The invention relates to the technical field of vehicles, and particularly discloses a vehicle-mounted air conditioning box, a vehicle-mounted air conditioner and a vehicle, and the vehicle-mounted air conditioning box comprises an air inlet box, a closed mixed flow fan and a distribution box. The closed mixed flow fan comprises a fan shell with an airflow inlet and an airflow outlet, and a front disc and an impeller which are arranged in the fan shell; the impeller comprises a rear disc and a plurality of blades arranged on the rear disc at intervals in the circumferential direction, gas flow channels are formed between the adjacent blades, the front disc covers the multiple blades, an opening is formed in the center of the front disc, and airflow flowing out of the air outlet of the air inlet box enters the opening through the airflow inlet and is discharged out of the airflow outlet through guiding of the gas flow channels. The distribution box is arranged at the airflow outlet. The vehicle-mounted air conditioning box is compact in structure and small in occupied space, and noise is reduced while the air volume is increased.
本发明涉车辆技术领域,具体公开了一种车载空调箱、车载空调及车辆,车载空调箱包括进风箱、闭式混流风机和分配箱。闭式混流风机包括具有气流入口和气流出口的风机外壳和设置在风机外壳内的前盘和叶轮;叶轮包括后盘和在后盘上沿周向间隔设置的多个叶片,相邻叶片之间形成气体流道,前盘罩设于多个叶片,且中心处设有开口,从进风箱的出风口流出的气流经气流入口进入开口内,并经气体流道的导向由气流出口排出,分配箱设置在气流出口处。该车载空调箱结构紧凑,占用空间较小,并且在提高风量的同时,减小了噪音。
