The invention provides a double-layer flow air blower, a vehicle-mounted air conditioning box and an automobile air conditioner. The double-layer-flow blower comprises a volute, a flow guide plate and a flow guide plate, wherein the interior of the volute is divided into an upper-layer-flow space and a lower-layer-flow space; a first air outlet is formed in the volute and communicated with the upper layer flow space, and a second air outlet is formed in the volute and communicated with the lower layer flow space; the first air outlet and the second air outlet are formed in the two axial sides of the volute. The impeller assembly comprises an upper impeller, a lower impeller and a partition plate used for separating the upper impeller from the lower impeller, and blades of the upper impeller and blades of the lower impeller are backward-inclined blades; and the driving mechanism drives the impeller assembly to rotate. The impeller assembly is arranged to be the backward inclined blades, and the air outlet direction of the volute can be set to be air outlet in the axial direction of the volute; therefore, when the air conditioning box is arranged, the axial direction of the air blower is consistent with the air inlet direction of the indoor heat exchanger, and the overall size of the air conditioning box is reduced.

    本发明提供了一种双层流鼓风机、车载空调箱及汽车空调。该双层流鼓风机包括:蜗壳,所述蜗壳内部分隔为上层流空间和下层流空间;所述蜗壳上设有第一出风口,与所述上层流空间相连通,所述蜗壳上设有第二出风口,与所述下层流空间相连通;所述第一出风口和所述第二出风口设于所述蜗壳的轴向两侧;叶轮组件,包括上叶轮、下叶轮以及用于隔开所述上叶轮和所述下叶轮的隔板,所述上叶轮和所述下轮的叶片为后倾叶片;驱动机构,驱动所述叶轮组件转动。本发明通过将叶轮组件设置为后倾叶片,可将蜗壳的出风方向设置为沿其轴向出风;进而在布置空调箱时,可以实现鼓风机轴向与室内换热器的进风方向一致的布局,降低空调箱整体的体积。
