The invention discloses a design method for a defrosting air duct of an automobile air conditioner, and belongs to the technical field of automobile air conditioners. The shape of an air conditioner outlet is observed, whether a clamping structure exists at the air conditioner outlet position or not is judged, and if the clamping structure exists, a transition air duct needs to be designed; if the clamping structure does not exist, a transition air duct does not need to be designed; the modeling of the front defrosting grid is observed, the length of the defrosting grid and the Y-direction length of the A area of the automobile windscreen are compared, and if the conditions are met, the structure of the defrosting air duct is not limited; if not, whether the front defrosting grid blades are provided with guide blades or not is observed, and if the front defrosting grid blades are provided with the guide blades and the height of the guide blades is within a certain range, the defrosting air duct structure is not limited; if the front defrosting grid is not provided with the guide blades, a guide structure needs to be designed at the butt joint of the defrosting air duct and the front defrosting grid; according to the method, the structure scheme of the defrosting air duct can be quickly selected before CFD analysis in the early stage of project development, the later defrosting performance test passing rate is increased, and the development time is saved.

    本发明公开了一种汽车空调除霜风道的设计方法,属于汽车空调技术领域,观察空调出口形状,判断空调出口位置是否有卡接结构,若有卡接结构,则需要设计过渡风道;若没有卡接结构,则不需要设计过渡风道;观察前除霜格栅造型,比较除霜格栅长度和汽车风窗玻璃A区Y向长度,若满足条件,则除霜风道结构无限制;若不满足,则观察前除霜格栅叶片是否有导向叶片,若有导向叶片,且导向叶片高度在一定范围内,则除霜风道结构无限制;若前除霜格栅无导向叶片,则除霜风道与前除霜格栅对接处需要设计导向结构;本发明能够在项目开发前期在CFD分析之前,快速选择除霜风道的结构方案,提高后期除霜性能试验通过率,节省开发时间。
