The automobile air conditioner double-layer flow HVAC air inlet box comprises a box body, a double-layer impeller and a partition plate, the partition plate is fixedly mounted in the box body, a mounting hole is formed in the middle of the partition plate, an air outlet is formed in the box body, the double-layer impeller comprises two impeller bodies which are coaxially connected, and the double-layer impeller is rotationally connected to the box body and located in the mounting hole in the middle of the partition plate; the two impeller bodies are located in the upper cavity and the lower cavity in a one-to-one correspondence mode respectively, a first connecting part is arranged on the side wall of the double-layer impeller, a second connecting part is arranged on the edge of an opening of an installation hole in the middle of the partition plate, one of the first connecting part and the second connecting part is a convex ring, and the other one is a connecting groove. The convex ring and the connecting groove are annular and extend around the double-layer impeller, and the convex ring is located in the connecting groove. According to the double-layer flow HVAC air inlet box, the possibility of air channeling between the upper cavity and the lower cavity can be reduced, the possibility that unfiltered external air is mixed into internal air is reduced, and the using effect of the double-layer flow HVAC air inlet box is improved.

    本申请涉及一种汽车空调双层流HVAC进风箱,包括箱体、双层叶轮以及隔板,隔板固定安装于箱体内部,隔板中部开设有安装孔,箱体开设有出风口,双层叶轮包括两个同轴连接的叶轮主体,双层叶轮转动连接于箱体且位于隔板中部的安装孔内,两个叶轮主体分别一一对应位于上腔室和下腔室内,双层叶轮侧壁设置有第一连接部,隔板中部安装孔的开口边沿设置有第二连接部,第一连接部与第二连接部中,其中一个设置为凸环,另一个设置为连接槽,凸环和连接槽均呈环形且环绕双层叶轮延伸,凸环位于连接槽内。本申请能够减小上腔室与下腔室之间出现窜风的可能性,减小未经过过滤的外气混入内气的可能性,改善双层流HVAC进风箱的使用效果。
