The air supply system of the automobile air conditioner comprises a fresh and return air flow path control module and a draught fan module, the fresh and return air flow path control module is provided with two air inlets and an air outlet, the two air inlets are a fresh air opening and a return air opening respectively, and a rotary air door is rotatably installed in the fresh and return air flow path control module; switching of a full fresh air mode, a full return air mode and a fresh and return air mixed mode is achieved through rotation of the rotary air door. The air conditioner is characterized in that the fan module comprises a turbofan assembly arranged on the downstream of the air outlet. The air supply system has the advantages that the structure is simple, the number of parts is small, the fan module is the turbofan assembly arranged on the downstream of the air outlet, the air flow direction of a turbofan is parallel to the rotating shaft, larger air volume can be output with smaller occupied space, compared with a traditional structure, the size of the whole air supply system can be reduced by about 40%, and application and arrangement are easy; in addition, the partition plate is additionally arranged on the rotary air door, double-layer flow can be achieved, and heating energy consumption of an automobile air conditioner is reduced.

    本发明公开了一种汽车空调的送风系统,包括新回风流路控制模块和风机模块,新回风流路控制模块具有两个进风口和一个出风口,两个进风口分别为新风口和回风口,新回风流路控制模块内可转动安装有一旋转风门,通过旋转风门的转动用于实现全新风模式、全回风模式和新回风混合模式的切换,特点是风机模块包括设置在出风口下游的涡轮风扇总成。优点是结构简单,零件少,风机模块为设置在出风口下游的涡轮风扇总成,涡轮风扇的气体流向平行于转轴,其能在更小的空间占用下输出更大的风量,与传统结构相比,实现整个送风系统的体积能够减小40%左右,易于应用布置;另外通过在旋转风门增加隔板,可以实现双层流,用于降低汽车空调的制热能耗。
