Currently, tank armor and air conditioning equipment for civilian vehicles mainly adopt the vapor compression refrigeration principle, namely utilizing a refrigerant to release heat in a condenser to change phase into liquid, and absorbing heat in an evaporator to change phase into gas. When the outdoor unit needs refrigeration, the axial flow fan blows air to the condenser to replace heat, so that heat exchange is realized. For example, the air quantity of a 4kW vehicle air conditioner on the condensation side is about 2200 m 3/h, and usually 2 axial flow fans are required, so that the space occupation is large. Meanwhile, the structure of the vehicle body is complex, and the vehicle body is difficult to realize in practical design due to the limitation of space size, weight and other conditions. For example, in view of the development of miniaturization, weight saving and modularization of special vehicles, the height requirements for overhead air conditioners for vehicles are becoming thinner and thinner, the height is influenced by the vertical arrangement of the conventional axial flow fans, and the heat exchange is influenced when the vehicles are driven horizontally.

However, such an induced draft system is rarely applied to a vehicle air conditioner. How to reasonably utilize the induction technology and also consider the change of the air flow field during driving to improve the heat exchange performance of the air conditioner, and is worth focusing.
