The invention discloses an air duct structure and a parking air conditioner, relates to the technical field of air conditioners, and solves the problem of high running noise of the parking air conditioner in the prior art. The air duct structure comprises a chassis, a cross-flow fan blade, an evaporator and an evaporator air duct. The evaporator and the evaporator air duct are located on the chassis; an accommodating cavity is formed between the evaporator and the evaporator air duct; and the cross-flow fan blade is located in the accommodating cavity. Compared with a centrifugal fan blade used in the prior art, the cross-flow fan blade is adopted in the air duct structure, on one hand, the rotating speed of the cross-flow fan blade is obviously reduced, the advantage of low noise during operation is achieved, user experience can be improved, and the technical problem that in the prior art, a parking air conditioner is large in operation noise is solved; on the other hand, a motor matched with the cross-flow fan blade is low in running power, the energy efficiency of the whole machine can be improved, and the running duration of the unit can be prolonged by utilizing a battery packwith the same capacity for power supply; and furthermore, the cost of a cross-flow fan is lower than that of a centrifugal fan, and the unit cost can be effectively reduced.

    本发明公开了一种风道结构和驻车空调器,涉及空调技术领域,解决了现有技术中驻车空调器运行噪音大的问题。本发明的风道结构包括底盘、贯流风叶、蒸发器和蒸发器风道,蒸发器和蒸发器风道位于底盘上,并且蒸发器和蒸发器风道之间形成容纳空腔,贯流风叶位于容纳空腔内。本发明的风道结构采用贯流风叶,相比于现有技术中使用的离心风叶,一方面其转速明显降低,具有运行时噪音低的优势,可提升用户体验,解决了现有技术中驻车空调器运行噪音大的技术问题;其次,贯流风叶搭配的电机运行功率低,可以提升整机能效,利用相同容量的电池组供电,可以延长机组运行时长;再次,贯流风机成本较离心风机低,可以有效降低机组成本。
