The invention relates to a fan
system, an air conditioner outdoor unit and a heat exchange method of the air conditioner outdoor unit, and belongs to the technical field of air conditioners. According to the mainly adopted technical scheme, the fan
system comprises at least two fan blades and a motor, wherein each
fan blade comprises a plurality of blade bodies. The motor is connected with the fan blades and used for driving the fan blades to rotate. The fan
system is applied to the air conditioner outdoor unit and used for carrying out acting on
airflow at least two times, so that heat exchange between external
airflow and a
heat exchanger in the air conditioner outdoor unit is carried out. The air conditioner outdoor unit comprises the fan system. According to the heat exchange method of the air conditioner outdoor unit, the fan system is adopted, so that heat exchange between the external
airflow and the
heat exchanger in the air conditioner outdoor unit is carried out. The fan system, the air conditioner outdoor unit and the heat exchange method of the air conditioner outdoor unit are mainly used for improving the acting ability and efficiency of the fan system on the airflow and ensuring the recirculation
air volume generated by the fan system, so that the heat exchange effect of the
heat exchanger of the air conditioner outdoor unit is improved.
