When the air conditioner works, the heat dissipation air of the air conditioner passes through the side wall of the shell of the air conditioner outdoor unit, then radiates heat for the condenser in the shell, and finally radiates to the outside through the air outlet. However, the outdoor unit of the air conditioner in the prior art has the following defects: firstly, strict requirements are set between an air outlet of the air conditioner outdoor unit and a wall surface, the distance between the air outlet of the air conditioner outdoor unit and the wall surface cannot be too small, and if the distance is too small, return air is easy to generate for the air conditioner outdoor unit, so that the working efficiency of the air conditioner outdoor unit is greatly reduced; and the air outlet is not externally connected with an air guide component, so that the air conditioner outdoor unit in the prior art has higher requirements on the installation position, the installation occasion is limited, and the applicability is not strong; secondly, only one condenser can be installed in the air conditioner outdoor unit, so that the energy consumption is high and the working efficiency is greatly reduced during working; and the axial flow fan blade is adopted in the conventional air conditioner outdoor unit, so that the noise is high during working, the interference to users is high, and the air conditioner outdoor unit is not energy-saving and environment-friendly. Due to the reasons, the existing wall-mounted and floor-type split air conditioners are not more and more suitable for decoration spaces of the existing small-area rooms.

Meanwhile, due to the limitation of installation space, the existing air conditioner external unit cannot be installed outside a house, and only the internal unit or the external unit of the air conditioner can be embedded in a wall body and a window body. In addition, most of the existing air conditioner external units use axial flow fan blades to perform heat exchange treatment on the condenser, and a part of the existing air conditioner external units also use centrifugal fan blades, so that the axial flow fan blades and the centrifugal fan blades can well meet the performance requirements; however, the axial flow fan blade requires a large space, and the use of a single axial flow fan blade cannot meet the installation requirement under the general model size; for the centrifugal fan blade, the air quantity can meet the requirement, but the power and the noise are raised to unacceptable height by excessive static pressure energy.

Therefore, to the design space more and more miniaturization problem in current house and to the restriction to installation space, in order to guarantee that the house space can effectively be utilized, current air conditioner design all can not satisfy use, installation requirement, and the urgent need designs a section can inlay the hidden air conditioner of dark dress in wall body or window form inside with the outer machine of air conditioner.
