Abstract

The defrosting is very important in vehicle. In the paper, some improved proposals to the lack performance of the vehicle windshield defrosting would be discussed by using computational fluid dynamic (CFD) numerical simulation analysis and experiment to validate the improved proposal. The improved proposal including change the angle of the grill of wind outlet, and add grill on the left and right side. The discrepancy of the two methods is in 5%, which is acceptable. By the improved proposal that the windshield defrosting area is increased and also the requirements is satisfied.
