which the me for the design of air thod of analysis and the conditioning defrostingsystem of the heavy truck.
